change and the Requirement 2 placard.
             Later revisions of the above SB(s), approved by the United States Federal Aviation Administration (FAA) as an Alternate Method of Compliance (AMOC) to FAA AD 2006-05-08, are considered acceptable for compliance with the equivalent Requirements of this Directive.
             Note 3:  FAA AD 2006-06-03 Amdt 39-14511 refers.
Compliance:  For Requirements 1 and 2 - Within 25 hours time in service (TIS) after the effective date of this Directive.
             For Requirement 3 - Within 300 hours TIS after the effective date of this Directive.
             For Requirement 4 - Before further flight, immediately following the Requirement 3.a. inspection.
             For Requirement 5 - Before further flight after the Requirement 3 inspection and modification are accomplished.
             This Airworthiness Directive becomes effective on 15 June 2007.
Background:  This Directive requires the revision of the AFM to initially prohibit use of the wing fuel boost pumps for defueling under certain conditions and the installation of a placard.  The Directive subsequently requires the accomplishment of other specified investigative and corrective actions as necessary.  Terminating action for this Directive is the modification of the wing boost pumps together with the removal of the AFM revision and placard.
             The FAA has received a report of a chafed electrical wiring harness, which was arcing inside the fuel tank.  This Directive is issued to prevent potential fuel vapour ignition in a fuel tank, which could result in explosion and loss of the aeroplane.
