## Discrepancy

INTERMITTENT METALLIC ACIDIC SMELL IN THE COCKPIT DURING CLIMB OUT AND AGAIN DURNING DESCENT. NOT NOTICED IN THE CABIN. SEEMED TO BE LOCALIZED TO THE COCKPIT.   UPON ARRIVAL TO AIRCRAFT NO SMELL WAS NOTED, SPOKE WITH CREW AND THEY STATED THAT IT WAS A SMELL SIMILAR TO NAIL POLISH REMOVER. DUE TO SMELL BEING NOTED ONLY IN THE COCKPIT PERFORMED GVI OF FWD AVIONICS BAY AND NOTED NOTHING OUT OF THE ORDINARY AND DID NOT NOTICE ANY UNUSUAL SMELLS. INSPECTED BATTERY 1 AND FOUND NO ABNORMALITIES AND BOTH BATTERIES ARE READING TEMPS IN NORMAL RANGES. RAN AIRCRAFT ONLY ON PACK 1 FOR 10 MINUTES AND COULD NOT DUPLICATE ANY UNUSUAL SMELLS. RAN BOTH ENGINES AND BOTH PACKS ON WITH CREW WITH APU BLEED OFF AND COULD NOT DUPLICATE THE SMELL, NO SIMILAR HISTORY NOTED A/C OKAY FOR CONTINUED SERVICE.
