Jeppesen's Aviation Maintenance Handbook is a key resource for A&P technicians, homebuilders, pilots, and aircraft owners. Developed as a quick reference guide for the most common aviation technical information, it includes hundreds of references.
You will find a Mechanic's Handbook in practically every A&P technician's toolbox. and these Jeppesen and ASA books are by far the most popular. The difference between these is basically the amount of information presented and how it is organized. The ASA book is twice as thick and contains that much more information. The Jeppesen book limits itself to the more commonly used charts and graphs making what you do use often that much quicker to find. The choice is yours. Each is a tremendous value and an on-the-job time saver.
