From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) Nwa flight 545 was cleared to FL280 and leveled off at that altitude. The cabin pressue continued to increase with the outflow valve fully closed and the captian requested a descent to FL180. He was cleared to FL270, but the cabin pressure continued to increase. The captain declared an emergency due to the pressurization problem. ATC cleared him to FL240 where the cabin pressure slowly returned to normal.
