Airworthiness Directives; Airbus Model A310 Series Airplanes; and Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model C4 605R Variant F Airplanes (Collectively Called A300-600)

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A310 series airplanes; and Model A300 B4-600, B4- 600R, and F4-600R series airplanes, and Model C4 605R Variant F airplanes (collectively called A300-600). This AD requires one-time general visual, detailed, and tap test inspections for discrepancies in the structural integrity of the rudder and its attachments, and corrective actions if necessary. This AD is prompted by a report that, during cruise, a Model A310 series airplane lost most of its rudder, which was made from composite-fiber-reinforced plastic. Investigation revealed that most of the rudder, including the front spar portion above the three servo control actuators was missing. We are issuing this AD to prevent detachment of the rudder from the airplane, which could degrade airplane handling qualities and result in reduced controllability of the airplane.
