Multi Functional Test Equipment
MFGSE®, multifunctional ground support equipment
The MFGSE® is a state-of-the-art ground support equipment cart specifically designed for use with the F-35. Its unique modular design delivers a compact yet powerful solution capable of supporting a full range of maintenance activities—from routine daily operations to complex D-level maintenance. Thanks to its smart modular architecture, the MFGSE® can be powered either via the electrical grid or through a diesel-powered stand-alone unit, offering unmatched flexibility in diverse operational environments. All modules are engineered to meet the stringent technical specifications of the F-35 and include:
- Electrical Power Supply
- Preconditioned Cooled Air Hydraulic
- Pressure Supply Diesel-Powered
- Ground Power Unit (GPU)
The MFAGE®-LTM
The MFAGE®-LTM is the most compact model in the MFAGE series—lightweight, flexible, and designed for maximum mobility and versatility. This modular unit can be mounted on various trailers or trucks, or operated as a stand-alone system in the field. It's ideal for remote operations, such as aerial support, forest fire response, or offshore platforms like oil rigs where helicopter support is essential. Despite its compact size, the MFAGE®-LTM delivers full ground support capability with the following integrated functions::
- Electrical Power:
o 115V – 400 Hz
o 28V DC
o 230V – 50 Hz - Hydraulic Systems:
o Dual independent systems
o Hydraulic fluid de-aeration and super-cleaning for system integrity and safe operation - Pneumatics & Pressurized Air:
o For air starts and pneumatic tool operation
The MFAGE®-S series
The MFAGE®-S series is a single-axle ground support unit designed for exceptional mobility and air transportability. It can be towed on surface roads at speeds up to 80 km/h, navigates off-road terrain, and is fully compatible with airlift operations, including transport inside modern cargo aircraft or slung under a helicopter. This versatile GSE unit offers a comprehensive range of support functions, including:
- Electrical Power:
o 115V – 400 Hz
o 28V DC
o 230V – 50 Hz - Hydraulics:
o Dual hydraulic systems
o With fluid de-aeration and super-cleaning capabilities - Nitrogen Supply: Via onboard nitrogen bottles or integrated nitrogen generation
- Pressurized Air: For system support and air starts
- Pneumatic Power: Both dry and lubricated air for hand tools
- Lighting Mast: Telescopic mast up to 4 meters, providing reliable field illumination
The MFAGE®-T series
The MFAGE®-T series is a twin axle version primarily for use on the platform or ships:
- 3 types of Electrical power: 115 Volt – 400 Hz, 28 Volt DC and 230 Volt – 50 Hz
- Hydraulics: two systems, including hydraulic fluid de-aeration and super cleaning.
- Nitrogen bottles or nitrogen generation
- Pressurized air
- Pneumatic power, dry and lubricated (for hand tools)
- Lighting mast, 4 meters high.

Standard with Improved Closed Loop system
Contrary to a conventional closed loop system, with the Improved Closed Loop or Integrated testing/cleaning system, the hydraulic oil is continuously cooled, filtered, degassed and dehumidified. This system is a standard feature of all hydraulic equipment of Sun Test Systems.
The result is regenerated clean and de-aerated hydraulic fluid in the aircraft after hydraulic testing. Also maintenance time on the hydraulic system of the aircraft is reduced (less leakages, less replacement of hydraulic fluid, less waste) and operational reliability will increase and handling of the aircraft is improved.
