Background

    This AC provides guidance material for methods of complying with 
Sec. 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 Sec. 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.
