Not true the packing certficate says canopy type, not canopy type and size. _________________________________________ Nullius in Verba

Wrong, they are rated at a minimum of 2500 lbs, maybe you are thinking of the 70101 chest strap adapter which is rated at 500 lbs and is stamped not forged. _________________________________________ Nullius in Verba

[Reply]Yes, Atom Tandem rigs - built by Parachutes de France use a 4-Ring system. P. de F. starts with a harness ring the same size as an RW-1. RW-2 and RW-3 rings are sewn to the bottom end of the riser, but the smallest ring is really a grommet set in a piece of tape. Are you meaning integrity risers? if you are I don't think you could discribe that as a 4 ring system as it the grommet through the tape serves the same function as the grommet on an "ordinary" set of risers. _________________________________________ Nullius in Verba

If you open your reserve, the RSL will stay conected to your main, however it will no longer have any conection to the reserve system, as the only point of contact is where it connects to the reserve ripcord, which isn't there anymore. (I'm not talking about a skyhook here) So even if your main subsequently comes out it should just fall away behind you. This is of course assuming you cutaway your main. the one exception to this system that I am aware of is the Jump Shack double sided RSL. With the Jump Shack system a main deployment after the reserve with the RSL still connected can cause problems. I see you jump at Weston, talk to Apples or Fordy this week end. _________________________________________ Nullius in Verba

In that case I agree with you. I just thought my eyesight was going John _________________________________________ Nullius in Verba

Ok Mick I'm lost! Do you mean the single Layer of Type 13? _________________________________________ Nullius in Verba

Sparky you've changed! You used to be so cuddley _________________________________________ Nullius in Verba

Also as far as I am aware PD Slinks are only approved with PR series reserves and IIRC not all of them. You can't use them on the 99 the 106 or the 281. _________________________________________ Nullius in Verba

Yes and only if they are in free fall and exposed to the air. _________________________________________ Nullius in Verba

Well if the lines haven't been off the risers seperating the 3 line groups, front, rear & control and running them down to the canopy is all it takes. This off course assumes they were on the links right to start with. In fact you can do it with just the control line as long as you eyeball the risers to make sure you havent let them twist through on themselves. Obviously if the lines have been off the links, each line should be checked for proper continuity from the canopy to the links and proper orientation on the risers. _________________________________________ Nullius in Verba

No I'm just posting the link. For the record I don't think A.A.D. are kidding you either. I just had a glance through the users manual and I couldn't see any operational parameters set out in regards to tempreture. I'm sure Airtec have those parameters in the cypres manual but I haven't looked. _________________________________________ Nullius in Verba

Statement in Regard to the Recent Vigil Activations and More _________________________________________ Nullius in Verba

Well I have a Loft and a Reserve packing area or 2 at my DZ and I can lock those up if I leave a packed main disconected, however if I left something in the main packing hall and I wasn't with it 100% of the time I would repack. I know I can connect a set of risers without putting the main on backwards. What I don't know is if anybody has moved them when I haven't had them in my sight. Anyway repacking isn't a bad idea, doing a line continuity check will make you that little bit more familiar with your gear and if nothing else it gives you a bit more packing practise and god knows some people need it. _________________________________________ Nullius in Verba

Clicky _________________________________________ Nullius in Verba

I was told 20% by my examiner, I wonder if there is a correct figure, maybe it depends on a lot ov varibles, machine speed, needle size, age of thread. _________________________________________ Nullius in Verba

Given that you are 54 lbs above pd recommended max for expert on your reserve, and .6 psf above the placarded max for your main, I'm wondering if this is just a troll? _________________________________________ Nullius in Verba

NOOOOOO don't be giving away the secrets of our dark art _________________________________________ Nullius in Verba

I hope not as the original poster says _________________________________________ Nullius in Verba

Have you contacted the manufacture of the rig? I think they might be intrested in this one, also check with them the spec legnths of your cutaway cables, you may have been supplied with the wrong pad. It's hard to imagine what might have caused this without seeing the rig, but it does sound IMO like some thing caused the cable to become misplaced during the jump. I would be very tempted to see about having some sort of mod on the the exposed cables maybe some type 4 square weave stitched to the MLW to form an extension to the hard housings that will cover the exposed Lolon cable, again have your rigger talk to the manufacture about this. I've seen it done on some rigs but I can't remember which one's of the top of my head. As an aside when I started jumping ram air equipment from rounds, I was taught to, take control, avoid if needed then do a 4 point check after deployment, the check was Handle, pad (pillow), cable, cable. _________________________________________ Nullius in Verba

You may well be right, as I said I was asuming the stitching was pulled above the harrness ring. I just cann't see the type of construction where the rear reserve risers are stitched to the diagonals above the confluence wrap passing any sort of testing though. Which is why I made that assumption. I'll join you in the queue _________________________________________ Nullius in Verba

I think that the stitching (or rather stitch holes) you are seeing above the harness ring have just been pulled out of place. You can see that the type 12 and type 8 which passes around and through the harness ring slot is out side the mudflap. I looked at that too, but I assumed that the torn stitching I could see was normaly inside the confluence wrap below the harness ring. That is the sitching we can see in the bottom left picture on the "intact" front reserve riser has been pulled above the harness ring either as a result of the 4 point pattern failing or later to make the images clearer. If your idea that the rear reserve risers have been stitched onto the front risers and the diagonal was correct, then that would be a stitch patern that is doomed to fail as you describe. I can't imagine that sort of pattern getting through any from of testing though so I assume it's just how the pictures have been taken. _________________________________________ Nullius in Verba

From the way the construction is discribed I would say it's "a normal" way to construct a harness. I have seen H/Cs where the rear reserve risers end in the confluence wrap, at the lateral back strap joint and some that have both risers go on to form the legstraps too. I personaly can't see this being a construction issue. _________________________________________ Nullius in Verba

That is an incredible amount of damage to be sustained from an opening. I have to wonder if the harness hasn't been subject to some thing unusual before this incident. I find these pictures quite shocking. Rob. It looks to me that both sides have had the rear reserve risers pulled out so I'm guessing the thread will be just as damaged on the LHS confluence wrap too. I agree it looks like 3" type 4 (Mil-W-4088) BTW we tend to use thread in metric sizes on this side of the atlantic, so I would say the thread would be M8 which is equal in strength to anything used by U.S. manufactures. Lexa. Do you know if the harness had had any work done on it? had it been involved in an accident that might have required a rebuild or had it been resized? _________________________________________ Nullius in Verba
