The current class is 2 weeks and the instructor is top notch with lots of experience in General Aviation, Experimental, and Lycoming factory. The first week is all classroom with the exception of a Lycoming factory tour. The tour was yesterday and very informative. If you are a motor person, you will like this class. Our class has some who are IA's, a couple of A&P's, several pilots, and a couple of folks who are building or flying experimental aircraft. One guys is building a RV-10 and another building a Panther. Its amazing to see the impact the experimental sector is having on all aspects of aviation.
Starting in Feb 2019, the class will only be one week. The mornings will be classroom, the afternoons will be lab work on engines (disassembly / assembly).
Want to know more about your Lycoming engine? Then this is the ticket. If you are an IA, then this class qualifies as recurrent training.
