West Star Aviation in Grand Junction, Colo., is working with the FAA to amend its Learjet 35/36 RVSM STC to include models with the FC-530 autopilot, FC-200 autopilot and Mark IV wings, FC-200 autopilot and non-Softflite Century III wings or FC-531 autopilot and Century III Softflite wings. The amended STC will allow about 70 to 80 additional 30-series Learjets to meet RVSM equipment requirements. The current STC, awarded last August, applies to the Learjet 30 series with the FC-200 autopilot and Softflite wings. West Star Aviation expects the STC amendments to be approved this summer.
