Airworthiness Directives; Dassault Aviation Airplanes

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

ACTION: Final rule.

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

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

[[Page 6121]]

Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a 
report indicating that fuselage panels were manufactured with defects 
that could reduce panel fatigue limits. This AD requires a one-time 
inspection of the affected panels and repair if necessary, and for 
certain airplanes, installation of a stiffener. We are issuing this AD 
to address the unsafe condition on these products.

DATES: This AD is effective March 20, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 20, 
2018.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Dassault Aviation 
Model FALCON 7X airplanes. The NPRM published in the Federal Register 
on July 14, 2017 (82 FR 32498) (``the NPRM''). The NPRM was prompted by 
a report indicating that fuselage panels were manufactured with defects 
that could reduce panel fatigue limits. The NPRM proposed to require a 
one-time inspection of the affected panels and corrective actions if 
necessary. We are issuing this AD to detect and correct discrepancies 
of certain fuselage lateral panels, which could lead to crack 
propagation and possible reduced structural integrity of the fuselage.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2016-0250, dated December 15, 2016 (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:

    A few pockets of fuselage Section T5 lateral panels were 
manufactured with defects in certain chemically-milled profiles. The 
technical investigation concluded that the fatigue limit of the 
affected panels might be reduced, depending on the defect 
characteristics.
    This condition, if not detected and corrected, could lead to 
crack propagation, possibly resulting in reduced structural 
integrity of the fuselage.
    To address this potential unsafe condition, DA published Service 
Bulletin (SB) F7X-042 providing inspection instructions.
    For the reasons described above, this [EASA] AD requires a one-
time [detailed] inspection of the chemically-milled profiles of the 
pockets of the Section T5 fuselage lateral panels and, depending on 
findings, accomplishment of applicable corrective action(s). This 
[EASA] AD also requires, for some aeroplanes, the installation of a 
stiffener on the forward pocket.

    Applicable corrective actions include repair, if necessary. 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-2017-
0694.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed, except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Dassault Service Bulletin 7X-042, Revision 1, dated May 
3, 2016. This service information describes the inspection of the 
chemically milled profiles of the pockets of the Section T5 fuselage 
lateral panels and the installation of a stiffener on the forward 
pocket on affected airplanes. 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.

Costs of Compliance

    We estimate that this AD affects 4 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
             Action                  Labor cost        Parts cost     Cost per product    Cost on U.S. operators

Panel inspections..............  Up to 10 work-                  $0  Up to $850........  Up to $3,400.
                                  hours x $85 per

 airplanes).                      per hour = $170.
----------------------------------------------------------------------------------------------------------------


[[Page 6122]]

    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 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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.
