Description

This handbook for Aviation Mechanics, Aviation Maintenance Technicians schools (AMT), repair stations, aircraft owners, and homebuilders details the standards for acceptable methods, techniques, and practices for the inspection, repair, and alteration of aircraft. It is a compilation of the two most important Advisory Circulars (ACs) written by the Federal Aviation Administration (FAA) on this topic—namely, Acceptable Methods, Techniques, and Practices—Aircraft Inspection and Repair (AC 43.13-1B) and Acceptable Methods, Techniques, and Practices—Aircraft Alterations (AC 43.13-2B), which are key references for the Aviation Mechanic FAA Knowledge Exams. AC 43.13-1B provides details on the materials and practices, health and safety, inspection, repair, and finishes for wood structures, fabric covering, fiberglass and plastics, and metal structures, welding and brazing. It includes chapters dedicated to nondestructive inspection (NDI), corrosion, inspection and protection, aircraft hardware, control cables and turnbuckles, engines, fuel, exhaust, propellers, aircraft systems and components, weight and balance, electrical systems, avionics, and human factors. AC 43.13-2B is a manual filled with details and instructions for the installation of aircraft components and systems, such as communications, navigation, and emergency systems, anti-collision and supplementary lights, skis, oxygen systems in non-pressurized aircraft, rotorcraft external-load devices, cargo slings and extern
