The Department of Defense, through the Defense Logistics Agency (DLA) Aviation at Philadelphia, PA, is seeking proposals for the procurement of 17 units of the Shock Strut Assembly, identified by NSN 7R-1560-014063444-EL. This procurement requires engineering source approval from the design control activity to ensure the quality of the part, as it is flight critical and the technical data available does not support full and open competition. Interested suppliers must be approved sources or provide detailed documentation for source approval, as outlined in the NAVSUP Weapon Systems Support Source Approval Information Brochures. Proposals must be submitted within 45 days of this notice, and interested parties can contact Michael Kneble at (215) 737-5619 or via email at MICHAEL.KNEBLE@DLA.MIL for further information.
