in accordance with Boeing Alert Service Bulletin 767-28A0050, dated 18 December 1997; or Boeing SB 767-28A0050, Revision 1, dated 22 December 1999; terminates Requirement 1, 2 and 3 of this Directive, except as provided by Requirements 4 and 5 of this Directive.
                4. For any aeroplane on which the centre fuel tank is reactivated, the centre fuel tank must be reactivated in accordance with a method approved by the Manager, Continuing Airworthiness, Airworthiness and Engineering Branch, Civil Aviation Safety Authority.  For a reactivation method to be approved, the reactivation method must meet the certification basis of the aeroplane, and the approval must specifically reference either this Directive or FAA AD
                2009-16-06.
                5. For any aeroplane on which the centre fuel tank is reactivated, Requirements 1, 2 and 3 of this Directive must be accomplished.
             Later revisions of SB 767-28A0083, Revision 2, or 767-28A0084, Revision 1 approved by the United States Federal Aviation Administration (FAA) as an Alternate Method of Compliance (AMOC) to FAA AD 2009-16-06, are considered acceptable for compliance with the equivalent Requirements of this Directive.
             Note 3:  FAA AD 2009-16-06 Amdt 39-15989 refers.
Compliance:  For Requirement 1 - Within 36 months after the effective date of this Directive.
             For Requirement 2 - Concurrently with Requirement 1.
             For Requirement 3 - Within 30 days after the effective date of this Directive.
             For Requirement 4 - Prior to tank reactivation.
             For Requirement 5 - Before further flight following the reactivation, or within 36 months after the effective date of this Directive, whichever occurs later.
             This Airworthiness Directive becomes effective on 24 September 2009.
Background:  This Directive results from a design review of the fuel tank systems.  The Directive is issued to prevent an overheat condition outside the centre tank fuel pump explosion-resistance area that is open to the pump inlet, which could cause an ignition source for the fuel vapours in the fuel tank and result in fuel tank explosions and consequent loss of the aeroplane.

   The Directive requires installing an automatic shutoff system for the auxiliary fuel tank override/jettison fuel pumps (also referred to as centre tank fuel pumps in the AFM), revising the AFM to advise the flightcrew of certain operating restrictions for aeroplanes equipped with an automatic auxiliary fuel tank pump shutoff control and, for certain aeroplanes, installing a placard to alert the flightcrew of certain fuel usage restrictions.  The Directive also provides optional terminating actions for certain requirements.
