           Requirement: Action in accordance with BAe Systems Mandatory Service Bulletin (SB) 54-010 Revision 1 or SB 54-010 Revision 2.

              Compliance: For aircraft that have achieved 4 years total time in service: Before accumulating 2,000 flights after 15 June 2000.

           Background: The manufacturer received reports of in-service failures of engine pylon to wing forward attachment bolts. Investigation revealed the failures were due to corrosion in the bolt head undercut.

           Amendment 2 introduced to the accomplishment instructions an alternative method to re-protect bolt non-threaded areas previously cadmium plated.

           Amendment 3 is issued to re- instate SB 54-010 Revision 1 as an equivalent Requirement document of this Directive.
