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 such as ATA codes, tubing and wiring color codes, conversion tables, physics formulas, aircraft marshalling signals, tool identification and use guidelines, hardware tables, sheet metal bend allowances and setback tables, aircraft drawing symbols, wire assembly graphs and color codes, fluid lines and fitting charts, torque tables, weight and balance formulas, and hardware identification.
