What happened
The accident occurred during the takeoff phase of flight under visual flight rules (VFR) conditions. Shortly after departure, the aircraft experienced an in-flight loss of control. This loss of control led to an uncontrolled descent and a subsequent collision with terrain. The impact resulted in the destruction of the airplane by post-crash fire.
The investigation
Examination of the aircraft revealed that the pilot, who also served as the mechanic, had reversed the aileron control cables on the lower aileron sprocket during installation. This mechanical error directly compromised the flight controls necessary for maintaining directional stability and attitude during the critical takeoff phase.
Findings
The primary factor contributing to the accident was the incorrect installation of the aileron control cables by the pilot/mechanic. The reversal of these cables prevented proper aileron response, leading to the loss of control. The aircraft was destroyed by fire following the terrain collision. The sole occupant, identified as the pilot/mechanic, sustained serious thermal injuries in the incident.
Safety message
This incident highlights the critical importance of precise adherence to maintenance procedures and control cable routing specifications when performing aviation repairs. Errors in flight control system installation can have immediate and catastrophic consequences during flight operations.
