Because the DHT "reserve" is practically just another main canopy the packjob itself is VERY easy. Quote Share this post Link to post Share on other sites Zahry 0 #79 August 2, 2009 If anyone thinks there is nothing wrong with the system. Here are some photos of the disputed design. The parts were inspected on friday (25 jump check) and since the inspection we did 7!!! jumps only on the equipment. During the inspection there was no visible damage to the loop, plastic, housing or the stitching. Today morning when I did few random checks I've discovered the damage. What you see on the photos is the housing cutting its way out through the plastic. How does it happen? The 3 ring system in certain configuration in freefall can push the housing into the plastic. The housings are mostly improperly finished (just cut with exposed sharp edge - every single one I ever seen is almost the same - some worst, some better) and when pushed into the plastic the vibrations from drogue can help cut it its way through. And if there is rough sharp edge (just like in our case here) it goes through like a chainsaw. On the Detail you can see bit of the loop still caught on the rough edge. It looks to me not just like only one design flaw but a whole bunch together.This rig has about 1 500 jumps and the housing was changed 3 months ago (the numbers are from top of my head - the exact numbers are recorded in maintenance book @ DZ. If anyone is interested I can provide the exact number of jumps, mothly average and DOM) I think the same thing in worst stage killed the czech tandem pair. When I've asked czech autorities about the other two accidents Tom mentioned I've discovered there was only one accident involving housing on risers jamming cuttaway (TM cutted the riser loop) and nobody knew anything about the other two accidents Tom mentioned in this forum. - maybe it was just misunderstanding and it happened somewhere else ... but there are other disconcerting fact. I found out the reserve packing card has been provided to Ted and Ted has been reminded he has seen it before publishing his press realease - and than he stated he hasn't seen it (you can check it with czech autorities as well just like me) So, can I trust the rest of it what the SE says? Also, I was unable to find where the DHT manual states the owner must keep inspection and maintenance records other than usually found in reserve packing card. (I was unable to find where it states the rig has to be sent back to strong after 8 years as well - but it might be just my fast reading ...)

The factory inspection is written on the reserve canopy's packing data card and stamped on the original TSO label. If the original TSO label is faded, Strong Enterprises often sews on a new label stating the date of the 8-year inspection and reminding owners of the date of the 13-year inspection. After 18 years, all Strong Dual Hawk components are retired. Some of these inspections are just common sense. No-one expects a main canopy to be sent back to the factory for an 8-year check because no-one expects a main canopy to last more than 1200 jumps and if you have not made 1200 jumps (150 jumps per year) on your main canopy, you are in the wrong business. Similalry, the 8-year inspection was introduced after we realized that most Dual Hawk Tandem containers were looking faded, frayed and filthy after 8 years service in the California desert. All that desert grit and harsh sunlight wears out nylon containers rapidly in the Southern California desert.

Writing all you think & findings on the forum & still move on with no action might be back to you if an accident will happened at your DZ. I do not know which mains you use in the DHT's better be SE approved mains. I wonder why your DZO still use these rigs after you the DZ rigger point on the hazards ??? You better think twice on your actions with the rigs with the present housing. Do not do the best you can - take an action or just back off !!! words or rigging / jumping. If some NZ riggers reported to SE & still move on with the same issues = I can not understand that. Does $$$$ are in front of SAFETY ???? What the NZ Skydiving Association or NZ CAA are doing about ?

Quote Share this post Link to post Share on other sites riggerrob 643 #97 August 7, 2009 QuoteAre these hand tacks the only thing stopping the bendix from sliding through the keeper? >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Yes! ...and if riggers are smart/neat they do replacement hand-tacks deep in the grooves to reduce the risk of flexible housings sliding. That technique has worked great - for decades - on ripcord and 3-Ring housings. Modern trends towards Oeteker clamps have been merely to reduce the amount of semi-skilled labour and time in manufacturing. Sometimes the worst thing with semi-skilled labour is that they "invent" new hand-tacking techniques without understanding the bigger picture. Reference the Service Bulletin from Para-Phernalia about the correct spacing between ripcord housings and the grommet.

No rubber bands or shock cord (bungee) on the Atom reserve system. I'll try to find a photo. Cheers !!!

RIGGER 0 #89 August 4, 2009 Thanks Tomas. I got your points & thanks for the report. If SE does not gave you any answer or solution that you as a rigger & TI can move on with it you should STOP the rigs. Writing all you think & findings on the forum & still move on with no action might be back to you if an accident will happened at your DZ. I do not know which mains you use in the DHT's better be SE approved mains. I wonder why your DZO still use these rigs after you the DZ rigger point on the hazards ??? You better think twice on your actions with the rigs with the present housing. Do not do the best you can - take an action or just back off !!! words or rigging / jumping. If some NZ riggers reported to SE & still move on with the same issues = I can not understand that. Does $$$$ are in front of SAFETY ???? What the NZ Skydiving Association or NZ CAA are doing about ? All was said is regarding your info. only & what you show & write about. You better call Tom Noonan at SE for a personal chat on the housing issues - he will listen to you. Be Safe & Smart !!!

mickhardy 0 #90 August 5, 2009 Zarhy's third photo is pretty scary. On the accident rig, it looks like the entire housing is free to slide before emplaning. Zarhy does have a valid point about out how this failure can be accelerated. Quote Share this post Link to post Share on other sites
eric.fradet 17 #91 August 5, 2009 On conventional freebags the force necessary to pull out freestowed lines is almost zero and once the first closing loop is pulled out running loop releases the pressure and there is almost no force needed to deploy the other one ...... THERE IS NO SAFETY FEATURE LIKE THAT ON DHT ------------------------------------------------------------ for your knowledge the Atom tandem reserve bag from PF/Aerazur also does NOT have any running loop but an elastic band to hold EVERY stow, similar to the DHT one, and I can tell you it works pretty good so far, Atom Tandem is very popular in Europe Quote Share this post Link to post Share on other sites
RIGGER 0 #92 August 5, 2009 The PdF "Galaxy" & "Atom" tandem free bag system is way different from SE DHT free bag. This is more like a "High Speed" system. Yes, it works well & lines deployment is in order. Be Safe !!! Quote Share this post Link to post Share on other sites
RIGGER 0 #93 August 5, 2009 Thanks. Tomas does have some valid points BUT he should deal with SE & if he does not have any good answers just STOP the systems till the best solutions from the mfg. CZ fatality is from a line of errors all around the process. Safe Jumps !!! Quote Share this post Link to post Share on other sites
