The Department of Defense, specifically the NAVSUP Weapon Systems Support, is seeking to procure the repair of an Inboard Retention Plate, part number 70358-06612-042, on a sole source basis from Sikorsky. The procurement involves a quantity of one unit, and the government has indicated that no drawings or data are available for this part, as they do not own the necessary rights to purchase it from other sources. This component is critical for helicopter rotor blades and drive mechanisms, underscoring its importance in maintaining operational readiness. Interested parties must submit their capability statements or proposals within 35 days of this notice to Kate N. Schalck at kate.n.schalck.civ@us.navy.mil, as the solicitation will be conducted electronically and will not be open for competitive proposals.
