Background

    This draft advisory circular (AC) provides guidance and acceptable 
methods, but not the only methods, that may be used to demonstrate 
compliance with the bird ingestion requirements of Sec. 33.76 of the 
Federal Regulations, Title 14 of the Code of Federal Regulations once 
that regulation becomes final. A proposal to amend the Federal Aviation 
Regulations by adding a new section, Sec. 33.76, was published in the 
Federal Register on December 11, 1998 (64 FR 68635). Although this 
draft AC does refer to regulatory requirements that would be mandatory, 
this draft AC is not, in itself, mandatory. This AC would neither 
change any regulatory requirements nor authorizes changes in or 
deviations from the regulatory requirements.
    This effort was adopted as a part 33 and Joint Aviation Regulations 
for engines (JAR-E) harmonization project and was selected as an 
Aviation Rulemaking Advisory Committee (ARAC) project. This draft AC 
provides information and guidance that addresses Federal Aviation 
Administration (FAA) type certification standards for aircraft turbine 
engines with regard to bird ingestion. The requirements under 
Sec. 33.76 reflect recent analysis of the bird threat encountered in 
service by turbine engine powered aircraft.
    This advisory circular, published under the authority granted to 
the Administrator by 49 U.S.C. 106(g), 40113, 44701-44702, 44704, 
provides guidance for these proposed requirements.

    Issued in Burlington, Massachusetts, on April 12, 2000.
Thomas A. Boudreau,
Acting Manager, Engine and Propeller Directorate, Aircraft 
Certification Service.
