## Other investigations on N40289 (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 DEN08LA071](https://openairdocs.org/ntsb/DEN08LA071), Apr 4, 2008: Hiller UH-12E (N40289), La Porte, TX, substantial damage. Probable cause: The loss of tail rotor effectiveness. Contributing factors were the sudden windshift to a tailwind, and the pilot initiating a hovering turn in ground effect.
