The most current general aviation textbook available. Written to the new FAR part 147 standards. Expanded to include a complete section on electrical generators and motors, new hardware, and nonmetallic components. Many new tables, charts, and illustrations, including: abrasives, corrosion removal and treatment, corrosion points, helicopter weight and balance, and others. It was totally overhauled in early 2009 to include the workbook within the text.
