must be accomplished either in conjunction with or after the accomplishment of this

bulletin.

C. REASON

(1) HISTORY

The Air Management System (AMS) processor board manufacturer has released a

new operational program software version to eliminate the possibility of right hand

(RH) engine compressor stall after the Auxiliary Power Unit (APU) becomes the

active bleed source for the left side.

In addition, the new software includes improvements and corrections for AMS

system control logic and built-in test functions.

The Air Management System (AMS) controller operational program software is also

known as the Black Label - BL.

(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-11.0.

(3) EXPECTED BENEFITS

The purpose of this software change is to correct the issues presented in the Air

Management System control logic, its built-in test, and the fault monitoring functions

at the field operation. The occurrence of spurious fault messages will also be

reduced, so that the maintenance actions will be facilitated.

(4) REVISION HISTORY

None.

D. DESCRIPTION

This Service Bulletin presents Hamilton Sundstrand SB 1001050-21-10, dated Nov

23/2010, which provides instructions for replacing the Hamilton Sundstrand AMS

Controller Operational Program of the AMS controller processor boards with a new

improved one.

To do the modification described above, the operator has three alternatives, as follows:

(1) The AMS controller processor boards can be programmed on-wing as a line

maintenance activity by referring to the Aircraft Maintenance Manual procedures or

to the paragraph 3.C.(3) Accomplishment Instructions of Hamilton Sundstrand SB

1001050-21-10, attached to Section 4. APPENDIX 1 of this bulletin. For this,

operators may optionally call for Hamilton Sundstrand (HS) trained personnel to

assist the on-wing modification. For this, contact a local Hamilton Sundstrand

technical representative, or

(2) The AMS controller processor boards can be programmed off-wing, referring to the

Aircraft Maintenance Manual procedures or to the paragraph 3.C.(1)

Accomplishment Instructions of Hamilton Sundstrand SB 1001050-21-10, attached

to Section 4. APPENDIX 1 of this bulletin. For this, operators may optionally call for

Hamilton Sundstrand (HS) trained personnel to assist the off-wing modification. For

this, contact a local Hamilton Sundstrand technical representative, or

(3) The AMS processor boards can be removed from the Secondary Power Distribution

Assembly (SPDA) 2 and returned to a Hamilton Sundstrand approved component

repair station and programmed by referring to the Component Maintenance Manual

procedures.

To do all the above mentioned alternatives, it is necessary to gain access to the middle

avionics compartment by opening access doors 199BL, 147AL, and 123BL.

NOTE: The modification presented in this bulletin does not affect Fatigue Critical

Structure (FCS).

Use or disclosure of this data is subject to restrictions on the front page of this document.

(1) For the upgrade of AMS software installed on EMB170/190 aircraft to black label 

11.0

All AMS controller processor boards Identified as Hamilton Sundstrand Part 

Numbers 1001050-1-YYY, 1001050-2-YYY, 1001050-3-YYY and, 1001050-4-YYY. 

YYY identifies any prior software configuration.

NOTE: Part numbers 1001050-3-YYY and 1001050-4-YYY Identify processor 

cards which incorporate the modification defined in Hamilton 

Sundstrand Service Bulletin 1001050-21-06.

NOTE: The AMS controller black label 11.0 software version introduced by this 

service bulletin contains all software improvements contained in the 

previous AMS controller software versions.

B. Concurrent Requirements

(1) Not applicable

C. Reason

(1) The software configuration introduced by this Service Bulletin was generated to 

incorporate AMS controller software improvements. The new software includes 

improvements and corrections for AMS system control logic and built in test 

functions.

(a) The following software improvements will be incorporated when upgrading to 

AMS software change black label 11.0:

1 Revised APU bleed request logic to prevent the APU shutoff valve from 

opening before the cross bleed valve has closed. This change is 

implemented to prevent the possibility of a right engine shutdown caused by 

the APU bleed flow back pressuring the right engine during bleed source 

transitions when the right engine is supplying bleed air. As part of this change 

the LH (left hand) NAPRSOV control logic was modified to further protect 

against uncommanded left engine shutdown.

2 Remove indication that SAIV IBIT is not active and remove its use in logic to 

close both NaPRSOVs. Although the SAIV IBIT is no longer automatically 

commanded on ground after landing, this monitor is already considered in the 

logic that commands both NaPRSOVs to close (BLK 10.1 and previous 

versions), delaying the bleed source transition.

3 Revised HPSOV built in test logic to eliminate spurious HPSOV faults 

occurring during single bleed - dual pack operating conditions on aircraft with 

AMS software BLK 9.0. 

4 Revised Initiated built in test logic for the Add Heat Valve (AHV) to prevent 

spurious faults occurring on aircraft with AMS software BLK 9.0. As part of 

this change the existing AHV Failed Open and Failed Closed CMC messages 

were replaced with a single AHV Failed CMC Message. The AHV failed open 

fault was also removed from the PACK 1 (2) FAIL CAS message setting logic. 

In Black Label 10.1 the AHV maintenance messages were inhibited as an 

interim solution.

5 Revised built in test logic for the Low Limit Valve for improved fault detection 

capability. Improved logic will help to prevent spurious faults occurring during 

transient pack operating conditions.

6 Revised the RH Pack Bypass Valve Failed Open fault logic to prevent 

spurious faults occurring on aircraft with AMS software BLK 9.0 and above.

7 Revised SPDA / AMS Controller ARINC communication built in test logic to 

prevent spurious ARINC faults occurring during power up transients. As part 

of this change the RECIRC SMOKE DET FAIL CAS message logic was 

revised to prevent spurious CAS messages triggered by the ARINC built in 

test monitor.
