## Other investigations on N7646 (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 CHI00LA033](https://openairdocs.org/ntsb/CHI00LA033), Nov 13, 1999: Schweizer SGS-1-34 (N7646), East Lynne, MO, substantial damage. Probable cause: inadequate airspeed and a subsequent stall. Factors associated with the accident were the tailwind, the pilot's misjudgment of the wind condition, and poor inflight planning.
