AD FAA-2014-0229

We are adopting a new airworthiness directive (AD) for all Airbus Model A300 and A310 series airplanes, and certain Model A300 B4- 600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). This AD was prompted by a review of certain repairs, which revealed that the structural integrity of the airplane could be negatively affected if those repairs are not re-worked. This AD requires an inspection to identify certain repairs, and corrective action if necessary. We are issuing this AD to detect and correct certain repairs on the floor cross beams flange. If those repairs are not reworked, the structural integrity of the airplane could be negatively affected.
