## Other investigations on N4839P (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 DEN08LA069](https://openairdocs.org/ntsb/DEN08LA069), Mar 29, 2008: Cessna P210N (N4839P), Elizabeth, CO, substantial damage. Probable cause: the loss of engine power due to the fatigue failure of the camshaft gear. Contributing to the accident was the lack of suitable terrain for the forced landing.
