Really tight main pin

Recommended Posts

I have my temporary main really stuffed into my temporary container and while we were able to close it the pin is SUPER tight. Now I only plan on doing hop and pops on this thing so would you share your opinions on how tight is too tight or whether this will be a safety problem. Thanks. Always appreciate it.

I good pilot-chute puts upwards of 75 pounds of force on the closing pin.

Is your pilot-chute in good shape? Also, is your closing pin free of any knicks or scratches that might cause it to hang up?

My understanding is that closing loop tightness is a compromise between 2 extremes (1) too loose causing premature pin release resulting in premature deployement or horseshoe malfunction, and (2) too tight resulting in pilotchute in tow malfunction and reserve deployment jeapardised by main PC.

There are various elements that will affect this, these are the ones I can think of:
1) Do you freefly? Freeflyers expose the closing loop and bridle parts of the packed rig directly into a 150mph+ airstream. A good RW (flat) flyer who doesn't go unstable will have these parts of the rig in his burble on his resulting in less force on the systems and less chance of premature. An unstable RW flyer may expose the rig in the same way as a freeflyer.
2) Is you deployment system BOC, leg-strap or pull-out. How much bridle is exposed to the airflow by deployment design.
3) Is your a modern rig with much or all of the bridle covered from direct exposure to airflow.
4) How well does the main flap protect the pin, and how carefully do you move around in the aircraft. There are some 4way RW exits that have the floaters pushing their rigs against the top edge of the door.
5) What shape is you closing pin. I notice that some throw-outs have curved pins shaped like a "9" and some have the circle of the metal meeting the pin more centrally, say like a "T" with the top edge curled up to form the ring and the drop line bent one way. I suspect the latter shape is more likely to PC-in-tow if you push it all the way into the closing loop rather than the recommended 1/2 way in.

My own philosphy is that it if I don't have to jump on my dbag with my knees during container closing then my loop is too loose; but I'm a freeflyer and I'm paranoid about closing loop tightness and bridle exposure. You will probably get a more informed and better qualified response from a rigger.

Same here, Rich. If I'm not cursing, the pull-up cord is not about to saw through my flesh, or didn't break a sweat from wrestling it, then it isn't tight enough.

:o I had the same concern last April. I was jumping new gear (Mirage G3, Saber 170, a tight combo when new) and the closing loop was real tight. I had planned on doing a hop and pop from 6000. I threw my pilot chute almost right off the step and low and behold .... no main. I looked down and grabbed both my handles and then paused ....... thought I'd give myself another 10 sec since I was still fairly high. After another 6 long sec. my main deployed. I really got teased when I got down, "I have never seen a regular sport rig with a drogue!!".

My old equipment was so loose I could depoly after leaving the step. The new gear required much more snatch force to remove the pin. Just something to keep in mind. Hop and pops are great but give yourself some altitude ..... you never know when you may need a few more seconds, especially with new gear!

I thought the "standard" was 10lbs of pull, if you're even slightly pulling a rig off the ground (since rigs weigh 20+lbs) then its too tight.

Am I correct with the 10lbs or is it different?

aha, couldn't agree more... :)
I was jumping an old SweetHog with roll on leg strap (if that's it), made 300 freefly jumps with it, and that's why my closing loop was very tight - sometimes i had to try twice to close the bag.
I'm not saying that this was the main cause why I never had problems freeflying it (I was stupid, no no, I was idiotic - but I LOVE FREEFLYING!!!! couldn't help myself, couldn't borrow equipment all the time...), but surely it contributed a little bit...
