Special Conditions: Bombardier Inc., Models BD-500-1A10 and BD-500-1A11 series airplanes; Fuselage In-Flight Fire Safety and Flammability Resistance

الملخص

This action proposes special conditions for the Bombardier Inc. Model BD-500-1A10 and BD-500-1A11 series airplanes. These airplanes will have a novel or unusual design feature associated with the materials used to fabricate the fuselage, which may affect fire propagation during an in-flight fire. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed 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.
