Before you start drilling, try a Craftsman precision Phillips
screwdriver. They have a sandblasted tip that really grips. Another
trick that I used was to drive an Allen wrench into the hole drilled
through the screw. I didn't have an easy out that was small enough and
this did the trick. I was really cursing Cessna by the end of that project.

I have found that if you start with a small drill and slowly increase
the size, you can drill out the center of the screw with minimal damage
to the threads in the hole. This is because the screw threads are harder
than the body of the screw and tend to guide the drill toward the
center. If you increment the drill size slowly, all that will be left is
the threads. You can pull them out with a needle nose if they don't
simply wrap around the last drill.
