The pilot’s exceedance of the airplane’s critical angle of attack while maneuvering at low altitude, which resulted in an aerodynamic stall and subsequent loss of control. Contributing to the accident was the pilot/owner’s improper installation of engine mount hardware during recent maintenance, which resulted in the partial separation of the engine and likely degraded controllability of the airplane.

a loss of engine power for undetermined reasons. A factor related to the accident was the presence of traffic requiring the pilot to perform an evasive maneuver.
