Probable cause
The pilot's continued flight into adverse weather (icing conditions), which resulted in a loss of engine power during a go-around. Factors contributing to the accident were icing conditions, and carburetor/induction icing.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The commercial certificated pilot was conducting a solo cross-country flight in a tailwheel-equipped airplane under Title 14, CFR Part 91, when the accident occurred. He reported that he received a special VFR clearance at the departure airport, and as soon as he cleared class E airspace, the airplane started to accumulate rime ice on the wings' leading edges and windshield. He reported that three-quarters of the way to his destination the windshield was suddenly covered with rime ice, and that his destination was the closest airport. At the destination airport, he said the visibility was one-half to one mile in fog and freezing drizzle. On short final he reported that visibility was deteriorating, and he elected to go-around. He said the throttle did not respond, the engine lost power, and the airplane descended into trees. The pilot attributed the engine losing power to a combination of carburetor and induction icing. The pilot reported that there were no known mechanical problems with the airplane prior to the accident. He said during the accident the airplane received damage to the right wing and lift-strut, right aileron, and right elevator. Due to the remote location, the airplane was not examined by the National Transportation Safety Board.

He said the throttle did not respond, the engine quit, and the airplane descended into trees. The pilot attributed the engine quitting to a combination of carburetor and induction icing.
