DLA Weapons Support seeks market research to determine if companies can manufacture or legitimately obtain NSN 1680-01-550-9425, Aircraft FMU Harness, currently made by Robertson Fuel Systems LLC under part number HM032-440-11. This Sources Sought Notice is for information only, is not an offer request or solicitation, and does not commit the Government to award a contract. No funds are available to pay for preparation of responses, which are strictly voluntary. The item is source controlled, so DLA cannot add new sources; only the manufacturing source on the source control drawing can approve new sources. Interested parties wanting to become an approved source may email Gladys Brown at gladys.brown@dla.mil, and the buyer will provide information for the cognizant design authority authorized to approve sources.
