station door; and install an 'INOP' placard on the fuelling panel.
                     or

                        ii. Cutting, stowing and splicing the two wires for the float switch at the splices on the front spar.  Then paint a 'Caution' that shows a conservative maximum fuel capacity for the centre tank on the underside of the right-hand wing near the fuelling station door.

                   or

                     c. Accomplish the inspection and modification of the pressure fuelling system in accordance with Boeing ASB 737-28A1141 Revision 3 dated 9 December 2005.

                Note 3:  Accomplish the requirements specified in either 1.b.i. or 1.b.ii., in accordance with Part 2 of the Accomplishment Instructions of Boeing ASB 737-28A1132 or Revision 1 or Revision 2.

                   2. If no discrepancy is detected during the Requirement 1.a. inspection, carry out either of the following:

                     a. Measure the resistance between the wires and the float switch housing, in accordance with the ASB 737-28A1132 or Revision 1 or Revision 2.

                    or

                     b. Replace the float switch and wiring with a new float switch and wiring, and install double Teflon sleeving over the wiring of the float switch, in accordance with the ASB; or replace the float switch and wiring with a new, improved float switch and wiring in accordance with the Accomplishment Instructions of Boeing ASB 737-28A1141 Revision 3, except, if the replacement float switch and wiring are not available, accomplish Requirements 1.b. and 10.

                Note 4:  After the effective date of this Directive only a new, improved float switch and wiring may be installed.

                   3. If the resistance measured at Requirement at 2.a. is less than 200 megohms , replace the float switch with a new float switch, and install double Teflon sleeving over the wiring of the float switch and wiring, in accordance with the ASB 737-28A1132 or Revision 1 or Revision 2; or replace the float switch and wiring with a new, improved float switch and wiring in accordance with the Accomplishment Instructions of Boeing ASB 737-28A1141 Revision 3; except, if the replacement float switch and wiring are not available, accomplish Requirements 1.b. and 10.
                   4. If the resistance measured at Requirement at 2.a. is greater than or equal to 200 , blow dirt out of the conduit, install double Teflon sleeving over the wiring of the float switch, and reinstall the existing float switch, in accordance with the ASB 737-28A1132 or Revision 1 or Revision 2.

                   5. If, during the Requirement 1.a. inspection, any worn insulation is detected, but no copper conductor is exposed, and evidence of arcing is not detected; accomplish either Requirement 2.a. or 2.b.

                   6. If, during the Requirement 1.a. inspection, any electrical arcing or exposed copper conductor is detected, carry out either of the following:

                     a. replace any section
