McCauley Propeller Systems, a division of Cessna Aircraft Company, part of the Textron Aviation segment of Textron Inc., announced today the FAA Certification of the McCauley Propeller Systems' Blackmac Carbon Series constant speed composite propeller.

The propeller's advanced composite materials and patented high-strength, low-weight continuous carbon loop blade retention system significantly reduces propeller assembly weight and improves product life.

“The low weight of the Blackmac Carbon Series propeller, offers the ability to improve payload without compromising strength or weight in other areas,” said Scott Howell, McCauley Business Leader. “McCauley has spearheaded innovation in the propeller industry for generations. Earnest McCauley was instrumental in designing and producing the first forged steel propeller in the 40's, and today his legacy lives on with the certification of the Blackmac Carbon Series propeller.” 

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 with no set maximum life and with an overhaul interval of 2,400 hours or 72 months. The Carbon Series retains McCauley's standard industry leading parts—including the single-piece oil-filled hub—and labor warranty of 3 years or first overhaul. Compared to other aluminum propellers, it has 25 percent fewer parts. No other certified propeller rated at 350 Hp, wood or composite, weighs less.

The newly certified propeller will be on display at the 2014 Association for Unmanned Vehicle Systems International (AUVSI) Expo on May 12-15 at the Orange County Convention Center in Orlando, Fla.
