Elevator ( 4 hrs )
Sect 9-17, Step 3: Completed rivets to Ribs & Shear Clips to LH and RH Rear Spars.
Sect 9-18, Step 1 & 2: Primed all 4 Skins inside surface along rivet lines and similarly scuffed zones (only). Removed tape from zones for bonding Foam Ribs and TE later (see pic below)
Then riveted Forward Hinge to Rear Spar & Top Left Skin.
Temporarily assembled Trim Tab hinge to confirm smooth operation. Looks and works great !
Step 3: Back Riveted Ribs to LH Top Skin.
Step 4- 5: Right Rear Spar riveted to Right Bottom Skin. Careful to mark locations not to be riveted at this time, too. Plan to back rivet Ribs to this Skin tomorrow....
