June 28‚ 2018 – Seattle, Wash. – Raisbeck Engineering, Inc., a leading provider of performance enhancement systems for business and commercial aircraft, today announced it has received Supplemental Type Certificate (STC) approvals from the Federal Aviation Administration (FAA) for the company's five-blade composite swept propeller and four-blade aluminum swept propeller for the Beechcraft King Air 300/300LW aircraft.
“We are pleased to offer King Air 300/300LW operators the opportunity to upgrade their aircraft with added performance, efficiency and a quieter cabin with either one of these propeller systems,” said Lynn Thomas, acting President of Raisbeck Engineering. “These STCs are the result of many long hours from our engineers and their support team.”
The advanced design of the five-blade carbon composite swept propeller blades allows for unlimited blade life and reduced maintenance costs while providing the strength and durability expected from modern composites. As an alternative, Raisbeck is bringing its four-blade aluminum swept propeller, which has already been approved for the King Air 90, King Air 200 series and King Air B300 series, to the King Air 300/300LW .
