Abstract
These special conditions are issued for the Bell Helicopter Textron Canada Limited (BHTCL) Bell Model 505 helicopter. This helicopter as modified by S-TEC will have a novel or unusual design feature associated with installation of the autopilot and stability augmentation system (AP/SAS system). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These 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.
