Aviation Maintenance Technician Handbook–Powerplant (FAAH808332A) Volume 2
Aviation Maintenance Technician Handbook–Powerplant (FAAH808332A) Volume 2 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. Since the knowledge requirements for the airframe and powerplant ratings closely parallel each other in some subject areas, the chapters which discuss fire protection systems and electrical systems contain some material which is also duplicated in the Aviation Maintenance Technician Handbook–Airframe (FAAH808331A). 
Aviation Maintenance Technician Handbook–Powerplant Volume 1
The Aviation Maintenance Technician Handbook–Powerplant (FAAH808332A) is one of a series of three handbooks for persons preparing for certification as a powerplant mechanic. It is intended that this handbook provide the basic information on principles, fundamentals, and technical procedures in the subject matter areas relating to the powerplant rating.
