The FAA is adopting a new airworthiness directive (AD) for certain Airbus airplane models, as specified above. This AD requires installing electro-pneumatic locking bar devices (TRAS lock systems) in the engine nacelles, installing a dedicated and shielded electrical circuit that is segregated from the existing thrust reverser control system, and performing related investigative/corrective actions if necessary. This AD results from the manufacturer's reassessment of the thrust reverser systems in the Airbus airplane models specified above, which showed that the thrust reverser could inadvertently deploy in flight under certain conditions. We are issuing this AD to prevent inadvertent deployment of thrust reversers in flight, which could result in reduced controllability of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
For airplanes identified in the service bulletins specified in Table 3 of this AD: Within 36 months after the effective date of this AD, install the electro-pneumatic locking bar devices (TRAS Lock Systems) in the thrust reverser system of the nacelles, in accordance with the Accomplishment Instructions of the applicable service bulletin.

(g) For airplanes identified in the service bulletins specified in Table 4 of this AD: Prior to or concurrent with the accomplishment of the applicable service bulletin specified in paragraph (f) of this AD, accomplish all the modifications and actions related to an independent third line of defense on the thrust reversers, in accordance with the Accomplishment Instructions of the applicable service bulletin specified in Table 4 of this AD.
