5. Single Source Justification (SSJ) - PAMAS SBSS Liquid Particle Counter Redacted.pdf

This is a Single Source Justification (Simplified Acquisition) document for a federal procurement action by the Air Force Space Command, Propulsion Maintenance and Sustainment (AFSC/PZIMA). The procurement seeks to acquire a PAMAS Syringe Bottle Sampling System (SBSS) Liquid Particle Counter for the 802 MXSS/MXDTA unit located at Robins Air Force Base, Georgia (DoDAAC: FE2067). The estimated contract cost is redacted. Delivery is required 12 weeks after award with on-site installation, and familiarization training must be provided to four users upon installation completion.

The justification document establishes that single-source procurement from the PAMAS brand is the only reasonable option due to mission-critical requirements. The PAMAS SBSS Liquid Particle Counter is identified as the sole replacement tester compatible with the Beckman tester and the only equipment capable of measuring particulates in the 10-200 micrometer range and 200+ range to the specifications required for aircraft particulate testing. The Beckman equipment no longer supports the required calibration, and timely completion of particulate testing is essential before aircraft can return to home station, making delays unacceptable to mission capability. Market research was conducted across the Dynamic Small Business Search and SAM.Gov databases using NAICS Code 334516 (Analytical Laboratory Instrument Manufacturing), resulting in zero small business alternatives. The contracting officer, SSgt Bobby Ballow, determined on March 4, 2026, that circumstances justify Other Than Full and Open Competition (OTF&OC) authority under FAR 12.102(a).
