Aviation Maintenance Practices covers workshop procedures and the daily skills required of the aviation maintenance technician, From tools and test equipment, to sheet metal work, to drawings, fits & clearances, to building wire harnesses; each topic is explained in step by step detail. You will learn by understanding concepts, not just rote memorization and you will learn how and why each skill is useful in the day-day tasks of the aircraft technician in an aviation maintenance environment.
This book is fully compliant as EASA Part 66 module 7 for the B1 license and has been given approvals by numerous EASA based civil aviation authorities.
