## 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 CEN22LA118](https://openairdocs.org/ntsb/CEN22LA118), Feb 12, 2022: Mooney M20J (N201VZ), Katy, TX, substantial damage. Probable cause: The pilot’s failure to maintain a proper glidepath while on the final approach segment of the traffic pattern in dark night conditions.

## FAA accident and incident reports (4)
