Brief Description: Used Borescope to check Alignment of Rib
After talking to a friend at work who used to teach a course on building RV Empenages. I decided to use my newly aquired borescope to check on what he called the hidden Rib. I really could not get a good look at this rib with the mirror. It is the 2nd rib outboard on each half of the horizontal. I was concerned that maybe the rib was not lined up properly before I match drilled the assembly. But everything looked good on both L/H and R/H side.
