Raisbeck Engineering has received STC approval from the National Civil Aviation Agency of Brazil for its composite five-blade swept propeller for the King Air 350 series. The propeller has also received certification from the FAA and Australia, with Transport Canada and EASA approval expected in the near future.

“We are thrilled our Brazilian customers are now able to benefit from the advantages the composite five-blade swept propellers bring to the King Air 350,” said Bill Lally, vice president of customer support. “This new STC approval broadens our ability to offer the propeller to customers across the globe.”

The propeller was developed in collaboration with Hartzell Propeller and is designed to improve King Air 350 comfort, efficiency, and performance. It measures 106 inches in diameter and reduces weight while contributing to short-field and climb performance. Raisbeck’s blade design sweeps the leading and trailing edges, increasing the propeller diameter, generating more thrust without increasing noise.

“The five-blade composite is an exceptionally quiet and high-performance propeller,” said Lynn Thomas, vice president of sales and marketing at Raisbeck.

The composite material offers weight savings when compared to other materials and provides unlimited blade life and the ability to maintain a more optimum airfoil shape. Raisbeck’s tailored airfoils also extend fully into the spinner, allowing for increased propeller efficiency and airflow into the engine.

Raisbeck also announced the appointment of Mayo Aviation to its global network of authorized dealers. Mayo Aviation provides aircraft maintenance, management, and charter operations. The company offers avionics installations, pre-buy inspections, and airframe structural repair.

Raisbeck Engineering is an Acorn Growth and Defense company headquartered in Seattle, Washington. The company provides aircraft modifications for business and commercial aircraft. Raisbeck’s acquisition of Butterfield Industries adds products such as fuel pan assemblies, replacement floor panels, oil/air separators, and oil residue collection systems.

Paperwork for propellers for the King Air 300 series has been submitted to the FAA, and Raisbeck expects approval in May. “This will be an exciting year for us. We are really focused on the leading edge of creative thinking,” said Thomas.
