RFDS Upgrading PC-12s with Five-blade Hartzell Props
The Royal Flying Doctor Service is planning to install Hartzell composite five-bladed propellers on all 16 of its PC-12s.

Royal Flying Doctor Service (RFDS) in Western Australia is upgrading its fleet of Pilatus PC-12 turboprop singles with Hartzell 105-inch-diameter, five-blade composite propellers. The new propellers will replace the existing Hartzell four-blade aluminum propellers on the utility aircraft that the RFDS uses for medical emergencies and patient transfers. Last year the RFDS fleet transported 9,012 patients over 8 million kilometers (4.97 million miles) across Western Australia, reaching some of its most remote corners.
