Narrative:
Inadequate preflight by engineer. This was a cargo aircraft with 2 jumpseats in cockpit and 2 jumpseats located in entry vestibule. All jumpseats were occupied. Upon arrival at destination, the captain (only out of habit) tried to turn off the courier oxygen and bleed the system, only to find that the seats in the vestibule had an oxygen system that was deferred. We checked the log, and found no mention of the deferral. The aircraft had just returned to service after extensive maintenance (90 days plus), and apparently all references regarding the oxygen system being disconnected were inadvertently deleted from the log. While the jumpseaters were all pilots, and should have preflted their own oxygen system, the captain felt that responsibility fell to the flight engineer. Hopefully, everyone involved will be more aware.

Title: HVT FRT ACFT DEPARTS WITH PLT PAX ON BOARD WITH AN INOP OXYGEN SYS IN VIOLATION OF FARS. ACFT MAINT DISCREPANCY DISCOVERED IN POSTFLT INSPECTION.
Narrative: INADEQUATE PREFLT BY ENGINEER. THIS WAS A CARGO ACFT WITH 2 JUMPSEATS IN COCKPIT AND 2 JUMPSEATS LOCATED IN ENTRY VESTIBULE. ALL JUMPSEATS WERE OCCUPIED. UPON ARR AT DEST, THE CAPT (ONLY OUT OF HABIT) TRIED TO TURN OFF THE COURIER OXYGEN AND BLEED THE SYS, ONLY TO FIND THAT THE SEATS IN THE VESTIBULE HAD AN OXYGEN SYS THAT WAS DEFERRED. WE CHKED THE LOG, AND FOUND NO MENTION OF THE DEFERRAL. THE ACFT HAD JUST RETURNED TO SVC AFTER EXTENSIVE MAINT (90 DAYS PLUS), AND APPARENTLY ALL REFS REGARDING THE OXYGEN SYS BEING DISCONNECTED WERE INADVERTENTLY DELETED FROM THE LOG. WHILE THE JUMPSEATERS WERE ALL PLTS, AND SHOULD HAVE PREFLTED THEIR OWN OXYGEN SYS, THE CAPT FELT THAT RESPONSIBILITY FELL TO THE FLT ENGINEER. HOPEFULLY, EVERYONE INVOLVED WILL BE MORE AWARE.
