## Discrepancy

APU SMOKE: ON FIRST START OF THE DAY WHEN APU BLEED WAS TURNED ON SMOKE CAME OUT OF THE AIR-CONDITIONING VENTS.    CHECKED OIL QUANTITY AND FOUND IT AT MAX PERFORMED BORESCOPE OF APU EXHAUST TURBINE AND FOUND OIL SWIRLS.   THIS IS COMMON WITH OVERSERWICING CONDITIONS AND WILL GET SMOKE OR STRONG ODOR UPON SHUTDOWN. DESERVICED APU OIL AND RESERVICED OIL TO APPROPIATE LEVEL. RETURNED APU TO NORMAL  CONFIGURATION, STARTED APU AND TURNED BLEED AIR ON. NO SMOKE OR SMELLS NOTED WORK PERFORMED PER CE680 AMM 49-10-15. PERFORMED TC-68A-21-181006M.
