## Other investigations on N3613M (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 ANC11CA025](https://openairdocs.org/ntsb/ANC11CA025), Apr 10, 2011: Piper PA-12 (N3613M), Delta Junction, AK, substantial damage. Probable cause: The pilot's misjudged altitude while landing in bright sunlight on an airstrip surrounded by snow, resulting in an undershoot and a nose over.
- [NTSB ANC07CA034](https://openairdocs.org/ntsb/ANC07CA034), Apr 29, 2007: Piper PA-12 (N3613M), Delta Junction, AK, substantial damage. Probable cause: The damaged and deflated over-sized tire on the main landing gear, which precipitated a loss of directional control during landing.
