The Aviation Maintenance–General section is designed for persons preparing for mechanic certification with airframe or powerplant ratings, or both. It is intended that this section will provide basic information on principles, fundamentals, and technical procedures in the subject matter areas common to both the airframe and powerplant ratings. Emphasis in this volume is on theory and methods of application.
Because there are so many different types of airframes and powerplants in use today, it is reasonable to expect that differences exist in the components and systems of each. To avoid undue repetition, the practice of using representative systems and units is implemented throughout the site. Subject matter treatment is from a generalized point of view, and should be supplemented by reference to manufacturers’ manuals or other textbooks if more detail is desired. This section is not intended to replace, substitute for, or supersede official regulations or the manufacturers’ instructions.
