DLA Aviation is conducting market research via a sources sought notice to determine whether companies other than the current manufacturer, Arrowhead Products Corp, can manufacture or legitimately obtain a bleed air duct assembly (NSN 1560-00421077, P/N 12987-101A). This is not a solicitation or request for offers, and the government is not obligated to award a contract; responses are voluntary and no funds are available to pay for response preparation. The item is source controlled, so DLA cannot approve sources for it. Companies interested in qualifying their product for future acquisitions must contact the Design Control Activity specified on the source control drawing.
