HDI Spain is currently developing the main parts of the main landing gear’s hydraulic actuation system for Messier-Bugatti-Dowty (Safran Group). These operate at a pressure of 5000 psi.  This includes the Retraction Actuators (2 unit/aircraft), the Locking Panel (4 units/aircraft) and the Longitudinal Axis Positioners (2 units/aircraft). HDI Spain also does the (conceptual and detail) design for this equipment, in addition to certifying, industrialising and making it.
