Airworthiness Directives; Dassault Aviation Model FALCON 2000
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 2000 airplanes. This AD was prompted by
a report of chafing of a wire bundle located at the bottom of the right
hand (RH) electrical cabinet. This AD requires a one-time general
visual inspection of the wiring bundle for damage, measurement of the
clearance between the metallic plate and the wiring bundle, and
corrective actions if necessary. We are issuing this AD to address the
unsafe condition on these products.

DATES: This AD is effective January 18, 2019.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of January 18,
2019.

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 2000 airplanes. The NPRM published in the Federal Register
on October 9, 2018 (83 FR 50537). The NPRM was prompted by a report of
chafing of a wire bundle located at the bottom of the RH electrical
cabinet. The NPRM proposed to require a one-time general visual
inspection of the wiring bundle for damage, measurement of the
clearance between the metallic plate and the wiring bundle, and
corrective actions if necessary.
We are issuing this AD to address chafing of a wire bundle located
at the bottom of the RH electrical cabinet, which may cause damage to
wires within the bundle, and, if not detected and corrected, could lead
to improper functioning of airplane systems (such as loss of wing anti-
icing or wing anti-icing inoperative indication, loss of normal braking
indication, and loss of ``No take-off'' indication), which could 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 AD
2018-0114, dated May 23, 2018, (referred to after this as the Mandatory
Continuing Airworthiness Information, or ``the MCAI''), to correct an
unsafe condition for certain Dassault Aviation Model FALCON 2000
airplanes. The MCAI states:

One Falcon 2000 aeroplane experienced some chafing of a wire
bundle located at the bottom of the right-hand (RH) electrical
cabinet (between Frames 4 and 5). The wire loom interfered with a
metallic (ground) plate of terminal strip 700J and at least 12 wires
were damaged. This wire loom includes 250 wires and in case of
chafing, any wire may be damaged.
This condition, if not detected and corrected, could lead to
improper functioning of aeroplane systems [such as loss of wing
anti-icing or wing anti-icing inoperative indication, loss of normal
braking indication, and loss of ``No take-off'' indication],
possibly resulting in reduced control of the aeroplane.
To address this potential unsafe condition, Dassault developed a
modification M3889 to improve the clearance between the metallic
plate and the wire loom, and published the SB [Dassault Aviation
Service Bulletin F2000-436] to inspect and modify aeroplanes in
service.
For the reasons described above, this [EASA] AD requires a one-
time inspection of the wiring bundle for interference or damage,
measurement of the clearance between the metallic plate and the
wiring bundle, and depending on findings, modification of the
aeroplane by cutting out the lower part of the ground plate of
terminal strip 700J and adding an edge protection to prevent
interference. Aeroplanes that do not have a metallic plate installed
are not affected by this [EASA] AD.

www.regulations.gov by searching for and locating Docket No. FAA-2018-
0809.

Comments

We gave the public the opportunity to participate in developing
this final rule. We have considered the comments received. Lucas Kline
indicated his support for the NPRM.

Conclusion

We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this final rule 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 addressing 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 F2000-436, dated
September 28, 2017. This service information describes procedures for a
one-time general visual inspection of the wiring bundle for damage
(including chafing), measurement of the clearance between the metallic
plate and the wiring bundle, and corrective actions. Corrective actions
include modification of the airplane by cutting out the lower part of
the ground plate of terminal strip 700J and adding an edge protection
to prevent interference and replacement of damaged wires. 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 195 airplanes of U.S. registry. We
estimate the following costs to comply with this AD:

Estimated Costs

We estimate the following costs to do the necessary on-condition
action that would be required based on the results of any required
actions. We have no way of determining the number of aircraft that
might need this on-condition action:

Estimated Costs of On-Condition Actions

* We have received no definitive data for the parts cost for the on-
condition 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.
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 and
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

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.
