Hydraulics failure- helicopters
Failure of the collective pitch boost system on a Blackhawk can result in a very heavy collective. IIRC, it can push up with the equivalent force of 80lbs of weight. It was certainly enough to lift me out of my seat, even with the leg straps done as tight as I could bear them, it's really a two pilot job to fly it in that condition.
212Man,
Are you asking if each Hydraulic System can be turned off individually by a Control Switch?
I cannot imagine this day and time the Blackhawk would have the old S-58T/S-61 AUX/Primary Hydraulic set up as I cannot imagine the US Army not spec'ing a dual/equal system with the ability to shut off a malfunctioning system.

Memory serves me the 540 rotor system Charlie Model had accumulators too.....for the Collective system was it?
It was designed to allow for two full cycles of the Collective....meaning from full up to fully down twice.
As it was only fifty years ago I flew the B and C model Hueys......the recollection of those days is getting a bit dim.
