Haggan Aviation receives Lear ZR retrofit approval
Haggan Aviation on Denver’s Centennial Airport has become an authorized installation facility for the Raisbeck ZR light performance system for 30-series Learjets. The ZR light (batwing) performance system modifies the flap contours and installs the batwing at the wing junction with the tiptank.
According to Raisbeck, the modifications improve airflow over the wing and reduce drag, resulting in improved runway performance and increased rate of climb, payload capacity and range. The company estimates that fuel savings alone will pay for the modification in four years based on annual utilization of 500 hours. Haggan Aviation has installed the ZR light on a Learjet 36 in conjunction with the Avcon tiptank extensions and delta fins.
