Federal Register Volume 80, Issue 247 (December 24, 2015)

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.

Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: 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.

DATES: This AD becomes effective January 28, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of January 28, 
2016.

SUPPLEMENTARY INFORMATION:

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 that this 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.

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.
