Bobby, You could probably fix that with a patch, The actual name of the part is a pressure box, p/n 408323-01. A replacement would have to come from a retired aircraft in AMARG. They are a real bitch to get out, as i helped on one. The problem comes when you remove that tub, a complete DVS alignment would have to be redone. I cannot get to drawings anymore to check the specs of the box, but I believe it is some type of resin construction. Maybe Mike Bishoff, if he's on one of these days, can tell you. If the crack is small, I would suggest stopdrilling it, then a small patch placed on top, but, I'm not an engineer.

I wish I could, but I don't have any connections at WRALC, as I am retired, and I never worked on J-models. I would contact the manufacturer of the LRU. You can try Lockheed, but I doubt they'll want to let you know. Have you switched it to partial to see if the display changes? I would have.

Not sure what you are referring to, on what model aircraft, or where this is selected. The is only one RADAR frequency. Can you be a bit more specific?

Is this doppler the APN-218 system? Repairs to he radome skin are very limited. This if from the shop manual. 6-10.1 Radome Repair. Major radome damage requires antenna boresight correction constants be verified once repair has been accomplished. Antenna boresighting is a depot repair function. Scratches, etc. to the radome not exceeding 0.004 inches in depth and 3 inches in length need not be repaired. Intermediate level maintenance is limited to repair of minor abrasions and scratches in accordance with paragraph 6-10.2 and removal of oil and similar contaminants in accordance with paragraph 6-5. l.b. Minor radome abrasions and I scratches are defined as follows: a. Damaging agent has not deformed the radome surface. b. Damaged area is free of all fragments of any type metal. c. Abrasions or scratches do not exceeds a depth of 0.010 inches and an area of 0.06 square inches for the APN-230 or do not exceed the dimensions shown in figure 6-1. NOTE Limit repair to only the damaged area of the radome and only a one time repair of that specific area. 6-10.2 Repair of Minor Pits. Abrasions and Scratches. Make minor radome surface repairs as follows: a. Clean radome in accordance with paragraph 6-5. b. Wipe area to be repaired with a clean lint-free cloth dampened with Axerel 2200 or equivalent. I c. While area is still wet, rub briskly with a dry, clean lint-free cloth, turning cloth frequently. d. Wipe with a clean, lint-free cloth liberally dampened with P-D-680, Type III or equivalent. I e. Rub dry with a dry, clean, lint-free cloth, turning cloth frequently. f. Lightly abrade area with a fiberglass brush or 320 to 400 grit sandpaper and dust abraded area with a clean, dry bristle brush. g. Fill nicks, scratches or abrasions as required using polyester resin with 1/2 to 1% MEK peroxide as the curing agent. h. Using 320 to 400 grit sandpaper, sand the cured polyester resin to restore the original contour. Repeat step d to remove sanding residues, and allow the surface to air dry for at least 30 minutes before applying primer. i. Apply primer coat (SCDPE0028-1); limiting thickness to existing primer coat and cure at room temperature for one and one-half hours minimum. I j. Apply finish or urethane coating (MIL-C-83286) Color No. 26081 or 36081 (APN-218) or Color Number 16081, 16118 or 36081 (APN-230), limiting thickness to existing outer coat and cure at room temperature a minimum of 24 hours

The ETCAS, GCAS/GPWS & Digital Autopilot are fed by the Analog altitude signal. The indicators get the Aux Analog and Digital Altitude signals. If there are no GCAS or ETCAS problems, I would check the Aux and Digital lines to ground. Maybe one of the lines is shorting to the shield. These wires are also spliced. Whether it will cause an R/T fail indication on the indicator, I have no idea.

It would be easy enough to put an ammeter across the battery and see if there is any current flowing. Easiest way would be to pull the ground off and hook the ammeter up there.

Hope this is good enough

Sorry, it's 53-199-00. I can't figure out how I did that except for old age...

Fitting part # 371603-1 C-130A-3 1. General. Depot Level Repairs are those repairs that may require a higher degree of skill and/or specialized equipment or facilities which are not normally available at the organizational level of maintenance. Prior to performing any of these repairs at the organizational level, authorization and possible assistance is required from WR-ALC Engineering. Refer to Table 1 for a listing of Structural Repair Kits. 1C-130A-3, 59-199-00, page 6, D.1. Replacement of Part No. 371603-1L and -1R Floor Bulkhead End Fitting at Fuselage Station 597 and Installation of Vertical Beam Splice Part No. 7843161 at Fuselage Station 597. Applicable to 73 models and prior. Part No. 7843161-01 for left side. Part No. 7843161-02 for right side.

Sorry, I am not familiar with the FMS system at all. Have you tried to do multiple alignments to reduce the error? Can you swap out INUs, #1 with #2, or with another aircraft?

Those are the only instructions that I know of. I believe the -3 procedures were taken from the old B-2-12, which cannot be used. The ISO guys at Moody have removed many of them IAW the -3. What problems are you having?

Dude, it is in Fig 171 of the (H)H-4. Get with Tim when he gets back from the PIWG. He doesn't have anything else to do.

I have an interactive training thing I can send you, if I can get it to work on a DVD. Interested? Private message me your snail mail address. If I get it work, I'll send it.

2105, damn, you're optimistic.

Just tryng to help a kid out who just joined the USAF and will be an aerial refueler. He has a lot of questions I can't answer.

I know this is off topic, But does anyone know of a KC-135/KC-10 tanker forum?

Why not swap the ADSs? The newer ADS units use ARINC429 data. There could be something wrong with it. I have no wiring data for you birds. You don't have any NATEC guys that can help you?

Webflis shows as a special feature of this part, TO 5L6-3-31-4, which is an IPB for it. The maintenance book is either a -2 or -3. I have no access to look up books anymore, so I don't know what depot controls that pub.

That part number is the complete installation kit for TCTO 1731, SYNCHROPHASER REWIRE AND PROPELLER BALANCE / PROPULSION MONITORING SYSTEM INSTALLATION ON C-130 AIRCRAFT 1560K0188668ALG 3341520-1 Top Kit – Synchrophaser Wiring 1560K0188668BLG 3341520-3 Top Kit – Synchrophaser Wiring Dash number was dependant on which model was modified.

Does the J have the Ctrl Alt Del keys?

I've never heard of a MATT receiver or AFTRS-R. Sorry.

How's this?

The Missile power plug is different. It has 115VAC 3 phase, and is a 4 pin connector. The iron lung connectors have the wierd two arched contacts, and I think they used the iron lungs for medivacs out of Nam.

C-130 convention?

Larry, the VOR antenna was relaced by a new design using two rectangular antenna mounted on a panel. The panels were never manufactured, but were local manufacture. An unbelievably stupid way to handle it. When they came out, they just called it "an alternate method". So, the ARN127 or 147 mods did not include the antenna change. The major problem with the original antennas, besides removing and reinstalling, was that they had a copper strap on the outer edge that butted up against the aluminum skin. For some reason, aluminum, copper and moisture just don't play well together. In some aircraft pictures, you can see black under the bottom of the antenna on the left side of the tail. The antenna had to be removed during a #4 iso to check and repair the corrosion. Whether they pulled these out at AMARG because of this, or as supply requests, I don't know.
