## NTSB investigations (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 ANC13FA004](https://openairdocs.org/ntsb/ANC13FA004), Oct 15, 2012: Grumman Aircraft ENG C-1A (N27PH), Willow, AK, destroyed, 1 fatal. Probable cause: The pilot’s loss of control of the airplane for reasons that could not be determined because the wreckage was not recovered from the accident site.
- [NTSB CHI02LA254](https://openairdocs.org/ntsb/CHI02LA254), Aug 18, 2002: Grumman C-1A (N189G), Roseville, IL, substantial damage.
