Special Conditions: Bombardier Aerospace Inc. Model BD-500-1A10 and BD-500-1A11 Airplanes; Flight-Envelope Protection, High Incidence Protection Function

摘要

These special conditions are issued for the Bombardier Aerospace Inc. Model BD-500-1A10 and -A11 airplanes. These airplanes will have a novel or unusual design feature when compared to the state of technology and design envisioned in the airworthiness standards for transport-category airplanes. This design feature is a high incidence protection system that limits the angle of attack at which the airplane can be flown during normal low-speed operation. 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.
