Raisbeck Engineering has received FAA certification of its 4-Blade Swept Propellers for the King Air 350 family.
The first deliveries are going to Raisbeck dealer Stevens Aviation in Dayton, Ohio, for an Indianapolis-based 350. The second is headed to Elliott Aviation in Des Moines, Iowa, also for a 350. Both aircrafts’ OEM propellers were up for overhaul.
The FAA certification follows a four-year development program, including 2½ years of flight testing of five different designs, including three five-blade versions.
Raisbeck’s engineers are now developing a companion EPIC Performance Package for the 350, which includes a target increase in Maximum Power Cruise Speed of over 10 knots, according to company officials.
