Airworthiness Directives; EADS SOCATA Model TBM 700 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) 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:
A damaged wiring harness which caused the air conditioning
system circuit breaker to trip and evidencing a local overheating
has been found on an in-service aircraft.
The investigation revealed that the damage (chafed wires) found
on the wiring harness resulted from an interference with the under-
floor attachment fittings of the cabin partition
[[Page 17387]]
net which was due to an incorrect routing of the harness while on
the production line.
Such conditions could result in an electrical short and
potential loss of several functions essential for the safety of
flight.
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective May 20, 2009.
On May 20, 2009, the Director of the Federal Register approved the
incorporation by reference of certain publications listed in this AD.

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 February 13, 2009
(74 FR 7194). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
A damaged wiring harness which caused the air conditioning
system circuit breaker to trip and evidencing a local overheating
has been found on an in-service aircraft.
The investigation revealed that the damage (chafed wires) found
on the wiring harness resulted from an interference with the under-
floor attachment fittings of the cabin partition net which was due
to an incorrect routing of the harness while on the production line.
Such conditions could result in an electrical short and
potential loss of several functions essential for the safety of
flight.
For the reason stated above, this AD mandates inspection of the
electrical wiring harness, and if necessary a rework of its routing.
Comments
We gave the public the opportunity to participate in developing
this AD. We have considered the comment received.
Comment Issue: Number of U.S.-Registered Airplanes
EADS SOCATA requests we change in the Costs of Compliance section
the number of products affected on the U.S. registry from 45 products
to 31 products. They state the airplanes listed in the U.S. registry
are serial numbers 434, 435, 437 through 439, 441, 443 through 451,
458, 459, 461, 462, 465, 466, 468 through 474, and 476 through 478.
The FAA agrees. We will change the Costs of Compliance section in
the final rule AD action to reflect the above comment.
Conclusion
We reviewed the available data, including the comment received, and
determined that air safety and the public interest require adopting the
AD with the changes described previously. We determined that these
changes will not increase the economic burden on any operator or
increase the scope of the AD.
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 FAA policies. Any such differences are
highlighted in a NOTE within the AD.
Costs of Compliance
Based on the service information, we estimate that this AD will
affect 31 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 $80 per work-hour.
Based on these figures, we estimate the cost of this AD to the U.S.
operators to be $2,480 or $80 per product.
In addition, we estimate that any necessary follow-on actions would
take about 1.5 work-hours for a cost of $120 per product. We have no
way of determining the number of products that may need these actions.
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 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 Management Facility
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.
