After completing all the necessary test flights in a late-model Learjet 25D this past spring, Avcon Industries now anticipates receipt this month of an STC for the company’s $149,500 Learjet 20-series RVSM package. Five more airplanes (two Learjet 24s and three 25s) will next join the test program in an endeavor that could lead to RVSM group approval of the series by late summer.

Whether Avcon is successful in gaining the coveted group status for the Learjet 24/25, however, hinges on the performance of the series’ original JET FC-110 autopilot, a finicky piece of hardware that in some airplanes has shown an unwillingness to hold altitude to RVSM’s tight tolerances.
