Special Conditions: Bombardier Aerospace, Models BD-500-1A10 and BD-500-1A11; Composite Wing and Fuel Tank Structure Post-Crash Fire Survivability

These special conditions are issued for the Bombardier Aerospace, Models BD-500-1A10 and BD-500-1A11 series 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 composite materials used in the construction of the fuel tank skin and structure, which may behave differently in a post-crash fire than traditional aluminum construction. 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.
