Pilot admits improper installation caused control stick to detach during takeoff (N1984A)

What happened

The incident occurred during the initial climb phase of flight immediately following takeoff. According to the pilot's account, the aircraft reached an altitude of approximately 40 feet above ground level when the control stick suddenly detached from its mounting point. Upon realizing the loss of control, the pilot reduced engine power in an attempt to manage the descent. The airplane subsequently descended and impacted the terrain while maintaining a nose-down attitude of approximately 30 degrees.

The investigation

Investigation into the mechanical failure focused on the condition of the flight controls following the accident. Examination revealed that the control stick had separated from its attachment point during the climb. No other mechanical anomalies were cited as contributing factors to the separation event.

Findings

The pilot provided a specific explanation for the mechanical failure during post-accident interviews. He stated that he had improperly installed the control stick during previous preventative maintenance procedures. This improper installation is identified as the primary reason the component failed under operational loads during flight.
