While the probability of risk is low with warnings and instructions for the gust lock and airplane checklist, the magnitude of harm is great from the injuries that can result. Furthermore, the proposed alternative design decreases the foreseeable harm caused by the defective gust lock without impacting the utility of the airplane. In addition, using a risk utility balancing with room for expert opinions to assist the triers of fact creates an administrable and understandable standard and evidence for non-expert triers of fact. Therefore, based on the evidence and the restatement, there is a defect with the gust lock and there is a reasonable alternative design in redesigning the gust locks to prevent pilots from advancing the throttles of the airplane beyond low levels when the gust lock is still
