## Other investigations on N1613M (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 ANC03LA031](https://openairdocs.org/ntsb/ANC03LA031), Mar 9, 2003: Cessna 185 (N1613M), Galena, AK, substantial damage. Probable cause: The failure of the airplane to climb after takeoff which resulted in an in-flight collision with terrain during an aborted landing attempt.
- [NTSB LAX98LA299](https://openairdocs.org/ntsb/LAX98LA299), Sep 20, 1998: Cessna 185E (N1613M), Mesa, AZ, substantial damage. Probable cause: The failure of the wheel assembly retention nuts and subsequent wheel separation.
