Amendment 39-15865; AD 2009-07-06]
RIN 2120-AA64
Airworthiness Directives; Hamilton Sundstrand Propellers Model
568F Propellers
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
Hamilton Sundstrand Propellers model 568F propellers with certain part
number (P/N) and serial number (SN) blades. This AD requires removing
affected propeller blades from service for rework. This AD results from
reports of blades with corrosion pits in the tulip area of the blades.
We are issuing this AD to prevent cracks from developing in the tulip
area of the blade, which could result in separation of the blade and
loss of airplane control.
DATES: This AD becomes effective May 1, 2009.
We must receive any comments on this AD by May 26, 2009.

SUPPLEMENTARY INFORMATION: We have received reports of corrosion on six
propeller blades. A lack of adhesive and primer beyond the end of the
compression wrap during manufacturing of certain serial-numbered
propeller blades could result in corrosion pits developing in the tulip
area of the propeller blade. This condition, if not corrected, could
cause cracks in the tulip area, which could result in separation of the
propeller blade and possible loss of airplane control.
FAA's Determination and Requirements of This AD
Although no airplanes that are registered in the United States use
these propellers, the possibility exists that the propellers could be
used on airplanes that are registered in the United States in the
future. The unsafe condition described previously is likely to exist or
develop on other Hamilton Sundstrand Propellers model 568F propellers
of the same type design. We are issuing this AD to prevent cracks from
developing in the tulip area of the blade, which could result in
separation of the blade and loss of airplane control. This AD requires
removing from service, Hamilton Sundstrand Propellers model 568F
propellers, with a P/N and SN listed in Table 1 of this AD, within 30
days after the effective date of this AD.
FAA's Determination of the Effective Date
Since no domestic operators use this product, notice and
opportunity for public comment before issuing this AD are unnecessary.
Therefore, we are adopting this regulation immediately.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment; however, we invite you to send us any written relevant data,
views, or arguments regarding this AD. Send your comments to an address
listed under ADDRESSES. Include ``AD Docket No. FAA-2009-0270;
Directorate Identifier 2008-NE-30-AD'' in the subject line of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the rule that might
suggest a need to modify it.
We will post all comments we receive, without change, to http://
www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact
with FAA personnel concerning this AD. Using the search function of the
Web site, anyone can find and read the comments in any of our dockets,
including, if provided, the name of the individual who sent the comment
(or signed the comment on behalf of an association, business, labor
union, etc.). You may review the DOT's complete Privacy Act Statement
in the Federal Register published on April 11, 2000 (65 FR 19477-78).
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 the same as
the Mail address provided in the ADDRESSES section. Comments will be
available in the AD docket shortly after receipt.
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 the 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.
