Parts suppliers catalogs The Standard Aircraft Handbook for Mechanics and Technicians is presented in shop terms for the mechanics and technicians engaged in building, maintaining, overhauling, and repairing all-metal aircraft. It is also useful for the student mechanic, who must acquire the basic mechanical skills fundamental to every technical specialty. Although this handbook is "tool-box size," it is a relatively complete guide to all basic shop practices, such as the use of basic tools, drilling, riveting, sheet-metal forming, use of threaded fasteners and installation of plumbing, cables and electrical wiring. Additional practical information is presented on aerospace materials and standard parts. Chapters on non-destructive testing (NDT) and corrosion detection and control provide a guide to advanced technology inspection and detection equipment, techniques, and procedures. The information presented in this handbook was obtained from techniques and procedures developed by various aircraft and equipment manufacturers and are in general compliance with manufacturing specifications. This handbook is not intended to replace, substitute for, or supersede any FAA regulations, shop and quality-control standards of an aircraft manufacturer, repair station, or the manufacturer's maintenance manuals. CRAFTSMANSHIP There is no substitute for craftsmanship! Regardless of the amount of engineering, planning, or design that might go into an aircraft, the ultimate quality of that aircraft depends upon those who build and maintain it.
