Schweizer 330 / 333

schweit-333t
330T


The Schweizer turbine 330 is powered by an Allison 225-C10A engine. The new 350 shp Allison engine has been derated to 200 shp in the 330, which the company claims will provide a full 200 shp under standard day conditions up to 18,000 feet or to 16,000 feet on a 95oF day.

The piston-powered 300 and the turbine-powered 330 have virtually identical dynamic components - main and tail rotor blades, transmissions and drive shafts - with the exception of the powerplants.

In training configuration the 330 features three abreast seating, with the middle seat raised and slightly aft to give the instructor an overview. Another variant, for the civil utility market, has four seats in two-by-two configuration.

In September 2000 Schweizer Aircraft received type certification for the 333. This upgraded version of the 330SP features a new rotor system composed of cambered airfoil blades combined with an increase in maximum and continuous takeoff power. This gives 290 lbs more useful load and a cruise 20 kts higher than the 330SP. The 330SP may be upgraded to the 333.
