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 all Airbus Defense and Space
S.A. (formerly known as Construcciones
Aeronauticas, S.A.) Model CN–235, CN–
235–200, and CN–235–300 airplanes.
The NPRM published in the Federal
Register on August 20, 2024 (89 FR
67332). The NPRM was prompted by
AD 2024–0054, dated February 26, 2024
(EASA AD 2024–0054) (also referred to
as the MCAI) issued by the European
Union Aviation Safety Agency (EASA),
which is the Technical Agent for the
Member States of the European Union.
E:\FR\FM\08JAR1.SGM
08JAR1
1360
Federal Register / Vol. 90, No. 5 / Wednesday, January 8, 2025 / Rules and Regulations
The MCAI states a torn bulkhead seal
was found jamming the NLG emergency
cable pulley. Due to the similarity of
design, the MLG emergency cable pulley
could be exposed to the same failure
mode.
In the NPRM, the FAA proposed to
require repetitive inspections and
corrective actions for damage of affected
bulkhead seals and retainer rings, and
repetitive replacement of affected parts,
as specified in EASA AD 2024–0054.
The FAA is issuing this AD to address
a jammed emergency cable pulley,
which could prevent the emergency
extension of the landing gears when
required, causing damage to the airplane
and possible injury to occupants.
You may examine the MCAI in the
AD docket at regulations.gov under
Docket No. FAA–2024–2024.
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.
Material Incorporated by Reference
Under 1 CFR Part 51
EASA AD 2024–0054 specifies
procedures for repetitive general visual
inspections for any type of damage of
the bulkhead seals and the retainer
rings, and, depending on findings,
replacement. EASA AD 2024–0054 also
requires repetitive replacement of
affected parts. 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 10 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
Up to 7 work-hours × $85 per hour = $595 per
inspection/replacement cycle.
$365 per replacement cycle ...
Up to $960 per inspection/replacement cycle.
The FAA estimates the following
costs to do any necessary on-condition
action that would be required based on
the results of any required actions. The
FAA has no way of determining the
Up to $9,600 per inspection/
replacement cycle.

Authority for This Rulemaking
Regulatory Findings
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.
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.

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 all Airbus Defense and
Space S.A. (formerly known as Construcciones Aeronauticas, S.A.) Model
CN-235, CN-235-200, and CN-235-300 airplanes. The NPRM published in the
Federal Register on August 20, 2024 (89 FR 67332). The NPRM was
prompted by AD 2024-0054, dated February 26, 2024 (EASA AD 2024-0054)
(also referred to as the MCAI) issued by the European Union Aviation
Safety Agency (EASA), which is the Technical Agent for the Member
States of the European Union.
[[Page 1360]]
The MCAI states a torn bulkhead seal was found jamming the NLG
emergency cable pulley. Due to the similarity of design, the MLG
emergency cable pulley could be exposed to the same failure mode.
In the NPRM, the FAA proposed to require repetitive inspections and
corrective actions for damage of affected bulkhead seals and retainer
rings, and repetitive replacement of affected parts, as specified in
EASA AD 2024-0054. The FAA is issuing this AD to address a jammed
emergency cable pulley, which could prevent the emergency extension of
the landing gears when required, causing damage to the airplane and
possible injury to occupants.
You may examine the MCAI in the AD docket at regulations.gov under
Docket No. FAA-2024-2024.
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

EASA AD 2024-0054 specifies procedures for repetitive general
visual inspections for any type of damage of the bulkhead seals and the
retainer rings, and, depending on findings, replacement. EASA AD 2024-
0054 also requires repetitive replacement of affected parts. 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 10 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
----------------------------------------------------------------------------------------------------------------
Up to 7 work-hours x $85 per hour = $365 per replacement Up to $960 per Up to $9,600 per
$595 per inspection/replacement cycle. inspection/replacement inspection/replacement
cycle. cycle. cycle.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition action 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 this on-condition action:

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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
2024-25-05 Airbus Defense and Space S.A. (Formerly Known as
Construcciones Aeronauticas, S.A.): Amendment 39-
[[Page 1361]]
22907; Docket No. FAA-2024-2024; Project Identifier MCAI-2024-00140-
T.
(a) Effective Date
This airworthiness directive (AD) is effective February 12,
2025.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all Airbus Defense and Space S.A. (formerly
known as Construcciones Aeronauticas, S.A.) Model CN-235, CN-235-
200, and CN-235-300 airplanes, certificated in any category.
(d) Subject
Air Transport Association (ATA) of America Code 32, Landing
Gear.
(e) Unsafe Condition
This AD was prompted by a torn bulkhead seal found jamming the
nose landing gear emergency cable pulley. Due to the similarity of
design, the main landing gear emergency cable pulley could be
exposed to the same failure mode. The FAA is issuing this AD to
address this potential unsafe condition, which could prevent the
emergency extension of the landing gears when required, causing
damage to the airplane and possible injury to occupants.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Requirements
Except as specified in paragraphs (h) and (i) of this AD: Comply
with all required actions and compliance times specified in, and in
accordance with, European Union Aviation Safety Agency (EASA) AD
2024-0054, dated February 26, 2024 (EASA AD 2024-0054).
(h) Exceptions to EASA AD 2024-0054
(1) Where EASA AD 2024-0054 refers to its effective date, this
AD requires using the effective date of this AD.
(2) Where paragraph 3.1.1 of the Alert Operators Transmission
(AOT) specified in EASA AD 2024-0054, states ``each year (1 Year
between 8 and 10 Years since component installation) since the
inspection,'' this AD requires replacing that text with ``within one
year after the last inspection''.
(3) This AD does not adopt the ``Remarks'' section of EASA AD
2024-0054.
(i) No Reporting Requirement
Although the material referenced in EASA AD 2024-0054 specifies
to submit certain information to the manufacturer, this AD does not
include that requirement.
(j) Additional AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Validation Branch, FAA, has the authority to approve
AMOCs for this AD, if requested using the procedures found in 14 CFR
