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
Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a
discovery of noncompliant rivets in the flight deck upper skin. This AD
requires replacement of noncompliant rivets. We are issuing this AD to
address the unsafe condition on these products.
DATES: This AD is effective October 5, 2017.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of October 5,
2017.

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 May 31, 2017 (82 FR 24910) (``the NPRM''). The NPRM was prompted by
a discovery of noncompliant rivets in the flight deck upper skin. The
NPRM proposed to require replacement of noncompliant rivets. We are
issuing this AD to prevent interference between the rivet shank and the
flight deck mounted overhead panel when the flight deck upper skin
deforms due to impact (e.g., bird strike). This condition, if not
corrected, could affect the functioning of essential flight control
systems, and result in reduced control of the airplane.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2016-0124, dated June 22, 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:
During an internal review of the manufacturing files, it was
found that 20 rivets installed on the cockpit [(flight deck)] upper
skin are not compliant with the original type design. Those 20 MGPL
type rivets have a shank longer than necessary and, in case of a
bird strike under maximum energy impact, the cockpit upper skin
deformation would lead to interference between the rivet shank and
the cockpit mounted overhead panel.
This condition, if not corrected, could affect the functioning
of essential flight control systems, possibly resulting in reduced
control of the aeroplane.
To address this potential unsafe condition, Dassault Aviation
published Service Bulletin (SB) F7X-176, providing instructions for
replacement of the [noncompliant] rivets.
For the reasons described above, this [EASA] AD requires removal
of affected rivets and replacement with serviceable [solid-type]
rivets compliant with original type design.
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-
0502.
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.
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
Dassault Aviation has issued Service Bulletin 7X-176, dated
February 3, 2016. This service information describes procedures for
modifying the airplane by replacing certain blind rivets installed on
the flight deck skin panel with solid-type rivets. 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 25 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 |
Modification |
81 work-hours x $85 per hour
= $6,885 |
$48 |
$6,933 |
$173,325 |
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.
