What happened
The pilot reported conducting a short field takeoff procedure utilizing one notch of flap extension. Following rotation and initial climb, the aircraft experienced a loss of both airspeed and altitude, causing it to settle back toward the runway environment. As the descent continued, the airplane began drifting to the left side. The aircraft subsequently impacted the ground with simultaneous contact made by the left wing and the tail section.
The investigation
Post-accident review included an analysis of the pilot's account regarding the takeoff performance and flight dynamics. The pilot explicitly stated that he lifted off the runway surface earlier than optimal, resulting in inadequate airspeed to sustain a positive climb gradient. This premature rotation contributed directly to the loss of lift and subsequent ground contact.
Findings
The primary factor in this accident was the pilot's decision to rotate too early during the takeoff roll. By lifting off before achieving adequate airspeed, the aircraft lacked the necessary energy to clear obstacles or maintain a safe climb path. The use of one notch of flaps for a short field takeoff is standard, but the execution of the rotation phase was flawed. The resulting drift to the left and subsequent settling indicate that the angle of attack was likely excessive relative to the available airspeed.
Safety message
Pilots must ensure that rotation speed is achieved before lifting off during short field takeoffs. Premature rotation can lead to a stall or insufficient climb performance, especially when operating near the limits of aircraft performance. Maintaining adequate airspeed is critical for safe flight operations after liftoff.
