Aircraft Electronic System Security 

Protection From Unauthorized External 

Access 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final special conditions; request 

for comments. 

SUMMARY: These special conditions are 

issued for the ATR–GIE Avions de 

Transport Regional Models ATR42–500 

and ATR72–212A airplanes. These 

airplanes will have novel or unusual 

design features associated with the 

architecture and connectivity 

capabilities of the airplanes’ computer 

systems and networks, which may allow 

access to or by external computer 

systems and networks. Connectivity to, 

or access by, external systems and 

networks 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 November 5, 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 January 22, 2009, ATR–GIE 

Avions de Transport Regional (hereafter 

referred to as ‘‘ATR–GIE’’) applied for a 

change to FAA Type Certificate No. 

A53EU to install a new avionics suite 

that includes connectivity capabilities 

between airplane computer systems and 

networks and external systems and 

networks in their Models ATR42–500 

and ATR72–212A airplanes. Both 

airplanes are two-engine, turbopropeller driven. The Model ATR42– 

500 has a maximum takeoff weight of 

41,005 pounds and an emergency exit 

arrangement to support a maximum of 

60 passengers. The Model ATR72–212A 

has a maximum takeoff weight of 49,603 

pounds and an emergency exit 

arrangement to support a maximum of 

72 passengers. 

Type Certification Basis 

Under the provisions of Title 14, Code 

of Federal Regulations (14 CFR) 21.101, 

ATR–GIE must show that the Models 

ATR42–500 and ATR72–212A, as 

changed, continue to meet the 

applicable provisions of the regulations 

incorporated by reference in Type 

Certificate No. A53EU 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.’’ 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 Models ATR42–500 and ATR72– 

212A 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 features, or should any other 

model already included on the same 

type certificate be modified to 

incorporate the same novel or unusual 

design features, the special conditions 

would also apply to the other model. 

In addition to the applicable 

airworthiness regulations and special 

conditions, the Models ATR42–500 and 

ATR72–212A 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. 

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 Models ATR42–500 and ATR72– 

212A airplanes 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: 

• Flight-safety related control, 

communication, display, monitoring, 

and navigation systems (aircraft control 

functions); 

• Airline business and administrative 

support (airline information services); 

• Passenger information and 

entertainment systems (passenger 

entertainment services); and, 

• The capability to allow access to or 

by systems external to the airplane. 

Discussion 

The Models ATR42–500 and ATR72– 

212A architecture and network 

configuration may allow increased 

connectivity to, or access by, external 

airplane sources, airline operations, and 

maintenance systems to the aircraft 

control functions and airline 

information services. The aircraft 

control functions and airline 

information services perform functions 

required for the safe operation and 

maintenance of the airplane. Previously 

these functions and services 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. 

Applicability 

As discussed above, these special 

conditions are applicable to the ATR– 

GIE Avions de Transport Regional 

Models ATR42–500 and ATR72–212A 

airplanes. Should ATR–GIE 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 

models 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 


erowe on DSK2VPTVN1PROD with 
Federal Register / Vol. 77, No. 219 / Tuesday, November 13, 2012 / Rules and Regulations 67559 

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, 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 ATR–GIE Avions 

de Transport Regional Models ATR42– 

500 and ATR72–212A airplanes. 

1. Airplane Electronic System 

Security Protection from Unauthorized 

External Access. The applicant must 

ensure airplane electronic system 

security protection from access to or by 

unauthorized sources external to the 

airplane, including those possibly 

caused by maintenance activity. 

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 

protect the airplane from all adverse 

impacts on safety, functionality, and 

continued airworthiness. 

3. The applicant must establish 

appropriate procedures to allow the 

operator to ensure that continued 

airworthiness of the aircraft is 

maintained, including all post-typecertification modifications that may 

have an impact on the approved 

electronic system-security safeguards.

ACTION: Final rule. 

SUMMARY: We are revising an existing 

airworthiness directive (AD) for certain 

Bombardier Model CL–600–2B19 

(Regional Jet Series 100 & 440) 

airplanes; all Model CL–600–2C10 

(Regional Jet Series 700, 701, & 702) 

airplanes; all Model CL–600–2D15 

(Regional Jet Series 705) airplanes; and 

all Model CL–600–2D24 (Regional Jet 

Series 900) airplanes. That AD currently 

requires replacing certain water 

accumulator assemblies having a certain 

part installed on the pitot and static 

lines of the air data computer (ADC). 

This new AD corrects an erroneous 

service document number and removes 

the other erroneously cited service 

document from that AD. This new AD 

was prompted by an error that was 

discovered in one service document 

number, and a determination that credit 

for accomplishing actions in another 

erroneously cited service document 

should be removed from that AD. We 

are issuing this AD to prevent pitotstatic tubing from becoming partially or 

completely blocked by water, which 

could result in erroneous airspeed and 

altitude indications and consequent loss 

of control of the airplane. 

DATES: This AD becomes effective 

December 18, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of November 23, 2011 (76 FR 64801, 

October 19, 2011).

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on April 18, 2012 (77 FR 

23169), and proposed to revise AD 

2011–21–07, Amendment 39–16830 (76 

FR 64801, October 19, 2011). That 

NPRM proposed to correct an unsafe 

condition for the specified products. 

Since we issued AD 2011–21–07, 

Amendment 39–16830 (76 FR 64801, 

October 19, 2011), an error was 

discovered in the document number 

specified in paragraph (i), ‘‘Credit for 

Actions Accomplished in Accordance 

with Previous Service Information,’’ of 

that AD. The citation in that paragraph 

should have read ‘‘Bombardier Service 

Bulletin 601R–34–147, Revision A, 

dated November 3, 2009.’’ Additionally, 

we have determined that ‘‘Bombardier 

Service Bulletin 670BA–34–147, dated 

April 1, 2009,’’ was incorrectly included 

in AD 2011–21–07 and should be 

removed from paragraph (i) of that AD. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comment received. 

Request for Credit for Previous Actions 

Air Wisconsin (AWI) requested that 

we revise the NPRM (77 FR 23169, April 

18, 2012) to continue to give credit for 

previous actions for airplanes modified 

using Bombardier Service Bulletin 

601R–34–147, dated April 1, 2009. AWI 

provided the following reasons for its 

request. 

• AWI stated that in the original issue 

of Bombardier Service Bulletin 601R– 

34–147, dated April 1, 2009, for airplane 

serial numbers (S/N) 7003 through 7890, 

this service information called for the 

use of a parts kit that was different from 

the parts kit used for airplane S/Ns 7891 

and subsequent. AWI stated that it 

discovered, during the use of that 

service information, that there was no 

difference between the two groups of 

airplanes. AWI stated that airplane S/Ns 

7891 and subsequent needed to use the 

same parts kit as airplane S/Ns 7003 

through 7890, with the only difference 

being that the kit for airplane S/Ns 7891 

and subsequent lacked two tee fittings, 

part number AS1033W040406, which 

were contained in the kits for airplane 

S/Ns 7003 through 7891. AWI stated 

that, as a result of its discovery,
