| This Airworthiness Directive becomes effective on 27 August 2009. | |
| Background: | Reports were received of sensor strut corrosion and the attachment bolt sheared. Investigation revealed that the corrosion was due to the wear of the protective surface, and the attachment bolt sheared due to fatigue rupture subsequent to an increase of the axial loads. This situation could lead to total loss of the sensor strut function resulting in the inability to detect disconnection at tracks 4 and 5 which, in the worst case, could lead to separation of the outboard flap. |
