## Discrepancy

DURING DESCENT TO KLAN BOTH LEFT AND RIGHT HYDRAULIC PRESSURE LOW ANNUNCIATORS ILLUMINATED FOLLOWED BY LOSS OF HYDRAULIC PRESSURE.  THE PILOT PLACED THE LANDING GEAR HANDLE TO THE DOWN POSITION AND RECEIVED NO RESPONSE OF THE LANDING GEAR.  THE PILOT PERFORMED A MANUAL LANDING GEAR EXTENSION, DECLARED AN EMERGENCY AND LANDED WITHOUT INCIDENT IN KLAN.  MAINTENANCE INSPECTED THE AIRCRAFT AND FOUND THAT THE LEFT FLAP UP HYDRAULIC LINE P\N 27-81032-183 WAS CRACKED.  MAINTENANCE FABRICATED A REPLACEMENT LINE AND INSTALLED PER AMM 20-40-00 SECTION 1A-1E OPERATIONAL AND LEAK CHECKS WERE NORMAL. LEFT AND RIGHT ENGINE HYDRAULIC PUMPS REPLACED DUE TO LOSS OF PRESSURE LIMITS EXCEEDED.  HYDRAULIC SYSTEM FILTER'S INSPECTED NO DEFECTS FOUND
