Special Conditions: Boeing Model 777-200 Series Airplanes; Overhead Crew Rest Compartment

These amended special conditions are issued to The Boeing Company for Model 777-200 series airplanes, modified by Flight Structures, Inc. This airplane has a novel or unusual design feature associated with the installation of a crew rest compartment. Special Conditions No. 25-169-SC were issued on December 1, 2000, addressing this installation. On January 16, 2001, Flight Structures, Inc., applied for an amendment to these special conditions to allow the assistance of personnel in the main passenger cabin to assist in the evacuation of an incapacitated person from the overhead crew rest compartment to the main passenger cabin. The assistance by persons in the main passenger cabin would reduce the potential for injury to the incapacitated person(s) being lowered from the overhead crew rest area to the main passenger cabin. Since the applicable airworthiness regulations, including those contained in Special Conditions No. 25- 169-SC, 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.
