Background On March 10, 2014, Game Composite Ltd. applied for a type certificate for their new GB1 airplane. The GB1 is a E:\FR\FM\03JYP1.SGM 03JYP1 Federal Register / Vol. 82, No. 126 / Monday, July 3, 2017 / Proposed Rules sradovich on DSK3GMQ082PROD with PROPOSALS single-engine airplane with a two-place tandem canopy cockpit. It features conventional landing gear, conventional low-wing planform, and is mostly constructed of carbon composite materials. The engine is a Lycoming AEIO–580–B1A, fitted with a model MTV–14–B–C/C190–130 4–blade MTpropeller. The airplane will be approved for Day-VFR operations (non-icing). The maximum takeoff weight is 2,200 pounds in acrobatic category with a maximum operating altitude of 15,000 feet. The never exceed speed (VNE) is 230 knots, the design cruise speed (VC) is 200 knots, and the design maneuvering speed (VA) is 175 knots. Acrobatic airplanes previously type certified by the FAA did comply with the stability provisions of part 23, subpart B. However, airplanes like the GB1 are considered as ‘‘unlimited’’ acrobatic airplanes because these airplanes can perform all the maneuvers listed in the Aresti Catalog. Generally, the evolution of the ‘‘unlimited’’ types of acrobatic airplanes, with very low mass, exceptional roll rates, and very high G capabilities—in addition to power to mass ratios—are unique to this type of airplane and have led to airplanes that cannot comply with the stability provisions of the regulations. These airplanes can be type certified in the acrobatic category only with an appropriate set of special conditions and associated limitations. Type Certification Basis Under the provisions of 14 CFR 21.17, Game Composites Ltd. must show the GB 1 meets the applicable provisions of part 23, as amended by amendments 23–1 through 23–62 thereto. If the Administrator finds that the applicable airworthiness regulations (i.e., 14 CFR part 23) do not contain adequate or appropriate safety standards for the GB1 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 or similar novel or unusual design feature, the FAA would apply these special conditions to the other model under § 21.101. In addition to the applicable airworthiness regulations and special conditions, the GB1 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 and the FAA must issue a finding of regulatory adequacy under VerDate Sep<11>2014 16:50 Jun 30, 2017 Jkt 241001 § 611 of Public Law 92–574, the ‘‘Noise Control Act of 1972.’’. 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 § 21.17(a)(2). Novel or Unusual Design Features The GB1 airplane will incorporate the following novel or unusual design features: For acrobatic category airplanes with unlimited acrobatic capability: Relaxed longitudinal and decoupled lateral static stability characteristics Discussion Sections 23.173 and 23.177 provide static stability criteria for longitudinal, lateral, and directional axes requirements for an airplane. However, these requirements are not adequate to address the specific issues raised in the flight characteristics of an unlimited aerobatic airplane. Therefore, the FAA has determined special conditions are needed—after a flight-test evaluation— to address the static stability characteristics of the GB1. Accordingly, these special conditions are for the Game Composites Ltd. GB1 airplane’s static stability characteristics. Applicability As discussed above, these special conditions are applicable to the GB1. Should Game Composites Ltd. apply at a later date for a change to the type certificate to include another model incorporating the same novel or unusual design feature the FAA would apply these special conditions to that model as well. Conclusion This action affects only certain novel or unusual design features on one model of airplane. It is not a rule of general applicability.

In place of 14 CFR 23.173, ‘‘Static longitudinal stability,’’ comply with the following: ■ SC23.173 Static Longitudinal Stability Under the conditions in 14 CFR 23.175 and with the airplane trimmed as indicated, the characteristics of the elevator control forces and the friction within the control system must be as follows: (a) A pull must be required to obtain and maintain speeds below the specified trim speed and a push required to obtain and maintain speeds above the specified trim speed. This must be shown at any speed that can be obtained, except that speeds requiring a control force in excess of 40 pounds or speeds above the maximum allowable speed or below the minimum speed for steady unstalled flight need not be considered. (b) The stick force or position must vary with speed so any substantial speed change results in a stick force or position clearly perceptible to the pilot. ■ b. In place of 14 CFR 23.177, ‘‘Static directional and lateral stability,’’ comply with the following: SC23.177 Static Directional and Lateral Stability (a) The static directional stability, as shown by the tendency to recover from a wings level sideslip with the rudder free, must be positive for any landing gear and flap position appropriate to the takeoff, climb, cruise, approach, and landing configurations. This must be shown with symmetrical power up to maximum continuous power and at speeds from 1.2 VS1 to VO (maximum operating maneuvering speed); the rudder pedal force must not reverse. (b) In straight, steady slips at 1.2 VS1 for any landing gear and flap positions and for any symmetrical power conditions up to 50 percent of maximum continuous power, the rudder control movements and forces must increase steadily—but not necessarily in constant proportion—as the angle of sideslip is increased is increased up to the maximum appropriate for the type of airplane. The aileron control movements and forces may increase steadily, but not necessarily in constant proportion, as the angle of sideslip is increased up to the maximum appropriate for the type of airplane. At larger slip angles, up to the angle at which full rudder or aileron control is used or a control force limit contained in 14 CFR 23.143 is reached, the aileron and rudder control movements and forces must not reverse as the angle of sideslip is increased.

We will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. We may change these special conditions based on the comments we receive. Background On April 19, 2011, SNECMA, now known as SAE, applied for a type certificate for the Silvercrest-2 SC–2D engine model. On April 30, 2014, SAE requested an extension to their original type certificate application, which the FAA granted through June 30, 2015. On May 26, 2015, SAE requested another extension to their type certificate application, which the FAA granted through September 30, 2018. SAE proposed an additional takeoff rating to maintain takeoff thrust in certain high ambient temperature conditions with all engines operating (AEO) for the Silvercrest-2 SC–2D engine model. Therefore, the Silvercrest-2 SC–2D engine model would have two different takeoff ratings. The first rating corresponds with the rated takeoff thrust of the engine. The second takeoff rating maintains the takeoff thrust in certain high ambient temperature conditions. This additional takeoff rating is named ‘‘Rated Takeoff Thrust at High Ambient Temperature’’ (Rated TOTHAT). The Rated TOTHAT is an approved engine thrust developed under specified altitudes and temperatures within the operating limitations established for the engine during takeoff operation for a maximum usage of 20 minutes in any one flight. Type Certification Basis Under the provisions of title 14, Code of Federal Regulations (14 CFR) 21.17, SAE must show that the Silvercrest-2 SC–2D meets the applicable provisions of 14 CFR part 33, as amended by Amendments 33–1 through 33–34 in effect on the date of application. If the FAA finds that the applicable airworthiness regulations do not contain adequate or appropriate safety standards for the Silvercrest-2 SC–2D engine model, 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.

Background

    On March 10, 2014, Game Composite Ltd. applied for a type 
certificate for their new GB1 airplane. The GB1 is a

[[Page 30799]]

single-engine airplane with a two-place tandem canopy cockpit. It 
features conventional landing gear, conventional low-wing planform, and 
is mostly constructed of carbon composite materials. The engine is a 
Lycoming AEIO-580-B1A, fitted with a model MTV-14-B-C/C190-130 4-blade 
MT-propeller. The airplane will be approved for Day-VFR operations 
(non-icing). The maximum takeoff weight is 2,200 pounds in acrobatic 
category with a maximum operating altitude of 15,000 feet. The never 
exceed speed (VNE) is 230 knots, the design cruise speed 
(VC) is 200 knots, and the design maneuvering speed 
(VA) is 175 knots.
    Acrobatic airplanes previously type certified by the FAA did comply 
with the stability provisions of part 23, subpart B. However, airplanes 
like the GB1 are considered as ``unlimited'' acrobatic airplanes 
because these airplanes can perform all the maneuvers listed in the 
Aresti Catalog. Generally, the evolution of the ``unlimited'' types of 
acrobatic airplanes, with very low mass, exceptional roll rates, and 
very high G capabilities--in addition to power to mass ratios--are 
unique to this type of airplane and have led to airplanes that cannot 
comply with the stability provisions of the regulations. These 
airplanes can be type certified in the acrobatic category only with an 
appropriate set of special conditions and associated limitations.

Type Certification Basis

    Under the provisions of 14 CFR 21.17, Game Composites Ltd. must 
show the GB 1 meets the applicable provisions of part 23, as amended by 
amendments 23-1 through 23-62 thereto.
    If the Administrator finds that the applicable airworthiness 
regulations (i.e., 14 CFR part 23) do not contain adequate or 
appropriate safety standards for the GB1 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 or similar 
novel or unusual design feature, the FAA would apply these special 
conditions to the other model under Sec.  21.101.
    In addition to the applicable airworthiness regulations and special 
conditions, the GB1 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 and the FAA must issue a finding of regulatory 
adequacy under Sec.  611 of Public Law 92-574, the ``Noise Control Act 
of 1972.''.
    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.  21.17(a)(2).

Novel or Unusual Design Features

    The GB1 airplane will incorporate the following novel or unusual 
design features:
    For acrobatic category airplanes with unlimited acrobatic 
capability:
    Relaxed longitudinal and decoupled lateral static stability 
characteristics

Discussion

    Sections 23.173 and 23.177 provide static stability criteria for 
longitudinal, lateral, and directional axes requirements for an 
airplane. However, these requirements are not adequate to address the 
specific issues raised in the flight characteristics of an unlimited 
aerobatic airplane. Therefore, the FAA has determined special 
conditions are needed--after a flight-test evaluation--to address the 
static stability characteristics of the GB1. Accordingly, these special 
conditions are for the Game Composites Ltd. GB1 airplane's static 
stability characteristics.

Applicability

    As discussed above, these special conditions are applicable to the 
GB1. Should Game Composites Ltd. apply at a later date for a change to 
the type certificate to include another model incorporating the same 
novel or unusual design feature the FAA would apply these special 
conditions to that model as well.

Conclusion

    This action affects only certain novel or unusual design features 
on one model of airplane. It is not a rule of general applicability.

List of Subjects in 14 CFR Part 23

    Aircraft, Aviation safety, Signs and symbols.

    The authority citation for these special conditions is as follows:

    Authority: 49 U.S.C. 106(f), 106(g), 40113, 44701, 44702, 44704.

The Proposed Special Conditions

    Accordingly, the Federal Aviation Administration (FAA) proposes the 
following special condition as part of the type certification basis for 
Game Composites GB1 airplanes.

0
1. Acrobatic Only Category Static Stability Requirements.
0
a. In place of 14 CFR 23.173, ``Static longitudinal stability,'' comply 
with the following:

SC23.173 Static Longitudinal Stability

    Under the conditions in 14 CFR 23.175 and with the airplane trimmed 
as indicated, the characteristics of the elevator control forces and 
the friction within the control system must be as follows:
    (a) A pull must be required to obtain and maintain speeds below the 
specified trim speed and a push required to obtain and maintain speeds 
above the specified trim speed. This must be shown at any speed that 
can be obtained, except that speeds requiring a control force in excess 
of 40 pounds or speeds above the maximum allowable speed or below the 
minimum speed for steady unstalled flight need not be considered.
    (b) The stick force or position must vary with speed so any 
substantial speed change results in a stick force or position clearly 
perceptible to the pilot.
0
b. In place of 14 CFR 23.177, ``Static directional and lateral 
stability,'' comply with the following:

SC23.177 Static Directional and Lateral Stability

    (a) The static directional stability, as shown by the tendency to 
recover from a wings level sideslip with the rudder free, must be 
positive for any landing gear and flap position appropriate to the 
takeoff, climb, cruise, approach, and landing configurations. This must 
be shown with symmetrical power up to maximum continuous power and at 
speeds from 1.2 VS1 to VO (maximum operating 
maneuvering speed); the rudder pedal force must not reverse.
    (b) In straight, steady slips at 1.2 VS1 for any landing 
gear and flap positions and for any symmetrical power conditions up to 
50 percent of maximum continuous power, the rudder control movements 
and forces must increase steadily--but not necessarily in constant 
proportion--as the angle of sideslip is increased is increased up to
