## NTSB investigations (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 WPR26LA368](https://openairdocs.org/ntsb/WPR26LA368), Sep 30, 2026: Gronberger Sergio A Sportsman GS-2 (N360ET), Lake Goodwin, WA, substantial damage, investigation ongoing
