## Other investigations on N731SV (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 CHI05CA201](https://openairdocs.org/ntsb/CHI05CA201), Jul 26, 2005: Cessna 188 (N731SV), Mexico, MO, substantial damage. Probable cause: The pilot's failure to maintain directional control. Factors were the grass terrain adjacent to the runway and the collapse of the main landing gear.
