The Department of the Navy plans to purchase a specialized test set for its F/A-18 E-F Program and VFC-204 stand-up. - Government buyer: Department of the Navy, Naval Air Systems Command (NAVAIR), Naval Air Warfare Center Aircraft Division (NAWCAD), Lakehurst. - Procurement: One Concentrator Test Set, Type TTU-518/E, part number 1779AS500-2, NSN 4920-01-429-8089. - OEM and vendor: Cobham Mission Systems is identified as the intended source and only known manufacturer. The notice also names Carleton Life Support Systems, Inc. (Cobham Mission Systems). - Sole-source rationale: Cobham owns the technical data, specifications, and drawings needed to manufacture the item, and the Government says it lacks sufficient data to compete the requirement among other sources. - Notable requirements and risks: Qualifying another source would require design reviews, first-article testing, evaluation, and logistics-support updates estimated at $125,000–$200,000. An alternate asset could also be incompatible with the Navy-approved configuration. - Contract type: Firm-fixed-price procurement. - Period of performance: Not provided.
Description
This effort is for the manufacture and delivery of quantity of one (1) Concentrator Test Set Type: TTU-518/E (PN: 1779AS500-2, NSN: 4920-01-429-8089). This item is for the F/A-18 E-F Program in support of VFC-204 stand up. It is the Government's intention to issue a sole-source, firm-fixed price procurement to Cobham, CAGE: 99251.
Under authority 10 U.S.C.2304(c)(1) and implemented in FAR 6.302-l(b)(l), to try to develop this “asset" would incur costs that are not expected to be recouped through competition. Any attempt to procure a different part number would require the Government to fund a Preliminary Design Review (PDR) Critical Design Review (CDR) First Article Test (FAT) and Test & Evaluation (T&E) effort for a new vendor. The Government would have to fund personnel to be on the Source Selection Team to review proposals. Any change in form, fit or function would require changes to the existing Integrated Logistics Support (ILS) (technical publications, spares inventory, calibration) which would incur additional costs, estimated to be $125,000 to $200,000 for update. The process required to obtain an alternate asset is cost-prohibitive and would force the FMS Partner to utilize an asset that is not supported, compatible or interchangeable with the USN-approved configuration.
This requirement will be processed under the authority 10 U.S.C.2304(c)(1), only one responsible source and no other supplies or services will satisfy agency requirements. Market Research was performed by the Lakehurst Technical team. The only known manufacturer of this item is Carleton Life Support Systems, Inc. (Cobham Mission Systems), CAGE: 99251. Cobham owns all the rights to the technical data, specifications, and drawings required to manufacture this item. Additionally, the Concentrator Test Set has an Acquisition Method Code of 3H, stating the item should be acquired directly from the manufacturer as the Government does not have in its possession sufficient, accurate, or legible data to purchase this part from other than current source(s). As such, it is the Government's intention to issue a sole-source, firm-fixed price procurement to Cobham, CAGE: 99251.
