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.

ADDRESSES: You may examine the AD docket on the Internet at http://
www.regulations.gov or in person at Document Management Facility, 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 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.

    (1) Within the next 100 hours time-in-service after May 20, 2009 
(the effective date of this AD) or within the next 12 months after 
May 20, 2009 (the effective date of this AD), whichever occurs 
first, inspect the electrical wiring harness at frame C14 and 
between frames C16 and C17 for wire chafing and incorrect routing 
following EADS SOCATA Mandatory Service Bulletin SB 70-163, dated 
November 2008.
    (2) If any wire chafing and/or incorrect routing are found, 
before further flight, repair and reroute the electrical harness 
following EADS SOCATA Mandatory Service Bulletin SB 70-163, dated
