My air struts for the Cruiser doors got lost in the move to Florida. I know
that this was discussed before
but I must confess to my ignorance of how to dig up past posts. Whats a
good place to buy them and
what type and size should I get?

I order mine by phone from Guden. See here:

The type I use is the standard black ones like these:

For length you have to measure your own desired door opening and closing
situation. Some Cruiser builders favored the 35 PSI type and used two
per door.
Good luck,

As most of you know, my plane was damaged in a accident when taxiing in February.
Having dropped the wing, we found the rear left spar/support strut broken on
the wing side of the juction with the fuselage. Enough space there to implement
a good and proper fix with alu sideplates added into the (on both sides of
the plane) so no problem.
The bigger issue is that the main spar has a compression fracture at top aft corner
of the spar beam where it exits from the spar box on the left side. A photos
of this is attached (with vernier calipers set to about one inch). Luckily
it is on the top side.
Question for Rich (or anyone else who has the knowledge) Do you perhaps have access
to a drawing of spar construction or could you describe it in brief?
Today I visited two composite material workshops which specialize in sailplane
spar and wing construction and repair and have extended this knowhow to other
composite aircraft as well. The owner of one of these enterprises has been building
and repairing wings and spars since the seventies and it is evident that
the repair my wing spar is a nothing out of the ordinary for them. In all those
years they have never had a failure in a repaired spar and hey have the knowhow,
methods and tools required for the job down pat. He was kind enough to
'walk' me through the process and equipment they would use. Pricey it is, yeah
in the high four figures sterling.
So now I have a dilemma. I can walk away and buy another plane for (say) 25 grand.
Then I have a 2nd hand plane that I need to sort out from scratch. On the
other hand I could apply that same 25 grand to completely repair and refurbish
the current plane including zero-timed (SMOH) engine, new paint job and fixing
all the niggles that I want sorted out (like rudder pedals, stress on rudder
horn, location of main gear, electric flaps, etc.) Then I have an aircraft which
is effectively refurbished to my standards and which I also know inside-out
by the time the job is done. [Note: I have already decided that the time required
to get the job done is not a factor in my equation.]
So what you do in my shoes? (assuming that I buy back the salvage for a nominal
sum, having already confirmed that competitive interest is effectively non-existent).
I shall make up my own mind, dont worry just need different perspectives
if you care to share.
Regards,
Alfred

G'Day Again Alfred ...
Here is my 2bobs worth ..
A repaired Main spar aircraft will suffer a substantial asset value drop
..probably around the actual repair amount at least. So now there is two
costs ..the repair cost and the asset depreciation cost .... So i wouldn't
go the repair route ..
However ...if u could find a TR1 kit or unfinished project ... well that
would be whole different story .. Completion failures of Kit projects is
said to but way high ...so a suitable wing, wink/kit is almost certainly out
there ... probably be a world wide search ..
If a spare parts search came up with nothing .. i would put the insurance
payout in the pocket and walk away .. !!
Luv to hear from Rick about any wing kit availability ...!!??

I don't think 25 grand can buy you much of a plane. I would fix my own.

This is Jesse Wright
I will also give my 2 cents worth concerning how I would feel about fixing
a fractured spar. Thinking about what Rich has cautioned us about over and
over is, "Do not drill the carbon fiber in the spar or rail pieces. This
is also concerning even drilling the tips, outboard wing spar. This is
because the carbon fiber runs as complete fiber from one end to the other.
Any cutting of this fiber will let the fiber slip through and let a bending
moment occur along the fiber. It seems to me a bruise toward the center
would be much worse than at the wing tips. Remember, "Don't drill this
fiber, even on the wing tip for tie downs eyes.
I have hit turbulence that I have hit my head on the roof before I could
get it slowed down. It was so severe that it stung my neck. I would live
in freight to think what this might bring, I could never put all my weight
down. Ha.
If Rich might have a spar laying around, left over from his kits, you might
think about ripping of the skins and replacing the spar. This would
depend on how well you sanded and bonded the skins on. Maybe he might know
where skins and spars might be.
I'm sorry for your loss but I hope never to hear of a greater loss.

McMaster Carr has a good selection.- If you get a strut with too high a f
orce it will distort the door when closed.- I'd look for one about 18" lo
ng and about 30 pounds of force.- I'd buy one and mess with it and see if
the force and length workout.-
