This opportunity is for the repair of two dual control valves for Navy E-2C Aircraft, with the work intended for the country of Egypt. The contracting activity plans to solicit only Northrop Grumman Systems Corp. as a sole source due to the government's lack of repair data. All responsible sources may express interest and submit capability statements, but this is not a request for competitive proposals. Source approval is required for new sources; however, the government will not delay award while approval is pending. Interested parties must follow the Source Approval Information Brochure for Repair when submitting proposals.
