PO 00000 Frm 00024 Fmt 4702 Sfmt 4702 61645 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 2010–0205, dated October 8, 2010 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: During fatigue testing of the MLG [main landing gear], three failures of the retraction bracket occurred before the calculated life limitation. Further analysis has confirmed that those failures were due to fatigue initiated by fretting between the bush and lug bore. The failure of the retraction bracket, if not detected, could lead to a MLG extension with no damping resulting in MLG structural damage. Airbus carried out an investigation, demonstrating that the life limit of retraction brackets must be reduced to 19,800 Landings (LDG), which is below the life limit stated in the following A330 and A340 Airbus ALS Part 4 revisions: —Airbus A330 ALS Part 4 revision 02 approved by EASA on 16 December 2009. —Airbus A340 ALS Part 4 revision 01 approved by EASA on 15 December 2009. In order to maintain the structural integrity of the aeroplane, this [EASA] AD requires the replacement of these MLG retraction brackets before the accumulation of 19,800 total LDG. You may obtain further information by examining the MCAI in the AD docket. 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 AD and the MCAI or Service Information We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. E:\FR\FM\05OCP1.SGM 05OCP1 61646 Federal Register / Vol. 76, No. 193 / Wednesday, October 5, 2011 / Proposed Rules We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the proposed AD. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 29 products of U.S. registry. We also estimate that it would take about 25 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 about $200,000 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 $5,861,625, or $202,125 per product. jlentini on DSK4TPTVN1PROD with PROPOSALS 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; VerDate Mar<15>2010 16:06 Oct 04, 2011 Jkt 226001 2. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and 3. 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. The failure of the retraction bracket, if not detected, could lead to a MLG extension with no damping resulting in MLG structural damage. List of Subjects in 14 CFR Part 39 (g) Before the accumulation of 19,800 total landings on the retraction brackets of the main landing gear or within 900 flight hours after the effective date of this AD, whichever occurs later: Replace the affected retraction bracket of the MLG specified in table 1 of this AD with a serviceable part, in accordance with a method approved by the Manager, International Branch, ANM–116, FAA, or European Aviation Safety Agency (EASA) (or its delegated agent). Thereafter, before the accumulation of 19,800 total landings on any retraction bracket of the MLG identified in table 1 of this AD, replace the retraction bracket with a serviceable part, in accordance with a method approved by the Manager, International Branch, ANM–116, FAA, or EASA (or its delegated agent).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed AD results from mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as:

    During fatigue testing of the MLG [main landing gear], three 
failures of the retraction bracket occurred before the calculated 
life limitation. Further analysis has confirmed that those failures 
were due to fatigue initiated by fretting between the bush and lug 
bore.
    The failure of the retraction bracket, if not detected, could 
lead to a MLG extension with no damping resulting in MLG structural 
damage.
* * * * *
    The proposed AD would require actions that are intended to address 
the unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by November 21, 
2011.

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 2010-0205, dated October 8, 2010 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    During fatigue testing of the MLG [main landing gear], three 
failures of the retraction bracket occurred before the calculated 
life limitation. Further analysis has confirmed that those failures 
were due to fatigue initiated by fretting between the bush and lug 
bore.
    The failure of the retraction bracket, if not detected, could 
lead to a MLG extension with no damping resulting in MLG structural 
damage.
    Airbus carried out an investigation, demonstrating that the life 
limit of retraction brackets must be reduced to 19,800 Landings 
(LDG), which is below the life limit stated in the following A330 
and A340 Airbus ALS Part 4 revisions:

--Airbus A330 ALS Part 4 revision 02 approved by EASA on 16 December 
2009.
--Airbus A340 ALS Part 4 revision 01 approved by EASA on 15 December 
2009.

    In order to maintain the structural integrity of the aeroplane, 
this [EASA] AD requires the replacement of these MLG retraction 
brackets before the accumulation of 19,800 total LDG.

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

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 AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.

[[Page 61646]]

    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 29 products of U.S. registry. We also estimate that 
it would take about 25 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 about $200,000 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 $5,861,625, or $202,125 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 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); and
    3. 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.

List of Subjects in 14 CFR Part 39

reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Airbus: Docket No. FAA-2011-0997; Directorate Identifier 2011-NM-
043-AD.

Comments Due Date

    (a) We must receive comments by November 21, 2011.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Airbus Model A330-201, -202, -203, -223, 
-243, -301, -302, -303, -321, -322, -323, -341, -342, and -343 
airplanes; and Model A340-211, -212, -213, -311, -312, and -313 
airplanes; certificated in any category, all manufacturer serial 
numbers; except airplanes on which Airbus modification 54500 has 
been embodied in production; and except airplanes on which Airbus 
Service Bulletin A330-32-3212 or Airbus Service Bulletin A340-32-
4256 has been embodied in service; as applicable to airplane model.

Subject

    (d) Air Transport Association (ATA) of America Code 32: Landing 
Gear.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    During fatigue testing of the MLG [main landing gear], three 
failures of the retraction bracket occurred before the calculated 
life limitation. Further analysis has confirmed that those failures 
were due to fatigue initiated by fretting between the bush and lug 
bore.
    The failure of the retraction bracket, if not detected, could 
lead to a MLG extension with no damping resulting in MLG structural 
damage.
* * * * *

Compliance

    (f) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Actions

    (g) Before the accumulation of 19,800 total landings on the 
retraction brackets of the main landing gear or within 900 flight 
hours after the effective date of this AD, whichever occurs later: 
Replace the affected retraction bracket of the MLG specified in 
table 1 of this AD with a serviceable part, in accordance with a 
method approved by the Manager, International Branch, ANM-116, FAA, 
or European Aviation Safety Agency (EASA) (or its delegated agent). 
Thereafter, before the accumulation of 19,800 total landings on any 
retraction bracket of the MLG identified in table 1 of this AD, 
replace the retraction bracket with a serviceable part, in 
accordance with a method approved by the Manager, International 
Branch, ANM-116, FAA, or EASA (or its delegated agent).
