[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
[[Page 13239]]
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.

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