Special Conditions: Bombardier Inc. Models BD-700-2A12 and BD-700-2A13 airplanes; Operation Without Normal Electrical Power.

These special conditions are issued for the Bombardier Inc. (Bombardier) Models BD-700-2A12 and BD-700-2A13 airplanes. These airplanes will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. These design features are electrical and electronic systems that perform critical functions, the loss of which could be catastrophic to the airplane. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. 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.
