Airworthiness Directives; Airbus Airplanes

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Final rule.

SUMMARY:

We are superseding Airworthiness Directive (AD) 2012-20-07 for certain Airbus Model A318, A319, A320, and A321 series airplanes. AD 2012-20-07 required revising the Airworthiness Limitations section (ALS) of the Instructions for Continued Airworthiness (ICA) to incorporate new limitations for fuel tank systems, and revising the maintenance program to incorporate revised fuel maintenance and inspection tasks. This new AD requires revising the maintenance or inspection program to incorporate revised fuel airworthiness limitations. This AD was prompted by Airbus issuing more restrictive maintenance requirements and/or 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.

DATES:

This AD is effective November 25, 2016.

SUPPLEMENTARY INFORMATION:

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2012-20-07, Amendment 39-17213 (77 FR 63716, October 17, 2012) (“AD 2012-20-07”). AD 2012-20-07 applied to all Airbus Model A318, A319, A320, and A321 series airplanes. The NPRM published in the Federal Register on April 14, 2016 (81 FR 22033). The NPRM was prompted by Airbus issuing more restrictive maintenance requirements and/or airworthiness limitations. The NPRM proposed to continue to require revising the ALS of the ICA to incorporate new limitations for fuel tank systems in accordance with the type design, and revising the maintenance program to incorporate revised fuel maintenance and inspection tasks. The NPRM also proposed to require revising the maintenance or inspection program to incorporate revised fuel 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.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014-0260, dated December 5, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition. The MCAI states:

Prompted by an accident * * *, 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 Fuel Airworthiness Limitations (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 the European Aviation Safety Agency (EASA) and is now referenced in Airbus A318/A319/A320/A321 ALS Part 5 to comply with EASA policy statement (EASA D2005/CPRO).

Failure to comply with items as identified in Airbus A318/A319/A320/A321 ALS Part 5 could result in a fuel tank explosion and consequent loss of the aeroplane.

For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2011-0155R1, which is superseded [and which corresponds to FAA AD 2012-20-07], and requires implementation of the new or more restrictive maintenance requirements and/or airworthiness limitations as specified in Airbus A318/A319/A320/A321 ALS Part 5 at Rev.01.

The required action is revising the maintenance or inspection program to incorporate revised fuel airworthiness limitations. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-5589.

Comments

We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM and the FAA's response to each comment.

Support for the NPRM

The Airline Pilots Association, International stated that it supports the intent of the NPRM.

Request To Clarify and Revise Applicability

American Airlines (AAL) asked if airplanes with an operating certificate issued after the applicability date of July 19, 2014, in paragraph (c) of the NPRM, are excluded from the proposed requirements. AAL stated that it has received several Model A321 airplanes after July 19, 2014, that have the fuel tank inerting system (FTIS) installed in production; AAL thinks the requirement to replace the air separation module (ASM) having P/N 2060017-102 every 27,000 flight hours and other tasks listed in Airbus A318/A319/A320/A321 ALS Part 5, Fuel Airworthiness Limitations, Revision 01, dated July 9, 2014 (“ALS part 5 R01”), should apply to these airplanes. AAL requested that we revise the applicability by removing the July 19, 2014, date in paragraph (c) of the proposed AD and revising the applicability to be in sync with ALS part 5 R01.

We partially agree with AAL's requests. We agree that clarification is necessary. AAL stated that, for airplanes with the FTIS installed, operators must incorporate the ALS associated with the system in accordance with ALS part 5 R01. However, we would like to reiterate the information stated in the preamble of the NPRM under “Airworthiness Limitations Based on Type Design,” which states that operators of airplanes with an original certificate of airworthiness or original export certificate of airworthiness issued after July 19, 2014, must comply with the airworthiness limitations specified as part of the approved type design. These airplanes are not subject to the requirements of this AD. Therefore, if an airplane's type design includes systems such as the FTIS, then the corresponding ALS specified as part of the approved type design should address those systems as appropriate, and must be incorporated into the maintenance/inspection programs. Therefore, we disagree with AAL's request to change the applicability of this AD. We have not changed this AD in this regard.

Request To Remove Task Requirement

AAL requested that we remove “Task 470000-05-1” from paragraph (j)(2) of the proposed AD because this is a one-time task, which AAL has completed.

We do not agree with AAL's request. Even if the current U.S. registered fleet already complies with the requirements of “Task 470000-05-1” in paragraph (j)(2) of this AD, the requirement is still necessary to ensure that any affected airplane imported and placed on the U.S. register in the future complies as well. We have not changed this AD in this regard.

Request To Revise Service Information

AAL requested that we revise paragraph (j)(2)(ii) of the proposed AD to include Airbus Service Bulletins A320-47-1025 and A320-47-1026, which apply to AAL's airplanes.

We do not agree with AAL's request. AAL's suggested changes are for the retained requirements of AD 2012-20-07. Accomplishing the requirements of paragraph (l) of this AD terminates the retained requirements of paragraph (j) of this AD. Therefore, no change to this AD is needed in this regard.

Request To Revise Service Information

AAL requested that we revise table 1 to paragraph (j)(4) of the proposed AD to include ASMs having P/N 2060017-103 to ensure that these parts are being tracked for removal every 27,000 flight hours. AAL stated that 25 airplanes in its fleet are equipped with ASMs having P/N 2060017-103.

We do not agree with AAL's request. The suggested changes are for the retained requirements of AD 2012-20-07. Adding additional requirements to the retained requirements could put operators out of compliance. As previously stated, incorporating the requirements of paragraph (l) of this AD terminates the requirements of paragraph (j) of this AD. Therefore, no change to this AD is needed in this regard.

Request for Alternative Method of Compliance (AMOC) Approval

Spirit Airlines requested that we revise the NPRM to specify that AMOC ANM-116-16-248 is approved as a means of compliance for the actions proposed in paragraph (i) of the proposed AD. Spirit Airlines stated that this AMOC permits the use of Airbus A318/A319/A320/A321 ALS Part 5, Fuel Airworthiness Limitations, Revision 02, dated December 18, 2015.

We agree with Spirit Airlines that AMOC ANM-116-16-248 is approved as a method of compliance for the corresponding provisions of paragraph (i) of this AD. However, no change is necessary to this AD because paragraph (n)(1)(ii) of this AD already specifies that AMOCs approved previously for AD 2012-20-07 are approved as AMOCs for the corresponding provisions of this AD.

Conclusion

We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these changes:

• Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
• Do not add any additional burden upon the public than was already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

Airbus has issued A318/A319/A320/A321 ALS Part 5, Fuel Airworthiness Limitations, Revision 01, dated July 9, 2014. The 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.

Costs of Compliance

We estimate that this AD affects 953 airplanes of U.S. registry.

The actions required by AD 2012-20-07 and retained in this AD take about 4 work-hours 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 2012-20-07 is $340 per product.

We 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 $81,005, or $85 per product.

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.

We 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.

Regulatory Findings

We 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 among the various levels of government.

For the reasons discussed above, I certify that this AD:

1. Is not a “significant regulatory action” under Executive Order 12866;

2. Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);

3. Will not affect intrastate aviation in Alaska; and

4. 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.

This paragraph restates the requirements of paragraph (k) of AD 2012-20-07, with no changes. Except as required by paragraph (l) of this AD, after accomplishing the revisions required by paragraph (j) of this AD, no alternative actions (e.g., inspections), intervals, and/or CDCCLs may be used other than those specified in Airbus A318/A319/A320/A321 ALS Part 5—Fuel Airworthiness Limitations, dated February 28, 2006, as defined in Airbus A318/A319/A320/A321 Fuel Airworthiness Limitations, Document 95A.1931/05, Issue 4, dated August 26, 2010, unless the actions, intervals, and/or CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (n)(1) of this AD.

(l) New Requirement of This AD: Revise the Maintenance or Inspection Program

Within 60 days after the effective date of this AD, revise the maintenance or inspection program, as applicable, by incorporating the fuel airworthiness limitations (e.g., life limits, tasks, and CDCCLs, and associated thresholds and intervals) described in Airbus A318/A319/A320/A321 ALS Part 5, Fuel Airworthiness Limitations, Revision 01, dated July 9, 2014. The initial compliance times for the tasks are at the times specified in Airbus A318/A319/A320/A321 ALS Part 5, Fuel Airworthiness Limitations, Revision 01, dated July 9, 2014, or within 60 days after the effective date of this AD, whichever occurs later. Incorporating the requirements of this paragraph terminates the requirements of paragraphs (g) through (k) of this AD.

(m) New Requirement of This AD: No Alternative Actions, Intervals, or CDCCLs

After the maintenance or inspection program has been revised as required by paragraph (l) of this AD, no alternative actions (e.g., inspections), intervals, or CDCCLs may be used unless the actions, intervals, or CDCCLs are approved as an AMOC in accordance with the procedures specified in paragraph (n)(1) of this AD.
