Special Conditions: Embraer S.A.; Model EMB-550 Airplane; Stowage Compartment Fire Protection

These special conditions are issued for the Embraer S.A. Model EMB-550 airplane. This airplane 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 the installation of a stowage compartment in the lavatory. The isolation of this stowage compartment from the main cabin could hinder the ability of the flight crew to detect a fire. 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.
