This is a procurement for spare parts, specifically an electrical control panel for aircraft anti-collision and landing systems, with a required delivery of 4 units by September 30, 2026. The government intends to solicit and negotiate with only one or a limited number of sources, as the supplies are available from a limited number of responsible sources like the listed qualified source, Bae Systems Controls Inc. The solicitation will be available for download only at www.sam.gov, and proposals received within 45 days of the synopsis publication will be considered. An ombudsman is available to hear concerns from potential offerors during the proposal phase.
