SUPPLEMENTARY INFORMATION:
[[Page 93158]]
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to supersede AD 2023-05-08, Amendment 39-22377 (88 FR
20751, April 7, 2023) (AD 2023-05-08). AD 2023-05-08 applied to certain
Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11
airplanes. AD 2023-05-08 required revising the existing maintenance or
inspection program, as applicable, to incorporate new or more
restrictive airworthiness limitations. The FAA issued AD 2023-05-08 to
address reduced structural integrity of the airplane or reduced
controllability of the airplane.
The NPRM published in the Federal Register on April 29, 2024 (89 FR
33300). The NPRM was prompted by AD CF-2023-69, dated October 5, 2023,
issued by Transport Canada, which is the aviation authority for Canada
(Transport Canada AD CF-2023-69) (also referred to as the MCAI).
In the NPRM, the FAA proposed to 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 issuing this AD to
address the unsafe condition on these products.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2024-1285.
Discussion of Final Airworthiness Directive
Comments
The FAA received comments from Air Line Pilots Association,
International (ALPA), who supported the NPRM without change.
The FAA received additional 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 Incorporate by Reference the MCAI
Delta requested that the FAA update the language in the proposed AD
to mandate Transport Canada AD CF-2023-69 via incorporation by
reference (IBR) instead of mandating Airbus Canada Limited Partnership
A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue 017.01,
dated August 17, 2023, by IBR. Delta stated this would allow operators
to incorporate the following language: ``The use of superseding Interim
Revisions or later revisions of the AWL Publication, approved by TC, is
acceptable for compliance [. . .]'' in Transport Canada AD CF-2023-69.
Delta noted that transitioning to IBR of the Transport Canada AD versus
the IBR of a specific manufacturer airworthiness limitation (AWL)
revision is necessary as AWL Issue 017.02 has already been published
and AWL Issue 018.00 is estimated to be released later in 2024. Delta
noted it could be at risk of grounding its fleet while waiting for an
alternative method of compliance (AMOC) to allow incorporating more up
to date AWL revisions.
The FAA agrees to mandate Transport Canada AD CF-2023-69 via IBR in
this AD for the reasons provided by the commenter. Incorporating by
reference the MCAI instead of the service information does not change
the required action to incorporate Airbus Canada Limited Partnership
A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue 017.01,
dated August 17, 2023, into their maintenance or inspection program.
Instead incorporating by reference of the MCAI relieves the burden of
applying for AMOCs to use later approved revisions of the service
information. By mandating Transport Canada AD CF-2023-69 via IBR,
operators are allowed to use applicable later AWL revisions to comply
with the requirements of this AD. Transport Canada AD CF-2023-69
includes paragraph C., which accepts the use of later revisions,
approved by Transport Canada, of the referenced AWL document for
compliance. The FAA concurs this change will minimize any disruption to
an operator's existing maintenance or inspection program due to any
potential delays in an AMOC approval.
The FAA has revised paragraph (k) of this AD to incorporate by
reference Transport Canada AD CF-2023-69 and added paragraph (l) to
this AD to specify exceptions to Transport Canada AD CF-2023-69. The
exceptions in paragraph (l) of this AD are standard for ADs that
incorporate MCAI by reference.
The FAA has also revised paragraph (m) of this AD (paragraph (l) of
the proposed AD) to refer to Transport Canada AD CF-2023-69.
Although Delta indicated that all of Airbus Canada Limited
Partnership A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue
017.01, dated August 17, 2023, should be mandated via the IBR of
Transport Canada AD CF-2023-69, the FAA has still excluded Section 03,
``Candidate CMR Limitations--General.'' Paragraph (g) of this AD is for
the CCMRs and paragraph (k) of this AD incorporates all AWLs except for
CCMRs, as specified in the paragraph (l)(3) of this AD.
Request To Allow AMOCs
Delta requested that the FAA add a paragraph to allow the use of
AMOCs approved for AD 2023-05-08 as AMOCs to the proposed AD paragraphs
that require revising the existing maintenance or inspection program.
Delta stated it has received many AMOCs for AD 2023-05-08, including
one that approves the use of A220 AWL Issue 017.02, or later revisions
approved by Transport Canada or Airbus Canada Limited Partnership's
Transport Canada Design Approval Organization (DAO), except for the use
of candidate certification maintenance requirements (CCMRs). Delta
noted that the CCMRs in Table 2 of Airbus Canada Limited Partnership
A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue 011.00,
dated June 18, 2020, are still mandatory for airplanes with an original
certificate of airworthiness issued on or before June 18, 2020. Delta
concluded that the extension of these AMOCs to the proposed AD would
allow Delta to continue to use the latest AWL revision and not be
responsible for requesting/receiving an AMOC between the AD's
publication date and the AD's effective date, preventing the grounding
of its fleet.
The FAA agrees that previous AMOCs are acceptable for certain
paragraphs in this AD. The FAA has added paragraph (n)(1)(ii) to this
AD to allow AMOCs approved previously for AD 2023-05-08 as AMOCs for
the corresponding provisions of paragraphs (g) and (i) of this AD. The
FAA has also added paragraph (n)(1)(iii) to this AD to allow AMOCs
approved previously for AD 2023-05-08 as AMOCs for the corresponding
provisions of paragraph (k) of this AD, except for AMOCs that allow the
use of revisions earlier than Airbus Canada Limited Partnership A220
Airworthiness Limitations, BD500-3AB48-11400-02, Issue 017.01, dated
August 17, 2023.
Request To Remove the Requirement Mandating CCMRs
Delta requested that the FAA remove the requirement mandating the
CCMR section of the AWL document. Delta noted that new airplanes are
required by the CFR to have the corresponding AWL revision incorporated
into their maintenance program. Delta stated the A220 AWL revisions
have a CCMR section and thus are required to be incorporated into its
maintenance program. Delta pointed out that the FAA has stated CCMR
sections should not be mandated by the FAA (as specified in the FAA's
response to comments to the NPRM for AD 2023-05-08). Delta
[[Page 93159]]
concluded their maintenance program is split as follows:
<bullet> Newly delivered airplanes: not affected by an AD, CCMRs
are required.
<bullet> Airplanes delivered after AWL Issue 011.00: CCMR are not
required per ADs or CFR.
<bullet> Airplanes delivered before AWL Issue 011.00: CCMRs are
required per ADs.
The FAA agrees to clarify. In AD 2023-05-08, the FAA explained that
equivalent airplane maintenance manual (AMM) tasks may be mandated in
lieu of CCMRs in future rulemaking. The FAA also explained that CCMRs
that were previously mandated can continue to be mandated. This AD only
mandates the previously mandated CCMRs from AD 2021-04-05, Amendment
39-21426 (86 FR 10799, February 23, 2021), as specified in the retained
requirements of paragraph (g) of this AD. For this AD, there are no new
CCMRs. For future rulemaking where the MCAI includes new CCMRs, the FAA
will mandate equivalent AMM tasks in lieu of the CCMRs.
Regarding Delta's comment that their maintenance program is split,
the FAA notes that, for Model BD-500-1A10 and BD-500-1A11 airplanes,
the CCMRs are mandated either by an AD action or the CFR as follows:
<bullet> Newly delivered airplanes with an original airworthiness
certificate or original export certificate of airworthiness issued
after August 17, 2023: These airplanes are not affected by this AD.
However, complying with the airworthiness limitations specified as part
of the approved type design and referenced on the type certificate data
sheet is required per the CFR (14 CFR 91.403(c)). These airplanes were
certified with AWL documents that include CCMRs.
<bullet> Airplanes delivered after AWL Issue 011.00 (airplane with
an original airworthiness certificate or original export certificate of
airworthiness issued after June 18, 2020, but on or before August 17,
2023): These airplanes are affected by this AD. This AD does not
require incorporating CCMRs for these airplanes but the CCMRs in the
AWL delivered with the airplane are required by the CFR. These
airplanes must comply with the airworthiness limitations specified as
part of the approved type design and referenced on the type certificate
data sheet; these airplanes were certified with AWL Issue 011.00 (or
later issues). Those AWL issues include the CCMRs that operators must
comply with.
<bullet> Airplanes delivered before AWL Issue 011.00 (airplanes
with an original airworthiness certificate or original export
certificate of airworthiness issued on or before June 18, 2020) are
affected by this AD, which requires the CCMRs.
The FAA has not changed this AD regarding this issue.
Request To Add Exception Paragraph
Delta requested that the FAA add an exception paragraph to the
proposed AD to allow FAA operators to omit the 10,000-flight hour life
limit for the fuel pump cartridge. In addition, Delta requested that
Airbus Canada's latest petition (submitted Dec. 2023) to update
Exemption 16779A be approved. Delta noted that the FAA has published
Docket No.: FAA-2016-4198; Summary Notice No. 2024-18, which summarizes
the petition to request relief from the 10,000-flight hour life limit
for the fuel pump cartridge.
Delta stated that in Airbus Canada Limited Partnership A220
Airworthiness Limitations, BD500-3AB48-11400-02, Issue 017.00, Airbus
Canada removed, for European Union Aviation Safety Agency (EASA) and
Transport Canada operators, the 13,000 flight hour life limit for all
fuel boost pump cartridges with manufacturer part number (MPN) 9C208-3
except for ``SN AAM4613 to AAM4622; AAF8325; AAF8326; AAJ6639; AAK5612;
AAL6169; AAL6170; AAL6173; AAL6174 (PRE SB 9C208-3-28-001)''. Delta
stated that Airbus Canada was not able to remove the 10,000-flight hour
life limit for FAA operators as FAA Exemption 16779A still requires it.
Delta explained that these fuel boost pump cartridges, MPN 9C208-3,
cost approximately $85,000/pump, and there are two pumps per airplane.
In addition, Delta explained that it takes approximately 3 years to
reach the 10,000-flight hour life limit. At its present fleet size,
Delta estimated that it must spend a minimum of $11.7 million every 3
years to replace the fuel boost pump cartridges and once its fleet is
fully delivered, it will spend approximately $24.6 million every 3
years. Delta concluded that it is unreasonable to force FAA operators
to be burdened with additional costs of compliance over that of other
operators who are operating under Airbus Canada Limited Partnership
A220 Airworthiness Limitations, BD500-3AB48-11400-02, Issue No. 017.00.
Delta proposed that the FAA include the following exception to
paragraph (l) of the proposed AD: ``Where TCCA AD CF-2023-69 paragraph
A. requires incorporation of the AWL, this AD does not require a 10,000
FH life limit on Part Number 9C208-3 (Cartridge, boost pump) unless it
falls within the effectivity definition in Parker SB 9C208-3-28-001.''
Delta requested that if the FAA does not agree to add an exception
as stated above, then the Costs of Compliance section of the NPRM be
updated to include these exceptional material costs.
The FAA does not agree with the commenter's requests. The FAA
cannot grant or deny petitions for exemptions within an AD as that
process is outside the scope of this AD action. In addition, the FAA
has determined that this AD cannot include relief from the fuel boost
pump cartridge life limits in an AD in regards to the petition for
relief from FAA Exemption 16779A.
Regarding the costs, the FAA does not agree to revise the Cost of
Compliance section of this AD to include the cost of accomplishing
repetitive replacements. The FAA recognizes such costs are part of
complying with airworthiness limitations, but the costs of
accomplishing maintenance actions specified in airworthiness
limitations are not directly required by this AD. Instead, this AD
requires operators to revise their existing maintenance or inspection
program, as applicable, to incorporate the new airworthiness
limitations. Compliance with any airworthiness limitation is required
by 14 CFR 91.403(c). Therefore, compliance with the airworthiness
limitations is not a requirement of this AD, and including the cost of
a replacement part would be inappropriate. The FAA has not changed this
AD regarding this issue.
Request To Clarify AMOC Process
Delta requested clarification if an AMOC to deviate from the
proposed AD (once published as a final rule) will be needed or if U.S.
operators will be able to deviate from the life limit for certain fuel
boost pump cartridges once the petition to exemption 16779A is
published. Delta stated it believes this exemption will allow Airbus
Canada to remove the life limit from the AWL at the next revision.
Delta stated it may need to continue to comply with the specific AWL
revision until the next AWL revision is published and the FAA has
provided approval to use the latest AWL. Delta concluded that due to
the significant operational and financial impacts, Delta would like to
introduce this relief as soon as possible.
The FAA agrees to clarify. Once the petition to the exemption
16779A is approved and published, operators may request an AMOC to this
AD, under the provisions of paragraph (n)(1) of this AD, to allow
relief from the fuel boost pump cartridge life limits.

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.
Material Incorporated by Reference Under 1 CFR Part 51
Transport Canada AD CF-2023-69 describes airworthiness limitations
for fuel tank systems, safe life limits, and certification maintenance
requirements.
This AD also requires 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 AD also requires 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 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 99 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this 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
FAA estimates the total cost per operator for the new 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
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.
