SB No.: 190-36-0023 PAGE: 1 of 1 Copyright © 2014 by Embraer S.A. All rights reserved.PNEUMATIC - REPLACEMENT OF THE LH/RH ENGINE LOW-STAGE BLEED CHECK VALVE PN 1001447-6 In connection with the use of this document, Embraer does not provide any express or implied warranties and expressly disclaims any warranty of merchantability or fitness for a particular purpose. 1. PLANNING INFORMATION A. SB EFFECTIVITY Aircraft affected:
MODEL SN Embraer 190( ) and 195( ) All aircraft in operation equipped with the affected Part Number. NOTE: If the aircraft is already equipped with Black Label 13 software or a later version, and then a new low-stage bleed check valve (zero-hour) PN 1001447-6 is installed, the accomplishment of this SB is not necessary. Affected component: Engine Low-stage bleed check valve PN 1001447-6, all serial numbers, installed on the aircraft. NOTE: This effectivity list includes the aircraft originally equipped with the affected component. Since this component is a Line Replaceable Unit (LRU), it may be necessary to refer to the fleet maintenance control record and verify whether the unit has been replaced with another one during routine maintenance. In-production effectivity: The subject presented in this bulletin does not affect any in-production aircraft. B. CONCURRENT REQUIREMENTS Make sure that Black Label software version 13.0 (SB190-21-0041) or a later version is already installed before the accomplishment of this bulletin.

All rights reserved.NOTE: If the aircraft is already equipped with Black Label 13 software or a later version, and then a new low-stage bleed check valve PN 1001447-6 is installed, the accomplishment of this SB is not necessary. C. REASON (1) HISTORY Embraer has received reports regarding cracks in some engine low-stage bleed check valves PN 1001447-6 recently returned for the periodic Maintenance Review Board (MRB) inspection. Flight and Laboratory Tests have shown that the bleed oscillations during take-off and climb may affect low pressure check valve dynamic behavior and contribute to low-stage bleed check valve petals cracking. It was also observed that Black Label 13 software or a later version prevents this kind of oscilations. Further investigations showed that if a new engine low-stage bleed check valve (zero-hour) PN 1001447-6 is installed in an aircraft already equipped with Black Label 13 software (or a later version) these kind of cracks will not occur. These cracks may lead to low-stage check valve failure and may cause engine shutdown. (2) OBJECTIVE To provide instructions for the replacement of existing low-stage bleed check valves PN 1001447-6 of the LH/RH engine, with a new one bearing the same PN. (3) EXPECTED BENEFITS The actions proposed in this service bulletin are to reduce the risk of in-flight shutdown.
