As Pilatus was celebrating the worldwide fleet of more than 500 Pratt & Whitney PT6A-67B-powered PC-12s surpassing one million flight hours, the engine manufacturer was working with the fuel control unit (FCU) supplier to obtain approval for an improved pneumatic system. P&WC expects to have an upgrade plan in place before the end of this month.

FlightSafety International is scheduled to deliver the first simulator for the Piaggio Avanti to its West Palm Beach, Fla. facility next September. FlightSafety said this simulator will represent the new Avanti II, the planned successor to the basic model featuring more powerful PT6 engines, Collins Pro Line 21 avionics and an increased mtow.
The NTSB wants the FAA to require Pratt & Whitney Canada PT6A-60 starter-generators to be electrically isolated from the rest of the engine, a modification that is already in the works.
A leak in the fuel control unit pneumatic system caused the P&WC PT6 to fail in a Pilatus PC-12 on December 14, according to Pilatus (see AIN, January, page 46). The pilot was able to deadstick the turboprop single to a safe landing on a street in South Bend, Ind. Pilatus re-issued a service letter to remind PC-12 operators that there is a manual override procedure that enables full power to be restored if the fuel control unit fails.
On display at Aero India 2005 earlier this year (see facing page) was the Saras, a low-wing aircraft with an mtow of 13,450 pounds and powered by two 850-shp Pratt & Whitney Canada PT6A-66 turboprops driving Hartzell five-blade pusher propellers, being developed by India’s National
Honeywell has delivered the first production TPE331-12JR-701S turboprop powerplant to Aero Twin in Anchorage, Alaska, for its “850 Caravan” re-engine modification program. The 850-shp engine, certified last September, will replace the original 675-shp P&WC PT6 on the big Cessna single. Aero Twin expects to receive an STC for the conversion this spring.
Kansas City Aviation Center’s Chesterfield, Mo. facility has been given an FAA Part 145 designation. Midwest Aviation Center (MWAC) was established last August by KCAC on Spirit of St. Louis Airport. The facility is approved for all small aircraft, the Pilatus PC-12 and Piper Malibu/Meridian series, King Air 200 and Citation 500 series. It is also approved to service most Continental and Lycoming engines as well as the TPE331, PT6 and JT15.
Timken has acquired Turbo Engines, of Tucson, Ariz., as it continues to expand its presence in the aerospace aftermarket.
EADS Socata today unveiled the TBM 850, a slightly faster, re-engined version of its TBM 700 turboprop single. The new model will have a maximum cruise speed of 320 knots, 20 knots faster than its predecessor thanks to a higher-power 1,825-shp Pratt & Whitney Canada PT6A-66D engine (derated to 850 shp). The TBM 700 is powered by a 1,583-shp PT6A-64 derated to 700 shp.
Spokane, Wash.-based Rocket Engineering is developing the Turbine P/Baron in parallel with the Royal Turbine Duke program. The Baron conversion, which fits two PT6A-21 turboprops and Hartzell four-blade full-feathering-reversing metal props to the light twin, costs about $700,000 (airframe additional). The company plans to have an STC in about 12 to 18 months.
