Airbus SAS Airplanes
This AD applies to Airbus SAS A300 B4-601, A300 B4-603, A300 B4-605R, A300 F4-605R, A310-203, A310-204, A310-304.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300-600 and A310 series airplanes, that requires an inspection to detect defects of the directional pilot valves (DPV); and replacement of any defective DPV with a new DPV, or deactivation of the thrust reverser system, if necessary. This amendment is prompted by a report indicating that, during a maintenance check, an uncommanded deployment and stowage of the thrust reverser occurred due to improperly modified DPV's. The actions specified by this AD are intended to prevent uncommanded deployment and stowage of the thrust reverser during maintenance activities, as a result of improperly modified DPV's, which could result in injury to maintenance personnel or other people on the ground.
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.
