Rule of Law:
An expert's opinion identifying a manufacturing defect through a process-of-elimination methodology, even without direct physical evidence of the specific flaw, can be admissible under Federal Rule of Evidence 702 and is sufficient to create a genuine issue of material fact to survive summary judgment in a products liability action under the Alabama Extended Manufacturer’s Liability Doctrine (AEMLD).
Facts:
- Douglas Norman Rudd owned a 1970 GM pickup truck.
- While Rudd was in front of the vehicle's open hood advancing the truck's timing, a fan blade on the truck's engine broke loose.
- The separated fan blade was propelled from the engine bay.
- The blade struck Rudd in his head, neck, and left arm, causing serious and permanently disabling injuries.
- An expert examination of the fan revealed no visible damage or bending at the fracture origin that would explain the failure, and concluded Rudd's operation of the truck was normal.
Procedural Posture:
- Douglas Norman Rudd filed a complaint against General Motors Corporation (GM) in the United States District Court for the Middle District of Alabama.
- Rudd's complaint alleged claims under the Alabama Extended Manufacturer’s Liability Doctrine (AEMLD) for a manufacturing defect, failure to warn, and lack of a protective shield, as well as common-law negligence.
- GM moved for summary judgment against Rudd on all claims, arguing Rudd had produced no admissible evidence of a defect.
- For the purpose of its summary judgment motion only, GM assumed that the cooling fan was a GM part.

Issue:
Does an expert's testimony, based on a process-of-elimination methodology to conclude a manufacturing defect exists, satisfy the reliability requirements of Federal Rule of Evidence 702 and create a genuine issue of material fact sufficient to survive summary judgment on a products liability claim?
Opinions:
Majority - Myron H. Thompson
Yes. An expert's opinion based on a process-of-elimination methodology is admissible under Federal Rule of Evidence 702 and can be sufficient to defeat summary judgment. The court applied the recently amended Rule 702, which requires expert testimony to be based upon 1) sufficient facts or data, 2) reliable principles and methods, and 3) a reliable application of those principles and methods. The court found that the plaintiff's expert, Edmondson, satisfied this standard by systematically considering and ruling out alternative causes for the fan's metal fatigue failure (such as misuse or operational damage). Although Edmondson could not identify a specific microscopic flaw, his reliance on circumstantial evidence and elimination of other possibilities was a reliable method used in failure analysis, supported by professional literature. Under the Alabama Extended Manufacturer’s Liability Doctrine (AEMLD), a plaintiff is not required to provide direct proof of a specific defect; a prima facie case can be established by raising a reasonable inference that the injury resulted from the product's defective condition. Because Edmondson's admissible testimony negated other causes, it created a genuine issue of material fact regarding a manufacturing defect, making summary judgment on that claim inappropriate. However, the court granted summary judgment for GM on the failure-to-warn and defective design claims because Rudd presented no evidence to support them.
Analysis:
This decision clarifies how the gatekeeping function under the amended Federal Rule of Evidence 702 applies to 'process-of-elimination' expert testimony in products liability cases. The court establishes that such testimony is not inherently unreliable simply because it lacks direct evidence of a specific defect. This lowers the evidentiary bar for plaintiffs at the summary judgment stage, allowing cases to proceed to a jury based on strong circumstantial evidence and expert analysis that reliably excludes other potential causes of a product's failure. The ruling reinforces the principle that plaintiffs can prove a defect by inference, which is particularly significant in cases where the evidence of the specific flaw is destroyed in the accident or is microscopic in nature.
