RIN 2120-AA64


Airworthiness Directives; Dassault Aviation

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Dassault Aviation Model FALCON 7X airplanes. This proposed AD 
was prompted by investigation results that determined that a certain 
thickness of the fuel tank panels is insufficient to meet the 
certification requirements. This proposed AD would require inspecting 
the thickness of the fuel tank panels, and repair if necessary. We are 
proposing this AD to detect and correct improper thickness of the fuel 
tank panels. Improper thickness increases the risk of damaging and 
puncturing a fuel tank wall panel as a result of a high energy 
lightning strike, which could lead to loss of electrical power and/or 
other essential functions, possibly resulting in reduced control of the 
airplane or ignition of a fuel tank.

DATES: We must receive comments on this proposed AD by May 31, 2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2015-0216, dated October 28, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Dassault 
Aviation Model FALCON 7X airplanes. The MCAI states:

    Several rear fuselage tanks of the Falcon 7X were assembled on 
the production line with a lateral panel, which had been excessively 
chemically-milled in some areas. Investigation results determined 
that the remaining thickness is insufficient to meet the 
certification requirements. Dassault Aviation identified the 
individual aeroplanes that are potentially affected by this 
production deficiency. Due to this reduced thickness, the risk of 
damaging and puncturing a fuel tank wall panel as a result of a high 
energy lightning strike is increased.
    This condition, if not detected and corrected, could lead to 
loss of electrical power and/or other essential functions, possibly 
resulting in reduced control of the aeroplane or ignition of a fuel 
tank.
    To address this potential unsafe condition, Dassault Aviation 
published Service Bulletin (SB) 7X-245 to provide inspection and 
repair instructions.
    For the reasons described above, this [EASA] AD requires a one-
time inspection of

[[Page 21771]]

the fuel tank wall panels and, depending on findings, accomplishment 
of a repair.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
5466.

Related Service Information Under 1 CFR Part 51

    Dassault Aviation has issued Service Bulletin 7X-245, dated June 8, 
2015. The service information describes procedures for measuring fuel 
tank panel thickness, and repair if necessary. This service information 
is reasonably available because the interested parties have access to 
it through their normal course of business or by the means identified 
in the ADDRESSES section.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 6 airplanes of U.S. 
registry.
    We also estimate that it would take about 8 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost about $0 per 
product. Based on these figures, we estimate the cost of this proposed 
AD on U.S. operators to be $4,080, or $680 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 20 work-hours and require parts costing $2,244, for a cost 
of $3,944 per product. We have no way of determining the number of 
aircraft that might need this action.
    According to the manufacturer, some of the costs of this proposed 
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 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    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.

unless already done.

(g) Inspection and Repair

    Within 99 months or 4,100 flight cycles, whichever occurs first 
since the date of first delivery of the airplane, inspect for 
improper thickness of the fuel tank panels, in accordance with the 
Accomplishment Instructions of Dassault Service Bulletin 7X-245, 
dated June 8, 2015. If improper thickness is found during this 
inspection, before further flight, repair the fuel tank panels, in 
accordance with the Accomplishment Instructions of Dassault Service 
Bulletin 7X-245, dated June 8, 2015.
