How is this firewall insulation inside the cockpit on a PA-18 fixed? There are some screws and cables going through the firewall and the insulation. Is it glued additionally, if yes how? What is the work involved to have it exchanged?

Nothing to it...

Just pull the prop, cowling, engine, engine mount, firewall/cowl, (careful of the windscreen & inst. panel), and then tear oiut the old one, glue in the newie, poke holes, install grommets, install all the above.

If you have a midget helper you MIGHT get away with just cutting out the old one, gluing in the new one (with several slits to get around the control cables, & etc.)

Nimpo Cub,
that sounds frightening. Never expected to pull all things out in front of the insulation!
Shouldn´t it be possible to change it from the inside?
What glue?
BTW what is a midget helper?

Well, that's how they're put together.

If you can find someone small enough or flexible enough to get in under the panel, cut out the existing insulation & glue in another piece. (Well three pieces)
Contact cement should work well.
Make sure it's important enough before you start. What would a new piece gain you?

The old one is broken and temporary repaired with tape. Doesn´t look so nice to me.

Maybe just glue another one over your ugly one.
Ask your AME if you're allowed to do that if you're cert!!

Anything else ugly that I can help you with?

I'm gonna make a sign for my shop: Masectomys 5c.
(Yeah I am!)
