Couldn't tell you when or where, but it seems as though there was an accident where a stem had been repeatedly worn on a sharp edge and finally croaked.

I havn't seen a completely severed cable stem, but have seen many severly damaged but loading/catching falls over sharp edges. Damage was everything from a simple kink to near 70° bends with numerous breaks in the cable... hey, it happens. ALL gear has limitations! I'm not saying that is what happened here, but it does happen. (I've also seen bolts that 'appeared good' rip out, but that's another discussion)

Jay It makes sense that it could be. Just need to track down an actual incident, but the idea doesn't seem too far out; I've seen worn stems, isn't too hard to imagine them wearing more then getting whipped on over a harsh enough angle and being done. I can't imagine it being a one time deal on an undamaged stem, however. Previous wear would have to have already been established.

No it only indicates my utter astonishment that anything else could go wrong with Aliens. My astonishment that anyone could look at the cable on a Alien and think that a sharp rock edge could sever it. My astonishment that I could still be astonished at this whole sordid tale. It works better in person.

Until you personally take an alien, put it over a sharp edge, tie into it with 10' of cord, and drop 180 lbs until it fails, I don't think you have anything to offer me. So spare me the sideline speculation.

To everyone: Does anyone know the details on the fall?? I mean how far above the Alien was he when he fell? j_ung: Thank you for calling CCH and posting the info but I got a question...you mentioned that it seems CCH might not have been at fault (I hope so I'm looking at my aliens right now...they scare me). What makes you believe that? A Broken stem could be mfg problem as these cables are pretty thick. Dude, I'm not trying to be a dick, just wanted to know if I missed something you wrote. Thanks, -JR

j_ung wrote: I don't know why I'm bothering with this, since I don't own any Aliens and I don't intend to ever buy any under any circumstances, but I called CCH and asked what's up. Understand, I'm not acting as a journalist in this case, like I was during the original recall episode. I'm just curious to hear what's going on. CCH was indeed contacted by, I assume, pinsandbones, in regard to the failure of his Alien. Said contact included pictures of the failed unit, which, apparently showed a broken cable stem, not a failed braze. So this failure is not the same as the recall failures. That MIGHT actually be bad news, since it may -- MAY -- point to an entirely different problem. However, it's important to note that cable-stemmed cams are vulnerable to some extent to sharp edges, of which it appears Souder's Crack has plenty. Without any additional information, I'll allow this failure might be due to that. To me, it's beginning to appear that this is not the result of any shortcoming on CCH's part. Dave Waggoner also told me that he requested additional contact from the pinsandbones several days ago, but has not gotten it. Not sure where pinsandbones is, but he's not here either. Hey, pinandbones! Post up your pics, mate! Lastly, I suggested to Waggoner that he post up with an update on this. I told him that, even if he has no additional information, a lot of people would appreciate some kind of proof that they care about what people think. It kinda seemed like that hadn't occurred to him. Waggoner's exact words were, "Yeah, I should probably go ahead and do that today." Though the limited information available appears to vindicate CCH, at least in this particular incident, I'm not seeing a whole lot to make me change my mind about them and Aliens. Quality assurance aside, they still seem to be unaware of or indifferent to the legitimate fears of their customers. Instead of responding to worst-case scenarios, as I believe they should, they still seem to act (or not act as the case may be) based on what they hope is true. Aliens remain the only cam on the market today above which I refuse to climb. ______________________________________________-- Hmmmm, at odds somewhat with the op's post:

Now, about the alien. I will attempt to answer many of the questions posted. It was not a broken stem due to an edge or any other strange action on the cam. It was a vertical placement and broke at the head. Where it broke, was well into the crack. It was NOT A RECALLED ALIEN. I was seventy feet up or so when I fell from just a few feet above the piece. i will be posting pictures of the alien, but not yet. Just know that it did not fail because of an edge or any other contortion. It was a good clean placement. Thanks again for the concerns and I will post more when I have all of my facts together.

I read through Injuries and Accidents once in a while cause often there are good breakdowns of accidents, and I prefer to learn about potential problems and solutions without bleeding too much...and I always hope that since there's no way to undo an accident, at least we can use the information to prevent repeated pain! I'm reading this late (limited internet access) but hope there is still a chance for some useful breakdown and answers. So far there's been tons of replies, discussion of gri-gris, aliens, novice belays etc...but no clear details about anything. Early on, someone posted that they witnessed the scene--met the female belayer, quoted her, helped. They basically said the climber was cleaning the route after both had climbed. This would suggest the climber was being lowered while cleaning, meaning it is really unlikely the grigri was threaded backwards etc, and if a piece broke, it must've been a top anchoring piece (which creates an unlikely situation itself--I don't know any climber who would, after repeated climbs, lower off a single (and so sacrificed) alien to clean and move on. If it was a leader fall (I guess from the eyewitness it would have been his second climb on the route) how did he deck?? At 70 feet up, surely he'd placed more pro than just the top alien which broke??! Now we come to the question if the top placement (the alien) broke, so he fell a little further and harder than usual, how did the belayer fail to catch him with a grigri?? Maby I missed something, but I think it'd be helpful to know what happened, so those reading about the accident can perhaps save themselves from a similar fate! thanks, -p

Maby I missed something, but I think it'd be helpful to know what happened, so those reading about the accident can perhaps save themselves from a similar fate! thanks, -p There are two seperate accidents refered to this weekend. The accident named in the title refers to a climber who was leading Souder's Crack. He was leading up a questionable flake section, made it past w/ some sketch gear inserted. Once he reached the more stable part of the climb, he plugged a yellow alien (which should have been the "thank god" piece), climbed a small amount above it and fell. The cam ripped apart, and the lower protection in the bad flake pulled. This is the accident sparking the CCH discussion, as the cam was post recall, stamped tensile tested, and failed at the cable's insertion point into the head. The other incident involved a grigri, and a climber cleaning the route. Hope this helps clear it up.
