This is a sole source requirement for the repair of two Control Display Units (CDUs) for a critical application, intended for award under an existing Basic Ordering Agreement (BOA). The government lacks sufficient data to contract with any source other than the current one, and new sources require prior Government Source Approval, which cannot be delayed for this award. The initial induction period for repair is 365 calendar days from contract award, with a possible extension of an additional 365 days. The contractor must propose option pricing for up to 10 units over the entire contract period, with separate pricing for the second year if applicable. Performance location is not specified.
