Airworthiness Directives; Airbus Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding Airworthiness Directive (AD) 2014-03-14 for all Airbus Model A330-200 and -300 series airplanes, and Model A340-
200, -300, -500, and -600 series airplanes. AD 2014-03-14 required removing bulb-type maintenance lights; installing a drain mast on certain airplanes; and installing muffs on connecting bleed elements on certain airplanes. For certain Model A340-200 and -300 series airplanes, this new AD also requires replacing certain insulation sleeves with new insulation sleeves. This AD results from fuel system reviews conducted by the airplane manufacturer. We are issuing this AD to prevent ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2014-03-14, Amendment 39-17752 (79 FR 9382, February 19, 2014) (``AD 2014-03-14''). AD 2014-03-14 applied to all Airbus Model A330-200 and -300 series airplanes, and Model A340-200, -
300, -500, and -600 series airplanes. The NPRM published in the Federal Register on December 11, 2015 (80 FR 76875) (``the NPRM''). The NPRM was prompted by fuel system reviews conducted by the airplane manufacturer. The NPRM proposed to continue to require removing bulb-
type maintenance lights; installing a drain mast on certain airplanes; and installing muffs on connecting bleed elements on certain airplanes. The NPRM also proposed to require, for certain Model A340-200 and -300 series airplanes, replacing certain insulation sleeves with new insulation sleeves. We are issuing this AD to prevent ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014-0148, dated June 13, 2014 (referred to after this the Mandatory Continuing Airworthiness Information, or ``the MCAI''), to correct an unsafe condition for all Airbus Model A330-200 and -300 series airplanes, and Model A340-200, -300, -500, and -600 series airplanes. The MCAI states:
Subsequent to accidents involving Fuel Tank Systems in flight and on ground * * *, the FAA published Special Federal Aviation Regulation (SFAR) 88 (66 FR 23086, May 7, 2001), and the Joint Aviation Authorities (JAA) published Interim Policy INT/POL/25/12.
In response to these regulations, a global design review conducted by Airbus on the A330 and A340 type design Section 19, which is a flammable fluid leakage zone and a zone adjacent to a fuel tank, highlighted potential deviations. The specific identified cases were that in-flight fuel drainage is insufficient on A340-500/
-600 aeroplanes, maintenance lights are not qualified explosion-
proof, and hot surfaces may exist on bleed systems during normal/
failure operations.
Page 24460
This condition, if not corrected, in combination with a fuel leak generating flammable vapours in the area, could result in a fuel tank explosion and consequent loss of the aeroplane.
To address this unsafe condition, Airbus developed various modifications of the aeroplane, to be embodied in service.
Consequently, EASA issued AD 2013-0033 http://ad.easa.europa.eu/blob/easa_ad_2013-0033_superseded.pdf/AD_2013-0033_1, which corresponds to FAA AD 2014-03-14, Amendment 39-17752 (79 FR 9382, February 19, 2014) to require removal of bulb type maintenance lights for all aeroplanes, installation of a drain mast between Frame (FR) 80 and FR83 for A340-500/-600 aeroplanes, and installation of muffs on connecting bleed elements to minimize hot surfaces on A330 and A340-200/-300 aeroplanes.
Since that EASA AD was issued, it was reported that, for A340-
200/-300 aeroplanes, accomplishment instructions in the applicable Airbus Service Bulletins (SB) for aeroplanes in Configurations 002 and 005 were detailed in Configuration 003 and, conversely, accomplishment instructions for aeroplanes in Configuration 003 were detailed in Configurations 002 and 005. This can lead to incorrect installation of some insulation sleeves on the Auxiliary Power Unit (APU) Air Bleed Ducts between Frame 83 and 84 for configurations 002, 003 and 005 as per Airbus SB A340-36-4035 at original issue. Prompted by this finding, Airbus revised the affected SB with additional work required for aeroplanes included in configurations 002, 003 and 005 that were modified using the original issue of the SB.
For the reasons described above, this EASA AD retains the requirements of EASA AD 2013-0033, which is superseded, incorporates reference to the corrected Airbus SB A340-36-4035 Revision 01 and requires the additional work as specified in Airbus SB A340-36-4035 Revision 01 for aeroplanes already modified per the original SB A340-36-4035.
The additional work is replacing the insulation sleeves between FR83 and FR84 with new insulation sleeves. 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-2015-6547.
Comments
We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public.
Change Made To This Final Rule: Updated Service Information
Airbus has issued Service Bulletin A330-36-3038, Revision 01, dated May 11, 2015. The additional work specified in this service information is minimal and consists of modifying the routing of a harness. This additional work is not required for airplanes on which the actions previously required by paragraph (h) of AD 2014-03-14 have been done before the effective date of this AD. Paragraph (h) of this AD retains the requirements of paragraph (h) of AD 2014-03-14. We have revised paragraph (h)(1) of this AD to specify Airbus Service Bulletin A330-36-
3038, Revision 01, dated May 11, 2015, as an appropriate source of service information.
Conclusion
We reviewed the available data and determined that air safety and the public interest require adopting this AD with the change described previously and minor editorial changes. We have determined that these changes:
Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
Airbus has issued the following service bulletins.

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 43 Model A330 series airplanes of U.S. registry. There are no Model A340 airplanes registered in the U.S.
The actions required by AD 2014-03-14, and retained in this AD take about 21 work-hours per product, at an average labor rate of $85 per work-hour. Required parts cost about $5,219 per product. Based on these figures, the estimated cost of the actions that were required by AD 2014-03-14 is $7,004 per product.
We also estimate that it will take about 6 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $279 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $33,927, or $789 per product.
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
Page 24461
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.
