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.
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
@@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 😂
4:57 The low pressure on top of the wing is likely to flatten that out; any images of the wing in flight? 6:25 Why change to metric? Or why not start with metric on top? Either does the job, it just seems to introduce the chance of a mistake to change. 21:38 That progression is certain to make sense to those who have done it may times. If I were to do this, I'd have to have the vid running at every knot!
