The FAA amends § 39.13 by adding the following new airworthiness directive: ■ Airbus SAS: Docket No. FAA–2021–1059; Project Identifier MCAI–2021–00797–T. (a) Comments Due Date The FAA must receive comments on this airworthiness directive (AD) by January 31, 2022. (b) Affected ADs None. (c) Applicability This AD applies to all Airbus SAS Model A350–941 and –1041 airplanes, certificated in any category. (d) Subject Air Transport Association (ATA) of America Code 32, Landing gear. (e) Unsafe Condition This AD was prompted by a report that in the event of a specific discrete wire failure, the landing gear extension and retraction system (LGERS) may not be able to complete landing gear retraction when commanded by moving the landing gear lever to the UP position. The FAA is issuing this AD to address this condition, which, if one engine is inoperative at takeoff, could lead to a reduction of the flight path clearance and possibly result in damage to the airplane and injury to occupants. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (j) Related Information (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, EASA AD 2021–0161, dated July 6, 2021 (EASA AD 2021–0161). jspears on DSK121TN23PROD with PROPOSALS1 (h) Exceptions to EASA AD 2021–0161 (1) Where EASA AD 2021–0161 refers to its effective date, this AD requires using the effective date of this AD. (2) Whereas paragraph (1) of EASA AD 2021–0161 specifies to ‘‘inform all flight crews, and, thereafter, operate the aeroplane accordingly,’’ this AD does not require those actions as those actions are already required by existing FAA operating regulations. (3) The ‘‘Remarks’’ section of EASA AD 2021–0161 does not apply to this AD. (i) Additional 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.

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 Antariksh Shetty, Aerospace Engineer, Airframe and Propulsion Section, FAA, New York ACO Branch, 1600 Stewart Avenue, Suite 410, Westbury, NY 11590; telephone 516–228–7300; email 9-avsnyaco-cos@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. Background The TCCA, which is the aviation authority for Canada, has issued TCCA AD CF–2021–25, dated July 22, 2021 (TCCA AD CF–2021–25) (also referred to as the MCAI), to correct an unsafe condition for certain Airbus Canada Limited Partnership Model BD–500– 1A10 and BD–500–1A11 airplanes. This proposed AD was prompted by a report that some tie-rod assemblies may have been over-tightened during the installation of interior monuments (such as galleys, lavatories, and forward stowage or wardrobes). The FAA is proposing this AD to address overtightened (pre-loaded) tie-rods that induce unwanted stress in a monument and may cause the monument to become unconstrained in an emergency landing, potentially blocking exits or injuring occupants. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 TCCA AD CF–2021–25 specifies procedures for, among other actions, adjustment of the affected tie-rod assemblies to remove any pre-load. 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 PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 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 these same type designs. Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in TCCA AD CF–2021–25 described previously, except for any differences identified as exceptions in the regulatory text of this proposed AD and except as discussed under ‘‘Difference Between this Proposed AD and the MCAI.’’ 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 TCCA AD CF–2021–25 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with TCCA AD CF–2021–25 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Service information required by TCCA AD CF–2021–25 for compliance will be available at https://www.regulations.gov by searching for and locating Docket No. FAA–2021–1067 after the FAA final rule is published. Difference Between This Proposed AD and the MCAI TCCA AD CF–2021–25 specifies an inspection of the tie-rod for pre-load. The service information required by TCCA AD CF–2021–25 specifies that it ‘‘gives the procedure to inspect and release the load the tie-rod assemblies,’’ but does not include any specific inspection procedures. This proposed AD does not propose to include any inspection. Costs of Compliance The FAA estimates that this proposed AD would affect 21 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: E:\FR\FM\17DEP1.SGM 17DEP1 Federal Register / Vol. 86, No. 240 / Friday, December 17, 2021 / Proposed Rules 71591 ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost 5 work-hours × $85 per hour = $425 .......................................................................................... None .............. 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. 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. jspears on DSK121TN23PROD with PROPOSALS1 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: VerDate Sep<11>2014 17:38 Dec 16, 2021 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. [Amended] 2.

Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0181, dated July 30, 2021 (EASA AD 2021– 0181) (also referred to as the MCAI), to correct an unsafe condition for all Airbus SAS Model A300 B2–1C, B2K– 3C, B2–203, B4–2C, B4–103, and B4– 203 airplanes. EASA AD 2021–0181 specifies that it requires certain tasks (limitations) already required by EASA AD 2017– 0207, dated October 12, 2017 (which corresponds to FAA AD 2018–19–17, Amendment 39–19417 (83 FR 48207, September 24, 2018) (AD 2018–19–17)), and invalidates prior instructions for those tasks. This proposed AD would, for AD 2018–19–17, terminate the limitation for the tasks identified in the service information referred to in EASA AD 2021–0181 only. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations for pylon maintenance are necessary. The FAA is proposing this AD to address fatigue cracking, damage, and corrosion in principal structural elements; such fatigue cracking, damage, and corrosion could result in reduced structural integrity of the airplane.

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-
500-1A11 airplanes. This proposed AD was prompted by a report that some 
tie-rod assemblies may have been over-tightened during the installation 
of interior monuments (such as galleys, lavatories, and forward stowage 
or wardrobes). This proposed AD would require adjusting the tie-rod 
assemblies, as specified in a Transport Canada Civil Aviation (TCCA) 
AD, which is proposed for incorporation by reference. The FAA is 
proposing this AD to address the unsafe condition on these products.

Background

    The TCCA, which is the aviation authority for Canada, has issued 
TCCA AD CF-2021-25, dated July 22, 2021 (TCCA AD CF-2021-25) (also 
referred to as the MCAI), to correct an unsafe condition for certain 
Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 
airplanes.
    This proposed AD was prompted by a report that some tie-rod 
assemblies may have been over-tightened during the installation of 
interior monuments (such as galleys, lavatories, and forward stowage or 
wardrobes). The FAA is proposing this AD to address over-tightened 
(pre-loaded) tie-rods that induce unwanted stress in a monument and may 
cause the monument to become unconstrained in an emergency landing, 
potentially blocking exits or injuring occupants. See the MCAI for 
additional background information.

Related Service Information Under 1 CFR Part 51

    TCCA AD CF-2021-25 specifies procedures for, among other actions, 
adjustment of the affected tie-rod assemblies to remove any pre-load. 
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 these same type designs.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in TCCA AD CF-2021-25 described previously, except for any differences 
identified as exceptions in the regulatory text of this proposed AD and 
except as discussed under ``Difference Between this Proposed AD and the 
MCAI.''

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 TCCA AD CF-2021-25 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
TCCA AD CF-2021-25 in its entirety through that incorporation, except 
for any differences identified as exceptions in the regulatory text of 
this proposed AD. Service information required by TCCA AD CF-2021-25 
for compliance will be available at https://www.regulations.gov by 
searching for and locating Docket No. FAA-2021-1067 after the FAA final 
rule is published.

Difference Between This Proposed AD and the MCAI

    TCCA AD CF-2021-25 specifies an inspection of the tie-rod for pre-
load. The service information required by TCCA AD CF-2021-25 specifies 
that it ``gives the procedure to inspect and release the load the tie-
rod assemblies,'' but does not include any specific inspection 
procedures. This proposed AD does not propose to include any 
inspection.

Costs of Compliance

    The FAA estimates that this proposed AD would affect 21 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.
