This paper examines the impact of a strict product liability standard on the accident rate in the general aviation (GA) industry. Liability expenses increased by 775% between 1976 and 1986, reducing the sales of new GA aircraft by 90% and increasing the age of the GA fleet. Using both aggregate and model-specific data, our results indicate that the increase in the age of the GA fleet increased the accident rate by 25%–35% during 1981–2000. In addition, the higher price of GA aircraft boosted sales of homebuilt planes, which have higher accident and fatality rates than GA aircraft. (JEL K13, L62, L15)
