RIN 2120-AA64
Airworthiness Directives; Embraer S.A. Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to supersede an existing airworthiness directive
(AD) that applies to certain Embraer S.A. Model ERJ 170 and ERJ 190
airplanes. The existing AD currently requires, for certain airplanes,
repetitively replacing the low-stage check valve and associated seals
of the right hand (RH) engine's engine bleed system with a new check
valve and new seals, replacing the low pressure check valves (LPCV),
and revising the maintenance program. For certain other airplanes, the
existing AD requires replacing a certain low-stage check valve with an
improved low-stage check valve. Since we issued that AD, we have
received reports of uncommanded engine shutdowns on both Model ERJ 170
and ERJ 190 airplanes due to excessive wear and failure of LPCVs having
certain part numbers. This proposed AD would also, for certain
airplanes, require replacing certain LPCVs of the left-hand (LH) and RH
engines, which would be an option for other airplanes. We are proposing
this AD to prevent the possibility of a dual engine in-flight shutdown
due to LPCV failure.
DATES: We must receive comments on this proposed AD by February 11,
2013.

Discussion
On June 23, 2010, we issued AD 2010-14-14, Amendment 39-16359 (75
FR 42585, July 22, 2010). That AD required actions intended to address
an unsafe condition on Embraer S.A. Model ERJ 170 and ERJ 190
airplanes.
Since we issued AD 2010-14-14, Amendment 39-16359 (75 FR 42585,
July 22, 2010), there have been occurrences of uncommanded engine
shutdowns on both Model ERJ 170 and Model ERJ 190 airplanes due to
excessive wear and failure of LPCVs having part number 1001447-3 and
1001447-4. Both engines of the airplanes have the same valves, which
leads to the possibility of a dual engine in-flight shutdown due to
LPCV failure. The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil
(ANAC), which is the aviation authority for Brazil, has issued
Brazilian Airworthiness Directives 2005-09-03R3 and 2006-11-01R6, both
effective May 30, 2011 (referred to after this as ``the MCAI''), to
correct an unsafe condition for the specified products. The MCAI for
Embraer S.A. 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] failure P/N
[part number] 1001447-3 with 3,900 Flight Hours (FH) installed on
ERJ-170. This valve failed [to] open due [to] excessive wear. [I]t
was found the occurrence of an engine shutdown on-ground, caused by
the LPCV failure P/N 1001447-4 with 1,802 FH installed on ERJ-190
failed due [to] low cycle fatigue. Since the behavior of a valve P/N
1001447-4 removed from ERJ-190 is unknown on ERJ-170 and the P/N
1001447-4 is common between ERJ-170 and ERJ-190 airplane fleet, an
action is necessary to prevent the installation, in ERJ-170
airplanes, of LPCVs P/N 1001447-4 previously installed in ERJ-190
airplanes.
* * * * *
The MCAI for Embraer S.A. Model ERJ 190 airplanes states:
It has been found the occurrence of an engine in-flight shutdown
* * * caused by the LPCV failure P/N [part number] 1001447-3 with
3,900 Flight Hours (FH) installed on ERJ-170. This valve failed [to]
open due [to] excessive wear. [I]t was found the occurrence of an
engine shutdown on-ground, caused by
[[Page 75912]]
the LPCV failure P/N 1001447-4 with 1,802 FH installed on ERJ-190
failed due [to] low cycle fatigue. Since the behavior of a valve P/N
1001447-4 removed from ERJ-170 is unknown on ERJ-190 and the P/N
1001447-4 is common between ERJ-170 and ERJ-190 airplane fleet, an
action is necessary to prevent the installation, in ERJ-190
airplanes, of LPCVs P/N 1001447-4 previously installed in ERJ-170
airplanes.
* * * * *
The unsafe condition is the possibility of a dual engine in-flight
shutdown due to LPCV failure. The required actions include retaining
the actions required by AD 2010-14-14, Amendment 39-16359 (75 FR 42585,
July 22, 2010), and include, for certain airplanes, replacing the LPCVs
of LH and RH engines, which would be an option for certain other
airplanes. You may obtain further information by examining the MCAI in
the AD docket.
Relevant Service Information
EMBRAER has issued the following service information, which is
intended to correct the unsafe condition identified in the MCAI.
EMBRAER 170 Maintenance Review Board Report, MRB-1621,
Revision 7, dated November 11, 2010.
EMBRAER Service Bulletin 190LIN-36-0004, dated December
23, 2009.
Changes to AD 2010-14-14, Amendment 39-16359 (75 FR 42585, July 22,
2010)
Paragraphs (j)(11) through (j)(14) of AD 2010-14-14, Amendment 39-
16359 (75 FR 42585, July 22, 2010), have been redesignated as
paragraphs (o)(1) through (o)(4) of this proposed AD.
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.
Costs of Compliance
We estimate that this proposed AD affects 253 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed 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 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);
3. Will not affect intrastate aviation in Alaska; and
4. 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.
