## Other investigations on N6417V (3)

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 FTW94LA147](https://openairdocs.org/ntsb/FTW94LA147), May 8, 1994: Hiller UH-12B (N6417V), Crystal Beach, TX, substantial damage. Probable cause: THE PILOT'S IMPROPER AUTOROTATION TOUCHDOWN, WHICH RSULTED IN THE HARD LANDING. A FACTOR WAS THE POWER LOSS DUE TO WATER CONTAMINATED FUEL.
