## Other investigations on N657Y (3)

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 SEA04LA093](https://openairdocs.org/ntsb/SEA04LA093), Jun 1, 2004: Grumman G-164 (N657Y), Rexburg, ID, substantial damage. Probable cause: The pilot's failure to maintain clearance from an object while maneuvering during an aerial application flight. Contributing factors were the pilot's diverted attention and the irrigation pivot.
