NTSB Narrative Summary Released at Completion of Accident

A certificated flight instructor (CFI) was providing flight instruction to a student pilot during civil twilight. The CFI reported that while on approach to an unlighted, snow-covered gravel runway, he instructed the student pilot to go-around when he realized that the airplane was not lined up with the runway. He said that his verbal command to immediately applying full engine power and initiate a go-around was followed, but the engine did not respond. The CFI took control of the airplane, confirmed that the throttle was at maximum, and then he landed the airplane in the deep snow. As the main and nose wheels touched down in the deep snow, the airplane decelerated rapidly, and the nose landing gear collapsed. The airplane sustained substantial damage to the fuselage and wings. An FAA airworthiness inspector reported that his postaccident inspection of the airplane disclosed a number of maintenance deficiencies, but found none that would have accounted for the loss of engine power.

NTSB Probable Cause Narrative

A loss of engine power for an undetermined reason during an attempted go-around, resulting in a forced landing and a collision with snow-covered terrain. A factor associated with the accident was the lack of suitable terrain for a forced landing.
