Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2010-04-
03, for all Airbus Model A310 series airplanes. AD 2010-04-03 currently 
requires accomplishing repetitive detailed visual inspections for 
cracking around the fastener holes in certain wing top skin panels 
between the right side and left side of the front and rear spars, and 
repair if needed. Since we issued AD 2010-04-03, Airbus improved the 
ultrasonic inspection program to allow earlier crack detection and to 
extend the repetitive inspection intervals. We have determined these 
inspections are necessary to address the unsafe condition. This 
proposed AD would continue to require the repetitive detailed 
inspections for cracking around the fastener holes in certain wing top 
skin panels between the front and rear spars, and repair if needed, and 
would require supplemental repetitive ultrasonic inspections for 
cracking around the fastener holes in certain wing top skin panels and 
repair if needed. We are proposing this AD to detect and correct 
cracking around the fastener holes in certain wing top skin panels 
between the right side and left side of the front and rear spars, which 
could result in reduced structural integrity of the airplane.

Discussion

    On January 28, 2010, we issued AD 2010-04-03, Amendment 39-16196 
(75 FR 6852, February 12, 2010). AD 2010-04-03 requires actions 
intended to address an unsafe condition on all Airbus Model A310 series 
airplanes.
    Since we issued AD 2010-04-03, Amendment 39-16196 (75 FR 6852, 
February 12, 2010), the manufacturer improved the ultrasonic inspection 
program to allow earlier crack detection and to extend the repetitive 
inspection intervals. We have determined these inspections are 
necessary to address the unsafe condition.
    The European Aviation Safety Agency, which is the Technical Agent 
for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2014-0200R1, dated September 19, 2014 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition on all Airbus Model A310 
series airplanes. The MCAI states:

    Following scheduled maintenance, cracks were found around the 
wing top skin panels fastener holes at Rib 2, between Stringer (STG) 
2 and STG14.
    This condition, if not detected and corrected, could affect the 
structural integrity of the aeroplane. The General Visual Inspection 
required by the existing applicable Airworthiness Limitation Items 
(ALI) tasks may not be adequate to detect these cracks.
    To address this issue, Airbus developed an inspection programme 
based on repetitive detailed inspections (DET) to ensure that any 
visible cracks in the wing top skin panels 1 and 2 along Rib 2 are 
detected in time and repaired appropriately. EASA issued [EASA]

[[Page 61328]]

AD 2008-0211 [http://ad.easa.europa.eu/ad/2008-0211] to require 
implementation of this inspection programme.
    Since that [EASA] AD was issued, Airbus improved the inspection 
programme with an ultrasonic inspection to allow earlier crack 
detection, to subsequently reduce the scope of potential repair 
action, and to extend the intervals of the repetitive inspections.
    For the reasons described above, this [EASA] AD [http://ad.easa.europa.eu/ad/2014-0200R1] retains the requirements of EASA 
AD 2008-0211, which is superseded, and requires supplementary 
repetitive ultrasonic inspections [for cracking] of the wing top 
skin panel 1 and 2 between STG2 and STG10 at Rib 2 [and repair if 
needed].

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-2015-
3985.

Related Service Information Under 1 CFR Part 51

    Airbus has issued the following service information:
     Airbus Service Bulletin A310-57-2096, dated May 6, 2008,
     Airbus Service Bulletin A310-57-2096, Revision 01, dated 
August 5, 2010.
     Airbus Service Bulletin A310-57-2096, Revision 02, dated 
March 5, 2014.

This service information describes procedures for detailed visual and 
ultrasonic inspections for cracking around the fastener holes of the 
wing top skin panels between the right side and left side of the front 
and rear spars at certain locations, and repair if needed. 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 of this NPRM.

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.

Explanation of ``RC'' Procedures and Tests in Service Information

    The FAA worked in conjunction with industry, under the 
Airworthiness Directive Implementation Aviation Rulemaking Committee 
(ARC), to enhance the AD system. One enhancement was a new process for 
annotating which procedures and tests in the service information are 
required for compliance with an AD. Differentiating these procedures 
and tests from other tasks in the service information is expected to 
improve an owner's/operator's understanding of crucial AD requirements 
and help provide consistent judgment in AD compliance. The procedures 
and tests identified as RC (required for compliance) in any service 
information have a direct effect on detecting, preventing, resolving, 
or eliminating an identified unsafe condition.
    As specified in a NOTE under the Accomplishment Instructions of the 
specified service information, procedures and tests that are identified 
as RC in any service information must be done to comply with the 
proposed AD. However, procedures and tests that are not identified as 
RC are recommended. Those procedures and tests that are not identified 
as RC may be deviated from using accepted methods in accordance with 
the operator's maintenance or inspection program without obtaining 
approval of an alternative method of compliance (AMOC), provided the 
procedures and tests identified as RC can be done and the airplane can 
be put back in a serviceable condition. Any substitutions or changes to 
procedures or tests identified as RC will require approval of an AMOC.

Costs of Compliance

    We estimate that this proposed AD affects 13 airplanes of U.S. 
registry.
    We also estimate that it would take about 5 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost $0 per 
product. Based on these figures, we estimate the cost of this proposed 
AD on U.S. operators to be $5,525, or $425 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this 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.

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
