Hi Tom,
sorry to correct you, aircraft use a lot of split ring lock washers, and I mean a lot!
I have over four decades of avionics experience behind me. There are many places on modern aircraft where they are not used, even more places where they should not be used (some units and antenna that come with mounting hardware are likely to use them). Interestingly, terminal strips in our 1941 Curtiss C46 Commando used fibre lock nuts, while decades newer aircraft may have terminal strips with plain nuts, flat washers, and split ring washers. Many electrical contactors use plain nuts with split ring washers, take a look at the alternator, master contactor, or starter contactor on an aircraft.

You wont find any of those split lock washers on airplanes or aircraft engines, because they are useless. They mainly use elliptical offset nuts, often called jet nuts or aircraft nuts. The Nylock nuts are very good for moderate temperature applications.
