## Other investigations on N4145Y (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 LAX02LA258](https://openairdocs.org/ntsb/LAX02LA258), Aug 16, 2002: Cessna 185A (N4145Y), Fillmore, CA, substantial damage. Probable cause: the pilot's continued visual flight rules flight into instrument meteorological conditions, which resulted in the in-flight collision with terrain during a climb.
- [NTSB ANC95LA140](https://openairdocs.org/ntsb/ANC95LA140), Aug 15, 1995: Cessna 185A (N4145Y), Teller, AK, substantial damage. Probable cause: DEFLATION OF THE LEFT MAIN TUNDRA TIRE DUE TO VALVE STEM DAMAGE (FAILURE) WHEN THE TIRE ROTATED INDEPENDENTLY OF THE WHEEL RIM, RESULTING IN LOSS OF DIRECTIONAL CONTROL AND A GROUND SWERVE.
- [NTSB ANC90LA092](https://openairdocs.org/ntsb/ANC90LA092), Jun 22, 1990: Cessna 185-A (N4145Y), Anchorage, AK, substantial damage. Probable cause: FAILURE OF THE RIGHT MAIN GEAR TORQUE PLATE CAUSING AN UNCONTROLLABLE LANDING ROLL OUT.
