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 2011–0202, dated October 13, 2011 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: After a push back from the gate, an A320 aeroplane was preparing to initiate taxi, PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 60331 when an uncommanded nose landing gear (NLG) retraction occurred, causing the nose of the aeroplane to hit the ground. Investigations revealed that the retraction was caused by a combination of a power interruption to LGCIUs [landing gear control interface unit] and an internal hydraulic leak through the landing gear (LG) selector valve 40GA. Deeper investigations have revealed that LGCIU power interruption appears during engine start at each flight. Even though no incident has been reported in service, it has been determined that a non compliance to the safety objective exists when combined with a dormant single failure of the selector valve seal leaking. This condition, if not corrected, could lead to further incidents of untimely unlocking and/or retraction of the NLG which, while on the ground, could result in injury to ground personnel and damage to the aeroplane. To address the possible hydraulic leak of the LG selector valve, EASA issued AD 2007– 0065, currently at Revision 2. For the reasons described above, this [EASA] AD requires installation of a power interruption protection circuit to the LGCIU and the accomplishment of associated modifications [install new seals on nose landing gear (NLG)/main landing gear (MLG) door valve selector and gear valve-selector and for certain airplanes, re-identification of identification plates]. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued the following service bulletins: • Airbus Service Bulletin A320–32– 1346, Revision 04, including Appendices 1 and 2, dated April 22, 2011 (for Model A318, A319, A320, and A321 series airplanes). • Airbus Service Bulletin A320–32– 1349, Revision 03, including Appendix 1, dated October 5, 2011 (for Model A319CJ (corporate jet) airplanes). 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. E:\FR\FM\03OCP1.SGM 03OCP1 60332 Federal Register / Vol. 77, No. 192 / Wednesday, October 3, 2012 / Proposed Rules Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 755 products of U.S. registry. We also estimate that it would take about 48 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 up to $8,220 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be up to $9,286,500, or up to $12,300 per product. 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. erowe on DSK2VPTVN1PROD with 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 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 VerDate Mar<15>2010 14:54 Oct 02, 2012 Jkt 229001 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.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Airbus Model A318, A319, A320, and A321 series airplanes. This 
proposed AD was prompted by a report of an uncommanded nose landing 
gear (NLG) retraction. This proposed AD would require installing a 
power interruption protection circuit for the landing gear control 
interface unit (LGCIU). We are proposing this AD to prevent untimely 
unlocking and/or retraction of the NLG, which, while on the ground, 
could result in injury to ground personnel and damage to the airplane.

DATES: We must receive comments on this proposed AD by November 19, 
2012.

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 2011-0202, dated October 13, 2011 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    After a push back from the gate, an A320 aeroplane was preparing 
to initiate taxi, when an uncommanded nose landing gear (NLG) 
retraction occurred, causing the nose of the aeroplane to hit the 
ground. Investigations revealed that the retraction was caused by a 
combination of a power interruption to LGCIUs [landing gear control 
interface unit] and an internal hydraulic leak through the landing 
gear (LG) selector valve 40GA.
    Deeper investigations have revealed that LGCIU power 
interruption appears during engine start at each flight. Even though 
no incident has been reported in service, it has been determined 
that a non compliance to the safety objective exists when combined 
with a dormant single failure of the selector valve seal leaking.
    This condition, if not corrected, could lead to further 
incidents of untimely unlocking and/or retraction of the NLG which, 
while on the ground, could result in injury to ground personnel and 
damage to the aeroplane.
    To address the possible hydraulic leak of the LG selector valve, 
EASA issued AD 2007-0065, currently at Revision 2.
    For the reasons described above, this [EASA] AD requires 
installation of a power interruption protection circuit to the LGCIU 
and the accomplishment of associated modifications [install new 
seals on nose landing gear (NLG)/main landing gear (MLG) door valve 
selector and gear valve-selector and for certain airplanes, re-
identification of identification plates].

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Airbus has issued the following service bulletins:
     Airbus Service Bulletin A320-32-1346, Revision 04, 
including Appendices 1 and 2, dated April 22, 2011 (for Model A318, 
A319, A320, and A321 series airplanes).
     Airbus Service Bulletin A320-32-1349, Revision 03, 
including Appendix 1, dated October 5, 2011 (for Model A319CJ 
(corporate jet) airplanes).
    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.

    Based on the service information, we estimate that this proposed AD 
would affect about 755 products of U.S. registry. We also estimate that 
it would take about 48 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 up to $8,220 per product. Where 
the service information lists required parts costs that are covered 
under warranty, we have assumed that there will be no charge for these 
parts. As we do not control warranty coverage for affected parties, 
some parties may incur costs higher than estimated here. Based on these 
figures, we estimate the cost of the proposed AD on U.S. operators to 
be up to $9,286,500, or up to $12,300 per product.

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 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.
