## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) ON CLIMB OUT FROM PHOENIX SKY HARBOR INTERNATIONAL AIRPORT TO MINNEAPOLIS, MINNESOTA AT FLIGHT LEVEL 190 THERE WAS A LOUD BANG AND AN AIRFRAME SHUDDER. THE PRESSURIZATION WAS CHECKED AND THE OUTFLOW VALVE WAS FOUND TO BE FULL CLOSED WHILE THE CABIN ALTITUDE WAS CLIMBING. THE CREW INITIATED AN EMERGENCY DESCENT, DECLARED AN EMERGENCY AND RETURNED TO PHOENIX, WITHOUT FURTHER INCIDENT. MAINTENANCE PERSONNEL FOUND A BLOWN OUT DUCT IN THE RIGHT AIR CONDITIONING BAY. THE CHECK VALVE THAT PREVENTS REVERSE AIRFLOW FROM THE MIX MANIFOLD ALSO FAILED. THE FLAPPER DISK WAS TORN OFF AND FOUND IN THE DUCTING. THAT IS WHY THE AIRPLANE PRESSURIZATION COULD NOT BE MAINTAINED. MAINTENANCE PERSONNEL REMOVED AND REPLACED THE DUCT ASSEMBLY, PART #213N403 AND THE CHECK VALVE, GARRETT PART #3202142-1.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft 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. For accidents, the NTSB's own investigation is the fuller record.
