    Description of modification

    A Mode S Transponder is necessary in many airspaces and wherever ADS-B regulations are in force.

Heli-One offers the MST-67A Mode S Transponder as a retrofit in the AS332. In addition to the MST-67A this modification installs the PS-578A control head, a new DMNI antenna and a Sandia SAC 7-35 Airdata computer. Interfacing to existing aircraft systems is included (pitot-statics, DME coupler etc).
