McCauley Shows BlackMac Carbon Series at Sun ’n’ Fun

April 2, 2014, 10:30 AM

Cessna Aircraft subsidiary McCauley Propeller Systems is displaying its new Blackmac Carbon Series constant-speed propeller at this year’s Sun ’n’ Fun fly-in event in Lakeland, Fla. The world’s largest full-line propeller manufacturer expects to receive FAA certification in the first half of the year for the clean-sheet scalable design that features composite materials and uses a patented high-strength, low-weight continuous carbon loop blade retention system to reduce weight and improve product life.

“This new propeller is the lightest in its class,” said Scott Howell, McCauley business leader. “No other certified propeller rated at 350 hp, wood or composite, weighs less.”

The new design retains McCauley’s single-piece oil-filled hub and has 25 percent fewer parts than a comparable aluminum propeller, Howell added. The scimitar-shaped blades constructed from seamless carbon fiber and fiberglass feature electro-formed nickel leading edges for durability and impact resistance. Indeed, the new propellers are certified for unlimited life and an overhaul interval of 2,400 hours or 72 months and include the company’s parts and labor warranty of three years or the first overhaul.
