Fatal aviation accident: SCHWEIZER 269C-1 near Boxborough (2010-05-26)
Probable cause: The FAA inspector's rapid reduction of power which resulted in a loss of engine power and his decision to initiate a turn during the autorotation without sufficient altitude to clear obstacles. Contributing to the accident was the FAA’s lack of comprehensive currency requirements in the make and model helicopter and the inspector's specific limited recent flight experience related to this make and model helicopter.
