The action adds one NSN to an existing long-term sole source contract with Pratt & Whitney (CAGE 52661), under a subsumable contract arrangement. The contract currently has four and a half years remaining plus a possible option of four additional years. It requires supply of parts along with planning/forecasting, inventory management, engineering management, and field engineering support. Delivery terms are FOB Origin with Inspection and Acceptance at Source, and the procurement is unrestricted, but no competitive data package exists. Interested non-OEM sources must provide a complete technical data package and evidence of ability to supply the items for the contract period to be considered.
