## Discrepancy

AT THE CONCLUSION OF ALL WORK ON APU AND AIR CONDITIONING SYSTEM ACTIVATE THE BLEED ON #2 ENGINE AND PERFORM NORMAL ENGINE START USING APU FOR BOTH ENGINES. RUN ENGINES SEPARATELY AT POWER LEV ELS SIMILAR TO TEST 8 PER AMM 71-00-00-725-008-N00 FOR 5 MINUTES WITH PACKS ON WHILE ISOLATING THE BLEEDS FROM LEFT TO RIGHT CHE CKING FOR ABNORMAL SMELLS IN THE CABIN OR FLIGHT DECK.
