## 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 19800320045509I](https://openairdocs.org/incident/19800320045509I), Mar 20, 1980: Doug DC931, Philadelphia, PA. Rapid rise in cabin altitude, unable to control. Pilot descended. All oxygen masks did not deploy.

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.
