### Matched by engine (NONE)

None in force.

## Information bulletins (advisory)

None matched.

## 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 ERA23LA207](https://openairdocs.org/ntsb/ERA23LA207), Apr 15, 2023: Schweizer SGS 1-26E (N33873), Wake Forest, NC, substantial damage. Probable cause: The student pilot’s failure to maintain airspeed during the landing approach, which resulted in an exceedance of the glider’s critical angle of attack, an aerodynamic stall, and a loss of control.

## 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.
