Background The FAA issued AD 2023–05–08, Amendment 39–22377 (88 FR 20751, April 7, 2023) (AD 2023–05–08), for certain Airbus Canada Limited Partnership Model BD–500–1A10 and BD–500–1A11 airplanes. AD 2023–05– 08 requires revising the existing maintenance or inspection program, as E:\FR\FM\29APP1.SGM 29APP1 Federal Register / Vol. 89, No. 83 / Monday, April 29, 2024 / Proposed Rules applicable, to incorporate new or more restrictive airworthiness limitations. AD 2023–05–08 resulted from a determination that new or more restrictive airworthiness limitations are necessary. The FAA issued AD 2023– 05–08 to supersede AD 2021–04–05, Amendment 39–21426 (86 FR 10799, February 23, 2021). AD 2023–05–08 terminated the actions specified in AD 2021–04–05, except for Section 03, ‘‘Candidate CMR Limitations— General’’, of Airbus Canada Limited Partnership A220 Airworthiness Limitations, BD500–3AB48–11400–02, Issue 011.00, dated June 18, 2020. The FAA issued AD 2023–05–08 to address reduced structural integrity of the airplane or reduced controllability of the airplane. khammond on DSKJM1Z7X2PROD with PROPOSALS Actions Since AD 2023–05–08 Was Issued Since the FAA issued AD 2023–05– 08, the FAA has determined that new or more restrictive airworthiness limitations are necessary. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued TCCA AD CF– 2023–69, dated October 5, 2023 (TCCA AD CF–2022–18) (also referred to after this as the MCAI), to correct an unsafe condition for certain Airbus Canada Limited Partnership Model BD–500– 1A10 and BD–500–1A11 airplanes. Airplanes with an original airworthiness certificate or original export certificate of airworthiness issued after August 17, 2023, must comply with the airworthiness limitations specified as part of the approved type design and referenced on the type certificate data sheet; this proposed AD therefore does not include those airplanes in the applicability. The FAA is proposing this AD to address new or more restrictive airworthiness limitations are necessary. The FAA is proposing this AD to address reduced structural integrity of the airplane or reduced controllability of the airplane. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2024–1285. Related Service Information Under 1 CFR Part 51 Airbus Canada Limited Partnership has issued A220 Airworthiness Limitations, BD500–3AB48–11400–02, Issue 017.01, dated August 17, 2023, which describes airworthiness limitations for fuel tank systems, safe life limits, and certification maintenance requirements. This proposed AD would also require Airbus Canada Limited Partnership VerDate Sep<11>2014 16:16 Apr 26, 2024 Jkt 262001 A220 Airworthiness Limitations, BD500–3AB48–11400–02, Issue 014.00, dated February 3, 2022, which the Director of the Federal Register approved for incorporation by reference as of May 12, 2023 (88 FR 20751, April 7, 2023). This proposed AD would also require Airbus Canada Limited Partnership A220 Airworthiness Limitations, BD500–3AB48–11400–02, Issue 011.00, dated June 18, 2020, which the Director of the Federal Register approved for incorporation by reference as of March 30, 2021 (86 FR 10799, February 23, 2021). This service information 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. FAA’s Determination 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 [and service information] referenced above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop on other products of the same type design. Proposed Requirements of This NPRM This proposed AD would retain all requirements of AD 2023–05–08, which includes retaining Section 03, ‘‘Candidate CMR Limitations— General,’’ of Airbus Canada Limited Partnership A220 Airworthiness Limitations, BD500–3AB48–11400–02, Issue 011.00, dated June 18, 2020. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Revising the existing maintenance or inspection program as proposed in this AD would terminate the retained requirements from AD 2023–05–08 that are specified in paragraph (i) of this proposed AD. This proposed AD would require revisions to certain operator maintenance documents to include new actions (e.g., inspections) and Critical Design Configuration Control Limitations (CDCCLs). Compliance with these actions and CDCCLs is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator may not be able to accomplish the actions PO 00000 Frm 00014 Fmt 4702 Sfmt 4702 33301 described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (m)(1) of this proposed AD. Differences Between This NPRM and the MCAI or Service Information TCCA AD CF–2023–69 specifies to incorporate all sections of the airworthiness limitations document. This proposed AD would not require the incorporation of Section 03, ‘‘Candidate CMR limitations,’’ of Airbus Canada Limited Partnership A220 Airworthiness Limitations, BD500– 3AB48–11400–02, Issue 017.01, dated August 17, 2023. However, this proposed AD would continue to require the incorporation of Section 03, ‘‘Candidate CMR limitations—General,’’ of Airbus Canada Limited Partnership A220 Airworthiness Limitations, BD500–3AB48–11400–02, Issue 011.00, dated June 18, 2020, which is identical to the list of CCMRs identified in Issue 017.01. Costs of Compliance The FAA estimates that this proposed AD affects 99 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: The FAA estimates the total cost per operator for the retained actions from AD 2023–05–08 to be $7,650 (90 workhours × $85 per work-hour). The FAA has determined that revising the maintenance or inspection program takes an average of 90 work-hours per operator, although the agency recognizes that this number may vary from operator to operator. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, the agency estimates the average total cost per operator to be $7,650 (90 work-hours × $85 per work-hour). The FAA estimates the total cost per operator for the new proposed actions to be $7,650 (90 work-hours × $85 per work-hour). 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 E:\FR\FM\29APP1.SGM 29APP1 33302 Federal Register / Vol. 89, No. 83 / Monday, April 29, 2024 / Proposed Rules 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 The FAA determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Would not affect intrastate aviation in Alaska, and (3) Would 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 Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

RIN 2120-AA64


Airworthiness Directives; Airbus Canada Limited Partnership (Type 
Certificate Previously Held by C Series Aircraft Limited Partnership 
(CSALP); Bombardier, Inc.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2023-05-08, which applies to certain Airbus Canada Limited Partnership 
Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2023-05-08 requires 
required revising the existing maintenance or inspection program, as 
applicable, to incorporate new or more restrictive airworthiness 
limitations. Since the FAA issued AD 2023-05-08, the FAA has determined 
that new or more restrictive airworthiness limitations are necessary. 
This proposed AD would continue to require certain actions in AD 2023-
05-08 and require revising the existing maintenance or inspection 
program, as applicable, to incorporate new or more restrictive 
airworthiness limitations. The FAA is proposing this AD to address the 
unsafe condition on these products.

this rulemaking.

Background

    The FAA issued AD 2023-05-08, Amendment 39-22377 (88 FR 20751, 
April 7, 2023) (AD 2023-05-08), for certain Airbus Canada Limited 
Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2023-05-08 
requires revising the existing maintenance or inspection program, as

[[Page 33301]]

applicable, to incorporate new or more restrictive airworthiness 
limitations. AD 2023-05-08 resulted from a determination that new or 
more restrictive airworthiness limitations are necessary. The FAA 
issued AD 2023-05-08 to supersede AD 2021-04-05, Amendment 39-21426 (86 
FR 10799, February 23, 2021). AD 2023-05-08 terminated the actions 
specified in AD 2021-04-05, except for Section 03, ``Candidate CMR 
Limitations--General'', of Airbus Canada Limited Partnership A220 
Airworthiness Limitations, BD500-3AB48-11400-02, Issue 011.00, dated 
June 18, 2020. The FAA issued AD 2023-05-08 to address reduced 
structural integrity of the airplane or reduced controllability of the 
airplane.

Actions Since AD 2023-05-08 Was Issued

    Since the FAA issued AD 2023-05-08, the FAA has determined that new 
or more restrictive airworthiness limitations are necessary.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued TCCA AD CF-2023-69, dated October 5, 
2023 (TCCA AD CF-2022-18) (also referred to after this as the MCAI), to 
correct an unsafe condition for certain Airbus Canada Limited 
Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. Airplanes with 
an original airworthiness certificate or original export certificate of 
airworthiness issued after August 17, 2023, must comply with the 
airworthiness limitations specified as part of the approved type design 
and referenced on the type certificate data sheet; this proposed AD 
therefore does not include those airplanes in the applicability.
    The FAA is proposing this AD to address new or more restrictive 
airworthiness limitations are necessary. The FAA is proposing this AD 
to address reduced structural integrity of the airplane or reduced 
controllability of the airplane.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2024-1285.

Related Service Information Under 1 CFR Part 51

    Airbus Canada Limited Partnership has issued A220 Airworthiness 
Limitations, BD500-3AB48-11400-02, Issue 017.01, dated August 17, 2023, 
which describes airworthiness limitations for fuel tank systems, safe 
life limits, and certification maintenance requirements.
    This proposed AD would also require Airbus Canada Limited 
Partnership A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue 
014.00, dated February 3, 2022, which the Director of the Federal 
Register approved for incorporation by reference as of May 12, 2023 (88 
FR 20751, April 7, 2023).
    This proposed AD would also require Airbus Canada Limited 
Partnership A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue 
011.00, dated June 18, 2020, which the Director of the Federal Register 
approved for incorporation by reference as of March 30, 2021 (86 FR 
10799, February 23, 2021).
    This service information 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.

FAA's Determination

    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 
[and service information] referenced above. The FAA is issuing this 
NPRM after determining that the unsafe condition described previously 
is likely to exist or develop on other products of the same type 
design.

Proposed Requirements of This NPRM

    This proposed AD would retain all requirements of AD 2023-05-08, 
which includes retaining Section 03, ``Candidate CMR Limitations--
General,'' of Airbus Canada Limited Partnership A220 Airworthiness 
Limitations, BD500-3AB48-11400-02, Issue 011.00, dated June 18, 2020. 
This proposed AD would require revising the existing maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive airworthiness limitations. Revising the existing 
maintenance or inspection program as proposed in this AD would 
terminate the retained requirements from AD 2023-05-08 that are 
specified in paragraph (i) of this proposed AD.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections) and 
Critical Design Configuration Control Limitations (CDCCLs). Compliance 
with these actions and CDCCLs is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed AD, the operator may not be able 
to accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval for an alternative method of compliance according to paragraph 
(m)(1) of this proposed AD.

Differences Between This NPRM and the MCAI or Service Information

    TCCA AD CF-2023-69 specifies to incorporate all sections of the 
airworthiness limitations document. This proposed AD would not require 
the incorporation of Section 03, ``Candidate CMR limitations,'' of 
Airbus Canada Limited Partnership A220 Airworthiness Limitations, 
BD500-3AB48-11400-02, Issue 017.01, dated August 17, 2023. However, 
this proposed AD would continue to require the incorporation of Section 
03, ``Candidate CMR limitations--General,'' of Airbus Canada Limited 
Partnership A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue 
011.00, dated June 18, 2020, which is identical to the list of CCMRs 
identified in Issue 017.01.

Costs of Compliance

    The FAA estimates that this proposed AD affects 99 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD 2023-05-08 to be $7,650 (90 work-hours x $85 per work-
hour).
    The FAA has determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although the 
agency recognizes that this number may vary from operator to operator. 
Since operators incorporate maintenance or inspection program changes 
for their affected fleet(s), the FAA has determined that a per-operator 
estimate is more accurate than a per-airplane estimate. Therefore, the 
agency estimates the average total cost per operator to be $7,650 (90 
work-hours x $85 per work-hour).
    The FAA estimates the total cost per operator for the new proposed 
actions to be $7,650 (90 work-hours x $85 per work-hour).

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

[[Page 33302]]

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

    The FAA determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
