Rule

Airworthiness Directives; Sicma Aero Seat Passenger Seat Assemblies, Installed on, But Not Limited to, ATR-GIE Avions de Transport Régional Airplanes

Action

Final Rule; Request For Comments.

Summary

We are superseding an existing airworthiness directive (AD) for certain Sicma Aero Seat Model 9401, 9402, 9404, 9505, 9406, 9407, 9408, and 9409 series passenger seat assemblies, installed on, but not limited to, ATR—GIE Avions de Transport Régional Model ATR42 and ATR72 airplanes. That AD currently requires repetitive detailed inspections for cracking of the central and lateral spreaders of the affected seats, and repair or replacement of the spreader if necessary. This AD was prompted by a determination that the existing AD included Model 9505 series passenger seat assemblies in the applicability instead of Model 9405 series passenger seat assemblies. We are issuing this AD to detect and correct cracking of the central and lateral spreaders, which could lead to further cracking of the seat spreaders, causing injury to passengers or crew members during heavy turbulence in flight or in the event of an emergency landing.

SUPPLEMENTARY INFORMATION: Back to Top

On October 20, 2011, we issued AD 2011-23-06, Amendment 39-16857 (76 FR 68304, November 4, 2011). That AD required actions intended to address an unsafe condition on Sicma Aero Seat Model 9401, 9402, 9404, 9505, 9406, 9407, 9408, and 9409 series passenger seat assemblies, installed on, but not limited to, ATR—GIE Avions de Transport Régional Model ATR42 and ATR72 airplanes.

Since we issued AD 2011-23-06, Amendment 39-16857 (76 FR 68304, November 4, 2011), we have determined that the applicability of that AD included Model 9505 series passenger seat assemblies in the applicability instead of Model 9405 series passenger seat assemblies. We have revised the applicability of this AD accordingly and added new paragraph (h) for Sicma Aero Seat Model 9405 series passenger seat assemblies.

Change to Existing AD Back to Top

Since we issued AD 2011-23-06, Amendment 39-16857 (76 FR 68304, November 4, 2011), the AD format has been revised, and certain paragraphs have been rearranged. As a result, the corresponding paragraph identifiers have changed in this AD, as listed in the following table:

FAA's Determination and Requirements of This AD Back to Top

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.

There are no products of this type currently registered in the United States. However, this rule is necessary to ensure that the described unsafe condition is addressed if any of these products are placed on the U.S. Register in the future.

FAA's Determination of the Effective Date Back to Top

Since there are currently no domestic operators of this product, notice and opportunity for public comment before issuing this AD are unnecessary.

Comments Invited Back to Top

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-2012-0334; Directorate Identifier 2012-NM-001-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 Back to Top

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 Back to Top

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 the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);

3. Will not affect intrastate aviation in Alaska; and

4. 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 Back to Top
