Primary finding
Probable cause
The pilot’s selection of an unsuitable landing site, which resulted in the main landing gear wheels breaking through the snow and the airplane nosing over.
Investigator assessment
Analysis narrative
The pilot reported that, to avoid excessive wear on the airplane’s Bushwheels, he decided to not land on the paved runway and instead he landed on the snow-covered gravel runway. During landing, the airplane decelerated rapidly as the main wheels touched down into the snow. The airplane subsequently nosed over sustaining substantial damage to the right-wing lift struts and rudder. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
