The pilot had recently purchased an airplane and was ferrying it to his home airport. During the first leg of the trip, he reported that the engine’s rpm decreased two or three times from 3,200 to 2,800 rpm. The engine regained power shortly after the pilot applied carburetor heat. Shortly after departure on the second leg of the trip, the pilot felt a vibration in the engine, so he applied carburetor heat; however, the engine lost power and the airplane collided with trees in a wooded area. An examination of the engine did not reveal a reason for the power loss. A review of the carburetor icing probability chart indicated that the airplane was operating in an area that was associated with a risk of carburetor icing at glide power settings and light carburetor icing at cruise power. Because the airplane was being operated in an area of potential carburetor icing, and no anomalies could be found during postaccident testing, the engine likely lost power due to carburetor icing. However, the investigation was not able to determine that earlier application of carburetor heat would have prevented the loss of power.
Probable Cause: The loss of engine power as a result of carburetor icing.
