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

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above that would supersede an existing AD. 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 for EMBRAER Model ERJ 170 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 
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

[[Page 9817]]

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. 
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 April 19, 2010.

Discussion

    On July 30, 2007, we issued AD 2007-16-09, Amendment 39-15148 (72 
FR 44734, August 9, 2007). That AD required actions intended to address 
an unsafe condition on the products listed above.
    Since we issued AD 2007-16-09, we have received reports of cracking 
in low-stage check valves having part number (P/N) 1001447-4. The 
Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), which is 
the aviation authority for Brazil, has issued Brazilian Airworthiness 
Directive 2005-09-03R2, effective February 25, 2008 and 2006-11-01R4, 
effective April 9, 2009 (referred to after this as ``the MCAI''), to 
correct an unsafe condition for the specified products. The MCAI for 
EMBRAER Model ERJ 170 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 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 proposed AD also includes an 
optional terminating action for the repetitive replacements. This 
proposed AD would also require, 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 
proposed AD would require 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.

 1 of the EMBRAER 170
 Maintenance Review Board
 Report MRB-1621.
------------------------------------------------------------------------

    The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

Adding New Airplanes

    Since AD 2007-16-09, new models that are affected by the identified 
unsafe condition have been added to the U.S. type certificate data 
sheet and are included in this AD. We have added Models ERJ-190-200 
STD, -200 LR, and -200 IGW to paragraph (c) of this proposed AD.

Clarification of Applicability

    To clarify the affected airplanes, we have reviseds the 
applicability of this proposed AD. AD 2007-16-09 applied to ``all'' of 
the affected models. However, only airplanes equipped with certain 
LPCVs are affected by the identified unsafe condition. We have revised 
paragraph (c) of this AD accordingly.

Change to Existing AD

    This proposed AD would retain certain requirements of AD 2007-16-
09. Since AD 2007-16-09 was issued, the AD format has been revised, and 
certain paragraphs have been rearranged. As a result, the corresponding 
paragraph identifiers have changed in this proposed AD, as listed in 
the following table:

                      Revised Paragraph Identifiers

             paragraph (n)                       paragraph (i).
------------------------------------------------------------------------

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.
    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 231 products of U.S. registry.
    The actions that are required by AD 2007-16-09 and retained in this 
proposed 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
----------------------------------------------------------------------------------------------------------------

Replacement of RH check              3  $255, per                  55  $14,025, per replacement cycle.

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

    We estimate that it would take about 6 work-hours per product to 
comply with the new basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would 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 the proposed AD 
on 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

[[Page 9819]]

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

    Air transportation, Aircraft, Aviation safety, Incorporation by 
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 removing Amendment 39-15148 (72 FR 
44734, August 9, 2007) and adding the following new AD:

Empresa Brasileira de Aeronautica S.A. (EMBRAER): Docket No. FAA-
2010-0174; Directorate Identifier 2009-NM-186-AD.

Comments Due Date

    (a) We must receive comments by April 19, 2010.

Affected ADs

    (b) The 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.
    (1) Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 
170-100 LR, -100 STD, -100 SE, and -100 SU airplanes; and 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 states:
    It has been found the occurrence of an engine in-flight shutdown 
caused by the LPCV 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 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 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.
