Plaintiff, Mrs. Deborah Taylor, was injured when a tire manufactured by Defendant, Cooper Tire and Rubber Co., failed. At issue in this products liability case applying Utah law was the cause of the tire failure. Plaintiff alleged a manufacturing defect. Defendant asserted a variety of defenses including alternative causes for the tire failure other than a manufacturing defect. The district court held that Plaintiff’s proposed expert witness was not qualified to testify to any alleged defect in the tire and granted Defendant’s Motion in Limine to exclude this testimony. The court then held that Plaintiffs claim could not be sustained absent expert witness testimony that the tire was defective and dismissed the case.
Plaintiff challenges the district court’s ruling, contending that (1) her witness was qualified to testify as an expert about the reason for the tire’s failure; (2) the lack of expert testimony is not fatal to her case; and (3) the court made procedural errors. We affirm the trial court’s decision that the witness was not qualified as an expert pursuant to Federal Rule of Evidence 702, but reject the court’s conclusion that Utah law requires expert testimony to establish a viable cause of action in product liability.
Plaintiff contends that the district court erred in finding that her witness was not qualified to testify as an expert. In the course of Plaintiff’s case, she attempted to proffer the testimony of an expert to support her manufacturing defect theory. The court held a hearing outside the presence of the jury to determine whether the expert was qualified pursuant to Federal Rule of Evidence 702. The evidence at the hearing showed that the witness was qualified generally in materials failure, particularly metals. The central focus of the inquiry, however,
The district courts have broad discretion to determine the admission of expert testimony.
See Compton v. Subaru of Am., Inc.,
THE COURT: [D]id you do some kind of testing on this tire, or did you contemplate it to try to ascertain whether this particular separation of the plies occurred because of the tire’s impact with an object on the road or a curb or some external object?
THE WITNESS: No, I did not do that. No, sir.
THE COURT: But wasn’t your job to express an opinion as to the mode of failure?
THE WITNESS: Yes.
THE COURT: Didn’t you want to check that one out?
THE WITNESS: You mean to find out if it had been hit by some object and something had failed inside the tire?
THE COURT: Yes, and that that led to the failure.
THE WITNESS: I guess at that point I hadn’t — I hadn’t considered that because I didn’t see any kind of damage from the outside, and I guess that is the only thing that I can say right now.
Q And you admitted today in fact that you are not an expert in the manufacturing of tires?
A Correct.
THE COURT: [Your opinion] is still based pretty much on your initial look at the tire and taking some photographs and determining that it looks like this thing separated improperly?
THE WITNESS: Right. You can tell that it was a blowout for sure, but other than that, that is correct.

Our review of the hearing testimony leads us to conclude that the trial court did not abuse its discretion when it found the expert was not sufficiently qualified to testify on the critical issue in this ease.
See Meyerhoff v. Michelin Tire Corp.,
Plaintiff also asserts that the district court erred in dismissing her claim for lack of expert testimony. Immediately after excluding Plaintiffs expert, the court stated that it would entertain a motion to dismiss the case. Defendant moved to dismiss the case, and the court granted this motion. Our review of the record reveals the court believed that to recover for manufacturing defect under Utah law, a plaintiff is required to prove the element of product defect with expert testimony.

On its face the order is one to dismiss as a matter of law for failure
Our reading of Utah law persuades us that no such rule has been established in Utah and that the general trend in the law is that plaintiffs may prove product defect through circumstantial evidence. In
Hooper v. General Motors Corp.,
[A product’s failure], standing as an isolated fact, would be an insufficient factual basis for an inference that the wheel was defective at the time it was assembled____ However, when viewed in relation to other evidentiary facts — ... expert testimony ... the age of the truck; ... the fact that it had no record of prior damage; the description of the mishap by plaintiff ... then the fact of [product failure] may have provided the requisite force to tip the scales in favor of plaintiff. Certainly, reasonable men from the cumulative factual total could infer ... that the wheel was defective at the time of assembly.
Id.
at 551-52. Additionally, in
Hewitt v. General Tire & Rubber Co.,
Utah law requires a plaintiff to prove that “at the time the product was sold by the manufacturer ... there was a defect or defective condition in the product which made the product unreasonably dangerous to the user or consumer.” Utah Code Ann. § 78-15-6(1). One Utah case has dealt with the argument that a manufacturing defect can be supported solely by expert testimony.
See Nay v. General Motors Corp.,
The developing law in other jurisdictions does not suggest an irresistible trend in the other direction which would lead Utah to change its position. It is clear that in many states circumstantial evidence, whether expert or not, may support a manufacturing defect claim.
See, e.g., Orth,
Although the substantive law of Utah applies in a diversity products liability case, federal law controls as to whether there was sufficient evidence to warrant submitting this ease to a jury.
See Orth,
A trial court should determine what constitutes a sufficient amount of circumstantial evidence for a case to go to a jury after the plaintiff has rested her case. Because it appears that this stage of the case had not been reached when the trial court ruled, it is necessary to remand for a new trial. Therefore, we do not decide the procedural errors raised by Plaintiff.
Defendant moved to strike from consideration by this court the affidavits of counsel involved in this case, which were offered by Plaintiff in her Motion to Correct the Record. Because none of the material that Defendant finds objectionable was considered in the disposition of this case, the Motion to Strike is denied.
See Osborne v. Babbitt,
We therefore AFFIRM the district court’s ruling on Plaintiffs expert witness, REVERSE the district court’s grant of the motion for judgment as a matter of law, DENY Defendant’s Motion to Strike, and REMAN'D for further proceedings consistent with this opinion.
AFFIRMED in part, REVERSED in part, and REMANDED.
Notes
. The trial court stated:
I’m going to have to dismiss the case. There is no evidence to support the plaintiff's claim of a manufacturing defect and I’m well aware of that. You have to have a witness that can qualify as having the kind of knowledge that would allow him to express that opinion.

"Plaintiff’s claims of alleged defect of the subject tire cannot be sustained absent expert witness testimony as to said defect.” App. to Appellant's Br., Vol. II at 390 (Order Excluding Expert Witness and Judgment of Dismissal With Prejudice at ¶ 2); see also id. at 387 (Findings of Fact and Conclusions of Law at ¶ 5).
