Lycoming Overhauls
I received your 2013 Aviation Consumer Buyer’s Guide and was very interested in your article covering engine overhauls. One important fact I did not see is: Customers who are thinking about ordering a Lycoming factory overhauled engine need to know about Lycoming’s 36-year policy. If the customer’s engine left the Lycoming factory more than 36 years before the order date, Lycoming will not accept that engine for a factory overhaul.
It can only be used for core credit for a new or rebuilt engine.
Right now, 1977 is 36 years out, and 1977 through the early 1980s was one of the busiest times in history for aircraft production.
