Airworthiness Directive · Amendment 39-12722 · Airbus Model A300 B2 and B4; A300 B4-600, B4-600R, and F4-600R (Collectively Called A300-600); and A310 Series Airplanes
Airbus Model A300 B2 and B4; A300 B4-600, B4-600R, and F4-600R (Collectively Called A300-600); and A310 Series Airplanes
Superseded. A later AD replaced this one: AD 2005-04-11. Comply with the one in force.
All model A300 B2 and B4; A300 B4-600, B4-600R, and F4-600R (collectively called A300-600); and A310 series airplanes; certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to all Airbus Model A300 B2 and B4; A300 B4-600, B4-600R, and F4-600R (collectively called A300-600); and A310 series airplanes. This action requires identification of the part number and serial number of the parking brake operated valve (PBOV); and, if necessary, inspection of the PBOV, including a functional check of the PBOV, and follow-on and corrective actions. This action also provides for optional terminating action for the requirements of this AD. This action is necessary to prevent loss of the yellow hydraulic system, which provides all the hydraulics for certain spoilers; elements of the hydraulics for flaps, stabilizer, pitch and yaw feel systems, pitch and yaw autopilot, and yaw damper; and elevator, rudder, and aileron. This action is intended to address the identified unsafe condition.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
