Federal Register / Vol. 89, No. 2 / Wednesday, January 3, 2024 / Rules and Regulations
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.

SUPPLEMENTARY INFORMATION:
VerDate Sep<11>2014
16:21 Jan 02, 2024
Jkt 262001
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2021–02–18,
Amendment 39–21401 (86 FR 10740,
February 23, 2021) (AD 2021–02–18)
(which corresponds to EASA AD 2020–
0159). AD 2021–02–18 applied to all
Airbus Defense and Space S.A. Model
CN–235, CN–235–100, CN–235–200,
and CN–235–300 airplanes and Model
C–295 airplanes. AD 2021–02–18
required repetitive inspections for
cracking or broken rivets of certain leftand right-hand stringers and
surrounding structure, and repair if
necessary. The FAA issued AD 2021–
02–18 to address such cracking in the
stringers, which could result in reduced
structural integrity of the airplane. FAA
AD 2021–02–18 explained that the
requirements were ‘‘interim action,’’
and further rulemaking was being
considered. The FAA has now
determined that further rulemaking is
necessary, and this AD follows from that
determination.
The NPRM published in the Federal
Register on October 18, 2023 (88 FR
71778). The NPRM was prompted by
AD 2023–0103, dated May 23, 2023,
issued by EASA, which is the Technical
Agent for the Member States of the
European Union (EASA AD 2023–0103)
(also referred to as the MCAI). The
MCAI states that since EASA AD 2020–
0159 was issued, a modification was
developed to reinforce the structure in
the affected area, which is a terminating
action for the repetitive inspections
required by EASA AD 2020–0159. The
MCAI does not include Model CN–235–
100 airplanes since a determination was
made that the only remaining airplanes
in service are operated by a government
military service. The FAA has
determined that since these models
remain on the FAA type certificate data
sheet, AD action is necessary to address
the unsafe condition. Therefore, this AD
includes this model in the AD
applicability and provides corrective
actions to address the unsafe condition.
In the NPRM, the FAA proposed to
continue certain actions in EASA AD
2020–0159. The NPRM also proposed to
require the new terminating action for
the repetitive inspections, as specified
in EASA AD 2023–0103. 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–2023–1999.

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 Service Information Under 1
CFR Part 51
EASA AD 2023–0103 specifies
procedures for detailed visual (DET) or
high frequency eddy current inspections
of the stringer P0a and P0a’ at the
riveted line of the attachment to the
gusset and along the stringer head, in
particular at the area of the last
attachment of the gusset to the stringer
in the midpoint between FR43 and
FR44, DET inspections for fatigue cracks
of the fuselage skin, along the stringers’
footprint and surrounding structure and
the attachment of the gusset to the FR43;
DET inspections for fatigue cracks of the
actuator bracket on FR43, along the
radius of the vertical nerves, inner lug
holes, and attachment holes of the
bracket to FR43; DET inspections for
fatigue cracks or broken rivets in the
web and joint clips to skin and stringer
of both sides of the frame between
stringer P1d and P1d’ (two stringers for
each side from the central stringer P0a);
DET inspections for fatigue cracks or
broken rivets of the gussets, along the
flange which joins FR43; and repair of
any cracking or broken rivets.
EASA AD 2023–0103 also specifies
procedures for modifying structures
between frames FR43 and FR44, on
stringers STGR0A and STGR0A’:
Replacing supports, formers, installing
fittings, radius guards, and hardware
attachments.

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.

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2021-02-
18, which applied to all Airbus Defense and Space S.A. Model CN-235,
CN-235-100, CN-235-200, and CN-235-300 airplanes and Model C-295
airplanes. AD 2021-02-18 required
[[Page 249]]
repetitive inspections for cracking or broken rivets of certain left-
and right-hand stringers and surrounding structure, and repair if
necessary. This AD was prompted by a modification that was developed to
reinforce the structure in the affected area, providing terminating
action for the repetitive inspections required by AD 2021-02-18. This
AD continues to require certain actions in AD 2021-02-18 and requires
the new terminating action for the repetitive inspections, 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.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2021-02-18, Amendment 39-21401 (86 FR
10740, February 23, 2021) (AD 2021-02-18) (which corresponds to EASA AD
2020-0159). AD 2021-02-18 applied to all Airbus Defense and Space S.A.
Model CN-235, CN-235-100, CN-235-200, and CN-235-300 airplanes and
Model C-295 airplanes. AD 2021-02-18 required repetitive inspections
for cracking or broken rivets of certain left- and right-hand stringers
and surrounding structure, and repair if necessary. The FAA issued AD
2021-02-18 to address such cracking in the stringers, which could
result in reduced structural integrity of the airplane. FAA AD 2021-02-
18 explained that the requirements were ``interim action,'' and further
rulemaking was being considered. The FAA has now determined that
further rulemaking is necessary, and this AD follows from that
determination.
The NPRM published in the Federal Register on October 18, 2023 (88
FR 71778). The NPRM was prompted by AD 2023-0103, dated May 23, 2023,
issued by EASA, which is the Technical Agent for the Member States of
the European Union (EASA AD 2023-0103) (also referred to as the MCAI).
The MCAI states that since EASA AD 2020-0159 was issued, a modification
was developed to reinforce the structure in the affected area, which is
a terminating action for the repetitive inspections required by EASA AD
2020-0159. The MCAI does not include Model CN-235-100 airplanes since a
determination was made that the only remaining airplanes in service are
operated by a government military service. The FAA has determined that
since these models remain on the FAA type certificate data sheet, AD
action is necessary to address the unsafe condition. Therefore, this AD
includes this model in the AD applicability and provides corrective
actions to address the unsafe condition.
In the NPRM, the FAA proposed to continue certain actions in EASA
AD 2020-0159. The NPRM also proposed to require the new terminating
action for the repetitive inspections, as specified in EASA AD 2023-
0103. 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-2023-1999.
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 Service Information Under 1 CFR Part 51
EASA AD 2023-0103 specifies procedures for detailed visual (DET) or
high frequency eddy current inspections of the stringer P0a and P0a' at
the riveted line of the attachment to the gusset and along the stringer
head, in particular at the area of the last attachment of the gusset to
the stringer in the midpoint between FR43 and FR44, DET inspections for
fatigue cracks of the fuselage skin, along the stringers' footprint and
surrounding structure and the attachment of the gusset to the FR43; DET
inspections for fatigue cracks of the actuator bracket on FR43, along
the radius of the vertical nerves, inner lug holes, and attachment
holes of the bracket to FR43; DET inspections for fatigue cracks or
broken rivets in the web and joint clips to skin and stringer of both
sides of the frame between stringer P1d and P1d' (two stringers for
each side from the central stringer P0a); DET inspections for fatigue
cracks or broken rivets of the gussets, along the flange which joins
FR43; and repair of any cracking or broken rivets.
EASA AD 2023-0103 also specifies procedures for modifying
structures between frames FR43 and FR44, on stringers STGR0A and
STGR0A': Replacing supports, formers, installing fittings, radius
guards, and hardware attachments.

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 17 work-hours x $85 per hour = Up to $14,002.......... Up to $15,447.......... Up to $154,470.
Up to $1,445.
----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data on which to base the 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.
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.
