Accident Overview
A pilot conducting a low-level flight while chasing coyotes over open, snow-covered terrain reported that the airplane's engine began to lose power and run roughly, accompanied by a loss of altitude. The pilot responded by applying carburetor heat and advancing the throttle to full power. As the engine started to regain power, the airplane's main wheels broke through the crusty top layer of the snow.
Sequence of Events
The airplane then began to slow down. When the propeller contacted the snow, the pilot reduced power and attempted to transition to a landing. Despite holding the control stick fully aft, the airplane nosed over onto its back. The accident resulted in damage to the vertical stabilizer and bending of both left wing lift struts.
Pilot Statement
According to the pilot, there were no problems with the engine aside from an accumulation of carburetor ice.
