B757-200 CREW NEGLECTED TO REVIEW LOGBOOK PRIOR TO DEP AND LEFT WITH OPEN ITEM.

Narrative

THIS RPT DETAILS A COCKPIT CREW ERROR WHICH RESULTED IN AN ACFT OPERATING WITH AN OPEN LOGBOOK MAINT DISCREPANCY. THE SAME CREW OPERATED THIS ACFT FROM ATL TO LGA AND BACK TO ATL. DURING THE ATL-LGA SEGMENT; THE CREW WAS MADE AWARE OF AN INTERMITTENT PROB CAUSING ONE OF THE CABIN LAVATORIES NOT TO FLUSH. THE CREW RPTED THIS TO OUR COMPANY VIA ACARS AND MADE THE REQUIRED LOGBOOK ENTRY. WHILE ON THE GND AT LGA; MAINT PERSONNEL NEVER ADDRESSED THE OPEN LOGBOOK DISCREPANCY. PRIOR TO DEP FOR ATL; A COMBINATION OF DISTRS AND A BREAKDOWN IN COMS BTWN THE CAPT AND FO LEFT EACH OF US THINKING THE OTHER HAD REVIEWED THE LOGBOOK WHEN; IN FACT; THE LAVATORY DISCREPANCY WAS STILL OUTSTANDING. THIS ERROR WAS DISCOVERED ENRTE TO ATL WHEN ADDITIONAL DISCREPANCIES WERE ENTERED INTO THE LOG. ON ARR AT ATL; MAINT PERSONNEL WERE ADVISED OF THE OPEN ITEMS AND ALL WERE EITHER CORRECTED OR DEFERRED BEFORE THE NEXT FLT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE ELECTRONIC CENTRAL ACFT MONITORING (ECAM) INDICATION RECEIVED BY THE COCKPIT CREW WAS PROBABLY INHIBITED DURING TKOF AND INITIAL CLB PER SYSTEM DESIGN. THE DOOR IS NORMALLY CLOSED BY THE STATION AGENT FROM THE OUTSIDE; BUT SHOULD BE CHECKED BY THE CABIN CREW PRIOR TO DEP. IN FLIGHT INSPECTION BY THE CAPT SHOWED THAT THE WINDOW PROVIDED FOR OBSERVING LOCKED DOOR LATCHES ALL SHOWED UNLOCK UNTIL THE HANDLE WAS MOVED TOWARD THE LOCKED POSITION. THE HANDLE COULD NOT BE FULLY STOWED IN THE LOCKED POSITION. A 1/8 INCH OUT OF LOCKED POS ON THE HANDLE WAS AS FAR AS IT WOULD GO; BUT INSPECTION WINDOW SHOWED LOCKED AND THE ECAM WARNING WAS EXTINGUISHED. MAINT INSPECTED THE DOOR. IT WAS FOUND TO BE WITHIN SPECIFICATIONS AND NO ADJUSTMENTS WERE MADE. THE MECHANISMS WERE CLEANED; LUBRICATED AND TESTED. THE DOOR OPERATED NORMALLY WITH THE HANDLE IN ITS PROPER POS WHEN CLOSED. THE SUBSEQUENT DEP AND FLT WAS NORMAL. THE RPTR SUSPECTS THERE MAY HAVE BEEN A BUILDUP OF DIRT OR DEBRIS THAT PREVENTED FULL CLOSURE OF THE LOCKING MECHANISM THAT WAS REMOVED DURING MAINT ACTION.
