Airworthiness Directives; Airbus Airplanes
AGENCY:
Federal Aviation Administration (FAA), Department of Transportation (DOT).
ACTION:
Final rule.
SUMMARY:
We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200 and -300 series airplanes, and Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by results from fuel system reviews conducted by the airplane manufacturer. This AD requires removing bulb-type maintenance lights; installing a drain mast on certain airplanes; and installing muffs on connecting bleed elements on certain airplanes. 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.
DATES:
This AD becomes effective March 26, 2014.
The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of March 26, 2014.

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 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 July 31, 2013 (78 FR 46306). The NPRM was prompted by results from fuel system reviews conducted by the airplane manufacturer. The NPRM proposed to require removing bulb-type maintenance lights; installing a drain mast on certain airplanes; and installing muffs on connecting bleed elements on certain airplanes. 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 Community, has issued EASA Airworthiness Directive 2013-0033, dated February 19, 2013 (referred to after this the Mandatory Continuing Airworthiness Information, or "the MCAI"), to correct an unsafe condition for the specified products. The MCAI states:
[Subsequent to accidents involving fuel tank system explosions in flight and on ground], the FAA published Special Federal Aviation Regulation (SFAR) 88 [66FR 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 drainage is inefficient in flight on A340-500/-600 aeroplanes, maintenance lights are not qualified explosion proof, and hot surfaces may exist on bleed system during normal/failure operations.
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.
For the reasons described above, this [EASA] AD requires removal of bulb type maintenance lights for all aeroplanes, installation of the drain mast between Frame (FR) 80 and FR83 for A340-500/-600, and installation of muffs on connecting bleed elements to minimize hot surfaces on A330 and A340-200/-300.
You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2013-0632-0002.
Comments
We gave the public the opportunity to participate in developing this AD. We have considered the comments received. The following presents the comments received on the proposal (78 FR 46306, July 31, 2013) and the FAA's response to each comment.
Request To Require New Service Information
[top] Airbus requested that we specify the use of Revision 01 of Airbus Mandatory Service Bulletin A340-36-4035, dated September 24, 2013, instead of the original issue of Airbus Mandatory Service Bulletin A340-36-4035, dated September 18, 2012. Airbus stated that since the issuance of the MCAI, it identified an inversion of configurations in Airbus Mandatory Service Bulletin A340-36-4035. Airbus stated that it
We agree with the commenter. Airbus Mandatory Service Bulletin A340-36-4035, Revision 01, dated September 24, 2013, introduces corrections to part numbers for two insulation sleeves between frames 83 and 84 in configurations 002, 003, and 005. This revision also adds an additional work task for configurations 002, 003, and 005 to replace two insulation sleeves between frame 83 and 84, and changes the insulation sleeves kit allocation for configurations 002, 003, and 005 to allocate the correct kit to every configuration.
Even though Airbus Mandatory Service Bulletin A340-36-4035, Revision 01, dated September 24, 2013, introduces additional work it does not affect United States operators since there are no Model A340 airplanes registered in the United States.
We have changed paragraph (h) of this final rule to reference Airbus Mandatory Service Bulletin A340-36-4035, Revision 01, dated September 24, 2013.
Request To Reference Certain Service Bulletins
Airbus noted that we reference Airbus Service Bulletin A340-33-5007 in Note 1 to paragraph (g) of the NPRM (78 FR 46306, July 31, 2013). Airbus stated that it is working on the issuance of equivalent service bulletins, and requested that we reference these service bulletins.
We disagree with the commenter's request. The referenced service information is not available. To delay this action would be inappropriate, since we have determined that an unsafe condition exists and that actions specified in this final rule must be conducted to ensure continued safety. We might consider additional rulemaking when new service information is made available. We have not changed this final rule in this regard.
Request To Remove Certain Credit for Previous Actions
Airbus requested that we remove the credit given for actions accomplished in accordance with Airbus Service Bulletin A330-36-3037, dated September 23, 2011, which is referenced in paragraph (k)(3) of the NPRM (78 FR 46306, July 31, 2013). Airbus stated that it was on purpose that no credit was provided in the MCAI for this service bulletin.
We agree with the commenter's request. Airbus Service Bulletin A330-36-3037, Revision 01, dated January 24, 2013, introduces corrections to accomplish certain procedures that are used to comply with the intent of this final rule. We have removed the reference to Airbus Service Bulletin A330-36-3037, dated September 23, 2011, in paragraph (k)(3) of this final rule.
Request To Use Alternative Materials
Delta Airlines (DAL) requested that we provide authorization to use alternative materials to those listed in Airbus Mandatory Service Bulletin A330-33-3041, Revision 01, dated July 10, 2012: and Airbus Mandatory Service Bulletin A330-36-3040, Revision 01, dated November 26, 2012. DAL stated that it cannot acquire certain materials, and suggested certain alternative materials.
We disagree with the commenter's request. The use of the alternative materials proposed by the commenter to those listed in Airbus Mandatory Service Bulletin A330-33-3041, Revision 01, dated July 10, 2012; and Airbus Mandatory Service Bulletin A330-36-3040, Revision 01, dated November 26, 2012; is not authorized by the airplane manufacturer. Under the provisions of paragraph (l) of this final rule, however, we will consider requests for approval of use of other materials as alternative methods of compliance. We have not changed this final rule in this regard.
Conclusion
We reviewed the available data, including the comments 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 changes:
• Are consistent with the intent that was proposed in the NPRM (78 FR 46306, July 31, 2013) for correcting the unsafe condition; and
• Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 46306, July 31, 2013).
Costs of Compliance
We estimate that this AD affects 43 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
| Action | Labor cost | Parts cost | Cost per product | Cost on U.S. operators |
|---|---|---|---|---|
| Installation | Up to 21 work-hours × $85 per hour = $1,785 | Up to $5,219 | Up to $7,004 | Up to $301,172. |
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;
[top] 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.
