Right Fuel Tank Prep

April 5th, 6th, 7th, 2019, 15h

After getting the new z bars for the right wing tank, I went ahead with preparing this tank to catchup to the left one:

  • Drilled the z bars middle holes.
  • Checked the fitting of the fuel skin with the drilled z bar and the baffle,  I had to make some very small modifications.  By the end the filling looked good.
  • Drilled the rest of the lower holes in the 6 z bars
  • Attached plate-nuts to the z bars: drilling holes for rivets, deburring, counter sinking and riveting.
  • Attached the z bars, and checked the fitting again, it looked good.
