Aircraft involved

N9639D Piper PA-22-150 Minor

Probable cause & findings

The pilot’s failure to attain the proper touchdown point which resulted in a runway overrun, collision with an airport boundary fence, and a nose over event.

Factual narrative

The pilot reported that after touch down, the airplane overran the runway, passed thru the airport boundary fence, nosed over, and came to rest inverted, which resulted in substantial damage to the left wing lift strut. A post-accident examination revealed no mechanical malfunctions or anomalies that would have precluded normal operation. Source: NTSB Aviation Accident Database Retrieved: 2026-02-12
