repeat the insulation resistance test.

              4.        If, as a result of the Requirement 2 test, all resistance measurements are found to be greater than one megohm (1 M), but one or more resistance measurements are less than five megohms (5 M) either:

                  1. repeat the Requirement 1 visual inspection, or

b.         replace the fuel pump with a new or serviceable fuel pump in accordance SB 747-28A2194 Rev 1 and repeat the insulation resistance test.

              5.        If any discrepancy is noted during the Requirement 1 visual inspection, replace the fuel pump with a new or serviceable fuel pump in accordance SB 747- 28A2194 Rev 1 and perform the Requirement 2 insulation resistance test.

           Note 2: FAA AD 97-03-17 Amdt 39-9922 together with FAA AMOC Letters 140S-02- 156, 130S-02-253 and 140S-02-191 refer.

           Compliance: For Requirement 1 - Remains unchanged as "Prior to 14 July 1997 and thereafter at intervals not exceeding 5000 hours time in service (TIS) or 18 months, whichever occurs first".

           Repetitive visual inspections may be terminated if any of the conditions specified in Requirement 1.a., 1.b. or 1.c. are met.

           For Requirement 2 - Prior to further flight immediately following the Requirement 1 visual inspection.

           For Requirement 3 - Prior to further flight immediately following the Requirement 2 insulation resistance test.

           For Requirement 4.a - Within 500 hours TIS after the Requirement 2 insulation resistance test.

           For Requirement 4.b - Prior to further flight immediately following the Requirement 2 insulation resistance test.

           For Requirement 5 - Prior to further flight immediately following the Requirement 1 visual inspection.

           This Amendment becomes effective on 8 August 2002.

           Background: The original issue of this Directive followed advice from Boeing that operators have reported fuel leaks at the boost and override/jettison fuel pumps. The actions mandated by the initial issue of the Directive were designed to provide early detection of fuel leaks preventing the likelihood of fire in the vicinity of the affected pump.

           This Amendment introduces optional terminating actions for the Requirement 1 repetitive inspections.

           The original issue of this Airworthiness Directive became effective on 27 March 1997.
