Aeronca E-113

From Wikipedia, the free encyclopedia

The E-113 was a small flat-2 piston engine developed by Aeronca for use in some of their light aircraft. It was a development of the 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.
