257U0002-32-04, including Appendix A  19 December 2001                                                                                                                                                                                                                                                                                                                                                                                            Landing Gear Actuator Control Lever Module Assembly
                                      Actions accomplished before the effective date of this Directive in accordance with Boeing ASB 747-33A2280 dated 19 December 2001, are considered acceptable for compliance with the corresponding action specified in this Directive, provided that the actions specified in this Directive are done on the switches for the additional panel assemblies specified in Revision 1 of the service bulletin.
                                      Later revisions of the above Boeing SBs, approved by the United States Federal Aviation Administration (FAA) as an Alternate Method of Compliance (AMOC) to FAA AD 2008-02-14, are considered acceptable for compliance with the equivalent Requirements of this Directive.
                                      Note 5:  FAA AD 2008-02-14 Amdt 39-15344 refers.
Compliance:                           For Requirements 1 and 2 - Within 60 months after the effective date of this Directive.
                                      For Requirement 3, 4 and 5 - Before further flight after the Requirement 1.a. inspection.

             For Requirement 6 - Before carrying out a test of the engine ignition control/fuel jettison module assembly in accordance with Requirement 5.
             This Airworthiness Directive becomes effective on 10 April 2008.
Background:  The FAA has received a report indicating that the integrated drive generator failed in flight due to a possible switch malfunction.  This Directive is issued to ensure that certain lighted pushbutton switches in the flight compartment do not malfunction and cause the flightcrew to be unable to control critical systems and continue safe operation of the aeroplane.
             The Directive requires an inspection of certain lighted pushbutton switches in the flight compartment for configuration `D' master modules and part numbers together with any necessary corrective action.  The Directive also provides an option to inspect panel assemblies for part numbers.
