## NTSB investigations (10)

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 WPR27LA020](https://openairdocs.org/ntsb/WPR27LA020), Oct 17, 2026: Maule M-7-260 (N3217V), Sea Ranch, CA, investigation ongoing
- [NTSB ERA26LA184](https://openairdocs.org/ntsb/ERA26LA184), Apr 23, 2026: Maule M-7-260C (N41S), Tampa, FL, substantial damage. Probable cause: The pilot’s failure to maintain directional control of the airplane during the aborted landing, which resulted in a runway excursion, collision with a runway sign, and nose over.
