## Discrepancy

COCKPIT ODOR: AFTER TAKEOFF AND BLEED AIR TRANSFER WE NOTICED A MUSTY SMELL IN THE AIR-CONDITIONING SYSTEM.  INSPECTED ACM SYSTEM WITH NO DEFECTS NOTED. REMOVED WATER SOCKS, FOUND THEM DIRTY AND TO HAVE ODOR. REINSTALLED SOCKS,. RAN APU, AND BOITH ENGINES. SWAPPED BETWEEN THE THREE BLEED SYSTEMS WITH THE SAME ODOR NOTED IN THE SOCKS PRESENT REGARDLESS OF WHICH BLEED SOURCE WAS USED. PLACED SOCKS ON ORDER. REF CL 650 AMM 21-51-13. REPLACED BOTH CONDENSOR BAGS IN REF TO CL-650AMM 21-51-13. OPS, LEAK AND SMELL CHECK GOOD.
