## Other investigations on N2581M (2)

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 ANC10CA042](https://openairdocs.org/ntsb/ANC10CA042), May 22, 2010: Piper PA-12 (N2581M), Chugiak, AK, substantial damage. Probable cause: The pilot's failure to maintain a proper glide path while landing, which resulted in an in-flight collision with a tree, and the collapse of the main landing gear during touchdown.
