2.0 hrs
Trial fit of all screws and bolts for left tank attach.
Fit tank and install half of screws and bolts.
Final check of left wing twist, less than a 16th.
Start clecoing top inboard skin and doubler to left wing for final riveting.
Decided to stop before installing too many rivets. I want to double check the inboard/outboard overlap. And I need to prime them before installation.
