Decision was made to return and during descent we got a system-A engine driven pump low pressure light, with system-A quantity slowly decreasing. So the last part of the flight we only had the system-A electric pump and it seemed to do it’s job quite well, never noticed any flickering of the hydraulic pressure light.
ouch! That is a different scenario, namely contents loss rather than EDP failure.
And it sounds pretty concerning. Fluid loss from BOTH systems? How did that happen?
