Background

    This AC is on the subjects of turbine engine windmilling and rotor 
locking tests that were identified as areas where differences existed 
between the Joint Aviation Requirements-Engines, and part 33 of the 
Federal Aviation Regulations. A study group composed of representatives 
of the Federal Aviation Administration, the Joint Aviation Authorities, 
Transport Canada and the Aviation Industry worked to produce a set of 
improved and harmonized requirements. These requirements have been 
published as a notice of proposed rulemaking in the Federal Register on 
March 6, 1995.
    This advisory circular, published under the authority granted to 
the Administrator by 49 U.S.C. 106(g), 49 U.S.C. App. 1354(a), 1421 and 
1423, provides guidance for these proposed requirements.

    Issued in Burlington, Massachusetts, on April 7, 1995.
James C. Jones,
Acting Manager, Engine and Propeller Directorate, Aircraft 
Certification Service.
