NTSB Factual Report

The pilot stated that he and his co-pilot arrived over their destination airport, Denton, Montana, and circled to check the grass strip for obstructions and general field conditions. Satisfied with the appearance of the runway they decided to land. Towards the end of the landing rollout he felt that the tires were sinking and dragging excessively. Fearing getting stuck he elected to abort the landing and continue with a takeoff. After liftoff, the airplane failed to clear a barbed wire fence at the end of the runway and the nose landing gear tire snagged the fence and the airplane nosed over on its back. The pilot stated that the airplane and engine had no mechanical failures or malfunctions during the flight.

NTSB Probable Cause

The pilot's decision to abort the landing with insufficient runway available to gurantee obstruction clearance.
