## Discrepancy

ON CLIMB-OUT FROM MIA, NR 1 OIL QTY STARTED TO DECREASE RAPIDLY.  DID A PRECAUTIONARY ENG SHUTDOWN OF NR 1 ENGINE FOR OIL QTY LOSS.  RETURNED TO AIRFIELD, LANDING NORMAL.  MAINTENANCE INSPECTED NR 1 ENG AND FOUND OIL TANK CAP NOT IN CLOSE POSITION.  SERVICED ENGINE TO PROPER AMOUNT AS REQUIRED.  RESECURED ENGINE TANK OIL CAP.  RUN UP CHECK ACCOMPLISHED, NO LEAKS NOTED, ENGINE OP'S CHECK GOOD.  AIRCRAFT RETURNED TO SERVICE.
