## Discrepancy

ETOPS SIGNIFICANT SYSTEM, APU WOULD NOT RE-START ON GROUND.  FAULT LIGHT INDICATION, EICAS INDICATES LOW APU OIL.  VISUALLY INSPECTED APU FOR LEAKS, NONE NOTED.  FOUND APU BLEED SWITCH IN ON POSITION.  STARTED APU SUCCESSFULLY ON 1ST ATTEMPT.  APU OIL INDICATES FULL.  APU FUNCTIONS NORMALLY, OK FOR SERVICE.
