ACTION: Final rule; request for comments. Examining the AD Docket SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above that supersedes an existing AD. This 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: * * * * * Engineering analysis using the new calculated loads has shown that the structural integrity of the forward engine mount cannot be guaranteed after either thrust link has accumulated 15500 Flight Cycles (FC). cprice-sewell on DSKHWCL6B1PROD with RULES * * * * * A loss of structural integrity of the forward engine mounts could lead to the loss of the load path for the forward engine mount and damage to other engine mount structures, which could result in failure of the forward engine mount, possible separation of the engine from the airplane, damage to the wing, or loss of control of the airplane. This AD requires actions that are intended to address the unsafe condition described in the MCAI. VerDate Mar<15>2010 11:30 May 12, 2010 Jkt 220001 DATES: This AD becomes effective May 28, 2010.

SUPPLEMENTARY INFORMATION: Discussion On December 30, 2009, we issued AD 2010–02–03, Amendment 39–16174 (75 FR 2057, January 14, 2010). That AD required actions intended to address an unsafe condition on the products listed above.

Airbus notes that Airbus Mandatory Service Bulletin A340–71–4006, Revision 01, dated May 14, 2009, calculates the limits using flight cycles. We have revised paragraph (g)(1)(ii) of this AD to refer to a compliance time specified in flight cycles accordingly. 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 the same type design. There are no products of this type currently registered in the United States. However, this rule is necessary to ensure that the described unsafe condition is addressed if any of these products are placed on the U.S. Register in the future. Differences Between the 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. We might also have required 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 AD.

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

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 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); and 3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities Reason (e) The mandatory continued airworthiness information (MCAI) states: ‘‘A recent review of the A340–200/300 fleet has shown that the current utilization rate of the aeroplanes is different from the assumptions used at the time of A340 initial certification. New calculations have been performed taking into account an updated mission profile to determine the impact to the loads on the forward engine mount. Engineering analysis using the new calculated loads has shown that the structural integrity of the forward engine mount cannot be guaranteed after either thrust link has accumulated 15500 Flight Cycles (FC). Consequently, this AD introduces a Limit Of Validity (LOV) of 15 500 FC for CFM 56– 5C forward engine mount thrust links Part Number (P/N) 340–7005–3 and P/N 340– 7005–4.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on July 22, 2009 (74 FR 36129). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: It has been found the occurrence of outboard slat skew sensor failure in open or closed position. The combination of an outboard slat skew sensor failed closed, an outboard slat actuator structural failure (rupture) and its adjacent actuator torque limiter failing high (allows higher loads to the panel structure) occurring in the same slat surface, under normal flight loads, may lead [the] slat surface to detach from the wing with the possibility of hitting and damaging the horizontal stabilizer and elevator, which may affect the airplane controllability. SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This 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: * It has been found the occurrence of outboard slat skew sensor failure in open or closed position. The combination of an outboard slat skew sensor failed closed, an outboard slat actuator structural failure (rupture) and its adjacent actuator torque limiter failing high (allows higher loads to the panel structure) occurring in the same slat surface, under normal flight loads, may lead [the] slat surface to detach from the wing with the possibility of hitting and damaging the horizontal stabilizer and elevator, which may affect the airplane controllability.

You may obtain further information by examining the MCAI in the AD docket. Comments Request To Remove Reference to the Revision Level of the Airplane Maintenance Manual (AMM) Task Embraer requests that we remove reference to the specific revision of the AMM task specified in Note 1 of the NPRM. Embraer explains that since AMMs are often revised to improve task procedures, changes to other tasks might force the subsequent tasks to be ‘‘repaged and re-dated.’’ Embraer points out that changes made to improve task procedures do not change the intent of the tasks and that the specific task number will always refer to the specific task, regardless of revision level. Embraer notes that referring to a specific revision will cause operators to request alternative methods of compliance (AMOCs) for updated AMM tasks that might be identical. Embraer suggests that if it is necessary to refer to a specific revision of the AMM, we should not refer to the AMM task, but instead include the text of the E:\FR\FM\13MYR1.SGM 13MYR1

Series Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above that supersedes an existing AD. This 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:
* * * * *
    Engineering analysis using the new calculated loads has shown 
that the structural integrity of the forward engine mount cannot be 
guaranteed after either thrust link has accumulated 15500 Flight 
Cycles (FC).
* * * * *
    A loss of structural integrity of the forward engine mounts could 
lead to the loss of the load path for the forward engine mount and 
damage to other engine mount structures, which could result in failure 
of the forward engine mount, possible separation of the engine from the 
airplane, damage to the wing, or loss of control of the airplane. This 
AD requires actions that are intended to address the unsafe condition 
described in the MCAI.

DATES: This AD becomes effective May 28, 2010.
    On January 29, 2010 (75 FR 2057, January 14, 2010), the Director of 
the Federal Register approved the incorporation by reference of a 
certain publication listed in this AD.
    We must receive comments on this AD by June 28, 2010.

SUPPLEMENTARY INFORMATION:

Discussion

    On December 30, 2009, we issued AD 2010-02-03, Amendment 39-16174 
(75 FR 2057, January 14, 2010). That AD required actions intended to 
address an unsafe condition on the products listed above.
    Since we issued AD 2010-02-03, Airbus requested that we clarify the 
compliance time for airplanes with thrust links for which the part 
history is partial or unknown as specified in paragraph (g)(1)(ii) of 
the original AD. Airbus notes that Airbus Mandatory Service Bulletin 
A340-71-4006, Revision 01, dated May 14, 2009, calculates the limits 
using flight cycles. We have revised paragraph (g)(1)(ii) of this AD to 
refer to a compliance time specified in flight cycles accordingly.

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 the same 
type design.
    There are no products of this type currently registered in the 
United States. However, this rule is necessary to ensure that the 
described unsafe condition is addressed if any of these products are 
placed on the U.S. Register in the future.

Differences Between the 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.
    We might also have required 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 AD.

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this product, 
notice and opportunity for public comment before issuing this AD are 
unnecessary.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and

[[Page 26882]]

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-2010-0476; Directorate Identifier 
2010-NM-036-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 https://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.

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.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The FAA amends Sec.  39.13 by removing Amendment 39-16174 (75 FR 
2057, January 14, 2010) and adding the following new AD:

2010-10-19 Airbus: Amendment 39-16298. Docket No. FAA-2010-0476, 
Directorate Identifier 2010-NM-036-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective May 28, 
2010.

Affected ADs

    (b) This AD supersedes AD 2010-02-03, Amendment 39-16174.

Applicability

    (c) This AD applies to Airbus Model A340-211, -212, -213, -311, 
-312, and -313 airplanes, all manufacturer serial numbers; 
certificated in any category.

Subject

    (d) Air Transport Association (ATA) of America Code 71: 
Powerplant.

Reason

    (e) The mandatory continued airworthiness information (MCAI) 
states:

    ``A recent review of the A340-200/300 fleet has shown that the 
current utilization rate of the aeroplanes is different from the 
assumptions used at the time of A340 initial certification. New 
calculations have been performed taking into account an updated 
mission profile to determine the impact to the loads on the forward 
engine mount.
    Engineering analysis using the new calculated loads has shown 
that the structural integrity of the forward engine mount cannot be 
guaranteed after either thrust link has accumulated 15500 Flight 
Cycles (FC).
    Consequently, this AD introduces a Limit Of Validity (LOV) of 15 
500 FC for CFM 56-5C forward engine mount thrust links Part Number 
(P/N) 340-7005-3 and P/N 340-7005-4.
    In addition, this AD requires establishing the deadline for 
replacement of forward engine mount thrust link assemblies, to trace 
the life of these assemblies and to replace them no later than the 
calculated deadline.''

    A loss of structural integrity of the forward engine mounts 
could lead to the loss of the load path for the forward engine mount 
and damage to other engine mount structures, which could result in 
failure of the forward engine mount, possible separation of the 
engine from the airplane, damage to the wing, or loss of control of 
the airplane.

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) Do the following actions.
    (1) At the applicable time specified in paragraph (g)(1)(i) or 
(g)(1)(ii) of this AD: Calculate the flight cycles, as applicable, 
and replace all CFM 56-5C forward engine mount thrust links P/N 340-
7005-3 or P/N 340-7005-4, in accordance with the Accomplishment 
Instructions of Airbus Mandatory Service Bulletin A340-71-4006, 
Revision 01, dated May 14, 2009.

    Note 1: P/N 340-7005-3 and P/N 340-7005-4 are the part numbers 
for only the link. P/N 340-7005-503 and P/N 340-7005-504 are the 
part numbers for the assembly (comprising the bearing and the link).

    (i) For airplanes with thrust links for which the history of the 
part is available: Replace in accordance with Airbus Mandatory 
Service Bulletin A340-71-4006, Revision 01, dated May 14, 2009, 
prior to the accumulation of 15,500 total flight cycles on the part, 
or within 90 days from the effective date of the AD, whichever 
occurs later.
    (ii) For airplanes with thrust links for which the part history 
is partial or unknown: Within 30 days after the effective date of 
this AD, calculate the limit for replacement in accordance with the 
calculation method provided in Airbus Mandatory Service Bulletin 
A340-71-4006, Revision 01, dated May 14, 2009, and replace the part 
no later than the calculated limit for replacement.
    (2) Repeat the replacement required by paragraph (g)(1) of this 
AD at intervals not to exceed 15,500 flight cycles on the part in 
accordance with the Accomplishment Instructions of Airbus Mandatory 
Service Bulletin A340-71-4006, Revision 01, dated May 14, 2009.
