## Discrepancy

CREW REPORT ODOR IN AND AROUND 2L AND VIDEO CABIN AREA.  OPENED CABIN CEILING AT 2R&2L, RUN APU AND BOTH ENG WITH PACKS ON & GALLEY LOADED WITH OVEN, C-F MAKER, CHILLER, CABIN HEAT UP TO 85 DEGREE, CAP & F/O SHOULDER HEAT & FLIGHT DECK REST AREA HEATER.  COULD NOT DUPLICATED ODOR.  WAITING TO HEAR FROM SAMC FOR FURTHER DIRECTIVE.  ALSO CHECK F-DECK TEMP ORIFER, NO BLOCKAGE.  SUSPECT FORWARD UPPER RECIRCULATION FAN MAYBE POSSIBLE SOURCE OF ODOR FROM OVERHEAT.  CHANGED FAN AND BOTH FILTERS DUE TO ACRID SMELL IN COCKPIT AND CABIN.
