AGENCY:
Federal Aviation Administration (FAA), 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) issued by the 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 found the possibility of heating deactivation of Air Data System (ADS) sensors due to its inadequate automatic logic, when ADS/AOA knob is on AUTO position associated with the following messages:
—DC BUS 1 OFF displayed on Crew Alerting System—CAS in conjunction with STBY HTR FAIL (which means loss of power on DC BUS 1); or
—EMER BUS OFF displayed on CAS (which means loss of power on EMERGENCY BUS); or
—ELEC EMERGENCY displayed on CAS (which means Electrical Emergency).
The loss of airplane air data sensors heating may cause ice buildup on their surfaces, which in turn may cause wrong pressure acquisitions resulting in erroneous flight parameters indication to the flight crew. Since this condition may occur in other airplanes of the same type and affects flight safety, an immediate corrective action is required. Thus, sufficient reason exists to request compliance with this AD in the indicated time limit.
This AD requires actions that are intended to address the unsafe condition described in the MCAI.
DATES:
This AD becomes effective December 2, 2009.
We must receive comments on this AD by December 28, 2009.
ADDRESSES:
You may send comments by any of the following methods:

Discussion
The AGÊNCIA NACIONAL DE AVIAÇÃO CIVIL—BRAZIL, which is the aviation authority for Brazil, has issued AD No.: 2009-10-01R1, dated October 16, 2009 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:
It has been found the possibility of heating deactivation of Air Data System (ADS) sensors due to its inadequate automatic logic, when ADS/AOA knob is on AUTO position associated with the following messages:
—DC BUS 1 OFF displayed on Crew Alerting System—CAS in conjunction with STBY HTR FAIL (which means loss of power on DC BUS 1); or
—EMER BUS OFF displayed on CAS (which means loss of power on EMERGENCY BUS); or
—ELEC EMERGENCY displayed on CAS (which means Electrical Emergency).
The loss of airplane air data sensors heating may cause ice buildup on their surfaces, which in turn may cause wrong pressure acquisitions resulting in erroneous flight parameters indication to the flight crew. Since this condition may occur in other airplanes of the same type and affects flight safety, an immediate corrective action is required. Thus, sufficient reason exists to request compliance with this AD in the indicated time limit.
This AD action requires inserting information into the Abnormal Procedures section of the FAA-approved airplane flight manual (AFM). You may obtain further information by examining the MCAI in the AD docket.
FAA's Determination and Requirements of the 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 this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information Start Printed Page 58196referenced above. We are issuing this AD because we evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.
Differences Between This 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 have also required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are described in a separate paragraph of the AD. These requirements take precedence over those copied from the MCAI.
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 the loss of airplane air data sensors heating may cause ice buildup on their surface. This condition may cause wrong pressure acquisitions, resulting in erroneous flight parameters indication to the flight crew. 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-2009-1039; Directorate Identifier 2009-CE-059-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 that this AD:
(1) Is not a “significant regulatory action” under Executive Order 12866;
(2) Is not a “significant rule” under 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.

Effective Date
(a) This airworthiness directive (AD) becomes effective December 2, 2009.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Model EMB-500 airplanes, all serial numbers, certificated in any category.
Subject
(d) Air Transport Association of America (ATA) Code 30: Ice and Rain Protection.
Reason
(e) The mandatory continuing airworthiness information (MCAI) states:
“It has been found the possibility of heating deactivation of Air Data System (ADS) sensors due to its inadequate automatic logic, when ADS/AOA knob is on AUTO position associated with the following messages:
—DC BUS 1 OFF displayed on Crew Alerting System—CAS in conjunction with STBY HTR FAIL (which means loss of power on DC BUS 1); or
—EMER BUS OFF displayed on CAS (which means loss of power on EMERGENCY BUS); or
—ELEC EMERGENCY displayed on CAS (which means Electrical Emergency).
The loss of airplane air data sensors heating may cause ice buildup on their surfaces, which in turn may cause wrong pressure acquisitions resulting in erroneous flight parameters indication to the flight crew. Since this condition may occur in other airplanes of the same type and affects flight safety, an immediate corrective action is required. Thus, sufficient reason exists to request compliance with this AD in the indicated time limit.”
This AD action requires inserting information into the Abnormal Procedures section of the FAA-approved airplane flight manual (AFM).
