What happened
The pilot of a Pitts Special PA-22 was conducting flight operations from a private strip, specifically practicing departures from a confined field. According to the pilot, the aircraft had been operating normally for approximately thirty minutes prior to the incident. During the climbout phase from the private runway, the engine ceased operation unexpectedly. The pilot initiated a forced landing procedure, targeting an open field located just beyond a row of tall trees. Although the pilot identified a generous area suitable for landing, the aircraft struck the ground with significant force approximately 100 feet beyond the tree line. This impact resulted in the collapse of the landing gear and damage to the left wing. The aircraft came to rest in a flat pitch attitude.
The investigation
A post-accident inspection of the Pitts Special PA-22 was conducted to determine the cause of the engine failure. Examination of the airframe revealed no mechanical discrepancies or failures affecting any flight control systems or engine components. Investigators confirmed that the aircraft was STC'd for use of automotive fuel and that sufficient, uncontaminated fuel was on board at the time of the accident. The inspection ruled out mechanical failure as the primary cause of the power loss.
Findings
The investigation determined that the engine quit during climbout despite normal prior operation and adequate fuel supply. The pilot's decision to land in a field beyond the tree line, while having ample space available, resulted in a high-energy impact. The collision with the ground caused substantial structural damage to the airframe, specifically affecting the landing gear assembly and the left wing structure.
