Seagull Aviation Premier Conversions has received supplemental type certification (STC) for installation of the Walter M601E-11A turboprop and Avia V5105 bladed propeller on 100-series Beechcraft King Airs. "The STC provides greater take-off performance, increased climb performance, reductions in exterior and interior noise levels, and greatly reduced engine maintenance costs," says the Clintonville, Wisconsin-based company.
