## Information bulletins (advisory)

None matched.

## 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 CEN22LA147](https://openairdocs.org/ntsb/CEN22LA147), Mar 13, 2022: Sikorsky S-76D (N761AF), Texarkana, AR, substantial damage. Probable cause: The pilot’s failure to maintain adequate clearance during landing on a rooftop helipad.
- [NTSB CEN19LA146](https://openairdocs.org/ntsb/CEN19LA146), May 15, 2019: Sikorsky S76 (N761AF), Morrilton, AR, substantial damage. Probable cause: The improper securing of the exhaust duct bolts, which resulted in the duct becoming unseated and substantial heat damage to the tail rotor drive shaft.

## FAA accident and incident reports (2)

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.
