## NTSB investigations (1)

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 ANC12CA047](https://openairdocs.org/ntsb/ANC12CA047), May 13, 2012: Maule M-4-220C (N615SD), Sterling, AK, substantial damage.
