What was found
EXCESSIVE UP AND DOWN MOVEMENT FOUND IN STEERING SECTION OF NOSE LANDING GEAR. BRONZE BUSHINGS FOUND TO BE WORN (P/N 532.20.12.078) IT IS BELIEVED THAT WHEN GREASING THE NOSE GEAR ASSEMBLY, THE CONTACT SURFACES OF THE BUSHINGS ARE NOT GETTING PROPER LUBRICATION BECAUSE THE SPLIT PINS THAT ARE USED TO RETAIN THE BUSHINGS ARE ALLOWING GREASE TO ESCAPE AND THEREFORE GREASE IS NOT GETTING BETWEEN THE SURFACES. PLUGGING THE HOLES IN THE SPLIT PINS MAY SOLVE THE PROBLEM BECAUSE THE GREASE WILL THEN BE FORCED UP TO THE BEARING CONTACT SURFACES.
