This is the newly revised edition of AC43.13 1B/2B. Includes Parts 1B & 2B with the latest changes for each and with corrections of dozens of numbering and pagination errors overlooked in other publisher's editions. The "bible" for A&Ps, IAs, aircraft owners, and homebuilders; this FAA Advisory Circular outlines the standards for acceptable methods, techniques, and practices for the inspection, repair and alteration of non-pressurized areas of civil aircraft with a gross weight of 12,500 lbs or less. Includes both Part 1B and Part 2B. This edition produced by Aircraft Technical Book Company is an exact page-by-page reproduction of the FAA advisory Circular just as offered by several other publishers, but with the following exceptions: ...It cost less. ...Its heavier duty coated gloss cover better resists dirt, damage, and normal wear. ...It corrects dozens of figure numbering and pagination errors overlooked in other editions. ...It's better looking - thanks to our friends at Lufthansa Technik.
