Safety record

Accident & incident history

2021-12-11 Accident · Bedford, NH Damage: Destroyed Fatal injury NTSB · ERA22FA086

Reported aircraft: Swearingen SA226

Probable cause: The pilot s failure to secure and feather the left engine and increase power on the right engine after a perceived loss of engine power in the left engine, which resulted in a loss of control and impact with terrain just short of the runway. Contributing to the accident was a reduction in engine power from the left engine due to a 1st stage turbine blade midspan separation and material loss in the 2nd stage stator that were the result of engine operation at high temperatures for an extended period of time.
