I have no idea without a callout in the IPB.

There are way too many LAC processes to remember that much. Also, some wiring was replaced by newer designs. The 1-!A-14 has the story on aircraft wiring.

You will have to contact Lockheed. I used to have access to those LAC processes when I was working.

Not a pneumatics guy, but it looks like an expansion joint like the type used in plumbing. Doesn't the parts index indentify it?

Try swapping the TCAS processor with another aircraft. It is always goo to know you have a working unit, same with the antenna, swap with a good aircraft.

I would think anyenna or one of the cables. Are you sure all cables are connected properly?

Munir, since it makes no difference which phase is monitored, any phase could be used. I have no idea why they chose phase C. Maybe the relay was closer to a phase C connection. The only person that probably knows is the engineer who designed it back in the 1950's.

Sometimes, I think you think too much about these details. 😅

Sorry, I have no idea.

Again, I have never heard of a DCU. What system is it?

I have never heard of anything called that, Munir.

There are 9 of them. all #3 in the pic. Location: OW sta 185 and 293, and Ail Sta 103.5 on the wings, FUS STA 671, 701, 731.

Munir,

For valve #40P107? Cage code is 82829

Don't know why the #1 system pressure would affect #2. The worst thing the USAF did was put two 99.9% error free systems on the same bird. Woud have been so much better without the second system. The RF interlock system is ridiculously designed. I don't see that causing your problem. Wish I could be of more help.

Make sure the antenna cables are connected correctly. There is a possibility that two are swapped.

Not familiar with that RADAR. Given all you have changed, try changing the waveguide between the R/T and the antenna.Corrosion may cause false targets.

I couldn't find an old TCTO that made the system inoperational. This note was in the old 130B-2-4. There is also no mention of C-130B or E having it in TO 1C-130H-2-70GS-00-1.

Looks like AMETEK may be a source. There is a POC on page 2. The reference is on page 25.

I can't even find that part number in the C-130 T.O.s

I don't know how you would make this, it is extruded.

Glad it worked out for you. Your statement is why it isn't done at field level.

Doing house stuff, building up the 302 for my Ranchero.

Same to you!

Good job!
