    Background
    
        This advisory circular (AC) provides guidance and information on 
    acceptable methods, but not the only methods of compliance with 
    Sec. 33.14 of the Federal Aviation Regulations, title 14 of the Code of 
    Federal Regulations. Section 33.14 contains requirements of life 
    management requirements applicable to the design and life management of 
    titanium alloy high energy rotating parts of aircraft engines. Although 
    this AC does refer 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 advisory circular would be published under the authority 
    granted to the Administrator by 49 U.S.C. 106(g), 40113, 44701-44702, 
    44704 and would provide guidance for the requirements in 14 CFR part 
    33.
    
        Issued in Burlington, Massachusetts, on December 2, 1999.

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