    NESA WINDOW HINGE INOPERATIVE

    Is the window arcing?

    NESA WINDOW HINGE INOPERATIVE

    Typically NESA windows can be flown when in-op but it limits the pilots because they must avoid icing conditions. This would be a judgement call by YOUR aircrew members. Every Air Force or operator is different.

    Bat Birds Pull to Left

    What was the fix?

    Bat Birds Pull to Left

    1. What speed? 2. Does pilot have to use opposite steering wheel inputs to correct? 3. Has neutral/streamline of rudder control surface, trim tab and boostpack been checked? 4. Are the nose tires the same tread pattern and height? if you stick a level across the top of nlg tires, it should be level or match the level of your surface (ground). 5. Has back pressure been checked for brakes? should be no more than 70 psi in return pressure. Anything more can create a dragging brake. Easiest way to find a dragging brake is have crew taxi for about 10 minutes and check temperatures of brakes, they should be similar between left and right side. Brake bleed kit can check back pressure. 6. Have you checked rigging of steering cable/chain 7. Have you checked the NLG scissors and bolts for tightness? Slop in the scissor linkage can create a very uncontrollable NLG steering

    Hydraulic Fire SOV

    So there is a relief valve in the suction shutoff valve on the firewall. Is that what you are asking about or are you asking about the system relief valve? System relief valve opens at 3450, full open (flows more than engine pumps) at 3850 and reseats at 3150. Suction shutoff valve has a relief valve that opens to prevent a rupture in suction line. opens around 135 psi and reseats around 105. I would have to 100% double check those two numbers but thats what I remember.

    C-130/Hercules Steering Control Valve

    Are you asking what pressure is ported? There is no pressure reduction in steering control valve, pressure to the actuators depends on how far you turn the steering wheel. Full turn is 3k psi to the extend/retract side of applicable actuators (left/right)

    C-130/Hercules Steering Control Valve

    This service news talks about it. If in doubt and you dont know how to rig/overhaul the valve, Just replace it. V12N4.pdf

    Slime Light Reference?

    They are electroluminescent formation lights. All items labeled 9 in attached picture. Modified by TCTO or came with from factory on H-models. Typically only guard/reserve units paid for TCTO

    C-130/Hercules Steering Control Valve

    The valve is set to a neutral position during overhaul by centering the spool between the outlet ports. What that means is that the valve should not port fluid when in neutral position, this can be a hard position to achieve during overhaul. Neutral position should not port fluid. Neutral uses the internal spring loaded accumulator to take out shocks and movement of the wheels during takeoff and landing. Are you having problems with the valve porting left or right and not holding the wheels in center position?

    C-130/Hercules Steering Control Valve

    What do you mean be failure? I have changed steering control valves on all of the MDS/models you listed. Normally they are changed for leaking out of limits, changed during shimmy troubleshooting, or changed because of normal wear. I have never seen one explode or anything crazy.

    Allison 501-D22A Engine

    I would say no especially if you are going off of type certificate (FAA) data. Submit an engineering request to FMS and see what they say.
  12. hehe

    EDP

    Yes, as long as you have a run around installed for New York Air Brake pump (if installed). There are Lockheed Service News that talk about this.

    Icing Conditions

    DTIC is where all Air Force Research and test reports get databased. Ill do a search and see what I can find. Is there a certain model of FLIR that you are looking at?
  14. hehe

    Icing Conditions

    I don't know that it was ever designed to completely de-ice. I believe the heating is only there to prevent the image from being obstructed. There are plenty of models that have no de-ice or heaters built in and they work fine. I believe the original picture you posted is a model without heating. Do you have access to DTIC? I find a lot of good reports on that site and it might be a good place to look for this.

    Icing Conditions

    It looks like an N-model, def not a B-model for sure. Maybe he meant nice "P-model"?
