This accident data was analyzed by the Joint Helicopter Safety Analysis Team, a sub-committee of the IHST. The IHST was formed in 2005 to lead a government and industry cooperative effort to address factors that were affecting an unacceptable helicopter accident rate. The group’s mission is to reduce the international civil helicopter accident rate by 80 percent by 2016. From 2006 to 2011, the analysis team completed an analytical review of three years of U.S. helicopter accident data from 523 different accidents.
