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.

(d) Subject

    Air Transport Association (ATA) of America Code 36, Pneumatic.

(e) Reason

    This AD was prompted by 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. We are issuing 
this AD to prevent the possibility of a dual engine in-flight 
shutdown due to LPCV failure.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

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

    This paragraph restates the requirements of paragraph (f) of AD 
2010-14-14, Amendment 39-16359 (75 FR 42585, July 22, 2010). For 
Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU airplanes 
equipped with LPCVs having P/N 1001447-3: Within 100 flight hours 
after November 29, 2005 (the effective date of AD 2005-23-14, 
Amendment 39-14372 (70 FR 69075, November 14, 2005)), 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

effective date of AD 2010-14-14, Amendment 39-16359 (75 FR 42585, 
July 22, 2010)), no person may install any LPCV identified in 
paragraph (k)(4)(i) or (k)(4)(ii) of this AD on any airplane.
    (i) Any LPCV having P/N 1001447-3, installed on Model ERJ-170 
airplanes, that has accumulated more than 3,000 total flight hours.
    (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 a 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
