Eaton Selected by Dassault Aviation to Supply Hydraulic and Fuel Systems for Falcon 10X
Why It MattersAwarding hydraulic and fuel architectures together with certification test infrastructure shows airframers pushing system integration and compliance evidence onto tier-one suppliers during development of a new flagship platform.
What happened
Dassault Aviation has selected Eaton to provide hydraulic power and fuel system technologies for the Falcon 10X, an ultra-long-range business jet that is still in development. The selection was announced in a press release from Eaton.
Eaton's Hydraulic Power Generation System will support critical aircraft functions: flight controls, landing gear, braking and steering systems.
The agreement also covers system-level modeling, validation activities and a test rig, all intended to support European Union Aviation Safety Agency (EASA) certification activities. Eaton also took part in ground testing related to the Falcon 10X.
Industry impact & what to watch
Hydraulic power sits underneath nearly every primary and secondary flight function on a business jet, so choosing a single supplier for generation, fuel handling and the supporting test evidence concentrates a large share of the aircraft's safety-critical architecture in one relationship. For an aircraft still under development, that kind of award typically signals that system design has matured enough to lock in major suppliers.
The inclusion of modeling, validation and a dedicated test rig matters as much as the hardware. Certification on a clean-sheet ultra-long-range platform depends on demonstrating system behaviour through analysis and rig testing before and alongside flight tests, and tying the supplier to that evidence trail gives the airframer a shared stake in the EASA process.
The next verifiable markers are the EASA certification activities the agreement is meant to support, since those are where the rig and modeling work will be put to use.
