Airworthiness Directives; Airbus Airplanes - April 27, 2018 - Regulations - VLEX 715201345
Pages 18485-18488
FR Doc No: 2018-08649
Docket No. FAA-2018-0300; Product Identifier 2017-NM-134-AD
SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A318, A319, and A320 series airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -253N, and -
271N airplanes. This proposed AD was prompted by a revision of an airworthiness limitations document that specifies more restrictive maintenance requirements and airworthiness limitations. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate revised fuel airworthiness limitations. We are proposing this AD to address the unsafe condition on these products.
DATES: We must receive comments on this proposed AD by June 11, 2018.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2017-0169, dated September 7, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all Airbus Model A318, A319, and A320 series airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -253N, and -271N airplanes. The MCAI states:
The Fuel Airworthiness Limitations (FAL) for Airbus A320 family aeroplanes, which are approved by EASA, are currently defined and published in the Airbus A318/A319/A320/A321 Airworthiness Limitations Section (ALS) Part 5 document. These instructions have been identified as mandatory for continued airworthiness.
Failure to accomplish these instructions could result in a fuel tank explosion and consequent loss of the aeroplane.
* * * the Federal Aviation Administration (FAA) published Special Federal Aviation Regulation (SFAR) 88, and the Joint Aviation Authorities (JAA) published interim Policy INT/POL/25/12. In response to these regulations, Airbus conducted a design review to develop FAL for Airbus A320 family aeroplanes.
The FAL were specified in Airbus A318/A319/A320/A321 FAL document ref. 95A.1931/05 at issue 04 for A318/A319/A320/A321 aeroplanes. This document was approved by EASA and is now referenced in Airbus A318/A319/A320/A321 ALS Part 5 to comply with EASA policy statement (EASA D2005/CPRO).
Previously, EASA issued AD 2014-0260 which corresponds to FAA AD 2016-20-12, Amendment 39-18678 (81 FR 72507, October 20, 2016) (``AD 2016-20-12'') to require accomplishment of all FAL-related actions as described in ALS Part 5 at Revision 01. ALS Part 5 Revision 02 and 03 were not mandated because no significant changes were introduced with these Revisions. The new ALS Part 5 Revision 04 (hereafter referred to as `the ALS' in this EASA AD) includes new and/or more restrictive requirements and extends the applicability to model A320-251N, A320-271N, A321-251N, A321-253N and A321-271N aeroplanes.
For the reasons described above, this EASA AD retains the requirements of EASA AD 2014-0260, which is superseded, and requires implementation of the actions specified in the ALS.
Relationship of This Proposed AD to AD 2016-20-12
This NPRM would not supersede AD 2016-20-12. Rather, we have determined that a stand-alone AD would be more appropriate to address the changes in the MCAI. This NPRM would require revising the maintenance or inspection program to incorporate the new maintenance requirements and airworthiness limitations. Accomplishment of the proposed actions would then terminate all requirements of AD 2016-20-
Airbus has issued Airbus A318/A319/A320/A321 Airworthiness Limitations Section (ALS) Part 5 Fuel Airworthiness Limitations (FAL), Revision 04, dated April 6, 2017. This service information describes fuel system airworthiness limitations. 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.
This AD requires revisions to certain operator maintenance documents to include new actions (e.g., inspections) and Critical Design Configuration Control Limitations (CDCCLs). Compliance with these actions and CDCCLs 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 according to paragraph (j)(1) of this proposed AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane.
The MCAI specifies that if there are findings from the ALS inspection tasks, corrective actions must be accomplished in accordance with Airbus maintenance documentation. However, this proposed AD does not include that requirement.
Operators of U.S.-registered airplanes are required by general airworthiness and operational regulations to perform maintenance using methods that are acceptable to the FAA. We consider those methods to be adequate to address any corrective actions necessitated by the findings of ALS inspections required by this proposed AD.
However, compliance with AMOCs is normally optional, and we recently became aware that some operators choose to retain the AD-
mandated ALS revision in their fleet-wide maintenance/inspection programs, including those for new airplanes delivered with later ALS revisions, to help standardize the maintenance of the fleet. To ensure that operators comply with the applicable ALS revision for newly delivered airplanes containing a later revision than that specified in an AD, we plan to limit the applicability of ADs that mandate ALS revisions to those airplanes that are subject to an earlier revision of the ALS, either as part of the type design or as mandated by an earlier AD.
This proposed AD therefore would apply to Airbus Model A318, A319, and A320 series airplanes; and Model A321-111, -112, -131, -211, -212, -213, -231, -232, -251N, -253N, and -271N airplanes with an original certificate of airworthiness or original export certificate of airworthiness that was issued on or before the date of approval of the ALS revision identified in this proposed AD. Operators of airplanes with an original certificate of airworthiness or original export certificate of airworthiness issued after that date must comply with the airworthiness limitations specified as part of the approved type design and referenced on the type certificate data sheet.
We have determined that revising the maintenance or inspection program takes an average of 90 work-hours per operator, although we recognize that this number may vary from operator to operator. In the past, we have estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), we have determined that a per-
operator estimate is more accurate than a per-airplane estimate. Therefore, we estimate the total cost per operator to be $7,650 (90 work-hours x $85 per work-hour).

We must receive comments by June 11, 2018.
This AD affects AD 2016-20-12, Amendment 39-18678 (81 FR 72507, October 20, 2016) (``AD 2016-20-12'').
This AD applies to the Airbus airplanes identified in paragraphs (c)(1) through (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 April 6, 2017.
(4) Model A321-111, -112, -131, -211, -212, -213, -231, -232, -
251N, -253N, and -271N airplanes.
This AD was prompted by a revision of an airworthiness limitations document that specifies more restrictive maintenance requirements and airworthiness limitations. We are issuing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Within 90 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 5 Fuel Airworthiness Limitations (FAL), Revision 04, dated April 6, 2017. The initial compliance times for new or revised tasks are the minimum intervals or times specified in Airbus A318/A319/
A320/A321 Airworthiness Limitations Section (ALS) Part 5 Fuel Airworthiness Limitations (FAL), Revision 04, dated April 6, 2017, or within 30 days after the effective date of this AD, whichever occurs later.
(i) Terminating Action for AD 2016-20-12
Accomplishing the actions required by this AD terminates all requirements of AD 2016-20-12.
(2) Contacting the Manufacturer: For any requirement in this AD to obtain corrective actions from a manufacturer, the action must be accomplished using a method approved by the Manager, International Section, Transport Standards Branch, FAA; or the European Aviation Safety Agency (EASA); or Airbus's EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-
