VerDate Sep<11>2014 16:26 Dec 23, 2021 Jkt 256001 Actions Since AD 2020–26–01 Was Issued Since the FAA issued AD 2020–26– 01, additional parts and additional airplane models have been identified that may also have been subject to an improper overhaul and are therefore unsafe. EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0175, dated July 22, 2021; corrected July 23, 2021 (EASA AD 2021–0175) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition for all Airbus SAS A318–111, A318– 112, A318–121, A318–122, A319–111, A319–112, A319–113, A319–114, A319– 115, A319–131, A319–132, A319–133, A320–211, A320–212, A320–214, A320– 215, A320–216, A320–231, A320–232, A320–233, A321–111, A321–112, A321– 131, A321–211, A321–212, A321–213, A321–231, and A321–232 airplanes. EASA AD 2021–0175 supersedes EASA AD 2020–0258 (which corresponds to FAA AD 2020–26–01). Model A320–215 airplanes are not certificated by the FAA and are not included on the U.S. type certificate data sheet; this proposed AD therefore does not include those airplanes in the applicability. This proposed AD was prompted by reports of cracks found on additional MLG sliding tubes that may have been subject to the same improperly performed magnetic particle inspection as the MLG sliding tubes identified in AD 2020–26–01. The FAA is proposing this AD to address cracks on the MLG sliding tubes, which could cause MLG sliding tube fracture, and could result in the MLG collapsing, damage to the airplane, and injury to occupants. See the MCAI for additional background information. PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 Explanation of Retained Requirements Although this proposed AD does not explicitly restate the requirements of AD 2020–26–01, this proposed AD would retain all of the requirements of AD 2020–26–01. Those requirements are referenced in EASA AD 2021–0175, which, in turn, is referenced in paragraph (g) of this proposed AD. Related Service Information Under 1 CFR Part 51 EASA AD 2021–0175 describes procedures for repetitive general visual inspections of the MLG sliding tubes for cracks, and replacement if necessary. EASA AD 2021–0175 also describes terminating actions for the repetitive inspections of affected MLG sliding tubes by either overhauling an affected MLG sliding tube or replacing an affected MLG sliding tube with an MLG sliding tube that is not affected. 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 and Requirements of This Proposed AD 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 proposing this AD because the FAA evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Proposed AD Requirements This proposed AD would require accomplishing the actions specified in EASA AD 2021–0175 described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD. 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 2021–0175 by reference in the FAA final rule. This E:\FR\FM\27DEP1.SGM 27DEP1 Federal Register / Vol. 86, No. 245 / Monday, December 27, 2021 / Proposed Rules proposed AD would, therefore, require compliance with EASA AD 2021–0175 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 2021–0175 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 2021–0175. Service information required by EASA AD 2021–0175 for compliance will be available at https://www.regulations.gov 73199 by searching for and locating Docket No. FAA–2021–1075 after the FAA final rule is published. Costs of Compliance The FAA estimates that this proposed AD affects 1,524 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Action Labor cost Retained actions from AD 2020–26–01 ......... New proposed actions .................................... 2 work-hours × $85 per hour = $170 ............. 2 work-hours × $85 per hour = $170 ............. The FAA estimates the following costs to do any necessary on-condition actions that would be required based on Cost per product Parts cost the results of any required actions. The FAA has no way of determining the $0 0 $170 170 Cost on U.S. operators $259,080 259,080 number of aircraft that might need these on-condition actions: ESTIMATED COSTS OF ON-CONDITION ACTIONS Labor cost Parts cost Cost per product 19 work-hours × $85 per hour = $1,615 ................................................................................................................. $185 $1,800 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. khammond on DSKJM1Z7X2PROD with PROPOSALS Regulatory Findings 16:26 Dec 23, 2021 Airbus SAS: Docket No. FAA–2021–1075; Project Identifier MCAI–2021–00856–T.

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) 
2020-26-01, which applies to all Airbus SAS Model A318-111, -112, -121, 
and -122 airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, 
and -133 airplanes; and Model A320-211, -212, -214, -216, -231, -232, 
and -233 airplanes. AD 2020-26-01 requires repetitive general visual 
inspections of the affected main landing gear (MLG) sliding tubes for 
cracks and replacement if necessary. Since the FAA issued AD 2020-26-
01, additional parts and additional airplane models have been 
identified that may also have been subject to an improper overhaul and 
are therefore unsafe. This proposed AD would require repetitive general 
visual inspections of the affected MLG sliding tubes (both retained 
affected parts and additional affected parts) for cracks and 
replacement if necessary, as specified in a European Union Aviation 
Safety Agency (EASA) AD, which is proposed for incorporation by 
reference. This proposed AD would also add airplanes to the 
applicability. 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 February 
10, 2022.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION:

Comments Invited

    The FAA invites you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under ADDRESSES. Include ``Docket No. FAA-2021-1075; Project Identifier 
MCAI-2021-00856-T'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the proposal, 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 
the proposal 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 proposed AD.

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 NPRM 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 NPRM, 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 NPRM. 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. Any commentary that the FAA 
receives which is not specifically designated as CBI will be placed in 
the public docket for this rulemaking.

Discussion

    The FAA issued AD 2020-26-01, Amendment 39-21356 (85 FR 82299, 
December 18, 2020) (AD 2020-26-01), which applies to all Airbus SAS 
Model A318-111, -112, -121, and -122 airplanes; Model A319-111, -112, -
113, -114, -115, -131, -132, and -133 airplanes; and Model A320-211, -
212, -214, -216, -231, -232, and -233 airplanes. AD 2020-26-01 requires 
repetitive general visual inspections of the MLG sliding tubes for 
cracks, and replacement if necessary. The FAA issued AD 2020-26-01 to 
address cracks on the MLG sliding tubes, which could cause MLG sliding 
tube fracture, and could result in the MLG collapsing, damage to the 
airplane, and injury to occupants.

Actions Since AD 2020-26-01 Was Issued

    Since the FAA issued AD 2020-26-01, additional parts and additional 
airplane models have been identified that may also have been subject to 
an improper overhaul and are therefore unsafe.
    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0175, dated July 22, 2021; 
corrected July 23, 2021 (EASA AD 2021-0175) (also referred to as the 
Mandatory Continuing Airworthiness Information, or the MCAI), to 
correct an unsafe condition for all Airbus SAS A318-111, A318-112, 
A318-121, A318-122, A319-111, A319-112, A319-113, A319-114, A319-115, 
A319-131, A319-132, A319-133, A320-211, A320-212, A320-214, A320-215, 
A320-216, A320-231, A320-232, A320-233, A321-111, A321-112, A321-131, 
A321-211, A321-212, A321-213, A321-231, and A321-232 airplanes. EASA AD 
2021-0175 supersedes EASA AD 2020-0258 (which corresponds to FAA AD 
2020-26-01). Model A320-215 airplanes are not certificated by the FAA 
and are not included on the U.S. type certificate data sheet; this 
proposed AD therefore does not include those airplanes in the 
applicability.
    This proposed AD was prompted by reports of cracks found on 
additional MLG sliding tubes that may have been subject to the same 
improperly performed magnetic particle inspection as the MLG sliding 
tubes identified in AD 2020-26-01. The FAA is proposing this AD to 
address cracks on the MLG sliding tubes, which could cause MLG sliding 
tube fracture, and could result in the MLG collapsing, damage to the 
airplane, and injury to occupants. See the MCAI for additional 
background information.

Explanation of Retained Requirements

    Although this proposed AD does not explicitly restate the 
requirements of AD 2020-26-01, this proposed AD would retain all of the 
requirements of AD 2020-26-01. Those requirements are referenced in 
EASA AD 2021-0175, which, in turn, is referenced in paragraph (g) of 
this proposed AD.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0175 describes procedures for repetitive general 
visual inspections of the MLG sliding tubes for cracks, and replacement 
if necessary. EASA AD 2021-0175 also describes terminating actions for 
the repetitive inspections of affected MLG sliding tubes by either 
overhauling an affected MLG sliding tube or replacing an affected MLG 
sliding tube with an MLG sliding tube that is not affected.
    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 and Requirements of This Proposed AD

    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 proposing this AD because the FAA 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2021-0175 described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this AD.

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 2021-0175 by reference in the FAA 
final rule. This

[[Page 73199]]

proposed AD would, therefore, require compliance with EASA AD 2021-0175 
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 2021-0175 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 2021-0175. Service information 
required by EASA AD 2021-0175 for compliance will be available at 
https://www.regulations.gov by searching for and locating Docket No. 
FAA-2021-1075 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this proposed AD affects 1,524 airplanes of 
U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

                                      Estimated Costs for Required Actions

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

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required actions. The FAA has no way of determining the number of 
aircraft that might need these on-condition actions:

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) 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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

(j) Other 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 (k)(2) of 
this AD. Information may be emailed to: [email protected]. 
Before using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
responsible Flight Standards Office.
    (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, Large Aircraft 
Section, International Validation Branch, FAA; or EASA; or Airbus
