Ah I remember those cushions.
We replaced them, and they were in poor condition. Not just the covering fabric 
but the underlying material.
Unless I am wrong the core material resembled Coconut Husk or similar.
In fact Wolf Hoffmann was spot on with his material selection at the time.
Now we have good synthetic alternatives.
Personally I think the original material still cuts it for impact absorption 
without bounce.
If it aint broke don’t fix it.
Of course if redressing the aircraft then use the Confor foam as Macca mentions 
as it is good stuff.
I still find it hard to believe you have a H36 with only 110 hours on it.
Bet you can’t get it to life limit in your lifetime.
Heather and I can’t do it with ours and it already has 2700 hours on it.
Cheers.
Nige.

I Ian,
 
I have a H-36 only has 110 hours of flight time (many years has been stored in 
a hangar). Stained the original seats, as you can see from the photo, it is 
possible that these seats are not safe?. I have to change them?

I bought a pad of green from a guy in WA who John Viney recommended but you can 
get pads of blue (just a little softer) from Aircraft Spruce in USA  

I find the h36 cushions uncomfortable for me - those horse hair ones.  I have a 
mold seat for a Falke and I took segments out of this mold to make a new seat 
for RH of Dimona and added confor. I find it great - the space between my seat 
and the dimona seat pan is filled with 2 pack PU foam.   The bonus is less 1kg 
in weight also.  I am not proud of my glass workmanship on this one but next 
one will be better.  I think you need the good shaped seat (even built of VERY 
hard carved foam)  before you add the confor. It all take time but you can not 
put a price on a good back.  

Guess cost inc post from USA per seat would be $70 as a guess - think a bit 
more from WA was $220

I look back on that hk36 that was with the other club here and pranged in 
trees/creek and it had nice soft yellow original cushions but if Tom had had 
confor cushion he may not be in a wheelchair today 

Guess 8 years ago JV gave me a demo of 3cm of foam on a brick wall and punched 
as hard as he liked and did not hurt. That started my campaign.  Jab Falke XJX 
here has shaped seats (5 layers of 92125 cloth per Katja instructions at 
Scheibe) with 25mm layer of green Confor.  Today I would love to use 
carbon/kevlar but all Katja tells me we have them for think Eur380 each bur no 
layup.  The original seats were terrible - flat sheet of ply!! 

It is great to see BGA re campaign on confor use in all gliders and the real 
add is how after the crash that guy got up and walked around.

  Hi Ian,
  An interesting article.
  Can you advise of suppliers and typical costs in OZ?

  This article from BGA is very worth a read.  People who saw the crash may 
remember after crash he just got out of glider and walked around and I love his 
statement.

  Kiwis must have confor in their gliders while the Poms highly recommend it 
and most club gliders have it.

  I personally believe it should be mandatory in Australian gliders and just 
maybe one person who is now in a wheel chair and was sitting on crap makers 
yellow foam cushions may be walking today.  For those that know confor foam 
give the demo of slamming your fist into 3cm of confor on a brick wall to your 
friends.  

  As many who know me know I will never sign out a form 2 unless it has confor 
foam cushion. (nor will I sign out a crap hard to read Altimeter or an 
undercart without decent green -down and red -up) 

  Lets hope there are a few more AUS gliders using confor cushions this season 
ou from a wheelchair.

  Treat cost of confor foam as a one off insurance policy which may save you 
from a wheelchair for the rest of your life.

  To: BGA Full and Assistant Instructors

  You will be aware that BGA RP 38 recommends that all glider cockpits should 
be equipped with cushions containing energy absorbing materials.

  These cushions are widely used in club gliders but less so in privately owned 
gliders.

  The BGA has produced a booklet explaining how safety cushions work and how 
they can reduce injury not just in a crash but in the heavy landings that occur 
from time to time on instructing flights. We are hoping the booklet will 
encourage all non-users to install energy absorbent cushions.

  You can download a copy of the booklet from 
http://www.gliding.co.uk/bgainfo/safety/documents/safetyfoam.pdf and your CFI 
has hard copy versions of the booklet for distribution.

  An EMail highlighting the issue and providing a link to the booklet will be 
sent to all private owners in the next few days.  Please help us by encouraging 
all pilots to fly with a safety cushion.

  Best regards

  Peter Claiden
  Chairman, BGA Safety Committee
