James, Chris,

This repair has been performed more than once. There is an aircraft
flying in NZ ZK-ZOO, which had this repair carried out.

Presumably Chris had the canard removed at the time of repair. The NZ
repair was carried out with the canard in situ leaving all the top
laminations and fuselage attachments intact. (of course, this is a
good time to cure the leaks into the center section)

It has flown many hours since.

Regards

John

James, I know you won't be doing the repair, but maybe someone

will. I

carried out a repair on the damaged canard I used in my project. It

was

approved by the PFA in UK. The Q2 had been cart-wheeled and

subsequently

avgas had got into the centre of the canard. So it was delaminated

at the

centre underside and about 15" out from the fuselage on each side.

I

stripped away the original laminations underneath the centre and on

top of

the canard on each side. I dug out all the damaged foam and

replaced with

new foam and micro.

After re-profiling, I did a normal type of glass repair at 1:64 (if

I

remember right) slope through the laminations. I did a

thorough "tap test"

of the whole canard to assess the remainder, but found no further
delamination or hollow areas. As I had the canard off, I then put

two more

layers of Uni top and bottom full span and over the wheel pants as

they had

also been smashed off and replaced.

This is not yet proven in practice, but it should be at least as

strong as

the original. I would think you (or whover) could work from the

underside of

the canard and so not even need to remove it, just the central

fuselage

covering behind the engine bulkhead if there is one. I didn't

replace this

so I can now inspect the underside of the canard in the centre

because heavy

landings can cause that to spring away from the foam due to the

tension when

the wing flexes. I made a gentle curve when I rebuilt the canard

centre, to

avoid the sharp angle.

Anyway, my 2 cents - opinion only.

With great remorse I must say that I have decided to part with

N145EX.

It will be sold to the highest bidder by January 5th, 2006.

The terms are as is, where is, cashiers check by January 6th in

full

payment. I will help you load the airplane onto your trailer.

The missing foam in the center section of the canard is the main

reason.

I can not bring myself to cut into the canard and replace the

foam. I

have been experimenting with injected foam, and this is still a
possibility. Another possibility is to cut a slot in the top

rear of the

canard center section and insert shear webs in place of the

foam. I would

like to know what the list thinks of this repair.

The strong points of this airplane are:
Frank Follmer full height rudder.
My VG design.
Wheel alinement.

Please see:

http://postma.com/N145EX/N145EX.html

I am losing my hangar space and business interests are keeping me

busy. I

may replace this airplane at some future time and will monitor

the list.

The airplane has some other issues firewall forward. Please

email me

and/or preferably call my cell.

The airplane has 110 hours now and has all the logs and required
documents.
