Images 1 and 2 show me match drilling the lower leading edge surface to the Landing Light frame. Note in Image 2 that as I move accross the frame I immediately put a cleco in the drilled hole (from the inside so it's easier to drill) to keep the frame in place. Image 3 shows that no matter how many holes you drill, you're not done until you deburr each hole.
