### Airworthiness Directives; Airbus **Airplanes**

**AGENCY** 

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

**ACTION** 

### : Final rule.

**SUMMARY** 

### : We are adopting a new airworthiness directive (AD) for certain Airbus Model A319–112, –113, and –132 airplanes; Model A320–211, –212, –214, –231, and –232 airplanes; and Model A321–111 and –131 airplanes. This AD was prompted by a report of two fatigue cracks on the left-hand and right-hand sides of the continuity fittings at the front windshield lower framing on a Model A319 series airplane. This AD requires a high frequency eddy current (HFEC)inspection for any cracking on the lefthand and right-hand sides of the windshield central lower node continuity fittings, and repair if necessary. We are issuing this AD to detect and correct cracking of the windshield central lower node continuity fittings, which could reduce the structural integrity of the airplane.

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


## 41281 Federal Register / Vol. 78, No. 132 / Wednesday, July 10, 2013 / Rules and Regulations

NPRM was published in the Federal Register on October 4, 2012 (77 FR 60658). The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2011–0231, dated December 9, 2011 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI
states:

One operator reported finding two fatigue cracks on continuity fittings at left-hand (LH) and right-hand (RH) sides at the front windshield lower framing on an A319 aeroplane on which Airbus modification (mod.) 22058 had been embodied in production. Airbus mod. 22058 (which is included in Airbus mod. 21999) was introduced to improve the fatigue strength of the windshield front framing by increasing the thickness of framing flanges adjacent to the concerned fittings.

Further analyses have demonstrated that the damage tolerance and fatigue requirements of JAR 25.571 (b) are not met on aeroplanes in post-mod. 22058 configuration.

This condition, if not detected and corrected, could reduce the structural integrity of the affected aeroplanes. 

### Required actions include an HFECinspection for any cracking on the lefthand and right-hand sides of the windshield central lower node continuity fittings, and repair 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 considered the comments received.
Request To Revise HFEC Inspection Requirement

Airbus requested that the one-time HFEC inspection in paragraph (g) of the NPRM (77 FR 60658, October 4, 2012) be revised in anticipation of further rulemaking by the EASA, which would mandate the airworthiness limitation inspection task and would correspond with the one-time HFEC inspection.

We disagree with Airbus’s request. We have determined that publishing this final rule without any further delay is in the interest of safety of the flying public. However, we will consider additional AD rulemaking, if appropriate, in the future. We have not revised this final rule in this regard. Request for Approval of Repair

Airbus requested consideration that each Airbus Repair Approval Sheet (RAS) be approved under ‘‘AIRBUS DOA EASA.21J.031,’’ provided that this is done after cracking is reported. Airbus stated that this would be an approved method for repair as required by paragraph (g) of the NPRM (77 FR 60658, October 4, 2012).

We agree. Airbus is an EASAdelegated agent; therefore, a RAS approved under Airbus Design Organization Approval (DOA) EASA.21J.031 would be a method of compliance for a repair required by this AD. We have not changed the final rule in this regard. Request To Update Address for the Manufacturer

Airbus requested that the address for the manufacturer be updated. Airbus stated that in paragraph (k)(2) of the NPRM (77 FR 60658, October 4, 2012), ‘‘EAS’’ should be replaced with ‘‘EIAS.’’

We agree with Airbus’s request to update the manufacturer’s address. Paragraphs (k)(2) and (l)(3) of this final rule have been updated accordingly.

Conclusion

We reviewed the available data, including the comments received, and determined that air safety and the public interest require adopting the AD with the change described previously— and minor editorial changes. We have determined that these changes:

• Are consistent with the intent that was proposed in the NPRM (77 FR 60658, October 4, 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 60658, October 4, 2012). Costs of Compliance

We estimate that this AD will affect 105 products of U.S. registry. We alsoestimate that it will take about 20 workhours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $178,500, or $1,700 per product.

We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in 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 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

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 60658, October 4, 2012), the regulatory evaluation, any comments received, and other information.
