Accident Overview
A private pilot, who had accumulated 315 total flight hours with 53 hours in the accident airplane, experienced a loss of propeller and throttle control while descending at the conclusion of a local flight. Recognizing that he could not reach the intended airfield, the pilot elected to land in a plowed field.
Landing Attempt
During the approach, the pilot slowed the airplane and lowered the flaps to 40 degrees. The airspeed decreased to approximately 55 knots, at which point the stall warning horn sounded. The airplane subsequently impacted the ground, bounced forward, and the nose landing gear assembly collapsed. The aircraft came to rest in an inverted position.
Environmental Conditions
According to a carburetor icing probability chart, carburetor icing was possible at glide and cruise power settings given the ambient temperature of 70 degrees Fahrenheit and a dew point of 37 degrees Fahrenheit. The pilot reported that he did not use carburetor heat during the descent.
Pilot Background
The pilot was a private pilot with 315 hours of flight experience, of which 53 hours were in the accident airplane.
