Narrative:

Inbound had one inoperative placard on the F/east panel. It stated that #2 hi-stage pneu supply was inoperative, use lo-stage only. We operated the flight jfk-lax using #2 lo-stage pneu. On descent, #2 pneu was turned off and written up in the logbook. Lax maintenance noted that in reviewing the logbook, that #2 pack temperature indicator was previously inoperative and that #2 pneu system should not be used. They feel that FAA logbook review may consider this as use of an inoperative system. There were 3 inoperative and #2 pack inoperative in automatic. There were no placards that stated #2 pneu was unusable! We checked the placards against our MEL and found no restrictions other than 'use #2 lo-stage' and 'operate #2 pack in manual.' on preflight our crew reviewed the logbook and MEL. Jfk maintenance also did same. If #2 pneu system was not usable, it should have been placarded, 'do not pressurize, except engine start.' if #2 pack was inoperative it should have been placarded inoperative. This whole thing sounds like a matter of interpretation. We would not use an inoperative system. We would not be dumb enough to write up a malfunction of an inoperative system.

Title: FLT CRW OF WDB INTERPRETED LOGBOOK WRITE UP AS PERMISSIVE FOR FLT. UPON REACHING DESTINATION, MAINTENANCE PERSONNEL CONSIDERED THE WRITE UP PROHIBITIVE FOR FLT.

Narrative: INBND HAD ONE INOP PLACARD ON THE F/E PANEL. IT STATED THAT #2 HI-STAGE PNEU SUPPLY WAS INOP, USE LO-STAGE ONLY. WE OPERATED THE FLT JFK-LAX USING #2 LO-STAGE PNEU. ON DSCNT, #2 PNEU WAS TURNED OFF AND WRITTEN UP IN THE LOGBOOK. LAX MAINT NOTED THAT IN REVIEWING THE LOGBOOK, THAT #2 PACK TEMP INDICATOR WAS PREVIOUSLY INOP AND THAT #2 PNEU SYS SHOULD NOT BE USED. THEY FEEL THAT FAA LOGBOOK REVIEW MAY CONSIDER THIS AS USE OF AN INOP SYS. THERE WERE 3 INOP AND #2 PACK INOP IN AUTO. THERE WERE NO PLACARDS THAT STATED #2 PNEU WAS UNUSABLE! WE CHKED THE PLACARDS AGAINST OUR MEL AND FOUND NO RESTRICTIONS OTHER THAN 'USE #2 LO-STAGE' AND 'OPERATE #2 PACK IN MANUAL.' ON PREFLT OUR CREW REVIEWED THE LOGBOOK AND MEL. JFK MAINT ALSO DID SAME. IF #2 PNEU SYS WAS NOT USABLE, IT SHOULD HAVE BEEN PLACARDED, 'DO NOT PRESSURIZE, EXCEPT ENG START.' IF #2 PACK WAS INOP IT SHOULD HAVE BEEN PLACARDED INOP. THIS WHOLE THING SOUNDS LIKE A MATTER OF INTERPRETATION. WE WOULD NOT USE AN INOP SYS. WE WOULD NOT BE DUMB ENOUGH TO WRITE UP A MALFUNCTION OF AN INOP SYS.
