Background

    Engine manufacturers are developing and using various types of 
structural dynamic analysis methods to support both engine 
certification activities and aircraft manufacturers' certification 
activities. The FAA has developed policy to provide guidance for 
evaluating the use of structural dynamic analysis methods to show 
compliance with the requirements of Sec. 33.94 of Title 14 of the Code 
of Federal Regulations, ``Blade containment and rotor unbalance 
tests.'' This policy specifically addresses paragraph (a) of Sec. 33.94 
for engine design and configuration changes. This policy does not 
create any new requirements.

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