**[Docket No. FAA–2012–0774; Directorate Identifier 2010–SW–057–AD]** 

**RIN 2120–AA64**

**Airworthiness Directives; Eurocopter France Helicopters** 

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

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

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS350BA helicopters with certain AERAZUR emergency flotation gear container assemblies installed. This proposed AD would require replacing each affected emergency flotation gear container assembly (container assembly) at specified time limits based on the date of manufacture. This proposed AD is prompted by a recognition that container assemblies with an intended operating limitation of 10 years may not have been replaced because the limit is no longer recorded in the Maintenance Program. The proposed actions are intended to prevent failure of the emergency container assembly due to age and subsequent damage to the helicopter and injury to the occupants after an emergency water landing.

**DATES :**  We must receive comments on this proposed AD by September 24,
2012.

**ADDRESSES :**  You may send comments by any of the following methods:

• Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

• Fax: 202–493–2251.

• Mail: U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC 20590.

• Hand Delivery: U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC 20590, between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

Examining the AD Docket: You may examine the AD docket on the Internet
at http://www.regulations.gov or in person at the Docket Operations Office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays.

We will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. We may change this proposal in light of the comments we receive.

Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued AD No. 2008–0189, dated October 10, 2008, to correct an unsafe condition for the Eurocopter Model AS350BA helicopters with certain AERAZUR emergency flotation gear installed. EASA advises that the container assemblies have an operating life limit of 10 years from the date of manufacture. The EASA AD states that ‘‘as of June 2006, this limit is no longer recorded in the Maintenance Program; therefore, after June 2006, container assemblies having already exceeded the 10-year limit could have not been replaced yet.’’ The EASA AD also states that ‘‘floating performance of a helicopter may prove to be insufficient in the event of ditching, in case of failure of a container assembly being operated beyond its operating time limit.’’

FAA’s Determination

This helicopter model is manufactured in France and is type certificated for operation in the United States under the provisions of 14 CFR 21.29 and the applicable bilateral agreement. Pursuant to the applicable bilateral agreement, EASA has kept the FAA informed of the situation described above.

We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of the same type design.

Related Service Information

Eurocopter has issued Alert Service Bulletin No. 25.01.02, dated September 24, 2008 (EASB), which specifies certain times measured from the date of manufacture to replace the container assemblies. EASA classified this EASB as mandatory and issued AD No. 2008– 0189, dated October 10, 2008, to ensure the continued airworthiness of these helicopters. Proposed AD Requirements

This proposed AD would require determining the manufacturing date of each part-numbered container assembly, and depending on the date, replacing


### 43735 Federal Register / Vol. 77, No. 144 / Thursday, July 26, 2012 / Proposed Rules

the container assembly with an airworthy container assembly at specified times. Differences Between This Proposed AD and the EASA AD

We do not allow return of the container assemblies to the manufacturer for an inspection and extension of the life limit. Costs of Compliance

We estimate that this proposed AD would affect 85 helicopters of U.S. registry. We estimate that operators may incur the following costs in order to comply with this AD.

• It would take minimal time to determine the manufacturing date of the container and about 1 ⁄ 2 work hour per helicopter to replace the container assemblies at an average labor rate of $85 per work hour.

• Required parts would cost about $21,775 for the left container assembly and $26,690 for the right container assembly per helicopter.

Based on these figures, we estimate the total cost impact of the proposed AD on U.S. operators to be $485,075, assuming 10 helicopters require replacement of the right and left container assemblies. 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, 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 to the extent that it justifies making a regulatory distinction; 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 an economic 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
