Layed up two parallel plates at aft inboard intersection of upper and lower copilot footwell tanks. These plates overlap (released). When cured a hole will be through drilled and a nutplate added to the inner plate. This will hold down the aft inboard side of upper tank as well as preventing any aft movement.
Cut tank floor for aft footwell upper tank from previously layed up 4 bid carbon. Added reinforcing bids to fwd footwell locking devices.
