This opportunity is for the supply of a specific part that requires government source approval, meaning only pre-approved sources are eligible for award. Offerors who are not approved sources must submit detailed technical data with their proposal for source approval evaluation, but award cannot be delayed for this process. The part is flight critical, and the government has determined that technical data is insufficient to support full and open competition. A 365-day warranty is required, with defect notification due within 45 days of discovery. No budget amount, submission timeline, or performance location is specified.
