  1. If you do a search of the original build of the C-130, you'll find pictures of the original fuselage being submerged in a large pool and it was pressurized using that fitting to check for leaks and the pressure of final damage. The fitting was never taken out of the engineering drawings, so it is still there today.
  2. With the old dual rail systems, the last section at the paratroop door was held down by those rings.
  3. If it appears fuel quantity increases with air speed with an aux tank, then there would be air flow pushing on the bladders of the aux tank. When the bladder is compressed in this way, the fuel level seems to climb. In a way, it does, since the actual level of the fuel rises. There is a panel inside the wing box that gives access to the inboard most bladder. We have had this panel not installed once and the bladder crushed the fuel probe. I don't know if anyone is checking this post from over a year ago, but I haven't been here in a while.
  4. Well, someone at one time seemed to think that loss of air-conditioning in the flight deck was a grounding item. If the flight deck flow control valve doesn't open normally, it can be pulled open. If it can't be shutoff normally, it can be shutoff manually. However, mid 70's, someone thought that it was not necessary and they took that part of the system out. I have never seen it intentionally used, but it has been unintentionally shut off many times. Interestingly, the temp control boxes will still drive the temperature system to cool with the master switch off if the system keeps running and there is an overheat in the ducting. I can only guess that the designers thought that someone would manually turn the system on?
  5. I think we might be missing part of the procedure here. In our checklist, the test is the Fuel Governor and Pitchlock Check. As far as the pitchlock goes, it doesn't matter if the TD system is in auto, null, or locked. Of course, auto and locked will permit overtemp protection. However, the fuel governor check requires that we can compare a specific fuel flow to a specific RPM. Apparently, those who provide us the chart for adjusting the fuel control governor to get the proper fuel flow do not want the TD system altering the fuel flow. It appears they want "uncorrected" fuel flow for whatever RPM the fuel control limits the speed to. It is easy to do, painless, and that is what our procedures require. Why not?
  6. Yes, we still have to check to see how much torque is required to tighten the propeller retaining nut prior to removing the prop. If it is too low, we are to damage the propeller shaft so that it cannot be reused. Of course, that would mean that we would have to change the gearbox if not the engine itself.
  7. Sounds like Ramrod has done a few ramp and door rigs. I have also found the blocks mounted under the forward end of the cargo door to be the incorrect dimension. We had four of them found to be 1/4" too tall, and they contacted the ramp early - lifting the door when they should not have. I don't have my notes with me now, but LMCO can tell you the top angles of the lock saddles in order to ensure that you do not mix the saddles up. Once they get crossed, you will find the #2 locks tight and pull your hair out trying to get it correct. Bushings are a big issue, and they are easily missed because they are invisible to us unless we remove the ramp. However, the easiest way to see if anyone installed them vertically instead of horizontally is to check for side-to-side movement of the ramp and the actuator end. Lockheed Service News gives a method of checking for the proper amount of play. If the play is not there, the bushings are installed incorrectly.
  8. I've also had one because of the twist in the connector at the prop itself. The "power in" wire found a ground when the insides turned and the wires crossed.
  9. I am not referring to the one who does gay comic books! I am asking about the Herky Bird drawings. Does anyone know where I can find them online? Is there a book of his drawings that I can get my hands on?
  10. We do have one, but we have not experienced the problem you mention (that I know of). If we did, I'd be sure to readjust the governor, though.
  11. We had an overhaul facility rebuilding our fuel nozzles, but they were not doing ALL the tests after the rebuild, so they were sending them back to us without a certain leakage check. After having to replace the nozzles a couple times for the fuel smell in the AC, we asked about their testing methods. They had to revamp their checklist to correct the leakage that was getting through inspection. The smell is different from the one we get after a compressor wash. It isn't any more pleasant though.
  12. Fuel nozzle leakage. New Engines or those with newly overhauled fuel nozzles sometimes experience this. We found that our overhaul facility was not doing all the checks on the nozzles they were sending us, so we were getting back nozzles that would lead around the head and make the air-conditioning smell really bad.
  13. It would help if I could see your setup for checking the balance to see if everything is being done correctly. Also, ensure that your scale is in calibration and being place in the correct spot for weighing. If nothing has been done to the aileron and it is out of balance, it either has always been that way or some critter crawled in there and died in an unfortunate location. If you are doing everything correctly and it still will not come back to the limits, then you'd either have to get engineering approval to add more weight or you'd have to replace your aileron.
