## Narrative

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

(-23) MES FLIGHT 3690 DEPARTED MSP ON 10/24/2004 AT 0800. THE PILOT NOT FLYING (CAPTAIN) FAILED TO SET THE PRESSURIZATION SYSTEM FOR TAKEOFF, CLIMB, AND CRUISE. THE AIRCRAFT DID NOT PRESSURIZE CAUSING THE OXYGEN MASKS TO AUTOMATICALLY DEPLOY AT 13,500 FEET MSL. THE AIRCRAFT RETURNED TO MSP AND LANDED WITHOUT FURTHER INCIDENT. CAPTAIN AND FIRST OFFICER WERE REMOVED FROM LINE FLYING. A CHECK WAS GIVEN BY A MESABA AIRLINES, INC. CHECK PILOT ON OCTOBER 31, 2004. BOTH PILOTS FAILED THE CHECK, WERE PUT INTO A TRAINING PROGRAM OF ADDITIONAL GROUND SCHOOL, AND SIMULATOR TRAINING. A PROFICIENCY CHECK WAS GIVEN TO BOTH PILOTS, WHICH WERE PASSED AND THE PILOTS RETURNED TO LINE FLYING. ALL CHECKS WERE OBSERVED BY FAA INSPECTORS.

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.
