     Would you ground this canopy?  

We received this canopy, a Silhuoette 150 for repair. It was grounded by a (the) rigger in Israel. Really!!
Canopy had 400 jumps, by a jumper that might weigh 100 Lbs. She was also told it would have to be re-lined. IMHO, this canopy & the lines are completely airworthy. BTW, he wanted $600 to patch and re-line the canopy.

Different country and different standards?

Or just a very conservative rigger and a very good business person.Wink

It would be interesting to hear what some of the other Isreali riggers have to say about this.

FWIW I'm not a riggerSmile

Are those dimes sewn into the top skin all over the place, or just the three spots?

I would think that PD would keep dimes off the assembly floor.

I really do not think those small holes will affect performance very much at all.

I have flown canopies with holes like that and they work fine...and have had small patches done where I could not notice ANY gain in performance.

Personally i have seen a canopy in worse condition, And have said ok to be jumped. I am not sure where those tiny holes are located. The usual place i normally find those nicks are on the tail section. Are they by any chance located close to the tail of the centre cell? if so i could understand why the rigger might deem it unairworthy. If its not on the tail i would let it go and tell the owner to keep an eye on them.
I would also check the deployment bag and the grommet where the bridle is feed through to see if there iscany sharp nicks there. Also how is the canopy secured go the bag? is it acfrench link or soft links?
as for a reline cant say as i have not measured the line trim.
As for 600 dollars for the work, if a lineset has to be shipped abroad and import duty to be paid it can add up. I know in ireland its 26% and thats the total including the shipping price!
Then depends hos much a rigget charges for a reline. I normally charge 90 bucks

OK, let me be clear. The question "would you ground this canopy" was "tongue in cheek". At least a few of you get it.
It's basically a few pin pricks on a main canopy. It's completely air worthy. Anyone that would try to ground this canopy is either nuts or has an ulterior motive. It's a main canopy!

Agree would nopt ground this canopy,.... from what Ive seen on the pics... as far as lines... id have them measured.... but shes only a hundred pounds... not too much stress forces i feel.. are placed on the lines.... if the canopy snivals alot on opening... maybe... but if not... jump it... those holes are too small to really worry much about other then to tell her to watch them and see if they get bigger.... and still dont see them near a seam,... this is rip stop.... stuff pretty strong... and all... just watch it...observe...just my two cents on this....

For the three issues you showed, no.

As to reline, condition is not the only criteria. Relative length can be a bigger issue, so you'd have to give some more information on that.

Have you done a complete inspection (inside and out)? Ripped ribs, or other internal damage?

Just looking for reasons other than the obvious...

I don't know the rules in Israel, but it could be that the main canopy airworthiness approval is mandatory. No approval = unairworthy canopy.

Our standard for patching is that it has to be larger than a pencil eraser (the one on the back of the pencil....) AND in the high pressure zone.

What amount of pressure is there in the tail of the canopy (I realize "it depends," but a ballpark figure would still be useful for me) and what amount pressure differential is there between the high pressure area and lower pressure areas?

(standardized requirements are a big win here to keep people from abusing rules like those for income - or to keep excessively conservative types from running roughshod over customers/the converse is true also - keeps riggers that are too loose from being flippant about real safety condition.)


(question for the master riggers - If the evaluator has to step back and say "well, the pilot is only 100 pounds" are they already on the wrong side of the discussion if that has any input to their assessment?)

(i.e., for weights that aren't above the max loading limits of course - if the wing is good to 200 pounds, then why should the fact that the pilot is 100 pounds vs 190 pounds matter??)

Mark,

One would expect the pressure to be somewhat equal front to rear after the opening and going forward in a straight line.

A better name for the high pressure zone would probably be "the higher pressure first zone" in that higher pressurization of the cell starts there as the canopy inflates and/changes to flight are made.
(.i.e, turns, dives, etc....)

The name of the rigger who made the initial determination has been left out of this thread, but it is clear that many of us know who he is. No one who knows him would say that he was using his position and reputation to make big bucks, and all of us would agree that it would be especially unfair to suggest that he is crooked.

Smile Hi Ray

Thank you as a "Master Rigger" / "FAA DPRE" & "Aviation Person" for the time you spent trying to put a public stain on a Master Rigger in front of his 3 ladies skydivers from my DZ visiting your DZ & here on DZ.com

I hold my answer for taking a decision if you worth any answer - you don't but the readers / posters does worth it.

Few facts:
*The SIL150 have over 400 jumps BUT this is not the only parameter for reline or the how the lines looks TRIM is the most important factor. (you should know that as a Master Rigger / DPRE)

*The SIL150 has more holes at tail area than you show - you show the white bottom skin but not the NAVY top skin - I guess "Hate blinds the Brain", you might think that the holes are nothing this is your right to think different & it should be respected, I can think different & you should respect that as well & not play in the mud.
*The A lines trim are out of spec. by 3"- 4" in between the A group.
*The LST's & BRK-TOG are out of spec. as well.
*The canopy was not grounded but was on hold for reline & repairs & the owner agree with that
**The SIL150 was left as is = nothing was removed or fixed in case the owner will change her decision.
**If I would like to do "easy profit" based on the owner "yes please do it", I would remove the lines & repair the canopy a day after & wait for the new line.

The Story:
The owner of the SIL150 came a said she had some deployment issues, after talking about packing ,line dressing in the rubber bands & so on I checked the A lines trim inside the A group & got a "nice" result = up tp 3-4" in between the lines & 4" between A1 (center) & A5 (outboard) the owner was advised based on all the info. that the SIL150 better be relined before a deployment might hurt the owner or ended with line twist which might lead to a cutaway = reserve deployment - free bag & p/c lost & maybe main canopy lost but most of all self hurting or damage.

The owner was advised to let me run a full inspection before line set order from PD. during the inspection I found some small impact points at the tail area which we see all time at that point BUT also found few holes bigger than 1 ripstop box both in the top skin ZP (Navy) fabric & on the bottom skin 0-3 cfm white fabric.

The owner was advised that IMO the holes might grow up & a major repair might be needed & better be repaired at reline time when all ilnes are removed & surface cover patch will be used.

The owner was advised on few ways of repair & costs.

The owner agree to reline & repair the canopy after knowing the costs of the: (Reline work have a fixed price not including the lines)
*PD lines kit + SM-1 slinks + shipping & import duties + 16% VAT tax, now 17% (payment of the lines is made to the DZ shop - not to me)cost here are higher than in the USA.(yes, I replace the original slinks when I reline the main)
*Reline cost which covers: full inspection, small seams repairs if needed, old lines removal, new lines material, sewing & trim & slinks inspection, reline process,pre-sewing inspection, after work inspection attached to risers.

During the time I spent to find the best, low cost repair for the canpoy I was told the canopy is for sale & she got 2 different mains - 135 sq.ft for few jumps & a ST.120 she owns now - the SIL150 was not sold here. BTW the owner said few times that she want to sale the canopy after being fixed & relined.
The owner took the canopy with her to the USA without any work done for sale it as is.
*Her lines set was sold to a skydiver with a SIL150.

**Few facts for the readers/posters who doesn't know me or met me:

*I'll never use my position to do extra money - I earn my living from skydiving & rigging & my prices are fair even the costs here are much higher by any mean - I do not use USD I use Israeli Shekels !!
*I'll NEVER advise skydivers to go into a process for my own profit if they don't need it !!
*I'm giving my customers the best PRO care I can offer based on the Mfg. Instruction & all the years I study & still study at all time & yes, I do respect the Mfg. instructions - I have issue with any mfg. instructions I deal with the mfg. but I respect.
*I'm spending a lot of time & money for studing, all PIA sym. since 1995 & PIA meetings before the sym., running rigging classes at the PIA for many years, always a part of the PIA/FAA "Riggers Education" program & I'm the only civil rigger from Israel doing that. Most of my income is from skydiving & DZ rigging I do.
*I visited h/c & canopies mfg. & spent time to learn more & keep update my education.
*When I find a rigging error/s I try to trace the rigger & share with him my findings & educate for the right mfg. way to do it.
*I provide my customers a FREE AAD when their personal AAD was sent to Airtec.
*I provide my customers FREE main & reserve canopies when they have an issue with the main or reserve.
*I can be after a jumping day & a customer will ask me to I&R his/her reserve for tomorrow & I'm doing that - I NEVER charge more - I do it as a service even if I have to stay later or wake up early - same for repairs if can be done at that time & keep a customer airborne - NEVER charge extra.
*I spend hours with skydivers at No Charge when they order a new rig (I do not sale) or want to buy a used rig. when ordering a new rig I measure & do all the technical work FREE !!!
*I do NOT charge when I put an AAD into a h/c or replace batt. in Cypres1 if it is a part of th I&R process.
*I do not charge for main closing loops but give these free.
***I know my limits as a Master Rigger & when things are not clear to me I contact the mfg. for advise - I do not use the "Over Power given to me by law" I know my certificate rights but also the LIMITS.
***I do all I can for my customers for having the best Safety & Care when skydiving.
*** Yes, I have my own points of view & standards when I practice rigging you can agree or not but this is my way.
***I put all my forces when I think that my customers deserve a WARRANTY repair or service from a mfg. for having quality / mfg. issues & there are - I do that for the owners Safety & having the correct items which they paid for.

MAIN CANOPIES ATTITUDE:
Being a MAIN canopy doesn't mean the care should be "Wild" or careless, it is a parachute that is exposed to multi use conditions & care should be taken as well. Not being a TSO'd item doesn't mean it is in the "Wild West" area. you in the USA hve your own point of view - other countries (yes, there are others in the world Wink) that have different points of view - respect that.
** you might have the best h/c, the best AAD, the best reserve BUT if your main or a main part will fail at a very low altitude nothing will help you - the only thinking will - does that incident could be eliminated by inspection & care ?

A POINT TO THINK ABOUT:
The Xaos27 SB for the 2 shorter lines (mfg. error) which left a skydiver injured - it could be found during inspection & line trim check & the incident might be eliminated.

The saying & education "It is only a MAIN or a Non Approved item" is so wrong & might hurt skydivers all over.

*** Each issue in a canopy/parachuting system could be advised different by different riggers but all should be on a PRO basis & not Personal basis.

* Mark - thanks for the support & knowing who I am.

Thank you Ray - as I told you before you want to be respected - respect others !!! You put a stain on yourself & yourself only !!!

Be Safe !!!

Smile Hi

The post is: Would you grounded this h/c ???

Few years ago an Israeli skydiver visited a DZ & a gear shop in CA. & bought a full rig which was ASS. I&R at DZ's loft by a rigger.

He came to our DZ happy to jump proud of his new rig - the rig got a pre-jump inspection & packing date card check.

Findingson the h/c & after getting the reserve cost info. from the owner:
*The skydiver was charged US$400 for a 20 years 2 month old Firelite R without any written history - only the last Ass.I&R (All FCI's reserves should not be clamp tested by FCI's instructions)
***The owner didn't has any idea on that.
****Same rig was with an AAD BUT the reserve loop was OUT of the Cutter Hole !!! I know it will not stop a manual pull of the reserve ripcord but the AAD will do ZERO if needed.
****The Reflex h/c had a mandatory SB on the TOP main container flap grommet after a fatality happaned in CA. The SB on that specific Reflex was made WRONG = position of the Ty.17 dimple & the use of a SHORT SHANK #0 SS grommet instead of the LONG SHANK #0 SS grommet & washer.
****The reserve ripcord cable was found 2" longer = 2" below the bottom leg of the "D" handle.
****The Reflex external reserve p/c was free & the main parachute line could snag under it.

I trace the rigger & talk to him - he was a great person & had the willing to learn - really nice person.

***I gave my opinoin to my customer free of charge even I spent hours on that.

This loft from CA USA provided a skydiver a RISKY system in the way it was served & charge for that "Rigging Work" good money !!!

Myself & the DZO / Shop owner used to be friends, I even visited him there but after talking to him about this subject he turn his friendship to dislike position. (I'm using kind words)

Would you grounded this system & fix all before next jump or jump it as is ????

Safe Rigging !!!

S~,

Thanks for the complete write up.
The description as given by the OP did not, in and of itself, give any reason to "ground". (the OP's question)

This sounds like a much more complete, rational, reasonable summary of what was found and suggested.

While two professionals can do a competent review of equipment and come to two different decisions on assesment, recommendations, repairs, quality and price, (especially when they are from different areas/countries) it did not seem to me that the OP's summary would fit with what I have seen of your approach to rigging.

A little courtesy would have helped here, one rigger talking to another if the one had serious issues with the other's work.

Still, the circumstances in this case are interesting to read, as they show how riggers can differ in their opinions about gear, that there isn't always one answer.

In reply to:
We received this canopy, a Silhuoette 150 for repair. It was grounded by a (the) rigger in Israel. Really!!
Canopy had 400 jumps, by a jumper that might weigh 100 Lbs. She was also told it would have to be re-lined. IMHO, this canopy & the lines are completely airworthy. BTW, he wanted $600 to patch and re-line the canopy.

I've bought several old canopies with much worse wear than this - including a Stiletto 120 from Action Air. I sent it to PD for a reline, patch repairs & inspection. Came back with new label on it (so I then could read the DoM - 1994 - and the serial #). I don't think there was much change from $600 (incl shipping and tax). I asked PD how many more jumps/use could expect. Reply was basically unlimited if properly cared for and maintained. I've put 500 jumps on it since, still seems fine, flares perfectly well. So...I think the Israeli riggers inspection and estimate are reasonable (I'm not a rigger & I'm lucky enough to be able to afford all necessary repairs)

Disclaimer: I am not a rigger, just a skydiver that trusts some of them with his life, well being and the future of his family.

Since I didn't notice RIGGER's name mentioned here yet I wont be the first to use it.

I did my AFF and first 1200 jumps working and fun jumping in RIGGER's DZ and consider him to be (among other great instructors at that DZ) somewhat of a father figure as far as my skydiving career is concerned. I have since moved to the US, but I wanted to give my take on this as a former costumer, as it is not the first time I heard complaints here and elsewhere, and to be honest at times I was frustrated with him myself (you know I love you man :)

I will not speak about his competence as a rigger, as I am not in a position to pass judgment in that respect. I will say everything he said about his costumer service is 100% true and correct. I can not count the times I saw him repack a deployed reserve long after everyone has gone home but those that stayed over for the night or live near the DZ, or walked into the DZ early in the morning only to see that he has been there for hours repacking due reserve that expired or were deployed the previous day, not only so that we could work or fun jump immediately the next day, but so we wouldn't even have to miss the first load. I have personally seen him almost miss a flight (to PIA symposium I think) to assemble a temporary system for me to jump during his absence after I deployed my reserve on the last load of the day of his flight, all so I could keep working while he was gone (parts, labor and use of gear free of charge BTW). And it is very true that he never charges extra rush fee, but still gives immediate service almost always when possible. And I have yet to see a single DZ anywhere in the world where the rigger provides unlimited rubber bands and closing loops free of charge no questions asked like he does.

His fees are easily comparable with US prices even though everything in Israel is significantly more expensive and the taxes are high. Of course materials and parts are more expensive, but that's due to S&H and taxes.


I could go on, but what's the point. Just wanted to chime in as a costumer and say that while his PRO attitude is a common thing for many riggers (that I have met at least) his level of care and honest attempts to be helpful (within his standards of safty, which are higher then what some skydivers would like) is rare, and I for one am glad to have had him as a rigger and an instructor, and would give him back my business in a heart beat.

In Response to: RIGGER
The post is: Would you grounded this h/c ???
------------------------------------------------------

The rigger that made this mistake (closing loop not through the cutter) went through retraining after this incident, then decided to quit rigging. So the problem was address and handled.

The jumper wanted an inexpensive rig, which is what he received. As far as the equipment was concerned, it was completely airworthy.

The rig owner was not allowed to jump this rig in Israel. I ended up refunding the owner his $ for the H&C, reserve and Vigil AAD (because RIGGER would not allow Vigils on his DZ). I provided him with another H&C and sold him a PD reserve and CYPRES at cost to help him out, so he could jump in Israel.

Trying to justify your BS by diverting attention to a what - 4 or 6 year old incident is lame. But it may work for the uninformed. Good luck.

No approval = unairworthy canopy.

= big bucks for a rigger willing to unfairly exploit any 'approval' rule
I never though rigging was a way to make big money......unless you're crooked

(standardized requirements are a big win here to keep people from abusing rules like those for income - or to keep excessively conservative types from running roughshod over customers/the converse is true also - keeps riggers that are too loose from being flippant about real safety condition.)

The name of the rigger who made the initial determination has been left out of this thread, but it is clear that many of us know who he is. No one who knows him would say that he was using his position and reputation to make big bucks, and all of us would agree that it would be especially unfair to suggest that he is crooked.

thanks for the info - no intention was there to bash anyone specifically....

my comment was a generalized comment about any type of undefined rule that would allow someone to ground a visitor for any reason. thus the comment on generalized standards was real though. Good thing we have them.

Not at all since there is no holes and the little bugs (two) are small as well. It looks like the fabric has been caught in barbed wire and/or squeezed on metal. Any rigger should understand that this is why ripstop is the material generally used in canopies construction. RIP STOP means it will STOP the RIP Madespecially the small ones. Easy enough to understand. Better yet, those little bugs would be OK on a reserve too because there is no holes I can see bigger than 1/4".
But OTOH I am not surprised : One time I asked to a very experienced and rated Israeli rigger what i needed to know if I wanted to go and jump in Istrael. Since they have a DZ below the sea level, it looks cool to me to make a couple of jumps there. 1) The answer was actually a question : What country are you from ? Skydivingly speaking...irrelevant. 2) we will check if the size of canopy you use is OK with your weight...I answered...even if I have experience with it...the answer was...yes.

To come back to the thread subject, as a rigger, if I would see such thing, I would mention to the owner that a scratch or hole on a canopy fabric never get smaller with use. I would also say that everything so far is OK but since your lines have 400 jumps and there are few bugs on the fabric, to keep a eye on them in ordre to control the evolution of the wear and bugs. That way, I give a sound advice not too drastic and put some responsibility on the jumper shoulders instead of trying to keep an absolute control by telling NO.

Sorry for the thread drift, but... their country + their DZ = their rules. Some DZ's in the states require you to have an AAD regardless of your experience, others restrict how you can fly your canopy regardless of your experience. Don't like their rules, no problem... don't jump there. Really want to jump there, but follow your own rules, start your own DZ.

Yeah, one of our instructor stopped a New Zealand jumper from boarding with his go pro last weekend. He had all of 10 jumps, no clue how to turn on a cypres but was very miffed that he wasn't allowed to jump his fullface + gopro here "as he is allowed to jump it in NZ"

Are you sure of that when you say the high pressure is located on the last 1/3rd of the canopy at the tail.

Why then Performance Designs asks us riggers to perform fabric tensile test on the tail (3 sec. 3 locations and 30 pounds away from any seam or edge) ?????. When a canopy inflates, the highest force is located on the canopy first third (the nose and a couple of feet behind) so is the pressure. If a line breaks, this is very often a A line where to force is the most intense.

I think in this case, we don't really have a problem of regulations but WE HAVE an attitude problem. It is not because you are a doctor that you know everything even if you give the patient tons of explanations.
You have to be like a scientist ie. a good engineer. Assess the situation objectively, don't let your personal preferences color your judgement and give an advice which cannot be criticized. Not always easy.
With such an attitude, no old airplanes even well maintained would fly. BTW I jumped recently from an Antonov An-2 designed in 1937.Wink

Everywhere you can see power trip and abuse of authority even seemingly about what brand of AAD you used. This is not the way to lead skydiving. And remember, I said, I am not surprised...that's all. And I know who is the rigger.

Positive of it.
Simple physics applies here.

....Probably because the high pressure zone is going to be the first area to blow out if the fabric is weak.

You are confusing canopy pressurization with canopy load.

... Two very separate items!

I understand that at inflation, the air rush inside the cells and is blocked at the tail seam which is maybe why you say that this area is submitted to high pressure. But what is the main cause of tear in the fabric at inflation...pressure or force (load) ? From my point of view, since the tail is down (on brakes) at opening, the first part of the canopy near the nose (outside and inside) is behaving as a round parachute creating at this moment a very high pressure on that area and load as well. What do you think about this explanation ? On the other hand, I always thought that PD were asking us to test the fabric near the tail because it is the less critical area. I would rather have a hole in the fabric near the tail than near the nose !!! Thank you for your interest...I am going to do some researchWink

It is not maybe why i think that. It is exactly why I know that!


Quote:

It depends on a lot of different things.
One of which could be if the fabric was damaged or burned beforehand or during the same deployment.

Line burn is the number one cause of "blowouts". JFYI.

A distant second is weak fabric from age issues.

The next tine that you remove some lines off of a canopy please note that the center "C" lines will probably be the hardest to remove from the line attachments.

Your theory is skewed.

MEL -

How could I find out the amount of internal pressure created inside the tail during inflation, and how that compares with the internal pressure in the rest of the canopy?

What is the source for the fact that line burn is the #1 cause of blowouts?

Do you think the tightness of the center "C" line larksheads is a result more of forces during internal pressurization than because of, say, lower-surface inflation earlier in the process?

If the "C" lines take more force, then is it a myth that the lines most likely to break during deployment are the center "A" lines? Should Precision be switching to continuous "C" and "D" center lines instead of just continuous "A" and "B" lines on their reserves?

Thanks,
Mark

Rey,
I think you can stop now,
You said already more than enough!!! (or should I say "not enough"... details on the original post)

I know RIGGER since 1987, from my military service as a jump muster and from 1993 we are working at the same DZ, here are some facts:

- He is the most strict and honest person I ever knew.

- All he wrote about his costumer service is 100% true and there is much more.

- Yes, he is old fashioned, from the days when being honest, fair, professional, a real friend and polite were considered to be good.

- Yes, he will ground equipment that other riggers will not, BUT he will do it only for the sake of safty!!! never for his one profit, and will always choose the safe side.


On the other hand - You mr. Rey,
I know you only from the original post....
and I didn't decide what is worst:

- Throwing mud on a colleague by posting half-truths,
OR
- Not being able to see all the things RIGGER did...

You can guess who will do my next I&R :)

Be safe
Gilead

P.S
4-6 years ago RIGGER didn't post a nasty and offending post on D.Z.com.... Blush
Or may be you are just looking for revenge??? Mad
Hey - after 4-6 years this is all you got..... you must be kidding TongueTongueTongue

Cheers
