## Discrepancy

THE PILOT REPORTED THAT BOTH LT & RT HYD FAILURE LIGHTS ILLUMINATED, WHILE THE HYD PRESS GAUGE WAS FLUCTUATING. UNABLE TO EXTEND THE FLAPS PAST THE ¼ POSITION.  WHEN THE PILOT PUT THE GEAR HANDLE TO THE DOWN POSITION THE LG DID NOT EXTEND & THE HYD SYS PRESS GAUGE INDICATED ZERO.  THE PILOT PERFORMED A MANUAL GEAR EXTENSION IAW AMF PROCEDURES & RECEIVED A LG DOWN & LOCKED INDICATION.  THE ACFT LANDED WITHOUT INCIDENT.  TROUBLE SHOOTING REVEALED A LEAKING FLAP UP HYD LINE PN 27-81006-029 IN LT WW.  REPLACED THE FLAP UP HYD LINE WITH A NEW FABRICATED LINE IAW AMM.  PERFORMED FLAP SYS LEAK & OPERATIONAL CHECKS, ALL CHECKS WERE SATISFACTORY.
