LONGERON

The Defense Logistics Agency awarded The Boeing Company a firm-fixed-price contract valued at $349,531.05 for the procurement of a single line item—LONGERON with National Stock Number 1560015142821 and part number 204-70045-215—under delivery order SPE4A119G0013, originating from solicitation SPE4A7-23-R-0099. The award, issued on July 24, 2026, was conducted as a sole source acquisition justified under FAR 6.302-1 due to the proprietary nature of technical data, restricted manufacturing capabilities, and the absence of alternative sources capable of meeting the stringent performance and reliability requirements. The part is classified under AMSC codes K, N, C, B, V, and Y, mandating compliance with MIL-STD-2175 for Class 1 castings, special inspection facilities, engineering source approval, source-controlled production, and high-reliability standards, with inspection and acceptance responsibilities implied to rest with the government under DLA Aviation Supply Chain oversight. Contract administration details are limited, with no specified payment office, accounting codes, invoicing method, or designated COR/COTR/PCO contacts, though funding is traceable through PR 0086704480 and NSN 1560015142821. Delivery and performance timelines are undefined, with no stated FOB terms or place of performance, and packaging, preservation, and marking requirements are not specified beyond the use of CAGE and NSN for system traceability. The contract includes potential options for increased quantity and term extension, though these are not formally defined, and no clause language from FAR or DFARS governing options, security, or organizational conflict of interest is present in the available documentation. The award process relied on a completed AVN Form S53, a technical certification by the Aviation Chief Engineer, and legal review by the Aviation Deputy Chief Counsel due to the acquisition value exceeding $15 million, with proposals submitted electronically via DIBBS and SAM.gov under a Firm-Fixed-Price Large Buy RFP structure.
