We propose special conditions for Airbus Helicopters Model AS350B2 and AS350B3 helicopters. These helicopters as modified by Garmin International, Inc., (Garmin) will have a novel or unusual design feature associated with the Garmin Flight Control (GFC) 600H autopilot with stability and control augmentation system (AP/SCAS). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
