  1. Army aeromedical crash rates.

    Article - En anglais


    Safety is a principal concern for everyone in aviation, including those in military and civilian aeromedical programs.

    The U.S. Army flies thousands of helicopter missions each year, including many aeromedical flights.

    The comparison between Army general and aeromedical aviation crash data provides a benchmark for establishing patterns in aeromedical safety and may be useful for similar programs examining safety profiles.


    To determine the crash rates of Army aeromedical rotary-wing (helicopter) programs and compare them with crash rates in Army general aviation.


    Retrospective review of safety data from 1987 to 1995.

    Crashes or mishaps are categorized into three classes : A, B, and C. Class A reflects the most serious mishap and involves loss of life or aircraft destruction, whereas classes B and C represent lesser but still significant mishaps.

    Crash rates are compared on a year-by-year basis and are reported as events per 100,000 flight hours.

    Statistical analysis was performed by the z test with Yates'correction, with significance set at p <= 0.05.


    During the study period, 13.31 million total flight hours were recorded, with 741,000 aeromedical hours logged.

    The mean Army general aviation class A crash rate was 1.86 compared with the aeromedical rate of 2.02.

    The mean general class A to C crash rate was 7.37 compared with the aeromedical rate of 7.44. (...)
