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 FAA issued AD 2022–09–03, Amendment 39–22023 (87 FR 29030, May 12, 2022) (AD 2022–09–03), which applies to certain Airbus SAS Model A350–941 and –1041 airplanes. AD 2022–09–03 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA issued AD 2022– 09–03 to address the potential failure of certain life-limited parts, which could result in reduced structural integrity of the airplane. Actions Since AD 2022–09–03 Was Issued Since the FAA issued AD 2022–09– 03, the FAA has determined that additional new or more restrictive airworthiness limitations are necessary. EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2022–0124, dated June 28, 2022 (EASA AD 2022– 0124) (also referred to as the MCAI), to correct an unsafe condition for all Airbus SAS Model A350–941 and –1041 airplanes. EASA AD 2022–0124 superseded EASA AD 2021–0206 (which corresponds to FAA AD 2022– 09–03). Airplanes with an original airworthiness certificate or original export certificate of airworthiness issued after May 2, 2022 must comply with the airworthiness limitations specified as part of the approved type design and referenced on the type PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 certificate data sheet; this proposed AD therefore does not include those airplanes in the applicability. This proposed AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is proposing this AD to address the potential failure of certain life-limited parts, which could result in reduced structural integrity of the airplane. See the MCAI for additional background information. Related Service Information Under 1 CFR Part 51 EASA AD 2022–0124 specifies new or more restrictive airworthiness limitations for airplane structures and safe life limits. This proposed AD would also require EASA AD 2021–0206, dated September 15, 2021, which the Director of the Federal Register approved for incorporation by reference as of June 16, 2022 (87 FR 29030, May 12, 2022). 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 described 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 retain the requirements of AD 2022–09–03. This proposed AD would also require revising the existing maintenance or inspection program, as applicable, to incorporate additional new or more restrictive airworthiness limitations, which are specified in EASA AD 2022– 0124 described previously, as proposed for incorporation by reference. Any differences with EASA AD 2022–0124 are identified as exceptions in the regulatory text of this AD. This proposed AD would require revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed E:\FR\FM\09NOP1.SGM 09NOP1 Federal Register / Vol. 87, No. 216 / Wednesday, November 9, 2022 / Proposed Rules AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance (AMOC) according to paragraph (m)(1) of this proposed AD. khammond on DSKJM1Z7X2PROD with PROPOSALS 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 2022–0124 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2022–0124 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 2022–0124 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 2022–0124. Service information required by EASA AD 2022–0124 for compliance will be available at regulations.gov under Docket No. FAA–2022–1408 after the FAA final rule is published. Airworthiness Limitation ADs Using the New Process The FAA’s process of incorporating by reference MCAI ADs as the primary source of information for compliance with corresponding FAA ADs has been limited to certain MCAI ADs (primarily those with service bulletins as the primary source of information for accomplishing the actions required by the FAA AD). However, the FAA is now expanding the process to include MCAI ADs that require a change to airworthiness limitation documents, such as airworthiness limitation sections. For these ADs that incorporate by reference an MCAI AD that changes airworthiness limitations, the FAA requirements are unchanged. Operators must revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in the new airworthiness limitation VerDate Sep<11>2014 17:55 Nov 08, 2022 Jkt 259001 document. The airworthiness limitations must be followed according to 14 CFR 91.403(c) and 91.409(e). The previous format of the airworthiness limitation ADs included a paragraph that specified that no alternative actions (e.g., inspections) may be used unless the actions and intervals are approved as an AMOC in accordance with the procedures specified in the AMOCs paragraph under ‘‘Additional AD Provisions.’’ This new format includes a ‘‘New Provisions for Alternative Actions and Intervals’’ paragraph that does not specifically refer to AMOCs, but operators may still request an AMOC to use an alternative action or interval. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 30 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: The FAA estimates the total cost per operator for the retained actions from AD 2022–09–03 to be $7,650 (90 workhours × $85 per work-hour). The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 workhours per operator, although the agency recognizes that this number may vary from operator to operator. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. The FAA estimates the total cost per operator for the new proposed actions to be $7,650 (90 work-hours × $85 per work-hour). 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 PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 67577 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. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

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) 
2022-09-03, which applies to certain Airbus SAS Model A350-941 and -
1041 airplanes. AD 2022-09-03 requires revising the existing 
maintenance or inspection program, as applicable, to incorporate new or 
more restrictive airworthiness limitations. Since the FAA issued AD 
2022-09-03, the FAA has determined that new or more restrictive 
airworthiness limitations are necessary. This proposed AD would 
continue to require the actions in AD 2022-09-03 and require revising 
the existing maintenance or inspection program, as applicable, to 
incorporate additional new or more restrictive airworthiness 
limitations, as specified in a European Union Aviation Safety Agency 
(EASA) AD, which is proposed for incorporation by reference (IBR). 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 December 
27, 2022.

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 Dan 
Rodina, Aerospace Engineer, Large Aircraft Section, FAA, International 
Validation Branch, 2200 South 216th St., Des Moines, WA 98198;

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

Background

    The FAA issued AD 2022-09-03, Amendment 39-22023 (87 FR 29030, May 
12, 2022) (AD 2022-09-03), which applies to certain Airbus SAS Model 
A350-941 and -1041 airplanes. AD 2022-09-03 requires revising the 
existing maintenance or inspection program, as applicable, to 
incorporate new or more restrictive airworthiness limitations. The FAA 
issued AD 2022-09-03 to address the potential failure of certain life-
limited parts, which could result in reduced structural integrity of 
the airplane.

Actions Since AD 2022-09-03 Was Issued

    Since the FAA issued AD 2022-09-03, the FAA has determined that 
additional new or more restrictive airworthiness limitations are 
necessary.
    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2022-0124, dated June 28, 2022 (EASA 
AD 2022-0124) (also referred to as the MCAI), to correct an unsafe 
condition for all Airbus SAS Model A350-941 and -1041 airplanes. EASA 
AD 2022-0124 superseded EASA AD 2021-0206 (which corresponds to FAA AD 
2022-09-03).
    Airplanes with an original airworthiness certificate or original 
export certificate of airworthiness issued after May 2, 2022 must 
comply with the airworthiness limitations specified as part of the 
approved type design and referenced on the type certificate data sheet; 
this proposed AD therefore does not include those airplanes in the 
applicability.
    This proposed AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. The FAA is 
proposing this AD to address the potential failure of certain life-
limited parts, which could result in reduced structural integrity of 
the airplane. See the MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2022-0124 specifies new or more restrictive airworthiness 
limitations for airplane structures and safe life limits.
    This proposed AD would also require EASA AD 2021-0206, dated 
September 15, 2021, which the Director of the Federal Register approved 
for incorporation by reference as of June 16, 2022 (87 FR 29030, May 
12, 2022).
    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 described 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 retain the requirements of AD 2022-09-03. 
This proposed AD would also require revising the existing maintenance 
or inspection program, as applicable, to incorporate additional new or 
more restrictive airworthiness limitations, which are specified in EASA 
AD 2022-0124 described previously, as proposed for incorporation by 
reference. Any differences with EASA AD 2022-0124 are identified as 
exceptions in the regulatory text of this AD.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections). 
Compliance with these actions is required by 14 CFR 91.403(c). For 
airplanes that have been previously modified, altered, or repaired in 
the areas addressed by this proposed

[[Page 67577]]

AD, the operator may not be able to accomplish the actions described in 
the revisions. In this situation, to comply with 14 CFR 91.403(c), the 
operator must request approval for an alternative method of compliance 
(AMOC) according to paragraph (m)(1) of this proposed 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 2022-0124 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2022-0124 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 2022-0124 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-
0124. Service information required by EASA AD 2022-0124 for compliance 
will be available at regulations.gov under Docket No. FAA-2022-1408 
after the FAA final rule is published.

Airworthiness Limitation ADs Using the New Process

    The FAA's process of incorporating by reference MCAI ADs as the 
primary source of information for compliance with corresponding FAA ADs 
has been limited to certain MCAI ADs (primarily those with service 
bulletins as the primary source of information for accomplishing the 
actions required by the FAA AD). However, the FAA is now expanding the 
process to include MCAI ADs that require a change to airworthiness 
limitation documents, such as airworthiness limitation sections.
    For these ADs that incorporate by reference an MCAI AD that changes 
airworthiness limitations, the FAA requirements are unchanged. 
Operators must revise the existing maintenance or inspection program, 
as applicable, to incorporate the information specified in the new 
airworthiness limitation document. The airworthiness limitations must 
be followed according to 14 CFR 91.403(c) and 91.409(e).
    The previous format of the airworthiness limitation ADs included a 
paragraph that specified that no alternative actions (e.g., 
inspections) may be used unless the actions and intervals are approved 
as an AMOC in accordance with the procedures specified in the AMOCs 
paragraph under ``Additional AD Provisions.'' This new format includes 
a ``New Provisions for Alternative Actions and Intervals'' paragraph 
that does not specifically refer to AMOCs, but operators may still 
request an AMOC to use an alternative action or interval.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 30 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:
    The FAA estimates the total cost per operator for the retained 
actions from AD 2022-09-03 to be $7,650 (90 work-hours x $85 per work-
hour).
    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the agency recognizes that this number may vary from operator 
to operator. Since operators incorporate maintenance or inspection 
program changes for their affected fleet(s), the FAA has determined 
that a per-operator estimate is more accurate than a per-airplane 
estimate.
    The FAA estimates the total cost per operator for the new proposed 
actions to be $7,650 (90 work-hours x $85 per work-hour).

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.
