What happened
The private pilot was preparing for takeoff on runway 18 when he initially observed winds coming from the southwest. As the aircraft began its takeoff roll and lifted off, the wind conditions changed significantly. Witnesses reported that the wind shifted direction during the attempt, becoming strong from the north.
This sudden change in wind direction and strength caused the airplane to lose lift and settle back onto the runway surface. Unable to regain sufficient airspeed or altitude, the aircraft continued down the remaining pavement. It eventually overran the end of the runway, striking a haystack located near the threshold. The impact with the haystack caused the aircraft to nose over.
The investigation
Investigation of the incident focused on the environmental conditions at the time of the accident. Witnesses confirmed that the wind shifted from southwest to strong north during the critical phase of takeoff. This shift likely resulted in a rapid loss of airspeed and lift, preventing the pilot from completing the takeoff safely.
Findings
The primary factor contributing to this accident was the wind shift during takeoff. The transition from a tailwind or crosswind component to a strong headwind or different crosswind component disrupted the aircraft's performance. This environmental condition led directly to the runway overrun and subsequent collision with the haystack.
Safety message
Pilots must remain vigilant for changing wind conditions during takeoff, especially in areas prone to rapid weather shifts. Understanding how wind direction affects lift and airspeed is critical for safe departure operations.
