History
Between the Beech Baron and Queen Air in size, performance and general capabilities, the Duke was a pioneer in the pressurised high performance light business twin class.
Design features of the Duke include turbocharged Lycoming TIO541 engines driving three blade propellers and a 0.32 bars (4.6psi) cabin pressure differential.
The airframe was based loosely on the Baron's wing and undercarriage, plus a new fuselage employing bonded honeycomb construction.
