This is a qualification requirement for manufacturing a specific electron tube (P/N 588R901H02) used in F-16 A/B AN/APG-66 transmitters. The process requires a potential source to certify facilities, verify technical data, manufacture a qualification article, and complete testing and evaluation at their own expense. The estimated cost for this qualification effort is $3,000, and the estimated time to complete it is 180 days. Sources may apply for a waiver of these requirements if they meet specific criteria, such as having previously supplied the item or a similar one. Successful qualification results in being listed as an approved source but does not guarantee a contract award.
