CFR Citation: 14 CFR Part 39

Docket ID: [Docket No. FAA-2008-0446; Directorate Identifier 2008-CE-021-AD; Amendment 39-15568; AD 2008-13-05]

RIN ID: RIN 2120-AA64

NOTICE: RULES

ACTION: Airworthiness Directives:

DOCUMENT ACTION: Final rule.

SUBJECT CATEGORY: Airworthiness Directives; Lindstrand Balloons Ltd. Models 42A, 56A, 60A, 69A, 77A, 90A, 105A, 120A, 150A, 180A, 210A, 240A, 260A, and 310A Balloons

DATES: This AD becomes effective July 23, 2008.

As of April 1, 2008 (73 FR 13113, March 12, 2008), the Director of the Federal Register approved the incorporation by reference of Lindstrand Hot Air Balloons Ltd. Service Bulletin No. 11, Issue 1, dated September 24, 2007, listed in this AD.

DOCUMENT SUMMARY: We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 G20030010 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.
We are issuing this AD to require actions to correct the unsafe condition on these products.

SUMMARY: Lindstrand Balloons Ltd. Models 42A, 56A, 60A, 69A, 77A, 90A, 105A, 120A, 150A, 180A, 210A, 240A, 260A, and 310A Balloons,

SUPPLEMENTAL INFORMATION

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on April 18, 2008 (73 FR 21072), and proposed to supersede AD 20080615, Amendment 3915427 (73 FR 13113, March 12, 2008). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states that:

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 G20030010 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 to identify whether the hose is from the affected batch of hoses and to inspect for defective hoses and end fittings, immediately replace any defective hose and end fittings, and eventually replace any of the hoses and end fittings from the affected batch that are not defective.

Comments

We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.

Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed.
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 also have required 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 AD.

Costs of Compliance

We estimate that this AD will affect 422 products of U.S. registry. We also estimate that it will take about 1 workhour per product to comply with basic requirements of this AD. The average labor rate is $80 per workhour.

Based on these figures, we estimate the cost of this AD to the U.S. operators to be $33,760 or $80 per product.

In addition, we estimate that any necessary followon actions would take about 1 workhour 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 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 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 it in the AD Docket.

Examining the AD Docket

You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Office (telephone (800) 6475527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]

Subject
(d) Air Transport Association of America (ATA) Code 28: Fuel. [[Page 34624]]
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 G20030010 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 to identify whether the hose is from the affected batch of hoses and to inspect for defective hoses and end fittings, immediately replace any defective hose and end fittings, and eventually replace any of the hoses and end fittings from the affected batch that are not defective. Actions and Compliance
(f) Do the following unless already done:
(1) Before further flight after April 1, 2008 (the compliance date retained from AD 20080615), 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 timeinservice. (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 FAAapproved instructions. The Lindstrand Balloons Ltd. maintenance manual contains FAAapproved instructions. This action terminates the repetitive requirement in (f)(2) of this AD.
(4) Unless already done, within 12 months after July 23, 2008 (the effective date of this AD), replace any hose from the affected batch with a new hose and end fitting following FAAapproved instructions. The Lindstrand Balloons Ltd. maintenance manual contains FAAapproved instructions. After doing this replacement, no further action is required by this AD.

Note 1: At any time after July 23, 2008 (the effective date 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.
