Main re-pack

[northcave 0]

Just wondering if there is a maximum time that anyone would leave their main packed up for?

I havent been jumping for about 4 weeks and my rig is still packed up from last time. Would anyone here re-pack their main if left for a certain amount of time or does it not matter?

Doesn't your BPA have rules for this? Most countries have something to say about repacking a main, usually it's the same length of time as the reserve I think, so 4months-6months. 4 weeks is nothing Unless it's been wet (shouldn't have been packed unless jumped again right away) or you need to practice packing LOL

Oh BTW you list a PD150 reserve which does not exist

As far as I know 4 weeks shouldn't be a problem. Should be a nice snively opening

Yes, I do. If I feel any doubt and have time I repack my main. Its not because any regulations its just because of me. I love to feel,touch and pack my canopy.

It should be fine after four weeks.

In the United States a main must be repacked every 120 days, the same as a reserve. If you are really geeky, you can read the specific regulation at 105.43(a). Your country may have a different regulation.

As a general rule, a parachute will pack and then settle just a bit. Most of that settlement occurs over the first few hours to days. From there it remains pretty much stable in the container, and opening performance doesn't change much as long as the rig is well maintained. If it sits in a car trunk in the bright sun there may be problems, but generally, once a rig is packed it remains fine to jump for at least a little while beyond conventional mandated packing cycles. I don't have quick access to the data about packing changes over time, but I know somebody else here might be able to post it.

The main reason the United States has a 120 day repack cycle, and other countries have repack cycles, is to allow for inspection, an increasingly important point with more rigs equipped with AADs that have batteries. For that reason, inspection, I'd strongly encourage you to follow manufacturers and regulatory guidance about repack cycles.

So, you should be fine jumping your main four weeks after it was packed. If you want to repack it, go ahead, but don't feel obligated.

After 4 weeks? Why?

Left mine for ~4 months once. Longest 4 months of my life

Was just thinking that after 4 weeks all of the air is out of it. Should open nice and slow.

4 weeks that is it? A friend of mine quit jumping in 1998 and his Sabre 150 has now been packed for almost 10 years

If ya feel uncomfortable, re-pack it, at only 25 jumps you could use the practice. Before you repaci it though, jump it, it'll work...

If it went more than 5 years I'd definitely repack it! Every 120 days is probably a good rule of thumb if you want to be careful.

George G did some tests a while back where he packed up reserves, let them sit for X years on a shelf, then test jumped them. Last I heard he was up to 6 years; no problems other than a slightly longer opening time.

Rubber bands deteriorate with time. Might want to check them. Also, if the rig was stored in a hot or damp area, best check it more frequently.

For the heck of it....back in the late 70's we jumped some static line T-10's that had been packed for close to 20 years and they all worked.

I often repack the PC before I repack the main. I like that ZP PC not to have taken much of a set. Get the rest out of the bag and I'm good to go.

IF it's out of your control I'd be more cautious.

But shoot, 4 weeks is a weather hold!

I had a reserve ride on a borrowed rig back in the 80's and afterwards we discovered it had not been repacked in over 4 years. (I think it was a 22 ft. sac)

Some people say that the material is different now...Well hell yeah it is different, It's better!


I honestly don't think parachutes know how long they have been packed if they are stored properly. Time alone is not a factor.

Hi northcave,

Why wait? Email your serial number to PD & they will tell what you have.

Then you can 'inform' whoever packed it/filled in the data card.

Never noticed any difference at all after that length of time.

How many jumps does it have?

If it's new (under 100 jumps) I personally never let it stay more than 1 month packed. I repack it every month. My brand new samurai was packed for 1,5 month, and when I took it out it was all sticky and kept almost the form of the bag =(

If your'e in doubt..repack it and inspect the rubber bands and linestows. It takes 20 min... Personally I think it's worth it. =)

I repack every month just for practise. As BillVon says there have been tests where mains packed for years opened just fine. If it does however concern you then it really isn't that much trouble to repack before jumping.

Right, but who cares? The important thing is that it opens - and taking a bit of a set won't keep it from opening. About the only argument I've seen is that the material can start to adhere after a long period of hot storage (like the red cordura on some 2002 Javelins) - but I have never seen this be an issue on canopies.
