What was found

ON APPROACH, LANDING GEAR WOULD NOT COME DOWN USING THE GEAR HANDLE. USED ALTERNATE LANDING GEAR EXTENSION METHOD 1, NORMAL EXTENSION WAS TRIED SEVERAL TIMES, BUT GEAR HANDLE WAS INEFFECTIVE. INSPECTED AIRCRAFT AND FOUND SAFE FOR FERRY FLIGHT FROM GEG TO PDX. IN PDX, REPLACED RESISTOR AT TERMINAL BLOCK 7 BETWEEN 8C AND 9G, AND REPLACED LANDING GEAR SELECTOR VALVE. OPERATIONAL AND FUNCTIONAL CHECK OF GEAR IS GOOD.
