The Federal Aviation Administration (FAA) has certified McCauley's Blackmac Carbon series of constant-speed composite propellers.
Manufactured from advanced composite materials, the Blackmac features a high-strength, low-weight continuous carbon loop blade retention system, which significantly reduces 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 40s, and today his legacy lives on with the certification of the Blackmac Carbon Series propeller.”
The scimitar propeller blades are optimized for balanced performance, and are made of seamless carbon fibre and fibreglass material featuing nickel leading edges for greater strength, durability and impact-resistance.
The Blackmac Carbon Series was certified with no maximum life and an overhaul interval of 2400 hours or 72 months. Compared to other aluminum propellers, it has 25 percent fewer parts.
