U.S. Helicopter Safety Team (USHST) Calendar Year Metrics

-Goal:  Reduce the 5 year average fatal accident rate to 0.55 per 100K hours by 2025.  The USHST uses the fatal accident rate from CYs 2014-2018 (0.62 per 100K hours) as their baseline for measurement.

-The CY 2016-2020 5 year average fatal accident rate was 0.68 per 100K hours through June 2020.
