ACTION: Final rule.
AGENCY:
We are superseding an
existing 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 for EMBRAER
Model ERJ 170 airplanes describes the
unsafe condition as:

SUMMARY:
It has been found the occurrence of an
engine in-flight shutdown caused by the
LPCV [low pressure check valves] failing to
close due to excessive wear, which leads to
the concern that such fault may be present
in both engines of a given aircraft.

were no IFSD related to LPCV * * * failure,
some ERJ 190 valves * * * were inspected
and presented cracks due to low cycle

lead to an engine in-flight shutdown and
since both engines of the airplane have the

occurrence of a dual engine IFSD due to
LPCV failure.

*
*
*
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective
August 26, 2010.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in this AD
as of August 26, 2010.

The required actions include repetitive
replacements of the low-stage check
valves and associated seals of the lefthand and right-hand engine bleed
system with new or serviceable valves,
depending on the model. For certain
airplanes, this AD also includes an
optional terminating action for the
repetitive replacements. This AD also
requires, if the terminating action is
done, revising the approved
maintenance plan to include repetitive
functional tests of the low-stage check
valve. For certain other airplanes, this
AD requires replacing a certain lowstage check valve with an improved
low-stage check valve. You may obtain
further information by examining the
MCAI in the AD docket.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the comment received. The
Air Line Pilots Association,
International (ALPA), supports the
NPRM.

The MCAI for EMBRAER Model ERJ 190
airplanes states:
Explanation of Change Made to This
AD
Since we issued the NPRM, we have
received Revision 6, of EMBRAER 170
Maintenance Review Board Report
(MRBR), MRB–1621, dated January 14,
2010. We have updated the final rule to
reference EMBRAER 170 Maintenance
Review Board Report (MRBR), MRB–
1621, Revision 6, dated January 14,
2010. We have added paragraph (j)(14)
to this final rule to give credit for
revising the maintenance program to
include maintenance Task 36–11–02–
002 (Low Stage Bleed Check Valve)
specified in Section 1 of the EMBRAER
170 Maintenance Review Board Report
(MRBR), MRB–1621, Revision 5, dated
November 5, 2008.
We also revised paragraph (j)(13) of
this AD to clarify that doing a
replacement before the effective date of
this AD is acceptable for compliance
with a replacement specified in
paragraph (j)(1) of this AD.
An occurrence of an uncommanded engine
in-flight shutdown (IFSD) was reported on 20
Sep. 2005, which was caused by an ERJ 170
defective LPCV [part number] P/N 1001447–
3 logging 3900 Flight Hours (FH). The valve
failed to close due to excessive wear. Despite
there were no IFSD related to LPCV P/N
Conclusion
We reviewed the available data,
including the comment received, and
determined that air safety and the
public interest require adopting the AD
with the changes described previously.
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 March 4, 2010 (75 FR 9816),
and proposed to supersede AD 2007–
16–09, Amendment 39–15148 (72 FR
44734, August 9, 2007). That NPRM
proposed to correct an unsafe condition
for the specified products. The MCAI for
EMBRAER Model ERJ 170 airplanes
states:
It has been found the occurrence of an
engine in-flight shutdown caused by the
LPCV [low pressure check valves] failing to
close due to excessive wear, which leads to
the concern that such fault may be present
in both engines of a given aircraft.

Federal Register / Vol. 75, No. 140 / Thursday, July 22, 2010 / Rules and Regulations
We have determined that these changes
will not increase the economic burden
on any operator or increase the scope of
the AD.
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.
We might also have required different
actions in this AD from those in the
MCAI in order to follow our FAA
policies. Any such differences are
highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect
about 231 products of U.S. registry.
The actions that are required by AD
2007–16–09 and retained in this AD,
which are provided in the following
table, provide the estimated costs, at an
average labor rate of $85 per work hour,
for U.S. operators to comply with this
AD. The parts manufacturer states that
it will supply required parts to operators
at no cost.
ESTIMATED COSTS
Action
Cost per airplane

$255 per replacement
cycle.
55
$14,025 per replacement
cycle.

$255 per replacement
cycle.
75
$19,125 per replacement

Replacement of right-hand check valves on Model
ERJ 170–100 LR, –100 STD, –100 SE, and –100
SU airplanes.
Replacement of left-hand check valves on Model
ERJ 170–100 LR, –100 STD, –100 SE, –100 SU,
–200 LR, –200 STD, and –200 SU airplanes.
We estimate that it will take about 6
work-hours per product to comply with
the new basic requirements of this AD.
The average labor rate is $85 per workhour. Required parts will cost about
$4,219 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 costs. 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
this AD to the U.S. operators to be
$1,092,399, or $4,729 per product.
emcdonald on DSK2BSOYB1PROD with RULES
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.

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.

Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by
removing Amendment 39–15148 (72 FR
44734, August 9, 2007) and adding the
following new AD:

Effective Date
(a) This airworthiness directive (AD)
becomes effective August 26, 2010.
Affected ADs
(b) This AD supersedes AD 2007–16–09,
Amendment 39–15148.
Applicability
(c) This AD applies to the airplanes
identified in paragraphs (c)(1) and (c)(2) of
this AD, certificated in any category.

Subject
(d) Air Transport Association (ATA) of
America Code 36: Pneumatic.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) for
EMBRAER Model ERJ 170 airplanes states:
It has been found the occurrence of an
engine in-flight shutdown caused by the
LPCV [low pressure check valves] failing to
close due to excessive wear, which leads to
the concern that such fault may be present
in both engines of a given aircraft.
*
*
*
*
*
The MCAI for EMBRAER Model ERJ 190
airplanes states:
An occurrence of an uncommanded engine
in-flight shutdown (IFSD) was reported on 20
Sep. 2005, which was caused by an ERJ 170
defective LPCV P/N 1001447–3 logging 3,900
Flight Hours (FH). The valve failed to close
due to excessive wear. Despite there were no
IFSD related to LPCV P/N 1001447–4 failure,
some ERJ 190 valves P/N 1001447–4 logging
around 2472 FH were inspected and
presented cracks due to low cycle fatigue.
Since this failure mode also might lead to an
engine in-flight shutdown and since both
engines of the airplane have the same valves,
there is a possibility of an occurrence of a
dual engine IFSD due to LPCV failure.

ACTION: Final rule.
AGENCY:
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:
SUMMARY:
Several cases of corrosion and damage on
the Down Drive Shafts (DDS), between the
Down Drive Gear Box (DDGB) and the Input
Gear Box (IPGB), on all 10 Flap Tracks (5 per
wing), have been reported by AIRBUS Long
Range Operators.
Investigations have revealed that corrosion
and wear due to absence of grease in the
spline interfaces could cause [DDS]
disconnection which could result in a free
movable flap surface, potentially leading to
aircraft asymmetry or even flap detachment.
*
*
*
*
*
The unsafe condition could reduce
the ability of the flightcrew to maintain
the safe flight and landing of the
airplane. We are issuing this AD to
require actions to correct the unsafe
condition on these products.

-----------------------------------------------------------------------
SUMMARY: We are superseding an existing 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 for EMBRAER Model ERJ 170
airplanes describes the unsafe condition as:
It has been found the occurrence of an engine in-flight shutdown
caused by the LPCV [low pressure check valves] failing to close due
to excessive wear, which leads to the concern that such fault may be
present in both engines of a given aircraft.
* * * * *
The MCAI for EMBRAER Model ERJ 190 airplanes describes the unsafe
condition as:
An occurrence of an uncommanded engine in-flight shutdown (IFSD) was
reported * * *, which was caused by an ERJ 170 defective LPCV * * *.
The valve failed to close due to excessive wear. Despite there were
no IFSD related to LPCV * * * failure, some ERJ 190 valves * * *
were inspected and presented cracks due to low cycle fatigue. Since
this failure mode also might lead to an engine in-flight shutdown
and since both engines of the airplane have the same valves, there
is a possibility of an occurrence of a dual engine IFSD due to LPCV
failure.
* * * * *
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective August 26, 2010.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of August 26,
2010.
ADDRESSES: You may examine the AD docket on the Internet at https://www.regulations.gov or in person at the U.S. Department of

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 March 4, 2010 (75 FR
9816), and proposed to supersede AD 2007-16-09, Amendment 39-15148 (72
FR 44734, August 9, 2007). That NPRM proposed to correct an unsafe
condition for the specified products. The MCAI for EMBRAER Model ERJ
170 airplanes states:
It has been found the occurrence of an engine in-flight shutdown
caused by the LPCV [low pressure check valves] failing to close due
to excessive wear, which leads to the concern that such fault may be
present in both engines of a given aircraft.
* * * * *
The MCAI for EMBRAER Model ERJ 190 airplanes states:
An occurrence of an uncommanded engine in-flight shutdown (IFSD)
was reported on 20 Sep. 2005, which was caused by an ERJ 170
defective LPCV [part number] P/N 1001447-3 logging 3900 Flight Hours
(FH). The valve failed to close due to excessive wear. Despite there
were no IFSD related to LPCV P/N 1001447-4 failure, some ERJ 190
valves P/N 1001447-4 logging around 2472 FH were inspected and
presented cracks due to low cycle fatigue. Since this failure mode
also might lead to an engine in-flight shutdown and since both
engines of the airplane have the same valves, there is a possibility
of an occurrence of a dual engine IFSD due to LPCV failure.
* * * * *
The required actions include repetitive replacements of the low-stage
check valves and associated seals of the left-hand and right-hand
engine bleed system with new or serviceable valves, depending on the
model. For certain airplanes, this AD also includes an optional
terminating action for the repetitive replacements. This AD also
requires, if the terminating action is done, revising the approved
maintenance plan to include repetitive functional tests of the low-
stage check valve. For certain other airplanes, this AD requires
replacing a certain low-stage check valve with an improved low-stage
check valve. You may obtain further information by examining the MCAI
in the AD docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comment received. The Air Line Pilots
Association, International (ALPA), supports the NPRM.
Explanation of Change Made to This AD
Since we issued the NPRM, we have received Revision 6, of EMBRAER
170 Maintenance Review Board Report (MRBR), MRB-1621, dated January 14,
2010. We have updated the final rule to reference EMBRAER 170
Maintenance Review Board Report (MRBR), MRB-1621, Revision 6, dated
January 14, 2010. We have added paragraph (j)(14) to this final rule to
give credit for revising the maintenance program to include maintenance
Task 36-11-02-002 (Low Stage Bleed Check Valve) specified in Section 1
of the EMBRAER 170 Maintenance Review Board Report (MRBR), MRB-1621,
Revision 5, dated November 5, 2008.
We also revised paragraph (j)(13) of this AD to clarify that doing
a replacement before the effective date of this AD is acceptable for
compliance with a replacement specified in paragraph (j)(1) of this AD.
Conclusion
We reviewed the available data, including the comment received, and
determined that air safety and the public interest require adopting the
AD with the changes described previously.
[[Page 42586]]
We have determined that these changes will not increase the economic
burden on any operator or increase the scope of the AD.
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.
We might also have required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect about 231 products of U.S.
registry.
The actions that are required by AD 2007-16-09 and retained in this
AD, which are provided in the following table, provide the estimated
costs, at an average labor rate of $85 per work hour, for U.S.
operators to comply with this AD. The parts manufacturer states that it
will supply required parts to operators at no cost.
Estimated Costs

100 STD, -100 SE, -100 SU, -200
LR, -200 STD, and -200 SU
airplanes.
----------------------------------------------------------------------------------------------------------------
We estimate that it will take about 6 work-hours per product to
comply with the new basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts will cost about $4,219 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 costs. 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 this AD to the
U.S. operators to be $1,092,399, or $4,729 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 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.
Examining the AD Docket
You may examine the AD docket on the Internet at https://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone (800) 647-5527) is in the
ADDRESSES section. Comments will be available in the AD docket shortly
after receipt.

An occurrence of an uncommanded engine in-flight shutdown (IFSD)
was reported on 20 Sep. 2005, which was caused by an ERJ 170
defective LPCV P/N 1001447-3 logging 3,900 Flight Hours (FH). The
valve failed to close due to excessive wear. Despite there were no
IFSD related to LPCV P/N 1001447-4 failure, some ERJ 190 valves P/N
1001447-4 logging around 2472 FH were inspected and presented cracks
due to low cycle fatigue. Since this failure mode also might lead to
an engine in-flight shutdown and since both engines of the airplane
have the same valves, there is a possibility of an occurrence of a
dual engine IFSD due to LPCV failure.
* * * * *
The required actions include repetitive replacements of the low-
stage check valves and associated seals of the left-hand and right-
hand engine bleed system with new or serviceable valves, depending
on the model. For certain airplanes, this AD also includes an
optional terminating action for the repetitive replacements. This AD
also requires, if the terminating action is done, revising the
approved maintenance plan to include repetitive functional tests of
the low-stage check valve. For certain other airplanes, this AD
requires replacing a certain low-stage check valve with an improved
low-stage check valve.
