On November 4, 2005, The Boeing Company, PO Box 3707, Seattle, WA, 98124, applied for an amendment to Type Certificate Number A20WE to include the new Model 747-8 series passenger airplane. The Model 747-8 is a derivative of the 747-400. The Model 747-8 is a four-engine jet transport Start Printed Page 31452airplane that will have a maximum takeoff weight of 975,000 pounds, new General Electric GEnx -2B67 engines, and the capacity to carry 605 passengers.
Under the provisions of Title 14, Code of Federal Regulations (14 CFR) 21.101, Boeing must show that the Model 747-8 (hereafter referred as 747-8) meets the applicable provisions of part 25, Amendments 25-1 through 25-120, plus Amendment 25-127 for § 25.795(a), except for earlier amendments as agreed upon by the FAA. These regulations will be incorporated into Type Certificate No. A20WE after type certification approval of the 747-8.
The regulations do not adequately address a passenger airplane with separate decks for passenger occupancy, thus the FAA considers this to be a novel design. Therefore, the FAA has determined that special conditions, in addition to the requirements of §§ 25.803 and 25.811 through 25.813, are required to address the proposed design.
6. The stairway must be designed and located to minimize damage to its structure during an emergency landing or ditching.Start Printed Page 31453
7. General illumination must be provided so, when measured along the center lines of each tread and landing, the illumination is not less than 0.05 foot-candle. This is in lieu of compliance with § 25.812(c), at Amendment 25-116.
8. Means must be provided to assist passengers in locating the stairway in dense smoke conditions as part of compliance with § 25.811(c), at Amendment 25-88.
9. An emergency exit sign meeting § 25.812(b)(1)(i), at Amendment 25-116, must be provided in the upper deck near the stairway visible to passengers approaching along the main aisle as required by § 25.811(d)(1), at Amendment 25-88.
10. Floor proximity lighting required by § 25.812(e), at Amendment 25-120, must be provided along the stairs.
