What happened
During a flight test for a private pilot certificate, the aircraft experienced a critical failure to achieve necessary climb performance. The prospective pilot was unable to gain sufficient airspeed on takeoff to enable the aircraft to climb effectively. Approximately three-quarters of the way down the runway, the check pilot made the decision to abort the takeoff and pulled the power off. Consequently, the aircraft collided with trees located off the departure end of the runway.
The investigation
The primary focus of the examination was the takeoff performance and the subsequent abort decision. The factual narrative indicates that the aircraft did not accelerate adequately during the ground roll. The check pilot's intervention involved cutting power to prevent a potential overrun or stall, but the aircraft lacked the altitude or speed to clear the obstacles at the end of the runway.
Findings
The critical factor in this accident was the failure to gain sufficient airspeed. The prospective pilot did not achieve the necessary performance parameters for a safe departure. The check pilot's decision to abort was based on the lack of climb capability, but the timing and speed resulted in an impact with terrain. The aircraft collided with trees off the departure end of the runway.
Safety message
Pilots must ensure adequate airspeed is achieved during takeoff to enable climbing performance. Failure to gain sufficient speed can lead to a loss of control or collision with obstacles at the end of the runway. Check pilots should monitor acceleration closely and be prepared to abort if performance targets are not met.
