Products Liability Engineering Expert Witness

Products liability engineering expert witnesses evaluate whether product design, manufacturing, warnings, and instructions met applicable safety standards and consumer expectations. They conduct failure analysis, material testing, exemplar inspections, and design alternative assessments to determine whether a defect existed, whether it caused the injury, and whether a feasible safer alternative design was available at the time of manufacture.

Cases commonly requiring products liability engineering expertise include consumer product failures causing injury or death, industrial machinery and equipment accidents, medical device malfunction, automotive component failure, and children's product safety violations. These matters require an expert who can address all three defect theories—design defect, manufacturing defect, and failure to warn—and who understands the engineering trade-offs inherent in product development.

Subspecialty areas including mechanical failure analysis, materials science, consumer product safety, industrial machinery guarding, automotive systems, and medical device engineering each involve different testing standards, regulatory frameworks, and industry design practices. An expert with relevant product development or testing experience provides the engineering credibility necessary to withstand rigorous cross-examination on alternative design feasibility and risk-utility balancing.
