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.

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

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.

[[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.

Subject

    (d) Air Transport Association of America (ATA) Code 28: Fuel.

Reason

    (e) The mandatory continuing airworthiness information (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 the fuel 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.

Actions and Compliance

    (f) Unless already done, do the following actions.
    (1) Before further flight as of March 25, 2008. (the effective 
date of this AD), inspect any gas cylinder to identify whether the 
cylinder liquid valve is from the affected batch of valves following 
Cameron Balloons Ltd. Service Bulletin No. SB16, dated January 8, 
2008; and Cameron Balloons Ltd. Service Bulletin No. SB17, dated 
January 8, 2008.
    (2) For single cylinder balloons or multi-cylinder hopper 
balloons: Before further flight, if you find any cylinder liquid 
valve from the affected batch (rego-type cylinder liquid valve P/N 
CB-0824-0001 which is date-stamped from 12/05 through 08/06) 
installed as a result of the inspection required by paragraph (f)(1) 
of this AD, replace the self-seal valve following Cameron Balloons 
Ltd. Service Bulletin No. SB16, dated January 8, 2008; and Cameron 
Balloons Ltd. Service Bulletin No. SB17, dated January 8, 2008.
