Reminder to Secure Your Carabiner to Your Riser!

Brian Scharp - 2017/04/19 19:27:30 UTC

Has there ever been a hang glider flying related injury attributed to a carabiner minor axis failure?

I dunno. But I can tell you with absolute certainty that:

- With the adoption of Hewett Skyting Theory based towing in the early Eighties hang gliders totally ceased crashing due to rope breaks, premature releases, easily reachable releases, and crap drivers and started crashing because they:
-- traded safety for convenience by towing with stronglinks
-- didn't react properly to:
--- Infallible Weak Link induced increases in the safety of the towing operations
--- drivers making good decisions in the interest of their safety
-- tried to fix bad things because they didn't want to start over
-- failed to realize the seriousness of their situations until it was too late
-- made no effort to release
-- just froze

- Subsequent to the 2013/02/02 Zack Marzec invisible dust devil induced towing fatality at Quest:
-- the Tad-O-Link became permanently extinct as a factor worthy of any mention in any analysis of any lockout crash
-- premature releases and rope and weak link breaks started becoming dangerous again

How often do you replace your carabiner?

Many pilots then started using two, but that made hooking in and unhooking a pain, and potentially hazardous in strong winds.

Extending the hang strap with rock climbing slings

Pedro Enrique - 2015/09/26 19:01:18 UTC

Take a look at the picture attached. Now, imagine the yellow strap is my hang strap (both emergency and main together) that connects to the glider. I picked up a couple of slings from the rock climbing store, 27kn, and attached them like so to my hang strap.

Do you know what material the paraglider biners are made from? Most hang gliding biners are now made of steel. Since the change from aluminum, I only replaced mine to upgrade to a spring locking gate. When aluminum was used a pilot had to mindful of something called the endurance limit. Metals weaken as they are load cycled. The higher loads, the lower the cylces. The endurance limit is the amount of strength that material will level off having after a very great number of load cycles. Aluminum essentially has no endurance limit. That means, if used enough, eventually it will fail. Although that may not happen in your lifetime, there have been some cases of aluminum biners snapping with very little load. Steel has an endurance limit somewhere around 40% of it's ultimate strength. My steel biner is rated for about 9000 lbs. If it weakens to 3600 lbs, it will still have sufficient strength to never be in the failure path. Further the ultimate strength of the biner is likely a good deal higher than the rated load. Still, I will likely change it when the zinc coating is depleted and it starts to rust, or if I notice resistance or grit in any of the moving parts. If it developed a burr, I would likely just sand it out.

$15 pacifiers

Jim Rooney - 2005/09/20 13:11:43 UTC

Sorry, I don't see the logic in trying to save a couple bucks on equipment that I am litterally entrusting my life to. "Pacifier"? may be... but there's an old saying out there... "You never need the backup, until you need the backup".

I know of at least one pilot out there that flies with two caribiners. His logic makes more sense to me... you can't have too many backups.

So how often do you assholes replace your keels?

Somebody explain to me how it's possible to stress a steel carabiner connected via a strap of nylon webbing (which would be Dacron or Spectra if this sport had a fuckin' clue what it was doing) to an aluminum tubing keel which is supported by an aircraft with sailcloth surfaces stretched on an aluminum (or carbon) airframe all of which is supported by air at just about all relevant times.

Never mind. Please continue finding solutions to totally nonexistent problems while doing nothing or worse about any of the blindingly obvious moronic crap that kills participants on regular bases.

More evidence of the astounding difficulty the sport of hang gliding has in understanding the concept of a weak link.

Not convinced there's much to be gained there, but I'm not seeing a down side no matter how minute the advantage.

If we were really after a lot more no cost safety and comfort we would all fly suprone.

I expect to see more (including wheel landings) if the average pilot age (and possibly wisdom) continues to increase.

[Tad Eareckson]

There's NOT much to be gained there - but people:
- spend thousands of extra dollars gliders for not much gain
- win and lose world championships over issues of not much gain
- occasionally die for want of a couple feet attempting to make landing fields

And, yeah, there's no downside. And there's the additional upside in that nylon sucks with respect to UV tolerance.

And I started that thread closing on nine years ago and nobody else has gone with any low stretch alternative 'cause...

Guess we need a new poll for how often you replace your crimp tool.

Another new one for the list.

A question !! should i replace my carbine after 15 years?

A question !! , I am flying same carbiner now for 15 years , should i replace it ?

Two different misspellings in the space of five and a half minutes - both original.

Yeah sohrab, replace your carbiner/carbine every 15 years or 15 hundred flying hours, whichever comes first, and make sure you never do a hook-in check (gives you a false sense of security) or preflight sidewire stomp test (grinds your wires into sharp rocks and work hardens them). You'll fit right in.

List amended accordingly.

I replace mine whenever they break.

- A harmless suspension system inconvenience which spares you from the danger of getting even higher and falling even farther. (And fuck those muppets making more of this crappy argument that being in the air is somehow safer than being on the ground.)

- And then you also repack your parachute (assuming your hardware store quick link backup holds) - win/win.

Mike Bomstad - 2017/04/24 15:09:34 UTC

What's the possible harm from doing so vs the possible harm in not?

It boosts the stupidity level in an already terminally stupid sport.

P.S. Coming from a total fuckin' asshole who can't even figure out a system for making sure his fuckin' carabiner is connected to his fuckin' glider just prior to his fuckin' launch.

Tad just likes to go from forum to forum starting shit.
He was been banned from the hangliding.org, and this same shit has been hashed out on the OZ report.

...multiple sources. Over three and two thirds years since that Aussie Methodist dickhead killed himself for the purpose of the exercise and not a single syllable on the issue since.

But DO stay in there helping your fellow douchebags find more stupid solutions to nonexistent problems.
