Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2011-0868; Directorate Identifier 2011-CE-027-AD; 
Amendment 39-16854; AD 2011-23-03]
RIN 2120-AA64


Airworthiness Directives; SOCATA Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
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:

    A TBM700 operator reported an occurrence where, as a result of 
handling the standby compass lighting bulb cover in flight, both 
essential bus bars (ESS BUS 1 and ESS BUS 2) failed, leading to loss 
of a number of instruments and navigation systems.
    The technical investigations carried out by SOCATA have shown 
that the cause of this occurrence was that the electrical protection 
of some TBM 700 aeroplanes is insufficient to allow in-flight 
handling of the standby compass lighting cover when energized.
    This condition, if not corrected, may compromise the ability of 
the pilot to safely operate the aeroplane under certain flight 
conditions due to the increase of workload.

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

DATES: This AD is effective December 6, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of December 6, 
2011.

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 August 16, 2011 (75 
FR 50706). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    A TBM700 operator reported an occurrence where, as a result of 
handling the standby compass lighting bulb cover in flight, both 
essential bus bars (ESS BUS 1 and ESS BUS 2) failed, leading to loss 
of a number of instruments and navigation systems.
    The technical investigations carried out by SOCATA have shown 
that the cause of this occurrence was that the electrical protection 
of some TBM 700 aeroplanes is insufficient to allow in-flight 
handling of the standby compass lighting cover when energized.
    This condition, if not corrected, may compromise the ability of 
the pilot to safely operate the aeroplane under certain flight 
conditions due to the increase of workload.
    To address this unsafe condition, SOCATA have developed a 
modification which consists of installing a protection fuse on the 
wire at the standby compass connector, introduced by SOCATA Service 
Bulletin (SB) 70-192-34.
    For the reasons described above, this AD requires installation 
of a protection of the electrical wire at the standby compass 
connector.

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 considered the comment received.

Request To Correct Fax Number

    Jeanne Da Costa of DAHER SOCATA stated that there is a 
typographical error in the fax number for the SOCATA office located in 
France. Currently, the fax number listed under the ADDRESSES section 
and in the Related Information section is +33 (0)5 62 41 7-54. The 
commenter states that the correct fax number is +33 (0)5 62 41 7654 and 
requests the correction be made in the final rule AD action.
    We agree with the commenter and have revised the final rule AD 
action to incorporate the correct fax number.

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

    We estimate that this AD will affect 124 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 $85 per work-hour. Required parts will cost about $350 per product.
    Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $53,940 or $435 per product.
    According to the manufacturer, all 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

[[Page 67342]]

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 (75 FR 50706, August 16, 
2011), 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.

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2011-23-03 SOCATA: Amendment 39-16854; Docket No. FAA-2011-0868; 
Directorate Identifier 2011-CE-027-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective December 6, 
2011.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to SOCATA Model TBM 700 airplanes, serial 
numbers 148, 434 through 572, 574, and 576, certificated in any 
category.

(d) Subject

    Air Transport Association of America (ATA) Code 34: Navigation.

(e) Reason

    The mandatory continuing airworthiness information (MCAI) 
states:

    A TBM700 operator reported an occurrence where, as a result of 
handling the standby compass lighting bulb cover in flight, both 
essential bus bars (ESS BUS 1 and ESS BUS 2) failed, leading to loss 
of a number of instruments and navigation systems.
    The technical investigations carried out by SOCATA have shown 
that the cause of this occurrence was that the electrical protection 
of some TBM 700 aeroplanes is insufficient to allow in-flight 
handling of the standby compass lighting cover when energized.
    This condition, if not corrected, may compromise the ability of 
the pilot to safely operate the aeroplane under certain flight 
conditions due to the increase of workload.
    To address this unsafe condition, SOCATA have developed a 
modification which consists of installing a protection fuse on the 
wire at the standby compass connector, introduced by SOCATA Service 
Bulletin (SB) 70-192-34.
    For the reasons described above, this AD requires installation 
of a protection of the electrical wire at the standby compass 
connector.

(f) Actions and Compliance

    Unless already done, within 6 months after December 6, 2011 (the 
effective date of this AD), install a protection fuse on the wire at 
the standby compass connector following the Accomplishment 
Instructions in DAHER-SOCATA TBM Aircraft Mandatory Service Bulletin 
SB 70-192-34, dated April 2011.

(g) FAA AD Differences

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