**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to supersede airworthiness directive (AD) 2011–17– 08, which applies to all Airbus Model A330–200 series airplanes, Model A330–200 Freighter series airplanes, and Model A330–300 series airplanes. AD 2011–17–08 currently requires revising the maintenance program by incorporating certain Airworthiness Limitation Items (ALIs). Since we issued AD 2011–17–08, Airbus has revised a certain ALI document, which specifies more restrictive instructions and/or airworthiness limitations. This proposed AD would revise the maintenance or inspection program, as applicable, to incorporate new or revised structural inspection requirements. We are proposing this AD to detect and correct fatigue cracking, damage, and corrosion in certain structure, which could result in reduced structural integrity of the airplane.

**DATES :**  We must receive comments on this proposed AD by May 23, 2014.

Discussion

On August 2, 2011, we issued AD 2011–17–08, Amendment 39–16772 (76 FR 53303, August 26, 2011), which superseded AD 2006–09–07, Amendment 39–14577 (71 FR 25919, May 3, 2006). AD 2011–17–08 required actions intended to address an unsafe condition on the products listed above.

Since we issued AD 2011–17–08, Amendment 39–16772 (76 FR 53303, August 26, 2011), the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0211, dated October 12, 2012 (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:

The airworthiness limitations are currently defined and published in the Airbus A330 Airworthiness Limitations Section (ALS).

The airworthiness limitations applicable to the Damage Tolerant Airworthiness Limitation Items (DT ALI) are currently specified in Airbus A330 ALI, Airbus Document reference AI/SE–M4/95A.0089/97, which is approved by EASA and referenced in Airbus ALS Part 2.

Issue 19 of the Airbus A330 ALI Document introduces more restrictive maintenance requirements and/or airworthiness limitations. Failure to comply with the relevant instructions could result in an unsafe condition.

For the reasons described above, this [EASA] AD retains the requirements of EASA AD 2010–0174 [ http://ad.easa.europa.eu/ blob/easa

_ ad

_ 1 ] [which corresponds to FAA AD 2011–17–08, Amendment 39–16772 (76 FR 53303, August 26, 2011)], which is superseded, and requires the implementation of the new or more restrictive maintenance instructions and/or airworthiness limitations as specified in Airbus A330 ALI Document reference AI/SE–M4/95A.0089/97 issue 19.

The unsafe condition is fatigue cracking, damage, and corrosion in certain structure, which could result in reduced structural integrity of the airplane. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating it in Docket No. FAA–
2014–0190.

Relevant Service Information

Airbus has issued the following service information.


### 19295 Federal Register / Vol. 79, No. 67 / Tuesday, April 8, 2014 / Proposed Rules

• Airbus Document AI/SE–M4/ 95A.0089/97, ‘‘A330 Airworthiness Limitation Items,’’ Issue 19, dated March 23, 2012.

• Variations to Airbus Document AI/ SE M4/95A.0089/97, ‘‘A330 Airworthiness Limitation Items,’’ Issue 19, dated March 23, 2012 (variations reference 0GVLG120018/C0S, dated October 24, 2012.

• Variation to Airbus Document AI/ SE M4/95A.0089/97, ‘‘A330 Airworthiness Limitation Items,’’ Issue 19, dated March 23, 2012 (variation reference 0GVLG120022/C0S, dated December 21, 2012).

• Variations to Airbus Document AI/ SE M4/95A.0089/97, ‘‘A330 Airworthiness Limitation Items,’’ Issue 19, dated March 23, 2012 (variations reference 0GVLG130002/C01, dated March 26, 2013).

The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This Proposed AD

This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design.

This proposed AD would require revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (l)(1) of this proposed AD. The request should include a description of changes to the required actions that will ensure the continued damage tolerance of the affected
structure. Costs of Compliance

We estimate that this proposed AD affects 30 airplanes of U.S. registry.

The actions that are required by AD 2011–17–08, Amendment 39–16772 (76 FR 53303, August 26, 2011), and retained in this proposed AD take about 1 work-hour per product, at an average labor rate of $85 per work-hour. Based on these figures, the estimated cost of the actions that were required by AD 2011–17–08 is $85 per product.

We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $2,550, or $85 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 proposed regulation:

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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 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. Amend § 39.13 by removing airworthiness directive (AD) 2011–17– 08, Amendment 39–16772 (76 FR 53303, August 26, 2011), and adding the following new AD:

**Airworthiness Directives; Airbus Airplanes** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for all Airbus Model A300 series airplanes, Model A300 B4–600, B4–600R, and F4– 600R series airplanes, and Model A300 C4–605R Variant F airplanes (collectively called Model A300–600 series airplanes). This proposed AD was prompted by a report of chafing found on the overflow sensor harness of the surge tank, and subsequent contact between the electrical wiring and fuel tank structure. This proposed AD would require a one-time inspection for chafing of the overflow sensor harness and structural damage of the outer tank, and repair if necessary. This proposed AD would also require modification of the sensor harness. We are proposing this AD to prevent chafing of the harness and subsequent contact between the electrical wiring and fuel tank structure, which could result in electrical arcing and a fuel tank explosion and consequent loss of the airplane.

**DATES :**  We must receive comments on this proposed AD by May 23, 2014.
