Trimmed the ER tank access doors. Fabricated, fit and drilled on the door attachment flange to each wingtip. I orded some Skybolt fasteners yesterday that I'll use to hold down the doors. Instead of a hinge, I'll use an aluminum tab on the inboard end of the door. That will make the door fully removable but will also avoid the ugly piano hinge. I considered a hidden hinge but there really isn't sufficient room due to the close location of the ER tank.
Verified the opening minus the aluminum attachment flange
