Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Airbus SAS Model A350-941 airplanes. This proposed AD was 
prompted by a report indicating that the inflatable free aisle 
restrictor (IFAR) on certain single lane slide-rafts demonstrated 
inconsistent release behavior in aft wind conditions. This proposed AD 
would require replacing an affected part with a serviceable part, 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 August 1, 
2022.

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

    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 NPRM.

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

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

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2022-0013, dated January 25, 2022 
(EASA AD 2022-0013) (also referred to as the MCAI), to correct an 
unsafe condition for all Airbus SAS Model A350-941 airplanes.
    This proposed AD was prompted by a report indicating that following 
the introduction of the IFAR system on single lane slide-rafts, the 
IFAR demonstrated inconsistent release behavior due to interference or 
entanglement of the upper part of the IFAR with the slide-raft cover or 
door structure in aft wind conditions. These affected slide-rafts are 
installed at passenger door 3, left-hand and right-hand sides. The FAA 
is proposing this AD to address inconsistent release of single lane 
slide-rafts having the IFAR system, which if not corrected, could 
result in a slide-raft being unusable during an emergency and impair 
the safe evacuation of occupants. See the MCAI for additional 
background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2022-0013 specifies procedures for replacing escape slide-
rafts having certain part numbers (affected parts) with serviceable 
parts (which includes parts that have been modified and re-identified). 
EASA AD 2022-0013 also prohibits the installation of affected parts on 
any airplane.
    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

    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, 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 design.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2022-0013 described previously, except for any differences 
identified as exceptions in the regulatory text of this proposed AD. 
This proposed AD would also prohibit the installation of affected 
parts.

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 2022-0013 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2022-0013 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 2022-0013 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-
0013. Service information required by EASA AD 2022-0013 for compliance 
will be available at https://www.regulations.gov by searching for and 
locating Docket No. FAA-2022-0686 after the FAA final rule is 
published.

Costs of Compliance

    The FAA estimates that this proposed AD would affect 30 airplanes 
of U.S. registry. The FAA estimates the following costs to comply with 
this proposed AD:

[[Page 36420]]



                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
             Labor cost                Parts cost           Cost per product           Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 11 work-hours x $85 per hour             $400  Up to $1,335.................  Up to $40,050.
 = Up to $935.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this 
proposed AD maybe covered under warranty, thereby reducing the cost 
impact on affected operators. The FAA does not control warranty 
coverage for affected operators. As a result, the FAA has included all 
known costs in the cost estimate.

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.
