We are revising an earlier proposed airworthiness directive (AD) to supersede Airworthiness Directive (AD) 2010-04-03, for all Airbus Model A310 series airplanes. AD 2010-04-03 currently requires accomplishing repetitive detailed inspections for cracking around the fastener holes in certain wing top skin panels between the front and rear spars on the left- and right-hand sides of the fuselage, and repair if necessary. The NPRM proposed to continue to require the repetitive detailed inspections, and would also require supplemental repetitive ultrasonic inspections for cracking around the fastener holes in wing top skin panels 1 and 2 at rib 2, and repair if necessary. This action revises the NPRM by expanding the inspection area to include rib 3 due to widespread fatigue damage. We are proposing this supplemental NPRM (SNPRM) to detect and correct fatigue cracking around the fastener holes, which could result in reduced structural integrity of the airplane. Since these actions impose an additional burden over those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of 
comment period.

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

SUMMARY: We are revising an earlier proposed airworthiness directive 
(AD) to supersede Airworthiness Directive (AD) 2010-04-03, for all 
Airbus Model A310 series airplanes. AD 2010-04-03 currently requires 
accomplishing repetitive detailed inspections for cracking around the 
fastener holes in certain wing top skin panels between the front and 
rear spars on the left- and right-hand sides of the fuselage, and 
repair if necessary. The NPRM proposed to continue to require the 
repetitive detailed inspections, and would also require supplemental 
repetitive ultrasonic inspections for cracking around the fastener 
holes in wing top skin panels 1 and 2 at rib 2, and repair if 
necessary. This action revises the NPRM by expanding the inspection 
area to include rib 3 due to widespread fatigue damage. We are 
proposing this supplemental NPRM (SNPRM) to detect and correct fatigue 
cracking around the fastener holes, which could result in reduced 
structural integrity of the airplane. Since these actions impose an 
additional burden over those proposed in the NPRM, we are reopening the 
comment period to allow the public the chance to comment on these 
proposed changes.

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2010-04-03, Amendment 39-16196 (75 FR 6852, 
February 12, 2010) (``AD 2010-04-03''). AD 2010-04-03 applied to all 
Airbus Model A310 series airplanes. The NPRM published in the Federal 
Register on October 13, 2015 (80 FR 61327) (``the NPRM''). The NPRM was 
prompted by development of an ultrasonic inspection program to allow 
for earlier crack detection and extend the repetitive inspection 
intervals. The NPRM proposed to retain the requirements of AD 2010-04-
03, and proposed to require supplemental repetitive ultrasonic 
inspections for cracking around the fastener holes in wing top skin 
panels 1 and 2 at rib 2, and repair if necessary.
    Since we issued the NPRM, a widespread fatigue damage analysis 
determined that the inspection area should be expanded to include 
cracking around the fastener holes in wing top skin panels 1 and 2 
between the front and rear spar at rib 3.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2016-0005, dated January 7, 2016 (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] AD 
2008-0211 [http://ad.easa.europa.eu/ad/2008-0211, which corresponds 
to FAA AD 2010-04-03] to require implementation of this inspection 
programme.
    After 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.
    Consequently, EASA issued and AD 2014-0200 (later revised), 
superseding [EASA] AD 2008-0211, retaining its requirements, and to 
require 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].
    Since EASA AD 2014-0020R1 was issued, a widespread fatigue 
damage analysis concluded that the inspection programme has to be 
extended to include the wing top skin panels at Rib 3 attachments. 
For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2014-0200R1, which is superseded, and 
extends the inspection area to include Rib 3.

    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 Service Bulletin A310-57-2096, Revision 03, dated 
June 30, 2015. This service information describes procedures for 
detailed and ultrasonic inspections for cracking around the fastener 
holes of wing top skin panels 1 and 2, at ribs 2 and 3, on the left- 
and right-hand sides of the fuselage. 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.

Comments

    We gave the public the opportunity to participate in developing 
this proposed AD. We considered the comment received. The commenter, 
FedEx, supported the content of the NPRM and is currently complying 
with the requirements.

FAA's Determination and Requirements of This SNPRM

    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.
    Certain changes described above expand the scope of the NPRM. As a 
result, we have determined that it is necessary to reopen the comment 
period to provide additional opportunity for the public to comment on 
this SNPRM.

Costs of Compliance

    We estimate that this SNPRM affects 28 airplanes of U.S. registry.
    We also estimate that it would take about 8 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 $19,040, or $680 
per product.
    We estimate that it would take about 15 work-hours per product to 
do any necessary on-condition actions that would be required based on 
the results of the inspections. Required parts would cost about $10,000 
per product. We have no way of determining the number of aircraft that 
might need these actions.

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.

[[Page 44814]]

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.
