## Discrepancy

DURING FINAL APPROACH, FLAP POSITION INDICATED 25 DEGREES AND NEVER MOVED WHEN FLAPS WERE SELECTED TO 40 DEGREES.  EXECUTED GO-AROUND AND FLAPS MOVED SLOWLY, BUT DID ACHIEVE 40 DEGREES ON SECOND ATTEMPT AND A SUCCESSFUL LANDING WAS ACCOMPLISHED.  MAINTENANCE FOUND HYDRAULIC LINE IN FORWARD CARGO AREA LEAKING THROUGH PIN HOLE.  REPLACED LINE AND THE LEAK AND OPERATIONAL CHECK OF FLAP SYSTEM WAS NORMAL.
