What happened
The incident occurred while the pilot was conducting touch-and-go landings at a grass airstrip. During the approach phase, the airplane's engine suddenly lost power. According to the pilot's account, one cylinder began to lose power, which prevented the aircraft from maintaining altitude.
With insufficient thrust to continue the flight, the pilot initiated an emergency forced landing off the airport grounds. The aircraft descended into a wooded area and impacted trees, resulting in significant damage to the airframe.
The investigation
The investigation relied primarily on the pilot's narrative regarding the mechanical failure. No further physical examination of the engine components was detailed in the provided source text, but the pilot confirmed that a single cylinder was responsible for the loss of power.
