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).

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.

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

Federal Register / Vol. 75, No. 92 / Thursday, May 13, 2010 / Rules and Regulations
under the criteria of the Regulatory
Flexibility Act.
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.
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.
cprice-sewell on DSKHWCL6B1PROD with RULES
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.
§ 39.13
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.
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:

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

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:

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.

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.
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 under the criteria
of the Regulatory Flexibility Act.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
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.
