This document is a Brand Name Justification for the acquisition of a specific tool setup for crimping generator lugs on PN 35-8255-801 used with TF33-P103 left-hand assemblies. The justification is based on the need for a tool compatible with existing depot-level crimping dies to ensure reliable electrical and mechanical connections, as governed by Technical Orders (T.O.) 1B-52H-2-23 and 1-1A-14.

• Sole Source Justification: The document asserts that only a specific brand's tool setup can ensure exact die-to-tool alignment and compliance with technical orders without extensive and costly requalification or redesign.
• Compatibility Requirement: The tool must be compatible with the depot's existing crimping dies and integrated into depot-level maintenance processes.
• Market Research: Limited market research was conducted, identifying only one responding small business out of four contacted, and one additional potential vendor. This led to the determination that proceeding with a small business set-aside is in the Government's best interest.
• Contact Information: For further information or clarification, bidders can contact Mark Todd at OC-ALC/OBCA, (405) 739-8311.
