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:
The airbrake upper crossbeam on an airplane failed in-flight.
The crossbeam failure caused damage to the rudder control system,
resulting in loss of rudder control. Loss of rudder control will
cause handling difficulties particularly during take-off, approach,
and landing phases in cross winds.
* * * * *
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective September 22, 2009.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of September 22,
2009.

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 11, 2009 (74 FR
27725). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
The airbrake upper crossbeam on an airplane failed in-flight.
The crossbeam failure caused damage to the rudder control system,
resulting in loss of rudder control. Loss of rudder control will
cause handling difficulties particularly during take-off, approach,
and landing phases in cross winds.
BAE Systems (Operations) Ltd has published Inspection Service
Bulletin (ISB) 53-200 that revises and supersedes the inspection
requirements, which are defined in the Maintenance Review Board
Report (MRBR) SSI Task 53-40-125, Supplemental Structural
Inspections Document (SSID) Tasks 53-40-125.1 and 53-40-125.2
(included in the Airworthiness Limitations Section of Aircraft
Maintenance Manual Chapter 5 that is currently mandated as part of
EASA AD 2007-0271 [which corresponds to an FAA NPRM, Directorate
Identifier 2007-NM-363-AD]) and in Maintenance Planning Document
(MPD) Task Reference 534025-DVI-10000-1. These revised inspection
requirements and reduced inspection periods are to ensure that any
fatigue damage is detected before it causes upper airbrake crossbeam
failure. MRBR, SSID and MPD will be amended in due course to reflect
these revised inspection periods.
For the reasons stated above, this Airworthiness Directive (AD)
requires the [high frequency eddy current and low frequency phase
analysis eddy current] inspection [for cracking, discrete surface
damage, and discontinuity (corrosion and mechanical damage)] and, as
necessary, repair of the airbrake upper crossbeam.
The required actions include replacing the three rivets with Hi-lok
pins. For cracking, damage, or discontinuity that is outside certain
limits defined in the service bulletin, the repair includes contacting
BAE Systems (Operations) Limited for repair instructions and doing the
repair. 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 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 affects 1 product of U.S. registry. We
also estimate that it takes about 6 work-hours per product to comply
with the basic requirements of this AD. The average labor rate is $80
per work-hour. Based on these figures, we estimate the cost of this AD
to the U.S. operators to be $480 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
[[Page 41606]]
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.

Maintenance Manual Chapter 5 that is currently mandated as part of
EASA AD 2007-0271 [which corresponds to an FAA NPRM, Directorate
Identifier 2007-NM-363-AD]) and in Maintenance Planning Document
(MPD) Task Reference 534025-DVI-10000-1. These revised inspection
requirements and reduced inspection periods are to ensure that any
fatigue damage is detected before it causes upper airbrake crossbeam
failure. MRBR, SSID and MPD will be amended in due course to reflect
these revised inspection periods.
For the reasons stated above, this Airworthiness Directive (AD)
requires the [high frequency eddy current and a low frequency phase
analysis eddy current] inspection [for cracking, discrete surface
damage, and discontinuity (corrosion and mechanical damage)] and, as
necessary, repair of the airbrake upper crossbeam.
