Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

The pilot's failure to apply carburetor heat during the before takeoff check as part of the ground check. A factor was weather conditions favorable for the formation of carburetor ice.

Analysis

During climbout the pilot experienced a partial loss of engine power and attempted a forced landing in a wooded area. A witness reported that the engine cut out as the airplane flew over his location. Seconds later the airplane crashed in the adjacent woods and burned. Examination of the accident site disclosed propeller slash marks on freshly cut trees along the wreckage path. The wreckage examination failed to reveal a mechanical component failure or a system malfunction with the powerplant or airframe. However, the local weather report indicated conditions favorable for the formulation of carburetor ice. According to the owner's handbook, the pilot should check the carburetor heat during the ground check to eliminate the formation of carburetor ice during taxi.
