This new STC provides increased performance (5 percent improved take-off & climb, 3-5 kts cruise with 1800 rpm), maximum durability and reliability. Suitable for all weather operation.

The propeller installation:

  • Provides best vibration damping characteristics for almost vibration free propeller operation
  • Has bonded on stainless steel leading edges for best erosion protection of the blades
  • Reduces the weight by approx. 7 lbs compared with the original metal propeller
  • Provides a cooler ITT on ground with condition lever at low and high idle position
  • Has no propeller speed restrictions on ground while operating in low idle
  • Gives more ground clearance for less FODs
  • Provides significant cabin noise and vibration reduction
  • All models comply with the strict German noise regulations 2010– "Landeplatz Lärmschutz Verordnung"
