Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2020-09-
14, which applied to certain Airbus SAS Model A350-941 and -1041 
airplanes. AD 2020-09-14 required revising the existing airplane flight 
manual (AFM) to define a liquid-prohibited zone on the flight deck and 
provide procedures following liquid spillage on the center pedestal. AD 
2020-09-14 also required installing a removable integrated control 
panel (ICP) cover on the flight deck and further revising the AFM to 
include instructions for ICP cover use. This AD requires installing a 
new, water-resistant ICP, which allows removing the ICP protective 
cover and the AFM revisions, as specified in a European Union Aviation 
Safety Agency (EASA) AD, which is incorporated by reference. This AD 
was prompted by development of a new, water-resistant ICP. The FAA is 
issuing this AD to address the unsafe condition on these products.

DATES: This AD is effective July 29, 2021.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of July 29, 
2021.

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0203, dated September 23, 2020 
(EASA AD 2020-0203) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
for certain Airbus SAS Model A350-941 and -1041 airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2020-09-14, Amendment 39-19910 (85 FR 
30601, May 20, 2020) (AD 2020-09-14). AD 2020-09-14 applied to certain 
Airbus SAS Model A350-941 and -1041 airplanes. The NPRM published in 
the

[[Page 33095]]

Federal Register on February 22, 2021 (86 FR 10493). The NPRM was 
prompted by a new, water-resistant ICP developed by the manufacturer to 
address the identified unsafe condition. The NPRM proposed to continue 
to require revising the existing AFM to define a liquid-prohibited zone 
on the flight deck and provide procedures following liquid spillage on 
the center pedestal. The NPRM also proposed to continue to require 
installing a removable ICP cover on the flight deck and further 
revising the AFM to include instructions for ICP cover use, as 
specified in EASA AD 2020-0203. The NPRM also proposed to require 
installing a new, water-resistant ICP, which would allow removing the 
ICP protective cover and the AFM revisions, as specified in EASA AD 
2020-0203.
    The FAA is issuing this AD to address the potential for dual-engine 
in-flight shutdown (IFSD), possibly resulting in a forced landing with 
consequent damage to the airplane and injury to occupants. See the MCAI 
for additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA has considered the comment 
received. The Air Line Pilots Association, International (ALPA) 
indicated its support for the NPRM.

Change to the Costs of Compliance Section

    In the NPRM, the FAA did not provide a parts cost estimate for the 
new actions, and it was noted that the FAA had received no definitive 
data regarding cost estimates for those parts. Since publication of the 
NPRM, the FAA has obtained a parts cost estimate from the manufacturer, 
and has updated the Costs of Compliance section of this final rule 
accordingly.

Conclusion

    The FAA reviewed the relevant data, considered the comment 
received, and determined that air safety and the public interest 
require adopting this final rule as proposed, except for minor 
editorial changes. The FAA has determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    EASA AD 2020-0203 describes procedures for revising the AFM to 
define a liquid-prohibited zone on the flight deck and provide 
procedures following liquid spillage on the center pedestal, installing 
an ICP cover on the flight deck, and further revising the AFM to 
include instructions for ICP cover use. EASA AD 2020-0203 also 
describes procedures for installing a new, water-resistant ICP; 
removing the ICP protective cover; and removing the AFM revisions. 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.

Costs of Compliance

    The FAA estimates that this AD affects 15 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data regarding cost estimates for these parts.

    The FAA has received no definitive data on which to base the cost 
estimates for the on-condition actions specified in this AD.
    According to the manufacturer, some or all of the costs of this AD 
may be 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

    This AD will not have federalism implications under Executive Order 
13132. This AD will 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 that this AD:
    (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.

Project Identifier MCAI-2020-01325-T.

(a) Effective Date

    This airworthiness directive (AD) is effective July 29, 2021.

(b) Affected ADs

    This AD replaces AD 2020-09-14, Amendment 39-19910 (85 FR 30601, 
May 20, 2020) (AD 2020-09-14).

(c) Applicability

    This AD applies to Airbus SAS Model A350-941 and -1041 
airplanes, certificated in any category, as identified in European 
Union Aviation Safety Agency (EASA) AD 2020-0203, dated September

(d) Subject

    Air Transport Association (ATA) of America Code 31, Instruments.

(e) Reason

    This AD was prompted by two reports of abnormal operation of the 
components of the ENG START panel or Electronic Centralized Aircraft 
Monitoring (ECAM) Control Panel (ECP) due to liquid spillage in the 
system, and the subsequent uncommanded engine in-flight shutdown 
(IFSD) of one engine in each case. This AD was also prompted by the 
development of a new, water-resistant integrated control panel (ICP) 
that will address this unsafe condition. The FAA is issuing this AD 
to address the potential for dual-engine IFSD, possibly resulting in 
a forced landing with consequent damage to the airplane and injury 
to occupants.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all
