The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19790824029079A](https://openairdocs.org/incident/19790824029079A), Aug 24, 1979: Hiller UH12E, Somerton, AZ, Destroyed. Bolt that secures the fore and aft cyclic control backed out.
