Investigator assessment
Analysis narrative
The pilot of the tailwheel bush airplane stated that he landed at a friend’s field (not an airstrip) and had never landed there before. The landing was uneventful, and the airplane touched down below 25 mph. After the airplane slowed further, the pilot attempted to taxi the airplane from the field to the driveway of the residence. The airplane subsequently traveled over soft ground and nosed over, coming to rest inverted. The pilot added that there were no preimpact mechanical malfunctions with the airplane. Examination of the airplane revealed substantial damage to the fuselage and vertical stabilizer.
