The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure a conduit fan for aircraft, identified by NSN 7R-5975-014650295-EL. The procurement requires that the part be sourced from approved suppliers as it is flight critical, and suitable technical data or manufacturing knowledge is not available for alternative sources. Interested vendors must provide necessary documentation for source approval along with their proposals, as the government intends to negotiate with only one source under FAR 6.302-1. Proposals must be submitted within 45 days of the notice, and interested parties can contact Jena Visconto at JENA.VISCONTO@NAVY.MIL for further information.
