All other changes are major changes. REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES New software standard L19 on Flight Control Primary Computer (FCPC) 2K2 hardware was defined in order to take into account the last FCPC software evolutions. This Service Bulletin is published to advise all operators of A340 aircraft of the issue of AIRBUS FRANCE S.A.S..LA2K2-27-008. This Service Bulletin consists in introducing new software standard "L19" on FCPC hardware 2K2 by means of On Board Replaceable Module (OBRM) on the three FCPCs. Accomplishment of this Service Bulletin introduces the following modifications: - New elevator position monitoring, - Improvement of the monitoring of the Flight Control Computer pushbutton switches, - Improvement of monitoring to detect a Trimmable Horizontal Stabilizer Actuator (THSA) manual command jamming, - Improvement of the double pressurization logic on elevator, - New monitoring to avoid mixability between FCPC different standards,
