critical systems and data networks. 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 June 7, 2012. We 

must receive your comments by August 

13, 2012.

SUPPLEMENTARY INFORMATION: The FAA 

has determined that notice of, and 

opportunity for prior public comment 

on, these special conditions are 

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 issuance. 

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 March 30, 2006, Gulfstream 

Aerospace LP (hereafter referred to as 

‘‘GALP’’) applied for a type certificate 

for their new Model Gulfstream G280 

(hereafter referred to as ‘‘Model G280’’) 

airplane. The Model G280 is a twoengine jet transport airplane with a 

maximum takeoff weight of 39,600 

pounds and an emergency exit 

arrangement to support a maximum of 

19 passengers. Although the Model 

G280 design includes occupancy 

provisions for pilot and copilot only (no 

passengers), GALP requested issuance of 

these special conditions to support 

efficient design and certification of 

passenger cabin interiors through the 

supplemental type certification process. 

Type Certification Basis 

Under the provisions of Title 14, Code 

of Federal Regulations (14 CFR) 21.17, 

GALP must show that the Model G280 

meets the applicable provisions of part 

25, as amended by Amendments 25–1 

through 25–120, thereto, and 

Amendment 25–122. In addition, the 

certification basis includes certain 

special conditions, exemptions, and 

equivalent safety findings 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 G280 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, the special conditions 

would also apply to the other model. 

In addition to the applicable 

airworthiness regulations and special 

conditions, the Model G280 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 § 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 Model G280 will incorporate the 

following novel or unusual design 

features: Digital systems architecture

38468 Federal Register / Vol. 77, No. 125 / Thursday, June 28, 2012 / Rules and Regulations 

composed of several connected 

networks. The proposed architecture 

and network configuration may be used 

for, or interfaced with, a diverse set of 

functions, including: 

1. Flight-safety related control, 

communication, and navigation systems 

(aircraft control functions); 

2. Airline business and administrative 

support (airline information services), 

and; 

3. Passenger information and 

entertainment systems (passenger 

entertainment services). 

Discussion 

The Model G280 integrated network 

configuration may allow increased 

connectivity with external network 

sources and will have more 

interconnected networks and systems, 

such as passenger entertainment and 

information services, than previous 

GALP airplane models. This may allow 

the exploitation of network security 

vulnerabilities and increased risks 

potentially resulting in unsafe 

conditions for the airplane and its 

occupants. This potential exploitation of 

security vulnerabilities may result in 

intentional or unintentional destruction, 

disruption, degradation, or exploitation 

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. Furthermore, 14 

CFR regulations and current system 

safety assessment policy and techniques 

do not address potential security 

vulnerabilities which could be exploited 

by unauthorized access to airplane 

networks and servers. Therefore, these 

special conditions are being issued to 

ensure that the security (i.e., 

confidentiality, integrity, and 

availability) of airplane systems is not 

compromised by unauthorized wired or 

wireless electronic connections between 

airplane systems and the passenger 

entertainment services. 

Applicability 

As discussed above, these special 

conditions are applicable to the Model 

G280. Should GALP 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 one model 

of airplane. 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.

The Special Conditions 

Accordingly, pursuant to the 

authority delegated to me by the 

Administrator, the following special 

conditions are issued as part of the type 

certification basis for Gulfstream 

Aerospace LP, Model Gulfstream G280 

airplanes. 

1. Isolation or Aircraft Electronic 

System Security Protection from 

Unauthorized Internal Access. 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 aircraft is 

maintained, including all post type 

certification modifications that may 

have an impact on the approved 

electronic system security safeguards.

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Bombardier, Inc. Model CL–600–2B19 

(Regional Jet Series 100 & 440) 

airplanes. This AD was prompted by a 

report of a ground fire which was fed by 

oxygen escaping from a damaged third 

crew person oxygen line and had started 

in the vicinity of an electrical panel. 

This AD requires replacing and 

changing the routing of the flexible 

oxygen hose of the third crew person 

oxygen line and modifying the entrance 

compartment assembly. We are issuing 

this AD to prevent the possibility of 

damage to the third crew person oxygen 

line and of an oxygen-fed fire in the 

airplane. 

DATES: This AD becomes effective 

August 2, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of August 2, 2012.
