## Discrepancy

DURING APPROACH, LG DID NOT EXTEND AFTER PILOT SELECTED LG HANDLE DOWN.  TRIED TO CYCLE GEAR HANDLE WITH THE SAME RESULTS.  NOTIFIED CONTROL TOWER OF THE LG MALFUNCTION, PERFORMED MANUAL EXTENSION OF LG.  AFTER EXTENSION PILOT RECEIVED THREE GREEN DOWN & LOCKED INDICATOR LIGHTS & LANDED WITHOUT FURTHER INCIDENT.  INSPECTION REVEALS A HOLE IN HYD PRESS LINE, PN 40818-00 FOR HYD ENG PUMP PRESS LINE, BEHIND FIREWALL IN RT NACELLE.  R & R HYD LINE, ALSO CHANGED BOTH LT & RT HYD FILTERS & BOTH HYD PUMPS.  OPERATIONAL CHECKS OF HYD SYS WERE NORMAL.
