Start Preamble

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Final rule; request for comments.

SUMMARY:

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:

Defective inlet self-seal valves have been identified. Detachment of a seal inside the valve could result in partial or complete blockage of the burner supply.

On a hopper balloon this failure would result in an uncontrolled descent. In some circumstances this could result in serious injury.

This AD requires actions that are intended to address the unsafe condition described in the MCAI.

DATES:

This AD becomes effective March 25, 2008.

On March 25, 2008, the Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD.

We must receive comments on this AD by April 4, 2008.

SUPPLEMENTARY INFORMATION:

Discussion

The Civil Aviation Authority, which is the aviation authority for the United Kingdom, has issued AD No: G-2008-0002, dated January 14, 2008 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states:

Defective inlet self-seal valves have been identified. Detachment of a seal inside the valve could result in partial or complete blockage of the burner supply.

On a hopper balloon this failure would result in an uncontrolled descent. In some circumstances this could result in serious injury.

The MCAI requires you inspect fuel gas cylinder to identify whether the cylinder liquid valve is from the affected batch of valves and replace any self-seal valve found from the affected batch.

You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Cameron Balloons Ltd. has issued Service Bulletin No. SB16, dated January 8, 2008; and Service Bulletin No. SB17, dated January 8, 2008. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of the 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 this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are issuing this AD because we evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.

This design cylinder liquid valve may also be installed on balloon models of Cameron Balloons USA. The corrective actions in the AD are specified to Cameron Balloons Ltd. Models, for which the United Kingdom is the State of Design. We are currently evaluating other valve installations on Cameron Balloons USA, for which the United States is the State of Design. We are evaluating these other installations and, based on the evaluation, may consider additional rulemaking on this subject.Start Printed Page 11813

Differences Between This AD and the MCAI or Service Information

We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information.

We might have also required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are described in a separate paragraph of the AD. These requirements take precedence over those copied from the MCAI.

FAA's Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk of the flying public justifies waiving notice and comment prior to adoption of this rule because detachment of a seal inside the valve could result in partial or complete blockage of the burner supply. This failure could result in an uncontrolled descent and serious injury. Therefore, we 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. 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-2008-0195; Directorate Identifier 2008-CE-008-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 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 products 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.

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 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 a regulatory evaluation of the estimated costs to comply with this AD and placed in the AD docket.
