This document outlines the most common repairs used on landing gear components. It is not the intention of this AIR to replace overhaul/component maintenance or technical order manuals@ but it can serve as a guide into their preparation. Refer to the applicable component drawings and specifications for surface finish@ thickness@ and repair processing requirements. This document may also be used as a guide to develop an MRB (Material Review Board) plan. The repairs in this document apply to components made of metallic alloys. These repairs are intended for new manufactured components and overhauled components@ including original equipment manufacturer (OEM)/depot and in-service repairs. The extent of repair allowed for new components as opposed to in-service components is left to the cognizant engineering authorities. Reference could be made to this document when justifying repairs on landing gears. For repairs outside the scope of this document@ a detailed justification is necessary. Landing gear repair is often a combination of several repair types defined herein. It must be understood that all the repairs listed in this document are not to be applied without the involvement of the cognizant engineer.
