| Background: | During a routine inspection on an A321 aircraft, the operator discovered that a bearing of the flap track No. 1 pendulum assembly had migrated out of position. An investigation has revealed that the pendulum bearing migration was probably due to the methods used during an in-service replacement of the bearing during maintenance. This Directive requires a one-time inspection of the affected flap track No.1 pendulum assembly, and if bearing migration is evident, replacement of the affected flap track pendulum assembly. |
