This is a sole source repair requirement for a gearbox input module, quantity one, with delivery FOB origin. The government lacks sufficient data to contract with other than the current source. The item is subject to Free Trade Agreements and the WTO Government Procurement Agreement. Offerors must be government-approved sources; new source approval typically cannot be accommodated within the award timeline. Unapproved sources must submit required data per the NAVSUP WSS Source Approval Brochure, and questions can be directed to Casey Brown.
