05/29/2018 Horizontal Stabilizer – Match Drilled Rear Spars (1.5 Hours)
Today I match drilled the holes to size #30 on the rear spars and reinforcement bars.
After that I drilled a few size #21 holes for the HS-708 rib.
Then I match drilled HS-412PP and HS-413PP elevator hinge brackets to the rear spars.
