As the legacy hydraulic test stands such as MJ-2A, MK-3A, TTU-228-1A&B, AM27T-2A (A/M27T-2A), Electric AM27T-12 (A/M27T-12 with NSN: 4920-01-502-2587), Diesel AM27T-13 (A/M27T-13 with NSN: 4920-01-273-8848) and 88043-100 (NSN: 4920-01-279-4762) in the US inventory with old technology are aging over 30 years, United States Air Force (USAF) has contracted Hydraulics International, Inc. to design and develop the new generation of Hydraulic Test stands with the latest state of the art features and components.
These Universal Hydraulic Test Stands (UHTS) have been qualified to the most rigorous military requirement testings such as environmental, Electro Magnetic Interference, Mobility, reliability, maintainability, etc.
Some of the new features are TIER III multi-fuel engine, fully military qualified hydraulic purification system, system diagnostic, built-in test system and Human Machine Interface touch screen operator panel.
F-16 including T-50, FA-50, KF-21, F-4, F-5, F-18, C-130, C-17,C-5, MiG29, Su-30, A400M, F-2A, F-2B, F-CK-1, Rafael, Gripen, Hawk, Eurofighter, Transport Aircraft & Helicopter etc
HII ‘s new generation of Universal Hydraulic Test Stand (UHTS) with the latest state-of-the-art features and components. UHTS utilizes a high resolution LCD Display HMI (Human Machine Interface) with resistive touch screen for operation and monitoring of UHTS System and functions. HII is currently on Contract with USAF to build UHTS. Accepted in-service by USAF for supporting their F-16 and can be used to support any transport or fighter aircraft or helicopter in their inventory.

Fluid contamination can be devastating to an aircraft, causing flight problems, safety issues, damage to expensive components and unscheduled aircraft downtime.
USAF Hydraulic Purification Articles:
UHTS comes with an integral built Hydraulic Purification System (HPS) that provides continuous cooling, filtering moisture and to remove hydraulic fluid particulates, water, chlorinated solvents, absorbed air & gases removal from hydraulic fluid. Keeping hydraulic fluid clean and eliminates the need of changing hydraulic fluid for a long period of time. HPS work in a very cost-effective way to minimize hydraulic fluid usage, minimize hazardous waste disposal needs, reduce deployment foot print and sharply reduce hydraulic maintenance and associated costs.
Purification Performance
1) Contaminant removal: 55 gallon of hydraulic fluid in 5 hours.
2) Water: From 1000 to less than 200 PPM.
3) Chlorinated solvents: From 400 to less than 100 PPM.
4) Air & Gas: 100% dissolved air removal, 98% (by volume) removal.
5) Particulate: Cleanliness level equal to or better than NAS 1638 class 3.
These UHTS are for replacing old or aging MK-3A or MJ-2A or other old OEM Models, which are also being operated by air force worldwide for supporting their F-16.
Hydraulic Purification System (HPS) is integral built in UHTS to provide following:
