My Mom who runs a aircraft recovering shop in Santa Paula Ca(Rowena's Flying fabric) was wondering if anyone has rib stitched there Rf4d?
She and my Dad Recovered a Rf4d wing A few years back and were concerned of the lack of rib stitching.
Any Ideas?

They were certainly not laced in the factory. The wide cap strips and strong adhesive must provide sufficient strength. I have never seen a Fournier with laced wings, nor have I ever heard of one with fabric peeling from the ribs.
I did try to remove some fabric from a rib recently though and it was very difficult to get off!

Hi again Sam,
No, Fourniers do not have their fabric stitched in place.
Many other types of airplane also do not use rib stitching.
As Steve says, there is enough glued area to hold the fabric securely in place with 6 or more g pulling on it at Vne and above. I know this for certain!
Yours, Bob
Incidentally, Santa Paula's my favorite American airport. I used to go there frequently on Los Angeles stopovers when I flew 747s for British Airways. I first flew a Pitts there, I bought my little Bellanca Champ after flying one there, and I still have a Screaming Eagle key fob on my Maule's keys.
Yours, Bob

Fourniers have solid plywood ribs (without any holes), so the stitching is quite impossible to do.

If we were to stitch we would do it around the ribs.
but i have come to agree that i think it not ganna rip off if we ever buy one.
Thanks for your inputs!

Technically, rib stitching refers to attaching the fabric to the structure by stitching directly to the structure. eg, on a Blanik sailplane, the aileron rib cap strip is wrapped in cotton, and the cover is stitched to that. One stitch on the top, one on the bottom.
Rib lacing refers to a big stitch that goes all the way through the wing and is more commonly used on US light aircraft.
So you cannot rib stitch a Fournier, but you could rib lace one if you really wanted to. 
This from the Polyfiber procedure manual, which coincidentally I happened to be reading last night.

You are welcome! - We learn something every day, and I learned that yesterday!
If you don't mind me asking, are you related in any way to the well known movie pilot Sammy Mason, famous for his Bucker Jungmann flying and for teaching many movie stars to fly?

Wow. - Then I am more pleased to know you than ever 
I have had the pleasure of flying ou grandfather's Bucker Jungmann. It is now owned by Steve Hawley, of South Carolina. It doesn't look much like it did in the 1960s, but it is still a beauty.
Come on over to my website at www.bucker.info and I think there may be some pictures of it there. It's the yellow aircraft in this picture: http://www.bucker.info/index.php?option=com_gallery2&Itemid=49&g2_itemId=5286 (but you may need to register to see it)
