Beginning of the landing lights installation. First thing is to mark the cut out with the template.



The I riveted the nutplates that will be used to secrew on the support plates I primed yesterday. The nutplates on the outboard rib got riveted with standard rivet, on the inner rib I used pop rivets they are barely visible on the picture.



Then the cutting. I used my pneumatix die grinder with a cutting wheel. To be on the safe side I cut quite far away from the line.



The first cut was too far from the line, I had to do another one nearer, then everything got sanded and deburred.
