## Discrepancy

AFTER TAKEOFF, RECEIVED AN EXTREME AIR NOISE FOR ABOUT 20 SECONDS,  MUCH MORE THEN JUST PACK HIGH FLOW.   AT THE SAME TIME, THE F/A'S REPORTED A ELECTRICAL BURNING ODOR IN FORWARD GALLEY,  ODOR WENT AWAY AS SOON AS FLOW STOPPED.  IAW FAULT ISOLATION MANUAL, PERFORMED AMM PAGE BLOCK 21-23-07/801 AND INSPECTED ALL DUCTS SURROUNDING THE FORWARD GALLEY CABIN CEILING,  CABIN FLOOR AND FOUND NO LEAKS OR ABNORMAL ISSUES.   OPERATED PACKS AND FOUND NO ISSUES AT THIS TIME.
