AOG Air Support of Kelowna, B.C., Canada is undertaking a program to convert Cessna 208 Caravans from their original 675-shp P&WC PT6 to the 751-shp Walter M601E turning a five-blade Avia propeller. The company, which expects to complete the program in about 12 months, said the Czech engine and propeller will improve the turboprop single’s performance on both wheels and floats. Conversions are expected to cost $400,000.
If you’re looking for evidence the single-engine turboprop is an aircraft whose time has come, Comp Air Aviation (Booth No. 8842) believes its Comp Air 12 is exhibit A.

Of all the sub-segments of the general aviation market, the turboprop field is the only one not experiencing a marked increase of new development. At airshow after airshow, very light jets, personal single-engine jets, more powerful piston singles and light sport airplanes have garnered the greatest amount of attention.
Honeywell announced recently that it had won approval for its TPE331-12JR turboprop to be installed on the Cessna Caravan. The certification was completed in connection with Aero Twin in Anchorage, Alaska, which plans to offer complete retrofit kits, installation and service.
Australia’s Civil Aviation Authority (CASA) has grounded several Cessna 441 Conquest II turboprops, citing the potential for in-flight structural failures on aircraft that have surpassed 22,500 hours. CASA stated that the defect, located near the rear pressure dome, could cause the tail to separate during flight.
