Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus Model A330-200 Freighter, -200, and -300 series airplanes. This 
proposed AD was prompted by a report of a manufacturing defect that 
affects the durability of affected parts in the cargo and cabin 
compartment. This proposed AD would require an inspection of affected 
structural parts in the cargo and cabin compartments to determine if 
proper heat-treatment has been done, and replacement if necessary. We 
are proposing this AD to prevent crack initiation and propagation, 
which could result in reduced structural integrity of the fuselage.

DATES: We must receive comments on this proposed AD by May 27, 2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent

[[Page 21487]]

for the Member States of the European Union, has issued European 
Airworthiness Directive 2015-0212, dated November 4, 2015, to correct 
an unsafe condition for all Airbus Model A330-200 Freighter, -200, and 
-300 series airplanes. The MCAI states:

    Airbus quality controls identified that several structural 
parts, intended for cargo or cabin compartment installation, were 
manufactured from improperly heat-treated materials. Subsequent 
review identified that some of those parts were installed on 
airplanes manufactured between November 2011 and February 2013. From 
February 2013, Airbus implemented measures into manufacturing 
processes to ensure detection and to prevent installation of such 
non-conforming parts.
    A detailed safety assessment was accomplished to identify the 
possible impact of affected parts on the airplane structure. The 
result of this structural analysis demonstrated the capability of 
the affected structure to sustain static limit loads, but failed to 
confirm that the affected structures met the certified fatigue life.
    This condition, if not detected and corrected, could lead to 
crack initiation and propagation, possibly resulting in reduced 
structural integrity of the fuselage.
    To address this potentially unsafe condition, Airbus issued 
[Mandatory] Service Bulletin (SB) SB A330-53-3227 and SB A330-53-
3228 to provide inspection instructions for affected cargo and cabin 
structural parts respectively.
    For the reasons described above, this [EASA] AD requires a one-
time Special Detailed Inspection (SDI) [eddy current inspection] to 
measure the electrical conductivity of affected structural parts, to 
identify the presence or absence of heat treatment, and, depending 
on findings, corrective action [replacement].

    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-
5460.

Related Service Information Under 1 CFR Part 51

    Airbus has issued the following service information:
     Airbus Mandatory Service Bulletin A330-53-3227, dated 
August 18, 2015. The service information describes procedures to 
inspect affected structural parts in the cargo compartment to determine 
if proper heat-treatment has been done, and replacement of parts; and
     Airbus Mandatory Service Bulletin A330-53-3228, dated 
August 18, 2015. The service information describes procedures to 
inspect affected structural parts in the cabin compartment to determine 
if proper heat-treatment has been done, and replacement of parts.
    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.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Differences Between This Proposed AD and the Service Information

    Figure A-GFAAA, Sheet 01, ``Inspection Flowchart,'' of Airbus 
Mandatory Service Bulletin A330-53-3227, dated August 18, 2015; and 
Figure A-GFAAA, Sheet 01, ``Inspection Flowchart'' of Airbus Mandatory 
Service Bulletin A330-53-3228, dated August 18, 2015, note that if any 
other measured (conductivity) value is found, to check the non-
destructive test (NDT) tool and perform a new measurement; and if that 
measured value is confirmed, contact Airbus for further instructions. 
This proposed AD would require that if a measured value is confirmed 
that is outside the measurements specified in the service information, 
a repair must be done using a method approved by the Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA; or 
EASA; or Airbus's EASA Design Organization Approval (DOA).

Costs of Compliance

    We estimate that this proposed AD affects 20 airplanes of U.S. 
registry.
    We also estimate that it will take about 11 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $18,700, or $935 
per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 45 work-hours for a cost of $3,825 per product. We have 
received no definitive data that would enable us to provide cost of the 
parts for the on-condition actions specified in this proposed AD. We 
have no way of determining the number of aircraft that might need this 
action.
    According to the manufacturer, some of the costs of this proposed 
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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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.
