NTSB narrative
The pilot circled the runway to determine the wind direction and examine the runway surface conditions. The runway surface consisted of deteriorated asphalt and gravel. The pilot reportedly touched down 1/3 the way down the runway and experienced a lack of braking effectiveness. He then pushed the brake pedal to the floor as he neared the end of the runway. The airplane exited the runway near the departure end, continued across the airport property, and impacted a small berm before coming to rest near a building.
The first identifiable marks on the runway were skid marks that began 2,600 ft down the 3,500 ft long runway and continued off the runway. Tire marks continued over the rough terrain, over the berm and through a barbed wire fence before where the airplane came to rest. It is likely that the airplane’s brakes were not effective due to the deteriorated asphalt and gravel on the runway surface. Also, it is likely that the pilot applied an abundance of pressure due to the lack of runway remaining, preventing the proper braking for the runway surface condition.
During the postaccident examination the right main landing gear brake line was separated near the caliper and line fitting. The line was examined and determined that the fracture surfaces were consistent with an overstress fracture. It likely that the line was damaged during the accident sequence. The pilot’s decision to land long on a gravel runway likely resulted in an inability to maintain control of the airplane during the landing roll.
Probable cause
The pilot’s failure to attain the proper touchdown point on a graveled surfaced runway with insufficient landing performance and subsequent loss of control during the landing roll.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, cause areas. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
