Parachutes again

Yes Bill, I agree. I jumped just 2 years ago a main canopy which was
seating in the deployment bag for 4 years. I new I packed it, remove
the risers from the harness/container and had it in my packing room.
Then one day in the evening I was to lazy to pack my main so I grabbed
that old Raven II I packed over 4 years ago. No problem. It opened just
fine. But in the case of skydiving we all have a second parachute on
our backs. We are not questioning if the equipment will work or not.
The point here is that the regulations and the manufacturers
recommending repack and inspections every 120 days. And for other
people...it is not 4 months, it is 120 days. Now, whether the parachute
is good after 120 days or 180 days it doesn't matter. Unless the FAA,
all of the manufacturers and PIA will change the repack cycle to 180 or
360 days, or whatever the interval might be, right now it is 120 days.
And if the manufacturer is putting on their equipment a life span, well
that is it. End of story.
Now, I have seen in Oakland, CA pilot going to fly acro in his Super
Decathlon ramp checked. His parachute was out of date and the FAA
suspended his license for 60 days. I don't remember if there were any
monetary penalty as well or just the suspension. Similar situation I
witnessed at the non existing anymore glider port in Fremont, CA. But
the violator was an instructor so the penalty was much more severe.
Besides having his license suspended his instructional privilege was in
jeopardy. Since this was in like 1986 I don't remember the particulars,
maybe that person is posting to this group and could give us some
better explanation.
And now, like a rigger to rigger...would you pack for someone a 39
years old canopy? or 27 years old canopy? I would not. We riggers,
are not just a bunch of stuck-ups, we are just like the A&P's and the
AI's with the main difference that instead using aluminum, wood or
composite we are using fabric, webbing and line. The data shows that
the fabric is degrading while packed in the container at the rate of
about 3% a year. So, 3% x 20 years = 60% loss in strength. You now as
well as I do that you can grab the F-111 fabric, which most of the
emergency canopies are made out of, and you can pull as hard as you can
and it is O'K but move your grip a foot in any direction and you will
tore the fabric with a minimal force. Performance Designs asks that
after 40 repack cycles the canopy being returned to the factory for
evaluation. Why? Because it degrades!!! And the same is true for every
single canopy especially those older then 20 years.
So guys and gals.. you can argue as much as you want but the regs and
the industry would have to change dramatically. In the mean time it is
120 days or fly without a parachute.
