This is a sole source requirement for the repair of one specific servo control unit, intended for award under an already established Basic Ordering Agreement (BOA). The government lacks the necessary data to contract with any source other than the current one, and any offeror not already an approved source must submit a full source approval package with their proposal. The induction period for initial units is 365 calendar days from award, with a government option to extend it by an additional 365 days. The contractor must propose pricing for a maximum of 10 units over the entire contract period, with separate pricing required for the second year if prices will change. The total contract value for threshold purposes will be calculated using the highest proposed unit price multiplied by the maximum of 10 units.
