Overview
A pilot experienced a complete engine failure while returning to land. The pilot reported completing a before-landing check and rechecked the carburetor heat following the initial power loss. The sequence of events was described as typical of carburetor ice failures.
Sequence of Events
During the landing approach, the pilot encountered a loss of engine power. After completing the before-landing checklist, the pilot reengaged the carburetor heat control. Despite these actions, the engine failed completely. The pilot reported that the airplane had good ventilation with the windows closed, and cabin heat was used during the short flight.
Wreckage Examination
Examination of the wreckage did not reveal any mechanical malfunction that would have prevented normal engine operation. However, the inspection disclosed cracks in the muffler assembly. The presence of these cracks was noted, but they were not linked to the engine failure.
Additional Details
The pilot stated that cabin heat was used during the flight. The source does not specify the aircraft type, registration, date, operator, or location. No injuries or damage beyond the engine failure are reported. The investigation concluded that the engine failure was consistent with carburetor ice formation, given the absence of mechanical issues and the typical sequence of events.
