### TITLE: AUTO FLIGHT - FCC - INSTALL FCC PN B470ADM3 CAPABLE OF RUDDER REVERSAL WARNING. **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR 13591S22844 MINOR None 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 Following report of events of rapid alternating and large rudder pedal inputs that resulted in high vertical stabilizer loads, a new function has been developed in the Flight Control Computer (FCC) to detect excessive pedal reversal inputs in order to trigger visual and aural warnings via Flight Warning Computer (FWC). This Service Bulletin is published to advise all operator of A300-600 aircraft of the issue of THALES AVIONICS S.A. Service Bulletin No. B470ADM-22-006. This Service Bulletin upgrades the two FCC PN B470ADM2 by new FCC PN B470ADM3 capable of rudder reversal warning modified as per instructions given in the THALES AVIONICS S.A. Service Bulletin No. B470ADM-22-006. When Service Bulletin No. A300-22-6054, Service Bulletin No. A300-22-6055, Service Bulletin No. A300-22-6056 and Service Bulletin No. A300-31-6140 are embodied, in case of excessive rudder pedal reversal inputs, visual and aural warnings are triggered in the cockpit: - The FWC provides audio "STOP RUDDER INPUT" messages. - STOP rudder inputs lights are illuminated.
