Quick Summary

The Defense Logistics Agency (DLA) Aviation has issued a Justification for Other Than Full and Open Competition for the acquisition of eight DUCT ASSEMBLY, AIR C units (NSN/PN 1660-013551931 and 65312-12191-043). This action is being pursued on a sole-source basis with Sikorsky Aircraft Corporation due to their status as the only known source capable of providing the required supplies.

Scope of Work

The requirement is for eight units of the DUCT ASSEMBLY, AIR C, specifically identified by NSN 1660-01-355-1931 and part number 65312-12191-043. These assemblies are for the CH-53 Helicopter and fall under Product Service Code 1660 (Aircraft Air Conditioning, Heating, And Pressurizing Equipment).

Contract Details

Type: Firm Fixed Price contract, with potential options for increased quantity or term extension.
Estimated Value: To be determined.
Set-Aside: Not applicable, as this is a sole-source justification.
Place of Performance: Richmond, VA, United States.

Justification for Sole Source

The acquisition is justified under 10 U.S.C. 3204(a)(1), which permits acquisition from only one or a limited number of sources. Sikorsky Aircraft Corporation (CAGE 7826) is identified as the sole known source. The Original Equipment Manufacturer (OEM) is unwilling to sell data rights, making the development of a technical data package for full and open competition cost-prohibitive due to the extensive reverse engineering required.

Efforts to Ensure Competition

A Sources Sought notice was posted on beta.SAM on September 8, 2025, but no interest was received from other potential sources.
The acquisition will be synopsized on or about September 18, 2025, and any firm requesting a solicitation copy will receive one.
Future Actions: If other manufacturers express interest, a solicitation will be prepared. Interested sources are encouraged to submit source approval packages for DLA Aviation's consideration.

Submission & Evaluation

This document is a justification for sole source, not a solicitation. Specific submission and evaluation criteria will be detailed in a future solicitation if competition arises.
