Narrative:

On takeoff out of mobile, al, bound for cvg, the aircraft would not pressurize. We had only flight, and cabin crew, on board, the flight diverted to atl with no further problems. It was later determined that the east&east compartment door had not been closed correctly. This was after landing atl. Also, the east&east door warning system in the cockpit, was found to be inoperative. We had no abnormal indications, in the cockpit, other than a lack of pressurization. I completed a walk- a-round inspection prior to pushback, but obviously did not catch the door. In the area of contributing factors: extensive maintenance had been performed on the aircraft for several hours, plus 2 separate engine runups performed by flight crew. Numerous bays and panels were opened and removed by maintenance personnel. On the exterior inspection I found nicks in fan blades from the last engine runup. I did a complete inspection but concentrated on all the panels and bays that had been opened. Also we were under time pressure to get the aircraft to cvg. Maintenance blended the nicks on the blades, and we were dispatched. All these distrs plus the warning system being inoperative (unknown to the crew) caused the problem. Supplemental information from acn 296861: the captain did the last walk around and all appeared to be ok. However we were both in the cockpit reaccomplishing a complete preflight (interior inspection). While the maintenance man finished up his work outside and completed the logbook.

Original NASA ASRS Text

Title: AFTER EXTENSIVE DELAY (MECHANICAL PROBS), AN ACR FLC DEPARTED WITHOUT PERFORMING POST-MAINT WALK-AROUND. ACFT FAILED TO PRESSURIZE, DUE TO AN OPEN EQUIP BAY DOOR.

Narrative: ON TKOF OUT OF MOBILE, AL, BOUND FOR CVG, THE ACFT WOULD NOT PRESSURIZE. WE HAD ONLY FLT, AND CABIN CREW, ON BOARD, THE FLT DIVERTED TO ATL WITH NO FURTHER PROBS. IT WAS LATER DETERMINED THAT THE E&E COMPARTMENT DOOR HAD NOT BEEN CLOSED CORRECTLY. THIS WAS AFTER LNDG ATL. ALSO, THE E&E DOOR WARNING SYS IN THE COCKPIT, WAS FOUND TO BE INOP. WE HAD NO ABNORMAL INDICATIONS, IN THE COCKPIT, OTHER THAN A LACK OF PRESSURIZATION. I COMPLETED A WALK- A-ROUND INSPECTION PRIOR TO PUSHBACK, BUT OBVIOUSLY DID NOT CATCH THE DOOR. IN THE AREA OF CONTRIBUTING FACTORS: EXTENSIVE MAINT HAD BEEN PERFORMED ON THE ACFT FOR SEVERAL HRS, PLUS 2 SEPARATE ENG RUNUPS PERFORMED BY FLC. NUMEROUS BAYS AND PANELS WERE OPENED AND REMOVED BY MAINT PERSONNEL. ON THE EXTERIOR INSPECTION I FOUND NICKS IN FAN BLADES FROM THE LAST ENG RUNUP. I DID A COMPLETE INSPECTION BUT CONCENTRATED ON ALL THE PANELS AND BAYS THAT HAD BEEN OPENED. ALSO WE WERE UNDER TIME PRESSURE TO GET THE ACFT TO CVG. MAINT BLENDED THE NICKS ON THE BLADES, AND WE WERE DISPATCHED. ALL THESE DISTRS PLUS THE WARNING SYS BEING INOP (UNKNOWN TO THE CREW) CAUSED THE PROB. SUPPLEMENTAL INFO FROM ACN 296861: THE CAPT DID THE LAST WALK AROUND AND ALL APPEARED TO BE OK. HOWEVER WE WERE BOTH IN THE COCKPIT REACCOMPLISHING A COMPLETE PREFLT (INTERIOR INSPECTION). WHILE THE MAINT MAN FINISHED UP HIS WORK OUTSIDE AND COMPLETED THE LOGBOOK.

After extensive delay (mechanical problems), an air carrier flight crew departed without performing post-maintenance walk-around. Aircraft failed to pressurize, due to an open equipment bay door.
