The school provided a translator so he could follow the course, despite the fact that it was taught in English, a language he did not share. All rights reserved. Build Team; Charlie. TCM Continental and even the older Pratt and Whitney radials also go full rich on takeoff. We stock a range of Lycoming engines for exchange from Lycoming O-235 to O-360 & TIO-540 engines and as well as a warehouse of Lycoming parts and accessories at the ready. Lycoming had 60 variations of the O-320 engine and nearly all of them were interchangeable—except the -H model engines. As each component is covered in turn, the class goes into not only the manufacturing process, but the maintenance procedures related to it, the problems that might be encountered in the life of the component, and various tips and tricks that will help maintain and get the longest life out of the component. We are providing this price change information to allow you to make buying decisions and place orders, … In a Lycoming engine, the camshaft is located above the crankshaft at the top of the engine. According to Doebler, there has been talk of going all electronic for most of Lycoming’s documentation for years, but so far that hasn’t happened, and that means that paper documents are still handy to have around. This hardening only penetrates the parent metal by 20 or 30 thousandths of an inch. 8. “Our new instructor, Mike Damiani, lives and breathes everything aviation. With Thunderbolt engines, customers get a genuine Lycoming engine that is factory built, factory tested and supported - with several popular options of fuel systems, ignition systems, performance enhancements and finishing options.

Doebler stepped through the history of the oil pump and how Lycoming engineers took a tried-and-true product and attempted to make it less expensive to manufacture. Crankcase: Magnaflux and Ultrasonic … For those with the old cylindrical oil screens instead of a replaceable filter, the screen has a soldered seam that is designed to rupture if the screen becomes clogged. Fortunately, for newer engines produced since the last service bulletin issued in September 1995, it should not be an issue.

Less than that, you can button things up and run it some more. One refreshing thing about the class is that Lycoming is not afraid to talk about their own mistakes. The first thing that students do when they arrive is to fill out an order form that entitles them to a complete set of Lycoming service letters, bulletins, and instructions—to be sent to their home or business. Relevant service documents are introduced for the students to study for further information, and Doebler concludes each segment with real-world stories of issues he (and other service reps) have encountered over the years. Doebler’s descriptions of how individual components are manufactured and how the various machining and plating processes are performed gives one a better understanding of why parts are shaped the way they are, and more importantly, why some surfaces can be re-machined and others are hardened or coated in a way that they cannot be re-done. Cirrus is not known for being a major player in training, but a year ago, it announced the new TRAC version of... © 2020 Aviation Publishing Group. How can I decode Lycoming engine number suffices? Both are held in the comfortable classrooms of the technical college located at the Williamsport Airport (KIPT), a couple of miles east of downtown. … There is no carburetted version of the engine, which would have been designated O-390 and therefore the base model is the IO-390.

As Lycoming frequently points out, the Experimental world does not have the same legal requirement for maintenance to factory standards—but the engine itself doesn’t know if it is installed in a certified or Experimental aircraft, so good judgment means that instructions and directives from the factory should always be considered by homebuilders when maintaining their engines. The kit pricing used to make this a viable way for a buyer with no core engine to arrive at an essentially new, assembled engine. With an undisclosed compression ratio (we’d guess in the 8.8-9.0:1 range), the spec … Sun May 31, 2009 3:46 pm #750371.

But it is evident that every employee in the factory knows the critical nature of what these engines will do, and care is put into every step. They build upon the standard non-certified engines and include a rotating system balanced to within 0.5 gram (connecting rods, pistons, piston pins), ported and polished cylinders and customized paint options. When they crank the engine until they get oil pressure, oil is pumped into the lifter galleys and cam bearings, but not directly onto the cam/lifter interface. It’s a good thing that they aren’t expected to carry them home; the classroom versions occupy two 6-inch thick binders and weigh in at an impressive poundage. The Lycoming Team.

Located in central Pennsylvania, just a little ways upstream from Lock Haven (the traditional home of Piper Aircraft), the name is pronounced by locals as “Lycumming”—a bit strange to this long-time aviator’s ear, but not unpleasant at all. The school, run cooperatively by Lycoming Engines and the Pennsylvania College of Technology, is well known as the place to go for mechanics, pilots, and anyone else who needs to know the intricacies of the gray powerplants that hang on the noses and nacelles of so many airplanes. The Service class is designed to teach students as much as they can learn about how Lycoming engines are designed, manufactured, and maintained. Not surprisingly, most stories have happy endings, as Lycoming has always stepped up and fixed issues faced by customers around the globe. Once registration paperwork was out of the way, Doebler dove straight into the course material, first talking about—the paperwork. Many of the manufacturing processes are designed to produce extremely hard or wear-resistant components that should last through several overhaul periods, so long as foreign objects are not allowed to wear them away. The overhaul was performed at MMS Aviation in Coshocton, Ohio as part of my apprenticeship. We had several A&P mechanics, an FBO owner who maintains a fleet of aircraft, an instructor for an A&P school on the West Coast, several homebuilders with varying levels of experience, and a Peruvian Air Force mechanic who wanted direct factory training to help him maintain a fleet of aircraft with various Lycoming engines. Van’s Aircraft kit builders are the largest group of Thunderbolt customers because the Lycoming IO-390 is the engine of choice for the newest RV–14 kit airplane. The town of Williamsport, Pennsylvania, is located near a stream that the indigenous Lenape people called Legani-hanne, which means “sandy stream.” The name was later spoken and recorded by European settlers as Lycaumick, and that morphed into a word known by many generations of pilots—Lycoming.
