[Docket No. NE128; Notice No. 35-06-01-SC]


Special Conditions: McCauley Propeller Systems, Model Propeller 
3D15C1401/C80MWX-X

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed special conditions, withdrawal.

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

SUMMARY: The FAA is withdrawing a previously published notice that 
proposed special conditions for McCauley Propeller Systems for model 
propeller 3D15C1401/C80MWX-X. We are withdrawing the notice in response 
to McCauley Propeller Systems notification to cancel the application 
for certification.

SUPPLEMENTARY INFORMATION: 

Background

    On August 2, 2006, the FAA published a notice of proposed special 
conditions, Notice No. 35-06-01-SC, for McCauley Propeller Systems for 
model propeller 3D15C1401/C80MWX-X (71 FR 43674). On November 29, 2004, 
McCauley Propeller applied for type certification for a new model 
3D15C1401/C80MWX-X propeller. The model propeller 3D15C1401/C80MWX-X 
has novel or unusual design features when compared to the state of 
technology described in the airworthiness standards under part 35. The 
design feature uses blades that are constructed of composite material. 
The blade has a carbon fiber spar, a shell composed of braided carbon 
fiber and fiberglass, and metallic leading edge erosion protection to 
give the material strength properties and durability. The material 
properties depend on the carbon fiber and fiberglass lay-up and the 
resin matrix material that bind the blade together. Composite materials 
introduce fatigue characteristics and failure modes that differ from 
metallic materials. The proposed special conditions pertain to the 
effects of novel or unusual design features such as effects on the 
structural performance of the propellers. We requested comments on 
these proposed special conditions by September 1, 2006.

Reason for Withdraw

    We are withdrawing Notice No. 35-06-01-SC because McCauley 
Propeller Systems canceled the application for certification.

Conclusion

    Withdrawal of Notice No. 35-06-01-SC does not preclude the FAA from

issuing another notice on the subject matter in the future or 
committing the agency to any future course of action. Issued in 
Burlington, Massachusetts on March 5, 2010.
