More drilling to remove HS-702 front spars. To remove the spar I’m drilling out all the skin rivets at and aft of the front spar on one side only, the front spar and aft main rib skin rivets on the other side, and the front spar to main rib and end rib rivets. This allows the aft main rib to swing out of the way and the front spar to be removed from the inboard side.
I finished removal of the left front spar and only have the skin rivets on the top of the front spar and aft main rib left to remove the right front spar. The replacement front spars, angles, and doublers are due for delivery in three days.
