SUPPLEMENTARY INFORMATION: Discussion On December 16, 2014, we issued Emergency AD 2014–26–53, which requires 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). Corrective actions include fastener replacement or repair. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued Airworthiness Directive 2014–0270R1, dated December 15, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition on certain Airbus Model A319–115, A319–133, A320–214, A320–232, and A320–233 airplanes. The MCAI states: tkelley on DSK3SPTVN1PROD with RULES 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. This condition, if not detected and corrected could reduce the design margin of the structure [and could result in structural failure]. Based on the results of the preliminary investigation, this affects only certain A319 VerDate Sep<11>2014 16:25 Jan 21, 2015 Jkt 235001 and A320 aeroplane Models delivered since January 2014. A321 aeroplanes are not affected, as the wing assembly is done using parallel fasteners. A318 aeroplanes are not affected, since none have been delivered since January 2014. Prompted by these findings, EASA issued Emergency AD 2014–0270–E [dated December 11, 2014] to require repetitive inspections of the bottom skin taperlok fasteners at the MLG Rib 5 footprint location and, depending on findings, accomplishment of applicable corrective action(s). Since that AD was issued, operator comments have indicated the need for clarification, as well as correction. For the reason described above, this [EASA] AD is revised to add Notes for information and to correct paragraphs (1) and (2) of the AD. This [EASA] AD is still considered to be an interim action and further AD action may follow. Related Service Information Airbus has issued Airbus Alert Operators Transmission (AOT) A57N006–14, Revision 00, dated December 4, 2014. The service information describes procedures for inspections of the bottom skin fasteners at the MLG rib 5 footprint location, and replacement of affected fasteners. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. You can find this information at http://www.regulations.gov by searching for and locating Docket No. FAA–2014– 0927. FAA’s Determination and AD Requirements 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 the same type design. Differences Between This AD and the MCAI or Service Information EASA Airworthiness Directive 2014– 0270–E, dated December 11, 2014, specifies to do repetitive detailed visual inspections of the outboard MLG support rib lower flange fasteners and PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 nuts. However, these inspections are not required by this AD. Since the specified compliance time is four months, we are considering further rulemaking to require those inspections. 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 discrepancies of the fasteners at the external surface of the lower wing skin and inboard MLG support rib lower flange could result in an airplane not meeting its maximum loads expected in-service. This condition could result in structural failure. Therefore, we find that notice and opportunity for prior public comment are impracticable and that good cause exists for making this amendment effective in less than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety and was not preceded by notice and an opportunity for public comment. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include the docket number FAA–2014–0927 and Directorate Identifier 2014–NM–230–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 80 airplanes of U.S. registry. We estimate the following costs to comply with this AD: E:\FR\FM\22JAR1.SGM 22JAR1 Federal Register / Vol. 80, No. 14 / Thursday, January 22, 2015 / Rules and Regulations 3157 ESTIMATED COSTS Action Labor cost Parts cost Inspection ...................... 1 work-hour × $85 per hour = $85 [per inspection cycle]. $0 We estimate the following costs to do any necessary replacements that would Cost per product $85 [per inspection cycle]. be required based on the results of the inspection. We have no way of Cost on U.S. operators $6,800 [per inspection cycle]. determining the number of aircraft that might need these replacements: ON-CONDITION COSTS Action Labor cost Parts cost Cost per product Replacement ........................ 3 work-hours × $85 per hour = $255 [per fastener replacement]. $400 [per fastener] ............ $655 [per fastener replacement]. We have received no definitive data that would enable us to provide cost estimates for the on-condition repairs 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. tkelley on DSK3SPTVN1PROD with RULES Regulatory Findings 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 DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), (3) Will not affect intrastate aviation in Alaska, and VerDate Sep<11>2014 16:25 Jan 21, 2015 Jkt 235001 (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.

Discussion

    On December 16, 2014, we issued Emergency AD 2014-26-53, which 
requires 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). Corrective actions include fastener 
replacement or repair. This emergency AD was sent previously to all 
known U.S. owners and operators of these airplanes.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued 
Airworthiness Directive 2014-0270R1, dated December 15, 2014 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition on certain Airbus Model 
A319-115, 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.
    This condition, if not detected and corrected could reduce the 
design margin of the structure [and could result in structural 
failure].
    Based on the results of the preliminary investigation, this 
affects only certain A319 and A320 aeroplane Models delivered since 
January 2014. A321 aeroplanes are not affected, as the wing assembly 
is done using parallel fasteners. A318 aeroplanes are not affected, 
since none have been delivered since January 2014.
    Prompted by these findings, EASA issued Emergency AD 2014-0270-E 
[dated December 11, 2014] to require repetitive inspections of the 
bottom skin taperlok fasteners at the MLG Rib 5 footprint location 
and, depending on findings, accomplishment of applicable corrective 
action(s).
    Since that AD was issued, operator comments have indicated the 
need for clarification, as well as correction.
    For the reason described above, this [EASA] AD is revised to add 
Notes for information and to correct paragraphs (1) and (2) of the 
AD.
    This [EASA] AD is still considered to be an interim action and 
further AD action may follow.

Related Service Information

    Airbus has issued Airbus Alert Operators Transmission (AOT) 
A57N006-14, Revision 00, dated December 4, 2014. The service 
information describes procedures for inspections of the bottom skin 
fasteners at the MLG rib 5 footprint location, and replacement of 
affected fasteners. The actions described in this service information 
are intended to correct the unsafe condition identified in the MCAI. 
You can find this information at http://www.regulations.gov by 
searching for and locating Docket No. FAA-2014-0927.

FAA's Determination and AD Requirements

    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 the same 
type design.

Differences Between This AD and the MCAI or Service Information

    EASA Airworthiness Directive 2014-0270-E, dated December 11, 2014, 
specifies to do repetitive detailed visual inspections of the outboard 
MLG support rib lower flange fasteners and nuts. However, these 
inspections are not required by this AD. Since the specified compliance 
time is four months, we are considering further rulemaking to require 
those inspections.

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 
discrepancies of the fasteners at the external surface of the lower 
wing skin and inboard MLG support rib lower flange could result in an 
airplane not meeting its maximum loads expected in-service. This 
condition could result in structural failure. Therefore, we find that 
notice and opportunity for prior public comment are impracticable and 
that good cause exists for making this amendment effective in less than 
30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include the docket number FAA-2014-0927 and 
Directorate Identifier 2014-NM-230-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 80 airplanes of U.S. registry.
    We estimate the following costs to comply with 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

    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 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.
