## 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 FTW91LA098](https://openairdocs.org/ntsb/FTW91LA098), Jun 17, 1991: Sikorsky S76A (N5418N), Ship Shoal 290k, destroyed. Probable cause: THE COPILOT'S REDUCTION OF POWER TO GROUND IDLE ON BOTH ENGINES. FACTORS WERE THE PILOT'S POOR LANDING TECHNIQUE AND HIS FAILURE TO ESTABLISH ADEQUATE CREW COORDINATION.

## 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.
