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

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A300 B4–601, B4–603, and B4–605R airplanes, Model A300 F4–605R airplanes, Model A300 C4– 605R Variant F airplanes, and Model A310–204 and –304 airplanes, powered by General Electric (GE) CF6–80C2 series engines. This proposed AD wasprompted by reports of two singleengine flame-out events during inclement weather. This proposed AD would require installing a shunt of therotary selector (introducing an autorelight function). We are proposing this AD to prevent a long engine restart sequence after a non-selection of continuous re-light by the crew and a flame-out event of both engines, which could result in reduced controllability of the airplane, especially at low altitude.

**DATES :**  We must receive comments on this proposed AD by August 2, 2012.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2011–0113, dated June 17, 2011 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states:

Two single [engine] flame out events attributed to inclement weather occurred on Wide Body (WB) aeroplanes powered with GE CF6–80C2 engines.

On WB aeroplanes, no auto-relight function is embodied. To avoid long engine restart sequence after a non selection of continuous relight by the crew and a flame out event of both engines, resulting in strongly reduced control of the aeroplane especially at low altitude, the manufacturer Airbus designed a modification by introducing auto-relight function for aeroplanes powered by GE CF6–80C2 engines.

For the reason described above, this EASA AD requires the installation on the aeroplane of an auto-relight function [installing a shunt of the rotary selector] as a precaution and to increase restart capability without crew action. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Airbus has issued Mandatory Service Bulletin A310–74–2003, Revision 02, including Appendix 1, dated February 9, 2012 (for Model A310–204 and –304 airplanes); and Mandatory Service Bulletin A300–74–6003, Revision 02, including Appendix 1, dated February 9, 2012 (for Model A300 B4–601, B4– 603, and B4–605R airplanes, Model A300 F4–605R airplanes, and Model A300 C4–605R Variant F airplanes). The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This Proposed 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 proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance

Based on the service information, we estimate that this proposed AD would affect about 47 products of U.S. registry. We also estimate that it would take about 80 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $12,500 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $907,100, or $19,300 per product. 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed regulation:

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 proposed AD and placed it in the AD docket. List of Subjects in 14 CFR Part 39
