The FAA's summary their words, unchanged

These special conditions are issued for the modification of the Bell Helicopter Textron Canada Limited (Bell) model 407 helicopter. This model helicopter will have novel or unusual design features when modified by installing the Hoh Aeronautics, Inc. (Hoh) complex 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.
