## Narrative

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

(-23)ENROUTE FROM MDW TO MHT THE FLIGHT EXPERIENCED A LOSS OF CABIN PRESSURE AT FLIGHT LEVEL 370, DURING THE DESCEND TO 10,000 FEET THE CABIN PRESSURE WAS REPORTED TO REACH 24,000 FEET. THE OXYGEN MASKS DEPLOYED, HOWEVER THERE WERE SIX PSU LOCATIONS THAT FAILED TO ACTIVATE THE OXYGEN GENERATORS AND START THE FLOW OF OXYGEN.  THE INITIAL CAUSE OF THE LOSS OF PRESSURIZATION WAS A FAILURE TO THE CABIN OUTFLOW VALVE CONNECTOR.  THE CONNECTOR WAS REPLACED AND CORRECTED THE MALFUNCTION OF THE PRESSURIZATION SYSTEM.  THE CAUSE OF THE OXYGEN GENERATOR ACTIVATION FAILURE IS STILL UNDER INVESTIGATION BY THE SWA, CMU, SWA, FAA, AEG, AND BOEING.

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.
