2016-13856. Airworthiness Directives; Airbus Airplanes

AGENCY:

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

ACTION:

Final rule; request for comments.

SUMMARY:

We are superseding Airworthiness Directive (AD) 2016-09-11 for certain Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and Model A340-200 and -300 series airplanes. AD 2016-09-11 required removing fasteners, doing a rototest inspection of fastener holes, installing new fasteners, oversizing the holes and doing rototest inspections for cracks if necessary, and repairing any cracking that is found. This new AD requires the same actions as AD 2016-09-11, but includes Model A330-300 series airplanes in paragraph (g)(2) of this AD. This AD was prompted by the discovery of missing affected airplanes in paragraph (g)(2) of AD 2016-09-11 that resulted from converting a table in the proposed AD to text in AD 2016-09-11. We are issuing this AD to detect and correct cracking on certain holes of certain frames of the center wing box (CWB), which could affect the structural integrity of the airplane.

DATES:

This AD is effective June 29, 2016.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of June 13, 2016 (81 FR 27986, May 9, 2016).

We must receive comments on this AD by July 29, 2016.

SUPPLEMENTARY INFORMATION:

Discussion

On April 21, 2016, we issued AD 2016-09-11, Amendment 39-18509 (81 FR 27986, May 9, 2016) (“AD 2016-09-11”), for certain Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and Model A340-200 and -300 series airplanes. AD 2016-09-11 was prompted by reports that cracks were found on an adjacent hole of certain frames of the CWB. AD 2016-09-11 required removing fasteners, doing a rototest inspection of fastener holes, installing new fasteners, oversizing the holes and doing rototest inspections for cracks if necessary, and repairing any cracking that was found. We issued AD 2016-09-11 to detect and correct cracking on certain holes of certain frames of the CWB that could affect the structural integrity of the airplane.

Since we issued AD 2016-09-11, we discovered missing affected airplanes in paragraph (g)(2) of AD 2016-09-11 that resulted from converting a table to text in that AD. We stated in the preamble of AD 2016-09-11 that we revised the format of paragraph (g) of that AD, at the request of the Office of the Federal Register, by converting the table to text. We also stated this change to the format does not affect the requirements of that paragraph.

However, in converting the table to text, we inadvertently omitted Model A330-300 series airplanes from paragraph (g)(2) of AD 2016-09-11. We have changed paragraph (g)(2) of this AD to include Model A330-300 series airplanes.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014-0149, dated June 13, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and Model A340-200 and -300 series airplanes. The MCAI states:

During accomplishment of A330 Airworthiness Limitation Item (ALI) task 57-11-04 on the rear fitting of the Frame (FR) 40 between stringers 38 and 39 on both [left-hand] LH/[right-hand] RH sides, cracks were found on an adjacent hole. After reaming at second oversize of the subject hole, the crack was still present.

Other crack findings on this adjacent hole have been reported on A330 and A340-200/-300 aeroplanes as a result of sampling inspections.

This condition, if not detected and corrected, could affect the structural integrity of the aeroplane.

For the reasons described above, this [EASA] AD requires removal of the fasteners and repetitive rototest inspections of fastener holes at FR40 vertical web located above Center Wing Box (CWB) lower panel reference and/or below CWB lower panel reference on both sides and, depending on findings, accomplishment of the applicable corrective actions.

Note: These holes affected by this [EASA] AD are different from the ones affected by EASA AD 2009-0001 [http://ad.easa.europa.eu/​blob/​easa_​ad_​2009_​0001.pdf/​AD_​2009-0001_​1].

Required actions also include oversizing certain holes, installing new fasteners, and repairing any cracking that is found. The initial compliance times range from 13,500 to 30,900 flight cycles, or 57,000 to 162,000 flight hours, depending on airplane operation and utilization. The repetitive compliance times are 7,400 flight cycles/24,300 flight hours or 5,950 flight cycles/40,400 flight hours from ALI embodiment. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-6899.

Related Service Information Under 1 CFR Part 51

Airbus has issued the following service information. The service information describes procedures for removing the fasteners and doing a repetitive rototest inspection of fastener holes at FR40 vertical web on both sides, installing new fasteners in transition fit, and oversizing the holes.

• Airbus Service Bulletin A330-57-3114, dated March 12, 2013.
• Airbus Service Bulletin A330-57-3115, dated April 4, 2013.
• Airbus Service Bulletin A330-57-3116, dated March 12, 2013.
• Airbus Service Bulletin A340-57-4123, dated March 12, 2013.
• Airbus Service Bulletin A340-57-4124, Revision 01, dated August 22, 2013.
• Airbus Service Bulletin A340-57-4125, dated March 12, 2013.

This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.

FAA's Determination and Requirements of This 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 issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of these same type designs.

FAA's Justification and Determination of the Effective Date

We are superseding AD 2016-09-11 to correct an error in the regulatory text that we made when we converted a table to text in paragraph (g)(2) of AD 2016-09-11. No other changes have been made to AD 2016-09-11. Therefore, we determined that notice and opportunity for prior public comment are unnecessary.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include “Docket No. FAA-2016-6899; Directorate Identifier 2016-NM-066-AD” at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments.

We will post all comments we receive, without change, to http://www.regulations.gov,, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD.

Costs of Compliance

We estimate that this AD affects 35 airplanes of U.S. registry.

We estimate the following costs to comply with this AD:

Estimated Costs

Action	Labor cost	Parts cost	Cost per product	Cost on U.S. operators
Inspection	78 work-hours × $85 per hour = $6,630 per inspection cycle	$0	$6,630 per inspection cycle	$232,050 per inspection cycle.

We estimate the following costs to do any necessary repairs that will be required based on the results of the inspection. We have no way of determining the number of airplanes that might need this repair:

On-Condition Costs

Action	Labor cost	Parts cost	Cost per product
Oversize, installation, and inspection	98 work-hours × $85 per hour = $8,330	$136,400	$144,730

We have received no definitive data that will enable us to provide cost estimates for the on-condition repair 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.
