Airworthiness Directives; 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:

    It was noticed on assembly line an elongation of bolts 
connecting power leads on R700 and R701 shunts. An incorrect 
tightening torque value is likely to be the cause of the elongation.
    This condition, if left uncorrected could lead to heating, 
electrical arcing or smokes and could result in an in-flight loss of 
electrical power.

We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective January 4, 2010.
    On January 4, 2010, 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 September 28, 2009 
(74 FR 49345). That NPRM proposed to correct an unsafe condition for 
the specified products. The MCAI states:

    It was noticed on assembly line an elongation of bolts 
connecting power leads on R700 and R701 shunts. An incorrect 
tightening torque value is likely to be the cause of the elongation.
    This condition, if left uncorrected could lead to heating, 
electrical arcing or smokes and could result in an in-flight loss of 
electrical power.
    For the reason described above, this Airworthiness Directive 
(AD) mandates the replacement of the power lead bolts on R700 and 
R701 shunts.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comment received.

Comment Issue: Costs of Compliance

    Ms. Catherine H[eacute]rau, SOCATA, states the cost of the required 
parts (4 bolts) is $10, not $50. Consequently, the cost of the proposed 
AD on U.S. operators is $2,350 or $50 per product.
    We agree with the commenter, and we are changing the costs of 
compliance in the final rule AD action to reflect the more accurate 
estimated costs.

Conclusion

    We reviewed the available data, including the comment received, 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 MCAI in order to follow FAA policies. Any such differences are 
highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect 47 products of U.S. registry. 
We also estimate that it will take about 0.5 work-hour per product to 
comply with the basic requirements of this AD. The average labor rate 
is $80 per work-hour. Required parts will cost about $10 per product. 
Where the service information lists required parts costs that are 
covered under warranty, we have assumed that there will be no charge or 
a lower 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. 
operators to be $2,350 or $50 per product.

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.

Subject

    (d) Air Transport Association of America (ATA) Code 24: Electric 
Power.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    It was noticed on assembly line an elongation of bolts 
connecting power leads on R700 and R701 shunts. An incorrect 
tightening torque value is likely to be the cause of the elongation.

electrical arcing or smokes and could result in an in-flight loss of 
electrical power.
    For the reason described above, this Airworthiness Directive 
(AD) mandates the replacement of the power lead bolts on R700 and 
R701 shunts.

Actions and Compliance

    (f) Unless already done, within the next 100 hours time-in-
service after January 4, 2010 (the effective date of this AD), or 
within the next 12 months after January 4, 2010 (the effective date 
of this AD), whichever occurs first, replace the bolts of shunts 
R700 and R701 following DAHER-SOCATA Mandatory Service Bulletin SB 
70-169, dated May 2009.

FAA AD Differences

    Note: This AD differs from the MCAI and/or service information 
as follows: No differences.
