Accident Overview
The pilot was cruising at 7,500 feet while en route and had been in a gradual descent for about 10 minutes toward the intended landing point. During the descent, the engine lost power. The pilot switched fuel tanks, applied carburetor heat for approximately 20 seconds, and moved the throttle in and out. These actions did not restore engine power.
Forced Landing
Unable to restore power, the pilot began searching for a suitable location for a power-off forced landing. No smooth terrain was available in the area. The pilot slowed the aircraft and flew it onto forested terrain in a landing attitude. During the landing sequence, the aircraft collided with several trees.
Post-Accident Inspection
A post-accident examination of the aircraft revealed that the wire from the carburetor heat control was no longer attached to the bolt in the fitting on the carburetor heat box actuation lever. The wire had come out of the hole in the bolt, but the crush washer, castle nut, and cotter pin remained attached to the bolt. Additionally, the carburetor heat control wire housing was found disconnected from its mounting point.
Pilot Statement
According to the pilot, the carburetor heat was tested as part of the pre-takeoff check. At that time, there was a significant drop in RPM when the carburetor heat was actuated.
