AGENCY: Federal Aviation Administration (FAA), Department of

Transportation (DOT).

ACTION: Final rule; request for comments.

SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

It has been determined that due to an intermittent communication between AMS [Air Management System] controller cards and both

Secondary Power Distribution Assemblies (SPDAs) the message ``RECIRC

SMK DET FAIL'' is displayed in the Engine Indication and Crew

Alerting System (EICAS). This communication failure could result in loss of automatic activation of engine inlet ice protection system when in ice condition. In this situation the caution messages ``A-I

Eng 1 Fail'' and ``A-I Eng 2 Fail'' will be displayed and if the flight crews do not follow the associated procedures ice may accrete in the engines inlet and cause a dual engine shut down.

* * * * *

This AD requires actions that are intended to address the unsafe condition described in the MCAI.

DATES: This AD becomes effective April 9, 2010.

We must receive comments on this AD by May 10, 2010.

SUPPLEMENTARY INFORMATION:

Discussion

The Ag[ecirc]ncia Nacional de Avia[ccedil][atilde]o Civil (ANAC), which is the aviation authority for Brazil, has issued Brazilian

Airworthiness Directives 2010-01-01 and 2010-01-02, both effective

January 31, 2010 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states:

It has been determined that due to an intermittent communication between AMS [Air Management System] controller cards and both

Secondary Power Distribution Assemblies (SPDAs) the message ``RECIRC

SMK DET FAIL'' is displayed in the Engine Indication and Crew

Alerting System (EICAS). This communication failure could result in loss of automatic activation of engine inlet ice protection system when in ice condition. In this situation the caution messages ``A-I

Eng 1 Fail'' and ``A-I Eng 2 Fail'' will be displayed and if the flight crews do not follow the associated procedures ice may accrete in the engines inlet and cause a dual engine shut down.

* * * * *

The required action includes revising the Limitations section of the airplane flight manual to prohibit dispatch with message ``RECIRC SMK

DET FAIL'' displayed on the ground unless troubleshooting action confirms the message has not been triggered due to a failure of an AMS controller card. You may obtain further information by examining the

MCAI in the AD docket.

FAA's Determination and Requirements of This AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.

Differences Between the AD and the MCAI or Service Information

We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the

AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information.

We might also have required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the AD.

FAA's Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because an intermittent communication failure between AMS controller cards and both SPDAs could result in the loss of automatic activation of the engine inlet ice protection system when in icing conditions. In this situation, the caution messages ``A-I Eng 1 Fail'' and ``A-I Eng 2

Fail'' will be displayed. If the flight crews do not follow the associated procedures, ice may accrete in the engines' inlet and cause a dual engine shut down. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2010-0274; Directorate

Identifier 2010-NM-055-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.

We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. ``Subtitle VII: Aviation

Programs,'' describes in more detail the scope of the Agency's authority.

We are issuing this rulemaking under the authority described in

``Subtitle VII, Part A, Subpart III, Section 44701: General requirements.'' Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.

Regulatory Findings

We determined that this AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify this AD: 1. Is not a ``significant regulatory action'' under Executive Order 12866;

Page 14335

2. Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and 3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Safety.

Adoption of the Amendment 0

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new AD: 2010-07-04 Empresa Brasileira de Aeronautica S.A. (EMBRAER):

Amendment 39-16248. Docket No. FAA-2010-0274; Directorate Identifier 2010-NM-055-AD.

Effective Date

(a) This airworthiness directive (AD) becomes effective April 9, 2010.

Affected ADs

(b) None.

Applicability

(c) This AD applies to Empresa Brasileira de Aeronautica S.A.

(EMBRAER) Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU airplanes; Model ERJ 170-200 LR, -200 SU, and -200 STD airplanes;

Reason

(e) The mandatory continued airworthiness information (MCAI) states:

It has been determined that due to an intermittent communication between AMS [Air Management System] controller cards and both

Secondary Power Distribution Assemblies (SPDAs) the message ``RECIRC

SMK DET FAIL'' is displayed in the Engine Indication and Crew

Alerting System (EICAS). This communication failure could result in loss of automatic activation of engine inlet ice protection system when in ice condition. In this situation the caution messages ``A-I

Eng 1 Fail'' and ``A-I Eng 2 Fail'' will be displayed and if the flight crews do not follow the associated procedures ice may accrete in the engines inlet and cause a dual engine shut down.

* * * * *

The required action includes revising the Limitations section of the airplane flight manual to prohibit dispatch with message ``RECIRC

SMK DET FAIL'' displayed on the ground unless troubleshooting action confirms the message has not been triggered due to a failure of an

AMS controller card.

Compliance

(f) You are responsible for having the actions required by this

AD performed within the compliance times specified, unless the actions have already been done.

Actions

(g) Within 10 days after the effective date of this AD, revise the Limitations section of the airplane flight manual (AFM) to include the following statement. This may be done by inserting a copy of this AD in the AFM.

``Dispatch with the message `RECIRC SMK DET FAIL' displayed on the ground is prohibited unless troubleshooting action confirms the message has not been triggered due to a failure of an AMS controller card.''

Note 1: When a statement identical to that in paragraph (g) of this AD has been included in the general revisions of the AFM, the general revisions may be inserted into the AFM, and the copy of this

AD may be removed from the AFM.

Note 2: The limitation and procedure specified in paragraph (g) of this AD is an interim solution until a final action is identified, at which time the FAA might consider further rulemaking.

FAA AD Differences

Note 3: This AD differs from the MCAI and/or service information as follows: No differences.
