Accident Description
The airplane was descending toward the airport when the engine lost power. The pilot applied carburetor heat, which restored power until the next descent. During the second descent, the pilot initiated with full carburetor heat applied, but power was lost again and could not be restored. The pilot subsequently made an off-airport forced landing at night, during which the airplane struck trees and then the ground.
Investigation Findings
No mechanical problems were found during the post-accident examination. Fuel was present in the tanks at the time of the power loss. Weather conditions were conducive to severe carburetor icing.
Conclusion
The engine power loss occurred under weather conditions favorable for carburetor icing, and no mechanical deficiencies were identified.
