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.

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.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of 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-

[[Page 72509]]

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.

(k) Retained Requirement: No Alternative Actions, Intervals, and/or 
CDCCLs, With No Changes

    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.
