2012-24175. Airworthiness Directives; Airbus Airplanes

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

We propose to supersede an existing airworthiness directive (AD) that applies to certain Airbus Model A318, A319, A320, and A321 series airplanes. The existing AD currently requires one-time and repetitive inspections of specific areas and, when necessary, corrective actions for those rudders where production rework has been identified. Since we issued that AD, we have determined that additional inspections and corrective actions are necessary to address the identified unsafe condition, and that additional airplanes with certain rudders are subject to the identified unsafe condition. This proposed AD would add airplanes with certain rudders to the AD applicability; change an inspection type for certain reinforced rudder areas; require pre-inspections and repairs if needed; and require permanent restoration of vacuum loss holes. This proposed AD would also require additional inspections for certain rudders and repair if needed; and require replacement of certain rudders with new rudders. We are proposing this AD to detect and correct extended de-bonding, which might degrade the structural integrity of the rudder. The loss of the rudder leads to degradation of the handling qualities and reduces the controllability of the airplane.

DATES:

We must receive comments on this proposed AD by November 16, 2012.

Discussion

On October 26, 2010, we issued AD 2010-23-07, Amendment 39-16496 (75 FR 68181, November 5, 2010; corrected December 17, 2010 (75 FR 78883)). That AD required actions intended to address an unsafe condition on the products listed above.

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2010-0164, dated August 5, 2010 (referred to after this as “the MCAI”), to correct an unsafe condition for the specified products. The MCAI states:

Surface defects were visually detected on the rudder of one A319 and one A321 in-service aeroplane.

Investigation has determined that the defects reported on both rudders corresponded to areas that had been reworked in production. The investigation confirmed that the defects were a result of de-bonding between the skin and honeycomb core.

An extended de-bonding, if not detected and corrected, may degrade the structural integrity of the rudder. The loss of the rudder leads to degradation of the handling qualities and reduces the controllability of the aeroplane.

EASA AD 2009-0141 required inspections of specific areas and, when necessary, the application of corrective actions for those rudders where production reworks have been identified.

This [EASA] AD retains the requirements of EASA AD 2009-0141 (addressing the populations of rudders affected by AOT A320-55-1038), which is superseded, and requires:

— a local ultrasonic inspection for reinforced area instead of the local thermography inspection, which is maintained for non-reinforced areas, and

— additional work performance for rudders on which this thermography inspection has been performed in the reinforced area, and

— additional work performance for some rudders on which an additional area requiring inspections is defined.

This [EASA] AD also addresses the populations of rudders affected by AOT A320-55-1039 and Airbus SB A320-55-1035, A320-55-1036 and A320-55-1037 which were not included in EASA AD 2009-0141.

Part number (P/N) D554 71000 020 00 serial number (S/N) TS-1494, and P/N D554 71002 000 00 0002 S/N TS-2212 are listed in Appendix A of EASA AD 2010-0164, dated August 5, 2010. These two items are listed in table 6 of this proposed AD, because they were not listed in previous AD 2010-23-07, Amendment 39-16496 (75 FR 68181, November 5, 2010; corrected December 17, 2010 (75 FR 78883)). This proposed AD requires the permanent restoration of vacuum loss holes and does not allow the temporary restoration with self-adhesive patches, or temporary restoration with resin that is specified in the MCAI. You may obtain further information by examining the MCAI in the AD docket.

Relevant Service Information

Airbus has issued the following service information.

• Airbus All Operators Telex (AOT) A320-55A1038, dated April 22, 2009.
• Airbus AOT A320-55A1039, dated November 4, 2009.
• Airbus Service Bulletin A320-55-1035, Revision 01, dated July 2, 2010.
• Airbus Service Bulletin A320-55-1036, Revision 01, dated July 2, 2010.
• Airbus Service Bulletin A320-55-1037, Revision 01, dated July 2, 2010.
• Airbus Technical Disposition TD/K4/S2/27051/2009, Issue B, dated February 25, 2009.
• Airbus Technical Disposition TD/K4/S2/27086/2009, Issue E, dated September 17, 2009.

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.

Differences Between This AD and the MCAI or Service Information

This proposed AD requires the permanent restoration of vacuum loss holes and does not allow the temporary restoration with self-adhesive patches, or temporary restoration with resin that is specified in the MCAI.

Costs of Compliance

Based on the service information, we estimate that this proposed AD would affect about 721 products of U.S. registry.

The actions that are required by AD 2010-23-07, Amendment 39-16496 (75 FR 68181, November 5, 2010; corrected December 17, 2010 (75 FR 78883)), and retained in this proposed AD take about 11 work-hours per product, at an average labor rate of $85 per work hour. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the currently required actions on U.S. operators to be $674,135, or $935 per product.

We estimate that it would take about 11 work-hours per product to comply with the new basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $674,135, or $935 per product.

In addition, we estimate that any necessary follow-on actions would take about 12 work-hours and require parts costing $10,000, for a cost of $11,020 per product. We have no way of determining the number of products that may 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 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.

We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

We are issuing this AD to detect and correct extended de-bonding, which might degrade the structural integrity of the rudder. The loss of the rudder leads to degradation of the handling qualities and reduces the controllability of the airplane.

(f) Compliance

You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
