I started today with riveting the E-703 and E-704 outboard ribs together. I then riveted the E610PP and E611PP reinforcement plates and platenuts onto the spar. I then riveted the inboard E-709 rib onto the spar(flush heads forward). Next I revited the E703/E704 complex onto E702 spar.
Next, I revited WD-605-1-R control horn to the understucture.
