## NTSB investigations on N4H (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 UNK64X2607](https://openairdocs.org/ntsb/UNK64X2607), Jul 2, 1964: Cessna 170 (N4H), Ft Smith, AR, substantial damage
