## Discrepancy

LANDING GEAR WOULD NOT COME DOWN, HAD TO DO A EMERGENCY EXTENSION.  IT WAS FOUND THAT THE RIGHT HYDRAULIC FILTER CANISTER HAD RUPTURED AT THE BASE OF THE THREADS CAUSING LOSS OF HYDRAULIC FLUID, A NEW HYDRAULIC FILTER HOUSING WAS INSTALLED AND THE ENTIRE HYDRAULIC SYSTEM TESTED SERVICEABLE.
