Translation of "Circuit hydraulique de commande de vol " (French → English) :

Other key features include a fully marinized structure and engines for continuous corrosion resistant operations in a maritime environment; extensive use of composites to increase resistance to corrosion fatigue; state-of-the-art crash-worthiness features in the areas of structural design, load attenuation, passenger safety, payload retention, fire suppression, and emergency escape; triple redundant digital fly-by-wire flight controls and hydraulic systems; Rolls-Royce AE 1107C engines, which share the same engine core as found on the CC-130J; modern avionics with glass cockpit displays; a number of radar options to include weather ...[+++], maritime search, or terrain-following and terrain avoidance; an ice protection system, which includes both anti-ice and de-ice capabilities certified into known moderate icing—and most of our testing of that system was actually performed in Shearwater; and an open passenger and cargo cabin with roller rails, winch, hoist, and a rear loading ramp to provide the SAR techs with the clearance required to safely perform all necessary ground and airborne tasks. The V-22 program is in full production.

A break, impedance, or short-circuit to earth in the electrical circuit, defects in the hydraulic or pneumatic leads, Bowden cables, solenoids or other components controlling or transmitting the energy intended to activate the concealment device.

Fuel; flight control; hydraulic pneumatic systems

a. Hydraulic, mechanical, electro-optical, or electro-mechanical flight control systems (including fly-by-wire types);

3.15.2.2. a break, impedance, or short-circuit to earth in the electrical circuit, defects in the hydraulic or pneumatic leads, Bowden cables, solenoids or other components controlling or transmitting the energy intended to activate the concealment device.

The review found that some wiring systems were difficult to inspect and that there were insufficient inspection criteria for corrosion on flight control and hydraulic systems.
