# AGENCY:

Federal Aviation Administration (FAA), DOT.

# ACTION:

Notice of proposed rulemaking (NPRM).

# SUMMARY:

We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200, A330-200 Freighter, and A330-300 series airplanes; and all A340-200 and A340-300 series airplanes. This proposed AD was prompted by reports that a bracket that attaches the cockpit instrument panel to the airplane structure, does not sustain the fatigue loads of the design service goal. This proposed AD would require repetitive inspections of that bracket for cracking and to determine if both lugs are fully broken, an inspection for cracking of an adjacent bracket, if necessary, and corrective actions if necessary. This AD would also provide an optional modification, which would terminate the repetitive inspections. We are proposing this AD to detect and correct cracking on a bracket of the cockpit instrument panel, which, combined with failure of the horizontal beam, could lead to collapse of the cockpit panel, and reduced controllability of the airplane.

# DATES:

We must receive comments on this proposed AD by March 30, 2015.

## Discussion

The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014-0127, dated May 15, 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, A330-200 Freighter, and A330-300 series airplanes; and all A340-200, and A340-300 series airplanes. The MCAI states:

During flight tests, high stress levels have been measured on the bracket No 6 which attaches the cockpit instrument panel to the aeroplane structure, apparently introduced through the nose landing gear due to bumps on the runway. Airbus determined that the bracket does not sustain the fatigue loads during the Design Service Goal (DSG). This condition, if not detected and corrected, combined with failure of the horizontal beam, could lead to collapse of the cockpit panel, possibly resulting in reduced control of the aeroplane.

To address this potential unsafe condition, Airbus developed a program to inspect the condition of the affected cockpit instrument panel bracket No 6, and designed a stronger (reinforced titanium undrilled) bracket. The new bracket can be installed in-service through Airbus Service Bulletin (SB) A330-25-3548 or SB A340-25-4354, as applicable to aeroplane type.

For the reasons described above, this [EASA] AD requires repetitive inspections of the cockpit instrument panel bracket No 6 and, depending on findings, the accomplishment of applicable corrective actions. This [EASA] AD also provides the installation of the stronger bracket as optional terminating action for the repetitive actions required by this [EASA] AD. 

The corrective actions include replacing bracket No. 6 and bracket No. 7 with serviceable parts, and repair, as applicable.

                    You may examine the MCAI in the AD docket on the Internet at                     *http://www.regulations.gov*                     by searching for and locating Docket No. FAA-2015-0083.                          ( print page 7990)    

## Related Service Information Under 1 CFR Part 51

Airbus has issued the following service information.
    - Airbus Service Bulletin A330-25-3538, Revision 02, dated April 24, 2014, which provides procedures for inspection of cockpit instrument panel bracket 6.
    - Airbus Service Bulletin A330-25-3548, dated October 31, 2013, which provides procedures for reinforcement of cockpit instrument panel bracket 6.
    - Airbus Service Bulletin A340-25-4351, Revision 01, dated January 31, 2014, which provides procedures for inspection of cockpit instrument panel bracket 6.
    - Airbus Service Bulletin A340-25-4354, dated October 31, 2013, which provides procedures for reinforcement of cockpit instrument panel bracket 6.

                    The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. This service information is reasonably available; see                     **ADDRESSES**                     for ways to access this service information.                

## 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 these same type designs.

## Explanation of “RC” Procedures and Tests in Service Information

The FAA worked in conjunction with industry, under the Airworthiness Directives Implementation Aviation Rulemaking Committee (AD ARC), to enhance the AD system. One enhancement was a new process for annotating which procedures and tests in the service information are required for compliance with an AD. Differentiating these procedures and tests from other tasks in the service information is expected to improve an owner's/operator's understanding of crucial AD requirements and help provide consistent judgment in AD compliance. The actions specified in Airbus Service Bulletin A330-25-3538, Revision 02, dated April 24, 2014; and Airbus Service Bulletin A340-25-4351, Revision 01, dated January 31, 2014; include procedures and tests that are identified as RC (required for compliance) because these procedures have a direct effect on detecting, preventing, resolving, or eliminating an identified unsafe condition.

As specified in a NOTE under the Accomplishment Instructions of the specified service information, procedures and tests identified as RC must be done to comply with the proposed AD. However, procedures and tests that are not identified as RC are recommended. Those procedures and tests that are not identified as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program without obtaining approval of an alternative method of compliance (AMOC), provided the procedures and tests identified as RC can be done and the airplane can be put back in a serviceable condition. Any substitutions or changes to procedures or tests identified as RC will require approval of an AMOC.

## Costs of Compliance

We estimate that this proposed AD affects 76 airplanes of U.S. registry.

We also estimate that it would take about 8 work-hours 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 $51,680, or $680 per product.

We have received no definitive data that would enable us to provide cost estimates for the follow-on repairs specified in this AD.

In addition, we estimate that any necessary follow-on replacements would take about 23 work-hours and require parts costing $0, for a cost of $1,955 per product. We have no way of determining the number of aircraft that might need these actions.

We estimate that the optional modification would take about 9 work hours and require parts costing $1,770, for a cost of $2,535.

## 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.
