The doctrine of strict liability means that in an aviation accident, the manufacturer may be held liable for injury or damages, even if there was no negligence or intent to commit an offense. Three things must be shown in order to establish strict liability:

• The product must have been defective at the time it left the manufacturer.
• The product must have been used properly and according to its intended function.
• The product must have, in some way, been responsible for the injury or damage resulting from the aviation accident.
