Airworthiness Directives; BAE Systems (Operations) Limited Model

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:
Three events have been reported where insulation material was
found to be fouling pulleys in the aileron interconnect circuit in
the cabin roof area. * * *
Interference between the cable and the insulation bag causes the
material to be drawn into the gap between the pulley and the pulley
guard. This condition, if not detected and corrected, could lead to
restricted aileron movement and consequently, reduced control of the
aeroplane.
* * * * *
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective October 7, 2010.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of October 7,
2010.

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 May 19, 2010 (75 FR
27959). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
Three events have been reported where insulation material was
found to be fouling pulleys in the aileron interconnect circuit in
the cabin roof area. The insulation material is contained in a bag,
the material of which tends to become brittle with age. During the
production life of the aeroplane type, several methods of bag
retention were applied, all of which involved puncturing the bag.
This puncture tends to result in a tear, which, if detected in time,
can be repaired with tape; however, the affected cabin roof area is
not frequently accessed for inspection. Over time, the weight of the
bag also tends to cause tears in the material, making the insulation
material sag, thereby causing interference with the cable and
pulley.
Interference between the cable and the insulation bag causes the
material to be drawn into the gap between the pulley and the pulley
guard. This condition, if not detected and corrected, could lead to
restricted aileron movement and consequently, reduced control of the
aeroplane.
For the reasons described above, this [EASA] AD requires the
installation of additional guards, bolts and nuts on the aileron
interconnect cable pulleys at frame 29 (left and right).
This [EASA] AD has been revised to exclude aeroplanes from the
Applicability that have been modified to freighter configuration in
accordance with BAE Systems modification No. HCM50200B. As this
modification includes the removal of the insulation bags, the unsafe
condition that is addressed by this [EASA] AD cannot exist or
develop on those aeroplanes.
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
[[Page 53856]]
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 1 product of U.S. registry. We
also estimate that it will take about 5 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Required parts will cost about $340 per product.
Where the service information lists required parts costs that are
covered under warranty, we have assumed that there will be no charge
for these parts. As we do not control warranty coverage for affected
parties, some parties may incur costs higher than estimated here. Based
on these figures, we estimate the cost of this AD to the U.S. operator
to be $765.
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.

Effective Date
(a) This airworthiness directive (AD) becomes effective October
7, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to BAE Systems (OPERATIONS) LIMITED Model

Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Three events have been reported where insulation material was
found to be fouling pulleys in the aileron interconnect circuit in
the cabin roof area. * * *
Interference between the cable and the insulation bag causes the
material to be drawn into the gap between the pulley and the pulley

restricted aileron movement and consequently, reduced control of the
aeroplane.

Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Actions
(g) Within 6 months after the effective date of this AD, install
new aileron interconnect cable pulley guards, in accordance with
paragraph 2.C. ``Modification'' of the Accomplishment Instructions
of BAE Systems (OPERATIONS) LIMITED Modification Service Bulletin
SB.27-183-36246A, dated December 9, 2008.
