What happened
The airplane collided with the ground after experiencing an aerodynamic stall. The incident occurred while the aircraft was executing a left turn at an altitude of approximately 200 feet above ground level, shortly after initiating takeoff. A critical factor in the accident was that the total weight of the airplane at departure exceeded its certified maximum limit by roughly 100 pounds. Additionally, the aircraft lacked shoulder harnesses for its occupants.
The investigation
Following the impact, investigators conducted a thorough examination of the airframe and propulsion systems to determine if mechanical failure contributed to the loss of control. The inspection of the engine revealed no mechanical anomalies or defects that would have prevented normal operation. The absence of mechanical issues pointed toward operational factors as the primary cause of the stall.
Findings
The investigation identified several contributing elements to the accident sequence. The aircraft was overloaded at takeoff, which likely degraded its climb performance and maneuverability. The pilot attempted a left turn at a low altitude while the airplane was already near its stall speed, exacerbated by the excessive weight. The lack of shoulder harnesses meant that occupants were not restrained during the violent impact with terrain.
Safety message
Pilots must ensure that aircraft weight and balance calculations are strictly within certified limits before every flight. Exceeding maximum takeoff weight can severely compromise climb performance and stall margins, particularly during critical phases of flight such as takeoff and initial climb. Proper planning and adherence to weight restrictions are essential for maintaining control authority.
