## NTSB investigations (5)

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 ERA24LA387](https://openairdocs.org/ntsb/ERA24LA387), Sep 20, 2024: Agustawestland Philadelphia AW119MKII (N281MC), Canandaigua, NY, substantial damage.
