Policy for Propeller Level Failure Effects; Policy for Bird 
Strike, Lightning, and Centrifugal Load Testing for Composite Propeller 
Blades

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of availability; policy statements.

-----------------------------------------------------------------------

SUMMARY: The Federal Aviation Administration (FAA) announces the 
availability of policy for propeller-level failure effects and policy 
for bird strike, lightning, and centrifugal load testing for composite 
propeller blades.

ANE-2001-35.31-R0 on March 12, 2003.

Background

    Many new propeller certification programs include composite blades 
and spinners and electronic controls. Part 35 of Title 14 of the Code 
of Federal Regulations (14 CFR part 35) does not have explicit safety 
standards for the substantiation of propellers with composite blades 
and spinners for bird strike, lightning strike, and centrifugal loads, 
nor does it address electronic controls and safety assessment. The 
safety standards for these design features and analyses have been 
incorporated into the propeller certification basis by issuing special 
conditions. Until rulemaking is finalized to incorporate these 
standards into part 35, individual propeller certifications that 
contain these novel or unusual design features must continue to be 
addressed with special conditions.
    Policy Statement Number ANE-2001-35.13-R0 provides guidance for the 
development of those special conditions with regard to propeller-level 
failure effects. Policy Statement Number ANE-2001-35.31-R0 provides 
guidance for structurally substantiating propellers with composite 
blades and spinners for bird strike, lightning strike, and centrifugal 
loads. These policies do not create any new requirement.

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

    Issued in Burlington, Massachusetts, on March 12, 2003.

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