2021-13123. 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 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:

• Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and
• 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:

Estimated Costs for Required Actions

Action	Labor cost	Parts cost	Cost per product	Cost on U.S. operators
Retained AFM revision from AD 2020-09-14	1 work-hour × $85 per hour = $85	$0	$85	$1,105.
Retained installation from AD 2020-09-14	2 work-hours × $85 per hour = $170	(*)	170 *	2,210.*
New actions	Up to 42 work-hours × $85 per hour = Up to $3,570	5,700	Up to $9,270	Up to $139,050.
* 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.
