configuration `D' switch master module and the switch P/N is not specified Table 1, carry out either of the following and do the part number revision in accordance with Requirement 3.c:

        a. Replace the switch with a switch specified in Table 1, in accordance with ASB 747-33A2280, Revision 1, except as provided by Requirement 4.
        b. Replace the switch master module with a new configuration `D' master module in accordance with ASB 747-33A2280, Revision 1.
        c. If all switches on a panel assembly have a configuration `D' master module or have a switch P/N specified Table 1 revise the P/N of the panel assembly in accordance with ASB 747-33A2280, Revision 1.
   Table 1
   Boeing P/N S231T290-4201 through -4325 inclusive,
   Korry P/N 4336731004-4201 through -4325 inclusive, or
   switches that have a configuration `D' master module.
   Note 3:  One-to-one switch correlation between the existing switches and the new part number switches can be found in Korry SB 433-33-06, dated 7 November 2001.
      4. If, during any Requirement 1.a. inspection, a configuration `D' switch master module is found or the P/N is specified in Table 1 on all switches for a panel assembly, revise the part number of the panel assembly, in accordance with ASB 747-33A2280, Revision 1.
      5. If any panel assemblies, switches or master modules are replaced during any action required by this Directive, carry out all applicable operational tests in accordance with ASB 747-33A2280, Revision 1, except as provided by Requirement 6.
      6. Where paragraph 3.B.14.b.(3) of the Accomplishment Instructions of ASB
      747-33A2280, Revision 1 specifies procedures to do a test of the engine ignition control/fuel jettison module assembly, this Directive requires that operators
      dry-motor the engine to remove the fuel from the tailpipe before doing the procedures in paragraph 3.B.14.b.(3).  All fuel must be removed from the engine tailpipe before performing the test, because during the test the engine igniter will be energized.
   Note 4:  ASB 747-33A2280, Revision 1 refers to the Boeing component service bulletins specified in Table 2 of this Directive as additional sources of service information for replacing the switch or switch master module at critical locations, for doing operational tests after the replacement, and for identifying new panel part numbers.
