## NTSB investigations (4)

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 GAA26WA227](https://openairdocs.org/ntsb/GAA26WA227), Jun 24, 2026: Lake LA4 (N9777), Egelsbach, Germany, substantial damage
