Recently I have noticed that the hydraulic pump
seems to cycle more than usual when the flaps are going into the down
position. Going down it cycles once every second for about 6
seconds. Going up it cycles one time.
I am trying to check the accumulator pressure but
it looks like I am going to have to take the accumulator out of the plane to do
this since the end cap which protects the schrader valve won't easily
turn. Before I started the disassembly process I thought I would get some
opinions and advice on if there is a problem and what to do about
it.
Also, with the hydraulic pump breaker pulled, the
pressure in the accumulator will cycle the flaps to the opposite position but
not much more. My thinking is that the accumulator is not totally bad but
just has low pressure.
If I remove the accumulator for maintenance, what
air bleeding will I have to do?
Any advice and help would be
appreciated.
