The E-113 was a small flat-twin piston engine developed by Aeronca for use in some of their light aircraft. It was an overhead valve development of the flathead configuration E-107.
Originally fitted with a single ignition system, this was uprated to dual ignition when changes in FAA regulations made this mandatory in 1939. By that time, however, both the engine and the aircraft that it powered were facing obsolescence. Altogether, some 1,800 examples were built. Following an incident in October 2015 where the propeller detached from an Aeronca C3 in 2015, the Light Aircraft Association has issued an advisory that all aircraft fitted with these engines have the crankshaft attachment inspected prior to flying again. This issue has been recognised since 1939.
