## Discrepancy

FAS TOLD US NEAR TOD  THAT THERE WAS A STRANGE CHEMICAL TYPE ODOR  AFTER T/O, NOW FL SICK, FLT CREW REPORTS THAT MAINTENANCE WAS DONE TO RT PACK IN DALLAS. FLT CREW ALSO REPORTS THAT DURING FULL POWER FOR TAKE OFF, ODOR STARTED TO OCCUR. CREW REPORTS THAT AROUND 10,000 FT, ABOUT 15 MINUTES AFTER TAKE OFF ODOR STARTED TO DISSIPATE AND DID NOT COME BACK. SPOKE WITH FLIGHT CREW AFTER LANDING ABOUT ODOR. BASED ON FLIGHT CREW REPORTS, ODOR IS FROM THE CABIN, NOT THE PACK. PERFORMED OPS CHECK OF BOTH PACKS AND NO DEFECTS WERE FOUND. FOUND SOUR ODOR IN AFT CABIN NEAR AFT LAV. NO OTHER PROBLEMS, SOUNDS OR ODOR FOUND IN AIRCRAFT.
