Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2016-3988; Directorate Identifier 2015-NM-130-AD; 
Amendment 39-18546; AD 2016-11-19]
RIN 2120-AA64


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 certain 
Airbus Model A330-200, -200 Freighter, and -300 series airplanes; and 
all Airbus Model A340-200, -300, -500, and -600 series airplanes. This 
AD was prompted by reports of chafing of the feeder cable at the pylon-
wing junction due to vibration; one report revealed that the cable loom 
plastic support bracket of the G-route was broken due to vibration; and 
another report revealed wire chafing due to clamp damage. This AD 
requires modifying the cable loom support bracket of the G-route of the 
inboard pylons at the pylon-wing junction. We are issuing this AD to 
prevent chafing of the wiring in the pylon-wing area, which could 
result in an electrical short circuit near a flammable fluid vapor 
zone, and consequent fire or fuel tank explosion.

DATES: This AD is effective July 22, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of July 22, 
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, -200 Freighter, and -300 series airplanes; and all Airbus Model 
A340-200, -300, -500, and -600 series airplanes. The NPRM published in 
the Federal Register on March 1, 2016 (81 FR 10549) (``the NPRM''). The 
NPRM was prompted by reports of chafing of the feeder cable at the 
pylon-wing junction due to vibration; one report revealed that the 
cable loom plastic support bracket of the G-route was broken due to 
vibration; and another report revealed wire chafing due to clamp 
damage. The NPRM proposed to require modifying the cable loom support 
bracket of the G-route of the inboard pylons at the pylon-wing 
junction. We are issuing this AD to prevent chafing of the wiring in 
the pylon-wing area, which could result in an electrical short circuit 
near a flammable fluid vapor zone, and consequent fire or fuel tank 
explosion.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2015-0142, dated July 17, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A330-200, -200 Freighter, and -300 series airplanes; and all Airbus 
Model A340-200, -300, -500, and -600 series airplanes. The MCAI states:

    Two events have been reported of feeder cable chafing at the 
pylon-wing junction on A330 aeroplanes. Inspection of the affected 
area for the first event revealed that the bracket supporting the 
cables G-route, made in plastic, was broken. The second event was 
due to clamp damage. Failure of support bracket and/or damage of 
clamp led to the feeder cables gradually chafing away at the cut-out 
edge by vibration. Due to design similarity, A340 aeroplanes are 
also affected by this issue.
    This condition, if not corrected, could create a short circuit, 
in combination with fuel vapour on [the] ground, possibly resulting 
in a fire or explosion.
    To address this unsafe condition, Airbus developed modifications 
to be embodied in service through Airbus Service Bulletin (SB) A330-
92-3132, SB A340-92-4100 or SB A340-92-5066, as applicable to 
aeroplane type and model.
    For the reasons described above, this [EASA] AD requires the 
embodiment of these modifications [of the cable loom support bracket 
of the G-route of the inboard pylons] at the pylon/wing junction in 
[left-hand] LH and [right-hand] RH wings.

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-2016-
3988.

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.

[[Page 39542]]

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed, except for 
minor editorial changes. We have determined that these minor 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

    We reviewed the following Airbus service information:
     Service Bulletin A330-92-3132, Revision 01, dated May 21, 
2015.
     Service Bulletin A340-92-4100, Revision 01, dated May 21, 
2015.
     Service Bulletin A340-92-5066, dated June 25, 2014.
    This service information describes procedures for modifying the 
cable loom support bracket of the G-route of the inboard pylons at the 
pylon-wing junction. 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 90 airplanes of U.S. registry.
    We also estimate that it takes about 8 work-hours per product to 
comply with the modification requirements of this AD. Required parts 
will cost about $900 per product. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost for the 
inspection specified in this AD on U.S. operators to be $142,200, or 
$1,580 per product.
    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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.
