## Discrepancy

SMOKE COMING FROM APU TAILPIPE ON SHUTDOWN.  MAINTENANCE FOUND APU OIL LEVEL LOW AND OIL IN TAIL PIPE.  MAINTENANCE FOUND THE OIL LEAK FROM STARTER PAD DUE TO A MISSING O-RING ON THE STARTER WHICH RESULTED IN THE REPLACEMENT OF THE STARTER IAW AMM 49-42-51.  A SATISFACTORY OPS CHECK WAS ACCOMPLISHED.  IAW AALA 201607119004 WHICH REPLACED THE APU.
