#  Advisory Circular; Guidance Material For 14 CFR § 33.28, Reciprocating Engines, Electrical And Electronic Engine Control Systems

**AGENCY:**

Federal Aviation Administration, DOT

**ACTION:**

Notice of availability of advisory circular.

**SUMMARY:**

The Federal Aviation Administration (FAA) announces the availability of Advisory Circular (AC) Number 33.28-2, Guidance Material For 14 CFR 33.28, Reciprocating Engines, Electrical And Electronic Control Systems.

**DATES:**

The Engine and Propeller Directorate, Aircraft Certification Service, issued AC 33.28-2 on August 13, 2003.

**FOR FURTHER INFORMATION CONTACT:**

Mark Rumizen, Engine and Propeller Standards Staff, ANE-110, 12 New England Executive Park, Burlington, MA 0183-5299; telephone: (781) 238-7113; fax: (781) 238-7199; e-mail: *mark. [email protected].* The subject AC is available on the Internet at the following address: *http://www.airweb.faa.gov/rgl.*

**SUPPLEMENTARY INFORMATION:**

The FAA published a notice in the *Federal Register* on July 10, 2002 (67 FR 45780) to announce the availability of the proposed AC and invite interested parties to comment.

**Background**

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 compliance with § 33.28 that addresses these issues.

**Authority:**

49 U.S.C. 106(g), 40113, 44701-44702, 44704.

Issued in Burlington, Massachusetts, on August 13, 2003.

Marc J. Bouthillier,

Acting Manager, Engine and Propeller Directorate, Aircraft Certification Service.
