Abstract
These special conditions are issued for the modification of the Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model EC135 series helicopters. These model helicopters will have a novel or unusual design feature after installation of the S-TEC Corporation (S- TEC) HeliSAS helicopter autopilot/stabilization augmentation system (AP/SAS) that has potential failure conditions with more severe adverse consequences than those envisioned by the existing applicable airworthiness regulations. These special conditions contain the added safety standards the Administrator considers necessary to ensure the failures and their effects are sufficiently analyzed and contained.
