This is a sole-source procurement for a flight-critical item (quantity 1) that must be acquired from or repaired by a government-approved source, as no technical data or data rights are available for alternative sourcing. Only previously approved sources have been solicited, and new source approval typically takes too long to permit a delayed award. Interested parties that are not approved sources must submit the required source approval information with their proposal. The government intends to negotiate with only one source under FAR 6.302-1, but will consider responses for potential competition. Delivery is FOB origin, and the item must be sourced from the specified drawing or source-controlled part.
