Testing and certification on the
Beechcraft King Air 90x composite winglet modification has been
completed, Hawker Beechcraft Services (HBS) said Monday. Winglets
for King Air C90 and E90 models are now available for installation
at the company's network of factory-owned service centers.
Introduced at last summer's EAA AirVenture, the King Air 90x
upgrade is a two-part conversion that synergizes the aerodynamic
benefits of winglets with a gross weight increase to create
enhanced King Air 90 handling/range/payload capability. HBS is
offering the upgrades individually or combined in a competitively
"The King Air 90x package provides added value and versatility to
an aircraft that already has a well-deserved reputation as a
workhorse," said Christi Tannahill, HBC vice president, Global
Customer Support. "By combining the upgrades and accomplishing the
modifications during a single service event, operators can
effectively multiply the return on their investment several times
over. Additionally, the performance enhancements gained through the
installation of the winglets will, over time, provide enough fuel
savings to offset much of the cost of the modification."
The winglet system increases wing
aspect ratio to reduce induced drag and allows the King Air to fly
faster on less fuel. By increasing wing surface area, the winglets
provide greater slow speed handling and improved stability at
higher flight levels.
