Powerplant

The Powerplant section is designed for persons preparing for certification as a powerplant mechanic. It is intended that this section provide the basic information on principles, fundamentals, and technical procedures in the subject matter areas relating to the powerplant rating. It is designed to aid students enrolled in a formal course of instruction, as well as the individual who is studying on his or her own.

This section contains an explanation of the units that make up each of the systems that bring fuel, air, and ignition together in an aircraft engine for combustion. There are so many different types of aircraft in use today, it is reasonable to expect that differences exist in airframe components and systems. To avoid undue repetition, the practice of using representative systems and units is carried out throughout the section. Subject matter treatment is from a generalized point of view and should be supplemented by reference to manufacturer's manuals or other textbooks if more detail is desired. This section is not intended to replace, substitute for, or supersede official regulations or the manufacturer’s instructions.
