Abstract
This study examines the effects of component failures, regulatory actions, and safety violations on stock returns and market volatility in the U.S. aerospace sector. Using FAA incident reports, WRDS market data, and corporate disclosures, the analysis combines event study methodology with ARCH/GARCH volatility models and a multiple regression approach. The results reveal that while incident frequency does not significantly affect stock prices measured by abnormal returns, firm-specific financial indicators—such as cash holdings and book-to-market ratio—play a substantial role. The study highlights the limited explanatory power of traditional regression models and calls for the inclusion of market risk and investor sentiment factors. These insights are particularly valuable for investors, regulators, and strategists navigating risks in the aerospace industry.
