## NTSB investigations (2)

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 ANC23LA038](https://openairdocs.org/ntsb/ANC23LA038), May 22, 2023: Aerospatiale AS350B2 (N745RH), Honolulu, HI, substantial damage. Probable cause: The instructor pilot’s inadequate supervision of the pilot receiving instruction, which resulted in a hard landing, and substantial damage to the tail boom.
- [NTSB WPR14LA272](https://openairdocs.org/ntsb/WPR14LA272), Jun 29, 2014: Aerospatiale AS350B2 (N350CR), Dietrich, ID, substantial damage. Probable cause: The pilot’s sudden incapacitation from a previously undiagnosed medical condition while in cruise flight, which resulted in his inability to maintain helicopter control.

## FAA accident and incident reports (4)
