About this opportunity
The Defense Logistics Agency Aviation has awarded a firm fixed-price indefinite quantity contract for Aircraft Duct Assembly (NSN 1660-01-183-2008) on a limited-sources basis under contract SPE4A726D0399 on July 27, 2026.
The justification, issued under 10 U.S.C. 3204(a)(1), restricts competition to two known sources capable of furnishing the required supplies: Arrowhead Products (CAGE 70628) and Senior Operations (CAGE 98769). The statutory basis is that the item must be acquired from manufacturing sources specified on a source control drawing (AMSC B) and has been designated a high reliability item where probability of failure would be unacceptable. A sources sought notice and Request for Information posted on January 27, 2026 yielded no contractor responses. Market survey confirmed that historical prices were fair and reasonable, and price fairness was established using intrinsic value engineering analysis and price analysis based on similar items. One additional source, S3 AERODEFENSE LLC (CAGE 4GPC1), was identified during market research; actions to overcome competitive barriers included posting a pre-solicitation synopsis with Procurement Note L2.2 restricting alternate offers for this source-controlled item. The contracting officer approved the justification on April 1, 2026. The contract term is three years with no options. NAICS 336411 (Aircraft Manufacturing); PSC 1660 (Aircraft Air Conditioning, Heating, and Pressurizing Equipment).
