Boeing fuel pump AD expanded

 - May 6, 2008, 8:57 AM

Boeing Business Jets are included in a new AD that expands the provisions of an August 30 emergency AD concerning possible exposed wires in fuel pumps that, in combination with a volatile air/fuel vapor mix in a partially filled fuel tank, could cause an explosion. The original AD applied to 118 new-generation 737s and some 747s and 757s, but because more pumps than originally discovered might have problems, the new AD applies to all 3,200 of these types. X-ray inspections are required and, until corrective action is available, minimum fuel quantities must be followed to ensure that the center-wing fuel pump inlets are covered with fuel when the pump is on.
