## FAA reports on this event (1)

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

- [Incident 19791112053689I](https://openairdocs.org/incident/19791112053689I), Nov 12, 1979: Cessna 500CESSNA, Dallas, TX. Pilot detected split flap condition during training flight. Due to lack of lubrication, flap system elements failed.

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.
