Owners and operators of Hawker Beechcraft King Airs enjoy the solid reliable performance offered by the venerable turboprops, but there is one King Air characteristic that probably isn’t appreciated, their propensity to turn nacelles brown with exhaust stains. Long-time EBACE exhibitor Frakes Aviation (Stand 434) has a solution: aerodynamically optimized retrofit exhaust stacks that route turbine tinges away, leaving nacelles clean and shiny.
Frakes Aviation has been manufacturing King Air exhaust stacks for more than 40 years, and its products are available for most King Air models, from the 100 through 300 series. Basically, any King Air powered by a Pratt & Whitney Canada PT6-20A engine or higher can use Frakes exhaust stacks, according to Joe Frakes, who founded the company with his father. The exhaust stacks are manufactured under FAA-approved parts manufacturer approval regulations and installed under an FAA supplemental type certificate, and they are also EASA-approved.
