This is a Sources Sought notice for a sole-source, fixed-price contract to purchase a specific titanium hydraulic tube repair set (P/N: DAT02AEFKT4024) from Permaswage USA and its authorized distributors. The item will support CH-53K aircraft maintenance for both the NAVAIR program and an Israel Foreign Military Sales program. The justification is that Permaswage USA is the proprietary designer and sole manufacturer of this part, and the government lacks the technical data to obtain it elsewhere. No budget, performance location, or non-bid/proposal timelines are specified in this description. The notice explicitly states it is not a request for competitive proposals.
