CrazyAl 0 #26 November 29, 2010 Right......... So should all Parachute Associations just banned products with out facts until proven otherwise. That would ruin skydiving completely, and we all know it. Unless there is serious proof of gross negligence most reputable aviation governing associations allow/encourage the manufactures to be present during investigations. In addition they call emergency meetings in the event something may need to be grounded or pulled off line. During these sort of investigations they our known to hire experts from third parties, and have the manufacture present to answer to the product or device in question. Nothing is done based on hearsay, there are way to many legal ramifications from jumping to conclusions, as well as it's just a bad #$%^ing Idea. Can you imagine being an all Argus DZ right now in OZ? If there are any I feel for them, this is not fair and should not be condoned by any skydivers. I'm sure Pratt & Whitney would have a huge claim against the FAA if they grounded all P&W turbines on jump ships because of two engine fires in Europe which had less than adequate proof P&W was at fault.

RiggerLee 61 #28 December 1, 2010 This has been really fun to read. Where was all this fire and fury a few years ago when it was so fashionable to move cutters from their obveous and natural position to a new location above the pilotchute. Do you reallize how many rigs had to be modified? Whole countries passing laws about it. And there were several deaths sited in that and I think there were more unreported. I think I saw one thoue I didn't recanise it at the time. And now you want to go the other way. I feel like I'm in an old cartoon. The one where he's on a board or a rock acting like a sesaw. Running from end to end trying to keep the thing from falling. It's comical. And you say the APF jumps to conclusions. So lets see. You redesigned the rigs to try to correct a rigging error. Then you banned an AAD to try to fix a cutter probblem that might or might not exist. Now you want to ground riggs so that an AAD can be jumped... This is the best entertainment around.

Bolas 5 #29 December 1, 2010 Since making that post, I've been informed that for a cutter "lock" to cause an issue with manually deploying the reserve, the AAD would have needed to already fired. My initial concern was with the AAD interfering with a normal reserve deployment that occurred prior to the AAD firing. While the likelihood of a cutter "locking" is extremely limited the chance of the jumper attempting to pull their reserve at a survivable height after is most likely even moreso. It's simply a matter of non riggers not aware of the possible faiilure mode. Like most I ASS-U-ME-d prior that an AAD cutter had no other possible impact on deployment other than to cut or not cut. This doesn't mean something has to be done to change things, but possibly more known. Stupidity if left untreated is self-correcting If ya can't be good, look good, if that fails, make 'em laugh.

SethInMI 174 #30 December 1, 2010 In the APF report on Argus was a mention of an event in Portugal on 3 Sept 2010 where a rig was discovered with a blank AAD display during a gear check. It was later determined that the AAD had fired, the cutter failed, and the reserve was totaled. This is the scariest situation, IMHO. Your AAD fires without your knowledge (low opening, pressure fluctuation in the plane, etc), the cutter jams, and then you jump the rest of the day with a totaled reserve. (Or until you check the display)It's flare not flair, brakes not breaks, bridle not bridal, "could NOT care less" not "could care less". Quote Share this post Link to post Share on other sites

Yep; I posted pretty much the same thing 7 months ago (after the Polish fatality), in response to a poster who said that he'd rather a loved one have no AAD than an Argus, even if they were at firing altitude and had not pulled anything: http://www.dropzone.com/cgi-bin/forum/gforum.cgi?post=3850162#3850162"It's amazing what you can learn while you're not talking." - Skydivesg Quote Share this post Link to post Share on other sites

They had to switch to a different brand. Tough for the dz, Argus and very unfortunate for the student. Quote Share this post Link to post Share on other sites

Perhaps a simple audible alert could be added to an AAD if it fires. It'd have two purposes: * To prevent a rig from accidently being used if the AAD has fired the cutter but for some reason the reserve did not deploy. * Assist in location of a jumper whose AAD has fired. Would be especially useful if they landed in trees or perhaps water or maybe a night jump.Stupidity if left untreated is self-correcting If ya can't be good, look good, if that fails, make 'em laugh.

koppel 4 #38 December 17, 2010 and the fun is done... so many months after banning the Argus it is decided that QuoteIt is beyond the scope of the APF to independently test equipment used in skydiving and relies on manufacturers of equipment to meet relevant approved national performance standards and that equipment manufacturers approve the fitting of accessories such as an AAD to their equipment ensuring that it does not interfere with the equipment function.

While I tend to agree with you, know that every design is a compromise. Having the AAD cutter at the base of the loop facilitates the scenario of a total caused by binding of excess loop length. To me, it's somewhat 6 of one and a half dozen of the other. If you actually got low enough to have an AAD fire, how much longer were you going to wait before pulling your reserve? And if you are in a situation where an AAD fire is a legitimate save, then probability wise, it's likely best to have the cutter nearest the pin.________________________________________ I have proof-read this post 500 times, but I guarantee you'll still manage to find a flaw.

And if you are in a situation where an AAD fire is a legitimate save, then probability wise, it's likely best to have the cutter nearest the pin. But the semi-pop-top rigs (Wings, Javelin, Dolphin*, Basik Seven**, etc) have only 2 flaps above the pilot chute, and nobody has ever shown they will bind on a too long closing loop. (* Dolphin has 1 or 2 flaps above the pilot chute, depending on how you close it.) (** Basik Seven has no side flaps either.) Besides, on those rigs, it is immediately obvious when the closing loop is too long, as the pilot chute cap does not sit correctly. Contrast this with rigs that have a completely enclosed pilot chute, where it is possible that a too long closing loop has little visual evidence, and has been shown to bind on at least one of them. All I am saying is not to dis the semi-pop-top rigs that have the cutter below the freebag. They haven't been shown to need the cutter higher on the closing loop.

I totally agree. Also, the rigs with the pilot chute under 1 or 2 flaps i.e., Javelin, Dolphin, Vortex, ect have much shorter closing loops, (2 1/4) than those that fully enclose the pilot chute like mirage and Vector which can be +or- 6" Something else that may come into play is when all or part of the pilot chute fabric is packed in the coils of the reserve pc spring like a VooDoo and Infinity.
