As they're such old TCTOs, I don't have that info.

Year and tail number, type of autopilot. please. What parts have been changed? What has been checked?

The 130H-4-15-1 shows support equipment IPB. Support equipment is listed in the 130H-2-2.

I would ensure the 28V is getting to the power supply on pin B, as well as the ground on pin A, which is aircraft bonded. Also, the ground for the transmitter and indicators are tied to one aircraft ground. Since all four are affected, I would insurepower is good to everything before I started with anything else.

While I appreciate the kind input of my helpfulness, it has been a while. Definitely do what n1dp said, check the altitude inputs. Antenna lines have cause very weird problems. They can be checked using a RFLTS. If the problem seems at exactly 10k feet, it really would be an altitude malfuntion. I need to look at some old books to see if there is a missing signal on one of the inputs that would cause this.

Merry Christmas. I stole the pic too! Tiny

Late 90's or early 2000's. I know it came out when I was in Alaska, 98-01. There wasn't a TCTO issued for it that I know of, it was just used as an alternate antenna. It was mounted in the same holes that the old antenna used. It got rid of the corrosion problem caused by the copper band on the old antenna mounting surfaces.

Really glad you solved this one. I found out the aircraft was at Youngstown from my buddy, Joel. I think he may be your SCNS rep. I really do wish I had more experience on the newer birds. I retired in 2011 before the J models arrived at Moody. Keep up the good work. I miss sinking my teeth into a good problem now and then. Tiny

Yes, the synchrophaser was installed by TCTO 1C-130-936 or 1095 when the props were modified. Don't know what they had before that.

I am still looking at the books. Can't see power causing this since everything works unless the ALT Hold is set to ON. A few more questions... When this started 4-5 months ago, was any peculiar work done on the aircraft right before it started happening? Were all boxes swapped between two aircraft or from supply? Was the Acceleration sensor changed out? Doesn't that feed both systems?

Yes, that antenna is no longer available. The aircraft was modified using two blade antennae. The information is in 1C-130H-4-34-1, section 4 Fig 9. It may be easier to get some from a retired aircaft in AMARG. If you need more info, let me know.

You would have to get that from WR-ALC at Robins AFB, GA.

I am going to ask some stupid questions because I only worked E's, 74 H's, early gunships and MC-130E's. Does the altitide signal for the ALT Hold come from a Air Data Computer? Are there two? I reallyneed to know where the ALT info comes form going to the Flight Director. The info in the GS-34 is marginal, and I couldn't find anything in the old H-2-13. All of my material is at least 22 years old as well. After looking for info, I remembered how lousy the books really were. What base are you at with this Herk? Tiny

Let me get this right, so I might be of help. The command bars on the ADI start floating around only if the A/P Alt Hold is engaged? Otherwise, they work as they should? Can I get the tail number? Tiny

Actually, the ring segement would probqbly be right under the panel, though I don't know why they would mark it there.

The front of the nacelle went to FS 399.05 on A models and 389.05 on E models, so 10 inches shorter.

Someone was screwing around, This goes on the ring segment at FS 165. Funny they taped over it when they painted at depot. "It ain't my job to remove it." It's been a while since I've been on an airplan, but I swear I've seen them before on the overhead panel. Tiny

On the overhead panel? About where? Picture?

Maybe check the Lockheed News issues for better pics.

Always goes to show you how accurate the books are.

Good luck, I found nothing in the books. If it were an accurate model, it wouldn't have them since the system was removed many moons ago. You may have the best pic of them. That tail # isn't even on the list of the seven aircraft that was supposed to have it, according to the GS-25-1.

Are you talking about the tank itself, or the support pylon. The pylon is in 130H-4-51-1, section 52-20-1, Fig 1 If you mean the tail cone on the tank itself, that would be in TO series 6J14 series. I don't have access to those.

130H-4-28-1, 28-10-00, Fig 6 612 2400-75-21.12 00624 . . . STRAP 612.1 2402-75-400SH 00624 . . . STRAP 613 373691-4 98897 . . . PAD, LOWER 614 373691-3 98897 . . . PAD, UPPER

I don't know, unless it's a training situation and the trainer is making sure the loader is in sync with everything going on.

What part?
