AGENCY: Federal Aviation Administration (FAA), Department of Transportat-
ion (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
--------------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above that would supersede an existing AD. This proposed
AD results from mandatory continuing airworthiness information (MCAI)
originated by an aviation authority of another country to identify and
correct an unsafe condition on an aviation product. The MCAI describes the
unsafe condition as:
Defective burner hoses have been identified which might develop a leak. A
significant leak, if it was ignited, could hazard the balloon and
occupants.
Since the issue of AD G-2003-0010 there have been occurrences of hose
failure in batches not identified in the earlier bulletins. LHAB Service
Bulletin (SB) No. 11 supersedes the earlier SBs and revises the
applicability as required.
The proposed AD would require actions that are intended to address the
unsafe condition described in the MCAI.
DATES: We must receive comments on this proposed AD by May 19, 2008.
ADDRESSES: You may send comments by any of the following methods:

this proposed AD. Send your comments to an address listed under the
ADDRESSES section. Include "Docket No. FAA-2008-0446; Directorate
Identifier 2008-CE-021-AD" at the beginning of your comments. We
specifically invite comments on the overall regulatory, economic,

all comments received by the closing date and may amend this proposed AD
because of those comments.

about this proposed AD.
DISCUSSION
On March 12, 2008, we issued AD 2008-06-15, Amendment 39-15427 (73 FR
13113). That AD required actions intended to address an unsafe condition
on the products listed above.
AD 2008-06-15 was issued as an interim action in order to address the need
for the immediate inspection and pressure test of applicable burner hoses
for leaks and replacement of hoses and end fittings if found defective.
The United Kingdom Civil Aviation Authority, which is the aviation
authority for the United Kingdom, has issued Emergency Airworthiness
Directive AD No. G-2008-0001, dated January 9, 2008 (referred to after
this as "the MCAI"), to correct an unsafe condition for the specified
products.
The MCAI allows for repetitive inspections of applicable burner hoses at
intervals not to exceed ten hours time in service. The MCAI also requires
replacing applicable burner hoses and end fittings before the next annual
inspection.
The Administrative Procedure Act does not permit the FAA to "bootstrap" a
long-term requirement into an urgent safety of flight action where the
rule becomes effective at the same time the public has the opportunity to
comment. The short-term action and the long-term action were analyzed
separately for justification to bypass prior public notice.
We are issuing this proposed AD to address the mandatory replacement of
the burner hose and end fitting.
RELEVANT SERVICE INFORMATION
Lindstrand Balloons Ltd. has issued Lindstrand Hot Air Balloons Ltd.
Service Bulletin No. 11, Issue 1, dated September 24, 2007. 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 PROPOSED 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 proposing this AD because we
evaluated all information and determined the unsafe condition exists and
is likely to exist or develop on other products of the same type design.
DIFFERENCES BETWEEN THIS PROPOSED 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 also have proposed different actions in this AD from those in the
MCAI in order to follow FAA policies. Any such differences are highlighted
in a NOTE within the proposed AD.
COSTS OF COMPLIANCE
We estimate that this proposed AD will affect 422 products of U.S.
registry. We also estimate that it would take about 1 work-hour per
product to comply with the basic requirements of this proposed AD. The
average labor rate is $80 per work-hour.
Based on these figures, we estimate the cost of the proposed AD on U.S.
operators to be $33,760, or $80 per product.
In addition, we estimate that any necessary follow-on actions would take
about 1 work-hour and require parts costing $200, for a cost of $280 per
product. We have no way of determining the number of products that may
need these actions.
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 above, 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); 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 proposed AD and placed it in the AD docket.
LIST OF SUBJECTS IN 14 CFR PART 39
