I too have had the prop expeience. Mine was through the front of an A200 twin with carbon 21x27 fiber prop on alky. Damage was so severe it required a helicopter flight, major surgery and months of rehab. No knucle, destroyed knucle, stretched tendens fractured fingers, some skin grafs and all is 50% normal.

Here is what I learned. You better have a safe routine and follow it. Dont develope a set of "risky" routines. Make sure they are safe with built in safe procedures. Then follow them every time. Im not giving a free pass to complacency at all, but many will get that way unfortunately, and the safe routine will act as a fairly good buffer.

You can bet I double check every prop/hand clearance prior to removing any ignitor.
