nonrotating parts have the potential to create an ignition source in the form of hot surfaces or sparks.  In addition, during dry operation of the pumps, ignition of vapour in a fuel pump can create a flame front that can reach the fuel tank and cause a fuel tank explosion.

   This Directive is issued to prevent ignition of fuel vapours due to the generation of sparks and a potential ignition source inside the centre tank caused by metal-to-metal contact during dry fuel pump operation, which could result in a fire or explosion of the fuel tank.  This Directive requires revising the AFM to prohibit extended dry operation of the centre tank fuel pumps.

   This amendment deletes the original text of the AD and incorporates the original FAA AD by reference.  This was done to facilitate easier cross referencing to FAA AD 2011-18-03 Amdt 39-16785 which details the terminating action for the requirement of this AD.

   The original issue of this AD became effective on 10 May 2001.

   Alternative Methods of Compliance for AD 2001-08-24 Amdt 39-12201 that are approved by the FAA are acceptable as a means of compliance against this AD.
