AD NUMBER: 2008-22-01
MANUFACTURER: Boeing,Bombardier,McDonnell Douglas
SUBJECT: Airworthiness Directive 2008-22-01
SUMMARY: We are adopting a new airworthiness directive
(AD) for various transport category airplanes.
This AD requires deactivation of PATS Aircraft, LLC, auxiliary
fuel tanks. This AD results from fuel system reviews conducted by
the manufacturer, which identified unsafe conditions for which the
manufacturer has not provided corrective actions.
We are issuing this AD to prevent the potential of ignition
sources inside fuel tanks, which, in combination with flammable
fuel vapors, could result in fuel tank explosions and consequent
loss of the airplane.
