Abstract:

A statistical review is presented of 147 major helicopter fire accidents that occurred during an eight-year period. Ninety percent of fires in major accidents erupt on or immediately after the initial impact of the crash sequence. In 48 of the 106 survivable fire accidents, fuel spillage occurred. Fuel tanks and lines continue to fail and cause spillage. Twenty-seven 57 of the 47 inflight fires for the eight-year period were classified as either precautionary or forced landings. Fourteen inflight fires were present in major accidents. Fires account for 10 of the major accidents and are responsible for 44 of the injured and 72 of the fatalities in all major helicopter accidents. Sixty-six percent of the occupants involved in major fire accidents were injured as compared to 11 in other types of major accidents. Thirty-five percent of the fire-accident occupants received thermal injuries. The occupant survival rate in fire accidents is 64 as compared to 98 for nonfire major accidents. Thirty-five fatalities, 18 in survivable accidents, have been attributed to thermal injuries. The cost of damaged and destroyed helicopters in fire accidents during FY 64-65 totaled eight million dollars. The total for the previous six years was 12 million dollars. Author
