What happened
The private pilot initiated takeoff with two passengers aboard the aircraft. Shortly after leaving the ground, the airplane failed to climb as expected. The pilot reported hearing a stall warning horn, followed immediately by a drop of the left wing. In response, the pilot reduced engine power and allowed the aircraft to settle onto the ground off the left side of the runway. The plane impacted a field containing steel drums.
The investigation
The investigation focused on the mechanical condition of the aircraft and the sequence of events during the initial climb. Examination revealed that the airplane was unable to generate sufficient lift to sustain flight at the airspeed achieved during takeoff. The stall warning system functioned correctly, alerting the pilot to the loss of airflow over the wings.
Findings
The primary factor in this accident was the failure to maintain adequate airspeed during the critical phase of flight. The aircraft entered a stall condition shortly after liftoff, leading to an uncontrolled descent. The presence of steel drums in the impact area contributed to the extent of damage sustained by the airframe.
Mooney M20C
The pilot's decision to reduce power rather than attempt to recover from the stall likely prevented a more severe crash, but resulted in substantial damage to the aircraft. The incident highlights the importance of maintaining proper takeoff speeds and recognizing early signs of an impending stall.
Safety message
Pilots must ensure that takeoff performance calculations are accurate and that airspeed is maintained throughout the initial climb. Early recognition of stall symptoms is critical for recovery. In this case, stall was the immediate cause of the loss of control.
