What happened
While cruising at approximately 1,000 feet above ground level, a Piper PA-22-20 experienced a reported partial loss of engine power. In response to the power loss, the pilot identified a long, flat field to serve as an emergency landing site.
The pilot performed the landing but noted that the aircraft touched down beyond the intended touchdown point. In an attempt to recover, the pilot elected to perform a go-around. During this maneuver, the aircraft lifted off from the field but failed to gain enough altitude to clear obstacles at the edge of the area, resulting in a collision with trees.
The investigation
An airframe and powerplant mechanic (A&P) performed an examination of the aircraft's engine. The inspection revealed no evidence of mechanical failure or malfunction that would account for the loss of power reported by the pilot.
