What happened
During the landing phase, the pilot of the aircraft landed approximately one-quarter of the way down the 3,550-foot runway. The pilot reported that heavy braking was not applied until the aircraft had passed the midfield point of the runway. Consequently, the deceleration was insufficient to prevent the aircraft from overrunning the departure end of the runway. After exiting the runway, the aircraft veered down an embankment.
The airport is situated at an elevation of 5,743 feet mean sea level. While a bystander reported experiencing a strong northerly wind during the pilot's approach to runway 01, the pilot noted that both windsocks indicated calm conditions upon arrival at the airport.
The investigation
Investigators identified approximately 1,100 feet of heavy braking evidence on the surface of the turf runway. The pilot reported that no mechanical malfunctions had occurred with the aircraft during the flight.
