2022-27297. 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) 2020-21-10, which applies to certain Airbus SAS Model A318, A320, and A321 series airplanes; and Model A319-111, -112, -113, -114, -115, -131, -132, -133, -151N, and -153N airplanes; and AD 2022-07-08, which applies to all Airbus SAS Model A318, A319, A320 and A321 series airplanes. AD 2020-21-10 and AD 2022-07-08 require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2020-21-10 and AD 2022-07-08, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require the actions in AD 2020-21-10 and AD 2022-07-08 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.

Background

The FAA issued AD 2020-21-10, Amendment 39-21283 (85 FR 65190, October 15, 2020) (AD 2020-21-10), for certain Airbus SAS Model A318, A320, and A321 series airplanes, and Model A319-111, -112, -113, -114, -115, -131, -132, -133, -151N, and -153N airplanes. AD 2020-21-10 was prompted by EASA AD 2020-0034, dated February 25, 2020 (EASA AD 2020-0034).

AD 2020-21-10 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA issued AD 2020-21-10 to address the risks associated with the effects of aging on airplane systems. Such effects could change system characteristics, leading to an increased potential for failure of certain life-limited parts, and reduced structural integrity or controllability of the airplane.

The FAA also issued AD 2022-07-08, Amendment 39-21996 (87 FR 22117, April 14, 2022) (AD 2022-07-08), for all Airbus SAS Model A318, A319, A320, and A321 series airplanes. AD 2022-07-08 was prompted by EASA AD 2020-0270, dated December 7, 2020 (EASA AD 2020-0270).

AD 2022-07-08 requires inspections of certain trimmable horizontal stabilizer actuators (THSAs) and replacement if necessary, and revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA issued AD 2022-07-08 to address premature wear of the carbon friction disks on the no-back brake (NBB) of the THSA, which 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. AD 2022-07-08 specifies that accomplishing the revision required by that AD terminates certain requirements of AD 2020-21-10. This proposed AD would continue to allow that termination.

Actions Since AD 2020-21-10 and AD 2022-07-08 Were Issued

Since the FAA issued AD 2020-21-10 and AD 2022-07-08, EASA issued AD 2022-0102, dated June 8, 2022 (EASA AD 2022-0102) (referred to after this as the MCAI), for all Airbus SAS Model A318-111, -112, -121, and -122 airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, -133, -151N, -153N, and -171N airplanes; Model A320-211, -212, -214, -215, -216, -231, -232, -233, -251N, -252N, -253N, -271N, -272N, and -273N airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, 232, -251N, -251NX, -252N, -252NX, -253N, -253NX, -271N, -271NX, -272N, and -272NX airplanes. Model A320-215 airplanes are not certified by the FAA and are not included on the U.S. type certificate data sheet; this proposed AD therefore does not include those airplanes in the applicability. The MCAI states that new or more restrictive airworthiness limitations have been developed. EASA AD 2022-0102 superseded EASA AD 2020-0034, dated February 25, 2020, and EASA AD 2020-0270, dated December 7, 2020 (which correspond to FAA AD 2020-21-10 and AD 2022-07-08, respectively).

Airplanes with an original airworthiness certificate or original export certificate of airworthiness issued after February 18, 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.

EASA AD 2022-0102 specifies that the revised airworthiness limitations section (ALS) document contains new tasks 274000-00002-1-E and 274000-00003-1-E, which cover the inspections, corrective actions, and reporting previously required by EASA AD 2017-0237, dated December 4, 2017 (which corresponds to FAA AD 2018-23-02, Amendment 39-19488 (83 FR 59278, November 23, 2018) (AD 2018-23-02)). Accomplishing the revision of the existing maintenance or inspection program required by paragraph (n) of this proposed AD would therefore terminate the requirements of paragraphs (g) through (k) of AD 2018-23-02 for Airbus SAS Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes only.

AD 2022-07-08 requires that task 274000-00004-1-E (NBB carbon disk replacement) be accomplished using only certain Airbus service information (“SB A320-27-1242”), and does not allow using certain other vendor [UTC] service information (“VSB 47145-27-17”). The FAA has determined that this restriction is no longer necessary, as both service bulletins provide adequate instructions for accomplishing the replacement.

The FAA is proposing this AD to address the risks associated with the effects of aging on airplane systems. Such effects could change system characteristics. The unsafe condition, if not addressed, could result in an increased potential for failure of certain life-limited parts, and reduced structural integrity of the airplane. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA-2022-1645.

Related Service Information Under 1 CFR Part 51

The FAA reviewed EASA AD 2022-0102, dated June 8, 2022. This service information specifies new or more restrictive airworthiness limitations for airplane structures and safe life limits.

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 ADDRESSES .

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 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 the same type design.

Proposed AD Requirements in This NPRM

This proposed AD would retain all of the requirements of AD 2020-21-10 and AD 2022-07-08. 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 2022-0102 already described, as proposed for IBR. Any differences with EASA AD 2022-0102 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 (r)(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 retain the IBR of EASA AD 2020-0034 and EASA AD 2020-0270 and incorporate EASA AD 2022-0102 by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA ADs 2020-0034, 2020-0270, and 2022-0102 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 ADs 2020-0034, 2020-0270, or 2022-0102 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 ADs 2020-0034, 2020-0270, or 2022-0102. Service information required by EASA ADs 2020-0034, 2020-0270, and 2022-0102 for compliance will be available at regulations.gov by searching for and locating Docket No. FAA-2022-1645 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 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 actions or intervals.

Costs of Compliance

The FAA estimates that this AD, if adopted as proposed, would affect 1,864 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 2020-21-10 to be $7,650 (90 work-hours × $85 per work-hour).

The FAA estimates the total cost per operator for the retained actions from AD 2022-07-08 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 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.
