Federal Register / Vol. 80, No. 122 / Thursday, June 25, 2015 / Rules and Regulations 36471 

BD–500–1A11 series airplanes (hereafter 

collectively referred to as ‘‘CSeries’’). 

Bombardier later applied for, and was 

granted, an extension of time for the 

type certificate, which changed the 

effective application date to December 

31, 2011. The CSeries airplanes are 

swept-wing monoplanes with an 

aluminum alloy fuselage, sized for 5- 

abreast seating. Passenger capacity is 

110 for the Model BD–500–1A10 and 

125 for the Model BD–500–1A11. The 

airplanes are powered by two 

underwing Pratt and Whitney PW1524G 

ultra-high bypass, geared, turbofan 

engines. Maximum takeoff weight is 

131,000 pounds for the Model BD–500– 

1A10 and 144,000 pounds for the Model 

BD–500–1A11. The CSeries airplanes 

will have a fly-by-wire EFCS. 

Type Certification Basis 

Under the provisions of Title 14, Code 

of Federal Regulations (14 CFR) 21.17, 

Bombardier Aerospace must show that 

the CSeries airplane meets the 

applicable provisions of part 25, as 

amended by Amendments 25–1 through 

25–129. 

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 Bombardier CSeries 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 or similar 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 Bombardier CSeries 

airplane must comply with the fuel-vent 

and exhaust-emission requirements of 

14 CFR part 34, and the noisecertification requirements of 14 CFR 

part 36. The FAA must issue a finding 

of regulatory adequacy under § 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 Bombardier CSeries airplane will 

incorporate the following novel or 

unusual design feature: Fly-by-wire 

EFCS that will limit pitch and roll 

functions to prevent the airplane from 

attaining certain pitch attitudes and roll 

angles greater than plus or minus 65 

degrees, and positive spiral stability 

introduced for roll angles greater than 

30 degrees at speeds below VMO/MMO. 

This system generates the actual surface 

commands that provide for stability 

augmentation and flight control for all 

three airplane axes (longitudinal, lateral, 

and directional). 

Discussion 

Part 25 does not specifically relate to 

flight characteristics associated with 

fixed attitude limits. Bombardier 

proposes to implement on the CSeries 

airplanes pitch and roll attitude-limiting 

functions via the EFCS normal mode. 

This will prevent the airplane from 

attaining certain pitch attitudes and roll 

angles greater than plus or minus 65 

degrees. In addition, positive spiral 

stability, introduced for roll angles 

greater than 30 degrees at speeds below 

VMO/MMO, and spiral stability 

characteristics, must not require 

excessive pilot strength to achieve bank 

angles up to the bank-angle limit. 

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. 

Discussion of Comments 

Notice of proposed special conditions 

no. 25–15–02–SC for the Bombardier 

Model BD–500–1A10 and BD–500– 

1A11 series airplanes was published in 

the Federal Register on February 27, 

2015 (80 FR 10632). No substantive 

comments were received, and the 

special conditions are adopted as 

proposed. 

Applicability 

As discussed above, these special 

conditions are applicable to the 

Bombardier CSeries airplane. Should 

Bombardier Aerospace apply later for a 

change to the type certificate to include 

another model incorporating the same 

or similar 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 

Bombardier CSeries airplanes. It is not 

a rule of general applicability. 

List of Subjects in 14 CFR Part 25 

Aircraft, Aviation safety, Reporting 

and recordkeeping requirements. 

The authority citation for these 

special conditions is as follows: 

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

44702, 44704. 

The Special Conditions 

Accordingly, pursuant to the 

authority delegated to me by the 

Administrator, the following special 

conditions are issued as part of the typecertification basis for the Bombardier 

CSeries airplanes. 

In addition to § 25.143, the following 

requirements apply to the EFCS pitchand roll-limiting functions: 

1. The pitch-limiting function must 

not impede normal maneuvering for 

pitch angles up to the maximum 

required for normal maneuvering, 

including a normal, all-enginesoperating takeoff, plus a suitable margin 

to allow for satisfactory speed control. 

2. The pitch- and roll-limiting 

functions must not restrict or prevent 

attaining pitch attitudes necessary for 

emergency maneuvering, or roll angles 

up to 65 degrees. Spiral stability, which 

is introduced above 30 degrees roll 

angle, must not require excessive pilot 

strength to achieve these roll angles. 

Other protections, which further limit 

the roll capability under certain extreme 

angle-of-attack, attitude, or high-speed 

conditions, are acceptable, as long as 

they allow at least 45 degrees of roll 

capability. 

3. A lower limit of roll is acceptable 

beyond the overspeed warning if it is 

possible to recover the airplane to the 

normal flight envelope without undue 

difficulty or delay.

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking 

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 amends 

Class E airspace at Highmore Municipal 

Airport, Highmore, SD. 

History 

On April 24, 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 Highmore Municipal Airport, 

Highmore, SD, (80 FR 22947). Interested 

parties were invited to participate in 

this rulemaking effort by submitting 

written comments on the proposal to the 

FAA. No comments were received. 

Class E airspace designations are 

published in Paragraphs 6005, of FAA 

Order 7400.9Y, dated August 6, 2014, 

and effective September 15, 2014, which 

is incorporated by reference in 14 CFR 

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 

7400.9Y, airspace Designations and 

Reporting Points, dated August 6, 2014, 

and effective September 15, 2014. FAA 

Order 7400.9Y is publicly available as 

listed in the ADDRESSES section of this 

final rule. FAA Order 7400.9Y 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 6.5-mile radius of Highmore 

Municipal Airport, Highmore, SD, to 

accommodate new Standard Instrument 

Approach Procedures for IFR operations 

at the airport. Additionally, geographic 

coordinates for Highmore Municipal 

airport, are changed from (lat. 44°32′40′′ 

N., long. 99°27′04′′ W.) to (lat. 44°32′27′′ 

N., long. 99°27′04′′ W.). This minor 

adjustment reflects the current 

information in the FAA’s aeronautical 

database. 

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. Therefore, this regulation: (1) Is 

not a ‘‘significant regulatory action’’ 

under Executive Order 12866; (2) is not 

a ‘‘significant rule’’ under DOT 

Regulatory Policies and Procedures (44 

FR 11034; February 26, 1979); and (3) 

does not warrant preparation of a 

regulatory evaluation as the anticipated 

impact is so minimal. Since this is a 

routine matter that only affects air traffic 

procedures and air navigation, it is 

certified that this rule, when 

promulgated, does not have a significant 

economic impact on a substantial 

number of small entities under the 

criteria of the Regulatory Flexibility Act. 

Environmental Review 

The FAA has determined that this 

action qualifies for categorical exclusion 

under the National Environmental 

Policy Act in accordance with FAA 

Order 1050.1E. ‘‘Environmental 

Impacts: Policies and Procedures,’’ 

paragraph 311a. This airspace action is 

not expected to cause any potentially 

significant environmental impacts, and 

no extraordinary circumstances exist 

that warrant preparation of an 

environmental assessment.
