Narrative:

After takeoff roc, aircraft would not pressurize. It was obvious that all air conditioning and pressurization systems were operating normally and that a 'hole' existed in the airplane. I elected for an immediate return to roc. We found door 2R was closed in a cocked position. The cams on the leading edge of the door had not engaged their proper slots. The door warning light was not on in spite of this condition. Had local mechanic inspect door for damage, etc, and clear log with concurrence of our maintenance folks in sfo. As we had a dual fuel load to start and still had 4.5 over minimum fuel load for the leg, we took off again about 1 hour late. However, I failed to contact dispatch personally for a rerelease, which made dispatch unhappy and rightfully so. I was busily involved in clearing the log and just assumed that dispatch was informed by others in the company. A complicating factor was that our ACARS system failed to report our landing and block times back in roc, thus dispatch was not aware of the event until after we were airborne the second time. This is a good reminder that after any event, the first person to contact is dispatch because of their joint responsibility for the flight.

Title: FLT CREW OF MLG UNABLE TO PRESSURIZE ACFT AFTER TKOF. RETURNED, LANDED. ACARS DID NOT ADVISE DISPATCH. FLT TOOK OFF AFTER MAINTENANCE FAILING TO OBTAIN RERELEASE. COMPANY AND FAA POLICY.

Narrative: AFTER TKOF ROC, ACFT WOULD NOT PRESSURIZE. IT WAS OBVIOUS THAT ALL AIR CONDITIONING AND PRESSURIZATION SYSTEMS WERE OPERATING NORMALLY AND THAT A 'HOLE' EXISTED IN THE AIRPLANE. I ELECTED FOR AN IMMEDIATE RETURN TO ROC. WE FOUND DOOR 2R WAS CLOSED IN A COCKED POSITION. THE CAMS ON THE LEADING EDGE OF THE DOOR HAD NOT ENGAGED THEIR PROPER SLOTS. THE DOOR WARNING LIGHT WAS NOT ON IN SPITE OF THIS CONDITION. HAD LOCAL MECHANIC INSPECT DOOR FOR DAMAGE, ETC, AND CLEAR LOG WITH CONCURRENCE OF OUR MAINT FOLKS IN SFO. AS WE HAD A DUAL FUEL LOAD TO START AND STILL HAD 4.5 OVER MINIMUM FUEL LOAD FOR THE LEG, WE TOOK OFF AGAIN ABOUT 1 HR LATE. HOWEVER, I FAILED TO CONTACT DISPATCH PERSONALLY FOR A RERELEASE, WHICH MADE DISPATCH UNHAPPY AND RIGHTFULLY SO. I WAS BUSILY INVOLVED IN CLEARING THE LOG AND JUST ASSUMED THAT DISPATCH WAS INFORMED BY OTHERS IN THE COMPANY. A COMPLICATING FACTOR WAS THAT OUR ACARS SYSTEM FAILED TO REPORT OUR LNDG AND BLOCK TIMES BACK IN ROC, THUS DISPATCH WAS NOT AWARE OF THE EVENT UNTIL AFTER WE WERE AIRBORNE THE SECOND TIME. THIS IS A GOOD REMINDER THAT AFTER ANY EVENT, THE FIRST PERSON TO CONTACT IS DISPATCH BECAUSE OF THEIR JOINT RESPONSIBILITY FOR THE FLT.
