Incident Overview
An aircraft experienced a loss of engine power during descent and subsequently crashed into trees. The pilot reported that the weather conditions were visual meteorological conditions (VMC) and that no flight plan had been filed for the flight.
Pilot Statement
According to the pilot, the descent was being conducted with reduced power. When he activated the carburetor heat, the engine began to miss. In response, he turned the carburetor heat off. At that point, the aircraft's altitude was low. The pilot then turned the aircraft and performed an uphill landing.
Investigation Findings
Post-accident examination of the powerplant revealed a single discrepancy: debris was found inside the carburetor. This debris had plugged the internal passages, which created conditions mimicking carburetor ice. No other issues were identified with the engine or related systems.
Outcome
The aircraft came to rest in trees following the forced landing. The specific type of aircraft, registration markings, number of occupants, and extent of injuries or damage were not disclosed in the investigation source.
