Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2015-05-
02, for certain Airbus Model A318, A319, A320, and A321 series 
airplanes. AD 2015-05-02 requires revising the maintenance or 
inspection program to incorporate new, more restrictive airworthiness 
limitations. Since we issued AD 2015-05-02, an evaluation by the design 
approval holder (DAH) indicates that principal structural elements and 
certain life limited parts are subject to widespread fatigue damage 
(WFD). This proposed AD would require revising the maintenance or 
inspection program, as applicable, to incorporate new or revised 
structural inspection requirements. We are proposing this AD to prevent 
fatigue cracking, accidental damage, or corrosion in principal 
structural elements, and WFD, which could result in reduced structural 
integrity of the airplane.

DATES: We must receive comments on this proposed AD by June 27, 2016.

Discussion

    Structural fatigue damage is progressive. It begins as minute 
cracks, and those cracks grow under the action of repeated stresses. 
This can happen because of normal operational conditions and design 
attributes, or because of isolated situations or incidents such as 
material defects, poor fabrication quality, or corrosion pits, dings, 
or scratches. Fatigue damage can occur locally, in small areas or 
structural design details, or globally. Global fatigue damage is 
general degradation of large areas of structure with similar structural 
details and stress levels. Multiple-site damage is global damage that 
occurs in a large structural element such as a single rivet line of a 
lap splice joining two large skin panels. Global damage can also occur 
in multiple elements such as adjacent frames or stringers. Multiple-
site-damage and multiple-element-damage cracks are typically too small 
initially to be reliably detected with normal inspection methods. 
Without intervention, these cracks will grow, and eventually compromise 
the structural integrity of the airplane, in a condition known as 
widespread fatigue damage (WFD). As an airplane ages, WFD will likely 
occur, and will certainly occur if the airplane is operated long enough 
without any intervention.
    The FAA's WFD final rule (75 FR 69746, November 15, 2010) became 
effective on January 14, 2011. The WFD rule requires certain actions to 
prevent structural failure due to WFD throughout the operational life 
of certain existing transport category airplanes and all of these 
airplanes that will be certificated in the future. For existing and 
future airplanes subject to the WFD rule, the rule requires that DAHs 
establish a limit of validity (LOV) of the engineering data that 
support the structural maintenance program. Operators affected by the 
WFD rule may not fly an airplane beyond its LOV, unless an extended LOV 
is approved.
    The WFD rule (75 FR 69746, November 15, 2010) does not require 
identifying and developing maintenance actions if the DAHs can show 
that such actions are not necessary to prevent WFD before the airplane 
reaches the LOV. Many LOVs, however, do depend on accomplishment of 
future maintenance actions. As stated in the WFD rule, any maintenance 
actions necessary to reach the LOV will be mandated by airworthiness 
directives through separate rulemaking actions.
    In the context of WFD, this action is necessary to enable DAHs to 
propose LOVs that allow operators the longest operational lives for 
their airplanes, and still ensure that WFD will not occur. This 
approach allows for an implementation strategy that provides 
flexibility to DAHs in determining the timing of service information 
development (with FAA approval), while providing operators with 
certainty regarding the LOV applicable to their airplanes.
    On February 25, 2015, we issued AD 2015-05-02, Amendment 39-18112 
(80 FR 15152, March 23, 2015) (``AD 2015-05-02'') to supersede AD 2014-
23-15, Amendment 39-18031 (80 FR 3871, January 26, 2015). AD 2015-05-02 
requires revising the maintenance or inspection program, as applicable, 
to incorporate new, more restrictive airworthiness limitations on all 
Airbus Model A318, A319, A320, and A321 series airplanes.
    Since we issued AD 2015-05-02, an evaluation by the DAH indicates 
that principal structural elements and certain life limited parts are 
subject to widespread fatigue damage WFD. This proposed AD would 
require revising the maintenance or inspection program, as applicable, 
to incorporate new or revised structural inspection requirements.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2015-0083, dated May 12, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition.
    The MCAI states:

    The airworthiness limitations for Airbus A320 family aeroplanes 
are currently included in Airbus A318/A319/A320/A321 Airworthiness 
Limitations Section (hereafter referred to as `ALS') documents. The 
Damage Tolerant airworthiness limitation items are published in ALS 
Part 2, approved by EASA.
    The instructions contained in the ALS Part 2 have been 
identified as mandatory actions for continued airworthiness. Failure 
to comply with these instructions could result in an unsafe 
condition.
    Previously, EASA issued AD 2013-0147 (http://ad.easa.europa.eu/blob/easa_ad_2013_0147_superseded.pdf/AD_2013-0147_1) [which 
corresponds to FAA AD 2014-23-15, Amendment 39-18031 (80 FR 3871, 
January 26, 2015) to require accomplishment of all maintenance tasks 
as described in ALS Part 2 at Revision 02. The new ALS Part 2 
Revision 03 [Issue October 27, 2014] includes new and/or more 
restrictive items and was approved on 27 October 2014.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2013-0147, which is superseded, and requires 
accomplishment of all maintenance tasks as described in ALS Part 2 
at Revision 03.

    The required action is revising the maintenance or inspection 
program to incorporate new or revised structural inspection 
requirements. The unsafe condition is fatigue cracking, accidental 
damage, or corrosion in principal structural elements, and WFD, which 
could result in reduced structural integrity of the airplane. 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-
6429.

Other Relevant Rulemaking

    We have issued NPRM Docket FAA-2015-6539, Directorate Identifier 
2015-NM-036-AD (80 FR 74723, November 30, 2015), for all Airbus Model 
A318-111 and -112 airplanes; Model A319-111, -112, -113, -114, and -115 
airplanes; Model A320-211, -212, and -214 airplanes; and Model A321-
111, -112, -211, -212, and -213 airplanes. That NPRM proposes to 
require repetitive inspections that reduce the compliance time for Task 
712111-01, Detailed Inspection of Forward Engine Mount Installation. 
Therefore, Task 712111-01 is not included in this proposed AD.

Related Service Information Under 1 CFR Part 51

business or by the means identified in the ADDRESSES section.

FAA's Determination and Requirements of 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 these 
same type designs.
    This proposed AD requires revisions to certain operator maintenance 
documents to include new actions (e.g., inspections). Compliance with 
these actions 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 might 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 (AMOC) in accordance with the provisions of 
paragraph (k)(1) of this proposed AD. The request should include a 
description of changes to the required actions that will ensure the 
continued damage tolerance of the affected structure.

Differences Between This Proposed AD and the MCAI or Service 
Information

    This proposed AD differs from the MCAI in that it specifies 
revising the maintenance or inspection program, as applicable, to 
incorporate the ALIs specified in Airbus A318/A319/A320/A321 ALS Part 
2, Damage Tolerant Airworthiness Limitation Items (DT-ALI), Revision 
04, dated December 18, 2015; and Airbus A318/A319/A320/A321 ALS Part 2, 
Damage Tolerant Airworthiness Limitation Items (DT-ALI), Variation 4.2, 
dated January 15, 2016. The MCAI specifies incorporating the ALIs 
specified in Airbus A318/A319/A320/A321 ALS Safe Life Airworthiness 
Limitation Section (ALS), Part 2, Damage Tolerant Airworthiness 
Limitation Items (DT-ALI), Revision 03, Issue October 27, 2014. We have 
coordinated this change with EASA.
    EASA has issued EASA Proposed Airworthiness Directive (PAD) 16-029, 
dated February 24, 2016, which specifies incorporating the ALI's in 
Airbus A318/A319/A320/A321 ALS Part 2, Damage Tolerant Airworthiness 
Limitation Items (DT-ALI), Revision 04, dated December 18, 2015; and 
Airbus A318/A319/A320/A321 ALS Part 2, Damage Tolerant Airworthiness 
Limitation Items (DT-ALI), Variation 4.2, dated January 15, 2016.
    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.

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 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 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 959 airplanes of U.S. 
registry.
    The actions required by AD 2015-05-02, and retained in this 
proposed AD take about 2 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

[[Page 29201]]

required by AD 2015-05-02 is $170 per product.
    We also estimate that it would take about 2 work-hours 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 $163,030, or $170 
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.
