SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a
report that a passenger oxygen pipe at frame 10 was chafing against the
forward lavatory rear structure, raising the risk of the oxygen pipe
developing a crack. This AD requires modifying the routing of and, if
necessary, replacing, the oxygen pipe. We are issuing this AD to
prevent rupture of the oxygen pipe which, in case of a cabin
depressurization, would impair operation of the passenger oxygen
distribution system.
DATES: This AD becomes effective September 11, 2012.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of September
11, 2012.
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,

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 20, 2012 (77
FR 16186). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
Inspections of two aeroplanes during cabin completions have
shown that a passenger oxygen line at frame 10 was chafing with the
forward lavatory rear structure.
Design review of the area confirmed a local low clearance value
which raises the risk of the oxygen line developing a crack.
This condition, if not detected and corrected, could lead to
rupture of the oxygen line which, in case of a cabin
depressurization, would impair operation of the passengers' oxygen
distribution system.
To address this unsafe condition, Dassault Aviation have
designed a modification with a new oxygen line routing.
This AD requires an [general visual] inspection of the oxygen
line for interference or damage and, in case of discrepancies
[damage, or clearance less than 3 mm], accomplishment of the
modification [including general visual inspections, and, if
necessary, replacing the oxygen line/pipe] before next flight. It
requires as well accomplishment of the modification of the oxygen
line routing for the aeroplanes in which [clearance of 3 mm or more
but less than 12 mm] were identified.
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 (77 FR 16186, March 20,
2012) or on the determination of the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed--except for
minor editorial changes. We have determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM (77 FR 16186, March 20, 2012) for correcting the unsafe condition;
and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (77 FR 16186, March 20, 2012).
Costs of Compliance
We estimate that this AD will affect about 11 products of U.S.
registry. We also estimate that it will take about 11 work-hours per
product to comply with the basic requirements of this AD. The average
labor rate is $85 per work-hour. Based on these figures, we estimate
the cost of this AD to the U.S. operators to be $10,285, or $935 per
product.
[[Page 46947]]
In addition, we estimate that any necessary follow-on actions would
take about 16 work-hours and require parts costing $655, for a cost of
$2,015 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 that 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);
3. Will not affect intrastate aviation in Alaska; and
4. 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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM 77 FR 16186, March 20, 2012),
the regulatory evaluation, any comments received, and other
information. The street address for the Docket Operations office
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will
be available in the AD docket shortly after receipt.
