## 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 FTW99LA077](https://openairdocs.org/ntsb/FTW99LA077), Feb 1, 1999: Bell 206L-3 (N6603X), West Delta 105b, substantial damage. Probable cause: The pilot's failure to maintain clearance with the oil platform's windsock on final approach to landing.

## FAA accident and incident reports (2)
