  1. MC-130P, MC-130H, AC-130 or EC-130H?

    I'm going to assume the refuel valve you are saying you checked is the uarssi fuel valve which would be opening if all other tanks are receiving fuel.  Have you simulated a tanker? (Refuel through the uarrsi) to see if you can actually put fuel in the tank

  2. Also, we always seem to jump the gun to hydro issues but go into the ramp rigging procedures (job guide) and follow the steps that are checking for locking pressure.  Search for "800 psi" and you will find it.  Do those couple steps and you might just have a rigging issue.  Ramp should lock (in a perfectly rigged ramp) at 500-800 PSI.  I went back and read your original post and saw that you said 1000 PSI which is within limits of ramp operation but when having issues its always good to check your rigging.  Also I'm assuming you meant in position number 5?

  3. What base you at?  I might know some of the guys there

    I'm gonna add something that you can do to check this.  Just have a knowledgable hydro guy do this......

    Close the ramp and handpump at position # 5.  Have someone feeling/listening to the actuator.  Continue to build pressure to see if you can feel/hear a bypass.   Can do the same thing to manifold, hand pump to a good psi and feel/listen to manifold.  You might be able to hear it bypassing (if it is)

    You can check the other side by lowering the ramp to ads with arms connected and pumping at position #2, build good pressure and feel/listen for bypass.

    What model are you on? H1/2/3,J?

  4. Check the ramp lock restrictor (it is forward of the ramp lock actuator) (looks like a red check valve).  If this is clogged or damaged, it will block return pressure of actuator enough to prevent it from locking.  Take it off the hydro lines and inspect it.  If this is determined to be good, check the locking pressure of the ramp actuator by installing a pressure gauge and using aux pump as source.   If pressure is lower than it should be, manifold needs to be looked at.  This is not a cure all here but at least it will get you started, hard to troubleshoot over text (don't get the full experience of the issue)

  5. Lockheed service news is a great source for technical things relating to a/b/e/h c-130

    Google: lockheed service news archive

    Also get ahold of the lockheed training center at little rock or a local field training detachment.  They have massive amounts of training material

  6. I think this aircraft was at Hurlburt for a while and used as an inflight refueling trainer for new Spectre crews prior to doing an actual inflight refueling with an AC130H. It was also used for pilot pro work at Hurlburt if I remember correctly.

    thanks!  That makes sense

  7. Give me some details. (What hydraulic source? In-flight or on the ground? What is pressure dropping to? Have you checked the MLG snubber above the forward strut?)

    Are you sure the high speed side of the gearbox is engaged?  

    Make sure the flow regulators are installed free flow towards the motor (regulated flow away from motor) (up line regulates down side of gear/down line regulates up side of gear)
