What happened
The pilot had completed one normal takeoff and landing prior to the incident. Seeking to practice or demonstrate a short field takeoff procedure, the pilot elected to perform another such maneuver. During the ground roll phase of this takeoff, the pilot held the brakes firmly while applying full throttle to the engine.
While maintaining pressure on the pedals, the pilot's right foot slipped off the right brake pedal. This loss of braking pressure on that side caused the aircraft to yaw sharply to the left. As the aircraft turned abruptly during the acceleration phase, the weight transfer and aerodynamic forces caused the airplane to lift its right wing. The aircraft eventually settled back onto the ground with substantial damage sustained to the airframe.
The investigation
The physical examination of the wreckage revealed substantial damage consistent with the aircraft tipping onto its right side during a high-speed ground maneuver. No mechanical failures of the flight controls or engine were identified that would have contributed to the event. The investigation focused on the pilot's actions during the takeoff roll and the resulting loss of directional control.
Findings
The primary factor in this accident was the pilot's inability to maintain directional control due to a slip of the foot from the brake pedal. This error occurred during a critical phase of flight where precise rudder and brake coordination is essential, particularly when operating at high power settings with brakes applied. The sharp turn generated excessive loads on the landing gear and wing structure, leading to the substantial damage observed.
Safety message
Pilots should ensure proper foot placement and secure footing before applying full throttle during takeoff rolls. When performing short field takeoffs that require brake holding, it is critical to maintain consistent pressure on both pedals until sufficient airspeed is achieved for rudder effectiveness. Practicing emergency procedures in a safe environment can help prevent loss of control during high-power ground operations.
