AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD results from mandatory continuing
airworthiness information (MCAI) originated by an aviation authority of
another country to identify and correct an unsafe condition on an
aviation product. The MCAI describes the unsafe condition as:
Extension of airbrakes above 360 KIAS [knots indicated air
speed]/0.79 Mi [Mach indicated] results in aerodynamic
driven vibration of the airbrake which, if not limited per Revision
14 to the AFM [airplane flight manual], can lead to high cycle
fatigue failure of the airbrake in-board hinge.
The unsafe condition is high cycle fatigue of the airbrake in-board
hinge, which can result in loss of the airbrake, which in turn can lead
to reduced controllability of the airplane. We are issuing this AD to
require actions to correct the unsafe condition on these products.
DATES: This AD becomes effective October 28, 2010.
ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of
Transportation, Docket Operations, M-30, West Building Ground Floor,

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on June 25, 2010 (75 FR
36296). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
Extension of airbrakes above 360 KIAS [knots indicated air
speed]/0.79 Mi [Mach indicated] results in aerodynamic
driven vibration of the airbrake which, if not limited per Revision
14 to the AFM [airplane flight manual], can lead to high cycle
fatigue failure of the airbrake in-board hinge.
The unsafe condition is high cycle fatigue of the airbrake in-board
hinge, which can result in loss of the airbrake, which in turn can lead
to reduced controllability of the airplane. The required action
includes revising the Limitations section of the Gulfstream 200
Airplane Flight Manual to prohibit deploying the air brakes above the
stated speed. You may obtain further information by examining the MCAI
in the AD docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the
[[Page 57845]]
public interest require adopting the AD as proposed.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect about 90 products of U.S.
registry. We also estimate that it will take about 1 work-hour per
product to comply with the basic requirements of this AD. The average
labor rate is $85 per work-hour. Based on these figures, we estimate
the cost of this AD to the U.S. operators to be $7,650, or $85 per
product.
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 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 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 regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.
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 the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone (800) 647-5527) is in the
ADDRESSES section. Comments will be available in the AD docket shortly
after receipt.
