This is a sole source requirement for the repair of two rotary wing blades, as the government lacks the necessary data to contract with any source other than the current one. The work is intended to be awarded under an already established Basic Ordering Agreement (BOA) with NAVSUP WSS Philadelphia. This acquisition involves items subject to Free Trade Agreements and the World Trade Organization Government Procurement Agreement. Offers from non-approved sources must include a complete source approval submission with their proposal to be considered. For questions, contact the provided email address.
