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 A300 and A310 series airplanes; Model A300 B4-600, B4-
600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F 
airplanes (collectively called Model A300-600 series airplanes). This 
proposed AD was prompted by a determination that new or more 
restrictive maintenance requirements and airworthiness limitations are 
necessary. This proposed AD would require revising the maintenance or 
inspection program, as applicable, to incorporate new or more 
restrictive maintenance requirements and airworthiness limitations. We 
are proposing this AD to address the unsafe condition on these 
products.

DATES: We must receive comments on this proposed AD by June 28, 2018.

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 2017-0204, dated October 12, 2017 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model A300 
and A310 series airplanes, and Model A300 B4-600, B4-600R, and F4-600R 
series airplanes, and Model A300 C4-605R Variant F airplanes 
(collectively called Model A300-600 series airplanes). The MCAI states:

    The airworthiness limitations for the Airbus A300, A310, A300-
600 and A300-

[[Page 22220]]

600ST family aeroplanes, which are approved by EASA, are currently 
defined and published in the Airbus A300, A310 and A300-600 
Airworthiness Limitations Section (ALS) documents. The Safe Life 
Airworthiness Limitation Items are specified in the A300, A310 and 
A300-600 (including the A300-600ST) ALS Part 1 documents. These 
instructions have been identified as mandatory for continuing 
airworthiness.
    Failure to accomplish these instructions could result in an 
unsafe condition.
    EASA previously issued AD 2013-0248 [which corresponds to FAA AD 
2015-22-05, Amendment 39-18310 (80 FR 69846, November 12, 2015) 
(``AD 2015-22-05'')] to require the implementation of the 
instructions and airworthiness limitations as specified in Airbus 
A300, A310 and A300-600 ALS Part 1 documents at Revision 01.
    Since that [EASA] AD was issued, improvement of safe life 
component selection and life extension campaigns resulted in life 
limitations changes, among others new or more restrictive life 
limitations, approved by EASA. Consequently, Airbus published 
Revision 02 of the A300, A310 and A300-600 ALS Part 1, compiling all 
ALS Part 1, compiling all ALS Part 1 changes approved since previous 
Revision 01.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2013-0248, which is superseded, and requires 
accomplishment of the actions specified in A300 ALS Part 1 Revision 
02, A310 ALS Part 1 Revision 02 and A300-600 ALS Part 1 Revision 02.

    This NPRM would require revising the maintenance or inspection 
program to incorporate certain maintenance requirements and 
airworthiness limitations. The unsafe condition is fatigue damage in 
principal structural elements, 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-2018-0364.

Relationship Between Proposed AD and AD 2015-22-05

    This NPRM would not supersede AD 2015-22-05. 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, as applicable, to incorporate 
maintenance requirements and/or airworthiness limitations that are 
newer or more restrictive than those required by AD 2015-22-05. 
Accomplishment of the proposed actions would then terminate all 
requirements of AD 2015-22-05.

Related Service Information Under 1 CFR Part 51

    Airbus has issued the following service information, which 
describes procedures for revising the maintenance or inspection program 
to incorporate new or more restrictive maintenance requirements and 
airworthiness limitations. These documents are distinct since they 
apply to different airplane models.
     For Model A300 series airplanes: Section 4, ``Life Limits 
(LL)/Demonstrated Fatigue Lives (DF),'' of Part 1, ``Safe Life 
Airworthiness Limitation Items (SL-ALI),'' Revision 02, dated August 
28, 2017, of the Airbus Model A300 Airworthiness Limitations Section 
(ALS).
     For Model A300 B4-600, B4-600R, and F4-600R series 
airplanes, and Model A300 C4-605R Variant F airplanes (collectively 
called Model A300-600 series airplanes): Section 4, ``Life Limits (LL)/
Demonstrated Fatigue Lives (DF),'' of Part 1, ``Safe Life Airworthiness 
Limitation Items (SL-ALI),'' Revision 02, dated August 28, 2017, of the 
Airbus Model A300-600 Airworthiness Limitations Section (ALS).
     For Model A310 series airplanes: Section 4, ``Life Limits 
(LL)/Demonstrated Fatigue Lives (DF),'' of Part 1, ``Safe Life 
Airworthiness Limitation Items (SL-ALI),'' Revision 02, dated August 
28, 2017, of the Airbus Model A310 Airworthiness Limitations Section 
(ALS).
    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 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 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 
actions that will ensure the continued damage tolerance of the affected 
structure.

Costs of Compliance

    We estimate that this proposed AD affects 132 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:
    We have determined that revising the maintenance or inspection 
program takes an average of 90 work-hours per operator, although we 
recognize that this number may vary from operator to operator. In the 
past, we have estimated that this action takes 1 work-hour per 
airplane. Since operators incorporate maintenance or inspection program 
changes for their affected fleet(s), we have determined that a per-
operator estimate is more accurate than a per-airplane estimate. 
Therefore, we estimate the total cost per operator to be $7,650 (90 
work-hours x $85 per work-hour).

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.
    This proposed AD is issued in accordance with authority delegated 
by the Executive Director, Aircraft Certification Service, as 
authorized by FAA Order 8000.51C. In accordance with that order, 
issuance of ADs is normally a function of the Compliance and 
Airworthiness Division, but during this transition period, the 
Executive Director has delegated the authority to issue ADs applicable 
to transport category airplanes to the Director of the System Oversight 
Division.

[[Page 22221]]

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.
