Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus Model A310 series airplanes. This proposed AD was prompted by a 
revision of certain airworthiness limitation items (ALI) documents, 
which require more restrictive maintenance requirements and 
airworthiness limitations. This proposed AD would require revising the 
maintenance or inspection program to incorporate the maintenance 
requirements and airworthiness limitations. We are proposing this AD to 
address the unsafe condition on these products.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2016-0217, dated November 2, 2016 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model A310 
series airplanes. The MCAI states:

    The airworthiness limitations for Airbus A310 aeroplanes, which 
are approved by EASA, are currently defined and published in the 
Airbus A310 Airworthiness Limitations Section (ALS) document(s). 
These instructions have been identified as mandatory actions for 
continued airworthiness.
    Failure to accomplish these instructions could result in an 
unsafe condition.
    EASA previously issued [EASA] AD 2014-0124 (later revised) 
[which includes actions for Airbus A310 series airplanes; those 
actions are included in FAA AD 2013-13-13, Amendment 39-17501 (79 FR 
48957, August 19, 2014) (``AD 2013-13-13'')], to require the actions 
as specified in Airbus A310 Airworthiness Limitation Item (ALI) 
Document at issue 08.
    Since EASA AD 2014-0124R1 was issued, Airbus replaced ALI 
Document issue 08 with A310 ALS Part 2 Revision 01 and then 
published the A310 ALS Part 2 Variation 1.1 and Variation 1.2, to 
introduce more restrictive maintenance requirements and/or 
airworthiness limitations.
    For the reason described above, this [EASA] AD retains part of 
the requirements of EASA AD 2014-0124R1, which will be superseded, 
and requires accomplishment of the actions specified in Airbus A310 
ALS Part 2 Revision 01, ALS Part 2 Variation 1.1 and ALS Part 2 
Variation 1.2 (hereafter collectively referred to as `the ALS' in 
this [EASA] AD). The remaining requirements of EASA AD 2014-0124R1 
are retained in [EASA] AD 2016-0218, applicable to A300-600 
aeroplanes, published at the same time as this [EASA] AD.

    This NPRM would not supersede AD 2013-13-13. 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 maintenance 
requirements and airworthiness limitations. Accomplishment of the 
proposed actions would then terminate all requirements of AD 2013-13-
13.
    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-2017-
0628.

Related Service Information Under 1 CFR Part 51

    We reviewed the following service information:
     Airbus A310 Airworthiness Limitations Section (ALS), Part 
2, ``Damage Tolerant Airworthiness Limitation Items (DT--ALI),'' 
Revision 01, dated August 7, 2015.
     Airbus A310 Airworthiness Limitations Section (ALS), Part 
2, ``Damage Tolerant Airworthiness Limitation Items (DT--ALI),'' 
Variation 1.1, dated January 25, 2016.
     Airbus A310 Airworthiness Limitations Section (ALS), Part 
2, ``Damage Tolerant Airworthiness Limitation Items (DT--ALI),'' 
Variation 1.2, dated July 22, 2016.
    The service information describes airworthiness limitations 
applicable to the DT--ALIs. These documents are distinct because they 
contain different tasks at different revision levels. 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 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 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 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

[[Page 29791]]

actions that will ensure the continued damage tolerance of the affected 
structure.

Costs of Compliance

    We estimate that this proposed AD affects 8 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

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.
