The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of three units of the MLG Side Brace, identified by NSN 7R-1680-016462303-RQ and reference number 200-5320-001. This procurement requires engineering source approval due to the flight-critical nature of the part, necessitating that only approved sources are solicited to ensure the quality and reliability of the component. Interested vendors must provide comprehensive technical data and documentation as outlined in the NAVSUP WSS Source Approval Information Brochures, with proposals due to the primary contact, Julianna M. Fiandra, at JULIANNA.M.FIANDRA.CIV@US.NAVY.MIL. The timeline for source approval is critical, as delays may affect the ability to meet government requirements.
