Abstract
The FAA is superseding Airworthiness Directive (AD) 2008-23- 01, which applies to certain Airbus SAS Model A318, A319, A320, and A321 series airplanes. AD 2008-23-01 required inspecting to determine the part number and serial number of the fuel tank boost pumps and, for airplanes with affected pumps, revising the operator's airplane flight manual (AFM) and FAA-approved maintenance program. AD 2008-23-01 also required modifying or replacing certain fuel tank boost pumps, which terminated the AFM limitations and the maintenance program revisions. Since the FAA issued AD 2008-23-01, it has been determined that airplanes fitted with a different fuel pump can be subject to cavitation erosion on the wiring conduit. This AD requires inspecting affected fuel pumps for discrepancies and replacement if necessary, as specified in a European Union Aviation Safety Agency (EASA). This AD also requires replacing certain other fuel pumps. This AD also limits the installation of affected fuel pumps under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2008-23-
01, which applies to certain Airbus SAS Model A318, A319, A320, and
A321 series airplanes. AD 2008-23-01 required inspecting to determine
the part number and serial number of the fuel tank boost pumps and, for
airplanes with affected pumps, revising the operator's airplane flight
manual (AFM) and FAA-approved maintenance program. AD 2008-23-01 also
required modifying or replacing certain fuel tank boost pumps, which
terminated the AFM limitations and the maintenance program revisions.
Since the FAA issued AD 2008-23-01, it has been determined that
airplanes fitted with a different fuel pump can be subject to
cavitation erosion on the wiring conduit. This AD requires inspecting
affected fuel pumps for discrepancies and replacement if necessary, as
specified in a European Union Aviation Safety Agency (EASA). This AD
also requires replacing certain other fuel pumps. This AD also limits
the installation of affected fuel pumps under certain conditions. The
FAA is issuing this AD to address the unsafe condition on these
products.
DATES: This AD is effective July 12, 2023.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of July 12,
2023.

Background
The FAA issued AD 2008-23-01, Amendment 39-15722 (73 FR 67379,
November 14, 2008) (AD 2008-23-01), for certain Airbus SAS Model A318-
111, -112, -121, and -122 airplanes; Model A319-111, -112, -113, -114,
-115, -131, -132, -133, -151N, -153N, and -171N airplanes; Model A320-
211, -212, -214, -216, -231, -232, -233, -251N, -252N, -253N, -271N, -
272N, and -273N airplanes; and Model A321-111, -112, -131, -211, -212,
-213, -231, -232, -251N, -252N, -253N, -271N, -272N, -251NX, -252NX, -
253NX, -271NX, and -272NX airplanes.
AD 2008-23-01 was prompted by an MCAI originated by EASA, which is
the Technical Agent for the Member States of the European Union. EASA
issued AD 2007-0218, dated August 10, 2007, to correct an unsafe
condition.
AD 2008-23-01 required inspecting to determine the part number and
serial number of the fuel tank boost pumps and, for airplanes with
affected pumps, revising the AFM and the FAA-approved maintenance
program. AD 2008-23-01 also required modifying or replacing the fuel
tank boost pumps (part numbers (P/Ns) 568-1-27202-001, 568-1-27202-002,
and 568-1-27202-005), which terminated the AFM limitations and the
maintenance program revisions. The FAA issued AD 2008-23-01 to address
electrical arcing in the fuel tank boost pump motor, which, in the
presence of a combustible air-fuel mixture in the pump, could result in
an explosion and loss of the airplane.
Actions Since AD 2008-23-01 Was Issued
Since the FAA issued AD 2008-23-01, EASA superseded AD 2007-0218R2,
dated October 10, 2014 (EASA AD 2007-0218R2), and issued EASA AD 2023-
0106, dated May 25, 2023 (EASA AD 2023-0106) (also referred to as the
MCAI), to correct an unsafe condition for all Model A318-111, -112, -
121, and -122 airplanes; Model A319-111, -112, -113, -114, -115, -131,
-132, -133, -151N, -153N, and -171N airplanes; Model A320-211, -212, -
214, -215, -216, -231, -232, -233, -251N, -252N, -253N, -271N, -272N,
and -273N airplanes; and Model A321-111, -112, -131, -211, -212, -213,
-231, -232, -251N, -252N, -253N, -271N, -272N, -251NX, -252NX, -253NX,
-271NX, and -272NX airplanes. Model A320-215 airplanes are not
certificated by the FAA and are not included on the U.S. type
certificate data sheet; this AD therefore does not include those
airplanes in the applicability. The MCAI states that since EASA AD
2007-0218R2 was issued to address fuel pump A (P/Ns 568-1-27202-001,
568-1-27202-002, and 568-1-27202-005), it has been determined that
airplanes equipped with fuel pump B (P/N 568-1-27202-02R, which is one
of the replacement fuel pumps for fuel pump A) can be subject to
cavitation erosion on the wiring conduit. This condition, if not
detected and mitigated, could lead to be the source of an in-tank
ignition, affecting the integrity of the airplane structure and
systems.
Paragraph (1) of EASA AD 2023-0106 prohibits operation of an
airplane equipped with fuel pump A. However, this AD does not include
that requirement. Instead, as specified in paragraph (h)(3) of this AD,
for airplanes equipped with fuel pump A, operators must, before further
flight, replace fuel pump A with a fuel pump other than
[[Page 41475]]
fuel pump A, except as specified in paragraphs (7) and (8) of EASA AD
2023-0106. Paragraph (j) of AD 2008-23-01 required the replacement or
modification of fuel pump A, which operators should have done within
5,000 flight hours or 18 months, whichever occurs first after December
19, 2008 (the effective date of AD 2008-23-01). Therefore, paragraph
(h)(3) of this AD continues to require the replacement of fuel pump A.
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-2023-1396.
Related Service Information Under 1 CFR Part 51
EASA AD 2023-0106 specifies procedures for doing a general visual
inspection of fuel pump B for discrepancies and replacement if
necessary. Discrepancies include any erosion on the wiring conduit,
holes in the inlet guide vanes, and erosion on the inlet guide vane
that is less than 12mm (0.47 in) from the outer edge to the start of
the erosion. EASA AD 2023-0106 also prohibits operation of an airplane
equipped with fuel pump A.
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.
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
referenced above. The FAA is issuing this AD after determining that the
unsafe condition described previously is likely to exist or develop on
other products of the same type design.
Requirements of This AD
This AD requires accomplishing the actions specified in EASA AD
2023-0106 described previously, except for any differences identified
as exceptions in the regulatory text of this AD. This AD also limits
the installation of affected fuel pumps under certain conditions.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has been
coordinating this process with manufacturers and CAAs. As a result,
EASA AD 2023-0106 is incorporated by reference in this AD. This AD
requires compliance with EASA AD 2023-0106 in its entirety through that
incorporation, except for any differences identified as exceptions in
the regulatory text of this AD. Using common terms that are the same as
the heading of a particular section in EASA AD 2023-0106 does not mean
that operators need comply only with that section. For example, where
the AD requirement refers to ``all required actions and compliance
times,'' compliance with this AD requirement is not limited to the
section titled ``Required Action(s) and Compliance Time(s)'' in EASA AD
2023-0106. Service information required by EASA AD 2023-0106 for
compliance will be available at <a href="http://regulations.gov">regulations.gov</a> under Docket No. FAA-
2023-1396 after this AD is published.
Interim Action
The FAA considers that this AD is an interim action and further AD
action might follow.
FAA's Justification and Determination of the Effective Date
Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and
comment procedures for rules when the agency, for ``good cause,'' finds
that those procedures are ``impracticable, unnecessary, or contrary to
the public interest.'' Under this section, an agency, upon finding good
cause, may issue a final rule without providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies forgoing notice and comment prior to adoption of this rule
because airplanes fitted with fuel pump B are subject to cavitation
erosion on the wiring conduit, which could lead to be the source of an
in-tank ignition, affecting the integrity of the airplane structure and
systems. In addition, the required inspection must be done within 30 or
90 days, depending on fuel pump location, in order to address the
unsafe condition. Accordingly, notice and opportunity for prior public
comment are impracticable and contrary to the public interest pursuant
to 5 U.S.C. 553(b)(3)(B).
In addition, the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in less than 30 days,
for the same reasons the FAA found good cause to forgo notice and
comment.
Regulatory Flexibility Act (RFA)
The requirements of the RFA do not apply when an agency finds good
cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and
comment. Because the FAA has determined that it has good cause to adopt
this rule without notice and comment, RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 1,899 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action * Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
New actions......................... 1 work-hour x $85 per $0 $85 $161,415
hour = $85.
----------------------------------------------------------------------------------------------------------------
* U.S. operators have already replaced fuel pump A; therefore the costs are not included in this table. For any
affected airplane that is imported and placed on the U.S. Register in the future that has not done the
replacement, refer to the cost estimates in the ``Estimated costs on on-condition actions'' table below, which
specifies replacement costs.
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
[[Page 41476]]
number of aircraft that might need this on-condition action:
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
3 work-hours x $85 per hour = $255.... $6,625 $6,880
------------------------------------------------------------------------
According to the manufacturer, some or all of the costs of this AD
may be covered under warranty, thereby reducing the cost impact on
affected operators. The FAA does not control warranty coverage for
affected operators. As a result, the FAA has included all known costs
in the cost estimate.
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, and
(2) Will not affect intrastate aviation in Alaska.

the manager of the responsible Flight Standards Office.
[[Page 41477]]
(2) Contacting the Manufacturer: For any requirement in this AD
to obtain instructions from a manufacturer, the instructions must be
accomplished using a method approved by the Manager, International
Validation Branch, FAA; or EASA; or Airbus SAS's EASA Design
Organization Approval (DOA). If approved by the DOA, the approval
must include the DOA-authorized signature.
(3) Required for Compliance (RC): Except as required by
paragraph (i)(2) of this AD, if any service information referenced
in EASA AD 2023-0106 contains paragraphs that are labeled as RC, the
instructions in RC paragraphs, including subparagraphs under an RC
paragraph, must be done to comply with this AD; any paragraphs,
including subparagraphs under those paragraphs, that are not
identified as RC are recommended. The instructions in paragraphs,
including subparagraphs under those paragraphs, not identified as RC
may be deviated from using accepted methods in accordance with the
operator's maintenance or inspection program without obtaining
approval of an AMOC, provided the instructions identified as RC can
be done and the airplane can be put back in an airworthy condition.
Any substitutions or changes to instructions identified as RC
require approval of an AMOC.
(j) Additional Information
