## Other investigations on N7471J (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

- [NTSB FTW96LA025](https://openairdocs.org/ntsb/FTW96LA025), Oct 24, 1995: Piper PA-28R-180 (N7471J), Dibble, OK, substantial damage. Probable cause: an overload failure of the #1 connecting rod bolt and resulting connecting rod fatigue failure. A factor was the lack of suitable terrain for the forced landing.
