Today I drilled platenuts to the wing root skin. These are what the wing root fairings screw into. After drilling all holes were deburred and then dimpled or countersunk as required. Platenuts were riveted to the wing skins.
The front deck structure was disassembled. All holes and edges were deburred. Holes were dimpled as required. Vertical Power mounting brackets were drilled for platenuts, deburred and countersunk and platenuts riveted. Brackets alodined.
