Duncan Aviation recently delivered its 10th Falcon 50 with the company’s Duncan Design shell kit. It features a two-inch increase in seated headroom, new LED (light-emitting diode) upwash/downwash cabin lighting and new emergency oxygen boxes, among other improvements.

According to the company, the cycle time for a typical Duncan Design Falcon 50 refurbishment is about 12 weeks for the complete refurbishment, including the shell kit, depending on the condition of the aircraft upon arrival and the requirement for any additional options.

The Duncan Design program was introduced in 2004, and similar upgrades are also available on the Challenger 601/604, Citation 560/650, Gulfstream II/III/IV, Hawker 800 and the Learjet 35.
