There have been a number of attempts to bring electronic ignition to the piston general aviation world—with varying rates of success. One we have been following is Electroair, a Howell, Michigan, company that developed an electronic ignition system (EIS) originally for homebuilts, and went on to get an STC for production airplanes—four-cylinder engine models first, then six-cylinder machines. It’s in the application process for turbocharged engines and may have that approval soon after this article appears.

Electroair has some 500 of its EIS in the field, and the owner feedback we got was uniformly positive (see sidebar).
