Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. 
(EMBRAER) Model ERJ 170 and ERJ 190 Airplanes

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

ACTION: Final rule.

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

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.

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

 airplanes.
Replacement of left-hand check                 3  $255 per replacement                 75  $19,125 per
 valves on Model ERJ 170-100 LR, -                 cycle.                                   replacement cycle.
 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 http://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.

[[Page 42587]]

Model ERJ 170-200 LR, -200 STD, and -200 SU airplanes; equipped with 
Hamilton Sundstrand low pressure check valve (LPCV) having part 
number (P/N) 1001447-3.
    (2) Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 
190-100 ECJ, -100 LR, -100 IGW, -100 STD airplanes; and Model ERJ 
190-200 STD, -200 LR, and -200 IGW airplanes; equipped with Hamilton 
Sundstrand LPCV having P/N 1001447-3 or 1001447-4.

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.
* * * * *
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.
    Restatement of Requirements of AD 2005-23-14, With Revised 
Service Information:

Replacement for Right-Hand (RH) Engine on Model ERJ 170-100 LR, -100 
STD, -100 SE, and -100 SU Airplanes

    (f) For Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU 
airplanes: Within 100 flight hours after November 29, 2005 (the 
effective date of AD 2005-23-14, which was superseded by AD 2007-16-
09), or prior to the accumulation of 3,000 total flight hours, 
whichever occurs later, replace the low-stage check valve and 
associated seals of the RH engine's engine bleed system with a new 
check valve and new seals, in accordance with the Accomplishment 
Instructions of EMBRAER Alert Service Bulletin 170-36-A004, dated 
September 28, 2005; or paragraph 3.C. of the Accomplishment 
Instructions of EMBRAER Service Bulletin 170-36-0004, dated November 
18, 2005, or Revision 01, dated March 10, 2008. As of the effective

Revision 01, dated March 10, 2008. Repeat the replacement thereafter 
at intervals not to exceed 3,000 flight hours.

Removed Check Valves

    (g) Although EMBRAER Alert Service Bulletin 170-36-A004, dated 
September 28, 2005, specifies to send removed check valves to the 
manufacturer, this AD does not include that requirement.
    Restatement of Certain Requirements of AD 2007-16-09, With 
Revised Service Information:

Replacement for Left-Hand (LH) Engine on All Model ERJ 170 Airplanes

    (h) For Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 
LR, -200 STD, and -200 SU airplanes: Within 300 flight hours after 
September 13, 2007 (the effective date of AD 2007-16-09) or prior to 
the accumulation of 3,000 total flight hours, whichever occurs 
later, replace the low-stage check valve and associated seals of the 
LH engine's engine bleed system with a new check valve and new 
seals, in accordance with paragraph 3.B. of the Accomplishment 
Instructions of EMBRAER Service Bulletin 170-36-0004, dated November 
18, 2005; or Revision 01, dated March 10, 2008. As of the effective 
date of this AD, only use EMBRAER Service Bulletin 170-36-0004, 
Revision 01, dated March 10, 2008. Repeat the replacement thereafter 
at intervals not to exceed 3,000 flight hours.

Removed Check Valves in Accordance With New Service Bulletin

    (i) Although EMBRAER Service Bulletin 170-36-0004, dated 
November 18, 2005, specifies to send removed check valves to the 
manufacturer, this AD does not include that requirement.
    New Requirements of This AD:

Actions and Compliance

    (j) Unless already done, do the following actions.
    (1) For Model ERJ 170-200 LR, -200 STD, and -200 SU airplanes: 
Within 100 flight hours after the effective date of this AD, or 
prior to the accumulation of 3,000 total flight hours, whichever 
occurs later, replace the low-stage check valve and associated seals 
of the RH engine's engine bleed system with a new check valve and 
new seals, in accordance with the Accomplishment Instructions of 
EMBRAER Service Bulletin 170-36-0004, Revision 01, dated March 10, 
2008. Repeat the replacement thereafter at intervals not to exceed 
3,000 flight hours.
    (2) For Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 
LR, -200 STD, and -200 SU airplanes: Replacing the LPCV having P/N 
1001447-3 with a new one having P/N 1001447-4 in accordance with the 
Accomplishment Instructions of EMBRAER Service Bulletin 170-36-0011, 
Revision 02, dated July 19, 2007, terminates the repetitive 
replacements required by paragraphs (f), (h), and (j)(1) of this AD.
    (3) For Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 
LR, -200 STD, and -200 SU airplanes, at the earlier of the times 
specified in paragraphs (j)(3)(i) and (j)(3)(ii) of this AD, revise 
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 6, 
dated January 14, 2010. Thereafter, except as provided by paragraph 
(k) of this AD, no alternative inspection intervals may be approved 
for the task.
    (i) Within 180 days after accomplishing paragraph (j)(2) of this 
AD.
    (ii) Before any LPCV having P/N 1001447-4 accumulates 3,000 
total flight hours, or within 300 flight hours after the effective 
date of this AD, whichever occurs later.
    (4) For Model ERJ 170-100 LR, -100 STD, -100 SE, -100 SU, -200 
LR, -200 STD, and -200 SU airplanes: As of the effective date of 
this AD, no person may install any LPCV identified in paragraph 
(j)(4)(i) or (j)(4)(ii) of this AD on any airplane.
    (i) Any LPCV having P/N 1001447-3, installed on Model ERJ-170

    (ii) Any LPCV having P/N 1001447-3, installed on Model ERJ-170 
and ERJ-190 airplanes, that has accumulated 3,000 or more total 
flight hours. To calculate the equivalent number of flight hours for 
a LPCV having P/N 1001447-3 that was installed on Model ERJ-190 
airplane to be installed on a Model ERJ-170 airplane, the flight 
hours accumulated in operation on ERJ-190 models must be multiplied 
by a factor of 2 (100 percent).
    (5) For Model ERJ 190-100 ECJ, -100 LR, -100 IGW, -100 STD, -200 
STD, -200 LR, and -200 IGW airplanes: Within 100 flight hours after

    (6) For Model ERJ 190-100 ECJ, -100 LR, -100 IGW, -100 STD, -200 
STD, -200 LR, and -200 IGW airplanes: Replace all LPCVs having P/N 
1001447-3 that have accumulated less than 1,500 total flight hours 
as of the effective date of this AD, before the LPCV accumulates 
1,500 total flight hours or within 100 flight hours after the 
effective date of this AD, whichever occurs later. Replace that LPCV 
with a new or serviceable LPCV having P/N 1001447-4 that has 
accumulated less than 2,000 total flight hours since new or since 
overhaul, in accordance with the Accomplishment Instructions of 
EMBRAER Service Bulletin 190-36-0006, Revision 01, dated July 19, 
2007.
    (7) For Model ERJ 190-100 ECJ, -100 LR, -100 IGW, -100 STD, -200 
STD, -200 LR, and -200 IGW airplanes: Within 200 flight

at intervals not to exceed 2,000 total flight hours on the LPCV 
since new or last overhaul.
    (8) For Model ERJ 190-100 ECJ, -100 LR, -100 IGW, -100 STD, -200 
STD, -200 LR, and -200 IGW airplanes: Within 200 flight hours after 
the effective date of this AD, or before any LPCV having P/N 
1001447-4 installed on the left engine accumulates 2,000 total 
flight hours since new or last overhaul, whichever occurs later, 
replace the valve with a new or serviceable LPCV having P/N 1001447-
4 that has accumulated less than 2,000 total flight hours since new 
or since overhaul, in accordance with the Accomplishment 
Instructions of EMBRAER Service Bulletin 190-36-0014, Revision 01, 
dated January 14, 2009. Repeat the replacement on the left engine at 
intervals not to exceed 2,000 total flight hours on the LPCV since 
new or last overhaul.
    (9) For Model ERJ 190-100 ECJ, -100 LR, -100 IGW, -100 STD, -200
