## 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 WPR26FA301](https://openairdocs.org/ntsb/WPR26FA301), Aug 11, 2026: New Glasair Sportsman 2 Plus 2 (N202AZ), Pine, AZ, destroyed, 2 fatal, investigation ongoing
