What happened
The pilot initiated a soft field takeoff from a grass runway under challenging weather conditions characterized by winds gusting up to 34 knots. Immediately after becoming airborne, the aircraft remained in ground effect without gaining sufficient airspeed or altitude. The pilot determined that the current climb performance was insufficient to clear obstacles in the flight path. In an attempt to maneuver around these hazards, the pilot initiated a turn to the right and simultaneously retracted the flaps. This action caused the aircraft to lose energy rapidly, resulting in a descent and subsequent collision with the terrain.
The investigation
Examination of the event focused on the aerodynamic performance during the critical takeoff phase. The lack of acceleration and climb capability was attributed to the combination of high wind gusts and the decision to retract flaps while turning at low airspeed. The retraction of flaps reduced lift, exacerbating the inability to maintain altitude in ground effect.
Findings
The primary factors contributing to this accident were the high wind conditions and the pilot's decision to retract flaps during a turn at low airspeed. These actions led to a loss of control and collision with terrain. The aircraft was unable to out-climb obstacles due to insufficient climb performance.
Safety message
Pilots should exercise extreme caution when performing soft field takeoffs in high wind conditions. Maintaining appropriate flap settings and avoiding premature configuration changes during the initial climb phase is critical for maintaining control and clearing obstacles.
