The Defense Logistics Agency at Redstone Arsenal, Alabama, is conducting market research to identify potential manufacturing/supply sources for a sole-source acquisition of one NSN (1650-01-312-2980; part 114H6801-5, Cylinder Assembly, A) supporting the CH-47 Chinook helicopter under NAICS 336413. The data needed for competitive acquisition is unavailable, so the effort is currently being pursued under FAR 6.302-1 as an only-one-responsible-source requirement. All business types are invited to identify themselves, but contractors must meet prequalification requirements and are encouraged to seek source approval for future solicitations. The contractor would be responsible for becoming a qualified source, including recurring and nonrecurring engineering, and for all manufacturing/production aspects such as supply chain management, logistics, forecasting, long-lead procurement, obsolescence, and final delivery. This announcement is for informational and planning purposes only, does not constitute a solicitation or commitment, and no funds are available to pay for response preparation.
