This advisory circular (AC) provides guidance and acceptable methods, but not the only methods, that may be used to demonstrate compliance with the new bird ingestion requirements § 33.76 of the Federal Aviation Regulations, Title 14 of the Code of Federal Regulations. These new standards were published in the Federal Register on September 14, 2000 (65 FR 66848) and became effective on December 13, 2000. Although this AC refers to regulatory requirements that are mandatory, this AC is not, in itself, mandatory. This AC neither changes 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 AC provides information and guidance that address Federal Aviation Administration (FAA) type certification standards for aircraft turbine engines with regard to bird ingestion. The requirements of § 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 requirements.
