Special Conditions: Bombardier Aerospace, Model BD-700-2A12 and BD-700-2A13 Airplanes; Limit Engine Torque Loads
These special conditions are issued for the Bombardier (Bombardier) Inc. Models BD-700-2A12 and BD-700-2A13 airplanes. This airplane will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. This design feature is the engine torque- load limit imposed by sudden engine stoppage due to malfunction or structural failure. 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.
