The Aviation Maintenance Technician Handbook-General (FAA-H-8083-30A)(released in 2018) is the latest revision developed by the Federal Aviation Administration (FAA) as one of a series of three handbooks for persons preparing for the certification exams required for obtaining an Aviation Maintenance Technician (AMT) certificate with Airframe or Powerplant rating or both (FAA A&P license). It is intended that this handbook 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. The handbook is designed to aid students enrolled in a formal course of instruction preparing for FAA certification as a maintenance technician as well as for current technicians who wish to improve their knowledge. This volume contains information on mathematics, aircraft drawings, weight and balance, aircraft materials, processes and tools, physics, electricity, inspection, ground operations, and FAA regulations governing the certification and work of maintenance technicians. New to this volume is a section addressing how successful aviation maintenance technicians incorporate knowledge and awareness of ethics, professionalism and human factors in the field. The companion handbooks to Aviation Maintenance Technician Handbook-General (FAA-H-8083-30A) are the Aviation Maintenance Technician Handbook-Airframe (FAA-H-8083-31A, Vol 1 and Vol 2), and the Aviation Maintenance Technician Handbook-Powerplant (FAA-H-8083-32A, Vol 1 and Vol 2).
