Cutting a hole for the pitot mast.Timer icon2h

September 15, 2025

Today I made a hole in the skin for the pitot mast.

Nothing too special, just followed the instructions for the pitot mast. My holes happened to be slightly offset one relative to the other, so I had to upsize them for the NAS1241AD3 rivet. Or I might upsize it all the way up to the AN426AD4 rivet (but pitot mast is barely thick enough for the size -4 countersink). Also, I added two extra holes compared to the instructions.
