Background

This AC provides guidance material for methods of complying with § 33.28, Electrical and Electronic Control (EEC) Systems. Initially, EEC technology was primarily applied to engines designed for large transport aircraft applications; the certification practice and implementation of § 33.28 was oriented toward these applications. When the use of EEC technology was limited to a small group of manufacturers, the information and guidance provided in the rule itself was adequate. However, because the use of EEC controls has spread, the need for additional advisory material has become evident in several recent engine certification programs.
