## Affected component: AMS controller processor boards PN prefix 1001050, with any previously released Black Label version, installed on the aircraft and in stock as spare. 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 the routine maintenance.

## SB No.: 190-21-0041 PAGE: 1 of 44 Copyright © 2013 by Embraer S.A. All rights reserved.

## Embraer 19 0 ( ) and 195 ( ) model aircraft SN 19000587, SN 19000589, and 19000593 and on, have an equivalent modification factory-incorporated. B. CONCURRENT REQUIREMENTS None.
C. REASON (1) HISTORY After the introduction of the Nacelle Pressure Regulating Shutoff Valve (NAPRSOV) PN 1013952-1 in the fleet, some bleed oscillations events during take-off/climb phases at high engine power thrust have been observed. Embraer engineering analysis revealed that this NAPRSOV PN 1013952-1 inconjunction with some other degraded components make the system more susceptible to this kind of oscillations. Therefore, Embraer and Hamilton Sundstrand developed a new Black Label software version 13.0 in order to prevent new occurrences of these events. In addition, this new software version also addresses two Air Cycle Machine (ACM) failure modes: rotor speed excursions on ground and heat exchanger blockage during single bleed operation. Both are key contributors of ACM fan and bearing failures. (2) OBJECTIVE This bulletin gives instructions for the Air Management System (AMS) controller operational program software upgrade, from any of the previous versions to BL-13.0. (3) EXPECTED BENEFITS The modification presented in this Service Bulletin is aimed at preventing events of bleed oscillations in the fleet during take-off/climb phases at high engine power thrust, as well as to improve Air Cycle Machine (ACM) reliability.

# SERVICE BULLETIN Hamilton Sundstrand Corporation, a UTC Ae rospace Systems Company

UTC AEROSPACE SYSTEMS PROPRIETARY - Subject to the restriction on the title or cover page. Subject to the EAR - See the Title, First, or Cover Page for more information. 1. PLANNING INFORMATION A. Effectivity (1) For the upgrade of AMS software installed on EMB170/190 aircraft to black label 13.0 All AMS controller processor boards Identified as Hamilton Sundstrand Part Numbers 1001050-1-YYY, 1001050-2-YYY, 1001050-3-YYY, 1001050-4-YYY, 1001050-5-YYY, 1001050-6-YYY, 1001050-7-YYY. Where YYY identifies any prior software configuration NOTE: The AMS controller black label 13.0 software version introduced by this service bulletin contains all software improvements contained in the previous AMS controller software versions. B. Concurrent Requirements (1) None C. Reason (1) The software configuration introduced by this Service Bulletin was generated to incorporate AMS controller software improvements. The following software improvements will be incorporated when upgrading to AMS software change black label 13.0 (a) Pneumatic bleed system control and built in test improvements: 1 Revised engine bleed system control logic to quickly detect manifold pressure oscillations and respond by implementing an override command to the bleed valve (open loop logic) to stabilize manifold pressure. (Applicable to EMB190/195 only). 2 Revised engine bleed system control logic to de-activate the engine bleed system and open the cross bleed valve if the corresponding air conditioning pack is on MEL (de-activated). This change will reduce manifold pressure oscillations on the side where no bleed flow is being utilized. 3 Revised BLEED OFF EICAS setting logic so the message is only displayed during failure / abnormal operating conditions or when the system is shutdown by the pilot. 4 Revised HPSOV failed closed fault logic to require a higher pressure drop across the HPSOV before the fault is set. This improvement will help to eliminate spurious HPSOV failed closed faults. (b) Air conditioning system control and built in test improvements: 1 Revised ventilation control logic to reduce the pack flow reference on the ground during engine idle conditions. These changes are implemented to prevent an ACM over-speed condition which can result from the flow control valves being commanded full open during taxi/takeoff.

(2) The modification procedures in this Service Bulletin may also be performed using alternate software loading procedures, which are defined in this Service Bulletin. The alternate loading procedures in this service bulletin include procedures for loading the AMS Processor cards “off wing” (using a GSE holding fixture) and loading the AMS processor cards “on wing”. Instructions for performing these loading procedures are as follows: (a) Procedure for off-wing loading of AMS Controller Processor board software. Refer to Figure 1

. WARNING: MAKE SURE THAT THE AIRCRAFT IS IN A SAFE CONDITION BEFORE YOU DO THE MAINTENANCE PROCEDURES. THIS IS TO PREVENT INJURY TO PERSONS AND/OR DAMAGE TO THE EQUIPMENT. 1 Do the procedure to make the aircraft safe for maintenance (AMM TASK 20- 00-00-910-801-A/200). 2 Select the applicable cables, interface devices, power supply, and laptop of AGE16695, AGE14573 and AGE16732 related to the AMS controller software-loading application. 3 Remove the AMS Controller Processor Modules (slots 18 and 25) from the aircraft (AMM TASK 21- 00-01-000-801-A/400), as applicable. CAUTION: THE MODULE OR UNIT CONTAINS ELECTROSTATIC DISCHARGE SENSITIVE (ESDS) ITEMS. OBEY THE APPROVED INDUSTRY PRECAUTIONS WHEN YOU TOUCH, REMOVE, OR INSERT PARTS OR ASSEMBLIES. DAMAGE CAN OCCUR FROM ELECTROSTATIC DISCHARGE. 4 Obey all the electrostatic discharge safety precautions (AMM TASK 20-40- 00-910-801-A/200). 5 Connect the DC power supply (12) to the card chassis AGE14573 (1) and install its ground strap.
