Airworthiness Directives; Airbus SAS Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A300 series airplanes; 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); and Model A310 series airplanes. This AD was prompted by investigations that found cracks on the main deck cargo door (MDCD) actuator bearing fitting caused by fatigue. This AD requires an operational limitation to the MDCD opening angle, repetitive detailed visual inspection (DET) of the MDCD actuator bearing fittings, and replacement if any cracks are found. The FAA is issuing this AD to address the unsafe condition on these products.
