54574 Federal Register / Vol. 79, No. 177 / Friday, September 12, 2014 / Rules and Regulations 

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, which is 

imminent, the FAA has determined that 

prior public notice and comment are 

unnecessary and impracticable, and 

good cause exists for adopting these 

special conditions upon issuance. 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.

ACTION: Final special conditions; request 

for comments. 

SUMMARY: These special conditions are 

issued for the Bombardier Aerospace 

Models BD–500–1A10 and BD–500– 

1A11 series airplanes. These airplanes 

will have novel or unusual design 

features, specifically, digital systems 

architecture composed of several 

connected networks that may allow 

access to or by external computer 

systems and networks and may result in 

security vulnerabilities to the airplanes’ 

systems. The applicable airworthiness 

regulations do not contain adequate or 

appropriate safety standards for these 

design features. 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. 

DATES: The effective date of these 

special conditions is September 12, 

2014. We must receive your comments 

by October 27, 2014.

SUPPLEMENTARY INFORMATION: The FAA 

has determined that notice of, and 

opportunity for prior public comment 

on, these special conditions is 

impracticable because these procedures 

would significantly delay issuance of 

the design approval and thus delivery of 

the affected aircraft. 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 December 10, 2009, Bombardier 

Aerospace applied for a type certificate 

for their new Models BD–500–1A10 and 

mstockstill on DSK4VPTVN1PROD with RULES

Federal Register / Vol. 79, No. 177 / Friday, September 12, 2014 / Rules and Regulations 54575 

BD–500–1A11 series airplanes (hereafter 

collectively referred to as ‘‘CSeries’’). 

The CSeries airplanes are swept-wing 

monoplanes with an aluminum alloy 

fuselage sized for 5-abreast seating. 

Passenger capacity is designated as 110 

for the Model BD–500–1A10 and 125 for 

the Model BD–500–1A11. Maximum 

takeoff weight is 131,000 pounds for the 

Model BD–500–1A10 and 144,000 

pounds for the Model BD–500–1A11. 

Type Certification Basis 

Under the provisions of Title 14, Code 

of Federal Regulations (14 CFR) 21.17, 

Bombardier Aerospace must show that 

the CSeries airplanes meet the 

applicable provisions of 14 CFR 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 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, the special 

conditions would also apply to the other 

model. 

In addition to the applicable 

airworthiness regulations and special 

conditions, the CSeries 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, and the 

FAA must issue a finding of regulatory 

adequacy under section 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 CSeries will incorporate the 

following novel or unusual design 

features: Digital systems architecture 

composed of several connected 

networks. This network architecture and 

network configuration may be used for 

or interfaced with a diverse set of 

functions, including: 

• Flight safety related control, 

communication, and navigation systems 

(aircraft control domain); 

• Operator business and 

administrative support (operator 

information domain); and 

• Passenger information and 

entertainment systems (passenger 

entertainment domain), and will have 

the capability to allow access to or by 

external network sources. 

Discussion 

The CSeries digital systems network 

architecture is novel or unusual for 

commercial transport airplanes as it 

allows connection to airplane electronic 

systems and networks, and access from 

aircraft external sources (e.g., operator 

networks, wireless devices, Internet 

connectivity, service provider satellite 

communications, electronic flight bags, 

etc.), to the previously isolated airplane 

electronic assets. Airplane electronic 

assets include electronic equipment and 

systems, instruments, networks, servers, 

software and electronic components, 

field-loadable software and hardware 

applications, databases, etc. This 

proposed design may result in network 

security vulnerabilities from intentional 

or unintentional corruption of data and 

systems required for the safety, 

operations, and maintenance of the 

airplane. 

The existing regulations and guidance 

material did not anticipate these types 

of system architectures or access to 

airplane systems. Furthermore, 14 CFR 

regulations and current system safety 

assessment policy and techniques do 

not address potential security 

vulnerabilities that could be caused by 

unauthorized access to airplane data 

busses and servers. Therefore, these 

special conditions are issued to ensure 

that the security, integrity, and 

availability of airplane systems are not 

compromised by certain wired or 

wireless electronic connections between 

airplane data busses and networks. 

Applicability 

As discussed above, these special 

conditions are applicable to the Model 

No. BD–500–1A10 and BD–500–1A11. 

Should Bombardier Aerospace 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 special conditions 

would apply to that model as well. 

Conclusion 

This action affects only certain novel 

or unusual design features on two 

model series of 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, which is 

imminent, the FAA has determined that 

prior public notice and comment are 

unnecessary and impracticable, and 

good cause exists for adopting these 

special conditions upon issuance. 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.
