The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of Aileron and similar replacement parts, identified by NSN 7R-1560-016952106-RQ. The procurement involves a quantity of 2 units, with delivery terms set as FOB Origin, and is critical due to the unstable design of the part, which has shown low process yield and marginal performance, necessitating significant changes that may render the current part obsolete. Interested suppliers must be approved by the Government prior to contract award, and those not previously approved must submit detailed technical data and source approval requests alongside their proposals. The Government intends to solicit and negotiate with only one source under FAR 6.302-1, with proposals due within 45 days of the notice publication. For further inquiries, interested parties can contact Alainna M. Pettit at (215) 697-2606 or via email at ALAINNA.PETTIT@NAVY.MIL.
