Discussion
EASA, which is the Technical Agent for the Member States of the European Community, has issued EASA Emergency AD No. 2007-0159-E, dated June 6, 2007, to correct an unsafe condition for Eurocopter Model EC 155B and EC155B1 helicopters.
This AD requires actions that are intended to detect a short circuit in a hoist connector and prevent a fire in the aircraft. You may obtain further information by examining the MCAI and any related service information in the AD docket.
Related Service Information
Eurocopter has issued Emergency Alert Service Bulletin No. 25A085, dated June 1, 2007. The actions described in the MCAI are intended to correct the same unsafe condition as that identified in the service information.
FAA's Evaluation and Unsafe Condition Determination
This product has been approved by the aviation authority of France, and is approved for operation in the United States. Pursuant to our bilateral agreement withFrance, their Technical Agent has notified us of the unsafe condition described in the MCAI. We are issuing this AD because we evaluated all information provided by EASA on behalf of France and determined the unsafe condition exists and is likely to exist or develop on other helicopters of this same type design.
Differences Between This AD and the MCAI
We have used a compliance time of 1 month rather than 3 months because of the serious consequences of an undetected short circuit and potential aircraft fire.
Costs of Compliance
We estimate that this AD will affect 1 helicopter of U.S. registry. We also estimate that it will take about 3 work-hours to comply with the basic requirements of this AD. The average labor rate is $80 per work-hour. Required parts will cost about $500 per helicopter. Based on these figures, we estimate the cost of this AD on U.S. operators will be $740.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of this AD. We find that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because a wiring short circuit near the hoist cut-off connector caused the paint on the cooler support cowling to catch on fire. Therefore, we have 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. However, we invite you to send us any written data, views, or arguments concerning this AD. Send your comments to an address listed under the ADDRESSES section of this AD. Include "Docket No. FAA-2009- 0195; Directorate Identifier 2007-SW-34-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 product(s) 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.
Therefore, I certify 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); 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 an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.
