What happened
During a takeoff maneuver, the pilot of the Cessna 150 performed an aggressive maneuver that resulted in an accelerated stall. This led to a loss of control at an altitude that was too low to allow for recovery.
The investigation
The investigation examined the aircraft's condition and found a twisted left wing. This structural issue had reduced the airplane's stall margin. Additionally, the investigation looked into the maintenance practices of the Oahu Parachute Center and its contract mechanic, finding that the aircraft had not been maintained in an airworthy condition and the wing damage had not been detected or repaired.
Findings
Several contributing factors were identified in the accident:
- The pilot's aggressive takeoff maneuver caused an accelerated stall.
- The airplane was operated near its aft center of gravity limit.
- The pilot lacked sufficient training and experience regarding the handling qualities of the aircraft in this specific flight regime.
- The failure of the Oahu Parachute Center and its contract mechanic to maintain the aircraft in an airworthy condition and to repair the twisted left wing.
- An insufficient FAA regulatory framework for overseeing parachute jump operations.
- The FAA's lack of awareness regarding the pilot's instructor providing substandard training.
