The Department of Defense, through the Defense Logistics Agency (DLA) Aviation at Philadelphia, PA, is seeking to procure 11 units of a flight-critical aircraft component identified by NSN 7R-1680-016878030-E7. Due to the lack of available technical data and the necessity for Government source approval prior to contract award, only previously approved sources will be solicited for this requirement. Interested parties must submit the necessary documentation for source approval along with their proposals, as offers lacking this information will not be considered. For further inquiries, potential bidders can contact Michael Kneble at (215) 737-5619 or via email at MICHAEL.KNEBLE@DLA.MIL, with a proposal submission deadline of 45 days from the notice publication date.
