## Discrepancy

A MODERATE DIRTY SOCK ODOR IN THE COCKPIT AFTER TAKEOFF AND THROUGHOUT ENTIRE CLIMB.  LIGHTER INTENSITY DURING CRUISE, BUT PRESENT.  VERY STRONG DURING DESCENT,  ALL THE WAY TO TOUCHDOWN.  NOTICED IN FWD PART OF CABIN.  COCKPIT CREW USED OXYGEN.  INSPECTED APU AND ENGINES. NO OIL LEAKS.  DETERMINED SOURCE OF THE ODOR TO BE FROM THE NR 1 PACK.
