Unless your STC reads differently, there may be a slight error at about 11:25 in the video. AC 43.13-1B, Section 2-9, paragraph (a), states this: "...Where multiple attachments are in close proximity, such as on a wing rib, continuous reinforcing tape should be installed, extending at least 1 inch past the last attachment at each end..." I'll need to go get your STC manual to read it, as that would take precedence over AC 43.13-1B, but does it state that you only need to extend 1/2" past the last stitch. Not to be overly pedantic here or anything, but that could be a real pain in the butt if a person only extended 1/2" past the last stitch, and then it failed inspection because it wasn't a full inch. I'm not sure any inspector would catch that (my guess is yes), but back in A&P school in the 1980s, we had a couple of ex-military instructors who would absolutely bust you for it. So then you'd have to do a bunch of work to make that right.
@@dennisjansen9951, so, is there a gap in the hidden stitches? I'm recovering a Pitts wing and there are so many stitches that some of the ribs need 20 feet of string (hopefully... It's my first time doing this) and I've had to remove an entire row because I ran out with 3 stitches left. We are supposed to have a continuous string from beginning to end. Also, thank you for your reply and your video. I've already used some of your techniques and they helped out a lot.
RR830 no, no need for one continuous string for each rib. Easier to handle a shorter string, rather then 20 ft. Just tie off the string that is too short like in this movie, and start with a new string as you did before. Thanks for you reaction. It’s not me in the movie. I just shortened and categorized the Stewart Systems clips. Easier for me to find the info I need. But somehow it is found by a large amount of people 😂
What I don't see and wished for is the technique of the person assisting with the rib stitching who can pass the needle back hole through the rib and hit the ret
The rib sticking looks so complicated that it's the most difficult part of the whole redoing fabric on the whole aircraft.
Just like drywall, very cool

Excellent film footage and commentary.
Pro trick: you can watch movies at KaldroStream. I've been using them for watching all kinds of movies during the lockdown.
@Blaine Malachi yup, I have been watching on kaldrostream for since december myself :)
I always stiched my cubs at 2.5" in slipstream and 3.5" out of slipstream
Fascinating, great skill and knowledge. Thank you.
While rib stitching, if you cut yourself short , can you add string with a knot? And if so, what kind of knot? Is this safe and secure?
Well I think it’s possible, but it’s way easier to end your last string and begin with a new string.

I should clarify. We only need to have one continuous string for each rib, not the entire wing. 😉

@@dennisjansen9951, well, the video was fabulous and thank you so much for your fast replies and great editing. 😊
how much you charge to recover a set of Cessna 140 wings?????
Ralph Witt, please check at Stewart systems.

return hole where the knot goes every time. That is a lot harder than it looks. It also would help to show how to lay out the back side of the wing.
