AGENCY: Federal Aviation Administration
(FAA), Department of
Transportation (DOT).
ACTION: Final rule.
SUMMARY: We are adopting a new airworthiness directive (AD) for
Socata
Model TBM 700 airplanes. This AD results from mandatory continuing
airworthiness information (MCAI) issued 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
installation of the wrong (switched) aileron control cables in the
wing. This unsafe condition could lead to restricted movement of the
aileron, resulting in reduced control of the airplane. We are issuing
this AD to require actions to address the unsafe condition on these
products.
DATES: This AD is effective February 15, 2012.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of February 15,
2012.

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 October 21, 2011 (76
FR 65419). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
A TBM 700 operator reported a case of inverted installation of
aileron control cables in the wing. The shortest cable was found
installed instead of the longest one on wing tip side, with left
hand (LH) threaded end in upper section. This wrong installation
could have been caused by mistaken maintenance data.
This condition, if not detected and corrected, could lead to
restricted movement of the aileron, resulting in reduced control of the
aeroplane,
particularly when operating under adverse flight conditions on
landing and during avoidance manoeuvres.
For the reasons described above, this AD requires an inspection
to verify the correct installation of the aileron control cables
and, in case of discrepancies, proper re-installation of the cables
in accordance with the approved design configuration.
Even with potentially reduced aileron deflection, Socata's analysis
shows that the airplane is still capable of achieving its published
cross wind landing limits.
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.
Costs of Compliance
We estimate that this AD will affect 404 products of U.S. registry.
We also estimate that it would take about 0.5 work-hour per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Required parts would cost about $0 per product.
Based on these figures, we estimate the cost of the AD on U.S.
operators to be $17,170, or $43 per product.
In addition, we estimate that any necessary follow-on actions would
take about 16 work-hours and require parts costing $0, for a cost of
$1,360 per product. We have no way of determining the number of
products that may need these actions.
According to the manufacturer, some of the costs of this AD may be
covered under warranty, thereby reducing the cost impact on affected
individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.
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),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
Examining the AD Docket
You may examine the AD docket on the Internet at http://www.regulations.gov;

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 Office (telephone (800) 647-5527) is in the ADDRESSES
section. Comments will be available in the AD docket shortly after
receipt.
