NAVSUP WSS Philadelphia intends a sole-source procurement for eight units of an aircraft landing jack from Dutch Valley Supply Co., the original equipment manufacturer and only known approved source. The government lacks data or rights to purchase this part from other sources, and no drawings are available. Any unapproved firm must submit a Source Approval Request, but the procurement will not be delayed for approval. This is a FAR Part 15 non-commercial acquisition, with UID and Buy American clauses applicable, and it is not a small business set-aside. Interested parties may submit capability statements for consideration, but the government will proceed with the sole-source award.
