| Subject: | Re: ******* Fire hazzard ***** |
I don't want to get into silly "non-disclosure" discussions but it is clear that
there are those who are aware of the potential for sun damage to the glare shield
and those who are (or were) not. It would help if those who knew told those
who don't, it would have helped if I had posted my experience, it would have
helped more if the folks at Arion had posted their much earlier experience,or
even better put on their site as an information note so that it was easily
accessible.
Buzz, you do a good job with the newsletter, I don't think its your job to dig
out the material as well.
It does not require a rare set of circumstances to achieve high temperatures on
the glareshield. It requires canopy open for one to two minutes with the sun
maybe 30 degrees either side of the tail to melt the fabric on my plane. The
fabric is automotive trim fabric, not fireproof but not especially delicate either.
That's in spring at mid 30's latitude. To my mind, bits of my aeroplane
melting, producing smoke and possibly igniting is a non trivial occurrence
best avoided.
So what to do about it? Changing the geometry of the canopy is not something you
would want to do so its down to taking care how you park the thing and selecting
something suitable to cover the glareshield with. I think I'm going to
try some sheepskin.
I'll get some pics of my melted patches tomorrow.

Cheers, Selwyn

What I am trying to figure out is how you can fly around for 3 hrs and only
need 8 gallons of fuel.

I stand corrected by Tex and others in regards to materials used on the
glare shield.
By all means, if you use a material that will ignite on your glare shield,
you are indeed vulnerable to fire.
And that it could happen quickly.
I didn't think about the use of flammable materials in that spot.
By all means, it would behoove Lightning owners and builders to exercise
some caution and thought in their selection of materials and finishes.
Sufficient ablation is suggested in this location.

I love it when people put thier 2cent opions on topics on the list. I bet
they would be totally different if it was thier plane that was damaged.
P.S fiberglass covered with fabric will not only soften but will burn very
nicely and the flame will effect the canopy its self.

SN107 has flown today at 11am. This is an LS-1. All went well with no
problems noted. Normal adjustments to be as expected and some more flying
this afternoon.
