Bill Booth's opinion on spinning 3 rings: " Spinning the rings was never necessary. All you do when you spin the rings, is put salt from your hands on the hardware. By the way, each opening rotates the rings a little anyway. If you will look at cadmium plated middle rings with over 100 jumps on them, you will see a slight "compression" of the plating evenly all around the "back" side of the ring. Flexing the webbing was a good idea when we used 1 3/4" Type 12 webbing to attach the smallest ring on "large" 3-ring systems. (We've used 1" square weave for over 20 years now.) On mini-rings, flexing the webbing was never really necessary. We left it in the generic 3-ring instructions only because not all risers are made with the correct webbings, and it doesn't hurt anyway." Derek

If the risers were twisted together, then the cutaway cables were also twisted together. Without the protection of metal housings, this twisting causes the cutaway cables to be much harder to pull than normal. Also, if the cutaway cables are dirty, that can dramatically increase pull forces. Student rigs tend to be overlooked for regular, 30-day, 3-ring maint and cable cleaning. Derek

I think you are misunderstanding the issue. If the harness is rated to 3,000 pounds and a reserve produces more force than that, then the 2 are not compatable. This is the case for a Mirage and a PD-113R and others, I'm sure. If you want to lift 1000 pounds but your sling set is only rated to 500 pounds, you can't lift that load with those slings. Derek

Listen to other peoples reports on stuff, they can really save you a lot of head aches. Buy quality, even though it may cost a lot more, the product and customer service are usually worth it. Derek

Gotta have the biggest truck still? Derek

Sounds more like a line trim issue. Derek

Right, that is all I have said in this thread. Anything else just isn't there. Derek
-
Like I already said; "I'm not worried about the harness failing before the reserve or the harness or reserve failing at all for that matter, just the legalities." I don't think very many people know about it, you didn't. I am not complaining, just discussing it. Derek
-
No, it says that you cannot assemble a reserve that generates more force than the harness is rated to. That force information comes from certification tests. Where else would the force generated during deployment be measured? You couldn't know if the reserve generated more force than the harness was certified to unless you drop tested it. So to say the harnes has to be certified to more force than the reserve generates for drop tests is silly since you won't have that information until after you drop test it. If the reserve generates more force than the harness is certified to, you cannot assemble them. Um right, which means packing a PD-113R (and others) into a Mirage is against the FAA's interpretation of the FAR's. Derek

Thank You Perris Valley Tandem Master

I caught the same person twice on the same day one year at Lost Prarie. Derek -
I talked to Mirage on the phone several weeks ago. They said they would get back to me with an answer in a couple of days after they talked to the FAA. I called and left a message which wasn't returned. Without an answer from the factory, riggers be sure to check the avg peak force on TSO C23d reserves is less than 3,000 pounds before packing the reserve into a Mirage. Or at least be aware that the container is not rated for a reserve that produces more than 3,000 pounds average peak force during opening and packing one is a violation of the FAR's. Derek

Sounds like it was wrong from the start, and like it was already said, Vectran doesn't shrink. A Safire2 should open nice and soft, if isn't, something is wrong. Send it back and get it fixed. Derek
-
What type of lines does your main have? 20 jumps should not make a 1.25" difference. Something is wrong. Spectra shrinks from the heat generated by the slider sliding down the lines. Derek

A good demo is kinda boring to a skydiver [Edit: boring to a skydiving spectator, not to the demo jumper. Demos are tough, even the boring ones]. Ya, smoke would spice it up a bit or a flag, but they can also cause problems if the jumper isn't careful with them. Generally what would impress a skydiver scares spectators. Sounds like a well done demo to me. Derek

It was 60 days, changed to 120 days for synthetic fibers. It is still 60 days for natural fibers. Derek

Let it go. Competetion can be healthy, but if taken too far, it can be unhealthy. Derek

For new, ya. I got mine used in great condition for $200. It is a workhorse. Derek

A Singer 20U will do a nice zig-zag and has a knob you turn to lock it in place to make a very straight stitch. I really like my 20U. Derek

Which would not excuse repeated takeoffs or the stall warning horn going off above 100 ft +/-, except for turbulence. Derek
-
Your reply to; “2. One who doesn't climb the plane with the stall horn going off all the time (What is gained from that). Hearing the horn scream every time I rode up in the 206 with 4 other fatasses is something I look forward to never doing again...” Was; “Uh guys, would you like to go up in that 206 on a hot (humid) summer day with five in the back at anything close to a reasonable rate?” That is not the horn going of for a second as the aircraft lifts off and accelerates. And in those cases, the aircraft should not take off. Derek

2,000 ft or 10,000 feet doesn't mean you will be able to exit. A spin at any altitude can mean you will not be able to exit and if the pilot does not recover, you will die with your nylon 'aircraft' on your back. It has happened before. Derek
-
No, you are spot on, Learningtofly does not understand the purpose of the stall horn, which warns of an impending stall because the wing is nearing the critical angle of attack. If the pilot needs to clear trees or powerlines at the end of the runway, hanging on the prop with the stall horn blaring will not produce the best angle of climb, Vx. Derek
-
Just because you have a parachute and are above 2,000 ft, does not mean you will be able to exit if there is a problem, such as a spin. Derek

I think he means the oral portion of the Senior Rigger Certificate test. Derek

This should answer a lot of questions: http://www.airweb.faa.gov/Regulatory_and_Guidance_Library/rgOrders.nsf/0/14c115fcae79293486256ea000572074/$FILE/8610.5J.pdf Derek
