DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2022–1060; Project Identifier MCAI–2022–00251–T] RIN 2120–AA64 Airworthiness Directives; Airbus SAS Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to supersede Airworthiness Directive (AD) 2021–14–08, which applies to all Airbus SAS Model A319–151N, A319–153N, A319–171N, A320–251N, A320–252N, A320–273N, A321–251N, A321–251NX, A321–252N, A321–252NX, A321–253N, A321–253NX, A321–271N, A321– 271NX, A321–272N, and A321–272NX airplanes. AD 2021–14–08 requires revising the existing airplane flight manual (AFM) to include a procedure to reinforce the airspeed check during the take-off phase and provide instructions to abort take-off in certain cases. This AD was prompted by the development of a software update to the elevator aileron computer (ELAC) to address the unsafe condition. This proposed AD would continue to require the actions in AD 2021–14–08 and would require replacing each affected ELAC and removing the AFM revision required by AD 2021–14–08, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. This proposed AD would also prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products. DATES: The FAA must receive comments on this proposed AD by October 7, 2022. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: lotter on DSK11XQN23PROD with PROPOSALS1 SUMMARY: VerDate Sep<11>2014 18:03 Aug 22, 2022 Jkt 256001 • Federal eRulemaking Portal: Go to regulations.gov.

Background The FAA issued AD 2021–14–08, Amendment 39–21635 (86 FR 34933, July 1, 2021) (AD 2021–14–08), for all Airbus SAS Model A319–151N, A319– 153N, A319–171N, A320–251N, A320– 252N, A320–253N, A320–271N, A320– 272N, A320–273N, A321–251N, A321– 251NX, A321–252N, A321–252NX, A321–253N, A321–253NX, A321–271N, A321–271NX, A321–272N, and A321– E:\FR\FM\23AUP1.SGM 23AUP1 51618 Federal Register / Vol. 87, No. 162 / Tuesday, August 23, 2022 / Proposed Rules 272NX airplanes. AD 2021–14–08 requires revising the existing AFM to include a procedure to reinforce the airspeed check during the take-off phase and provide instructions to abort takeoff in certain cases. The FAA issued AD 2021–14–08 to address airspeed discrepancies, which could lead to an unstable flight path after take-off, possibly resulting in reduced control of the airplane. Actions Since AD 2021–14–08 Was Issued The preamble to AD 2021–14–08 explains that the FAA considers that AD to be interim action and that further action might follow. Since the FAA issued AD 2021–14–08, the manufacturer developed a software update to the ELAC to address the unsafe condition, and the FAA has determined that further rulemaking is necessary. Installation of this software update would eliminate the need for the AFM revision required by AD 2021–14– 08. EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2022–0028, dated February 22, 2022 (EASA AD 2022–0028) (also referred to as the MCAI), to correct an unsafe condition for all Airbus SAS Model A319–151N, –153N, and –171N airplanes; Model A320–251N, –252N, –253N, –271N, –272N, and –273N airplanes; and Model A321–251N, –251NX, –252N, –252NX, –253N, –253NX, –271N, –271NX, –272N, and –272NX airplanes. This proposed AD was prompted by the development of a software update to the ELAC to address the unsafe condition. The FAA is proposing this AD to address airspeed discrepancies, which could lead to an unstable flight path after take-off, possibly resulting in reduced control of the airplane. See the MCAI for additional background information. lotter on DSK11XQN23PROD with PROPOSALS1 Explanation of Retained Requirements Although this proposed AD does not explicitly restate the requirements of AD 2021–14–08, this proposed AD would retain all of the requirements of AD 2021–14–08. Those requirements are referenced in EASA AD 2022–0028, which, in turn, is referenced in paragraph (g) of this proposed AD. Related Service Information Under 1 CFR Part 51 EASA AD 2022–0028 specifies procedures for, among other actions, revising the AFM to include a procedure to reinforce the airspeed check during VerDate Sep<11>2014 18:03 Aug 22, 2022 Jkt 256001 the take-off phase and provide instructions to abort take-off in certain cases (e.g., and unreliable airspeed situation or certain airspeed differences); replacing each affected ELAC with a serviceable ELAC (one with the updated ELAC software standard); and removing the AFM revision required by AD 2021–14–08. EASA AD 2022–0028 also prohibits installation of affected ELACs. 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 These products have been approved by the aviation authority of another country and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with the State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA is issuing this NPRM after determining that the unsafe condition described previously is likely to exist or develop in other products of the same type designs. Proposed AD Requirements in This NPRM This proposed AD would retain all requirements of AD 2021–14–08. This proposed AD would require accomplishing the actions specified in EASA AD 2022–0028 described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD, and except as discussed under ‘‘Differences Between this AD and the MCAI.’’ Differences Between This AD and the MCAI Paragraph (3) of EASA AD 2022–0028 requires revising the minimum equipment list (MEL) to incorporate an EASA master minimum equipment list (MMEL) change to mandate that the integrated standby instrument system (ISIS) airspeed indication must be operative. However the FAA MMEL does not provide relief for an inoperative ISIS airspeed indication function. Therefore, paragraph (3) of EASA AD 2022–0028 is unnecessary for this AD. EASA AD 2022–0028 requires operators to ‘‘inform all flight crews’’ of revisions to the AFM, and thereafter to ‘‘operate the aeroplane accordingly.’’ However, this proposed AD would not specifically require those actions as those actions are already required by PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 FAA regulations. FAA regulations require operators furnish to pilots any changes to the AFM (for example, 14 CFR 121.137), and to ensure the pilots are familiar with the AFM (for example, 14 CFR 91.505). As with any other flightcrew training requirement, training on the updated AFM content is tracked by the operators and recorded in each pilot’s training record, which is available for the FAA to review. FAA regulations also require pilots to follow the procedures in the existing AFM including all updates. 14 CFR 91.9 requires that any person operating a civil aircraft must comply with the operating limitations specified in the AFM. Therefore, including a requirement in this proposed AD to operate the airplane according to the revised AFM would be redundant and unnecessary. 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, the FAA proposes to incorporate EASA AD 2022–0028 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2022–0028 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in EASA AD 2022–0028 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 2022–0028. Service information required by EASA AD 2022–0028 for compliance will be available at regulations.gov by searching for and locating Docket No. FAA–2022– 1060 after the FAA final rule is published. Costs of Compliance The FAA estimates that this proposed AD affects 204 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: E:\FR\FM\23AUP1.SGM 23AUP1 Federal Register / Vol. 87, No. 162 / Tuesday, August 23, 2022 / Proposed Rules 51619 ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost Retained actions from AD 2021–14–08 ......... New proposed actions .................................... 1 work-hour × $85 per hour = $85 ................. 3 work-hours × $85 per hour = $355 ............. 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 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. lotter on DSK11XQN23PROD with PROPOSALS1 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2021-14-08, which applies to all Airbus SAS Model A319-151N, A319-153N, 
A319-171N, A320-251N, A320-252N, A320-273N, A321-251N, A321-251NX, 
A321-252N, A321-252NX, A321-253N, A321-253NX, A321-271N, A321-271NX, 
A321-272N, and A321-272NX airplanes. AD 2021-14-08 requires revising 
the existing airplane flight manual (AFM) to include a procedure to 
reinforce the airspeed check during the take-off phase and provide 
instructions to abort take-off in certain cases. This AD was prompted 
by the development of a software update to the elevator aileron 
computer (ELAC) to address the unsafe condition. This proposed AD would 
continue to require the actions in AD 2021-14-08 and would require 
replacing each affected ELAC and removing the AFM revision required by 
AD 2021-14-08, as specified in a European Union Aviation Safety Agency 
(EASA) AD, which is proposed for incorporation by reference. This 
proposed AD would also prohibit the installation of affected parts. The 
FAA is proposing this AD to address the unsafe condition on these 
products.

Background

    The FAA issued AD 2021-14-08, Amendment 39-21635 (86 FR 34933, July 
1, 2021) (AD 2021-14-08), for all Airbus SAS Model A319-151N, A319-
153N, A319-171N, A320-251N, A320-252N, A320-253N, A320-271N, A320-272N, 
A320-273N, A321-251N, A321-251NX, A321-252N, A321-252NX, A321-253N, 
A321-253NX, A321-271N, A321-271NX, A321-272N, and A321-

[[Page 51618]]

272NX airplanes. AD 2021-14-08 requires revising the existing AFM to 
include a procedure to reinforce the airspeed check during the take-off 
phase and provide instructions to abort take-off in certain cases. The 
FAA issued AD 2021-14-08 to address airspeed discrepancies, which could 
lead to an unstable flight path after take-off, possibly resulting in 
reduced control of the airplane.

Actions Since AD 2021-14-08 Was Issued

    The preamble to AD 2021-14-08 explains that the FAA considers that 
AD to be interim action and that further action might follow. Since the 
FAA issued AD 2021-14-08, the manufacturer developed a software update 
to the ELAC to address the unsafe condition, and the FAA has determined 
that further rulemaking is necessary. Installation of this software 
update would eliminate the need for the AFM revision required by AD 
2021-14-08.
    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2022-0028, dated February 22, 2022 
(EASA AD 2022-0028) (also referred to as the MCAI), to correct an 
unsafe condition for all Airbus SAS Model A319-151N, -153N, and -171N 
airplanes; Model A320-251N, -252N, -253N, -271N, -272N, and -273N 
airplanes; and Model A321-251N, -251NX, -252N, -252NX, -253N, -253NX, -
271N, -271NX, -272N, and -272NX airplanes.
    This proposed AD was prompted by the development of a software 
update to the ELAC to address the unsafe condition. The FAA is 
proposing this AD to address airspeed discrepancies, which could lead 
to an unstable flight path after take-off, possibly resulting in 
reduced control of the airplane. See the MCAI for additional background 
information.

Explanation of Retained Requirements

    Although this proposed AD does not explicitly restate the 
requirements of AD 2021-14-08, this proposed AD would retain all of the 
requirements of AD 2021-14-08. Those requirements are referenced in 
EASA AD 2022-0028, which, in turn, is referenced in paragraph (g) of 
this proposed AD.

Related Service Information Under 1 CFR Part 51

    EASA AD 2022-0028 specifies procedures for, among other actions, 
revising the AFM to include a procedure to reinforce the airspeed check 
during the take-off phase and provide instructions to abort take-off in 
certain cases (e.g., and unreliable airspeed situation or certain 
airspeed differences); replacing each affected ELAC with a serviceable 
ELAC (one with the updated ELAC software standard); and removing the 
AFM revision required by AD 2021-14-08. EASA AD 2022-0028 also 
prohibits installation of affected ELACs. 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

    These products have been approved by the aviation authority of 
another country and are approved for operation in the United States. 
Pursuant to the FAA's bilateral agreement with the State of Design 
Authority, it has notified the FAA of the unsafe condition described in 
the MCAI referenced above. The FAA is issuing this NPRM after 
determining that the unsafe condition described previously is likely to 
exist or develop in other products of the same type designs.

Proposed AD Requirements in This NPRM

    This proposed AD would retain all requirements of AD 2021-14-08. 
This proposed AD would require accomplishing the actions specified in 
EASA AD 2022-0028 described previously, except for any differences 
identified as exceptions in the regulatory text of this proposed AD, 
and except as discussed under ``Differences Between this AD and the 
MCAI.''

Differences Between This AD and the MCAI

    Paragraph (3) of EASA AD 2022-0028 requires revising the minimum 
equipment list (MEL) to incorporate an EASA master minimum equipment 
list (MMEL) change to mandate that the integrated standby instrument 
system (ISIS) airspeed indication must be operative. However the FAA 
MMEL does not provide relief for an inoperative ISIS airspeed 
indication function. Therefore, paragraph (3) of EASA AD 2022-0028 is 
unnecessary for this AD.
    EASA AD 2022-0028 requires operators to ``inform all flight crews'' 
of revisions to the AFM, and thereafter to ``operate the aeroplane 
accordingly.'' However, this proposed AD would not specifically require 
those actions as those actions are already required by FAA regulations. 
FAA regulations require operators furnish to pilots any changes to the 
AFM (for example, 14 CFR 121.137), and to ensure the pilots are 
familiar with the AFM (for example, 14 CFR 91.505). As with any other 
flightcrew training requirement, training on the updated AFM content is 
tracked by the operators and recorded in each pilot's training record, 
which is available for the FAA to review. FAA regulations also require 
pilots to follow the procedures in the existing AFM including all 
updates. 14 CFR 91.9 requires that any person operating a civil 
aircraft must comply with the operating limitations specified in the 
AFM. Therefore, including a requirement in this proposed AD to operate 
the airplane according to the revised AFM would be redundant and 
unnecessary.

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, the 
FAA proposes to incorporate EASA AD 2022-0028 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2022-0028 in its entirety through that incorporation, except 
for any differences identified as exceptions in the regulatory text of 
this proposed AD. Using common terms that are the same as the heading 
of a particular section in EASA AD 2022-0028 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 2022-
0028. Service information required by EASA AD 2022-0028 for compliance 
will be available at regulations.gov by searching for and locating 
Docket No. FAA-2022-1060 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 204 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

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

    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.

(i) Additional FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
Large Aircraft Section, International Validation Branch, FAA, has 
the authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or responsible Flight 
Standards Office, as appropriate. If sending information directly to 
the Large Aircraft Section, International Validation Branch, send it 
to the attention of the person identified in paragraph (j)(2) of 
this AD. Information may be emailed to: [email protected].
    (i) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the responsible Flight Standards Office.
    (ii) AMOCs approved previously for AD 2022-14-08 are approved as 
AMOCs for the corresponding provisions of EASA AD 2022-0028 that are 
required by paragraph (g) of this AD.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain instructions from a manufacturer, the instructions must be
