-Un cleco'd the right left side fwd skin F820 -Re cleco'd the substructure underneath -Clamped the F883 fuel valve bracket to the aux longeron and mid cabin brace on the left side. Marked the holes on the aux longeron and drilled to #30 and then #19. The position I placed the holes were fine for the aux longeron but not good for the fuel valve bracket (no edge distance) so I'll be ordering a new one of those. Actually I'm going to use an Andair valve and it seems like it uses a different bracket anyway. I need to research that. -Unbolted and uncleco'd everthing that wasnt riveted together in the fwd fuselage sub structure.
