Special Conditions: Airbus, Model A340-500 and -600 Series Airplanes; \nInteraction of Systems and Structure; Electronic Flight Control System, \nLongitudinal Stability and Low Energy Awareness; and Use of High Incidence \nProtection and Alpha-Floor Systems

These special conditions are issued for the Airbus Model A340-500 and -600 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 associated with the systems that affect the structural performance of the airplane; the electronic flight control system (EFCS); and the use of high incidence protection and alpha-floor systems. 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.
