SUMMARY:

We are superseding Airworthiness Directive (AD) 2014-26-53 and AD 2015-03-02 for certain Airbus Model A319-115, A319-133, A320-214, A320-232, and A320-233 airplanes. AD 2014-26-53 required repetitive detailed visual inspections to detect discrepancies of the wing lower skin surface and inboard main landing gear (MLG) support rib lower flange location fasteners and, depending on findings, accomplishment of applicable corrective action(s). AD 2015-03-02 required repetitive detailed visual inspections of the outboard MLG support rib lower flange fasteners for discrepancies, and corrective actions if necessary. This new AD retains the repetitive detailed visual inspections to detect discrepancies of the fasteners located in the wing lower skin surface and inboard MLG support rib lower flange with extended compliance times and repetitive intervals, and accomplishment of applicable corrective actions. This new AD also retains the repetitive detailed visual inspections of the outboard MLG support rib lower flange fasteners for discrepancies, and corrective actions if necessary. In addition, this new AD adds airplanes to the applicability. This AD was prompted by a determination that certain airplanes were missing from the applicability of AD 2014-26-53 and AD 2015-03-02 and that those airplanes may be affected by the unsafe condition addressed in AD 2014-26-53 and AD 2015-03-02. We are issuing this AD to detect and correct discrepancies of the fasteners at the external surface of the lower wing skin and inboard and outboard MLG support rib lower flanges, which could result in an airplane not meeting its maximum loads expected in service. This condition could result in structural failure.

Discussion

On January 7, 2015, we issued AD 2014-26-53, Amendment 39-18068 (80 FR 3155, January 22, 2015). AD 2014-26-53 applied to certain Airbus Model A319-115, A319-133, A320-214, A320-232, and A320-233 airplanes. AD 2014-26-53 was prompted by reports of failure of certain fasteners located at the wing lower skin surface and inboard MLG support rib lower flange. AD 2014-26-53 required repetitive detailed visual inspections to detect discrepancies of the wing lower skin surface and inboard MLG support rib lower flange location fasteners and, depending on findings, accomplishment of applicable corrective action(s). We issued AD 2014-26-53 to detect and correct discrepancies of the fasteners at the external surface of the lower wing skin and inboard MLG support rib lower flange, which could result in an airplane not meeting its maximum loads expected in service. This condition could result in structural failure.

On January 30, 2015, we issued AD 2015-03-02, Amendment 39-18098 (80 FR 6897, February 9, 2015). AD 2015-03-02 applied to certain Airbus Model A319-115, A319-133, A320-214, A320-232, and A320-233 airplanes. AD 2015-03-02 was prompted by reports of failure of certain fasteners on the MLG support rib lower flange. AD 2015-03-02 required repetitive detailed visual inspections of the outboard MLG support rib lower flange fasteners for discrepancies, and corrective actions if necessary. We issued AD 2015-03-02 to detect and correct discrepancies of the fasteners at the outboard MLG support rib lower flange, which could result in an airplane not meeting its maximum loads expected in service. This condition could result in structural failure.

Since we issued AD 2014-26-53, Amendment 39-18068 (80 FR 3155, January 22, 2015); and AD 2015-03-02, Amendment 39-18098 (80 FR 6897, February 9, 2015); we have determined that certain airplanes were missing from the applicability of AD 2014-26-53 and AD 2015-03-02. Airbus Model A319-132 airplanes are affected with the identified unsafe condition and should have been included in the applicability of those ADs. In addition, we have also determined that the repetitive detailed visual inspections to detect discrepancies of the wing lower skin surface and inboard MLG support rib lower flange could be extended from 8-day intervals to 60-day intervals.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2015-0026, dated February 19, 2015 (referred to after this as the Mandatory Continuing Airworthiness Information, or “the MCAI”), to correct an unsafe condition for certain Airbus Model A319-115, A319-132, A319-133, A320-214, A320-232, and A320-233 airplanes. The MCAI states:

During production of wings, a number of taperlok fasteners were found failed after installation. The fasteners in question are located at the bottom skin of the Main Landing Gear (MLG) reinforcing plate, wing skin and Gear Support Rib 5 lower flange. Based on the results of the preliminary investigation, this affects only certain A319 Start Printed Page 23234and A320 aeroplanes delivered since January 2014.

This condition, if not detected and corrected could reduce the design safety margin of the structure.

Prompted by these findings, EASA issued Emergency AD 2014-0270-E (later revised) [which corresponds to certain requirements of AD 2014-26-53, Amendment 39-18068 (80 FR 3155, January 22, 2015)] to require repetitive detailed inspections (DET) of the bottom skin taperlok fasteners at the MLG Rib 5 footprint location and, depending on findings, accomplishment of applicable corrective action(s).

Since EASA AD 2014-0270R1 [which corresponds to certain requirements of AD 2015-03-02, Amendment 39-18098 (80 FR 6897, February 19, 2015)] was issued, based on in service feedback and further investigation, Airbus issued Revision 01 of Alert Operators Transmission (AOT) A57N006-14 to extend the original 8 calendar days inspection interval to 60 calendar days for the external area and for the internal inboard side. In addition, it was identified that the model A319-132 was missing from the [EASA] AD applicability.

For the reasons described above, this AD retains the requirements of EASA AD 2014-0270R1, which is superseded, to amend the Applicability and to require those actions within the new thresholds and intervals.

This [EASA] AD is still considered to be an interim action and further [EASA] AD action may follow.

Related Service Information Under 1 CFR Part 51

Airbus has issued Airbus Alert Operators Transmission (AOT) A57N006-14, Revision 01, dated February 16, 2015. The service information describes procedures for repetitive detailed visual inspections to detect discrepancies of the wing lower skin surface and inboard and outboard MLG support rib lower flange location fasteners and corrective actions. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.

This service information is reasonably available at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-0930. Or see ADDRESSES for other ways to access this service information.

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 Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because failure of more than two fasteners at the outboard MLG support rib lower flange could result in an airplane not meeting its maximum loads expected in-service. This condition could result in failure of the structure. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days.

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-2015-0930; Directorate Identifier 2015-NM-040-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 148 airplanes of U.S. registry.

The actions required by AD 2014-26-53, Amendment 39-18068 (80 FR 3155, January 22, 2015); and AD 2015-03-2, Amendment 39-18098 (80 FR 6897, February 9, 2015); and retained in this AD, take about 2 work-hours 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 2014-26-53 and AD 2015-03-06 is $170 per product, per inspection cycle.

We also estimate that it will take about 2 work-hours 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 on U.S. operators to be $25,160, or $170 per product, per inspection cycle.

In addition, we estimate that any fastener replacement will take about 3 work-hours and require parts costing $400, for a cost of $655 per fastener replacement. We have no way of determining the number of aircraft that might need these actions.

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.
