Hawker Beechcraft GCS also announced here at EBACE its development of an aftermarket retrofit kit for Hawker winglets on the Hawker 750. Emmanuel Muntmark with Monsson S.A. of Romania, is the launch customer for the modification. Bucharest-based Alfa Air flies Muntmark’s Hawker 750 for charter.
“The winglet gives the Hawker 750 an additional 100 nautical miles in range and a five- percent improvement in time to climb,” said Brian Howell, Hawker Beechcraft, vice president, strategic aftermarket integration, GCS. By effectively increasing the wing aspect ratio, it will also improve stability at altitude, reduce life-induced drag and provide more responsive handling in slow flight.
The modification is expected to be certified in June. “Because this is the same winglet as on 800 and factory-installed on the 850 and 900XP, virtually all of the hardware and procedures have been developed, documented and approved,” Howell explained. The cost of the winglets is $295,000 and installation downtime is expected to be 10 days. “On 800XPs, we can now do the winglets in less than 10 days,” Howell claimed.
