Unsafe condition
This AD was prompted by fuel system reviews conducted by the manufacturer, and our determination that additional actions are necessary to address the identified unsafe condition. We are issuing this AD to reduce the potential of ignition sources inside fuel tanks in the event of a severe lightning strike, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
Affected ADs
This AD supersedes AD 2009-26-17, Amendment 39-16156 (74 FR 69268, December 31, 2009).
