## 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 19790206002429A](https://openairdocs.org/incident/19790206002429A), Feb 6, 1979: Univar F1, Mason, MI, Substantial damage. Brake failure on landing. O rings on both wheel brake pistons had failed due to age deterioration and wear.

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.
