# AGENCY:

Federal Aviation Administration (FAA), DOT.

# ACTION:

Notice of proposed rulemaking (NPRM).

# SUMMARY:

The FAA proposes to supersede Airworthiness Directive (AD) 2016-10-08, AD 2017-05-10, and AD 2019-01-05, which apply to certain Airbus SAS Model A330-200, -200 Freighter, and -300 series airplanes; and AD 2019-20-13, which applies to certain Airbus SAS Model A330-200, A330-200 Freighter, A330-300, A340-200, A340-300, A340-500, and A340-600 series airplanes. AD 2016-10-08 requires determining the flight cycles accumulated on certain trimmable horizontal stabilizer actuators (THSAs), and replacing the THSA if necessary. AD 2017-05-10, AD 2019-01-05, and AD 2019-20-13 require revising the existing maintenance or inspection program, as applicable. Since the FAA issued those ADs, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would 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. The FAA is proposing this AD to address the unsafe condition on these products.

## Background

The FAA issued AD 2016-10-08, Amendment 39-18519 (81 FR 31844, May 20, 2016) (AD 2016-10-08), which applies to certain Airbus SAS Model A330-200, A330-200 Freighter, A330-300, A340-200, A340-300, A340-500, and A340-600 series airplanes. Airbus SAS Model A340-200, A340-300, A340-500, and A340-600 series airplanes were included in AD 2016-10-08, but are not included in this proposed AD. Airbus SAS Model A340-200, A340-300, A340-500, and A340-600 series airplanes are not included in this proposed AD because EASA included these airplanes in EASA AD 2021-0250, dated November 17, 2021 (EASA AD 2021-0250), and the FAA has added the MCAI to the required airworthiness actions list (RAAL) for Model A340 airplanes. AD 2016-10-08 requires inspecting certain THSAs to determine the number of total flight cycles the THSA has accumulated, and replacing the THSA if necessary. The FAA issued AD 2016-10-08 to detect and correct premature wear of the carbon friction disks on the no-back brake of the THSA. Such a condition could lead to reduced braking efficiency in certain load conditions and, in conjunction with the inability of the power gear train to keep the ball screw in its last commanded position, could result in uncommanded movements of the trimmable horizontal stabilizer and loss of control of the airplane.

The FAA issued AD 2017-05-10, Amendment 39-18821 (82 FR 13379, March 13, 2017) (AD 2017-05-10), which applies to certain Airbus SAS Model A330-200, A330-200 Freighter, and A330-300 series airplanes. AD 2017-05-10 requires revising the maintenance or inspection program to incorporate new maintenance requirements and airworthiness limitations. The FAA issued AD 2017-05-10 to prevent reduced structural integrity and reduced control of these airplanes due to the failure of system components.

The FAA issued AD 2019-01-05, Amendment 39-19544 (84 FR 4310, February 15, 2019) (AD 2019-01-05), which applies to certain Airbus SAS Model A330-200, A330-200 Freighter, and A330-300 series airplanes. AD 2019-01-05 requires revising the existing maintenance or inspection program to incorporate new maintenance requirements and airworthiness limitations. The FAA issued AD 2019-01-05 to prevent reduced airplane control due to the failure of system components. AD 2019-01-05 specifies that accomplishing the revision required by paragraph (g) of that AD terminates all requirements of AD 2017-05-10.

The FAA issued AD 2019-20-13, Amendment 39-19766 (84 FR 56378, October 22, 2019) (AD 2019-20-13), which applies to certain Airbus SAS Model A330-200, A330-200 Freighter, and A330-300 series airplanes. AD 2019-20-13 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA issued AD 2019-20-13 to address the failure of system components, which could reduce the controllability of the airplane. AD 2019-20-13 specifies that accomplishing the actions required by that AD terminates all requirements of AD 2019-01-05. Additionally, AD 2019-20-13 specifies that accomplishing the action required by task number 274400-00004-1-E of Airbus A330 Airworthiness Limitations Section (ALS) Part 4, System Equipment Maintenance Requirements (SEMR), Revision 07, dated October 15, 2018, within the compliance time specified for that task in Airbus A330 Airworthiness Limitations Section (ALS) Part 4, System Equipment Maintenance Requirements (SEMR), Revision 07, dated October 15, 2018, terminates all requirements of AD 2017-25-13, Amendment 39-19127 (82 FR 59960, December 18, 2017) (AD 2017-25-13), for Airbus SAS Model A330-200, -200 Freighter, and -300 series airplanes only. Lastly, AD 2019-20-13 specifies that accomplishing the action required by task number 213100-00001-1-E of Airbus A330 Airworthiness Limitations Section (ALS) Part 4, System Equipment Maintenance Requirements (SEMR), Revision 07, dated October 15, 2018, within the compliance time specified for that task in Airbus A330 Airworthiness Limitations Section (ALS) Part 4, System Equipment Maintenance Requirements (SEMR), Revision 07, dated October 15, 2018, terminates all requirements of AD 2014-16-22, Amendment 39-17946 (79 FR 49442, August 21, 2014) (AD 2014-16-22) for Airbus SAS Model A330-200, -200 Freighter, and -300 series airplanes only.

## Actions Since AD 2016-10-08, AD 2017-05-10, AD 2019-01-05, and AD 2019-20-13 Were Issued

Since the FAA issued AD 2016-10-08, AD 2017-05-10, AD 2019-01-05, and AD 2019-20-13, the FAA has determined that new or more restrictive airworthiness limitations are necessary. The required actions mandated in AD 2016-10-08 are incorporated into Airbus A330 Airworthiness Limitations Section (ALS) Part 4, System Equipment Maintenance Requirements (SEMR), Revision 08, dated July 1, 2021 (which is referred to in EASA AD 2021-0250, dated November 17, 2021) (EASA AD 2021-0250) (also referred to as the MCAI).

EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021-0250 to correct an unsafe condition for all Airbus SAS Model A330-201, -202, -203, -223, and -243 airplanes; Model A330-223F and -243F airplanes; Model A330-301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes; Model A330-841 airplanes; and Model A330-941 airplanes.

Airplanes with an original airworthiness certificate or original export certificate of airworthiness issued after July 1, 2021, must comply with the airworthiness limitations specified as part of the approved type design and referenced on the type certificate data sheet; this 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 failure of system components, which could reduce the controllability of the airplane. See the MCAI for additional background information.

## Related Service Information Under 1 CFR Part 51

EASA AD 2021-0250 describes airworthiness limitations for system equipment maintenance requirements.

This proposed AD would require Airbus Service Bulletin A330-27-3199, dated July 15, 2014, which the Director of the Federal Register approved for incorporation by reference as of June 24, 2016 (81 FR 31844, May 20, 2016).

This proposed AD would also require A330 Airworthiness Limitations Section (ALS) Part 4, System Equipment Maintenance Requirements (SEMR), Revision 07, dated October 15, 2018, which the Director of the Federal Register approved for incorporation by reference as of November 26, 2019 (84 FR 56378, October 22, 2019).

                    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.                          ( print page 37456)    

## 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 retain the requirements of AD 2016-10-08 and AD 2019-20-13. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, which are specified in EASA AD 2021-0250 described previously, as proposed for incorporation by reference. Accomplishing the actions required by this proposed AD would terminate all requirements of AD 2014-16-22 for Airbus SAS Model A330-200, -200 Freighter, and -300 series airplanes only, and would terminate all requirements of AD 2017-25-13 for Airbus SAS Model A330-200, -200 Freighter, and -300 series airplanes only. Any differences with EASA AD 2021-0250 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 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 (s)(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 2021-0250 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2021-0250 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 2021-0250 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 2021-0250. Service information required by EASA AD 2021-0250 for compliance will be available at                     *https://www.regulations.gov*                     by searching for and locating Docket No. FAA-2022-0682 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) or intervals 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 FAA 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 proposed AD affects 138 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 2016-10-08 to be $255 per product (3 work-hours × $85 per work-hour) for inspecting the THSA for a total cost for U.S. operators of $35,190. The retained on-condition cost for AD 2016-10-08 is $724,511 per product (23 work-hours × $85 per work-hour). The FAA estimates the total cost per operator for the retained actions from AD 2019-20-13 to be $7,650 (90 work-hours × $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 × $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                           ( print page 37457)                        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.
