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 review showing that inadequate
clearance may exist between certain electrical wiring and nearby structures. This AD requires an
inspection of certain electrical wiring bundles and feeders, modifications, and corrective actions if
necessary. We are issuing this AD to address the unsafe condition on these products.

Dates:
This AD is effective November 6, 2017.
The Director of the Federal Register approved the incorporation by reference of a certain
publication listed in this AD as of November 6, 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 June 12, 2017 (82 FR 26867) (“the NPRM”). The NPRM was prompted by
a review showing that inadequate clearance may exist between certain electrical wiring and nearby
structures. The NPRM proposed to require an inspection of certain electrical wiring bundles and
feeders, modifications, and corrective actions if necessary. We are issuing this AD to detect and
correct inadequate clearances between electrical wiring and nearby structures, which could lead to
interference or contact with a structure and cause an electrical short circuit or fluid leakage. This
could result in the loss of several functions essential for safe flight.
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member
States of the European Union, has issued EASA Airworthiness Directive 2016-0230, dated
November 21, 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 review of the wiring and tubing lay-out showed that there may be low clearance
between electrical wiring and nearby structure. Although no in-service incident has
been reported, the minimum clearances could deteriorate over time.

This condition, if not detected and corrected, could lead to interference or contact with
structure, provoking an electrical short circuit or fluid leakage, possibly resulting in
loss of several functions essential for safe flight.

To initially address this potential unsafe condition, [Dassault Aviation] DA developed
some interim modifications (mod) addressing the risk of short circuit and fluid
leakage, and EASA issued AD 2010-0029 (later revised) [which corresponds to FAA
AD 2011-14-04, Amendment 39-16739 (76 FR 39256, July 6, 2011) (“AD 2011-14-
04”)] to require embodiment of those modifications in-service.

Since EASA AD 2010-0029R1 was issued, DA developed another set of
modifications, available for in-service application through Service Bulletin (SB) F7X-
056, which are considered the final solutions for this unsafe condition.

For the reasons described above, this [EASA] AD requires a one-time [general visual]
inspection [for worn or damaged wiring or connectors due to inadequate clearance
between wiring and nearby structures] of the affected electrical wiring and, depending
on findings, corrective action(s) and modification of the aeroplane.

Corrective actions include modifying the clamping and routing; adding new brackets, clamps,
and cable protections; replacing damaged parts; and improving connections using lock wires. You

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-056, Revision 1, dated July 20, 2016. This
service information describes procedures for an inspection of certain electrical wiring (wiring bundles
and feeders), corrective actions, and modification of the airplane. 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 51 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

Estimated Costs
Action Labor cost Parts Cost per Cost on U.S.
cost product operators
Inspection and 31 work-hours × $85 per $7,660 $10,295 $525,045
modifications hour = $2,635

We have received no definitive data that will enable us to provide cost estimates for the on-
condition actions specified in this AD.

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.

3
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.
