Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2012-20-
07, for certain Airbus Model A318, A319, A320, and A321 series 
airplanes. AD 2012-20-07 currently requires 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. Since we issued AD 2012-20-07, 
Airbus has issued more restrictive maintenance requirements and/or 
airworthiness limitations. This proposed AD would require revising the 
maintenance or inspection program to incorporate revised fuel 
airworthiness limitations. We are proposing 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: We must receive comments on this proposed AD by May 31, 2016.

Discussion

    On October 2, 2012, we issued AD 2012-20-07, Amendment 39-17213 (77 
FR 63716, October 17, 2012) (``AD 2012-20-07''). AD 2012-20-07 requires 
actions intended to address an unsafe condition on all Model A319, 
A320, and A321 series airplanes.
    Since we issued AD 2012-20-07, Airbus has issued A318/A319/A320/
A321 Airworthiness Limitations Section (ALS) Part 5, Fuel Airworthiness 
Limitations, Revision 01, dated July 9, 2014, which contains more 
restrictive maintenance requirements and/or airworthiness limitations. 
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 [http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgFAR.nsf/0/EEFB3F94451DC06286256C93004F5E07?OpenDocument&Highlight=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 (http://ad.easa.europa.eu/

[[Page 22034]]

blob/easa_ad_2011_0155_R1_superseded.pdf/AD_2011-0155R1_1), which is 
superseded [and which corresponds to FAA AD 2012-20-07, Amendment 
39-17213 (77 FR 63716, October 17, 2012)], 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.

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.

FAA's Determination and Requirements of [hairsp]This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.
    This proposed AD requires revisions to certain operator maintenance 
documents to include new actions (e.g., inspections) and/or Critical 
Design Configuration Control Limitations (CDCCLs). Compliance with 
these actions and/or 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 
(n)(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.
    Notwithstanding any other maintenance or operational requirements, 
components that have been identified as airworthy or installed on the 
affected airplanes before accomplishing the revision of the airplane 
maintenance or inspection program or before accomplishing the revision 
of the Airworthiness Limitation Section (ALS) of the Instructions for 
Continued Airworthiness specified in this proposed AD, do not need to 
be reworked in accordance with the CDCCLs. However, once the airplane 
maintenance or inspection program or ALS has been revised as required 
by this proposed AD, future maintenance actions on these components 
must be done in accordance with the CDCCLs.

Differences Between This Proposed AD and the MCAI or Service 
Information

    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.

Explanation of Proposed Compliance Time

    In most ADs, we adopt a compliance time allowing a specified amount 
of time after the AD's effective date or as specified by the MCAI, 
whichever is later. In this case, however, the MCAI compliance time has 
already expired. We have determined that an appropriate initial 
compliance time is 60 days for revising the maintenance or inspection 
program to incorporate 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. We find 60 days an 
appropriate compliance time to revise the maintenance or inspection 
program. 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, 
whichever is later. In developing the compliance time for this action, 
we considered the degree of urgency associated with addressing the 
unsafe condition. This difference has been coordinated with the EASA.

Airworthiness Limitations Based on Type Design

    The FAA recently became aware of an issue related to the 
applicability of ADs that require incorporation of an ALS revision into 
an operator's maintenance or inspection program.
    Typically, when these types of ADs are issued by civil aviation 
authorities of other countries, they apply to all airplanes covered 
under an identified type certificate (TC). The corresponding FAA AD 
typically retains applicability to all of those airplanes.
    In addition, U.S. operators must operate their airplanes in an 
airworthy condition, in accordance with 14 CFR 91.7(a). Included in 
this obligation is the requirement to perform any maintenance or 
inspections specified in the ALS, and in accordance with the ALS as 
specified in 14 CFR 43.16 and 91.403(c), unless an alternative has been 
approved by the FAA.
    When a type certificate is issued for a type design, the specific 
ALS, including revisions, is a part of that type design, as specified 
in 14 CFR 21.31(c).
    The sum effect of these operational and maintenance requirements is 
an obligation to comply with the ALS defined in the type design 
referenced in the manufacturer's conformity statement. This obligation 
may introduce a conflict with an AD that requires a specific ALS 
revision if new airplanes are delivered with a later revision as part 
of their type design.
    To address this conflict, the FAA has approved alternative methods 
of compliance (AMOCs) that allow operators to incorporate the most 
recent ALS revision into their maintenance/inspection programs, in lieu 
of the ALS revision required by the AD. This eliminates the conflict 
and enables the operator to comply with both the AD and the type 
design.
    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

[[Page 22035]]

of the type design or as mandated by an earlier AD.
    This proposed AD therefore applies to the airplanes identified in 
paragraph (c) of this proposed AD 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.

Record of Ex Parte Communication

    In preparation of AD actions, it is the practice of the FAA to 
obtain technical information and information on the operational and 
economic impact from design approval holders and aircraft operators. We 
discussed certain issues related to this NPRM in a recent meeting with 
Airlines for America (A4A). Shortly after this NPRM is published, we 
will post a summary of this meeting in the rulemaking docket. For 
information on locating the docket, see ``Examining the AD Docket.''

Costs of Compliance

    We estimate that this proposed AD affects 953 airplanes of U.S. 
registry.
    The actions required by AD 2012-20-07, and retained in this 
proposed 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 proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2012-20-07, Amendment 39-17213 (77 FR 63716, October 17, 2012), and 
adding the following new AD:
