ACTION: Final rule. AGENCY: SUPPLEMENTARY INFORMATION: Background The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD–500–1A10 airplanes. This AD was prompted by reports the overwing emergency exit door (OWEED) escape line may be incorrectly routed. This AD requires inspecting the OWEED escape line and correcting the routing if required, 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. DATES: This AD is effective May 30, 2023. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of May 30, 2023. ADDRESSES: AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA–2022–1492; 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 address for Docket Operations is U.S. Department of Transportation, Docket Operations, M– 30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE, Washington, DC 20590. Material Incorporated by Reference: • For material incorporated by reference in this AD, contact Transport Canada, Transport Canada National SUMMARY: PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 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 airplanes. The NPRM published in the Federal Register on December 6, 2022 (87 FR 74522). The NPRM was prompted by AD CF–2022–51, dated August 30, 2022 (Transport Canada AD CF–2022–51), issued by Transport Canada, which is the aviation authority for Canada (also referred to as the MCAI). The MCAI states certain airplanes may have entered service with the OWEED escape line incorrectly routed, in a manner that would render it inoperable when needed. The OWEED escape line is used to facilitate passenger egress along the wings following a ditching event. It is possible for the OWEED escape line to be installed under the liner of the OWEED resulting in the escape line not deploying, which could cause possible injuries to passengers escaping over the wing following a ditching event. In the NPRM, the FAA proposed to require inspecting the OWEED escape line and correcting the routing if required, as specified in Transport Canada AD CF–2022–51. The FAA is issuing this AD to address he unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–1492. E:\FR\FM\24APR1.SGM 24APR1 24682 Federal Register / Vol. 88, No. 78 / Monday, April 24, 2023 / Rules and Regulations Discussion of Final Airworthiness Directive Comments The FAA received a comment from Air Line Pilots Association, International (ALPA) who supported the NPRM without change. The FAA received an additional comment from one commenter, Delta Air Lines (Delta). The following presents the comment received on the NPRM and the FAA’s response to each comment. Request for Correction of Service Bulletin Delta commented that step 2.3.4 in the Accomplishment Instructions of Airbus Canada Limited Partnership Service Bulletin BD500–256005 Issue 001 dated 14 April 2020, contains a typographical error. Delta noted that step 2.3.4 states ‘‘Torque the screws (2) to 25 to 30 lbf·in. (2.82 to 3.39 Nm) (refer to AMP BD500–A–J20–31–00– 00AAA–711A–A).’’ Delta stated that Airbus Canada confirmed that the ‘‘(2)’’ reference is incorrect and should be ‘‘(1).’’ Delta added that ‘‘screws (2)’’ do not exist and are not identified in any other step or figure in Airbus Canada Limited Partnership Service Bulletin BD500–256005 Issue 001 dated 14 April 2020. The FAA agrees and confirmed with Airbus Canada Limited Partnership that this is a typographical error and the correct reference in step 2.3.4 is ‘‘(1).’’ The FAA added paragraph (h)(2) to this AD to allow using the correct reference for the step. 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–2022–51 specifies procedures for doing a detailed inspection of the OWEED escape line routing and correcting the OWEED escape line routing, if required. 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 ADDRESSES section. Costs of Compliance The FAA estimates that this AD affects 4 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 1.5 work-hours × $85 per hour = $128 ....................................................................................... $0 $128 $512 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: ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 1 work-hour × $85 per hour = $85 .......................................................................................................................... $0 $85 ddrumheller on DSK120RN23PROD with RULES1 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 VerDate Sep<11>2014 16:32 Apr 21, 2023 Jkt 259001 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.

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 airplanes. The NPRM published in 
the Federal Register on December 6, 2022 (87 FR 74522). The NPRM was 
prompted by AD CF-2022-51, dated August 30, 2022 (Transport Canada AD 
CF-2022-51), issued by Transport Canada, which is the aviation 
authority for Canada (also referred to as the MCAI). The MCAI states 
certain airplanes may have entered service with the OWEED escape line 
incorrectly routed, in a manner that would render it inoperable when 
needed. The OWEED escape line is used to facilitate passenger egress 
along the wings following a ditching event. It is possible for the 
OWEED escape line to be installed under the liner of the OWEED 
resulting in the escape line not deploying, which could cause possible 
injuries to passengers escaping over the wing following a ditching 
event.
    In the NPRM, the FAA proposed to require inspecting the OWEED 
escape line and correcting the routing if required, as specified in 
Transport Canada AD CF-2022-51. The FAA is issuing this AD to address 
he unsafe condition on these products.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1492.

Discussion of Final Airworthiness Directive

Comments

    The FAA received a comment from Air Line Pilots Association, 
International (ALPA) who supported the NPRM without change.
    The FAA received an additional comment from one commenter, Delta 
Air Lines (Delta). The following presents the comment received on the 
NPRM and the FAA's response to each comment.

Request for Correction of Service Bulletin

    Delta commented that step 2.3.4 in the Accomplishment Instructions 
of Airbus Canada Limited Partnership Service Bulletin BD500-256005 
Issue 001 dated 14 April 2020, contains a typographical error. Delta 
noted that step 2.3.4 states ``Torque the screws (2) to 25 to 30 
lbf[middot]in. (2.82 to 3.39 Nm) (refer to AMP BD500-A-J20-31-00-00AAA-
711A-A).'' Delta stated that Airbus Canada confirmed that the ``(2)'' 
reference is incorrect and should be ``(1).'' Delta added that ``screws 
(2)'' do not exist and are not identified in any other step or figure 
in Airbus Canada Limited Partnership Service Bulletin BD500-256005 
Issue 001 dated 14 April 2020.
    The FAA agrees and confirmed with Airbus Canada Limited Partnership 
that this is a typographical error and the correct reference in step 
2.3.4 is ``(1).'' The FAA added paragraph (h)(2) to this AD to allow 
using the correct reference for the step.

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

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.
