Description

This updated book encompasses two Advisory Circulars: AC 43.13-1B, Change 1 (9/27/2001) (Acceptable Methods, Techniques, and Practices – Aircraft Inspection and Repair) and AC 43.13-2B (3/3/2008) (Acceptable Methods, Techniques, and Practices – Aircraft Alterations). This is a “must have” book for anyone involved in the construction or maintenance of aircraft. This book covers the FAA-recommended procedures for most aircraft maintenance tasks as well as many construction techniques including wood, fabric, and metalwork. While some of the newer techniques have yet to be included (T-88 or the Stits covering process, for example) there is a real wealth of information here about FAA-acceptable methods for inspection and repair (and by extension, amateur-built aircraft construction.) AC 43.13-1B with Change 1 covers aircraft inspection and repair practices and techniques. AC 43.13-2B covers acceptable methods and practices for making alterations to aircraft (field approvals). Note that AC 43.13-2B supercedes the previous version, AC 43.13-2A (1/1/1977), which is now cancelled.

Written by the FAA, Updated through 2008 (Public Domain/Not Copyrighted). ISBN-13: 978-0-9774896-9-5. Published by FAA and Aircraft Technical Book Company. 834 Pages, Softcover.
