Hi, new here, lurked for awhile but haven't posted until now...
I have a Fisher 404 that hasn't flown in about 10 years. The issue is the rib stitching, or lack thereof. As near as I can tell, this design (95 mph Vne) allowed glue to secure the fabric to the ribs in lieu of rib stitching. On my plane, I don't know whether glue was used (some of the fabric is stuck to the ribs but some is not), but the builder rib stitched it not with the usual waxed chord, but with what looks like ordinary sewing thread, most of which is broken. Anyway, the A&P who's doing the condition inspection and I are discussing the best way to deal with this, the safe answer being to strip the fabric (which is in good shape) and , My thought is to restitch the existing fabric, with new finishing tape over it, but the A&P's concern is that it isn't a documented "standard" repair technique so he's reluctant to sign it off. Thoughts?
