A B727-200 IN CLB AT 1500 FT DECLARED AN EMER AND RETURNED TO THE FIELD DUE TO THE AFT CARGO OPEN AND #3 ENG STALLING.

Narrative

PUSHBACK THROUGH TKOF WAS UNEVENTFUL COMPLETING ALL CHKLISTS IN A TIMELY MANNER. WE WERE CLRED INTO POS TO HOLD ON RWY 27 WAITING LNDG TFC FOR RWY 18R. AFTER TKOF AND JUST BEFORE 1500 FT; THE SO NOTED THE RAPID ASCENT OF CABIN PRESSURE. AT 1500 FT AGL THE THROTTLES WERE MOVED TO THE QUIET EPR AS THE CAPT LEVELED THE ACFT. UPON LEVELING; THE #3 ENG BEGAN WHAT APPEARED TO BE COMPRESSOR STALLS. WE REDUCED ENG #3 TO 1.4 EPR; WHICH ELIMINATED THE STALLS. THE CAPT XFERRED ACFT AND RADIO CTL TO ME AND BEGAN ASSESSING THE ENG AND PRESSURIZATION PROBS WITH THE SO. I REQUESTED STRAIGHT AHEAD FLT FROM AIR TFC. TURNING N; #3 ENG BEGAN COMPRESSOR STALLS AGAIN FOR WHICH WE MOVED THE THROTTLE TO IDLE AGAIN ELIMINATING THE COMPRESSOR STALLS. WE DETERMINED THE PROB WAS SERIOUS ENOUGH TO WARRANT RETURNING TO ZZZ. AS THE CAPT AND SO WORKED THE PROB; I INFORMED DEP CTL WE WOULD NEED VECTORS TO RETURN TO ZZZ REQUESTING MANEUVERING SPACE TO ALLOW US TIME TO DETERMINE THE EXTENT OF THE PROB AND IF FUEL DUMPING WOULD BE NECESSARY. NO EMER WAS DECLARED. AFTER SEVERAL MINS OF WORKING THE PROB; THE SO RECEIVED A CALL FROM THE FLT ATTENDANT WITH INFO FROM A PAX ABOUT THE APPEARANCE OF THE CARGO DOOR. NEAR THAT SAME TIME; BOTH THE CAPT AND SO OBSERVED THE AFT CARGO DOOR BECOMING ILLUMINATED. CHKLISTS WERE COMPLETED DEALING WITH THE ABNORMALS. AS A CREW; WE DETERMINED AN OVERWT LNDG ON ZZZ; LONGEST RWY WOULD BETTER SERVE THE SIT THAN DUMPING FUEL. CLB; DSCNT AND APCH CHKLIST WERE COMPLETED; ACFT CTL RETURNED TO THE CAPT AND AN UNEVENTFUL LNDG ON RWY 18R TAXI BACK TO THE GATE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED AFTER LEAVING THE GATE AND WAITING FOR CLRNC TO THE RWY THE COCKPIT CHK WAS ACCOMPLISHED WHICH INCLUDED THE DOOR WARNING INDICATIONS AND ALL DOORS INDICATED CLOSED AND LATCHED. THE RPTR SAID AT 1500 FT WHEN #3 ENG BEGAN STALLING ONLY THEN DID THE AFT CARGO DOOR LIGHT COME ON. THE RPTR STATED ON RETURN TO THE FIELD IT WAS FUND THE BARRIER NET WAS HANGING OUT; INNER DOOR SURFACE INSULATION WAS MISSING AND 1 SUITCASE WAS LOST. THE RPTR SAID THERE WAS NO EVIDENCE OF DAMAGE TO #3 ENG FAN BLADES. THE RPTR STATED MAINT WAS STARTING A FOD INGESTION CHK WHEN THE CREW LEFT FOR A PLANE CHANGE.
