I have early SN RV-12 120058 now with 522TT. Airplane is flown off of rough grass runway and most often in pretty good summer convection. I have hit my head twice on the canopy with shoulder straps sinched tightly.
I check for loose rivets at Annual Condition Inspection and also when cleaning bottom of plane. No loose rivets at present so I'm delaying the SB.
