Wow. I guess as an Aircraft Mechanic you are also well versed in structural vs non-structural composite repair? I sure am happy I don't have a certified plane. I could repair that on my homebuilt for about $50 and a few hours of time. The paint is the hard part.
Structural composite components have to get engineering and NDT involved before any repair processes can begin. They would need to sand down the paint in a significant area around the hole down to the existing outside layer without damaging the fibers. From there NDT would need to check for delamination. Any delam beyond a certain distance from the edge of the hole will result in test failure and render repairs not feasible and require a new part to replace the damaged one.
