VH-FAY Cessna 208B Supervan 900 (MSN 208B0884) of CGG Airborne at Jandakot Airport – Mon 9 March 2015. This aircraft has recently been converted from a standard Grand Caravan to a Texas Turbine Conversions Supervan 900, where the previous Pratt & Whitney Canada PT6A-114A is replaced by a Honeywell TPE331-12JR engine, and the 3-bladed prop is replaced by a 4-bladed prop. This conversion delivers a 40% reduction in takeoff distance, improved rate of climb, 14 knots faster on the same fuel burn (or 14% less fuel at the same airspeed), 7000 hour time between overhauls (compared to 3600 hours with the original engine), and a lower hourly operating cost. The aircraft is converted for geophysical survey, and is normally equipped with a magnetometer tail ‘stinger’. It has had two extra sensors added to the cockpit ceiling. Photo © David Eyre
