OPINION

PER CURIAM:

Sally Edwards (“Mrs.Edwards”), individually and as executrix of the estate of Captain Robert Francis Edwards, and on behalf of her two minor children, brought this wrongful death action in the Northern District of West Virginia against Bell Helicopter Textron, Incorporated (“Bell”). Captain Edwards, an officer in the Marine Corps, was killed in a 1996 helicopter crash in Georgia. The trial jury returned its verdict in favor of Bell, and Mrs. Edwards has appealed, contending that the district court committed reversible error when it excluded certain evidence of Bell’s liability. Because we are unable to say that the court abused its discretion in its resolution of the contested evidentiary issues, we affirm the judgment in favor of Bell.

I.

A.

On March 1,1996, Captain Edwards was killed when the Bell AH-1W helicopter that he flew as a Marine Corps pilot (the “Edwards Helicopter”) crashed near Columbus, Georgia. The crash was caused by the failure in flight of the craft’s “tail rotor yoke” (the “Yoke”). 1 Mrs. Edwards filed this wrongful death action against Bell in the Northern District of West Virginia in February of 1998, asserting multiple theories of liability. 2 Significantly, the parties agree that the Yoke failed from metal fatigue, resulting from an unduly *676 low level of “compressive residual stresses” (“CRS”), 3 which caused the Yoke to separate from the Edwards Helicopter. Although Bell designed and built its tail rotor yokes for a 2200-flight-hour service life, the Yoke failed after only 728 flight hours. In the Joint Pretrial Order, Mrs. Edwards asserted that “[t]he material fact at issue in the litigation is what caused the low level of CRS[ ] that enabled fatigue to set in and destroy the strength of the [Yoke] on [the Edwards Helicopter].”

B.

1.

At trial, the parties offered competing theories on the cause of the Yoke’s fatally low CRS level. According to the evidence, there are several ways for a tail rotor yoke to lose its CRS, including (1) defective shot peening; (2) mishandling; (3) excessive static bending loads; 4 or (4) gradual dynamic relaxation during normal flight. 5

Bell’s theory of defense was that the Yoke’s CRS loss was the fault of the Marine Corps. It contended that the Yoke, used previously on a different helicopter, had experienced a “static bending load” in 1993 when that prior helicopter was acci-dently towed into the blade of a larger aircraft (the “Towing Incident”). Following the Towing Incident, the Yoke was removed from the prior helicopter, visually inspected, and installed on the Edwards Helicopter. In support of its contention that the Towing Incident had caused the Yoke’s CRS loss, Bell relied on the Marine Corps’ investigation of the fatal crash. That investigation found that the Towing Incident had “caused a weakness/problem to develop over time in the [Y]oke.... This weakness/problem in the [Y]oke went undetected and ultimately resulted in the [Y]oke assembly failing/fracturing in flight.” 6

Mrs. Edwards presented competing theories for the cause of the Yoke’s CRS loss, based upon the opinions of her two experts, Drs. Thomas Butler and Oddvar Bendiksen. Dr. Butler testified that the Yoke’s CRS loss was caused by either (1) improper shot peening during manufacture, or (2) mishandling. While Dr. Butler was able neither to identify the more likely of these two possible causes, nor to say whether it was Bell or the Marine Corps that was responsible for any mishandling, he ruled out the Towing Incident as a cause of the fatal crash. Dr. Bendiksen, by contrast, testified that the Yoke’s CRS loss was due to gradual dynamic relaxation. He also testified, consistent with Dr. Butler, that the Towing Incident did not cause the Yoke’s CRS loss.

2.

Prior to trial, Bell moved to exclude from evidence all references to a modifica *677 tion that Bell had made in the design of the tail rotor yokes of its helicopters. This modification was the introduction of a “yielding” version of the craft’s flapping stop, 7 and it resulted from a Bell study conducted following the 1987 crash of a different model of Bell helicopter. In 1992, after the conclusion of the Bell study, the company’s Safety Board noted that two types of Bell helicopters, the 214ST and the AH-1W (both of which used the same tail rotor yoke), were vulnerable to CRS loss from unwitnessed static bending loads, possibly resulting from improper tie-down procedures for the tail rotor assembly. The Safety Board recommended to Bell’s engineering department that it redesign the tail rotor’s “flapping stop” on the 214ST helicopter. The purpose of the redesigned flapping stop was to permit it to bend when a sufficient static bending load was placed on the tail rotor yoke to produce CRS loss. This yielding flapping stop (the “YFS”) was to serve as a “visual cue” to maintenance personnel of an unwit-nessed static bending load. If maintenance personnel discovered a bent YFS, the tail rotor yoke could be promptly tested for CRS loss through a process known as “X-ray diffraction.” 8 The Safety Board’s recommendation for installation of a YFS was limited to the Bell model 214ST helicopter. The Safety Board did not recommend installation of a YFS on Bell’s model AH-1W (the model of the Edwards Helicopter) because it believed that, due to the different flight loads 9 typically placed on that model, “dimensional inspections” 10 would adequately detect whether a tail rotor yoke had experienced an unwit-nessed static bending load that might have caused CRS loss.

Bell first tested the YFS in November of 1993, and in 1994 it obtained approval from the Federal Aviation Administration for YFS installation on its 214ST helicopters. Between 1994 and the fatal crash of the Edwards Helicopter in 1996, two other Bell helicopters crashed due to failed tail rotor yokes. 11 Approximately a month after the March 1, 1996, crash of the Edwards Helicopter, Bell recommended to the Marine Corps that it install the YFS on its AH-1W helicopters.

Bell’s motion sought to exclude from evidence all information pertaining to the YFS (the ‘YFS evidence”). It contended that the YFS evidence was irrelevant to the issues to be considered by the jury. Bell maintained that YFSs are useful only in the detection of unwitnessed static bending loads, and that both of Mrs. Edwards’s experts had opined that a static bending load was not the cause of the Yoke’s CRS loss. As such, the failure to install a YFS on the Edwards Helicopter could not have been related to the fatal crash.
