Description

Sooner or later, almost all pilots will experience some sort of engine abnormality while operating their aircraft. Even minor problems, if not dealt with properly, can progress quickly into very expensive and serious issues. This book is designed to let you diagnose a wide variety of engine troubles, ranging from common issues like running a little bit rough or being hard to start, up through major events like power losses and fires. This guide lists the symptoms observed in the cockpit and suggests their likely causes, in enough detail to help you and your mechanic target the likely problem area and save valuable time and money. In addition, Englert has described the systems and provided schematics that will help you better understand how your engine works, providing a background for better engine operation and highlighting common problems. While most four-stroke engines are quite similar and the descriptions and principles apply to most of them, this book also highlights issues specific to various engines including Lycoming, Continental, Rotax, Jabiru and Volkswagens. This is a must-read book for pilots of piston-powered aircraft.
