NTSB narrative
The pilot reported that he was landing the airplane in calm wind conditions. The airplane touched down midway down the runway at stall speed. Upon touchdown, the pilot retracted the flaps and applied brake pressure, including full aft elevator, in an attempt to bring the airplane to a stop. With the end of the runway approaching, the pilot applied left brake in an effort to turn the airplane to the left and the airplane nosed over off the end of the runway. The pilot stated that he checked the brakes prior to flight, but felt that they did not function normally during the landing. A witness reported that when the airplane was landing, it floated in ground effect until about 100 feet beyond midfield. The landing gear contacted the runway and the airplane continued to decelerate until disappearing over the end of the runway. According to a Federal Aviation Administration (FAA) inspector that responded to the accident, skid marks led from the runway to the location where the airplane came to rest. The FAA inspector examined the braking system following the accident and found no mechanical anomalies. At the time of this writing, the pilot had not submitted NTSB Form 6120.1, the Pilot/Operator Aircraft Accident/Incident Report.
Probable cause
The pilot's misjudged approach and failure to attain the proper touchdown point, which resulted in a runway overrun.

- 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. 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.
