Brief Description: Baggage Door # 3 - Custom Aft Rib
Final matched drilled #30 the holes in the new aft rib in common with the doubler plate. Deburred all holes and dimpled for AN426AD4-4 rivets. Back riveted the rivets. The rib is quite strong. The un-intended consequence is the rib is now ~ 1/4" too short to meet the bottom bracket.
I'll need to extend the rib a bit with another doubler to ensure the aft rib can be riveted to the bottom bracket.
