Background 

On May 30, 2012, Bombardier applied 

for an amendment to type certificate no. 

T00003NY to include the new Model 

BD–700–2A12 and BD–700–2A13 

airplanes. These airplanes are 

derivatives of the Model BD–700 series 

of airplanes currently approved under 

type certificate no. T00003NY, and are 

marketed as the Bombardier Global 7000 

(Model BD–700–2A12) and Global 8000 

(Model BD–700–2A13). These airplanes 

are ultra-long-range, executive-interior 

business jets. 

Type Certification Basis 

Under the provisions of Title 14, Code 

of Federal Regulations (14 CFR) 21.101, 

Bombardier must show that the Model 

BD–700–2A12 and BD–700–2A13 

airplanes meet the applicable provisions 

of the regulations listed in type 

certificate no. T00003NY, or the 

applicable regulations in effect on the 

date of application for the change, 

except for earlier amendments as agreed 

upon by the FAA. 

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 BD–700–2A12 and BD–700– 

2A13 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 BD–700–2A12 

and BD–700–2A13 airplanes must 

comply with the fuel-vent and exhaustemission 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 § 11.38, and they become part of 

the type-certification basis under 

§ 21.101. 

Novel or Unusual Design Features 

The Model BD–700–2A12 and BD– 

700–2A13 airplanes will incorporate the 

following novel or unusual design 

feature: 

Digital systems architecture composed 

of several connected data networks. 

This network architecture and 

configuration may be used for, or 

interfaced with, a diverse set of 

functions, including: 

• Flight-safety-related control, 

communication, and navigation systems 

(airplane-control domain); 


Lhorne on DSK30JT082PROD with RULES
Federal Register / Vol. 81, No. 162 / Monday, August 22, 2016 / Rules and Regulations 56475 

• Operation and administrative 

support (operator-information-services 

domain); and 

• Passenger information and 

entertainment systems (passengerentertainment domain). 

In addition, this digital systems 

architecture will have the capability to 

allow access to or by external network 

sources. 

Discussion 

The Model BD–700–2A12 and BD– 

700–2A13 airplane digital systems 

network architecture is different from 

existing production (and retrofitted) 

airplanes as it allows new kinds of user 

access to previously isolated data 

networks connected to systems that 

perform functions required for the safe 

operation of the airplane. This proposed 

data-network design and integration 

may result in security vulnerabilities 

from intentional or unintentional 

corruption of data and systems critical 

to the safety 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 safetyassessment 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. 

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 Model 

BD–700–2A12 and BD–700–2A13 

airplanes. Should Bombardier 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 the other model as well. 

Conclusion 

This action affects only certain novel 

or unusual design features on 

Bombardier Model BD–700–2A12 and 

BD–700–2A13 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, the FAA 

has determined that prior public notice 

and comment are unnecessary, 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.

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

Inc. Model BD–700–2A12 and BD–700– 

2A13 airplanes. 

1. The applicant must ensure that the 

design provides isolation from, or 

airplane electronic system security 

protection against, access by 

unauthorized sources internal to the 

airplane. The design must prevent 

inadvertent and malicious changes to, 

and all adverse impacts upon, airplane 

equipment, systems, networks, or other 

assets required for safe flight and 

operations. 

2. The applicant must establish 

appropriate procedures to allow the 

operator to ensure that continued 

airworthiness of the airplane is 

maintained, including all post type 

certification modifications that may 

have an impact on the approved 

electronic system security safeguards.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final special conditions; request 

for comments. 

SUMMARY: These special conditions are 

issued for the Beechcraft Corporation 

(Beechcraft) Model 400A airplane. This 

airplane, as modified by Garmin 

International (Garmin), will have a 

novel or unusual design feature when 

compared to the state of technology 

envisioned in the airworthiness 

standards for transport-category 

airplanes. These airplanes will have a 

digital-systems network architecture
