Narrative:

We were scheduled to fly and flew 2 legs, ord-dca and dca-ord using B727 aircraft 'X.' approximately 10 mins prior to landing on our second leg into ord, the flight engineer noticed that we had the wrong logbook (aircraft 'Y'). Upon landing at ord, the aircraft was down until its logbook was found and placed on board. Some interesting facts: 1) our WX briefing message had aircraft 'X' maintain history. 2) the last page in the logbook onboard (aircraft 'Y') had maintenance history for aircraft 'X.' 3) maintenance was done on aircraft 'X' at dca, a logbook entry was completed (in aircraft 'Y's logbook) and a new release was submitted for aircraft 'X.' many people missed the fact that they had a wrong logbook onboard, including the crew that flew before us on aircraft 'X' and the crews that flew aircraft 'Y' that day. Safety of flight was never an issue as we had 2 releases on and sufficient maintenance history due to the air carrier's maintenance tracking system, which is computerized.

Title: A B727 ACR FLC DISCOVERED, WHILE INFLT, THAT THE LOGBOOK ON BOARD BELONGED TO A DIFFERENT ACFT. HOWEVER, SOME OF THE LOGBOOK DATA AND AT LEAST ONE OF THE PAGES WAS FOR THE ACFT THAT THEY WERE FLYING. SOME OTHER FLCS HAD FLOWN THE SAME ACFT IN THE PAST WITHOUT NOTING THIS PROB. MAINT PERSONNEL HAD MIXED UP THE PAGES AND THE LOGBOOKS AND THEY, LATER, CORRECTED THE ERROR. SEE ACN 371245.

Narrative: WE WERE SCHEDULED TO FLY AND FLEW 2 LEGS, ORD-DCA AND DCA-ORD USING B727 ACFT 'X.' APPROX 10 MINS PRIOR TO LNDG ON OUR SECOND LEG INTO ORD, THE FE NOTICED THAT WE HAD THE WRONG LOGBOOK (ACFT 'Y'). UPON LNDG AT ORD, THE ACFT WAS DOWN UNTIL ITS LOGBOOK WAS FOUND AND PLACED ON BOARD. SOME INTERESTING FACTS: 1) OUR WX BRIEFING MESSAGE HAD ACFT 'X' MAINTAIN HISTORY. 2) THE LAST PAGE IN THE LOGBOOK ONBOARD (ACFT 'Y') HAD MAINT HISTORY FOR ACFT 'X.' 3) MAINT WAS DONE ON ACFT 'X' AT DCA, A LOGBOOK ENTRY WAS COMPLETED (IN ACFT 'Y'S LOGBOOK) AND A NEW RELEASE WAS SUBMITTED FOR ACFT 'X.' MANY PEOPLE MISSED THE FACT THAT THEY HAD A WRONG LOGBOOK ONBOARD, INCLUDING THE CREW THAT FLEW BEFORE US ON ACFT 'X' AND THE CREWS THAT FLEW ACFT 'Y' THAT DAY. SAFETY OF FLT WAS NEVER AN ISSUE AS WE HAD 2 RELEASES ON AND SUFFICIENT MAINT HISTORY DUE TO THE ACR'S MAINT TRACKING SYS, WHICH IS COMPUTERIZED.
