This is a combined pre-solicitation and solicitation for the repair of three aircraft refueling tanks for Foreign Military Sales to Brazil. The work is stated as sole source to the Original Equipment Manufacturer, Mission Systems Davenport, Inc., as they possess the essential repair data and capability. However, the government will consider capability statements, proposals, or quotations from all responsible sources, though only a source already government-approved for these repairs will be solicited. Potential alternate sources must provide detailed technical data for source approval, a process that typically takes too long to delay an award. Proposals will be considered if received within 45 days of the synopsis publication.
