AD 2017-19-24

We are superseding Airworthiness Directive (AD) 2014-26-10, which applied to all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2014-26-10 required revising the maintenance or inspection program to incorporate maintenance requirements and airworthiness limitations. This new AD requires revising the maintenance or inspection program, as applicable, to incorporate new or revised airworthiness limitation requirements. This AD was prompted by a determination that more restrictive maintenance instructions and airworthiness limitations are necessary. We are 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 removing Airworthiness Directive (AD) 2014-26-10, Amendment 39-18061 (80 FR 2813, January 21, 2015), and adding the following new AD: \n\n2017-19-24 Airbus: Amendment 39-19054; Docket No. FAA-2017-0248; Product Identifier 2016-NM-088-AD. \n\n(a) Effective Date \n\n\n\tThis AD is effective November 1, 2017. \n\n(b) Affected ADs \n\n\n\tThis AD replaces AD 2014-26-10, Amendment 39-18061 (80 FR 2813, January 21, 2015) (''AD 2014-26-10''). \n\n(c) Applicability \n\n\n\tThis AD applies to the Airbus airplanes identified in paragraphs (c)(1), (c)(2), (c)(3), and (c)(4) of this AD; certificated in any category; with an original certificate of airworthiness or original export certificate of airworthiness issued on or before December 21, 2015. \n\t(1) Model A318-111, -112, -121, and -122 airplanes. \n\t(2) Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes. \n\t(3) Model A320-211, -212, -214, -231, -232, and -233 airplanes. \n\t(4) Model A321-111, -112, -131, -211, -212, -213, -231, and -232 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 more restrictive maintenance instructions and airworthiness limitations are necessary. We are issuing this AD to mitigate the risks associated with aging effects of airplane systems. Such aging effects could change the characteristics of the systems leading to an increased potential for failure, which could result in failure of certain life-limited parts, and reduced structural integrity or reduced controllability of theairplane. \n\n(f) Compliance \n\n\n\tComply with this AD within the compliance times specified, unless already done. \n\n(g) Retained Requirement: Maintenance or Inspection Program Revision, With New Reference To Terminating Action \n\n\n\tThis paragraph restates the requirements of paragraph (g) of AD 2014-26-10, with new reference to terminating action. Within 30 days after February 25, 2015 (the effective date of AD 2014-26-10): Revise the maintenance or inspection program, as applicable, to incorporate Airbus A318/A319/A320/A321 Airworthiness Limitations Section, ALS Part 4, ''Aging Systems Maintenance,'' Revision 01, dated June 15, 2012. The initial compliance time for doing the actions is at the applicable time specified in Airbus A318/A319/ A320/A321 Airworthiness Limitations Section, ALS Part 4, ''Aging Systems Maintenance,'' Revision 01, dated June 15, 2012; or within 2 weeks after revising the maintenance or inspection program; whichever occurs later. Accomplishing the actionsspecified in paragraph (i) of this AD terminates the requirements of this paragraph. \n\n(h) Retained Requirement: No Alternative Actions or Intervals, With New Paragraph Reference \n\n\n\tThis paragraph restates the requirements of paragraph (h) of AD 2014-26-10, with a new paragraph reference. Except as required by paragraph (i) of this AD, after accomplishment of the revision 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 as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (k)(1) of this AD. \n\n(i) New Requirement: Maintenance or Inspection Program Revision \n\n\n\tWithin 30 days after the effective date of this AD: Revise the maintenance or inspection program, as applicable, to incorporate Airbus A318/A319/A320/A321 Airworthiness Limitations Section (ALS) Part 4, ''System Equipment Maintenance Requirements (SEMR),'' Revision 03 at Issue 02, dated January 22, 2016. The initial compliance time for doing the actions is at the applicable time specified in Airbus A318/A319/A320/A321 Airworthiness Limitations Section, ALS Part 4, ''System Equipment Maintenance Requirements (SEMR),'' Revision 03 at Issue 02, dated January 22, 2016; or within 2 weeks after revising the maintenance or inspection program; whichever occurs later. Accomplishing the actions specified in this paragraph terminates the requirements of paragraph (g) of this AD. \n\n((Page 44903)) \n\n(j) New Provision: No Alternative Actions or Intervals \n\n\n\tAfter the action required by paragraph (i) of this AD has been done, no alternative actions (e.g., inspections) or intervals may be used unless the actions or intervals are approved as an AMOC in accordance with the procedures specified in paragraph (k)(1) of this AD. \n\n(k) Other FAA AD Provisions \n\n\n\tThe following provisions also apply to this AD: \n\t(1) Alternative Methods of Compliance (AMOCs):The Manager, International Branch, Transport Standards 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\tWe issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2014-26-10, Amendment 39-18061 (80 FR 2813, January 21, 2015) (''AD 2014-26-10''). AD 2014-26-10 applied to all Airbus Model A318, A319, A320, and A321 series airplanes. The NPRM published in the Federal Register on April 13, 2017 (82 FR 17770). The NPRM was prompted by a determination that more restrictive maintenance instructions and airworthiness limitations are necessary. The NPRM proposed to require revising the maintenance or inspection program, as applicable, to incorporate new or revised airworthiness limitation requirements. The NPRM also proposed to remove airplanes from the applicability. We are issuing this AD to mitigate the risks associated with aging effects of airplane systems. Such aging effects could change the characteristics of the systems leading to an increased potential for failure, which could result in failure of certain life-limited parts, and reduced structural integrity or reduced controllability of the airplane. \n\tThe European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2016-0093, dated May 13, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ''the MCAI''), to correct an unsafe condition for all Airbus Model A318, A319, A320, and A321 series airplanes. The MCAI states: \n\n\n\tThe airworthiness limitations for Airbus A320 family aeroplanes are currently defined and published in Airbus A318/A319/A320/A321 Airworthiness Limitations Section (ALS) documents. The airworthiness limitations applicable to the System Equipment Maintenance Requirements, which are approved by (European Aviation Safety Agency) EASA, are specified in ALS Part 4. \n\tThe instructions contained in the ALS Part 4 have been identified as mandatory actions for continued airworthiness. Failure to comply with these instructions could result in an unsafe condition. \n\tPreviously, EASA issued AD 2013-0146 (which corresponds to FAA AD 2014-26-10) to require accomplishment of all maintenance actions as described in ALS Part 4 at Revision 01. The new ALS Part 4 Revision 03 (hereafter referred to as 'the ALS' in this AD) includes new and/or more restrictive requirements. ALS Part 4 Revision 03, issue 02, has been released to include editorial changes. \n\tFor the reason described above, this (EASA) AD retains the requirements of EASA AD 2013-0146, which is superseded, and requires accomplishment of the actions specified in the ALS. \n\n\n\tYou may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017- 0248. \n\nComments \n\n\n\tWe gave the public the opportunity to participate in developing this AD. We considered the comments received. Camp Systems International, Daniel Systems Inc., and United Airlines supported the NPRM. \n\nRequest ToIncorporate Current ALS Revision \n\n\n\tAmerican Airlines (AAL) asked that a provision be incorporated into the proposed AD to approve use of Airbus A318/A319/A320/A321 ALS Part 4, ''System Equipment Maintenance Requirements (SEMR)'', Revision 05, dated April 6, 2017 (''ALS Part 4, Revision 05''), as an additional means of compliance with the maintenance or inspection program. AAL stated that ALS Part 4, Revision 05 is the latest revision level for ALS Part 4, and approving it would potentially alleviate a future alternative method of compliance (AMOC) request. \n\tWe acknowledge the commenter's concern. We have issued global AMOCs to AD 2014-26-10, which allow all operators of U.S.-registered airplanes to use Airbus A318/A319/A320/A321 ALS Part 4, ''System Equipment Maintenance Requirements (SEMR)'', Revision 04, dated July 6, 2016, and Airbus A318/A319/A320/A321 ALS Part 4, ''System Equipment Maintenance Requirements (SEMR)'', Revision 05, dated April 6, 2017. These AMOCs are includedin paragraph (k)(1)(ii) of this AD, which states that AMOCs approved previously for AD 2014-26-10 are approved as AMOCs for the corresponding provisions of paragraph (g) of this AD. In addition, these AMOCs are also applicable to the revision required by paragraph (i) of this AD. Therefore, we have added paragraph (k)(1)(iii) to this AD to specify the previous AMOCs that are approved for the provisions of paragraph (i) of this AD. \n\nConclusion \n\n\n\tWe reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting this AD with the change described previously and minor editorial changes. We have determined that these minor changes: \n\tAre consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and \n\tDo not add any additional burden upon the public than was already proposed in the NPRM. \n\tWe also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. \n\nRelated Service Information Under 1 CFR part 51 \n\n\n\tAirbus has issued Airbus A318/A319/A320/A321 ALS Part 4, ''System Equipment Maintenance Requirements (SEMR),'' Revision 03 at Issue 02, dated January 22, 2016. This service information describes preventive maintenance requirements and includes updated inspections and intervals to be incorporated into the maintenance or inspection program. This service information 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\tWe estimate that this AD affects 1,032 airplanes of U.S. registry. \n\n((Page 44902)) \n\n\n\tThe actions required by AD 2014-26-10, and retained in this AD take about 1 work-hour per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the actions that are required by AD 2014-26-10 is $85per product. \n\tWe also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD on U.S. operators to be $87,720, or $85 per product. \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\tWe are 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. \n\tThis proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. \n\nRegulatory Findings \n\n\n\tWe determined that 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 the various levels of government. \n\tFor the reasons discussed above, I certify that this AD: \n\t1. Is not a ''significant regulatory action'' under Executive Order 12866; \n\t2. Is not a ''significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); \n\t3. Will not affect intrastate aviation in Alaska; and \n\t4. Will not have a significant economic impact, positive or negative, on a substantial number of small 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.
