SUMMARY: We are superseding Airworthiness Directive (AD) 2014-26-53 and 
AD 2015-03-02 for certain Airbus Model A319-115, A319-133, A320-214, 
A320-232, and A320-233 airplanes. AD 2014-26-53 required repetitive 
detailed visual inspections to detect discrepancies of the wing lower 
skin surface and inboard main landing gear (MLG) support rib lower 
flange location fasteners and, depending on findings, accomplishment of 
applicable corrective action(s). AD 2015-03-02 required repetitive 
detailed visual inspections of the outboard MLG support rib lower 
flange fasteners for discrepancies, and corrective actions if 
necessary. This new AD retains the repetitive detailed visual 
inspections to detect discrepancies of the fasteners located in the 
wing lower skin surface and inboard MLG support rib lower flange with 
extended compliance times and repetitive intervals, and accomplishment 
of applicable corrective actions. This new AD also retains the 
repetitive detailed visual inspections of the outboard MLG support rib 
lower flange fasteners for discrepancies, and corrective actions if 
necessary. In addition, this new AD adds airplanes to the 
applicability. This AD was prompted by a determination that certain 
airplanes were missing from the applicability of AD 2014-26-53 and AD 
2015-03-02 and that those airplanes may be affected by the unsafe 
condition addressed in AD 2014-26-53 and AD 2015-03-02. We are issuing 
this AD to detect and correct discrepancies of the fasteners at the 
external surface of the lower wing skin and inboard and outboard MLG 
support rib lower flanges, which could result in an airplane not 
meeting its maximum loads expected in service. This condition could 
result in structural failure.

DATES: This AD becomes effective May 12, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 12, 
2015.

SUPPLEMENTARY INFORMATION: 

Discussion

    On January 7, 2015, we issued AD 2014-26-53, Amendment 39-18068 (80 
FR 3155, January 22, 2015). AD 2014-26-53 applied to certain Airbus 
Model A319-115, A319-133, A320-214, A320-232, and A320-233 airplanes. 
AD 2014-26-53 was prompted by reports of failure of certain fasteners 
located at the wing lower skin surface and inboard MLG support rib 
lower flange. AD 2014-26-53 required repetitive detailed visual 
inspections to detect discrepancies of the wing lower skin surface and 
inboard MLG support rib lower flange location fasteners and, depending 
on findings, accomplishment of applicable corrective action(s). We 
issued AD 2014-26-53 to detect and correct discrepancies of the 
fasteners at the external surface of the lower wing skin and inboard 
MLG support rib lower flange, which could result in an airplane not 
meeting its maximum loads expected in service. This condition could 
result in structural failure.
    On January 30, 2015, we issued AD 2015-03-02, Amendment 39-18098 
(80 FR 6897, February 9, 2015). AD 2015-03-02 applied to certain Airbus 
Model A319-115, A319-133, A320-214, A320-232, and A320-233 airplanes. 
AD 2015-03-02 was prompted by reports of failure of certain fasteners 
on the MLG support rib lower flange. AD 2015-03-02 required repetitive 
detailed visual inspections of the outboard MLG support rib lower 
flange fasteners for discrepancies, and corrective actions if 
necessary. We issued AD 2015-03-02 to detect and correct discrepancies 
of the fasteners at the outboard MLG support rib lower flange, which 
could result in an airplane not meeting its maximum loads expected in 
service. This condition could result in structural failure.
    Since we issued AD 2014-26-53, Amendment 39-18068 (80 FR 3155, 
January 22, 2015); and AD 2015-03-02, Amendment 39-18098 (80 FR 6897, 
February 9, 2015); we have determined that certain airplanes were 
missing from the applicability of AD 2014-26-53 and AD 2015-03-02. 
Airbus Model A319-132 airplanes are affected with the identified unsafe 
condition and should have been included in the applicability of those 
ADs. In addition, we have also determined that the repetitive detailed 
visual inspections to detect discrepancies of the wing lower skin 
surface and inboard MLG support rib lower flange could be extended from 
8-day intervals to 60-day intervals.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2015-0026, dated February 19, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A319-115, A319-132, A319-133, A320-214, A320-232, and A320-233 
airplanes. The MCAI states:

    During production of wings, a number of taperlok fasteners were 
found failed after installation. The fasteners in question are 
located at the bottom skin of the Main Landing Gear (MLG) 
reinforcing plate, wing skin and Gear Support Rib 5 lower flange. 
Based on the results of the preliminary investigation, this affects 
only certain A319

[[Page 23234]]

and A320 aeroplanes delivered since January 2014.
    This condition, if not detected and corrected could reduce the 
design safety margin of the structure.
    Prompted by these findings, EASA issued Emergency AD 2014-0270-E 
(later revised) [which corresponds to certain requirements of AD 
2014-26-53, Amendment 39-18068 (80 FR 3155, January 22, 2015)] to 
require repetitive detailed inspections (DET) of the bottom skin 
taperlok fasteners at the MLG Rib 5 footprint location and, 
depending on findings, accomplishment of applicable corrective 
action(s).
    Since EASA AD 2014-0270R1 [which corresponds to certain 
requirements of AD 2015-03-02, Amendment 39-18098 (80 FR 6897, 
February 19, 2015)] was issued, based on in service feedback and 
further investigation, Airbus issued Revision 01 of Alert Operators 
Transmission (AOT) A57N006-14 to extend the original 8 calendar days 
inspection interval to 60 calendar days for the external area and 
for the internal inboard side. In addition, it was identified that 
the model A319-132 was missing from the [EASA] AD applicability.
    For the reasons described above, this AD retains the 
requirements of EASA AD 2014-0270R1, which is superseded, to amend 
the Applicability and to require those actions within the new 
thresholds and intervals.
    This [EASA] AD is still considered to be an interim action and 
further [EASA] AD action may follow.

    You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-
0930.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Airbus Alert Operators Transmission (AOT) 
A57N006-14, Revision 01, dated February 16, 2015. The service 
information describes procedures for repetitive detailed visual 
inspections to detect discrepancies of the wing lower skin surface and 
inboard and outboard MLG support rib lower flange location fasteners 
and corrective actions. The actions described in this service 
information are intended to correct the unsafe condition identified in 
the MCAI.
    This service information is reasonably available at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-
0930. Or see ADDRESSES for other ways to access this service 
information.

FAA's Determination and Requirements of This 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 issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
failure of more than two fasteners at the outboard MLG support rib 
lower flange could result in an airplane not meeting its maximum loads 
expected in-service. This condition could result in failure of the 
structure. Therefore, we determined that notice and opportunity for 
public comment before issuing this AD are impracticable and that good 
cause exists for making this amendment effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2015-0930; Directorate 
Identifier 2015-NM-040-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 148 airplanes of U.S. registry.
    The actions required by AD 2014-26-53, Amendment 39-18068 (80 FR 
3155, January 22, 2015); and AD 2015-03-2, Amendment 39-18098 (80 FR 
6897, February 9, 2015); and retained in this 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 were required 
by AD 2014-26-53 and AD 2015-03-06 is $170 per product, per inspection 
cycle.
    We also estimate that it will take about 2 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $25,160, or $170 per product, per 
inspection cycle.
    In addition, we estimate that any fastener replacement will take 
about 3 work-hours and require parts costing $400, for a cost of $655 
per fastener replacement. 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.

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will 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 that this AD:
    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.

5855, 5864, 5875, 5886, 5896, 5910, and 5918 and subsequent.

(d) Subject

    Air Transport Association (ATA) of America Code 57, Wings.

(e) Reason

    This AD was prompted by a determination that certain airplanes 
were not included in the applicability of AD 2014-26-53, Amendment 
39-18068 (80 FR 3155, January 22, 2015); and AD 2015-03-02, 
Amendment 39-18098 (80 FR 6897, February 9, 2015). This AD was also 
prompted by reports of failure of certain fasteners located at the 
wing lower skin surface, and inboard and outboard main landing gear 
(MLG) support rib lower flanges. We are issuing this AD to detect 
and correct discrepancies of the fasteners at the external surface 
of the lower wing skin and inboard and outboard MLG support rib
