## Discrepancy

ON TAKEOFF, A STRONG, DISTINCT ODOR WAS NOTICED AND LASTED THROUGHOUT THE FLIGHT. IT SMELLED LIKE BURNING WET LOCKER ROOM SOX AND NOW OUR CLOTHES HAVE THAT SAME ODOR.  IN MY PAST, THIS WAS FOUND TO BE A BAD ACM SHAFT SEAL. CORRECTIVE ACTION: PERFORMED SERVICE LETTER LS_CL300_01 S REV 0. OPS CHECK GOOD. IAW AMM 21-00-00
