Flight Sequence
The pilot initiated a descent from 5,000 feet with reduced engine power but did not apply carburetor heat. While passing through 3,500 feet, the pilot advanced the throttle, but the engine did not accelerate and subsequently ceased producing power entirely. Despite the pilot's corrective actions, the engine could not be restarted.
Forced Landing
With the engine inoperative, the pilot conducted a forced landing. During the landing attempt, the left wing struck a tree.
Post-Impact Inspection
Examination of the aircraft after the accident revealed no fuel present in the fuel system. The carburetor had been broken open by the ground impact. The pilot reported that both the fuel quantity gauge and fuel pressure gauge were indicating properly prior to the tree impact.
Icing Conditions
An icing probability chart indicated that the ambient temperature and dew point at the time were within the range conducive to serious carburetor icing at glide power settings.
