McCauley Propeller Systems, a division of Cessna Aircraft Company, part of the Textron Aviation segment of Textron Inc., is showcasing the Blackmac Carbon Series constant speed composite propeller at this year's Sun 'n Fun international fly-in and expo.

The clean sheet scalable design is expected to receive FAA certification in the first half of 2014. The advanced composite materials and patented high-strength, low-weight continuous carbon loop blade retention system, significantly reduces weight and improves product life.

“The Blackmac Carbon is the next step in propeller evolution,” said Scott Howell, McCauley business leader. “This new propeller is the lightest in its class. No other certified propeller rated at 350 Hp, wood or composite, weighs less. The Blackmac Carbon series retains McCauley's widely popular and proven single-piece oil-filled hub and has 25 percent fewer parts than comparable aluminum propellers.”

The scimitar propeller blades, optimized for balanced performance, are made of seamless carbon fiber and fiberglass material and feature electro-formed nickel leading edges providing a stronger, more durable and impact-resistant product.

The Blackmac Carbon Series is certified for unlimited life and an overhaul interval of 2,400 hours or 72 months and retains McCauley's standard industry leading parts and labor warranty of 3 years or first overhaul.

McCauley is the world's largest full-line propeller manufacturer and has been designing and manufacturing high-quality propellers and systems for the commercial, general aviation and defense industry for more than 75 years.
