The King Air 350 is modified by Raisbeck Engineering with Hartzell’s newest structural composite 106-inch diameter lightweight five-blade propellers.
SEATTLE — Raisbeck Engineering is unveiling a newly certified EPIC Performance Package for the in-service King Air C90GTx fleet of nearly 150 airplanes.
The improved performance comes from Raisbeck’s Swept Blade Turbofan Propellers, combined with Dual Aft Body Strakes, and takes advantage of the low-speed contribution of the factory installed winglets on that specific model, company officials explain.
Raisbeck Engineering’s latest development in swept-blade propeller technology, the new Composite Swept-Blade 5-way Propeller for the Beechcraft King Air 350 series, has begun FAA certification flight testing at Boeing Field in Seattle.
The Raisbeck/Hartzell team completed all ground and flight vibration and governor output pressure surveys Sept. 7. The program began company and FAA certification flight testing the following Monday, scheduled to be completed by the end of September.
SEATTLE — Raisbeck Engineering’s Swept Blade Turbofan Propellers are now being delivered after receiving FAA certification covering the entire King Air C90/E90 family.
Gross sales at Raisbeck Engineering continued to grow for the third straight year, following 2008’s industry-wide setback, company officials report.
