## 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 WPR22LA084](https://openairdocs.org/ntsb/WPR22LA084), Jan 23, 2022: Bell UH-1E (N333XL), Gustine, CA, substantial damage. Probable cause: Failure of the 90° gearbox due to the lack of lubricating oil, which resulted in a loss of rotational drive to the tail rotor and a subsequent loss of control of the helicopter.

## 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.

- [Accident 20220123001259A](https://openairdocs.org/incident/20220123001259A), Jan 23, 2022: Bell UH-1E (N333XL), Gustine, CA, Destroyed. Pilot was performing aerial application, while performing turning maneuver loss control resulting in crash. No injuries, damage to crop field, and aircraft…
