Table of contents Volume 2: Chapter 10: Aircraft Systems Chapter 11: Communication & Navigation Chapter 12: Hydraulic & Pneumatic Power Systems Chapter 13: Aircraft Landing Gear Systems Chapter 14: Aircraft Fuel Systems Chapter 15: Ice & Rain Protection Chapter 16: Cabin Environmental Control Systems Chapter 17: Fire Protection Systems Glossary Index The Aviation Maintenance Technician Handbook- Airframe (FAA-H-8083-31B) is one of a series of three handbooks for persons preparing for certification as an airframe or powerplant mechanic. This handbook provides basic information on principles, fundamentals, and technical procedures in the subject matter areas relating to the airframe rating. It is designed to aid AMT students enrolled in a formal course of instruction, as well as the individual who is studying on their own. Since the knowledge requirements for the airframe and powerplant ratings closely parallel each other in some subject areas, the chapters which discuss fire protection systems and electrical systems contain some material that is also duplicated in the Aviation Maintenance Technician Handbook - Powerplant (FAA-H-8083-32B). This AMT handbook contains information on airframe construction features, assembly and rigging, fabric covering, structural repairs, and aircraft welding. The handbook also contains an explanation of the units that make up the various airframe systems. Because there are so many different types of aircraft in use today, it is reasonable to expect that differences exist in airframe components and systems. To avoid undue repetition, the practice of using representative systems and units is carried out throughout the handbook. Subject matter treatment
