### : Federal Aviation Administration (FAA), Department of Transportation (DOT). **ACTION** 

### : Final rule. **SUMMARY** 

### : The FAA is superseding an existing airworthiness directive (AD), which applies to all Airbus Model A330

– 200, A330

– 300, A340

– 200, and A340

– 300 series airplanes. That AD currently requires an accelerated schedule of repetitive testing of the elevator servo control loops, and corrective actions if necessary. This new AD retains the existing requirements, reduces the applicability of the existing AD, and adds terminating actions. This AD results from reports of failed elevator servo controls due to broken guides. We are issuing this AD to prevent failure of the elevator servo controls during certain phases of takeoff, which could result in an unannounced loss of elevator control and consequent reduced controllability of the airplane. **DATES** 

### : This AD becomes effective April 16, 2008.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of April 16, 2008.

On November 29, 2005 (70 FR 69065, November 14, 2005), the Director of the Federal Register approved the incorporation by reference of Airbus All Operators Telex A330

– 27A3138, Revision 01, dated October 3, 2005; and Airbus All Operators Telex A340

### : Discussion

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that supersedes AD 2005

– 23

– 10, amendment 39

– 14368 (70 FR 69065, November 14, 2005). The existing AD applies to all Airbus Model A330

– 200, A330

– 300, A340

– 200, and A340

– 300 series airplanes. That NPRM was published in the Federal Register on November 26, 2007 (72 FR 65906). That NPRM proposed to retain the existing requirements, reduce the applicability of the existing AD, and add terminating actions. Comments

We provided the public the opportunity to participate in the development of this AD. We have considered the comment that has been received on the NPRM. Request To Extend Compliance Time for the Modification

Air Transport Association (ATA) and one of its members, Northwest Airlines (NWA), state that the terminating action specified in the proposed AD should be mandated at a maximum of 24 months after the effective date for coordination with the aircraft C-check intervals. NWA adds that the repetitive tests of the elevator servo-loops will ensure continued safe operation until terminating action is accomplished.

We do not agree with the request from ATA and NWA to extend the compliance time. In developing an appropriate compliance time for this action, we considered the urgency associated with the subject unsafe condition, the availability of required parts, and the practical aspect of accomplishing the required modification within a period of time that corresponds to the normal scheduled maintenance for most affected operators. In light of these items, we have determined that a 17- month compliance time is appropriate. However, according to the provisions of paragraph (q) of the AD, we may approve requests to adjust the compliance time if the request includes data that justify that the new compliance time would provide an acceptable level of safety. Conclusion

We have carefully reviewed the available data, including the comment that has been submitted, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance

The following table provides the estimated costs for U.S. operators of the affected Model A330

– 200 and A330

– 300 series airplanes to comply with this AD.

### Currently, there are no affected Model A340

– 200 and A340

– 300 series airplanes on the U.S. Register. However, if an affected airplane is imported and placed on the U.S. Register in the future, the modification would take about 10 work hours, at an average labor rate of $80 per work hour. The manufacturer states that it will supply required parts to the operators at no cost. Based on these figures, we estimate the cost of this AD for Model A340

– 200 and A340

– 300 series airplanes to be $800 per airplane. 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 have 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 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. See the **ADDRESSES**

### : 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 December 20, 2007 (72 FR 72270). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

Cracking has been found on the centre fuselage top aft longeron at Rib ‘ 0 ’ on an inservice aircraft. Subsequent investigation has indicated that the currently defined threshold and repeat inspection period must be reduced, and the area of inspection expanded for the BAe 146 series 100 and 200. For the BAe146 series 300, only the repeat inspection period must be reduced, and the area of inspection expanded. 

### Cracking on the center fuselage top aft longeron at Rib ‘ 0, ’ could result in reduced structural integrity of the airplane. Corrective actions include repetitive inspections of the center fuselage top aft longeron for cracking and repair/replacement if necessary. 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 received no comments on the NPRM or on the determination of the cost to the public. Revision to the Reference to the Nondestructive Testing (NDT) Manual

We have removed the reference to the BAE Systems (Operations) Limited BAe 146/Avro 146

–RJ Series NDT Manual Part 6 20

– 00

– 03 from paragraphs (f)(2)(iii) and (f)(5)(iii) of this AD. The appropriate source of service information for doing the inspection and repair specified in paragraphs (f)(2)(iii) and (f)(5)(iii) of this AD is BAE Systems (Operations) Limited Inspection Service Bulletin ISB.53

– 173, Revision 2, dated March 28, 2006. The Accomplishment Instructions of the service bulletin refer to the NDT manual. We have added Note 1 and Note 3 to this AD to clarify that the service bulletin refers to the NDT manual as a secondary source of service information for doing the inspection. Conclusion

We reviewed the available data and determined that air safety and the public interest require adopting the AD with the change 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.
