A -- Implement design change concept to incorporate Beta Cues for E2-C cockpit

The Naval Air Systems Command (NAVAIR) intends to negotiate a modification to a sole source contract with Hamilton Sundstrand, Windsor Locks, CT 06096, to implement a design change concept for an Electronic Propeller Control Software change to incorporate Beta Cues for the Cockpit. Hamilton Sundstrand will also implement a design change concept for a Pump Housing Wiring Change involving the addition of a wire to connect the GFP Pump Housing Assembly’s Reverse Enable Solenoid to a spare pin on the Pump Housing connector. This design shall include drawing changes to the Pump Housing drawing and the propeller installation drawing. Hamilton Sundstrand is the designer, developer, and sole manufacturer of the 54460 and NP2000 propellers and is, therefore, the only source that possesses the resources and in-depth technical knowledge and technical data necessary to provide these services within the time required to meet USN requirements.
