## 2795 Federal Register / Vol. 73, No. 11 / Wednesday, January 16, 2008 / Rules and Regulations
flight testing of these new ice shapes indicated that they do not adversely affect the handling characteristics of the Brasilia,the testing did indicate that the stick-shakerto-stick-pusher speed margins for the intercycle ice shapes may be reduced below the minimum standard values set forth in the applicable CTA and FAA Regulations. In order to preserve the original certification stick-shaker-to-stick-pusher margins when operating under the newly defined intercycle icing conditions, an upgraded Stall Warning Computer with new settings for shaker firing angle-of-attack (AOA) is required to be installed. The unsafe condition is reduced ability of the flightcrew to maintain the safe flight and landing of the airplane. The corrective action includes modification of certain electrical wiring and installation of a new Stall Warning Computer. Actions and Compliance

### Airworthiness Directives; Airbus Model **A310 Series Airplanes AGENCY**  

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

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

### : The FAA is superseding an existing airworthiness directive (AD), that applies to certain Airbus Model A310 series airplanes. That AD currently requires modification of certain wires in the right-hand (RH) wing. This new AD requires further modification by installing an additional protection sleeve and segregating route 2S in the RH pylon area. This AD results from analysis of wire routing that revealed that route 2S of the fuel electrical circuit, located in the RH wing, does not provide adequate separation of fuel quantity indication wires from wires carrying 115-volt alternating current (AC). We are issuing this AD to ensure that fuel quantity indication wires are properly separated from wires carrying 115-volt AC. Improper separation of such wires, in the event of wire damage, could lead to a short circuit and a possible ignition source, which could result in a fire in the airplane. **DATES** 

### : This AD becomes effective February 20, 2008.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of February 20, 2008.

On September 3, 2004 (69 FR 45578, July 30, 2004), the Director of the Federal Register approved the incorporation by reference of Airbus Service Bulletin A310

### : Discussion

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that supersedes AD 2004

– 15

– 16, amendment 39

– 13750 (69 FR 45578, July 30, 2004). The existing AD applies to certain Airbus Model A310 series airplanes. That NPRM was published in the Federal Register on November 9, 2007 (72 FR 63506). That NPRM proposed to continue to require modification of certain wires in the right-hand (RH) wing. That NPRM also proposed to require further modification by installing an additional protection sleeve and segregating route 2S in the RH pylon area. Comments

We provided the public the opportunity to participate in the development of this AD. No comments have been received on the NPRM or on the determination of the cost to the public. Conclusion

We have carefully reviewed the available data 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 to comply with this AD.

### 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**

**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:

It has been found that some adhesive tapes used in the interior furnishings do not comply with the applicable flammability requirements. In case of some nearby ignition source, fire may propagate to the aircraft. 

### We are issuing this AD to require actions to correct the unsafe condition on these products. **DATES**

### : 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 November 1, 2007 (72 FR 61822). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

It has been found that some adhesive tapes used in the interior furnishings do not comply with the applicable flammability requirements. In case of some nearby ignition source, fire may propagate to the aircraft. 

### The corrective actions include an inspection to determine the presence of cotton adhesive tape, and replacement of the tape with new tape 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. 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
