14 CFR Part 39

[Docket No. FAA-2010-0477; Directorate Identifier 2009-NM-226-AD; 
Amendment 39-16423; AD 2010-18-10]

Airworthiness Directives; BAE Systems (Operations) Limited Model 
BAe 146 and Avro 146-RJ Airplanes

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.

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, 
Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC.

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.
