Docket No. FAA-2011-1141
Special Conditions No. 25-451-SC
https://www.federalregister.gov/d/2011-27196 https://www.federalregister.gov/d/2011-27196
These special conditions are issued for the Gulfstream Aerospace Corporation Model GIV-X airplane. This airplane will have novel or unusual design features associated with the architecture and connectivity capabilities of the airplane's computer systems and networks, which may allow access by external computer systems and networks. Connectivity by external systems and networks may result in security vulnerabilities to the airplane's 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.

On April 21, 2011, Gulfstream Aerospace Corporation (hereafter referred to as “Gulfstream”) applied for a supplemental type certificate to install a new interior design configuration in the Gulfstream Model GIV-X passenger airplane. The Gulfstream Model GIV-X is a two-engine jet transport airplane with a maximum takeoff weight of 47,600 pounds and an interior configuration for a maximum of 19 passengers.
Under the provisions of Title 14, Code of Federal Regulations (14 CFR) 21.101, Gulfstream must show that the Gulfstream Model GIV-X airplane (hereafter referred to as the “GIV-X”), as changed, continues to meet the applicable provisions of the regulations incorporated by reference in Type Certificate No. A12EA or the applicable regulations in effect on the date of application for the change. The regulations incorporated by reference in the type certificate are commonly referred to as the “original type certification basis.” The regulations incorporated by reference in Type Certificate No. A12EA are as follows:
14 CFR part 25, effective February 1, 1965, including Amendments 25-1 through 25-56, except for the following sections which are limited to showing compliance with the amendments indicated: Part 25 effective February 1, 1965, §§ 25.109, 25.571, and 25.813; part 25 Amendment 25-22, § 25.571; and part 25 Amendment 25-15, § 25.807(c)(2). 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 GIV-X 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 applicant apply for a supplemental type certificate to modify any other model included on the same type certificate to incorporate 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 GIV-X 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.
The GIV-X will incorporate the following novel or unusual design features: digital systems architecture 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 domain);
2. Airline business and administrative support (airline information domain);
3. Passenger information and entertainment systems (passenger entertainment domain), and;
The GIV-X architecture and network configuration may allow increased connectivity to, and access by, external airplane sources, airline operations, and maintenance systems to the aircraft control domain and airline information domain. The aircraft control domain and airline information domain perform functions required for the safe operation and maintenance of the airplane. Previously these domains had very limited connectivity with external sources. The architecture and network configuration may allow the exploitation of network security vulnerabilities resulting in intentional or unintentional destruction, disruption, degradation, or exploitation of data, systems, and networks critical to the safety and maintenance of the airplane. The existing regulations and guidance material did not anticipate these types of airplane 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 systems, data buses, and servers. Therefore, these special conditions are 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.
As discussed above, these special conditions are applicable to the Gulfstream Model GIV-X. Should Gulfstream apply at a later date for a supplemental type certificate to modify any other model included on the Type Certificate No. A12EA to incorporate the same novel or unusual design features, these special conditions would apply to that model as well.
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 Model GIV-X airplanes.
2. The applicant must ensure that electronic system security threats are identified and assessed, and that effective electronic system security protection strategies are implemented to Start Printed Page 65105protect the airplane from all adverse impacts on safety, functionality, and continued airworthiness.
