### 11072 Federal Register / Vol. 75, No. 46 / Wednesday, March 10, 2010 / Proposed Rules

1 To view the glossary on the Internet, go to ( http://www.ippc.int/IPP/En/default.jsp ) and click on the ‘‘Adopted ISPMs ’’ link under the ‘‘ Standards (ISPMs) ’’ heading. apples are effective and appropriate to manage pest risks associated with all varieties of M

. domestica apples from Japan. Therefore, we propose to amend the regulations to allow the entry of all varieties of M

. domestica apples from approved areas in Japan to the United States under the provisions of § 319.56-
27.

Specifically, we would revise the introductory text of § 319.56-27 to indicate that any variety of M

. domestica apples may be imported from Japan under the conditions in § 319.56- 27. We would also remove specific references to Fuji variety apples in the section heading and the regulatory text and instead refer generally to apples. We would also revise the term ‘‘national plant protection agency’’ to read

‘‘national plant protection organization, ’’ to make the regulations consistent with the International Glossary of Phytosanitary Terms (International Standards for Phytosanitary Measures No. 5). 1 Executive Order 12866 and Regulatory Flexibility Act

This proposed rule has been determined to be not significant for the purposes of Executive Order 12866 and, therefore, has not been reviewed by the Office of Management and Budget.

For this proposed rule we have prepared an economic analysis. The economic analysis supports our conclusion that allowing imports of all varieties of M

. domestica apples from Japan into the United States would have minimal economic impact on U.S. entities, large or small. Although the Fuji apple is the most common variety grown in Japan, it constituted only 0.1 percent of U.S. apple imports in 2008. Allowing entry of other M

. domestica varieties is expected to change the quantity of apple imports from Japan only minimally. The wide price differential between apples grown in Japan and in the United States suggests that apples imported from Japan are not a close substitute for the principal U.S.- grown apple varieties. Under these circumstances, the Administrator of the Animal and Plant Health Inspection Service has determined that this action would not have a significant economic impact on a substantial number of small entities.

The full economic analysis may be viewed on the Regulations.gov Web site or in our reading room. (Instructions for accessing Regulations.gov and information on the location and hours of the reading room are provided under the heading **ADDRESSES** at the beginning of this proposed rule.) In addition, copies may be obtained by calling or writing to the individual listed under **FOR FURTHER**
**INFORMATION CONTACT**

. Executive Order 12988

This proposed rule would allow all varieties of M

. domestica apples to be imported into the United States from Japan. If this proposed rule is adopted, State and local laws and regulations regarding all varieties of M

. domestica apples imported under this rule would be preempted while the fruit is in foreign commerce. Fresh fruits are generally imported for immediate distribution and sale to the consuming public and would remain in foreign commerce until sold to the ultimate consumer. The question of when foreign commerce ceases in other cases must be addressed on a case-by-case basis. If this proposed rule is adopted, no retroactive effect will be given to this rule, and this rule will not require administrative proceedings before parties may file suit in court challenging this rule. Paperwork Reduction Act

This proposed rule contains no new information collection or recordkeeping requirements under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et
seq .). List of Subjects in 7 CFR Part 319

Coffee, Cotton, Fruits, Imports, Logs, Nursery stock, Plant diseases and pests, Quarantine, Reporting and recordkeeping requirements, Rice, Vegetables.

Accordingly, we propose to amend 7 CFR part 319 as follows:

**PART 319—FOREIGN QUARANTINE NOTICES**

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

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

**SUMMARY :**  The FAA proposes to supersede an existing airworthiness directive (AD) for certain Turbomeca Arriel 1B, 1D, 1D1, and 1S1 turboshaft engines. That AD requires initial and repetitive relative position checks of the gas generator 2nd stage turbine blades on Turbomeca Arriel 1B (that incorporate Turbomeca Modification (mod) TU 148), Arriel 1D, 1D1, and 1S1 turboshaft engines that do not incorporate mod TU 347. That AD also requires initial and repetitive replacements of 2nd stage turbines on Arriel 1B, 1D, and 1D1 engines. This proposed AD would require lowering the repetitive threshold for relative position checks on Arriel 1B engines. This proposed AD would also require lowering the initial and repetitive thresholds for replacement of 2nd stage turbines on Arriel 1B, 1D, and 1D1 engines. This proposed AD results from reports of new cases of failures of 2nd stage turbine blades since we issued AD 2008–07–01. We are proposing this AD to prevent the failure of 2nd stage turbine blades, which could result in an uncommanded in-flight engine

Discussion

On March 17, 2008, the FAA issued AD 2008–07–01, Amendment 39–15442 (73 FR 15866, March 26, 2008). That AD requires initial and repetitive relative position checks of the gas generator 2nd stage turbine blades on Turbomeca Arriel 1B (that incorporate mod TU 148), 1D, 1D1, and 1S1 turboshaft engines that do not incorporate mod TU 347. That AD also requires initial and repetitive replacements of 2nd stage turbines on 1B, 1D, and 1D1 engines. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, recently notified us that an unsafe condition likely exists on Turbomeca Arriel 1B, 1D, 1D1, and 1S1 turboshaft engines.

Since AD 2008–07–01 Was Issued

Since AD 2008–07–01 was issued, EASA reports that in engines that do not incorporate mod TU 347, new cases of gas generator 2nd stage turbine blade release have occurred, at lower blade service lives than previously reported. EASA issued AD 2009–0236, dated October 29, 2009, to optimize the 2nd stage turbine blade life limit and the replacement allowances for turbines currently in service in Europe, based on parts availability while keeping the risk level within acceptable limits.

Relevant Service Information

We have reviewed and approved the technical contents of Turbomeca Mandatory Service Bulletin (MSB) No. A292 72 0807, Version E, dated October 29, 2009, that describes procedures for the relative position check of 2nd stage turbine blades, and replacement of 2nd stage turbines that do not incorporate mod TU 347, with inspected 2nd stage turbines, or with 2nd stage turbines that incorporate mod TU 347, on Arriel 1B, 1D, and 1D1 engines. We have also reviewed and approved the technical contents of Turbomeca MSB No. A292 72 0810, Version C, dated July 24, 2009, that describes procedures for the relative position check of 2nd stage turbine blades on Arriel 1S1 engines. EASA classified these MSBs as mandatory and issued AD 2009–0236, dated October 29, 2009, to ensure the airworthiness of these Turbomeca Arriel engines in Europe. Bilateral Agreement Information

This engine model is manufactured in France, and is type certificated for operation in the United States under the provisions of Section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Under this bilateral airworthiness agreement, EASA kept us informed of the situation described above. We have examined the findings of the EASA, reviewed all available information, and determined that AD action is necessary for products of this type design that are certificated for operation in the United States. FAA’s Determination and Requirements of the Proposed AD

We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other products of this same type design. We are proposing this AD supersedure, which would require lowering the repetitive threshold for relative position checks on Arriel 1B engines. This proposed AD would also require lowering the initial and repetitive thresholds for replacement of 2nd stage turbines on Arriel 1B, 1D, and 1D1 engines. The proposed AD would require that you do these actions using the service information described previously. Costs of Compliance

Based on the service information, we estimate that this proposed AD would affect about 587 Turbomeca Arriel 1B, 1D, 1D1, and 1S1 turboshaft engines installed on products of U.S. registry. We also estimate that it would take about 2 work-hours per engine to perform one inspection, and about 40 work-hours per engine to replace the gas turbine discs and blades. The average labor rate is $85 per work-hour. Required parts would cost about $54,000 per engine. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $33,793,590. Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I,


### 11074 Federal Register / Vol. 75, No. 46 / Wednesday, March 10, 2010 / Proposed Rules

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 have 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 that the proposed 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); and

3. Would 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. See the **ADDRESSES** section for a location to examine the regulatory evaluation.

**Enhancing Airline Passenger Protections: Response to Requests To**  **Extend Compliance Date**

**AGENCY :**  Office of the Secretary (OST), Department of Transportation (DOT).

**ACTION :**  Notice of proposed rulemaking. **SUMMARY :**  The Department of Transportation is proposing to extend by 45 days, or until June 14, 2010, the compliance date of the provision in its final rule entitled ‘‘Enhancing Airline Passenger Protections, ’’ published December 30, 2009, and effective April 29, 2010, that requires airlines to publish flight delay information on their Web sites. This proposal is in response to the petition of the Air Transport Association of America (ATA), the Regional Airline Association (RAA) and the Air Carrier Association of America (ACAA) for an additional 90 days time for airlines to comply with the requirement to display flight delay data on Web sites in view of the extensive changes to carriers’ reporting systems that are necessitated by the rule and their contention that completion of these tasks is not possible by April 29, 2010, the current effective date of the requirement. The Department acknowledges that additional time to comply with the posting of flight delay information on the carriers’ Web sites may be warranted to ensure the posting of complete and accurate information but is not persuaded that the full 90 days requested by the carrier associations is needed. Therefore, this NPRM proposes to extend the compliance date for the provision in question for an additional 45 days, from April 29, 2010, to June 14, 2010.

**DATES :**  Comments on amending the final rule published December 30, 2009, at 74 FR 68983, effective April 29, 2010, should be filed by March 25, 2010.
