The FAA is adopting a new airworthiness directive (AD) for certain Airbus airplanes, listed above. This AD requires installing two-stage relays in the electronics rack (90VU), and performing related corrective and investigative actions. This AD results from reports of inadvertent rudder trim activation when the autopilot is on. We are issuing this AD to prevent inadvertent trim activation when the autopilot is on and the slats are extended, which could result in rudder activation when the autopilot is turned off.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 16 months after the effective date of this AD: Install two-stage relays in the electronics rack 90VU between switch 4CG and relays 12CG and 13CG; and do any applicable related corrective and investigative actions before further flight. Do all the actions in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-27-6031, Revision 03, dated February 9, 2001 (for Model A300-600 series airplanes); or Airbus Service Bulletin A310-27-2077, Revision 03, dated February 9, 2001 (for Model A310 series airplanes).
Installations are also acceptable for compliance with the requirements of paragraph (f) of this AD if done before the effective date of this AD in accordance with one of the service bulletins identified in Table 2 of this AD.
