Utility hyd system venting fluid

Recommended Posts

The utility hydraulic system keeps venting fluid into the drip tray during flight. It doesn’t appear to be bleeding through from the Aux system. I am a bit stumped any ideas ?

  I take it the reservoir is filling up and over flowing then dripping out?

What model?  Without knowing this, this is all I can give you for now.

I'm assuming, from your post, that the reservoir level is fine on the ground with the engines running.

If that is true, I would change the system filters for Utility (case drain, pressure and vent).

If this changes nothing, check accumulators.  Are you having to service accumulator pre-charges often for normal brakes or utility system accumulators?  

If nothing changes from there, I would need to know what model.  Depending on the year, you could have things like case drain relief valves, runaround circuits, suction boost runarounds, etc.  Let me know what model and I can help you out.

      H model emergency brake pressure 3800psi, normal brakes 3600psi during finals on approach. Cannot replicate fault on the ground. All other hydraulic pressures remain within limits.

      Hi everyone, I've been trying to figure out why the elevator boost system is reversed, compared to the aileron/rudder assemblies. I've heard theories, and have looked into the NATOPS, and the lockheed manuals, sorry airforce I dont know your books too well, but I'm looking for a pub or something official saying why.
      I have heard that the elevator boost assembly was simply designed to be installed upside down, which I guess makes sense. But I have also heard that it was put in that way to prevent confusion since if you're inspecting it, you'd have to face aft and therefore get the filters (for example) confused. I find this hard to believe, but any help would be greatly appreciated
