Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2015-0085; Directorate Identifier 2014-NM-078-AD; 
Amendment 39-18255; AD 2015-17-22]
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 all 
Airbus Model A330-243, A330-243F, A330-341, A330-342, and A330-343 
airplanes. This AD was prompted by reports indicating that certain 
hinge sleeves on the cowl doors of the thrust reverser units (TRUs) 
were not heat treated. This AD requires replacing the sleeves of 
certain hinges on the cowl doors of the TRUs with new parts. We are 
issuing this AD to prevent, in the event of a fan-blade-off event due 
to high vibration, in-flight loss of TRU heavy components, which might 
damage airplane structure or control surfaces and consequently reduce 
controllability of the airplane.

DATES: This AD becomes effective October 7, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 7, 
2015.

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 A330-243, 
A330-243F, A330-341, A330-342, and A330-343 airplanes. The NPRM 
published in the Federal Register on February 13, 2015 (80 FR 7986).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0062, dated March 11, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model 
A330-243, A330-243F, A330-341, A330-342, and A330-343 airplanes. The 
MCAI states:

    A manufacturing discrepancy (lack of heat treatment) on a batch 
of the N[deg]3 and N[deg]4 hinge sleeves installed on [a] Thrust 
Reverser Unit (TRU) was identified. Those parts are only installed 
on A330 aeroplanes equipped with Rolls-Royce (RR) Trent 700 engines.
    This condition, if not corrected, in case of a Fan Blade Off 
event due to high vibration level, could cause in-flight loss of 
some heavy components of the TRU, possibly resulting in injury to 
persons on the ground [or damage to airplane structure or control 
surfaces, and consequent reduced controllability of the airplane].
    As current hinge sleeves are not serialized, it is not possible 
to identify the TRU hinge sleeves which did not receive the heat 
treatment. The part supplier has developed an identification 
procedure for these TRU hinge sleeves in order to identify the 
affected hinge sleeves, and to allow a better part traceability in 
the future.
    For the reason described above, this [EASA] AD requires 
identification and replacement of the affected TRU hinge sleeves.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2015-0085-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 7986, February 13, 
2015) or on the determination of the cost to the public.

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:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (80 FR 7986, February 13, 2015) for correcting the unsafe 
condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 7986, February 13, 2015).

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A330-78-3021, Revision 03, dated 
October 15, 2014. Aircelle has issued Service Bulletin 78-AG924, dated 
September 26, 2012. This service information describes procedures for 
modifying and marking the sleeves for hinges number 3 and number 4 on 
the cowl doors of Rolls-Royce Trent 700 engines. 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 of this AD.

[[Page 52936]]

Costs of Compliance

    We estimate that this AD affects 24 airplanes of U.S. registry.
    We also estimate that it will take about 29 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 $0 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $59,160, or $2,465 per product.
    In addition, we estimate that any necessary follow-on action will 
take up to 1 work-hour and require parts costing $0, for a cost of $85 
per product. We have no way of determining the number of aircraft that 
might need this action.

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.
