AD 2020-22-16

The FAA is superseding Airworthiness Directive (AD) 2017-25- 04, which applied to certain Airbus SAS Model A318 series airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. The FAA is also superseding AD 2019-03-17, which applies to certain 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, -233, -251N, and -271N airplanes; and Model A321 series airplanes. AD 2019-03-17 required revising the existing maintenance or inspection program, as applicable, to incorporate new maintenance requirements and airworthiness limitations. This AD retains the requirements of AD 2019-03-17 and also requires new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address the unsafe condition on these products.

Final rule.

Adoption of the Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n\n\nSec. 39.13 (Amended) \n\n0 2. The FAA amends Sec. 39.13 by: 0 a. Removing Airworthiness Directive (AD) 2017-25-04, Amendment 39-19118 (82 FR 58098, December 11, 2017); and AD 2019-03-17, Amendment 39-19569 (84 FR 6315, February 27, 2019); and 0 b. Adding the following new AD: \n\n2020-22-16 Airbus SAS: Amendment 39-21312; Docket No. FAA-2020-0590; Product Identifier 2020-NM-055-AD. \n\n(a) Effective Date \n\n\n\tThis AD is effective December 10, 2020. \n\n(b) Affected ADs \n\n\n\tThis AD replaces AD 2017-25-04, Amendment 39-19118 (82 FR 58098, December 11, 2017) (''AD 2017-25-04''); and AD 2019-03-17, Amendment 39-19569 (84 FR 6315, February 27, 2019) (''AD 2019-03-17'').(c) Applicability \n\n\n\tThis AD applies to the Airbus SAS airplanes specified in paragraphs (c)(1) through (4) of this AD, certificated in any category, with an original airworthiness certificate or original export certificate of airworthiness issued on or before January 17, 2020. \n\t(1) Model A318-111, -112, -121, and -122 airplanes. \n\t(2) Model A319-111, -112, -113, -114, -115, -131, -132, -133, - 151N, and -153N airplanes. \n\t(3) Model A320-211, -212, -214, -216, -231, -232, -233, -251N, - 252N, -253N, -271N, -272N, and -273N airplanes. \n\t(4) Model A321-111, -112, -131, -211, -212, -213, -231, -232, - 251N, -252N, -253N, -271N, -272N, -251NX, -252NX, -253NX, -271NX, and -272NX airplanes. \n\n(d) Subject \n\n\n\tAir Transport Association (ATA) of America Code 05, Time Limits/ Maintenance Checks. \n\n(e) Reason \n\n\n\tThis AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address a safety-significant latent failure (that is not annunciated), which, in combination with one or more other specific failures or events, could result in a hazardous or catastrophic failure condition. \n\n(f) Compliance \n\n\n\tComply with this AD within the compliance times specified, unless already done. \n\n(g) Retained Maintenance or Inspection Program Revision, With No Changes \n\n\n\tThis paragraph restates the requirements of paragraph (g) of AD 2019-03-17, with no changes. For airplanes with an original airworthiness certificate or original export certificate of airworthiness issued on or before June 13, 2018: Within 90 days after April 3, 2019 (the effective date of AD 2019-03-17), revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Airbus A318/A319/A320/A321 Airworthiness Limitations Section (ALS) Part 3, Certification Maintenance Requirements (CMR), Revision 06, dated June 13, 2018. The initial compliance time for accomplishing thetasks specified in Airbus A318/A319/A320/A321 Airworthiness Limitations Section (ALS) Part 3, Certification Maintenance Requirements (CMR), Revision 06, dated June 13, 2018, is at the applicable time specified in Airbus A318/A319/A320/A321 ALS Part 3, Certification Maintenance Requirements (CMR), Revision 06, dated June 13, 2018, or within 90 days after April 3, 2019, whichever occurs later. Accomplishing the maintenance or inspection program revision required by paragraph (i) of this AD terminates the requirements of this paragraph. \n\n(h) Retained Restrictions on Alternative Actions and Intervals With a New Exception \n\n\n\tThis paragraph restates the requirements of paragraph (i) of AD 2019-03-17, with a new exception. Except as required by paragraph (i) of this AD, after the maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions (e.g., inspections) or intervals may be used unless the actions or intervals are approved asan alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (l)(1) of this AD. \n\n(i) New Maintenance or Inspection Program Revision \n\n\n\tExcept as specified in paragraph (j) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2020-0067, dated March 23, 2020 (''EASA AD 2020-0067''). Accomplishing the maintenance or inspection program revision required by this paragraph terminates the requirements of paragraph (g) of this AD. \n\n(j) Exceptions to EASA AD 2020-0067 \n\n\n\t(1) The requirements specified in paragraphs (1) and (2) of EASA AD 2020-0067 do not apply to this AD. \n\t(2) Paragraph (3) of EASA AD 2020-0067 specifies revising ''the AMP'' within 12 months after its effective date, but this AD requires revising the existing maintenance or inspection program, as applicable, to incorporate the ''tasks and associated thresholds and intervals''specified in paragraph (3) of EASA AD 2020-0067 within 90 days after the effective date of this AD. \n\t(3) The initial compliance time for doing the tasks specified in paragraph (3) of EASA AD 2020-0067 is at the applicable ''associated thresholds'' specified in paragraph (3) of EASA AD 2020-0067, or within 90 days after the effective date of this AD, whichever occurs later. \n\t(4) The provisions specified in paragraphs (4) and (5) of EASA AD 2020-0067 do not apply to this AD. \n\t(5) The ''Remarks'' section of EASA AD 2020-0067 does not apply to this AD. \n\n(k) New Provisions for Alternative Actions and Intervals \n\n\n\tAfter the maintenance or inspection program has been revised as required by paragraph (i) of this AD, no alternative actions (e.g., inspections) or intervals are allowed unless they are approved as specified in the provisions of the ''Ref. Publications'' section of EASA AD 2020-0067. \n\n(l) Other FAA AD Provisions \n\n\n\tThe following provisions also apply to this AD:(1) Alternative Methods of Compliance (AMOCs): The Manager, Large Aircraft Section, International Validation Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.

Discussion \n\n\n\tThe EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020-0067, dated March 23, 2020 (''EASA AD 2020-0067'') (also referred to as the Mandatory Continuing Airworthiness Information, or ''the MCAI''), to correct an unsafe condition for all Airbus SAS Model A318-111, -112, -121, and -122 airplanes; Model A319-111, -112, -113, -114, -115, \n\n((Page 70440)) \n\n-131, -132, -133, -151N, and -153N airplanes; Model A320-211, -212, - 214, -215, -216, -231, -232, -233, -251N, -252N, -253N, -271N, -272N, and -273N airplanes; Model A321-111, -112, -131, -211, -212, -213, - 231, -232, -251N, -252N, -253N, -271N, -272N, -251NX, -252NX, -253NX, - 271NX, and -272NX airplanes. Model A320-215 airplanes are not certificated by the FAA and are not included on the U.S. type certificate data sheet; this AD therefore does not include those airplanes in the applicability. \n\tThe FAA issued a notice of proposedrulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2017-25-04, Amendment 39-19118 (82 FR 58098, December 11, 2017) (''AD 2017-25-04''). AD 2017-25-04 applied to certain Airbus SAS Model A318-111, -112, -121, and -122 airplanes; Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes. \n\tThe NPRM also proposed to supersede AD 2019-03-17, Amendment 39- 19569 (84 FR 6315, February 27, 2019) (''AD 2019-03-17''). AD 2019-03- 17 applied to certain 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, -233, -251N, and -271N airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, - 232, -251N, -251NX, -252N, -252NX, -253N, -253NX, -271N, -271NX, -272N, and -272NX airplanes. \n\tThe NPRM published in the Federal Register on June 17, 2020 (85 FR 36519). The NPRM was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The NPRM proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD. \n\tThe FAA is issuing this AD to address a safety-significant latent failure (that is not annunciated), which, in combination with one or more other specific failures or events, could result in a hazardous or catastrophic failure condition. See the MCAI for additional background information. \n\nComments \n\n\n\tThe FAA gave the public the opportunity to participate in developing this final rule. The following presents the comments received on the NPRM and the FAA's response to each comment. United Airlines expressed support for the NPRM. \n\nRequest To Confirm Intent To Allow Use of Later ALS Revisions \n\n\n\tDelta Air Lines (DAL) requested confirmation that the FAA intended to allow the use of later ALS revisions to comply with the proposed AD. The commenter noted that previous ADs required an alternative method of compliance (AMOC) to use a later ALS revision. \n\tThe FAA confirms that it intends to allow the use of applicable later ALS revisions to comply with the requirements of this AD. This AD refers to EASA AD 2020-0067 as the appropriate source of service information for accomplishing the required actions. EASA AD 2020-0067 includes the Ref. Publications section, which accepts the use of later approved variations or revisions of the referenced ALS document for compliance. Therefore, later approved ALS revisions are acceptable as specified in paragraph (k) of this final rule. The FAA has also updated the language in paragraph (k) to be consistent with other rules using this format but the substance of this requirement has not changed. \n\nRequest To Allow AMOC Approved Alternative Actions and Intervals \n\n\n\tDelta Air Lines requested revising paragraph (k) of the proposed AD to allow for alternative actions and intervals that are approved in accordance with the procedures specified in paragraph (l)(1) of the proposed AD. The FAA infers a desire to maintain consistency with other ADs. \n\tThe FAA acknowledges the commenter's request and provides clarification that, if applicable, requesting an AMOC is always an option; therefore, it is not necessary to revise paragraph (k) of this AD. This AD has not been changed regarding this request. \n\nConclusion \n\n\n\tThe FAA reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule as proposed with minor editorial changes. The FAA has determined that these minor changes: \n\tAre consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and \n\tDo not add any additional burden upon the public than was already proposed in the NPRM. \n\nRelated IBR Material Under 1 CFR Part 51 \n\n\n\tEASA AD 2020-0067 describes airworthiness limitations for certification maintenance requirements. \n\tThis AD also requires Airbus A318/A319/A320/A321 Airworthiness Limitations Section (ALS) Part 3, Certification Maintenance Requirements (CMR), Revision 06, dated June 13, 2018, which the Director of the Federal Register approved for incorporation by reference as of April 3, 2019 (84 FR 6315, February 27, 2019). \n\tThis 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. \n\nCosts of Compliance \n\n\n\tThe FAA estimates that this AD affects 1,553 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: \n\tThe FAA estimates the total cost per operator for the retained actions from AD 2019-03-17 to be $7,650 (90 work-hours x $85 per work- hour). \n\tThe 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. \n\tThe FAA estimates the total cost per operator for the new actions to be $7,650 (90 work-hours x $85 per work-hour). \n\nAuthority for This Rulemaking \n\n\n\tTitle 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. \n\tThe 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 \n\n((Page 70441)) \n\ndevelop on products identified in this rulemaking action. \n\nRegulatory Findings \n\n\n\tThis 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. \n\tFor the reasons discussed above, I certify that this AD: \n\t(1) Is not a ''significant regulatory action'' under Executive Order 12866, \n\t(2) Will not affect intrastate aviation in Alaska, and \n\t(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. \n\nList of Subjects in 14 CFR Part 39 \n\n\n\tAir transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
