## Other investigations on N12MM (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 GAA15CA175](https://openairdocs.org/ntsb/GAA15CA175), Jul 9, 2015: Cessna 150J (N12MM), Renton, WA, substantial damage. Probable cause: The pilot's failure to maintain adequate airspeed, which resulted in the airplane exceeding its critical angle of attack and a subsequent aerodynamic stall/spin.
