14 CFR Part 39
[Docket No. FAA-2007-29176; Directorate Identifier 2007-NE-38-AD;
Amendment 39-16365; AD 2010-14-20]

Airworthiness Directives; McCauley Propeller Systems Model
4HFR34C653/L106FA Propellers
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
McCauley Propeller Systems model 4HFR34C653/L106FA propellers. This AD
requires a onetime fluorescent penetrant inspection (FPI) and eddy
current inspection (ECI) of the propeller hub for cracks. This AD
results from reports of 10 hubs found cracked during propeller
overhaul. We are issuing this AD to prevent failure of the propeller
hub, which could cause blade separation, damage to the airplane, and
loss of control of the airplane.
DATES: This AD becomes effective August 17, 2010. The Director of the
Federal Register approved the incorporation by reference of certain
publications listed in the regulations as of August 17, 2010.
ADDRESSES: You can get the service information identified in this AD
from McCauley Propeller Systems, P.O. Box 7704, Wichita, KS 67277-7704;
telephone (800) 621-7767.
The Docket Operations office is located at Docket Management
Facility, U.S. Department of Transportation, 1200 New Jersey Avenue,
SE., West Building Ground Floor, Room W12-140, Washington, DC 20590-
0001.
FOR FURTHER INFORMATION CONTACT: Jeff Janusz, Aerospace Engineer,
Wichita Aircraft Certification Office, FAA, Small Airplane Directorate,

telephone (316) 946-4148; fax (316) 946-4107.
SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39
with a proposed AD. The proposed AD applies to McCauley Propeller
Systems model 4HFR34C653/L106FA propellers. We published the proposed
AD in the Federal Register on September 28, 2007 (72 FR 55120). We also
published a supplemental proposed AD in the Federal Register on April
13, 2010 (75 FR 18774). Those actions proposed to require a onetime FPI
and ECI of the propeller hub for cracks.
Examining the AD Docket
You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains this AD, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone (800) 647-5527) is provided in
the
[[Page 39802]]
ADDRESSES section. Comments will be available in the AD docket shortly
after receipt.
Comments
We provided the public the opportunity to participate in the
development of this AD. We received one comment on the original
proposed AD, which we responded to in the supplemental proposed AD. We
received no comments on the supplemental proposed AD, or on the
determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.
Costs of Compliance
We estimate that this AD will affect 128 propellers installed on
airplanes of U.S. registry. We also estimate that it will take about
41.5 work-hours per propeller to perform the actions, and that the
average labor rate is $85 per work-hour. Based on these figures, we
estimate the total cost of the AD to U.S. operators to be $451,520.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, Section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
We have determined that this AD will not have federalism
implications under Executive Order 13132. This AD will not have a
substantial direct effect on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866;
(2) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
We prepared a summary of the costs to comply with this AD and
placed it in the AD Docket. You may get a copy of this summary at the
address listed under ADDRESSES.
