Scope of Work
The requirement is for Balance Spindle assemblies that must be dynamically balanced to tight tolerances to prevent torsional vibration in F-22 and B-2 PTO shafts. Specific items include:

Contract Details

- Place of Performance: Hill Air Force Base, UT

Sole Source Justification
This acquisition is justified as a sole source to Collins Aerospace because they hold proprietary designs, technical data, assembly drawings, and engineering methodologies for the required balance equipment. Collins Aerospace has no authorized distributors or resellers for these specific assemblies. This approach is necessary to avoid work stoppages, as existing balance equipment can only be serviced by Collins Aerospace. Future market research will be conducted to identify additional sources.
