## 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 LAX99LA300](https://openairdocs.org/ntsb/LAX99LA300), Sep 9, 1999: Robinson R-22-BETA (N4076Z), Piute, NV, substantial damage. Probable cause: the failure of the pilot to maintain rotor rpm while practicing autorotations, resulting in a hard landing and roll over.

## FAA accident and incident reports (1)

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
