SUPPLEMENTARY INFORMATION: Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA Emergency AD 2021–0115–E, dated April 23, 2021 (EASA AD 2021–0115–E) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all Airbus SAS Model A318, A319, A320, and A321 series airplanes. Model A320–215 airplanes, which are listed in the applicability of EASA AD 2021– 0115–E, 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. This AD was prompted by the identification of a potential quality issue found in the fuel pump that includes a locking key of the impeller drive shaft found loose in the cavity under the impeller. Incorrect installation of the locking key combined with a pump operation not fully immersed in fuel could compromise the fuel pump integrity. The FAA is issuing this AD to address this condition, which, in the case of operating a pump while not fully immersed in fuel, could create an ignition source in the fuel tank, and result in a fuel tank explosion and consequent loss of the airplane. See the PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 MCAI for additional background information. Related Service Information Under 1 CFR Part 51 EASA AD 2021–0115–E specifies procedures for replacement of affected fuel pumps. 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 the State of Design Authority, the FAA has been notified of the unsafe condition described in the MCAI referenced above. The FAA is issuing this AD because the FAA evaluated all pertinent information and determined the unsafe condition exists and 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 2021– 0115–E described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD. The service information referenced in EASA AD 2021–0115–E includes a number of ‘‘RC’’ (required for compliance) steps. This AD, however, does not require those RC steps, and requires that the replacement be done as specified in paragraph (h)(2) of this AD. The service information referenced in EASA AD 2021–0115–E specifies reporting certain information and sending affected fuel pumps to the manufacturer. Those actions are not required by this AD, although the FAA recommends that those actions be performed as identified in the service information. Explanation of Required Compliance Information In the FAA’s ongoing efforts to improve the efficiency of the AD process, the FAA initially worked with Airbus and EASA to develop a process to use certain EASA ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has since coordinated with other manufacturers and civil aviation authorities (CAAs) to use this process. As a result, EASA AD 2021–0115–E is incorporated by reference in this final rule. This AD, E:\FR\FM\29APR1.SGM 29APR1 22585 Federal Register / Vol. 86, No. 81 / Thursday, April 29, 2021 / Rules and Regulations therefore, requires compliance with EASA AD 2021–0115–E 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 the EASA AD 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 the EASA AD. Service information specified in EASA AD 2021–0115–E that is required for compliance with EASA AD 2021– 0115–E is available on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2021–0345. Justification for Immediate Adoption 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 of a potential quality issue in the fuel pump, including a locking key of the impeller drive shaft that was found loose in the cavity under the impeller. This condition, if combined with a pump operating while not fully immersed in fuel, could create an ignition source in the fuel tank. Operating with a combination of these conditions could result in a fuel tank explosion and consequent loss of the airplane. 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. Comments Invited The FAA invites you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under ADDRESSES. Include ‘‘Docket No. FAA– 2021–0345; Project Identifier MCAI– 2021–00479–T’’ at the beginning of your comments. The most helpful comments reference a specific portion of the final rule, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend this final rule because of those comments. Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to https:// www.regulations.gov, including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this final rule. Confidential Business Information CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this AD contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this AD, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as ‘‘PROPIN.’’ The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this AD. Submissions containing CBI should be sent to Sanjay Ralhan, Aerospace Engineer, Large Aircraft Section, International Validation Branch, FAA, 2200 South 216th St., Des Moines, WA 98198; telephone and fax 206–231–3223; email Sanjay.Ralhan@ faa.gov. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. 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 1,728 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS Labor cost Parts cost Cost per product Cost on U.S. operators 6 work-hours × $85 per hour = $510 .......................................................................................... $* $510 $881,280 jbell on DSKJLSW7X2PROD with RULES * According to the manufacturer, all parts costs of this AD are covered under warranty. The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators. Authority for This Rulemaking Title 49 of the United States Code specifies the FAA’s authority to issue VerDate Sep<11>2014 16:16 Apr 28, 2021 Jkt 253001 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 PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 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 E:\FR\FM\29APR1.SGM 29APR1 22586 Federal Register / Vol. 86, No. 81 / Thursday, April 29, 2021 / Rules and Regulations develop on products identified in this rulemaking action. Regulatory Findings The FAA determined that 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.

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA Emergency AD 2021-0115-E, dated April 
23, 2021 (EASA AD 2021-0115-E) (also referred to as the Mandatory 
Continuing Airworthiness Information, or the MCAI), to correct an 
unsafe condition for all Airbus SAS Model A318, A319, A320, and A321 
series airplanes. Model A320-215 airplanes, which are listed in the 
applicability of EASA AD 2021-0115-E, 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.
    This AD was prompted by the identification of a potential quality 
issue found in the fuel pump that includes a locking key of the 
impeller drive shaft found loose in the cavity under the impeller. 
Incorrect installation of the locking key combined with a pump 
operation not fully immersed in fuel could compromise the fuel pump 
integrity. The FAA is issuing this AD to address this condition, which, 
in the case of operating a pump while not fully immersed in fuel, could 
create an ignition source in the fuel tank, and result in a fuel tank 
explosion and consequent loss of the airplane. See the MCAI for 
additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0115-E specifies procedures for replacement of 
affected fuel pumps. 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 the State of Design Authority, 
the FAA has been notified of the unsafe condition described in the MCAI 
referenced above. The FAA is issuing this AD because the FAA evaluated 
all pertinent information and determined the unsafe condition exists 
and 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 
2021-0115-E described previously, as incorporated by reference, except 
for any differences identified as exceptions in the regulatory text of 
this AD.
    The service information referenced in EASA AD 2021-0115-E includes 
a number of ``RC'' (required for compliance) steps. This AD, however, 
does not require those RC steps, and requires that the replacement be 
done as specified in paragraph (h)(2) of this AD.
    The service information referenced in EASA AD 2021-0115-E specifies 
reporting certain information and sending affected fuel pumps to the 
manufacturer. Those actions are not required by this AD, although the 
FAA recommends that those actions be performed as identified in the 
service information.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA initially worked with Airbus and EASA to develop a 
process to use certain EASA ADs as the primary source of information 
for compliance with requirements for corresponding FAA ADs. The FAA has 
since coordinated with other manufacturers and civil aviation 
authorities (CAAs) to use this process. As a result, EASA AD 2021-0115-
E is incorporated by reference in this final rule. This AD,

[[Page 22585]]

therefore, requires compliance with EASA AD 2021-0115-E 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 the EASA AD 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 the EASA AD. Service information specified in EASA AD

Justification for Immediate Adoption 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 of a potential quality issue in the fuel pump, including a 
locking key of the impeller drive shaft that was found loose in the 
cavity under the impeller. This condition, if combined with a pump 
operating while not fully immersed in fuel, could create an ignition 
source in the fuel tank. Operating with a combination of these 
conditions could result in a fuel tank explosion and consequent loss of 
the airplane. 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.

Comments Invited

    The FAA invites you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
ADDRESSES. Include ``Docket No. FAA-2021-0345; Project Identifier MCAI-
2021-00479-T'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the final rule, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
this final rule because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The agency will also post a report summarizing each 
substantive verbal contact received about this final rule.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this AD contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this AD, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this AD. Submissions containing CBI should be sent to Sanjay 
Ralhan, Aerospace Engineer, Large Aircraft Section, International 
Validation Branch, FAA, 2200 South 216th St., Des Moines, WA 98198; 
telephone and fax 206-231-3223; email [email protected]. Any 
commentary that the FAA receives which is not specifically designated 
as CBI will be placed in the public docket for this rulemaking.

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 1,728 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
6 work-hours x $85 per hour = $510...........................             $ *             $510         $881,280
----------------------------------------------------------------------------------------------------------------
* According to the manufacturer, all parts costs of this AD are covered under warranty.

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some or all of the costs of 
this AD may be covered under warranty, thereby reducing the cost impact 
on affected operators.

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

[[Page 22586]]

develop on products identified in this rulemaking action.

Regulatory Findings

    The FAA determined that 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.

(d) Subject

    Air Transport Association (ATA) of America Code 28, Fuel.

(e) Reason

    This AD was prompted by a potential quality issue in the fuel 
pump that includes a locking key of the impeller drive shaft found 
loose in the cavity under the impeller. The FAA is issuing this AD 
to address this condition, which, if combined with a pump operating 
while not fully immersed in fuel, could create an ignition source in 
the fuel tank, and result in a fuel tank explosion and consequent 
loss of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, European Union Aviation Safety Agency (EASA) 
Emergency AD 2021-0115-E, dated April 23, 2021 (EASA AD 2021-0115-
E).

(h) Exceptions to EASA AD 2021-0115-E
