NAWCAD Lakehurst, NJ intends to award a firm-fixed-price, sole-source contract to The Rhinestahl Corporation for two Support Rail Engine Adapters, P/N 21C14050G03, in support of the F/A-18. The action is justified under FAR 6.302-1 and 10 U.S.C. 3204(a)(1) because only one responsible source can satisfy the requirement. This is not a request for competitive proposals, though the Government will consider responses and may use them to determine whether to conduct a competitive procurement. SAM registration is mandatory for consideration, and the requirement is managed by NAWCAD LKE in Lakehurst, NJ.
