## 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 SEA90LA137](https://openairdocs.org/ntsb/SEA90LA137), Jul 16, 1990: Sikorsky S-58BT (N439DS), Ovando, MT, substantial damage. Probable cause: THE PILOT DID NOT MAINTAIN ROTOR RPM AFTER A COMPRESSOR ASSEMBLY BLADE FAILURE. A RELATED FACTOR WAS AN INADEQUATE AUTOROTATION RESULTING IN A HARD LANDING.

## 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 19900716026329A](https://openairdocs.org/incident/19900716026329A), Jul 16, 1990: Skrsky S58BT (N439DS), Ovando, MT, Substantial damage. NR1 engine failed at hover and fire from tailpipe. Delayed autorotation. Hard landing. Engine overheated in hover.
