2012-09-07: We are adopting a new airworthiness directive (AD) for certain Airbus Model A319-111, -112, and -132 airplanes; Model A320-111, -211, -212, -214 and -232 airplanes; and Model A321-111, -211, -212, and -231 airplanes. This AD was prompted by reports that corrosion was found on the overwing refueling aperture on the top wing skin, and that for certain airplanes, repairs made using primer coating may prevent proper electrical bonding provision between the overwing refueling cap adaptor and the wing skin. This AD requires performing an electrical bonding test between the gravity fill re-fuel adaptor and the top skin panels on the left-hand and right-hand wings, and if necessary performing a general visual inspection for corrosion of the component interface and adjacent area, and repairing the gravity fuel adaptor if any corrosion is found. We are issuing this AD to detect and correct corrosion and improper bonding, which in combination with a lightning strike in this area, could create a source of ignition in a fuel tank, resulting in a fire or explosion, and consequent loss of the airplane.

2010-01-04: The FAA is superseding an existing airworthiness directive (AD) for GE CF34-1A, CF34-3A, and CF34-3B series turbofan engines. That AD currently requires removing from service certain part number (P/N) and serial number (S/N) fan blades within compliance times specified in the AD, inspecting the fan blade abradable rub strip on certain engines for wear, inspecting the fan blades on certain engines for cracks, inspecting the aft actuator head hose fitting for correct position, and, if necessary, repositioning the hose fitting. This ad supersedure requires the same actions but corrects the effectivity for certain fan blades requiring corrective actions and changes the effective date of the current AD. This AD supersedure results from the FAA discovering that the existing AD has an incorrect effectivity for certain fan blades requiring corrective actions, and from a report of an under-cowl fire and a failed fan blade. We are issuing this AD to prevent failure of certain P/N and S/N fan blades and aft actuator head hoses, which could result in an under-cowl fire and subsequent damage to the airplane.
