The Government is seeking potential sources capable of repairing the F-15 Air Data Processor (NSN 6610-01-432-8459FX, P/N: 2118952-5), which requires engineering source approval from the design control activity. The part is a military-unique item that must be manufactured to a specific Honeywell drawing specification, and the Government does not own the necessary technical data or test equipment for organic repair. The contractor must furnish all material, support equipment, tools, and calibrated test equipment. The known source for this requirement is Honeywell International in Phoenix, AZ. This is a Request for Information for market research only and does not constitute a formal solicitation or guarantee future contract awards.
