Flight Crew Overcame Equipment Problem
Aircraft
Shortly after takeoff we experienced a dirty sock/fume event that was isolated only in the flight deck. Both myself and the First Officer put on our oxygen mask to abate the smell. The odor dissipated within 15 minutes of departure. Upon descent the dirty sock smell came back this time more prominent. We tried to isolate the smell by using the odor isolation procedure in the Flight Crew Operations Manuel with no help in getting the dirty sock smell to dissipate. The odor was first only in the flight deck on descent but then spread throughout the cabin.
A320 Captain reported a fume event during initial climb which dissipated shortly after departure. The odor returned more intensely during descent. Flight crew completed the Flight Crew Operations Manual procedure which produced negative results.
