New TBM 900 Features Improved Performance, Comfort

Daher-Socata unveiled its latest upgrade for the TBM series yesterday, the TBM 900. Retaining the same Pratt & Whitney Canada PT6A-66D engine rated at 850 shaft horsepower, the new model has improved performance based on aerodynamic optimization of the airframe and the engine air intake configuration. It also comes with a new five-blade composite propeller and a redesigned spinner.

Daher-Socata lists cruise speed at 330 knot at 28,000 feet, and improved time to climb of 18 minutes, 45 seconds to 31,000 feet under ISA conditions. Range (at reduced long-range cruise speed) improves to 1,720 nautical miles with five adult occupants, burning 37 gallons per hour. The redesign included 160,000 research hours and 200 hours of flight testing over three years, according to Daher-Socata.

Thanks to computational fluid dynamics analysis, engineers added winglets and redesigned the vertical tailfin strake and tailcone. The cowlings are carbon fiber and accommodate newly designed exhaust stacks. Inside, the panel and control pedestal have been redesigned and an ergonomically designed control yoke added.

Electrical power has been upgraded with a new 300-amp starter generator and a 100-amp standby alternator. Improved insulation lowers cabin noise, and redesigned seats add passenger and pilot comfort.

Nicolas Chabbert, senior vice president of Daher-Socata's airplane business unit said, "The TBM 900 provides a new competitive edge by delivering even more on the right combination of speed, performance, efficiency and fuel consumption."

The TBM 900 is certified and available for immediate delivery.
