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 39—AIRWORTHINESS DIRECTIVES** 

■ 

### 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

**§ 39.13 [Amended]**

■ 

### 2. The FAA amends § 39.13 by adding the following new AD:

2013–03–10 Lindstrand Hot Air Balloons Ltd: Amendment 39–17345; Docket No. FAA–2012–1134; Directorate Identifier 2012–CE–034–AD.
(a) Effective Date

This airworthiness directive (AD) becomes effective March 19, 2013.

(b) Affected ADs

None. (c) Applicability

This AD applies to all hot air balloons, certificated in any category, equipped with Lindstrand Hot Air Balloons Ltd female ACME threaded hose connectors, part numbers (P/Ns) HS6139 and HS6144, all serial numbers.
(d) Subject

Air Transport Association of America (ATA) Code 14: Hardware.

(e) Reason

This AD was prompted by 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 insufficient tightness of the threaded hose connector in the assembly area that could result in fuel leakage. We are issuing this AD to detect and correct insufficient tightness of the threaded hose connector in the assembly area. This condition, if not corrected, could result in fuel leakage and lead to an inflight fire.
(f) Actions and Compliance

Unless already done, do the following actions:

(1) Within the next 60 days after March 19, 2013 (the effective date of this AD), inspect the female ACME threaded hose connectors, (P/Ns) HS6139 and HS6144, for leaking following the Accomplishment Instructions of Lindstrand Hot Air Balloons Ltd Service Bulletin No. 12, Issue 2, dated May 10, 2012.

(2) If fuel leakage is detected in the inspection required in paragraph (f)(1) of this AD, before further flight, tighten the threaded hose connector to the correct torque following Lindstrand Hot Air Balloons Ltd Service Bulletin No. 12, Issue 2, dated May 10, 2012.

(3) If, after March 19, 2013 (the effective date of this AD), you install on any balloon an ACME threaded hose connector, (P/Ns) HS6139 or HS6144, manufactured by Lindstrand Hot Air Balloons Ltd and supplied as a spare part between January 1, 2011, and September 1, 2011, before further flight, you must comply with the actions of this AD.

(4) Although the European Aviation Safety Agency (EASA) MCAI allows the pilot-owner to do the inspection and correction required in paragraphs (f)(1), (f)(2), and (f)(3) of this AD, the U.S. regulatory system requires all actions of this AD be done by a certified mechanic.
(g) Other FAA AD Provisions

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.

**SUPPLEMENTARY INFORMATION** 

### :

Discussion

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 October 12, 2012 (77 FR 62182). That NPRM proposed to correct an unsafe condition for the specified products. The Mandatory Continuing Airworthiness Information (MCAI)
states:

[T]he FAA published Special Federal Aviation Regulation (SFAR) 88, and the Joint Aviation Authorities (JAA) published Interim Policy INT/POL/25/12.

In the framework of these requirements, EASA [European Aviation Safety Agency] have determined that the electrical power supply circuits of certain fuel pumps, installed on A300/A300–600, A310 and A300–600ST aeroplane, for which the canisters become uncovered during normal operation, could, under certain conditions, create an ignition source in the tank vapour
space.

This condition, if not corrected, could result in a fuel tank explosion and consequent loss of the aeroplane.

To address this potential unsafe condition, Airbus developed a modification which includes the installation of Ground Fault Interrupters (GFI) into the inner, centre, and trim tank fuel pump control circuits, providing additional system protection by electrically isolating the pump in case of a ground fault condition downstream of the GFI.

For the reasons described above, this [EASA] AD requires modification of the affected fuel pumps control circuit by installing GFI. 

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

Comments

We gave the public the opportunity to participate in developing this AD. We have considered the comments received. No Requests or Objections

FedEx stated that the requirements and number of work-hours will fit into its maintenance schedule, and the manufacturer provided an estimate of 90 to 99 days’ lead time on parts. FedEx also stated that the proposed actions will not require any special procedures or equipment. We infer that FedEx does not object to any requirements of this AD. Request To Extend Compliance Time

United Parcel Service (UPS) noted that in Airbus Mandatory Service Bulletin A300–28–3104, dated February 28, 2012, Airbus provided a parts lead time estimate of 120 days. UPS stated that the 120 days would reduce the time left to accomplish the work described in that service bulletin. UPS requested that parts lead times be taken into consideration when the FAA develops compliance times for ADs. We infer that UPS requested the compliance time be extended to accommodate the 120-day parts lead time.

We disagree with the request to extend the compliance time. We considered the parts availability and lead time when developing the compliance time. We have not changed this AD in this regard. However, under the provisions of paragraph (h)(1) of this AD, we may approve requests for an alternative method of compliance (AMOC) if data are submitted to substantiate that such an adjustment would provide an acceptable level of safety.

Conclusion

We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial changes. We have determined that these minor changes:

• Are consistent with the intent that was proposed in the NPRM (77 FR 62182, October 12, 2012) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 62182, October 12, 2012). Costs of Compliance

We estimate that this AD will affect 162 products of U.S. registry. We alsoestimate that it will take about 6 workhours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $17,680 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $2,946,780, or $18,190 per product. 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 the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);

3. Will not affect intrastate aviation in Alaska; and


## 9789 Federal Register / Vol. 78, No. 29 / Tuesday, February 12, 2013 / Rules and Regulations

4. 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 Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM (77 FR 62182, October 12, 2012), the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 647–5527) is in the **ADDRESSES**
