## NTSB investigations (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 ANC95FA104](https://openairdocs.org/ntsb/ANC95FA104), Jul 15, 1995: Piper PA-18 (N7531K), Naknek, AK, destroyed, 2 fatal. Probable cause: INADEQUATE VISUAL LOOKOUT BY THE PILOT OF THE PIPER PA-18. THE PA-18 PILOT'S DIVERTED ATTENTION WAS A RELATED FACTOR.
