Airworthiness Directives; Dassault Aviation Model FALCON 7X 
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) originated 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:

    On some Falcon 7X aeroplanes, it has been determined potential 
low clearance between electrical wiring or hydraulic pipe and nearby 
structure.
    Although no in service incident has been reported, there is no 
certainty that the minimum clearances would be maintained over time. 
In the worst case, interference or contact with structure might 
occur and lead to electrical short circuits or fluid leakage, 
potentially resulting in loss of several functions essential for 
safe flight.
* * * * *


[[Page 39257]]


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

DATES: This AD becomes effective August 10, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 10, 
2011.

ADDRESSES: You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> or in person at the 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 March 8, 2011 (76 FR 
12624). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    On some Falcon 7X aeroplanes, it has been determined potential 
low clearance between electrical wiring or hydraulic pipe and nearby 
structure.
    Although no in service incident has been reported, there is no 
certainty that the minimum clearances would be maintained over time. 
In the worst case, interference or contact with structure might 
occur and lead to electrical short circuits or fluid leakage, 
potentially resulting in loss of several functions essential for 
safe flight.
    Dassault Aviation has developed two Service Bulletins (SB) that 
provide corrective actions to ensure the minimum required clearance, 
as well as adequate protection between hydraulic pipe (SB n[deg] 0 
92) and electrical wiring (SB n[deg] 006) and the aeroplane 
structure.
    This [European Aviation Safety Agency (EASA)] AD requires the 
implementation of both SBs on the affected aeroplanes.
    Since issuance of EASA AD 2010-0029, Dassault Aviation has 
developed modifications M1036 and M1037. M1036 is equivalent to 
M1007 while M1037 is equivalent to M1020. These modifications are 
embodied during production on new aeroplanes.
    This [EASA] AD has been revised to exclude from the AD 
applicability the aeroplanes on which those modifications are 
embodied.

    Required actions include general visual inspections for damage of 
wiring bundles and feeders. Damage includes, but is not limited to: 
Signs of overheat, discoloration, or damaged and cut strands on the 
cables and insulating sleeves. Corrective actions for damage of wiring 
bundles and feeders include repairing damage. Other required actions 
include modifying the applicable wiring and layout, a general visual 
inspection for absence of marks of the rear tank wall at the contact 
area, installing a protective plate on the rear tank wall, and 
installing a hydraulic pipe if necessary. If contact marks are found, 
required actions include an eddy current inspection or a penetrant 
inspection for cracks, and repair if necessary. 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 received no comments on the NPRM or on the determination of 
the cost to the public.

Editorial Change

    We have made a minor editorial change to paragraph (g)(3)(ii)(A) of 
this AD.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD with the change described 
previously. We determined that this change 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 our FAA policies. Any such differences 
are highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect 21 products of U.S. registry. 
We also estimate that it will take about 65 work-hours 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 $0 per product. 
Where the service information lists required parts costs that are 
covered under warranty, we have assumed that there will be no 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 $116,025, or $5,525 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 the 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.
