## FAA reports on this event (1)

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

- [Accident 19840518052139A](https://openairdocs.org/incident/19840518052139A), May 18, 1984: Eirvon PIK20E, Thomasville, NC, Substantial damage. Crash occurred during emergency landing. Engine failed shortly after self launching and climbing to about 150 feet.

## Other investigations on N35LP (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 DEN00LA096](https://openairdocs.org/ntsb/DEN00LA096), May 27, 2000: Eiriavion PIK 20E (N35LP), Hurricane, UT, substantial damage. Probable cause: The complete loss of power due to the separation of the magneto ground lead and the rough and unsuitable terrain during the forced landing.
