Does anyone know if there is a STC to replace the two bladed props on the 500A to three bladed Hartzell/McCauley props? Any info would be greatly appreciated. I have a set of Hartzell's available from a 55 Baron but I'm looking for some guidance on anyone else who has made the switch or knows where to find the STC. Hartzell doesnt have one. If there is any other options available that anyone knows of that could work that would be great also.
Thanks
