SUPPLEMENTARY INFORMATION:
lotter on DSK11XQN23PROD with RULES1
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 Airbus Canada Limited
Partnership Model BD–500–1A10 and
BD–500–1A11 airplanes. The NPRM
published in the Federal Register on
October 27, 2023 (88 FR 73772). The
NPRM was prompted by AD CF–2023–
20, dated March 22, 2023, issued by
Transport Canada, which is the aviation
authority for Canada (Transport Canada
AD CF–2023–20) (also referred to as the
MCAI). The MCAI states that multiple
occurrences of low clearance or fouling
between certain wiring harnesses and a
hydraulic bracket and structure in the
wing trailing edge area were detected on
the production line. These conditions
were caused by an inappropriate
distribution of slack in the wiring
harnesses. Low clearance or fouling
between the wiring harnesses and
adjacent structure could result in wear
of the harnesses leading to electrical
arcing. Arcing in the presence of a leak
from the hydraulic lines in the area
could lead to a fire.
In the NPRM, the FAA proposed to
require inspecting certain wiring
harnesses for any damage and clearance
to adjacent structure and corrective
actions, as specified in Transport
Canada AD CF–2023–20. The NPRM
also proposed to require an inspection
report. 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–2023–2135.

Discussion of Final Airworthiness
Directive
Comments
The FAA received comments from
Delta Air Lines (Delta). The following
presents the comments received on the
NPRM and the FAA’s response to each
comment.
Request to Correct Left- and Right-Side
References in Figures
Delta requested that an exception be
added to paragraph (h) of the proposed
AD to correct mis-labeled figures and
part numbers. Delta stated that figures
have been labeled as being for the righthand side when the figures actually
shows the left-hand side. Delta also
provided a table of the part numbers as
identified in the service information and
what the correct part number should be.
Delta stated that it found these errors
while accomplishing the proposed
requirements, sent the information to
Airbus Canada, and received
confirmation from Airbus Canada of the
errors and that the errors would be fixed
in a later revision of service
information. Delta proposed language to
be inserted into the proposed AD and
included the phrase ‘‘or later revision’’
to allow use of service information
containing the correct location and part
numbers.
The FAA agrees to add paragraph
(h)(4) and table 1 to this AD to specify
the errors and provide the correct
location and part number information.
The FAA also agrees to allow use of
later approved service information, as
explained under ‘‘Request to Allow Use
of Later Revision of Service
Information’’ of this final rule.
Request to Allow Use of Later Revision
of Service Information
Delta requested that the proposed AD
be revised to allow ‘‘or later revisions of
the service information required by the
MCAI.’’ Delta explained that it
anticipates the release of a new revision
that contains corrections discussed
above.
The FAA agrees. The FAA has
coordinated with Transport Canada and
added a new exception in paragraph
(h)(5) of this AD.
Request To Add an Exception That
Defines Inspection Area
Delta requested adding an exception
to paragraph (h) of the proposed AD that
would more narrowly define the
inspection area described by paragraph
B. of Transport Canada AD CF–2023–20.
Delta stated that paragraph B. of
Transport Canada AD CF–2023–20 is
vague and implies a wider inspection
PO 00000
Frm 00024
Fmt 4700
Sfmt 4700
area than that defined by Airbus Canada
Service Bulletin BD500–240012, Issue
003, dated March 17, 2023.
The FAA disagrees. Paragraph B. of
Transport Canada AD CF–2023–20
refers to ‘‘inspected harnesses,’’ which
narrows the affected area to the
specified harnesses that were inspected
using the specifications of Paragraph A
of Transport Canada AD CF–2023–20.
Paragraph A of Transport Canada AD
CF–2023–20 specifies using the
inspection procedures described in
Airbus Canada Service Bulletin BD500–
240012, Issue 003, dated March 17,
2023. The FAA has not revised this AD
in this regard.
Additional Changes Made to This Final
Rule
References to an inspection report,
which were inadvertently included in
the preamble of the NPRM, have been
removed from this final rule.
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, considered
the comments received, 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, and any other
changes described previously, 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
Transport Canada AD CF–2023–20
specifies procedures for inspecting
certain wiring harnesses for damage and
clearance to adjacent structure and
corrective actions. Corrective actions
include adjustment of wiring harnesses,
replacing damaged braid sleeves, and
contacting the manufacturer for repair
instructions for worn or damaged
harnesses. 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 157 airplanes of U.S. registry.
The FAA estimates the following costs
to comply with this AD:

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.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2022–25–18,
Amendment 39–22274 (87 FR 75915,
December 12, 2022; corrected December
27, 2022 (87 FR 79236)) (AD 2022–25–
18). AD 2022–25–18 applied to certain
BAE Systems (Operations) Limited
Model BAe 146 and Model Avro 146–
RJ series airplanes. AD 2022–25–18
required repetitive inspections for
cracking of the MLG side stay outer link
and replacement if necessary. The FAA
issued AD 2022–25–18 to address
cracking on the shoulders of an MLG
side stay outer link. The unsafe
condition, if not addressed, could lead
to failure of the MLG side stay outer link
and MLG collapse, which could result
in a runway departure and the engine or
wing contacting the ground. The engine
or wing contacting the ground could
result in damage to the airplane, an
increased risk of fire, the airplane
flipping, and injury to occupants.
The NPRM published in the Federal
Register on December 27, 2023 (88 FR
89339). The NPRM was prompted by
AD G–2023–0004R1, dated November
16, 2023 (U.K. CAA AD G–2023–004R1)
(also referred to as the MCAI), issued by
U.K. CAA, which is the aviation
authority for the United Kingdom. The
MCAI states that further investigation
resulted in a reduced repetitive detailed
visual inspection interval and an option
to do repetitive special detailed
inspections; a new requirement for a
one-time dimensional tolerance check;
and a requirement to perform a
repetitive lubrication of the MLG side
stay outer link pivot.
In the NPRM, the FAA proposed to
require a reduction of the repetitive
visual inspection interval, provide
optional repetitive special detailed
inspections, and require accomplishing
a one-off dimensional tolerance check
and performing a repetitive lubrication
of the MLG side stay outer link pivot, as
specified in U.K. CAA AD G–2023–
0004R1. The FAA is issuing this AD to
address the unsafe condition on these
products.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-
1A11 airplanes. This AD was prompted by a report of multiple
occurrences of low clearance or fouling between certain wiring
harnesses and a hydraulic bracket and structure in the wing trailing
edge area that were detected on the production line. This AD requires
inspecting certain wiring harnesses for any damage and clearance to
adjacent structure and corrective actions, as specified in a Transport
Canada 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 by adding an AD that would apply to certain Airbus Canada
Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. The
NPRM published in the Federal Register on October 27, 2023 (88 FR
73772). The NPRM was prompted by AD CF-2023-20, dated March 22, 2023,
issued by Transport Canada, which is the aviation authority for Canada
(Transport Canada AD CF-2023-20) (also referred to as the MCAI). The
MCAI states that multiple occurrences of low clearance or fouling
between certain wiring harnesses and a hydraulic bracket and structure
in the wing trailing edge area were detected on the production line.
These conditions were caused by an inappropriate distribution of slack
in the wiring harnesses. Low clearance or fouling between the wiring
harnesses and adjacent structure could result in wear of the harnesses
leading to electrical arcing. Arcing in the presence of a leak from the
hydraulic lines in the area could lead to a fire.
In the NPRM, the FAA proposed to require inspecting certain wiring
harnesses for any damage and clearance to adjacent structure and
corrective actions, as specified in Transport Canada AD CF-2023-20. The
NPRM also proposed to require an inspection report. 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-2023-2135.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from Delta Air Lines (Delta). The
following presents the comments received on the NPRM and the FAA's
response to each comment.
Request to Correct Left- and Right-Side References in Figures
Delta requested that an exception be added to paragraph (h) of the
proposed AD to correct mis-labeled figures and part numbers. Delta
stated that figures have been labeled as being for the right-hand side
when the figures actually shows the left-hand side. Delta also provided
a table of the part numbers as identified in the service information
and what the correct part number should be. Delta stated that it found
these errors while accomplishing the proposed requirements, sent the
information to Airbus Canada, and received confirmation from Airbus
Canada of the errors and that the errors would be fixed in a later
revision of service information. Delta proposed language to be inserted
into the proposed AD and included the phrase ``or later revision'' to
allow use of service information containing the correct location and
part numbers.
The FAA agrees to add paragraph (h)(4) and table 1 to this AD to
specify the errors and provide the correct location and part number
information. The FAA also agrees to allow use of later approved service
information, as explained under ``Request to Allow Use of Later
Revision of Service Information'' of this final rule.
Request to Allow Use of Later Revision of Service Information
Delta requested that the proposed AD be revised to allow ``or later
revisions of the service information required by the MCAI.'' Delta
explained that it anticipates the release of a new revision that
contains corrections discussed above.
The FAA agrees. The FAA has coordinated with Transport Canada and
added a new exception in paragraph (h)(5) of this AD.
Request To Add an Exception That Defines Inspection Area
Delta requested adding an exception to paragraph (h) of the
proposed AD that would more narrowly define the inspection area
described by paragraph B. of Transport Canada AD CF-2023-20. Delta
stated that paragraph B. of Transport Canada AD CF-2023-20 is vague and
implies a wider inspection area than that defined by Airbus Canada
Service Bulletin BD500-240012, Issue 003, dated March 17, 2023.
The FAA disagrees. Paragraph B. of Transport Canada AD CF-2023-20
refers to ``inspected harnesses,'' which narrows the affected area to
the specified harnesses that were inspected using the specifications of
Paragraph A of Transport Canada AD CF-2023-20. Paragraph A of Transport
Canada AD CF-2023-20 specifies using the inspection procedures
described in Airbus Canada Service Bulletin BD500-240012, Issue 003,
dated March 17, 2023. The FAA has not revised this AD in this regard.
Additional Changes Made to This Final Rule
References to an inspection report, which were inadvertently
included in the preamble of the NPRM, have been removed from this final
rule.
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, considered the
comments received, 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, and any other changes described previously, 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
Transport Canada AD CF-2023-20 specifies procedures for inspecting
certain wiring harnesses for damage and clearance to adjacent structure
and corrective actions. Corrective actions include adjustment of wiring
harnesses, replacing damaged braid sleeves, and contacting the
manufacturer for repair instructions for worn or damaged harnesses.
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 157 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
[[Page 27381]]
Estimated costs for required actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Up to 7 work-hours x $85 per hour = Up to $595............... $0 Up to $595 Up to $93,415
----------------------------------------------------------------------------------------------------------------
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.
