### TITLE: LANDING GEAR - NORMAL BRAKING - INTRODUCE BSCU STD 10.1 - SB ONLY. **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR None MINOR 150040P11402 NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics affecting the airworthiness of the product. All other changes are major changes. REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES On A319/A320/A321 aircraft fitted with Braking and Steering Control Unit (BSCU) standard 10, cases of nose wheel steering loss have been experienced during taxiing at low speed. Further investigation has identified a robustness issue of the monitoring channel law for the elaboration of the rudder steering order. This Service Bulletin recommends upgrading the functional software of the BSCU to the standard 10.1 by reprogramming the On Board Replaceable Modules (OBRMs) 3 of the two systems according to MESSIER-BUGATTI Service Bulletin No. C20216-32-3313. The modification improves the monitoring channel rudder control law to avoid fault code 90 untimely detection, associated with "STEERING ELEC BOX (5GC)" fault message. The operational consequences of this Service Bulletin are the cancellation of Flight Crew Operating Manual (FCOM) Temporary Revision (TR) No. 168. NOTE: For a full improvement description, refer to the Modification Operational Impact (Refer to MOI No. 150040).

(5) Configuration definition **CONF 001 Config. 001 is valid for all the aircraft given in the effectivity of this Service Bulletin as a standard configuration. (6) Material Effectivity MATERIAL QTY PER A/C SEE NOTES Equipment BFEA01 1 B. CONCURRENT REQUIREMENTS Accomplishment of this Service Bulletin requires the prior or simultaneous accomplishment of the following Service Bulletin or the equivalent production modification : Service Bulletin No. A320-32-1336 Mod. No. 36994P8867 A320-32-1360 39773P11295 NOTE: Accomplish either Service Bulletin No. A320-32-1336 or A320-32-1360 as per effectivity specified in these Service Bulletins. C. REASON (1) History On A319/A320/A321 aircraft fitted with Braking and Steering Control Unit (BSCU) standard 10, cases of nose wheel steering loss have been experienced during taxiing at low speed. Further investigation has identified a robustness issue of the monitoring channel law for the elaboration of the rudder steering order. (2) Objective/Action This Service Bulletin recommends upgrading the functional software of the BSCU to the standard 10.1 by reprogramming the On Board Replaceable Modules (OBRMs) 3 of the two systems according to MESSIER-BUGATTI Service Bulletin No. C20216-32-3313. (3) Advantages The modification improves the monitoring channel rudder control law to avoid fault code 90 untimely detection, associated with "STEERING ELEC BOX (5GC)" fault message.
