## Discrepancy

BETWEEN 8000-9000 FEET WE NOTICED A MILD CHEMICAL ODOR. I PERFORMED THE ELIMINATION OF ODOR/FUMES CHECLIST PER THE QRH. AFTER CALLING THE FA'S, I COULD NOT DETERMINE THE SOURCE AS THEY SMELLED IT IN THE CABIN ASWELL.-IAW TSM 05-50-00-810-831-A THE HIGHEST TOTALS WERE ON APU & BOTH PACKS. PERFORMED INSP OF APU IAW AMM 49-00-00-200-812 NO DEFECTS NOTED. ALSO PERFORMED DECONTAMINATION PROCEDURE IAW AMM 21-00-00-615-802. NO FUMES OR ODERS OBSERVED DURING DECONTAMINATION PRCEDURE. NO HISTORY IN OVER A MONTH OF ANY AQE. PLEASE REPORT FURTHER ISSUES. ACFT OK FOR SVC.
