Collapsible Truth (Article #18)

Internet discussions get t
Believe it or not, there are ways to not take random, major deflations, but you have to be down with really understanding what causes them…the sad reality, is that many, many pilots do not get the proper instruction or continuing education and will experience problem deflations for all the wrong reasons…most all are preventable and many times the results are tragic.
Things that go bump in the day that should make you worry:
So now, you know my opinion that talking about what to do in a catastrophic deflation on an internet forum is the wrong conversation. Talking about why they happen, how to avoid them and finally how to prepare for said deflations is where all of the really good educators in our sport go. All this BEFORE you encounter scenarios that would deliver you major pain and/or expense.
Big Point #2
The only way to thrive and possibly save yourself from injury or death in paragliding is to get into the mind set of attaining “mastery” of your wing and then truly understanding your exposure. This begins with great instruction and a real commitment to persistent and consistent practice on the techniques that improve your mastery. There is no training available that will get you to where you need to be in two or three days. You cannot learn it from watching a video. Accurately understanding and managing risk requires a progressive, phased approach to learning that takes a real commitment, a lot of time and an experienced, great instructor.
Mediocrity plagues our sport. This is a mystery to me. I would understand if you were flipping a coin for a lunch spot, but not aviation.
Accurately and actively understanding and managing risk should be at the top of your list. Mediocrity won’t get you there.
Don’t try out the instruction you read on the internet for things like “how to get out of an 80% collapse at 30 feet from the ground.” Talk about these big ticket items with your qualified instructor. If you don’t get that he/she really understands this stuff well enough then find someone who does. Come see me (not a sales pitch…really) or anyone you can find that does over the water safety training. In addition, also seek out seminars that deal with flying in unstable air, advanced ground handling, etc.
Summary
Keep learning, question everything you read/hear…remember, wing mastery and accurately managing risk and exposure are your goals.

Time to check your gear
For good reason, we generally do not depend on a lot of things in paragliding as being "fail-safe." However, for most, one of those perceived "fail-safe" items is our sturdy carabiners. They come in all shapes, sizes and colors - usually in two varieties of metal: steel or aluminum.
The photograph above was submitted to me by my good friend, Gerry Wingenbach who noticed this AFTER he had landed on the South Side of the Point of the Mountain. This could have been catastrophic as the carabiner could have failed at too low an altitude to get out a reserve.
It would seem that most every harness manufacturer (free flight and paramotor) chooses to use aluminum for their stock harness carabiners. And why not, they are less expensive and much lighter than their steel counterparts. However, I believe that steel is a better choice and that every pilot should have the facts to make his or her own decision.
In 1992, my then business partner, Tom Lyde, and I decided to move our climbing gear manufacturing company from Austin, TX to Salt Lake City, UT. Peter Metcalf (CEO of Black Diamond) offered us a very generous package for manufacturing space in their 3900 south facility. We continued to manufacture their climbing harnesses and sewn runners for a number of years. As a result, I worked with some of the great minds in manufacturing at BD and learned a lot about the aluminum carabiner.
Aluminum carabiners are strong for their weight and I generally trust them for climbing until I drop one. Aluminum has a nasty habit of forming micro fractures that, if formed in the wrong place, can significantly weaken the breaking strength. This is not to say that EVERY TIME you drop an aluminum carabiner that this happens, but it is possible in aluminum and NOT in steel. There are other factors as well, such as improperly side loading the carabiner or loading without the gate locked or fully closed.
For paragliding, I generally do not use aluminum carabiners unless I know the history of the biner and can verify through visual inspection that there are no possibilities of abuse that could result in weakening its strength. This is because I, and others that frequently handle my equipment, sometimes drop my harness unintentionally on hard surfaces and I always here that unmistakeable metallic "ting" sound of the carabiner as it hits.
In hang gliding, I have always used steel carabiners...we even call it out as a recommended specification for tandem operations in hang gliding and paragiding.
For paragliding and paramotoring, I have always used and sold the Austria Alpine steel locking carabiner.
So, take a good look at your carabiners. If they are aluminum, make a good visual inspection of the rounded corners - these are the potential trouble spots. If you see any nicks or dents, I would replace them immediately.
