What responsibility and it is ar happens? They pull it and check another reconditioned one out of the supply channels. Now they can't just leave a big expensive landing gear laying around so it is shipped to Hill AFB where it is made better than new. Upon receipt at Hill, the gear goes to Examination ar d Evaluation Section of the Strut shop where they take it apart and clean it to determine just what needs to be done to put the gear back in top condition. h because important employs many base person io and it is basic to the flying ul Air Force planes. The responsibility is that of one--bot- repairing gear, landing including such big ones as the or bigger yet the 2 or C-1- 41 B-5- C-- 5. It all begins when a maintenance crew somewhere in the Air Force finds a main gear with a landing malfunction that r--X is They check for tolerances, for cracks and for malfunctioning not j N ' parts. From there, it goes through various shops where the different parts worked and reworked. The shops include the machine shop, the plating shop, the grinding shop and the welding shop. Different parts receive varing processes such as being refaced, stripped of chrome, rechromed, ground, tempered, baked, inspected, peened, flame plated, cadium sprayed, Shot peen is a metal finishing operation in which small steelshot is hurled at high velocity against a piece of metal. It can be hurled by either centrifugal force or air blast. The impact plastically deforms the surface to a depth of a few thousands of an inch, process, using the flame of an oxyacetylene torch. This fusing technic is the major difference between the ground again, honed and new installed. bushings Two interesting processes flame spray process and conventional metalizing the performed parts of the landing gear are the flame spraying and the shot peen. Flame Spraying is a method of applying hard surfacing alloys such as nickel or cobalt in the form of a finely divided metal powder. The powder deposit is fused to the base metal in a second step in the on some of procedures. The whenever used is process improved resistance to wear corrosion or galling is used. It is better than in high grade tool-di- e a residue stress. Thus the metal more producing compressive making resistant to fai igue failure and the surface hardening steels. It is particularly effective on cylinders. The final step is usually a finishing slightly. grind.
