The Department of Defense, through the Defense Logistics Agency (DLA) Aviation at Philadelphia, PA, is seeking to procure landing gear components under the presolicitation notice titled "16--LANDING GEAR, RETRAC." The specific requirement involves the acquisition of 5 units of National Stock Number (NSN) 7R-1620-014183166-V2, which must be sourced from designated suppliers as per source control or selected item drawings, due to the unavailability of suitable technical data or government data rights for alternative sourcing. These components are critical for aircraft operations, emphasizing the importance of reliability and compliance with military specifications. Interested vendors should contact Gregory T. Koch at (215) 737-4377 or via email at GREGORY.KOCH@DLA.MIL for further details regarding this opportunity.
