Preface to the Seventh Edition
In preparing this edition, the authors reviewed FAR Parts 65 and 147, FAA-H-8083-30 & 31, AC 43.13-1B & 2B, and manufacturers and operators manuals and data to ensure that all required areas of study were included.
This revised edition updates material from the previous edition relating to aircraft structures and systems on current operational aircraft. Figures, charts, and photos have been updated to reflect new technology. The advanced composite materials chapter has been completely rewritten to reflect state-of-the-art maintenance and repair information and techniques for advanced composite structures used in modern aircraft. Advanced automated systems such as ECAM and EICAS are discussed in most chapters to reflect their operation relative to particular aircraft systems. The structures chapter has been expanded with multiple examples for the calculation of bend allowance and the setup of shop equipment. The hydraulics chapter has been expanded to include the 5000-psi hydraulic systems used in some new aircraft models. A discussion of a centralized fault display system (CFDS) has been added to the troubleshooting chapter.

Preface to the Sixth Edition
Aircraft Maintenance and Repair is designed to provide aviation students with the theoretical and practical knowledge required to qualify for certification as FAA airframe technicians in accordance with Federal Aviation Regulations (FARs). This text covers the subjects categorized in the FARs under Airframe Structures and Airframe Systems and Components and may be used as a study text in connection with classroom discussions, demonstrations, and practical application in the shop and on aircraft.
Aircraft Maintenance and Repair is one of five textbooks in the McGraw-Hill Aviation Technology Series. The other books in the series are
