Airworthiness Directives; Lindstrand Balloons Ltd. Models 42A, 56A, 60A, 69A, 77A, 90A, 105A, 120A, 150A, 180A, 210A, 240A, 260A, and 310A Balloons
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (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:
Federal eRulemaking Portal: Go to http:// www.regulations.gov. Follow the instructions for submitting comments.

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.

Subject
(d) Air Transport Association of America (ATA) Code 28: Fuel.
Reason
(e) The mandatory continuing airworthiness information (MCAI) states:
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 MCAI requires you inspect the hose and to identify whether the hose is from the affected batch of hoses and to inspect and replace any defective hose and end fitting from the affected batch.
Actions and Compliance
(f) Do the following unless already done:
(1) Before further flight as of April 1, 2008 (the compliance date retained from AD 2008-06-15), inspect the balloon burner to determine whether it has a hose from the affected batch of hoses following Lindstrand Hot Air Balloons Ltd. Service Bulletin No. 11,
Issue 1, dated September 24, 2007.
(2) If as a result of the inspection required by (f)(1) of this
AD you find a hose from the affected batch, before further flight, inspect for leaks and conduct a pressure test following Lindstrand
Hot Air Balloons Ltd. Service Bulletin No. 11, Issue 1, dated
September 24, 2007, and repetitively thereafter inspect and conduct a pressure test at intervals not to exceed 10 hours time-in-service.
(3) If as a result of any inspection or test required by (f)(2) of this AD you find a defective hose, before further flight, replace it and the end fitting with a new hose and new end fitting following the maintenance manual. This action terminates the repetitive requirement in (f)(2) of this AD.
(4) Unless already done, within 12 months after the effective date of this AD, replace any hose from the affected batch with a new hose and end fitting. After doing this replacement, no further action is required by this AD.
Note 1: At any time after the effective day of this AD, you may replace the hose and end fitting to terminate the repetitive inspection and testing requirements of this AD.
FAA AD Differences
Note 2: This AD differs from the MCAI and/or service information as follows: No differences.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
Standards Office, FAA, has the authority to approve AMOCs for this
AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Taylor Martin, Aerospace Engineer, FAA, Small
