Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0223, dated October 23, 2012 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Airbus identified a batch of special washers, Part Number (P/N) D5725260120000 and P/N D5725664320000, which were incorrectly manufactured and delivered as spares from the supplier between October 2006 and January 2010. As a result of these manufacturing defects, the affected washers differ geometrically from the design specifications. The results of further analyses on Airbus A318, A319, A320 and A321 aeroplanes demonstrate that the affected washers could be seated incorrectly when installed on aeroplanes, which could affect the main landing gear (MLG) retraction jack anchorage fitting bearing installation. This condition, if not detected and corrected, could lead to a local stress concentration which may reduce the fatigue life of the jack fitting, possibly reducing the structural integrity of the affected MLG. For the reasons described above, this [EASA] AD requires a one-time detailed visual inspection of the left-hand (LH) and right-hand (RH) MLG retraction jack anchorage fitting bearing assemblies to verify that the special washer is seated correctly and, depending on findings, the accomplishment of applicable [related investigative action and] corrective actions. The related investigative action is a detailed inspection of the jack anchorage fitting for damage, corrosion, cracks or other defects. Corrective actions include replacing the special washer with a new special washer and repairing the jack anchorage fitting if there are signs of damage, corrosion, or other defects. You may obtain further PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 39191 information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued Airbus Service Bulletin A320–57–1169, Revision 01, dated September 18, 2012, and the following tasks in Subject 57–26–13, Attachment—Main Landing Gear, of Chapter 57, Wings, of the Airbus A318/ A319/A320/A321 Aircraft Maintenance Manual (AMM), Revision 50, dated November 1, 2012. • Task 57–26–13–400–001–A, Installation of the Bearing Assembly of the Forward Pintle Pin. • Task 57–26–13–400–002–A, Installation of the Bearing Assembly of the MLG Actuator Attachment. • Task 57–26–13–400–004–A, Installation of the Bearing Seals of the MLG Actuator Bearing Assembly. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. 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. Differences Between This Proposed AD and the MCAI or Service Information Airbus Service Bulletin A320–57– 1169, Revision 01, dated September 18, 2012, specifies to contact the manufacturer for instructions on how to repair certain conditions, but this proposed AD would require repairing those conditions using a method approved by either the Manager, International Branch, ANM–116, Transport Airplane Directorate, FAA; or the EASA (or its delegated agent). Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 851 products of U.S. registry. We also estimate that it would take about 3 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 the proposed AD on U.S. operators to be E:\FR\FM\01JYP1.SGM 01JYP1 39192 Federal Register / Vol. 78, No. 126 / Monday, July 1, 2013 / Proposed Rules $217,005, or $255 per product. In addition, we estimate that any necessary follow-on actions would take about 15 work-hours, for a cost of $1,275 per product. We have received no definitive data that would enable us to provide part cost estimates for the on-condition actions specified in this proposed AD. We have no way of determining the number of products that may need these actions. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Authority for This Rulemaking PART 39—AIRWORTHINESS DIRECTIVES 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 PROPOSALS 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. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. VerDate Mar<15>2010 17:48 Jun 28, 2013 Jkt 229001 The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: 1.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede an existing airworthiness directive (AD) that applies to all The Boeing Company Model 737–100, –200, –200C, –300, –400, and –500 series airplanes. The existing AD currently requires repetitive SUMMARY: PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 39193 inspections for discrepancies of each carriage spindle of the outboard midflaps; repetitive gap checks of the inboard and outboard carriages of the outboard mid-flaps to detect fractured carriage spindles; measuring to ensure that any new or serviceable carriage spindle meets minimum allowable diameter measurements taken at three locations; repetitive inspections, measurements, and overhaul of the carriage spindles; replacement of any carriage spindle when it has reached its maximum life limit; and corrective actions if necessary. Since we issued that AD, we received a report of failure of both flap carriages. This proposed AD would require reducing the life limit of the carriages, reducing the repetitive interval for certain inspections and gap checks for certain carriages. This proposed AD would also add an option, for certain replacements, of doing an inspection, and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct cracked, corroded, or fractured carriage spindles, which could lead to severe flap asymmetry, and could result in reduced control or loss of controllability of the airplane. DATES: We must receive comments on this proposed AD by August 15, 2013.

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus Model A318, A319, A320, and A321 series airplanes. This proposed 
AD was prompted by a determination that certain special washers used in 
the retraction jack anchorage fitting bearing installation in the main 
landing gear (MLG) were incorrectly manufactured. This proposed AD 
would require an inspection of the left-hand (LH) and right-hand (RH) 
MLG retraction jack anchorage fitting bearing assemblies to verify that 
the special washer is seated correctly, and related investigative and 
corrective actions if necessary. We are proposing this AD to detect and 
correct

[[Page 39191]]

installation of incorrectly manufactured special washers, which could 
lead to a local stress concentration resulting in possible reduction of 
the fatigue life of the jack fitting, and consequent reduction of the 
structural integrity of the affected MLG.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0223, dated October 23, 2012 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Airbus identified a batch of special washers, Part Number (P/N) 
D5725260120000 and P/N D5725664320000, which were incorrectly 
manufactured and delivered as spares from the supplier between 
October 2006 and January 2010. As a result of these manufacturing 
defects, the affected washers differ geometrically from the design 
specifications. The results of further analyses on Airbus A318, 
A319, A320 and A321 aeroplanes demonstrate that the affected washers 
could be seated incorrectly when installed on aeroplanes, which 
could affect the main landing gear (MLG) retraction jack anchorage 
fitting bearing installation.
    This condition, if not detected and corrected, could lead to a 
local stress concentration which may reduce the fatigue life of the 
jack fitting, possibly reducing the structural integrity of the 
affected MLG.
    For the reasons described above, this [EASA] AD requires a one-
time detailed visual inspection of the left-hand (LH) and right-hand 
(RH) MLG retraction jack anchorage fitting bearing assemblies to 
verify that the special washer is seated correctly and, depending on 
findings, the accomplishment of applicable [related investigative 
action and] corrective actions.

The related investigative action is a detailed inspection of the jack 
anchorage fitting for damage, corrosion, cracks or other defects. 
Corrective actions include replacing the special washer with a new 
special washer and repairing the jack anchorage fitting if there are 
signs of damage, corrosion, or other defects. You may obtain further 
information by examining the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued Airbus Service Bulletin A320-57-1169, Revision 
01, dated September 18, 2012, and the following tasks in Subject 57-26-
13, Attachment--Main Landing Gear, of Chapter 57, Wings, of the Airbus 
A318/A319/A320/A321 Aircraft Maintenance Manual (AMM), Revision 50, 
dated November 1, 2012.
     Task 57-26-13-400-001-A, Installation of the Bearing 
Assembly of the Forward Pintle Pin.
     Task 57-26-13-400-002-A, Installation of the Bearing 
Assembly of the MLG Actuator Attachment.
     Task 57-26-13-400-004-A, Installation of the Bearing Seals 
of the MLG Actuator Bearing Assembly.
    The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

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.

Differences Between This Proposed AD and the MCAI or Service 
Information

    Airbus Service Bulletin A320-57-1169, Revision 01, dated September 
18, 2012, specifies to contact the manufacturer for instructions on how 
to repair certain conditions, but this proposed AD would require 
repairing those conditions using a method approved by either the 
Manager, International Branch, ANM-116, Transport Airplane Directorate, 
FAA; or the EASA (or its delegated agent).

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 851 products of U.S. registry. We also estimate that 
it would take about 3 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 the proposed 
AD on U.S. operators to be

[[Page 39192]]

$217,005, or $255 per product. In addition, we estimate that any 
necessary follow-on actions would take about 15 work-hours, for a cost 
of $1,275 per product. We have received no definitive data that would 
enable us to provide part cost estimates for the on-condition actions 
specified in this proposed AD. We have no way of determining the number 
of products that may 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 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.
