Design and development

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 a J-99 variant Aeronca C3, 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 was first recognised in 1939.[1][2]
