14 CFR Part 39
[Docket No. FAA-2024-0998; Project Identifier MCAI-2023-01212-T;
Amendment 39-22778; AD 2024-13-04]
RIN 2120-AA64
Airworthiness Directives; Dassault Aviation Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD)
for
certain Dassault Aviation Model FALCON 7X airplanes. This AD was
prompted by a determination that non-conforming washers may have been
installed in production on engine 1 and 3 forward yokes. This AD
requires a one-time inspection for non-conforming washers and,
depending on findings, related investigative and corrective actions, as
specified in a European Union Aviation Safety Agency (EASA) AD, which
is incorporated by reference. The FAA is issuing this AD to address the
unsafe condition on these products.
DATES: This AD is effective August 16, 2024.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of August 16,
2024.
ADDRESSES:
AD Docket: You may examine the AD docket at regulations.gov under
Docket No. FAA-2024-0998; or in person at Docket Operations between 9
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD
docket
contains this final rule, the mandatory continuing airworthiness
information (MCAI), any comments received, and other information. The

SUPPLEMENTARY INFORMATION:
Background
The FAA 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 April 9, 2024 (89 FR 24748). The NPRM was prompted by AD
2023-0208, dated November 22, 2023 (EASA AD 2023-0208) (also referred
to as the MCAI), issued by EASA, which is the Technical Agent for the
Member States of the European Union. The MCAI states that a quality
review revealed that nonconforming washers may have been installed in
production on engine 1 and 3 forward yokes. This condition, if not
addressed, could lead to cracks in the bolts and the engine forward
yokes, possibly resulting in loss of a lateral engine.
In the NPRM, the FAA proposed to require a one-time inspection for
non-conforming washers and, depending on findings, related
investigative and corrective actions, as specified in EASA AD 2023-
0208. The FAA is issuing this AD to address the unsafe condition on
these products.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2024-0998.
Discussion of Final Airworthiness Directive
Comments
The FAA received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
This product has been approved by the aviation authority of another
country and is approved for operation in the United States. Pursuant to
the FAA's bilateral agreement with this State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI
referenced above. The FAA reviewed the relevant data and determined
that air safety requires adopting this AD as proposed. Accordingly, the
FAA is issuing this AD to address the unsafe condition on this product.
Except for minor editorial changes, this AD is adopted as proposed in
the NPRM. None of the changes will increase the economic burden on any
operator.
Related Material Under 1 CFR Part 51
EASA AD 2023-0208 specifies procedures for a one-time inspection
for non-conforming (non-compliant) double countersink washers on the
engine 1 and 3 forward yokes, installing the engine 1 and 3 forward
yokes with new attachments, and, depending on findings, related
investigative and corrective actions. Related investigative and
corrective actions include a special detailed fatigue inspection for
cracking of the engine forward yokes and replacement if any cracking is
found. This material 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
The FAA estimates that this AD affects 8 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
|
Labor cost
|
Parts cost
|
Cost per
product
|
Cost on
U.S. operators
|
| 8 work-hours x $85 per hour =
$680 |
$16,280
|
$16,960
|
$135,680
|
The FAA estimates the following costs
to do any necessary on-
condition actions that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need these on-condition actions:
Estimated Costs of On-Condition Actions
|
Labor cost
|
Parts cost
|
Cost per
product
|
| 8 work-hours x $85 per hour =
$680 |
$33,170
|
$33,850
|
The FAA has included all known costs
in its cost estimate.
According to the manufacturer, however, some or all of the costs of
this AD may be covered under warranty, thereby reducing the cost impact
on affected operators.
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.
The FAA is 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
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) Will not affect intrastate aviation in Alaska, and
(3) 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.
