Testing is rapidly progressing on McCauley Propeller Systems' new 105 inch diameter propeller, featuring four aluminium swept blades, for the Beechcraft King Air B300 series.

“We are excited about the progress made and overall testing performance,” says vice president and general manager John Dandurand. “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 recognise a propeller weight saving 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 programme will help us move through certification, ultimately bringing a high-performance King Air B300 series propeller to the market.”

Owners and operators will also benefit from extended time between overhaul (TBO) of 5,000 hours or 72 months and Textron Aviation's 4,000 hours or 36 month limited propeller warranty. Installing the 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 authorised McCauley service facilities.
