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) N541CV, a Cessna 500-560, was enroute from madison, WI, to scottsdale, AZ. At flight level 430 the cabin door started to make a noise. The aircraft still was pressurized. The pilot stated that the noise went away between FL200 and FL180. The aircraft diverted to Grand Island, NE, and landed without incident. The crew contacted their company maintenance department who contacted Cessna aircraft. The technical people theorized that moisture had entered the system, froze at altitude, blocking the hole that allows air to enter the seal, and then thawed during the descent. No problem with the door seal was found.
