![]() ![]() Cut the patch plate from material of the same thickness as the original or the next greater thickness, allowing an edge distance of 21⁄2 rivet diameters. Lay out the new rivet row with a transverse pitch of approximately five rivet diameters and stagger the rivets with those put in by the manufacturer. For relief of stresses at the corners of the trim-out, round them to a minimum radius of ½-inch. Trim out the damaged portion to the allowances mentioned in the preceding paragraphs. The procedures for making all three types of panel repairs are similar. The repair procedure for the other edges of the damage follows the previously explained methods. Inside the MemberFor damage that, after being trimmed, has less than 81⁄2 manufacturer’s rivet diameters of material inside the members, use a patch that extends over the members and an extra row of rivets along the outside of the members.Įdges of the PanelFor damage that extends to the edge of a panel, use only one row of rivets along the panel edge, unless the manufacturer used more than one row. Outside the MemberFor damage that, after being trimmed, has 81⁄2 rivet diameters or more of material, extend the patch to include the manufacturer’s row of rivets and add an extra row inside the members. The particular type of repair required depends on whether the damage is repairable outside the member, inside the member, or to the edges of the panel. Where a section of skin is damaged to such an extent that it is impossible to install a standard skin repair, a special type of repair is necessary. A panel section is the part of a panel between adjacent stringers and bulk heads. ![]() In aircraft construction, a panel is any single sheet of metal covering. ![]() NOTE: Blind rivets should not be used on floats or amphibian hulls below the water line. Inspection of floats and hulls involves examination for damage due to corrosion, collision with other objects, hard landings, and other conditions that may lead to failure. If the necessary information is not found in the SRM, attempt to find a similar repair or assembly installed by the manufacturer of the aircraft.įloatsTo maintain the float in an airworthy condition, periodic and frequent inspections should be made because of the rapidity of corrosion on metal parts, particularly when the aircraft is operated in salt water. Any additional knowledge needed to make a repair is also detailed. Normally, a similar repair is illustrated, and the types of material, rivets, and rivet spacing and the methods and procedures to be used are listed. When repairing a damaged component or part, consult the applicable section of the manufacturer’s SRM for the aircraft. This section describes typical repairs of the major structural parts of an airplane. ![]()
