## Description **Group 1: 1. CONCURRENT REQUIREMENTS**  None. **2. BACKGROUND** This service bulletin provides instructions to replace the Ram Air Turbine (RAT) Pump and Control ModuleAssembly to prevent failure of the hydraulic pump at low air speed. The RAT Assembly provides an emergency source of electrical and hydraulic power for the primary flight control if the left, center and right main hydraulic systems fail. Loss of the RAT Pump and Control Module Assembly could lead to loss of control of the airplane when emergency power from RAT Assembly is needed. If this change is not incorporated on the RAT Assembly and hydraulic power is lost on the left, right and center main hydraulic systems, then the RAT Assembly may not provide sufficient hydraulic power which could result in the loss of many critical control systems that are necessary for safe flight. The supplier discovered that the RAT Assembly may fail at low airspeeds. The volume fuse on the RAT Assembly may be accidentally activated in flight before the RAT is deployed. This may lead to improper pump offloading when the RAT is needed. Testing from supplier concludes such issues could possibly occur at airspeed below 180 knots equivalent airspeed. The new RAT Pump and Control Module Assembly includesan updated volume fuse design. Incorporation of this service bulletin will improve reliability of the RAT Assembly.
