## 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 MIA95LA225](https://openairdocs.org/ntsb/MIA95LA225), Sep 17, 1995: Schweizer SGU-2-22K (N2717Z), Picayune, MS, destroyed. Probable cause: The pilot-in-command's disregard of a weather forecast and flight into known adverse weather condition (thunderstorm). The thunderstorm, and associated wind gusts, were factors.
- [NTSB MKC77FER34](https://openairdocs.org/ntsb/MKC77FER34), Apr 17, 1977: Schweizer SGU2 (N2717Z), Cloquet, MN, substantial damage

## 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.
