Yeah the cutter can lock the reserve loop instead of cutting it. It happened in Poland a short while ago because of a mis designed cutter.

Are you sure it was because of the faulty design and applies on every cutter? Or it was just that particular specimen had some error in manufacture?

AFAIK: the Argus cutter has a circular blade as opposed to a wedge shaped one.

The Problem of the loop slipping to the side and not being cut completely is also an issue with wedge shaped cutters, thats why Airtecs cutter has the little plastic tube, to center the loop. The cutter has to have a little room to the sides, this creates a gap in which the loop could get stuck n. The gap is necessary, otherwise the cutter would get blocked when fired.

I don't know whether the Argus developers wanted to solve this by problem by designing a cutter with circular blade. Maybe someone else knows more about this....

Pressure sensor accuracy cannot be determined a self test. Indeed, the dynamic accuracy of _any_ component cannot be detected by a static test.

Well, "risking people's lives" is a bit overly dramatic. Put it this way - a product that has an expected life limit based on component aging is safer over its life cycle if it is retired at the end of that life limit. Making that mandatory will make it safer over the course of its life, since more people will discontinue its use at the end of its life.

>Using that logic, why not a 9 year life limit?

Because that may well be in the bottom part of the bathtub curve, and thus you'd be retiring at its most reliable point.

No loop lock, no faulty design. Oh and by the way no SB either.

So the pictures in the Polish PDF document (linked below) show the correct way Argus should cut the loop...?:

Please provide your version on what happened.

Are you serious? The SB was released on Sep. 5th and you want to tell us that you weren't aware of it on August 28th?

And also:

The Aviacom/Argus bulletin came out showing that the cutters had to be replaced before the next jump.

Within a few hours, a new version came out giving much longer (such as at next repack) to get the change made.

(That's not even visible in the original bulletin thread, as some posts were removed by moderators to clean up the thread.)

Although everyone makes mistakes, this was a major bulletin from the company, so one expects care to be taken.

It makes it look as if they are a little confused and uncertain of what to do with this whole messy cutter situation.

Just a wrong box tick in a template we fortunately don't have to use that often.

Ah, a template -- easier to do things, easier to screw things up...

(And to be fair, I've seen UPT mess up an SB & reissue it with minor changes but not even a name or version change.)

I have to apologize. The now released report of Aviacom regarding the incident in Evora on September the 4th, clearly shows why nobody at Aviacom could have been aware of a SB on August 28th. It would have been way easier to understand all that stuff if the facts would have been known by then.
