I will be using a Garmin pitot probe with AoA so I don’t need the stock stall warning system.
This requires me to fill the pilot holes on the leading edge of both wings (where the stock sensor would be installed). I used flush rivets to fill the holes. I used NAS 1097 AD 3-3 rivets (aka “oops rivets”) to minimize the countersink depth that was needed.
I was able to rivet these in carefully with reasonable success (one is very close to the rib).
I then filed the rivet heads to match the profile of the leading edge.
The rivets worked out well and will disappear after paint.
I then proceeded to reinstall the tanks. This is a bit of a tedious process and hopefully these are now installed for the last time.
