VSE / Velocity Infinity risers - SERVICE BULLETIN VSESB001 Can't Post

Just a heads up, first I've seen of this and didn't see any mention of it on the forums



http://velocityrigs.com/...letin%20VSESB001.pdf

DATE:June 1, 2013 SERVICE BULLETINVSESB001, REV 0 # PAGES: 4
SUBJECT: MAINRISER, LOCKINGLOOP WEAR
STATUS: MANDATORY INSPECTION
INDENTIFICATION:
1. Allmain risersmanufactured by Velocity Sports Equipment(VSE)
BACKGROUND:
Severalmain risers have been found in the field with frayed/partially cutlocking loops(the white type
2A loop). The amount and location of damage on the loops varies, leading VSE to conclude theremay
be several contributing factors.
A loop failure can resultin an out ofsequencemain release and reserve deployment which can cause an
entanglement. Due to this danger, VSE feels allmain risersshould be inspected according to the
following Service Bulletin.
WHOCANINSPECT:
Any FAA certified senior ormaster parachute rigger orforeign equivalent.
INSPECTIONPROCEDURE:
1. Remove the cutaway handle / yellow cutaway cablesfromthe rig and disconnectthe risers.
2. Closely check the locking loopsfor damage.
a. See “WHAT TOLOOK FOR:NORMAL WEARORDAMAGE” to determining ifthe locking
loop shows normal wear orsigns of damage. If in doubt, please contact VSE.
b. If damage isfound,the rigmust be repaired before it can be jumped. See
“RESOLUTION”
c. If normal wearisfound,the rig can be jumped, but VSE suggests periodic checksmoving
forward. See “RESOLUTION” formore details
3. Reassemble the system, being careful notto reverse the risers orintroduce a twist.
WHATTOLOOKFOR:NORMALWEAROR DAMAGE?
Please review the following picturesto see the difference between loops with normal wear and
damaged loops

Is this the same issue that was posted in this thread?

Appears to be.

I just double checked mine, and it appears fine, but I don't have a lot of jumps on these risers.

They don't mention a cause, other than to say that the location of the wear can vary, and that there may be various contributing factors.

So one infers that there might be some roughness on grommets on risers and cutaway cable housing ends, and thus on some grommet dies?

Grommet problems are much more rare these days than 20+ years ago, before stainless was common and when standards were lower.

There's a few contributing factors, which is why it has taken as long as it has to issue a service bulletin, and why we're essentially dealing with the cutomers on a case by case basis.

We don't feel that this is a grommet tooling issue, since the sharp edges that we've seen on the cutaway housing grommets have been formed over the course of many jumps, in at least 3 different locations on the grommets. BUT the wear issue is not only caused by sharp edges on the cutaway housing grommets, so please inspect your risers and get in touch with VSE if you have any concernsSmile

Sounds like an evolving issue that we'll eventually hear more about, something where the specifics haven't been on skydivers' radar before.

What differs for VSE risers compared to most others is the AMP fitting that integrates the grommet in the riser to the hard housings in the risers. Obviously that gets looked at too, whether it could have any unexpected influence.

Greetings-- Wow, I just jumped onto the gear forums,and got the update on the vse risers, Those look very scary and am glad you gave us a heads up. To top it off I just received my new infinity last week, just waitin on my canopies to get here to hook it up. What I,m really trying to say is that I,ve encountered that problem before with my other infinity, but nothin to that extreme, I'll definitely keep my eye on this. Certainly don't want to have to worry about this while I'm turning onto final. Sometimes there's PEACE.
