John Schwaner of Sacramento Sky Ranch explains the piston aircraft engine with a practical day to day approach but directed towards the operator and repair personnel.Sky Ranch Engine Manual thoroughly covers the operation, inspection, and maintenance of the Lycoming and Continental piston aircraft engine, including a very comprehensive troubleshooting guide. This book goes beyond the basic theory of aircraft reciprocating engines but instead focuses on the practical aspects for mechanics and operators of why things go bad, how to repair them, and most important; how to keep them from failing in the first place.
