  1. From what I understand, there are two different power units that can be used on the herc. The power units of one type have pins E & F shorted, the other does not. So, it could cause a problem with the power unit that doesn't have the pins shorted inside the unit. I found one thing in a book and I cannot remember which one, but all it stated was what I just wrote. 

    I do not have any books for the ground power units.

  2. You guys never cease to amaze me with your aircraft history. Since I worked on every airframe on the ramp, I was never tied closely to any single tail number. They all seemed to break at the same rate for us, which was all the time.

    It seems similar to growing up in one town all your life and knowing everyone, compared to being a military brat and moving constantly, always breaking and making friendships at the drop of a hat. I was the latter.

  3. Another subject that is not in any book that I know of. I believe the only thing that would prevent the gear from collapsing during the landing would be the friction washer, so the gear are secured by chains to prevent collapse. That is my best guess, but I am an avionics guy. Maybe one of the Flight Engineers can explain it better. Have you asked your flight engineers?

  4. I wish I could explain it any better. The MLG struts wouldn't have much movement front to back, so there wouldn't be much travel in a bellows, as you stated. Again, there is no better instruction in any books that I have seen. We avionics folks call it FM, Frikkin' Magic.

  5. From what I understand, the main purpose of the torque strut is to maintain wheel alignment. It will move back and forth just a little to absorb loads on the two landing gear struts. There is no need for pressure inside the unit. 

    Unfortunately, there is very little info in the tech orders.

    Not sure if paper documents are used much anymore. Here’s an Airman changing an antenna. The work instructions are on an I Pad (rotate speed-handle counterclockwise to loosen… etc). Electronic documents would make revision control a snap, but may not add to document security.

    Looks like he's removing what looks like the SKE OMNI antenna mount to me, but maybe it comes as an assembly so it is more expensive.

  7. Don't know anything about blue paddle lights. Here is the purpose statement from the TCTO. This TCTO wasn't even issued until 2001.

    "The purpose of this Time Compliance Technical Order (TCTO) is to document the installation of
    Night Vision Goggle (NVG) compatible cockpit lighting by replacing selected lens covers and
    caution/warning lights with replacements already in use by other C-130 airplanes. This action will
    provide optimal visual acuity for crewmembers using NVG and permits use of NVGs by aircrews
    throughout entire mission profiles without measurable degradation and within the airplane’s full
    performance envelope."
