| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that he completed several takeoffs and landings and then made a scenic flight in the vicinity of the airport. As he was preparing to land, the pilot noticed a "considerable" loss of engine power, which he attributed to carburetor ice. As in the past, he applied carburetor heat, but the airplane would not climb and it was rapidly losing altitude. The pilot decided to land on the road next to the airport, but, with the loss of engine power, the airplane "dropped" over some trees and impacted a power pole. The airplane then spun around and collided with a pole barn. Ground slash marks and propeller blade leading edge damage indicated that the engine was still under partial power when the airplane hit the ground. The pilot did not note any preexisting mechanical anomalies that would have precluded normal operation. A Federal Aviation Administration carburetor icing probability chart indicated the probability of "serious icing at glide power." The pilot stated that he should have applied carburetor heat earlier in the approach.
Probable Cause: The pilot's delayed use of carburetor heat during the approach to landing, which resulted in the formation of carburetor ice, a partial loss of engine power, and the airplane's subsequent inability to sustain flight.
