The Model 747–8 and the Model 747–8F are derivatives of the 747–400 and the 747– 400F, respectively. Both the Model 747– 8 and the Model 747–8F are four-engine jet transport airplanes that will have a maximum takeoff weight of 975,000 pounds and new General Electric GEnx –2B67 engines. The Model 747–8 will have two flight crew and the capacity to carry 660 passengers. Type Certification Basis Under the provisions of Title 14, Code of Federal Regulations (14 CFR) 21.101, Boeing must show that the Model 747– 8 and 747–8F (hereafter referred as 747– 8/–8F series) meet the applicable provisions of part 25, as amended by Amendments 25–1 through 25–117, 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/–8F. In addition, the certification basis includes other regulations, special conditions and exemptions that are not relevant to these proposed special conditions. Type Certificate No. A20WE will be updated to include a complete description of the certification basis for these airplanes. If the Administrator finds that the applicable airworthiness regulations (i.e., 14 CFR part 25) do not contain adequate or appropriate safety standards for the 747–8/–8F because of a novel or unusual design feature, special conditions are prescribed under the provisions of § 21.16. In addition to the applicable airworthiness regulations and special conditions, the 747–8/–8F series must comply with the fuel vent and exhaust emission requirements of 14 CFR part 34 and the noise certification requirements of 14 CFR part 36. Special conditions, as defined in § 11.19, are issued under § 11.38, and become part of the type certification basis under § 21.101. Special conditions are initially applicable to the model for which they are issued. Should the type certificate for that model be amended later to include any other model or series that incorporates the same or similar novel or unusual design feature, or should any VerDate Nov<24>2008 17:02 Oct 07, 2009 Jkt 220001 other model or series already included on the same type certificate be modified to incorporate the same or similar novel or unusual design feature, the special conditions would also apply to the other model or series under § 21.101. New or Unusual Design Features The Boeing Model 747–8/–8F will incorporate the following novel or unusual design features: An electronic flight control system that provides roll control of the airplane through pilot inputs to the flight computers. Discussion The 747–8/–8F is equipped with an electronic flight control system that provides roll control of the airplane through pilot inputs to the flight computers. Current part 25 airworthiness regulations account for ‘‘control laws,’’ for which aileron deflection is proportional to control wheel deflection. They do not address any nonlinearities 1 or other effects on aileron and spoiler actuation that may be caused by electronic flight controls. Therefore, the FAA considers the flight control system to be a novel and unusual feature compared to those envisioned when current regulations were adopted. Since this type of system may affect flight loads, and therefore the structural capability of the airplane, special conditions are needed to address these effects. These proposed special conditions differ from current requirements in that the special conditions require that the roll maneuver result from defined movements of the cockpit roll control as opposed to defined aileron deflections. Also, these proposed special conditions require an additional load condition at design maneuvering speed (VA), in which the cockpit roll control is returned to neutral following the initial roll input. These proposed special conditions differ from similar special conditions applied to previous designs. These special conditions are limited to the roll axis only, whereas previous special conditions also included pitch and yaw axes. A special condition is no longer needed for the yaw axis because § 25.351 was revised at Amendment 25– 91 to take into account effects of an electronic flight control system. No special condition is needed for the pitch axis because the current requirement (§ 25.331(c)) is adequate. 1 A nonlinearity is a situation where output does not change in the same proportion as input. PO 00000 Frm 00015 Fmt 4702 Sfmt 4702 Applicability As discussed above, these proposed special conditions are applicable to Boeing Model 747–8/–8F airplanes. Should Boeing apply at a later date for a change to the type certificate to include another model incorporating the same novel or unusual design features, these proposed special conditions would apply to that model as well under the provisions of § 21.101. Conclusion This action affects only certain novel or unusual design features of the Boeing Model 747–8/–8F airplanes. It is not a rule of general applicability.

In addition, conditions corresponding to maximum angular acceleration must be investigated. For the angular acceleration conditions, zero rolling velocity may be assumed in the absence of a rational time history investigation of the maneuver. (b) At VA , sudden movement of the cockpit roll control up to the limit is assumed.

Introduction Acting pursuant to these authorities, the Postal Rate Commission established a number of procedures and adopted rules of practice. Among the procedures regularly used by the Commission and presiding officers in proceedings over the years has been the procedure of issuing information requests. Such requests have been routinely issued to obtain information that supplemented, clarified or more fully explained information presented by, or positions taken by, the Postal Service and other participants in Commission proceedings. In addition, the Commission’s original rules of practice were codified as 39 CFR part 3001. Rule 3 of those rules states that ‘‘[t]he rules of practice in this part are applicable to proceedings before the * * * Commission under the Act, This notice of proposed rulemaking is the latest in a series of actions being taken by the Postal Regulatory Commission (Commission) to implement provisions of the Postal Accountability and Enhancement Act (PAEA), Public Law 109–435, 120 Stat. 1 Section 601(a)(3) of the PAEA created section 504 by re-designating then-existing section 3604 of title 39 as section 504. 2 Sections 601(a)(3), 604(a) and 1010(c)(1) of the PAEA renumbered section 3603 of the PRA as § 503 and amended § 503 by, inter alia, replacing ‘‘Postal Rate Commission’’ with ‘‘Postal Regulatory Commission.’’ FOR FURTHER INFORMATION CONTACT: Stephen L.

Prior to passage of the PAEA, there were occasions on which the Commission and the Postal Service could not agree on whether certain information requested by the Commission had to be produced. While in most cases the Commission and the Postal Service were able to resolve their disagreements in a mutually satisfactory manner, there were cases in which disagreements proved to be irreconcilable. In those instances, the Postal Service’s refusal to provide information delayed and complicated the Commission’s ability to carry out its duties.3 The Postal Service’s refusal to provide the requested information forced the Commission to rely upon alternate and less desirable information in order to carry out its statutory responsibilities. The Commission’s inability to obtain the specific information it had requested in those cases was ultimately due to the fact that the Commission could not enforce its orders. Neither the PRA, nor the Administrative Procedure Act (APA), authorized the Commission to seek a court order directing production of the requested information.

Background

    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 and the new Model 
747-8F freighter airplane. The Model 747-8 and the Model 747-8F are 
derivatives of the 747-400 and the 747-400F, respectively. Both the 
Model 747-8 and the Model 747-8F are four-engine jet transport 
airplanes that will have a maximum takeoff weight of 975,000 pounds and 
new General Electric GEnx -2B67 engines. The Model 747-8 will have two 
flight crew and the capacity to carry 660 passengers.

Type Certification Basis

    Under the provisions of Title 14, Code of Federal Regulations (14 
CFR) 21.101, Boeing must show that the Model 747-8 and 747-8F 
(hereafter referred as 747-8/-8F series) meet the applicable provisions 
of part 25, as amended by Amendments 25-1 through 25-117, 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/-8F.
    In addition, the certification basis includes other regulations, 
special conditions and exemptions that are not relevant to these 
proposed special conditions. Type Certificate No. A20WE will be updated 
to include a complete description of the certification basis for these 
airplanes.
    If the Administrator finds that the applicable airworthiness 
regulations (i.e., 14 CFR part 25) do not contain adequate or 
appropriate safety standards for the 747-8/-8F because of a novel or 
unusual design feature, special conditions are prescribed under the 
provisions of Sec.  21.16.
    In addition to the applicable airworthiness regulations and special 
conditions, the 747-8/-8F series must comply with the fuel vent and 
exhaust emission requirements of 14 CFR part 34 and the noise 
certification requirements of 14 CFR part 36.
    Special conditions, as defined in Sec.  11.19, are issued under 
Sec.  11.38, and become part of the type certification basis under 
Sec.  21.101.
    Special conditions are initially applicable to the model for which 
they are issued. Should the type certificate for that model be amended 
later to include any other model or series that incorporates the same 
or similar novel or unusual design feature, or should any other model 
or series already included on the same type certificate be modified to 
incorporate the same or similar novel or unusual design feature, the 
special conditions would also apply to the other model or series under 
Sec.  21.101.

New or Unusual Design Features

    The Boeing Model 747-8/-8F will incorporate the following novel or 
unusual design features: An electronic flight control system that 
provides roll control of the airplane through pilot inputs to the 
flight computers.

Discussion

    The 747-8/-8F is equipped with an electronic flight control system 
that provides roll control of the airplane through pilot inputs to the 
flight computers. Current part 25 airworthiness regulations account for 
``control laws,'' for which aileron deflection is proportional to 
control wheel deflection. They do not address any nonlinearities \1\ or 
other effects on aileron and spoiler actuation that may be caused by 
electronic flight controls. Therefore, the FAA considers the flight 
control system to be a novel and unusual feature compared to those 
envisioned when current regulations were adopted. Since this type of 
system may affect flight loads, and therefore the structural capability 
of the airplane, special conditions are needed to address these 
effects.
---------------------------------------------------------------------------

    \1\ A nonlinearity is a situation where output does not change 
in the same proportion as input.
---------------------------------------------------------------------------

    These proposed special conditions differ from current requirements 
in that the special conditions require that the roll maneuver result 
from defined movements of the cockpit roll control as opposed to 
defined aileron deflections. Also, these proposed special conditions 
require an additional load condition at design maneuvering speed 
(VA), in which the cockpit roll control is returned to 
neutral following the initial roll input.
    These proposed special conditions differ from similar special 
conditions applied to previous designs. These special conditions are 
limited to the roll axis only, whereas previous special conditions also 
included pitch and yaw axes. A special condition is no longer needed 
for the yaw axis because Sec.  25.351 was revised at Amendment 25-91 to 
take into account effects of an electronic flight control system. No 
special condition is needed for the pitch axis because the current 
requirement (Sec.  25.331(c)) is adequate.

Applicability

    As discussed above, these proposed special conditions are 
applicable to Boeing Model 747-8/-8F airplanes. Should Boeing apply at 
a later date for a change to the type certificate to include another 
model incorporating the same novel or unusual design features, these 
proposed special conditions would apply to that model as well under the 
provisions of Sec.  21.101.

Conclusion

    This action affects only certain novel or unusual design features 
of the Boeing Model 747-8/-8F airplanes. It is not a rule of general 
applicability.

The Proposed Special Conditions

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration (FAA) proposes the 
following special conditions as part of the type certification basis 
for the Boeing Model 747-8/-8F series airplanes.
    In lieu of compliance with Sec.  25.349(a), the Boeing Model 747-8/
-8F must comply with the following special conditions.
    The following conditions, speeds, and cockpit roll control motions 
(except as the motions may be limited by pilot effort) must be 
considered in combination with an airplane load factor of zero, and 
separately, two-thirds of the positive maneuvering factor used in 
design. In determining the resulting control surface deflections, the 
torsional flexibility of the wing must be considered in accordance with 
Sec.  25.301(b):
    (a) Conditions corresponding to steady rolling velocities must be 
investigated. In addition, conditions corresponding to maximum angular 
acceleration must be investigated. For the angular acceleration 
conditions, zero rolling velocity may be assumed in the absence of a 
rational time history investigation of the maneuver.
    (b) At VA , sudden movement of the cockpit roll control 
up to the limit is assumed. The position of the cockpit roll control 
must be maintained until a steady roll rate is achieved and then must 
be returned suddenly to the neutral position.
    (c) At VC , the cockpit roll control must be moved
