This is a pre-solicitation notice for the sole-source repair of three pneumatic starters for Foreign Military Sales to Germany, with Honeywell designated as the only known approved source. While the government intends to negotiate with Honeywell, it will consider capability statements from other responsible sources. Any alternate source must be government-approved for these specific parts, and the approval process is lengthy, meaning a new source likely cannot be approved in time for this award. Interested contractors must submit specific company and technical capability information to the listed Point of Contact. Proposals received within 45 days of the synopsis publication will be considered.
