Speedbag retrofit to a non-Racer container

Recommended Posts

Not a rigger so I'm a little in the dark, is it the rubber bands instead of the elastic cord you normally see? Also, what is the possible effects of this?:)

My guess is that this was someone's redneck solution to a broken safety stow.



Or missing one;)

I have seen miss-routed lines,velcro protector still on the free bag,but never thought that somebody can be so stupid:|
The look of the packjob is awful as well:S

Right. The "elastic cord" is called a "safety stow". It isn't attached to the bag. In theory, if one of the stows hangs up, the loose safety stow will just slide out. It's intended to reduce the chances of a reserve bag-lock.

It's also a TSO'd part of the reserve.

So what you have here is a non-approved modification to a reserve freebag that potentially increases the chances of a reserve bag-lock.

What you have here is really stupid, and illegal IMHO.:o:S

It's not a Speed Bag mod.

Just another example of poor rigging.

Even though it probably would have worked it's not a riggers luxury to deviate from the manufactures instructions.

Shouldn't the riggers name and certificate number be on the Packing and Data card?
Assuming there was a card?

There never were rubber bands on early free bags, O-rings yes, not rubber bands.

After a few moments reflection, the Jump Shack did allow the riggers option of using rubber bands on it's early free bags, or still does?

Take a look inside a pre-Speed Bag Racer free bag and you will see two white rubber band stows close to the "o" grommets, this was to loop the rubber bands and then they were routed through the "o" grommets to the outside of the free bag.

I don't have access to my manuals now so maybe another rigger could chime in?

Most manufactures started with MIL SPEC rubber bands holding their freebags closed.

Para-Flite tried black rubber O-rings in the early 1980s, but eventually every one converted to Safety-Stows. Safety-Stows make the most sense at the low speed (eg. right after cutting away froma partially inflated main canopy).

Even Racer used Safety-Stows for a decade or so ... but then John Sherman invented the Speed Bag, with every (MIL SPEC) rubber band serving as a locking stow.
Speed Bags make the most sense at the high speed edge of the envelope.

But for a field rigger to randomly modify a freebag - without understanding the bigger picture - is just dumb!

Rob,
Thanks for jogging the old synapses.

I remember converting a few early RWS free bags with 4 locking/closing stows and standard velcroed pouch for the remainder of the lines.

Not all who reads these threads are riggers.. I know what a safety stow looks like, but some might not.. There is nothing wrong in knowing what you are looking at when you open a container. And know what it should look like, and not...

The Safety stow is part of the TSO. I guess a master rigger could go through all the hassle of filing the work as a major repair but in my opinion I can't believe its worth it at that point for one off builds. Further some manuals spell it out that only their factory stows are allowed to be used (Sunpath, Rigging Innovations). Getting the correct measurements for verification purposes from some of the manufacturers is easy, others not so much so.


Quote from the 2005 Parachute Rigger Handbook, by Sandy Reid:

=====
Many riggers fabricate these
loops in the field, which, in most cases, is an unauthorized
procedure. The Safety-Stow® loop is an integral part
of the approved reserve deployment system and is manufactured
under an approved quality control system from
approved materials. The rigger should use only OEM
approved parts for this.
