The Model 737–8 airplane is a narrow-body, transport-category airplane that is a derivative of the Model 737–800 airplane with two CFM LEAP–1B wingmounted engines. The Model 737–8 airplane will include electronic flight controls that affect maneuvering. The current design roll-maneuver requirements in Title 14, Code of Federal Regulations (14 CFR) part 25 are inadequate for addressing an airplane with electronic flight controls that affect maneuvering. These special conditions adjust the current roll-maneuver requirement, § 25.349, to take into account the effects of an electronic flight-control system. Type Certification Basis Under the provisions of § 21.101, The Boeing Company must show that the Model 737–8 series airplanes meet the applicable provisions of the regulations listed in type certificate no. A16WE, or the applicable regulations in effect on the date of application for the change except for earlier amendments as agreed upon by the FAA. The regulations listed in the type certificate are commonly referred to as the ‘‘original type-certification basis.’’ The regulations listed in type certificate no. A16WE are as follows: 14 CFR part 25, effective February 1, 1965, including Amendments 25–1 through 25–134. In addition, the VerDate Sep<11>2014 14:09 Feb 10, 2016 Jkt 238001 certification basis includes certain special conditions, exemptions, or later amended sections of the applicable part that are not relevant to these special conditions. 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 Model 737–8 series airplanes because of a novel or unusual design feature, special conditions are prescribed under the provisions of § 21.16. 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 that incorporates the same novel or unusual design feature, or should any other model already included on the same type certificate be modified to incorporate the same novel or unusual design feature, these special conditions would also apply to the other model under § 21.101. In addition to the applicable airworthiness regulations and special conditions, the Model 737–8 series airplanes must comply with the fuelvent and exhaust-emission requirements of 14 CFR part 34, and the noisecertification requirements of 14 CFR part 36. The FAA issues special conditions, as defined in 14 CFR 11.19, in accordance with § 11.38, and they become part of the type-certification basis under § 21.101. Novel or Unusual Design Features The Model 737–8 series airplanes will incorporate the following novel or unusual design features: The airplanes are equipped with an electronic flight-control system that provides control through pilot inputs to the flight computer. Current part 25 airworthiness regulations account for control laws for which aileron deflection is proportional to control-stick deflection. They do not address nonlinearities or other effects on aileron actuation that electronic flight controls may cause. Because this type of system may affect flight loads, and therefore the structural capability of the airplanes, special conditions are needed to address these effects. Discussion These special conditions differ from current requirements in that they require that the roll maneuver is based on defined actuation of the cockpit roll control as opposed to defined deflections of the aileron itself. Also, the special conditions require an additional load condition at VA, in which the cockpit roll control is returned to neutral following the initial roll input. PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 7199 These special conditions differ from similar special conditions applied on previous programs. These special conditions are limited to the roll axis only, whereas previous special conditions also included the pitch and yaw axes. Special conditions are no longer needed for the pitch or yaw axes, because Amendment 25–91 takes into account the effects of an electronic flight-control system in those axes (§ 25.331 for pitch and § 25.351 for yaw). On the Model 737–8 series airplanes, only the flight spoilers are flyby-wire. 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. Applicability As discussed above, these special conditions are applicable to the Boeing Model 737–8 series 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 feature, these special conditions would apply to that model as well. Conclusion This action affects only certain novel or unusual design features on Boeing Model 737–8 series airplanes. It is not a rule of general applicability. The substance of these special conditions has been subjected to the notice and comment period in several prior instances and has been derived without substantive change from those previously issued. It is unlikely that prior public comment would result in a significant change from the substance contained herein. Therefore, because a delay would significantly affect the certification of the airplane, the FAA has determined that prior public notice and comment are unnecessary and impracticable, and good cause exists for adopting these special conditions upon publication in the Federal Register. The FAA is requesting comments to allow interested persons to submit views that may not have been submitted in response to the prior opportunities for comment described above.

DATES: In lieu of compliance to § 25.349(a): 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 of two-thirds of the positive maneuvering factor used in design. In determining the resulting controlsurface deflections, the torsional flexibility of the wing must be considered in accordance with § 25.301(b): 1. The applicant must investigate conditions corresponding to steady rolling velocities. In addition, conditions corresponding to maximum angular acceleration must be investigated for airplanes with engines or other weight concentrations outboard of the fuselage. For the angular acceleration conditions, zero rolling velocity may be assumed in the absence of a rational time-history investigation of the maneuver. 2. 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. 3. At VC, the cockpit roll control must be moved suddenly and maintained so as to achieve a roll rate not less than that obtained in Special Condition 2, above. 4. At VD, the cockpit roll control must be moved suddenly and maintained so as to achieve a roll rate not less than one third of that obtained in Special Condition 2, above.

ACTION: Final rule. AGENCY: This action establishes Class E airspace extending upward from 700 SUMMARY: VerDate Sep<11>2014 14:09 Feb 10, 2016 Jkt 238001 The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. Subtitle I, Section 106 describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the agency’s authority. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it establishes PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 Class E airspace at Clinton Municipal Airport, Clinton, AR. History On November 30, 2015, the FAA published in the Federal Register a notice of proposed rulemaking (NPRM) to establish Class E airspace extending upward from 700 feet above the surface at Clinton Municipal Airport, Clinton, AR. (80 FR 74736). Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. No comments were received. The FAA also notes that in the NPRM, the state identifier was incorrectly written as LA, and is corrected in the airspace description to AR. Class E airspace designations are published in paragraph 6005 of FAA Order 7400.9Z, dated August 6, 2015, and effective September 15, 2015, which is incorporated by reference in 14 CFR part 71.1. The Class E airspace designations listed in this document will be published subsequently in the Order. Availability and Summary of Documents for Incorporation by Reference This document amends FAA Order 7400.9Z, Airspace Designations and Reporting Points, dated August 6, 2015, and effective September 15, 2015. FAA Order 7400.9Z is publicly available as listed in the ADDRESSES section of this document. FAA Order 7400.9Z lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points. The Rule This action amends Title 14, Code of Federal Regulations (14 CFR), Part 71 by establishing Class E airspace extending upward from 700 feet above the surface within a 6.0-mile radius of Clinton Municipal Airport, Clinton, AR, to accommodate new Standard Instrument Approach Procedures for IFR operations at the airport. Also, the correct state identifier is noted in the airspace description, changing it from LA to AR. Regulatory Notices and Analyses The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current, is non-controversial and unlikely to result in adverse or negative comments. It, therefore: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 E:\FR\FM\11FER1.SGM 11FER1

would significantly delay issuance of the design approval and thus 
delivery of the affected airplane.
    In addition, the substance of these special conditions has been 
subject to the public comment process in several prior instances with 
no substantive comments received. The FAA therefore finds that good 
cause exists for making these special conditions effective upon 
publication in the Federal Register.

Comments Invited

    We invite interested people to take part in this rulemaking by 
sending written comments, data, or views. The most helpful comments 
reference a specific portion of the special conditions, explain the 
reason for any recommended change, and include supporting data.
    We will consider all comments we receive by the closing date for 
comments. We may change these special conditions based on the comments 
we receive.

Background

    On January 27, 2012, The Boeing Company applied for an amendment to 
Type Certificate No. A16WE to include a new Model 737-8 airplane. The 
Model 737-8 airplane is a narrow-body, transport-category airplane that 
is a derivative of the Model 737-800 airplane with two CFM LEAP-1B 
wing-mounted engines.
    The Model 737-8 airplane will include electronic flight controls 
that affect maneuvering.
    The current design roll-maneuver requirements in Title 14, Code of 
Federal Regulations (14 CFR) part 25 are inadequate for addressing an 
airplane with electronic flight controls that affect maneuvering. These 
special conditions adjust the current roll-maneuver requirement, Sec.  
25.349, to take into account the effects of an electronic flight-
control system.

Type Certification Basis

    Under the provisions of Sec.  21.101, The Boeing Company must show 
that the Model 737-8 series airplanes meet the applicable provisions of 
the regulations listed in type certificate no. A16WE, or the applicable 
regulations in effect on the date of application for the change except 
for earlier amendments as agreed upon by the FAA.
    The regulations listed in the type certificate are commonly 
referred to as the ``original type-certification basis.'' The 
regulations listed in type certificate no. A16WE are as follows:
    14 CFR part 25, effective February 1, 1965, including Amendments 
25-1 through 25-134. In addition, the certification basis includes 
certain special conditions, exemptions, or later amended sections of 
the applicable part that are not relevant to these special conditions.
    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 Model 737-8 series airplanes 
because of a novel or unusual design feature, special conditions are 
prescribed under the provisions of Sec.  21.16.
    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 that incorporates the same novel or 
unusual design feature, or should any other model already included on 
the same type certificate be modified to incorporate the same novel or 
unusual design feature, these special conditions would also apply to 
the other model under Sec.  21.101.
    In addition to the applicable airworthiness regulations and special 
conditions, the Model 737-8 series airplanes 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.
    The FAA issues special conditions, as defined in 14 CFR 11.19, in 
accordance with Sec.  11.38, and they become part of the type-
certification basis under Sec.  21.101.

Novel or Unusual Design Features

    The Model 737-8 series airplanes will incorporate the following 
novel or unusual design features:

    The airplanes are equipped with an electronic flight-control 
system that provides control through pilot inputs to the flight 
computer. Current part 25 airworthiness regulations account for 
control laws for which aileron deflection is proportional to 
control-stick deflection. They do not address nonlinearities or 
other effects on aileron actuation that electronic flight controls 
may cause. Because this type of system may affect flight loads, and 
therefore the structural capability of the airplanes, special 
conditions are needed to address these effects.

Discussion

    These special conditions differ from current requirements in that 
they require that the roll maneuver is based on defined actuation of 
the cockpit roll control as opposed to defined deflections of the 
aileron itself. Also, the special conditions require an additional load 
condition at VA, in which the cockpit roll control is 
returned to neutral following the initial roll input.
    These special conditions differ from similar special conditions 
applied on previous programs. These special conditions are limited to 
the roll axis only, whereas previous special conditions also included 
the pitch and yaw axes. Special conditions are no longer needed for the 
pitch or yaw axes, because Amendment 25-91 takes into account the 
effects of an electronic flight-control system in those axes (Sec.  
25.331 for pitch and Sec.  25.351 for yaw). On the Model 737-8 series 
airplanes, only the flight spoilers are fly-by-wire.
    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.

Applicability

    As discussed above, these special conditions are applicable to the 
Boeing Model 737-8 series 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 feature, these special 
conditions would apply to that model as well.

Conclusion

    This action affects only certain novel or unusual design features 
on Boeing Model 737-8 series airplanes. It is not a rule of general 
applicability.
    The substance of these special conditions has been subjected to the 
notice and comment period in several prior instances and has been 
derived without substantive change from those previously issued. It is 
unlikely that prior public comment would result in a significant change 
from the substance contained herein. Therefore, because a delay would 
significantly affect the certification of the airplane, the FAA has 
determined that prior public notice and comment are unnecessary and 
impracticable, and good cause exists for adopting these special 
conditions upon publication in the Federal Register. The FAA is 
requesting comments to allow interested persons to submit views that 
may not have been submitted in response to the prior opportunities for 
comment described above.

    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 of 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):
    1. The applicant must investigate conditions corresponding to 
steady rolling velocities. In addition, conditions corresponding to 
maximum angular acceleration must be investigated for airplanes with 
engines or other weight concentrations outboard of the fuselage. For 
the angular acceleration conditions, zero rolling velocity may be 
assumed in the absence of a rational time-history investigation of 
the maneuver.
    2. 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.
    3. At VC, the cockpit roll control must be moved 
suddenly and maintained so as to achieve a roll rate not less than 
that obtained in Special Condition 2, above.
    4. At VD, the cockpit roll control must be moved 
suddenly and maintained so as to achieve a roll rate not less than 
one third of that obtained in Special Condition 2, above.
