 Department of Transportation Federal Aviation Administration 14 CFR Part 39
[Docket No. FAA-2010-0859; Directorate Identifier 2010-NM-113-AD; Amendment 39-16614; AD 2011-05-05]
RIN 2120-AA64
 AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
 ACTION: Final rule.
 SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This 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: 
 * * * [T]here is a possible path for fluid ingress, resulting in connector internal arcing and hydraulic system malfunction. In addition, as the connectors are located in areas adjacent to fuel tanks, such arcing associated with the presence of a fuel leakage could lead to an uncontrolled fire. 
 We are issuing this AD to require actions to correct the unsafe condition on these products.
 DATES: This AD becomes effective March 31, 2011. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of March 31, 2011.
 ADDRESSES: You may examine the AD docket on the Internet at

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 September 29, 2010 (75 FR 60010). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states: Several A330 and A340 operators have reported in service occurrences of hydraulic pump electrical motor connector internal arcing, resulting in: —Either false hydraulic system overheat Electronic Centralized Aircraft Monitoring (ECAM) warnings —and/or hydraulic pump electrical motor malfunction. Investigations have shown that, due to the manufacturing tolerances of the cables and the connectors rear grommet, there is a possible path for fluid ingress, resulting in connector internal arcing and hydraulic system malfunction. In addition, as the connectors are located in areas adjacent to fuel tanks, such arcing associated with the presence of a fuel leakage could lead to an uncontrolled fire. In order to protect the hydraulic pump electrical motor connectors against fluid ingress from the rear of the connector grommet and prevent false hydraulic system overheat ECAM warnings and/or hydraulic pump electrical motor malfunction, this AD requires modification of the three hydraulic pump electrical motor connectors associated to the Blue, Yellow and Green hydraulic systems. This Revision 1 is issued to delete Airbus modifications 55923S18878 and 55924S19452 from the applicability of this AD. The modification adds heat shrink sleeves to certain cable contacts and a sealing plug to the connector free cavity. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information The NPRM referred to the service information in the following table as the applicable sources of service information. Table—Service Information Cited in the NPRM

 Comments We gave the public the opportunity to participate in developing this AD. We considered the comment received. Support for the NPRM Delta stated that it agreed with the intent of the rule. Request To Revise Compliance Times Delta requested that we revise the compliance time from within 3,600-flight-hours to 10,000 flight hours or 24 months after the effective date of the AD to allow operators the flexibility to schedule the task during routine maintenance opportunities. Delta stated that revising the compliance times would be more congruous with AD 2008-06-25, Amendment 39-15437 (73 FR 14659). Delta stated that it reviewed its maintenance records for Model A330 airplanes, and it has not experienced a single failure of a hydraulic electric motor pump electrical connector in approximately 738,000 hours of operation. Furthermore, Delta stated that there have been no cases of fire as a result of arcing within the hydraulic electric motor pump connectors and that arcing within the connectors without the presence of flammable fluid does not constitute a safety issue. We do not agree with the commenter's request to extend the compliance time. In developing an appropriate compliance time for this action, we considered the safety implications, parts availability, and normal maintenance schedules for the timely accomplishment of the modification. In consideration of these items, we have determined that a 3,600-flight-hour compliance time will ensure an acceptable level of safety and allow the modifications to be done during scheduled maintenance intervals for most affected operators. However, under the provisions of paragraph (i)(1) of the final rule, we will consider requests for approval of an extension of the compliance time if sufficient data are submitted to substantiate that the change would provide an acceptable level of safety. We have not changed the final rule in regard to this issue. Request To Include Reference for Additional Tooling Delta requested that we revise the NPRM to include Airbus Service Bulletin Information Telex (SBIT) 10-0039, dated October 14, 2010, or that we delay issuing the final rule until Revision 03 of Airbus Mandatory Service Bulletin A330-92-3088 is released. Delta stated that Airbus has informed operators that Airbus Mandatory Service Bulletin A330-92-3088 is being revised to include direct references to the adequate tool part numbers. We disagree with the request to include the SBIT and with the request to delay the final rule until Revision 03 of Airbus Mandatory Service Bulletin A330-92-3088 is released. Although the SBIT does contain tooling information, this AD does not mandate which tooling to use. We did not revise the final rule in this regard. Conclusion We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We determined that these changes will not increase the economic burden on any operator or increase the scope of the AD. 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 our FAA policies. Any such differences are highlighted in a Note within the AD. Costs of Compliance We estimate that this AD will affect 43 products of U.S. registry. We also estimate that it will take about 13 work-hours 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 $877 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 $85,226 or $1,982 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 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); 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
