| Background: | At the initial issue of BAE Systems (operations) Ltd Inspection Service Bulletin (ISB) 57-a071, which was mandated by EASA AD 2006-0091-E, inspection for possible cracks were required on the wing top skin under the rib 0 joint strap. This ISB has now been revised, adding specific instructions for aircraft which have embodied a centre wing overwing refuel aperture repair. Changes consist of a revision of Appendix 1 (ultrasonic inspection) to define the extent of wing top skin inspection and the inclusion of Appendix 2 (radiographic inspection) to inspect further areas of the wing top skin at the outboard fastener row overlapped by the repair plate. |
| The original issue of this AD became effective on 26 April 2006. |
