    PER CURIAM:
    This appeal arises from a lawsuit relating to a 2003 mining
    accident in southwestern Virginia, in which coal miner Gregory
    Kennedy   was   fatally   crushed   by   a    continuous   mining   machine.1
    Mollie Kennedy, the administratrix of her husband’s estate, appeals
    from the district court’s award of summary judgment to defendants
    Joy Technologies, Incorporated, and Matric Limited. See Kennedy v.
    Joy Tech., Inc., No. 2:05-cv-00030 (W.D. Va. Oct. 5, 2006) (the
    “Opinion”).2    Mrs. Kennedy contends on appeal that the court erred
    in excluding from evidence a portion of the accident investigation
    report made by the Mine Safety and Health Administration concerning
    her husband’s death (the “MSHA Report”), and in excluding the
    opinions of her causation expert.3           As explained below, we affirm
    the court’s ruling on the expert, reverse its ruling on the MSHA
    Report, vacate the summary judgment award, and remand.

    A continuous miner is a piece of mining equipment that cuts
    coal directly from a coal seam, replacing many conventional mining
    tasks such as drilling and blasting. Consol. Coal v. Marshall, 
    663 F.2d 1211
    , 1213 n.1 (3d Cir. 1981).

    The Opinion can be found at J.A. 1236-43. (Citations herein
    to “J.A. ___” refer to the contents of the Joint Appendix filed by
    the parties in this appeal.)
    3
    Mrs. Kennedy also contends on appeal that the award of
    summary judgment to the defendants resulted from an impermissible
    weighing of the causation evidence, i.e., that the court failed to
    view the evidence in the light most favorable to her, as the
    nonmoving party. For the reasons discussed infra note 14, we need
    not reach this contention.
    2
    I.
    A.
    At approximately 10 a.m. on October 22, 2003, Gregory Kennedy,
    a forty-one-year-old coal miner, was operating a continuous miner
    (the “mining machine”) with a remote control device (the “remote
    controller”) in an underground mining operation in Paramount Coal
    Company’s No. 7 mine, in Dickenson County, Virginia.4      Although Joy
    sold the remote controller under its name as a component of the
    mining machine, Matric had manufactured the remote controller under
    contract with Joy.    The remote controller contained two levers,
    each of which controlled one of the mining machine’s two tracks,
    generally referred to as “trams,” on its right and left sides.        By
    utilizing   the   remote   controller’s   two   levers,   the   operator
    controlled the trams and thus the direction of the mining machine.
    In his work, Mr. Kennedy walked alongside the mining machine during
    its operations and wore the remote controller on a harness strapped
    to his body.
    On the morning of October 22, 2003, Mr. Kennedy was engaged in
    a process called “retreat” mining (also known as “pillaring”), and
    was backing the mining machine out of a cut it had made in a pillar
    4
    The facts underlying this appeal are presented in the light
    most favorable to Mrs. Kennedy, as the nonmoving party with respect
    to the summary judgment motion. See Seabulk Offshore, Ltd. v. Am.
    Home Assur. Co., 
    377 F.3d 408
    , 418 (4th Cir. 2004).
    3
    of coal.5    Mr. Kennedy backed the mining machine through an
    intersection of two mine entries (underground tunnels within a coal
    mine), preparing to make the next cut into the pillar.      At the
    time, two other coal miners, Anthony Blackburn and Willie Mullins,
    were nearby hanging a ventilation curtain, with their backs to Mr.
    Kennedy.    After noticing a change in the sound of the mining
    machine, Blackburn turned and observed that Mr. Kennedy was no
    longer moving.   He immediately illuminated Mr. Kennedy and the
    mining machine with a light, and saw that Kennedy was slumped over
    with blood flowing from his nose and mouth.     Blackburn promptly
    approached Mr. Kennedy and discovered that he was stuck between the
    mining machine and the corner of the coal rib (the wall of the
    mine) around which the machine had been maneuvering. At that time,
    Mr. Kennedy’s back was against the coal rib and the mining machine
    was pressed against his abdomen.     Although the mining machine’s
    left tram was spinning, Blackburn observed that the levers on the
    remote controller were not depressed.
    Blackburn promptly hit the emergency stop button on the remote
    controller, de-energizing the mining machine and stopping the left
    tram from spinning.   While other miners hurriedly sought emergency
    assistance, Blackburn tried to move the mining machine away from
    5
    “Pillar” or “retreat” mining is the process by which a coal
    mining operation works “back from a remote portion of the mine
    toward the entrance and permit[s] the roof to fall in as the
    pillars of coal supporting it [are] removed.” Alsted Coal Co. v.
    Yoke, 
    200 F.2d 766
    , 767 (4th Cir. 1952).

    Mr. Kennedy’s body by using the remote controller.        Although
    Blackburn cut the remote controller from Mr. Kennedy’s body, he was
    unable to get it to function.    Finally, after removing the power
    cord from another unit and attaching it to the remote controller,
    Blackburn was able to move the machine away from Mr. Kennedy’s
    body.   Mr. Kennedy was then airlifted to the emergency room of St.
    Mary’s Hospital in Norton, Virginia, where he was declared dead at
    10:55 a.m.
    The state agency responsible for mine safety in Virginia, the
    Commonwealth’s Department of Mines, Minerals, and Energy (“DMME”),
    was notified of Mr. Kennedy’s fatal accident within twenty minutes.
    A few minutes later, MSHA also received such notification, and
    representatives of both agencies arrived at the coal mine about
    mid-day to begin a joint investigation.     The MSHA investigatory
    team included an electrical engineer, a mining engineer, a mine
    inspection supervisor, and a mine safety and health inspector. The
    MSHA team, working with DMME, collected relevant information,
    questioned company personnel, and examined and photographed the
    accident scene, beginning their work within two or three hours of
    the accident.   The investigation proceeded thereafter over several
    months with an expanded investigative team, including, inter alia,
    the district manager and assistant district manager of MSHA’s
    regional office. From this effort, the MSHA team developed precise
    drawings of the accident scene.      The team conducted extensive
    5
    interviews with those having knowledge of the accident and tested
    the mining machine to assess whether it had been functioning
    properly at the time of the fatality.          It also tested the remote
    controller, along with its various power sources and components, in
    a laboratory setting.
    MSHA’s investigative efforts culminated in its detailed MSHA
    Report,   which   fully   described   the    accident   investigation   and
    included appendices on MSHA’s examination and testing of the mining
    machine and remote controller.            After describing Mr. Kennedy’s
    activities prior to the accident, the MSHA Report detailed the
    tragic event, including the following:
    Kennedy was located close to the inby, left corner of the
    outby block when the machine pivoted to the right. He
    was crushed between the machine’s motor compartment of
    the ripper head and the coal rib. He was standing with
    his back against the coal rib and the machine against his
    abdomen. The bottom of the remote controller was against
    the right portion of Kennedy’s abdomen. The controls of
    the remote controller were not depressed by any means.
    Neither his hands nor any other objects were on the
    controls. The left side track on the machine was still
    spinning in the forward direction.
    J.A. 627.     The MSHA Report observed that there were no eye
    witnesses to the accident, “[n]o one stated the continuous mining
    machine would make unexpected movements prior to the accident,” and
    “[n]o one stated Kennedy had been previously observed within the
    turning radius of the machine.”           Id. at 630.    Importantly, the
    “Overview” section of the Report concluded that:
    The most likely explanation for this continued operation
    is a build up of debris in the left side track operating
    6
    lever’s socket, located on the remote controller, which
    prevented the lever from returning to its neutral
    position.
    Id. at 623.    The MSHA Report listed “causal factors” in its “Root
    Cause Analysis” section, concluding that the “primary cause was the
    victim’s position within the turning radius of the continuous
    mining machine while it was being trammed.”               Id. at 632.        The
    Report also specified another “causal factor,” concluding that
    “[t]he remote control transmitter could have caused the left tram
    drive to continue after the machine operator released the tram
    lever due to debris lodged between the tram lever and the plate.”
    Id. at 633. In its “Conclusion” section, the Report determined, in
    language similar to that used in its Overview, that:
    The left side track of the machine apparently continued
    to move due to a fouled tram lever on the remote
    controller.   Debris accumulated in the lever’s socket
    prevented the lever from returning to its neutral
    position.
    Id.   In its Appendix C, the MSHA Report indicated that “the socket
    for   the   left   tram   lever   was    nearly   full   of   dust   and   dirt,
    restricting its free travel.”           Id. at 639.6
    6
    The Report also related that the MSHA investigation team had
    learned of a subsequent incident that occurred six months after Mr.
    Kennedy’s fatal accident. In that incident, the left side tram of
    the same mining machine continued to operate after both tram levers
    on a replacement remote controller had been released, causing the
    machine to slew to the right.
    7
    B.
    On July 7, 2005, Mrs. Kennedy, for her husband’s estate, filed
    suit against the defendants in the Western District of Virginia,
    asserting that his death was caused by a defective mining machine
    and its associated defective remote controller. Specifically, Mrs.
    Kennedy alleged two negligence claims plus a products liability
    claim, contending that the defendants had negligently designed the
    mining machine and remote controller and negligently failed to warn
    of their dangers.      In her products liability claim, Mrs. Kennedy
    contended that the defendants had breached implied warranties of
    merchantability and fitness for a particular purpose because the
    mining machine and remote controller were defectively designed,
    manufactured, and marketed.         These allegations are spelled out in
    the Amended Complaint filed by Mrs. Kennedy on September 29, 2005,
    which sought both compensatory and punitive damages. On August 11,
    2006, Mrs. Kennedy abandoned her negligence claims.
    On    September   5,   2006,    the   defendants   moved   for   summary
    judgment on the products liability claim, asserting that Mrs.
    Kennedy was unable to prove that their products were defective.
    Defendant Matric also contended that Mrs. Kennedy could not prove
    that any defect in its remote controller caused the death of Mr.
    Kennedy.    In support of their contentions, the defendants argued
    alternate causes of the fatal accident, through expert testimony
    and other evidence — first, that Mr. Kennedy had committed user
    8
    error, based in part on his alleged position within the “red zone,”
    or turning radius of the mining machine, at the time of the
    accident; and, second, that Paramount Coal had made unauthorized
    alterations to the remote controller that allowed excessive dust
    and debris to accumulate in its tram levers.
    When they sought summary judgment, the defendants also moved
    to exclude the evidence of Mrs. Kennedy’s expert witnesses, Dr.
    Thomas Butler and Dr. Farhad Booeshaghi.                        In response to the
    exclusion motion, Mrs. Kennedy withdrew Dr. Booeshaghi as an
    expert,    but    opposed        the   motion    to    exclude       Dr.    Butler.    In
    opposition      to   the    defendants’       summary        judgment      and   exclusion
    motions, Mrs. Kennedy filed, inter alia, the expert report and
    testimony of Dr. Butler, the MSHA Report, and various documents
    illustrating      the    problems      that     defendant      Joy    had    experienced
    earlier with debris accumulation in its remote controllers and the
    resulting unplanned movements of its mining machines.7
    The district court conducted a motions hearing on October 4,
    2006,    and    issued     its    Opinion     the     next    day,   granting     summary
    judgment to the defendants and excluding the opinions of Dr.
    Butler.        By its Opinion, the court concluded that “[a]fter a
    7
    At the request of MSHA, and after receiving complaints that
    remote controllers were sticking because of debris, Joy made a
    series of design revisions to its remote controllers.          In
    connection with a recall of its remote controllers — necessary to
    install the mandated revisions — Joy warned its customers to
    “[p]lease remember that unplanned machine movement may also occur
    due to sticking or damaged switches.” J.A. 974.
    9
    careful review of the summary judgment record, . . . the plaintiff
    is unable to prove causation in this case, an essential element of
    her claim of breach of warranty.”     Opinion 5.    The court went on to
    relate that,
    [w]hile it is certainly possible that this tragic
    accident was caused by the excessive accumulation of coal
    fines and debris in the control sockets, the evidence is
    equally strong that the unplanned movement of the left-
    hand tram resulted from other causes — for example, an
    electronic malfunction (as suggested by one of the
    plaintiff’s former experts) or an inadvertent error on
    the operator’s part (as suggested by a defense expert).
    Id. After observing that, in a products liability action, proof of
    causation must ordinarily be supported by expert testimony, the
    court considered the issue of whether the opinions of Dr. Butler
    were admissible.   Id.   In so doing, the court recognized that Dr.
    Butler had “opine[d] in his report that the accident was caused by
    accumulated debris in a tram control lever socket,” but noted that
    Dr. Butler “did no testing,” failed to “perform[] any calculations
    regarding the accident and admitted that there could be alternative
    explanations,” and that his testimony relied primarily on the MSHA
    Report.   Accordingly, the court granted the defendants’ “motion to
    exclude Butler’s testimony on this point.”         Id. at 6.8
    8
    It is unclear whether the court excluded all of Dr. Butler’s
    opinions, or only his conclusion that the accident was caused by
    accumulated debris in the remote controller’s lever socket. For
    the purposes of our analysis, we assume that all of Dr. Butler’s
    proposed opinions were excluded.
    10
    The district court — acting sua sponte9 — then determined
    that “the MSHA report’s opinion that ‘the most likely explanation’
    for the accident is debris in the lever socket of the 3-X remote
    [controller] is likewise entirely speculative and thus inadmissible
    under     [Federal   Rule   of   Evidence]   803(8)(C).”    Id.   at    7.10
    Accordingly, the court concluded that “the plaintiff is unable to
    prove an essential element of her case — causation — and thus her
    suit must fail.”      Id.    In so ruling, the court pointed out that
    defendant Joy “did not directly assert insufficient causation
    evidence as a ground” for summary judgment, but that defendant
    Matric had argued this proposition.          The court thus observed that
    its ruling would not come as a surprise to Mrs. Kennedy.          Id.
    9
    The district court raised the issue of admissibility of the
    MSHA Report at the motions hearing, asking Mrs. Kennedy’s counsel,
    “does the plaintiff contend that the MSHA report, including its
    finding that you read to me, is admissible?” J.A. 1232. After
    Mrs. Kennedy’s counsel responded in the affirmative, the court
    asked the defendants for their position. Not having previously
    raised an issue concerning the admissibility of the Report, the
    defendants simply responded that, if the court intended to admit
    the conclusions of the MSHA Report, they must meet evidentiary
    standards of reliability. From this record, it is clear that the
    defendants had not contemplated the possibility that the MSHA
    Report’s conclusions might be deemed inadmissible.
    10
    The Opinion seems to indicate that only the “MSHA report’s
    opinion” — as opposed to the entire Report — was excluded.
    Opinion 7. Because the parties share this understanding, we assume
    that the district court considered the MSHA Report, save the
    Report’s conclusion in its “Overview” section, that the “most
    likely explanation for this continued operation is a build up of
    debris in the left side track operating lever’s socket.” J.A. 623.
    11
    Two weeks later, on October 20, 2006, Mrs. Kennedy sought
    relief under Federal Rule of Civil Procedure 59(e), requesting the
    district court to reconsider its summary judgment award to the
    defendants on the products liability claim.             The court denied
    reconsideration on November 13, 2006, and Mrs. Kennedy filed her
    notice of appeal on December 12, 2006.          We possess jurisdiction
    pursuant to 
    28 U.S.C. § 1291
    .
    II.
    We   review   de   novo   a   district   court’s   award   of   summary
    judgment, viewing the facts and all inferences drawn properly
    therefrom in the light most favorable to the nonmoving party.
    Seabulk Offshore, Ltd. v. Am. Home Assur. Co., 
    377 F.3d 408
    , 418
    (4th Cir. 2004).    An award of summary judgment is appropriate only
    “if the pleadings, depositions, answers to interrogatories, and
    admissions on file, together with the affidavits, if any, show that
    there is no genuine issue as to any material fact and that the
    moving party is entitled to a judgment as a matter of law.”            Fed.
    R. Civ. P. 56(c).       A genuine issue of material fact is one “that
    might affect the outcome of the suit under the governing law.”
    Anderson v. Liberty Lobby, Inc., 
    477 U.S. 242
    , 248 (1986).               In
    opposing a summary judgment motion, the nonmoving party is entitled
    to have the “credibility of his evidence as forecast assumed, his
    version of all that is in dispute accepted, [and] all internal
    12
    conflicts in it resolved favorably to him.” Charbonnages de France
    v. Smith, 
    597 F.2d 406
    , 414 (4th Cir. 1979).                          In assessing a
    summary judgment motion, a court is entitled to consider only the
    evidence that would be admissible at trial.                 See Maryland Highways
    Contractors Ass’n, Inc. v. State of Maryland, 
    933 F.2d 1246
    , 1251
    (4th    Cir.    1991)    (noting     that       “hearsay     evidence,     which     is
    inadmissible at trial, cannot be considered on a motion for summary
    judgment”).
    A district court possesses broad latitude in ruling on the
    admissibility of evidence, including expert opinions, and we are
    unable to overturn evidentiary rulings with respect to relevance
    and reliability absent a finding that the presiding court abused
    its discretion.       See GE v. Joiner, 
    522 U.S. 136
    , 141-42 (1997).                  A
    district court has abused its discretion if its evidentiary ruling
    was guided by erroneous legal principles, or rested upon a clearly
    erroneous factual finding.          See Westberry v. Gislaved Gummi, A.B.,
    
    178 F.3d 257
    , 261 (4th Cir. 1999).
    III.
    A.
    In considering this appeal, we first assess Mrs. Kennedy’s
    contention     that     the   district    court     abused      its    discretion    in
    excluding      the   MSHA     Report’s   conclusion        on   the    cause   of   her
    husband’s fatal accident, as being “entirely speculative and thus
    13
    inadmissible under [Federal Rule of Evidence] 803(8)(C).”   Opinion
    7.   As noted, a team of MSHA officials and investigators arrived on
    the accident scene shortly after it occurred on October 22, 2003.
    The MSHA team, comprised of engineers, safety inspectors, and other
    experts, worked jointly with the DMME to secure the relevant
    information, question witnesses, and examine and photograph the
    accident scene, beginning their effort within a few hours of the
    accident. During the investigation, MSHA tested the mining machine
    and remote controller, seeking to ascertain whether they had been
    functioning properly at the time of the fatality.
    When the MSHA Report was finalized, its “Overview” section
    concluded that:
    The most likely explanation for this continued operation
    is a build up of debris in the left side track operating
    lever’s socket, located on the remote controller, which
    prevented the lever from returning to its neutral
    position.
    J.A. 623.    In its summary judgment ruling, however, the Opinion
    determined that “the MSHA report’s opinion that ‘the most likely
    explanation’ for the accident is debris in the lever socket of the
    3-X remote [controller] is likewise entirely speculative and thus
    inadmissible under Rule 803(8)(C).”      Opinion 7.    Mrs. Kennedy
    challenges this adverse admissibility determination, contending
    that consideration of this aspect of the MSHA Report is proper with
    respect to the summary judgment issue, and that such consideration
    will compel the denial of summary judgment to the defendants.
    14
    Mrs. Kennedy’s appellate contention on the admissibility of
    the MSHA Report’s conclusion implicates the provisions of Federal
    Rule of Evidence 803(8)(C).       That hearsay exception specifically
    addresses the use in evidence of “factual findings resulting from
    an investigation made pursuant to authority granted by law.”         Fed.
    R. Evid. 803(8)(C).11    It specifies that:
    The following are not excluded by the hearsay rule, even
    though the declarant is available as a witness . . . (8)
    . . . Records, reports, statements, or data compilations,
    in any form, of public offices or agencies, setting forth
    . . . (C) [when used] in civil actions and proceedings .
    . . factual findings resulting from an investigation made
    pursuant to authority granted by law, unless the sources
    of information or other circumstances indicate lack of
    trustworthiness.
    
    Id.
    Under Rule 803(8)(C), the evidentiary admissibility of public
    records and reports is deemed to be presumed, based on the policy
    determination that such admissibility is warranted “because of the
    reliability   of   the   public   agencies    usually   conducting   the
    investigation, and their lack of motive for conducting the studies
    other than to inform the public fairly and adequately.”        Ellis v.
    Int’l Playtex, Inc., 
    745 F.2d 292
    , 300 (4th Cir. 1984) (internal

    MSHA’s investigation and Report on Mr. Kennedy’s fatal
    accident were made pursuant to authority granted by law. See 
    30 U.S.C. § 813
    (a) (requiring authorized representatives of Secretary
    of Labor (MSHA) to make frequent inspections and investigations of
    mines to determine, inter alia, causes of accidents); 
    30 C.F.R. § 50.1
     (describing MSHA’s authority to “investigate, and to obtain
    and utilize information pertaining to, accidents, injuries, and
    illnesses occurring or originating in mines”).
    15
    quotation marks omitted).             As the Supreme Court has recognized,
    “portions of investigatory reports otherwise admissible under Rule
    803(8)(C)       are    not   inadmissible       merely    because   they      state    a
    conclusion or opinion.”           Beech Aircraft Corp. v. Rainey, 
    488 U.S. 153
    , 170 (1988). When the trustworthiness of such an investigative
    report has been challenged, a court should assess and weigh factors
    such as:       (1) the timeliness of the investigation; (2) the special
    skill or experience of the investigators; and (3) any possible
    motivation problems.            Ellis, 
    745 F.2d at 300-01
    .           We have also
    identified other factors that may, in the proper circumstances, be
    appropriate       to     such    an    evidentiary        assessment,        including
    “unreliability, inadequate investigation, inadequate foundation for
    conclusions, [and] invasion of the jury’s province.” Distaff, Inc.
    v. Springfield Contracting Corp., 
    984 F.2d 108
    , 111 (4th Cir.
    1993).
    In light of the foregoing, the district court necessarily
    abused its discretion in excluding the MSHA Report’s conclusion
    from its summary judgment assessment.                    First and foremost, the
    court failed to recognize and apply a presumption of admissibility
    to the MSHA Report.          As we recognized in Zeus Enterprises, Inc. v.
    Alphin Aircraft, Inc.,“[t]he admissibility of a public record
    specified in the rule is assumed as a matter of course, unless
    there    are    sufficient      negative    factors      to   indicate   a    lack    of
    trustworthiness.”            
    190 F.3d 238
    , 241 (4th Cir. 1999) (internal
    16
    citations omitted).            Furthermore, the party opposing the admission
    of    such   a        report    bears    the      burden     of    establishing         its
    unreliability.         Ellis, 
    745 F.2d at 301
    .            Thus, Rule 803(8)(C) “is
    not a rule of exclusion, but rather is a rule of admissibility,” so
    long as the proffered report satisfies the requirements of the
    rule.    Zeus, 
    190 F.3d at 241
    .
    In this situation, the district court excluded the MSHA
    Report’s conclusion from its summary judgment assessment without
    identifying or explaining any “negative factors [that] indicate a
    lack of trustworthiness,” sufficient to overcome the presumption of
    admissibility.         
    Id. at 241
    .      Although the court observed that the
    Report’s conclusion was speculative, it failed to identify any
    deficiencies in the MSHA investigation or in MSHA’s testing on the
    mining    machine       and    remote   controller.         As    the   Supreme    Court
    recognized       in    Beech    Aircraft,      if   an    investigatory        report    is
    otherwise admissible under Rule 803(8)(C), portions of that report
    are   not    rendered         inadmissible       simply    because      they    state    a
    conclusion or opinion.            
    488 U.S. at 170
    .         Accordingly, the rule of
    presumptive admissibility created by Rule 803(8)(C) was applicable
    to both the data and the conclusions spelled out in the MSHA
    Report.
    Moreover, the district court failed to assess the reliability
    of the MSHA report’s conclusion by use of the various factors
    recognized by our precedent. And, these factors plainly weighed in
    17
    favor of the admissibility of the Report, i.e., — MSHA had
    investigated the fatal accident over several months, beginning
    immediately after it occurred; the MSHA investigators possessed
    special    skills    and    experience;        and    the   defendants     have    not
    suggested    any    “motivational    problems”         relating      to   either   the
    investigation       or    the   Report.         Ellis,      
    745 F.2d at 300-01
    (determining       that     court    should          assess       admissibility     of
    investigatory report by examining timeliness of investigation,
    special skill or experience of officials, and possible motivation
    problems).
    Mrs. Kennedy also emphasizes on appeal that the court should
    not have ruled sua sponte on the admissibility of the MSHA Report’s
    conclusion.      She argues that, despite extensive briefing on the
    summary judgment issues, the defendants had never challenged the
    admissibility of the Report.         As a result, Mrs. Kennedy relied on
    the   Report’s      unchallenged    and        unassailed     contents     as    being
    admissible in their entirety, and she contends that the Report was
    central to her opposition to the defendants’ summary judgment
    request.12    Although a trial court possesses broad discretion in
    12
    On appeal, the defendants now seek to raise issues on the
    trustworthiness of the MSHA Report.    Specifically, they contend
    that the Report was “rife with contradictions.” Br. of Appellees
    46. Their contention in this regard is premised on the fact that
    portions of the Report conclude that a stuck switch could have
    caused the accident, whereas other portions are more certain of
    this result.    The defendants now argue that the Report is
    unreliable because it does not indicate whether the investigators
    were qualified or whether they ruled out operator error as a
    18
    addressing evidentiary issues in any pending case, the defendants
    bore the burden of proof on this issue, and they raised no
    “negative factors to indicate a lack of trustworthiness” of the
    Report.   Zeus, 
    190 F.3d at 241
    ; see also Ellis, 
    745 F.2d at 301
    (concluding that “burden is on the party opposing admission to
    demonstrate that the report is not reliable” and determining that
    this is so because “it is far more equitable to place that burden
    on the party seeking to demonstrate why a time tested and carefully
    considered presumption is not appropriate”).
    In these circumstances, the district court erred, as a matter
    of law, in failing to accord a presumption of admissibility to the
    conclusions of the MSHA Report.   It also erred in failing to apply
    the various factors recognized by our precedent for assessing the
    reliability of such a report, and in presumably placing the burden
    on Mrs. Kennedy to establish that the Report’s conclusions were
    admissible — rather than on the moving defendants to show they
    were inadmissible.   Accordingly, the district court abused its
    discretion in excluding the MSHA Report’s conclusion from its
    possible cause, and because the Report conflicts with the DMME’s
    conclusion. The defendants, of course, should have presented these
    contentions in the district court, rather than in this appeal.

    summary judgment consideration.13    We thus reverse the court’s
    ruling as to the MSHA Report’s conclusion.14
    B.
    Finally, Mrs. Kennedy asserts that the district court erred in
    excluding her proffered expert, Dr. Thomas Butler.     According to
    Mrs. Kennedy, the court abused its discretion when it excluded Dr.
    Butler’s opinions, premised on its determination that Butler had
    failed to perform any independent testing, and relied solely on the
    MSHA Report.   The defendants, in contrast, contend that Butler’s
    qualifications were highly questionable and that he based his
    opinion on a single line in the MSHA report’s “Overview.”     After
    acknowledging that Dr. Butler had opined that the accident was
    caused by accumulated debris in a tram control lever socket, the
    13
    We note that evidence otherwise admissible under Rule
    803(8)(C)   remains   subject  to   other   pertinent  evidentiary
    limitations, such as those in Rules 402 and 403. See Fed. R. Evid.
    402 (providing for exclusion of evidence which is not relevant);
    Fed. R. Evid. 403 (providing for exclusion of relevant evidence if
    probative value is outweighed by danger of unfair prejudice,
    confusion, or delay).
    14
    In light of our disposition of the MSHA Report issue, we need
    not address Mrs. Kennedy’s contention that the district court
    erroneously awarded summary judgment to the defendants after
    weighing the evidence on causation and determining that it was
    “equally strong” on both sides.       Opinion 5.    On remand, the
    evidence of causation should be revisited and include the MSHA
    Report’s conclusion.     We note, however, our concern with the
    apparent consideration of material initially presented by Mrs.
    Kennedy’s withdrawn expert witness, and observe that she is
    entitled to have her evidence viewed in the proper light. See,
    e.g., Charbonnages de France v. Smith, 
    597 F.2d 406
    , 414 (4th Cir.
    1979).
    20
    court determined that “Dr. Butler’s deposition, part of the summary
    judgment     record,    clearly   shows   that   this    opinion   is     mere
    supposition on his part, based primarily on his reading of the
    report of the investigation of the accident by [MSHA].” Opinion 6.
    Because “Dr. Butler did no testing nor performed any calculations
    regarding the accident and admitted that there could be alternative
    explanations for the accident that were beyond his expertise,” the
    court excluded Dr. Butler’s testimony “on this point.”             
    Id.
    We review a district court’s exclusion of expert testimony for
    abuse of discretion, and we do “not overturn Daubert evidentiary
    rulings with respect to relevance and reliability absent an abuse
    of discretion.”        Bryte v. Am. Household, Inc., 
    429 F.3d 469
    , 475
    (4th Cir. 2005) (citing Daubert v. Merrell Dow Pharms., Inc., 
    509 U.S. 579
     (1993)).         A district court is afforded “considerable
    leeway in deciding in a particular case how to go about determining
    whether particular expert testimony is reliable.”            Kumho Tire Co.
    v. Carmichael, 
    526 U.S. 137
    , 152 (1999).          The rules of evidence
    provide that “[i]f scientific, technical, or other specialized
    knowledge will assist the trier of fact to understand the evidence
    or to determine a fact in issue, a witness qualified as an expert
    by   knowledge,   skill,    experience,   training,     or   education,   may
    testify thereto in the form of an opinion or otherwise.”            Fed. R.
    Evid. 702.    And, as the Supreme Court has explained, “[t]he trial
    judge must ensure that any and all scientific testimony or evidence
    21
    admitted is not only relevant, but reliable.” Daubert, 
    509 U.S. at 589
    .
    Dr. Butler’s report indicates that he was “asked to review the
    available documents and other materials and to determine, if
    possible, the cause of the accident.”       J.A. 795.    The documents and
    materials that Dr. Butler reviewed in the preparation of his report
    included: the complaint, answer, and certain other pleadings;
    photographs and videotapes of the scene of the accident; the DMME
    report, the MSHA Report and data; audio cassettes of interviews
    with those who witnessed relevant events on October 22, 2003;
    documents produced by Joy; and deposition testimony.           Although Dr.
    Butler’s report provides a helpful summary of the deposition
    testimony, the MSHA Report, and the documents produced by Joy, it
    does not do so with any specific scientific gloss or expertise.
    Furthermore, most of the conclusions of his report were apparently
    adopted from the MSHA Report.
    The Supreme Court’s decisions in Daubert and Kumho Tire, read
    together, mandate the trial courts to serve as gatekeepers on
    expert   evidence,   and   to   “ensure   that   any   and   all   scientific
    testimony or evidence admitted is not only relevant, but reliable.”
    Daubert, 
    509 U.S. at 589
    ; see also Kumho Tire, 
    526 U.S. at 152
    .            In
    this case, Dr. Butler’s report does not demonstrate any particular
    scientific expertise that can be assessed for reliability or that
    would ultimately assist the finder of fact.             The Report merely
    22
    summarizes   the   evidence   of     record,   without   providing   any
    specialized analysis to support its conclusions.
    In according the district court the deference to which its
    challenged ruling is entitled, we are therefore unable to disturb
    its exclusion of Dr. Butler’s opinions. We thus affirm that aspect
    of this appeal, but authorize the court to revisit it on remand —
    if it sees fit so to do — in light of this opinion.
    IV.
    Pursuant to the foregoing, we affirm the district court’s
    ruling on the expert witness, reverse its ruling on the MSHA
    Report, vacate the summary judgment award, and remand for such
    further proceedings as may be appropriate.
