Accident · substantial damage
May 21, 2006 · West Glacier, MT
The pilot's failure to attain sufficient airspeed for flight, his attempt to abort the takeoff, and the airplane's subsequent departure off the end of the runway. Contributing factors were the impacted fence and vegetation, and his total lack of experience in type of operation.
These match the airframe or engine model. Whether each one applies, and whether it's been complied with, depends on serial numbers, equipment and logbook entries. Applicability must be confirmed by a mechanic against the aircraft's records.
