Cessna 208B Caravan, Globe, Ariz., July 22, 2005–The NTSB determined that the probable cause of the crash of Caravan N717BT was the fatigue failure of the compressor turbine stator vane, the liberation of vane material into the compressor turbine (damaging the turbine blades downstream) and the total loss of engine power.
Pratt & Whitney Canada PT6
Eagle Copters of Calgary, Alberta, has delivered its first three single-engine Bell 212 conversions. The “Eagle Single” features a single Honeywell T53-17A or B turboshaft engine in place of the 212’s Pratt & Whitney Canada PT6T-3B Twinpac.
The AgustaWestland AW119 Ke received EASA certification at the Paris Air Show last month. The helicopter, a derivative of the A119, was announced in late February at this year’s Heli-Expo in Orlando. The Ke (it stands for Koala enhanced) is powered by a single 1,000-shp P&WC PT6B-27A and has a higher mtow than the standard A119. U.S. certification is expected this fall, the company said.
Pratt & Whitney Canada (P&WC) continues to consider a possible new turboprop design that could provide a sufficient advance on the PT6, which through its myriad variants offers 700 to 2,000 shp. However, for the moment at least, the manufacturer sees no immediate prospect of moving on from the ubiquitous powerplant to a new-generation engine in the same power range.
Russian engine designer Klimov has revealed its first all-new helicopter turboshaft since the end of the Soviet era and said the powerplant will be aimed partly at re-engining helicopters powered by the ubiquitous Pratt & Whitney Canada PT6.
Some two months after announcing the relaunch of 19-seat Twin Otter production, Canada’s Viking Aerospace has begun cutting metal on the first unit at its final assembly plant in Calgary. Scheduled for delivery in the first quarter of 2009 to Zurich’s Zimex Aviation, the first Twin Otter 400 will look virtually identical to the operator’s “legacy” Twin Otter 300s.
Having passed responsibility for an engine for the planned Bombardier C Series 110- to 149-seat jetliner to its U.S. parent, Pratt & Whitney Canada (P&WC) says time devoted to the exercise has not been wasted. Rather, it is contributing to work on a 10,000- to 14,000-pound-thrust design–dubbed X10–aimed at a future generation of large business and corporate jets.
Hawker Beechcraft hopes to continue to stave off competition from VLJs with two new upgrades–announced last month at EBACE–to the stalwart King Air turboprop line. The upgraded King Air B200, which the company is calling the B200GT, gets more powerful PT6A-52 engines, while the C90GTi will be equipped with Rockwell Collins Pro Line 21 avionics as standard.

Piaggio Aero Industries’ speedy Avanti II, long acknowledged as the fastest turboprop aircraft in the world, is now even faster.
At EBACE, Piaggio announced that the European Aviation Safety Agency (EASA) has granted approval for installation of the Pratt & Whitney Canada PT6-66B in the Avanti II, giving the twin-engine pusher a maximum cruise speed of 402 knots (Mach 0.70).
