Sole Source Justification for 4D InSpec Machine Service Contract

This document is a Sole Source Justification memo from the Department of the Air Force, Oklahoma City Air Logistics Complex (AFMC) Tinker Air Force Base, dated April 20, 2026, justifying the award of a five-year service contract to 4D Technology Corporation for maintenance and calibration services on twenty-two 4D InSpec Machines.

The 76 PMXG requires ongoing service for 4D InSpec Machines used across B3001 facilities for surface defect identification and measurement on aircraft components. The contract includes loaned equipment maintenance, troubleshooting, software upgrades, and ISO compliance support. The justification establishes that 4D Technology is the sole source reasonably available because: (1) only the original equipment manufacturer possesses the proprietary equipment and calibration access necessary to maintain precision accuracy following repairs; (2) entrusting service to non-OEM providers would introduce unacceptable risk and cannot increase competition at this time; (3) market research confirmed no other vendors are certified service partners or can provide comparable 4D InSpec Machine servicing under NAICS Code 811210 and Product Service Code J066; and (4) previous contract FA813221P0038 was awarded to 4D Technology Corporation. The vendor is a small business (CAGE code 3B1T0) located in Tucson, Arizona. The contracting officer determined in accordance with FAR 12.102(a) that the circumstances deem only a single source reasonably available for this acquisition.
