## 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 ANC14CA087](https://openairdocs.org/ntsb/ANC14CA087), Sep 19, 2014: Helio H 250 (N333TB), Arctic Village, AK, substantial damage. Probable cause: The pilot's selection of an unsuitable landing/takeoff area, resulting in an inflight collision with terrain during takeoff.
- [NTSB ANC05LA097](https://openairdocs.org/ntsb/ANC05LA097), Jul 7, 2005: Helio H-250 (N333TB), Anchorage, AK, substantial damage. Probable cause: A fracture failure of the main landing gear leg during the landing roll, which resulted in the collapse of the main landing gear.
