Accident Overview
A pilot experienced a loss of engine power shortly after takeoff, resulting in a forced landing that brought the aircraft into contact with trees. The pilot reported that the engine lost RPM, sputtered, and stopped approximately 10 to 12 seconds after departure.
Pilot Report
According to the pilot, the engine progressively lost revolutions per minute, began sputtering, and ultimately ceased operation. The pilot executed a forced landing, but the airplane struck trees during the descent. The pilot also stated that a carburetor heat check had been performed during the pre-takeoff run-up.
Investigation
FAA inspectors examined the airplane following the incident and were unable to identify any mechanical anomaly within the engine that would account for the power loss. During the wreckage examination, an inspector noted that the carburetor heat control was in the 'off' position.
Weather Conditions
At the time of the incident, the ambient temperature was 51 degrees Fahrenheit, and the dew point was 43 degrees Fahrenheit. These temperature and dew point values are conducive to the formation of serious carburetor icing.
