## Other investigations on N3471Z (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 CEN13CA108](https://openairdocs.org/ntsb/CEN13CA108), Dec 11, 2012: Piper PA-18-150 (N3471Z), Okaton, SD, substantial damage. Probable cause: The pilot's failure to perform an adequate preflight inspection of the airplane and obstruction of the aileron control system by snow and ice, which led to a loss of control during flight.
