## Discrepancy

AIRCRAFT ON APPROACH TO FPO, CREW SELECTED GEAR DOWN.  THE MLG INDICATED DOWN AND LOCKED AND THE NLG INDICATED UNSAFE. MAINTENANCE INSPECTED THE NLG AND FOUND THE SECONDARY STRUT NOT TO BE FULLY LOCKED, GEAR SAFETY PIN COULD NOT BE INSTALLED.  THE SAFETY PIN BUSHING ON THE LINK ROD HAD MIGRATED INTERFERING WITH THE SECONDARY STRUT.
