Silver Sky Aviation in Wasilla, Alaska The Phoenix-based Blackhawk Group has acquired Wasilla, Alaska turboprop maintenance provider Silver Sky Aviation. Alaska has seen significant growth in turboprop operations due to the combination of a turbine-powered aircraft’s range, speed, and payload with the reliability required to operate in harsh, cold-weather environments. As one of the few facilities in Alaska capable of supporting this demand, Silver Sky’s Wasilla center has earned a strong reputation by providing maintenance and performance upgrade capabilities for more than a decade. With the acquisition, Silver Sky joins the Blackhawk Performance Centers national network of Blackhawk aircraft modernization facilities focused on Beechcraft King Air, Cessna Citation, and others.
