Electrical and Electronic Engine Control (EEC) technology was initially applied to turbine engines designed for large transport aircraft applications. Therefore, the information and guidance for showing compliance with § 33.28 provided by the FAA was oriented toward these applications. However, the increasing use of EEC systems in reciprocating piston engines has created a need for guidance specifically for reciprocating engines. This AC provides a means, but not the only means, of showing compliance with § 33.28 that addresses these issues.
