NAVSUP Weapon Systems Support Philadelphia intends to award a sole-source contract to Sikorsky Aircraft Corp for two aircraft struts (NSN 1RD 1650 016629529 H5, Part Number 06205-03001-041) under an existing BOA. Delivery is FOB origin, and the government does not possess sufficient data to contract with other sources. This acquisition is subject to Free Trade Agreements and the World Trade Organization Government Procurement Agreement. Offerors must be government-approved sources; new sources must submit the required source approval data, and approval time normally prevents delaying award for new sources. No budget amount, performance location, or submission timeline is specified in the notice.
