facsimile 425–227–1149.

**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. Bothairplanes 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


### 67559 Federal Register / Vol. 77, No. 219 / Tuesday, November 13, 2012 / Rules and Regulations

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.

List of Subjects in 14 CFR Part 25

**RIN 2120–AA64**

**Airworthiness Directives; Bombardier, Inc. Airplanes** 

**AGENCY :**  Federal Aviation Administration (FAA), Department of Transportation (DOT).

**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. Weare 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).

**ADDRESSES :**  You may examine the AD
docket on the Internet at http:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC.

**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,
