Fuel tank Z-brackets

Category: Fuel tanks — Steffen @ 23:45 — Hours: 2

We had guests again tonight, but I managed to get a little bit done anyway. First I matchdrilled the fuel tank stiffeners to the tank skins, then I started preparing the Z-shaped brackets that will attach the fuel tank aft walls (baffles) to the wing main spar.

First I marked the centerline on all the Z-bracket flanges.

Then I drilled the center holes according to the plans, then cleco’ed them to the spars and drilled the last holes.

Last I began drilling holes for the nutplates that will go on these, almost done…
