Horiz Stab  (4 hrs )

Sect 8-9 Step 1 & 2:  Inboard Inspar Ribs riveted to Stringer and Web.   Finally, beginning to put it all together starting with this sub-assembly.

Sect 8-10:  Finished Steps 1 to 3.   Riveted Front Spar to Ribs.  (note:  two center Inspar Ribs are not yet riveted to Spar pending Nose Rib assembly at same time...next section).

I tried to use Main Squeezer for all the ribs, but several configs didn't allow proper reach &/or interfered with the rib's flanges.   I messed up one rivet, so after removing bad rivet, I switched to rivet gun/tungsten bucking bar...and it was easier.
