AD 2015-25-09

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, A330-200 Freighter, and A330-300 series airplanes; and all Model A340-200 and A340-300 series airplanes. This 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 AD requires 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 also provides an optional modification, which terminates the repetitive inspections. We are issuing 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.

Final rule.

Discussion

We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus Model A330- 200, A330-200 Freighter, and A330-300 series airplanes; and all Model A340-200 and A340-300 series airplanes. The NPRM published in the Federal Register on February 13, 2015 (80 FR 7989).
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,

[[Page 80240]]

and A330-300 series airplanes; and all Model 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/#!documentDetail;D=FAA-2015-0083-0002.

Comments

We gave the public the opportunity to participate in developing this AD. We have considered the comment received. The following presents the comment received on the NPRM (80 FR 7989, February 13, 2015) and the FAA's response.

Request To Identify Part Numbers in Paragraphs (g) and (h)

Delta Airlines requested that paragraphs (g) and (h) of the proposed AD (80 FR 7989, February 13, 2015) be revised to specify the part numbers of the affected brackets. Delta suggested that paragraph (g) of the proposed AD be revised to include the part number after the reference to bracket No. 6 (part number (P/N) F2511012820000, pre- modification Number 55128S18242; and P/N F2511373420000, post- modification Number 55128S18242). Delta also requested that paragraph (h)(2) of the proposed AD be revised to include the part number after bracket No. 6 (P/N F2511012820000, pre-modification Number 55128S18242; and P/N F2511373420000, post-modification Number 55128S18242) and bracket No. 7 (P/N F2511012820000, pre-modification Number 55128S18242; and P/N F2511373420000, post-modification Number 55128S18242). Delta stated that Airbus Service Bulletin A330-25-3538, Revision 02, dated April 24, 2014, specifies to inspect only P/N F2511012820000, pre- modification Number 55128S18242, and P/N F2511373420000, post- modification Number 55128S18242, and identifies only those part numbers as ``affected'' brackets that are used on both bracket No. 6 and bracket No. 7.
We agree to include the part numbers identified by the commenter in paragraphs (g) and (h)(2) of this AD. We have also included the part numbers in paragraphs (h)(1) and (h)(2)(i) of this AD. The ``Reason/ Description/Operational Consequences'' section of Airbus Service Bulletin A330-25-3538, Revision 02, dated April 24, 2014, specifies to inspect P/N F2511012820000, pre-modification Number 55128S18242, and P/ N F2511373420000, post-modification Number 55128S18242. Also, the Accomplishment Instructions of that service bulletin specify to replace P/N F2511012820000 or P/N F2511373420000, as applicable. We contacted Airbus for verification that only those part numbers are considered to be ``affected'' brackets and Airbus confirmed that only those part numbers are affected. The same affected and replacement parts are used on both Airbus Model A330-200, A330-200 Freighter, and A330-300 series airplanes; and A340-200 and A340-300 series airplanes.

Additional Change to This AD

A typographical error in paragraph (c)(1) of the proposed AD (80 FR 7989, February 13, 2015) has been corrected in this final rule. Paragraph (c)(1) of the proposed AD inadvertently included Model A330- 313 airplanes instead of Model A330-343 airplanes. The SUMMARY section and preamble of the NPRM stated that the applicability included Model A330-300 series airplanes, which include Model A330-343 airplanes.

Conclusion

We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this AD with the changes described previously and minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM (80 FR 7989, February 13, 2015) for correcting the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM (80 FR 7989, February 13, 2015).
We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD.

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 replacement of cockpit instrument panel bracket 6 with a reinforced titanium bracket.
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 replacement of cockpit instrument panel bracket 6 with a reinforced titanium bracket.
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.

Costs of Compliance

We estimate thatthis AD affects 76 airplanes of U.S. registry.
We also estimate that it will take about 8 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 $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 replacements will 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 will take about 9 work hours and require parts costing $1,770, for a cost of $2,535.

[[Page 80241]]

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 ofpower 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.
