## Discrepancy

AIRCRAFT EXPERIENCED LOSS OF HYDRAULIC PRESSURE DURING DESCENT INTO SALINA FOR ROUTINE FUEL STOP.  IMMEDIATELY RE-ROUTED TO LINCOLN FOR MAINTENANCE.  BLEW GEAR DOWN USING EMERGENCY SYSTEM.  WAS ABLE TO EXTEND FLAPS PARTIALLY.  USED EMERGENCY BRAKING FOR LANDING.  UPON INVESTIGATION, FOUND HYDRAULIC LINE IN AFT MAINTENANCE HOLE CHAFED THROUGH (REFERERENCE BULLETIN FIGURE 1 ITEM 3), BUT WAS NOT HOLDING TUBE PROPERLY AWAY FROM STRUCTURE ON LEFT SIDE OF AFT MAINTENANCE BAY.  RECOMMEND INSPECTION OF THIS AREA FOR PROPER CLEARANCE.
