  1. I will take 5 copies, sent you a message and email.
  2. No. The bulbs/lenses are not stock listed or authorized to be repaired. What variant of J-model do you work on? I wrote procedures to R2 most flight deck control panel bulbs for the AHMC-130J 31JG manuals. But the HUD panel was not part of that for reasons above.
  3. Seems WAY too complicated. Just drop the pallet from the ramp or onto barrels.
  4. You need to reproduce this leak on the ground. If you are transfering gas from every tank on the ground and not getting a leak, you might have a crack on the trailing edge of your wing! Max out your tanks on the ground and transfer fuel until you find a leak. You can jump up and down on wings to try and replicate wing bending. recommend you dont fly that plane until you find it Also recommend contacting Robins AFB engineers to assist you!
  5. It is also on the aileron control panel if you are working on short J's. Stretch J's (-30) do not have aileron diverter valves.
  6. Contact the engineer on the last page of TCTO. I forget his name but he can tell you what it is and if it matters.
  7. Normal brake accumulator has a restrictor because of anti-skid system. Emergency does not have anti-skid Anti-skid plus normal demand of brake application can deplete the accumulator rapidly. The restrictor ensures the utility system pressure goes to the brakes instead of filling the accumulator. The restrictor is free flow OUT of accumulator but restricted flow IN to accumulator. Acts like a priority valve for normal brakes.
  8. That is a manual override button, similar to override on flap selector valve/landing gear selector valve/ etc...only used that maybe twice that I can remember. Good for troubleshooting a valve that wont close when energized electrically but serves no purpose in the system operation
  9. Ahmer is correct. The "relief" for brakes comes from the power brake control valves. The selector valves do leak internally quite a bit once you get into the 4K+ range but thats not really the purpose of them. Really depends on what year/model/brake system your aircraft has because there are quite a few differences between the systems (IE: anti-skid valves, 3k or 2030 psi metering valves, parking brake valves, single/multi disk/carbon brakes, etc) There are also 4 different selector valve part numbers depending on which aircraft it is. Simple answer, no the selector valves dont have a relief valve
  10. Im confused your question Are you asking about anti-skid valves or brake selector valves? What makes you think there is a specific pressure for selector valves?
  11. Pretty much just used to help troubleshoot. Crew would never lay in the door and hold that button until they land unless there was something serious going on. Pressing the manual override forces valve to act as if it was energized. Pressing manual override valve is same as flaps extended past 15% (+/-5%). High boost state is energized, low boost state is de-energized. Pressing button is high boost states
  12. 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.
