The Department of Defense, specifically the Naval Air Warfare Center Aircraft Division, is seeking to establish a 5-Year Basic Ordering Agreement for the maintenance, repair, and calibration of Turret System Test Consoles (TSTCs) used in support of the Marine Corps AH-1Z aircraft. The procurement is intended to be a Sole Source, Fixed Price contract with Texas Management Associates, Inc. (TMA), the sole developer and manufacturer of the TSTC, as they possess the unique technical expertise and data necessary for these services. This opportunity is critical for ensuring the operational readiness and reliability of the TSTCs, which are essential for the performance of the AH-1Z aircraft. Interested parties may contact Tammy Fossa at tamara.d.fossa.civ@us.navy.mil for further information; however, this notice is not a request for competitive proposals, and the Government will not pay for any responses received.
