Brief Description:  Troubleshoot Wing Rib Errors

Troubleshoot Wing Rib Errors
- Ribs 15-108 too high vs. tapered spar
- spar taper was set-up correctly (but is wrong)
- notches for stringer-1 were problematic and tipped me off to issue

Solution:
- when wing geometry was corrected to extend LE & TE tapers to fuselage centerline (vs. going straight across fuselage from WS12.25 to opposite)
- Rib 12.25 LENGTH was extended automatically to match the new planform
- HOWEVER the height of the NACA 0016 airfoil at WS 12.25 was NOT recalculated for the new chord length
- THUS Rib 12.25 is TOO LOW
- Spar taper starts at WS12.25 & is TOO LOW as well
- when Rib 12.25 is corrected, spar taper starting point will be raised and taper will be correct
