The UK Civil Aviation Authority has given a nod to Horizon Design Services’ approved model list supplemental type certificate (AML-STC) for installation of Avidyne IFD navigators in nine helicopter models. This approval, which was also validated by the FAA, covers the replacement of Garmin GNS navigators with Avidyne’s IFD-series FMS/GPS navigators in the Airbus Helicopters AS350, AS355, EC120, EC130, and EC135; Leonardo A109 and A119; and Bell 206 and 407.
Development of the AML-STC simplifies the replacement process, so avionics dealers and maintenance facilities don’t have to go through the time-consuming field approval process. “We are making this STC package available for helicopter MROs at a nominal cost, allowing for an easier transition from obsolete GNS systems to the highly capable Avidyne IFD-series slide-in replacement navigators,” said Michael Hodby, managing director of Horizon Design Services. The price of the AML-STC package is $2,500.
