Safety record

Accident & incident history

2017-11-25 Accident · Willows, CA Damage: Substantial Minor injury NTSB · WPR18LA036
Reported aircraft: Doshier Wilbert A GT-500 — a different aircraft that carried the N599RA registration before this airframe.
Probable cause: A loss of engine power during takeoff due a coolant leak and the subsequent overheating of the engine, and the student pilot's failure to maintain airspeed and his exceedance of the airplane's critical angle of attack, which resulted in an aerodynamic stall and collision with terrain.  Contributing to the accident was inadequate maintenance inspection and the flight instructors delayed remedial action.
