John Schwaner 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 and construction 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.


  • * Diagnosing engine failures
  • * engine operation
  • * how metal fatigue affects engine life
  • * torsional engine vibrations and engine balance
  • * flow porting and its effect on engine performance
  • * lubrication and wear in your engine
  • * an engineering approach to cylinder repair
  • * and more

Reader Review
I am a retired Floatplane Pilot from the 70's. During my employement at Stikine Air, we purchased all of our engines from Sacramento Sky Ranch. We NEVER had an engine failure in 16 yrs of operation. I am constantly amazed at the rate of engine problems by some other local Air Taxis. Cylinders cracking, and numerous other problems. They run WOT/LPO ALL the time. We operated 180's & 185 floatplanes and Amphibs. WE left cowl flaps open all the time, and reduced power soon after lift off. We climbed flat, and at flew at low altitudes. This seems to be contrary to articles I have read in Flying,AOPA,Private Pilot magazines. Mr. Schwaner seems to be the most knowledgable person I have ever heard about, and appreciate His work.
Thank You,

This book goes beyond most dry text books and tells you WHY engines operate the way they do and why they fail and how to prevent such failures! Many chapters from lubrication to proper torque setting on fasteners to identifying the cause of different types of engine and component failure. The book is worth the price for the illustrations alone. John Schwaner is that rare type of man that not only has a vast knowledge of his subject but, the ability to explain and transfer that knowledge to the average person. Buy this book, read it and keep a copy in your toolbox on the shop floor.

  This has the most info on aircraft engines that I have found. This has been my bible for engine rebuilding and repair. I have not found anything to compare it against as it goes into complete analysis of each part. Very highly recommended. more...
