Overview
A Ram-Air Turbine test is one of the mandatory ground checks that keeps an aircraft’s emergency-power system airworthy. RH Aero supplies the complete, Airbus-certified RAT Testing family—engineered and produced by TEST-FUCHS and distributed worldwide through RH Aero. The core kit comprises the PGRAT1 test unit with integrated flow-/pressure instrumentation, matching RATMK ground-check motors for each airframe, and the optional RAT Safety Interface Kit (RSIK1) that protects the drive-shaft seal during the run-up. Versions are available for the A320/A330/A340, A350 (RATMK350) and A380 (RATMK380) programmes.
Use Cases
Supported aircraft & part numbers
- A319/A320/A321, A330-200/300, A340-200/300/500/600 – PGRAT1 test cart + RATMK motor (Version 1 or 2)
- A350-900/-1000 – RATMK350 motor kit with 5.000 psi rating
- A380-800 – RATMK380 motor kit (5.000 psi, 33 gpm)
Typical operations
- Scheduled ATA 29 functional checks during heavy- or calendar-limit maintenance
- Post-maintenance verification after hydraulic-system or RAT repairs
- Line-maintenance spot checks using battery, mains or aircraft 28 V DC supply (PGRAT1 cart is self-powered)
Benefits
Airbus-certified hardware: Ensures full compliance with OEM maintenance procedures.
Integrated instrumentation: Digital flow, digital pressure, and tachometer let technicians record results without extra gauges.
Skydrol-resistant stainless-steel cart: Long service life and safe operation in hydraulic environments
RAT Safety Interface Kit: Flange assembly prevents seal damage and collects any leakage during the run
Modular, aircraft-specific motors: Correct torque, flow and speed for each RAT model; quick-connect hoses with 5 000 psi couplings
Works with our Hydraulic GPUs: Meets the 40 gpm at 3 000 psi (or 5 000 psi) flow requirement specified for the motors
Why RH Aero
By pairing TEST-FUCHS engineering with RH Aero’s global logistics, spares and training network, we deliver a single-source, certified solution for every Airbus RAT ground test—from narrow-bodies through the A380. The result is faster set-up, precise data capture and reliable protection of critical hydraulic components—so your emergency-power system is ready when it’s needed most.
