Duncan Aviation’s avionics and instruments department has added several BendixKing product lines to its repair and overhaul capabilities over the past two years, most recently the KS270C/271C/272C. Eric Olson, Duncan Aviation autopilot team leader, says the BendixKing Charlie series is a more advanced servo that uses a surface-mount technology to benefit many Beechcraft, Cessna and Piper models. Duncan Aviation has also developed internal FAA-approved repair procedures to replace parts that are no longer available for the KFC200/250 autopilots.
