## Discrepancy

AIRCRAFT NLG WOULD NOT EXTEND.  ACFT PERFORMED A NOSE GEAR UP LANDING, WHICH RESULTED IN SUBSTANTIAL DAMAGE TO THE NOSE CONE, KEELS, FWD NOSE BULK HEAD AND BOTH NOSE GEAR DOORS.   A POST INCIDENT INSPECTION WAS PERFORMED AND THE RETRACTION LINKAGE WAS DETERMINED TO BE DRY AND LACKING LUBRICATION WHICH ALLOWED THE PIN TO MISS THE BELL CRANK ASSEMBLY.  THIS PREVENTED THE OPENING OF THE NOSE GEAR DOORS AND THE EXTENSION OF THE NOSE GEAR DESPITE ADEQUATE HYDRAULIC PRESSURE.
