Association of Medical Certification Factors with All-Cause Mortality in U.S. Aviators

INTRODUCTION: The value of aeromedical certification in reducing adverse medical outcomes is an especially important question for this era of increasing flight operations that do not require an FAA medical certificate. The study of this question has previously been thwarted by a lack of information about pilots when their medical certificates are not renewed.METHODS: We matched airmen in the FAA medical certification database to the U.S. Social Security Death Index to identify date of death for deceased pilots. Logistic regression models were used to explore associations of certification data with odds of death while holding a medical certificate and within 4 yr of expiration of a medical certificate.RESULTS: FAA aeromedical waivers were associated with 33% lower odds of death while holding a medical certificate and 35% increased odds of death within 4 yr after expiration of a medical certificate. Denial was associated with 21% increased odds of death in the next 4 yr. Only 13 of 47 medical conditions having significant associations were associated with increased odds of death during certification.DISCUSSION: We found that FAA aeromedical certification reduces the odds of death while holding a medical certificate compared to the 4 yr after certificate expiration. We believe this helps provide a positive answer to the question of whether medical certification reduces medically related events.Mills WD, Greenhaw RM.
