Momentum builds for McCauley Propeller’s King Air B300 aftermarket solution

Wichita, Kan. (July 26, 2022) – McCauley Propeller Systems today announced at EAA AirVenture 2022 that testing is rapidly progressing on its new 105-inch diameter propeller, featuring four aluminum swept blades, for the Beechcraft King Air B300 series.

We are excited about the progress made and overall testing performance. Not only will customers receive a propeller with a modern swept appearance, but will also benefit from reduced noise in the cabin and cockpit. Customers will also recognize a propeller weight savings of more than 50 pounds per aircraft, thereby increasing overall useful load for the operator. The result of the work we are doing now with our test program will help us move through certification, ultimately bringing a high-performance King Air B300 series propeller to the market. John Dandurand, vice president and general manager, McCauley Propeller Systems

Owners and operators will also benefit from:

  • Extended Time Between Overhaul (TBO) of 5,000 hours or 72 months
  • Textron Aviation’s 4,000 hours or 36-month limited propeller warranty
  • Installment of the McCauley propeller does not require changes to existing aircraft operating procedures or additional aircraft modifications

Certification of the propeller is expected in 2022. Advance orders are now being accepted through McCauley Propeller Systems or Authorized McCauley Service Facilities.
