14 CFR Part 39

[Docket No. FAA-2011-0918; Directorate Identifier 2011-NM-090-AD]
RIN 2120-AA64

Airworthiness Directives; Airbus Model A330-200 and -300 Series 
Airplanes; Model A340-200 and -300 Series Airplanes; Model A340-500 and 
-600 Series Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for the 
products listed above. This proposed AD results from mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of another country to identify and correct an unsafe 
condition on an aviation product. The MCAI describes the unsafe 
condition as:

    During a pre-flight test before delivery of an aeroplane from 
the Airbus production line, a fault message was triggered on FDU1 
[fire detection unit].
    Investigations by the supplier on the faulty FDU have identified 
a soldering quality issue on one of the internal cards. This quality 
issue resulted from a specific repair process that was applied to 
some FDU * * * during manufacturing.
    The FDU monitors the engine, Auxiliary Power Unit (APU) and Main 
Landing Gear (MLG) bay fire detection systems.
    This condition, if not corrected, may adversely affect the fire 
detection system performance in case of a fire in the area that is 
monitored by the faulty FDU, potentially resulting in an unsafe 
condition.
* * * * *
The proposed AD would require actions that are intended to address the 
unsafe condition described in the MCAI.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2011-0073, dated April 20, 2011 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    During a pre-flight test before delivery of an aeroplane from 
the Airbus production line, a fault message was triggered on FDU1.
    Investigations by the supplier on the faulty FDU have identified 
a soldering quality issue on one of the internal cards. This quality 
issue resulted from a specific repair process that was applied to 
some FDU Part Number (P/N) 3711-00 during manufacturing.
    The FDU monitors the engine, Auxiliary Power Unit (APU) and Main 
Landing Gear (MLG) bay fire detection systems.
    This condition, if not corrected, may adversely affect the fire 
detection system performance in case of a fire in the area that is 
monitored by the faulty FDU, potentially resulting in an unsafe 
condition.
    For the reasons described above, this [EASA] AD requires the 
identification and replacement of the affected FDU.

You may obtain further information by examining the MCAI in the AD 
docket.

The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

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 AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a Note within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 58 products of U.S. registry. We also estimate that 
it would take about 1 work-hour per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Required parts would cost about $0 per product. Replacement 
parts may be provided free of charge by the manufacturer. Where the 
service information lists required parts costs that are covered under 
warranty, we have assumed that there will be no charge for these parts. 
As we do not control warranty coverage for affected parties, some 
parties may incur costs higher than estimated here. Based on these 
figures, we estimate the cost of the proposed AD on U.S. operators to 
be $4,930, or $85 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 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); and
    3. 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

    2. The FAA amends Sec.  39.13 by adding the following new AD:

Airbus: Docket No. FAA-2011-0918; Directorate Identifier 2011-NM-
090-AD.

Comments Due Date

    (a) We must receive comments by October 31, 2011.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Airbus Model A330-201, -202, -203, -223, 
-223F, -243, and -243F airplanes; Model A330-301, -302, -303, -321, 
-322, -323, -341, -342, and -343 airplanes; Model A340-211, -212, 
and -213 airplanes; Model A340-311, -312, and -313 airplanes; Model 
A340-541 airplanes; and Model A340-642 airplanes; certificated in 
any category; all serial numbers.

Subject

    (d) Air Transport Association (ATA) of America Code 26: Fire 
Protection.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    During a pre-flight test before delivery of an aeroplane from 
the Airbus production line, a fault message was triggered on FDU1 
[fire detection unit].
    Investigations by the supplier on the faulty FDU have identified 
a soldering quality issue on one of the internal cards. This quality 
issue resulted from a specific repair process that was applied to 
some FDU * * * during manufacturing.
    The FDU monitors the engine, Auxiliary Power Unit (APU) and Main 
Landing Gear (MLG) bay fire detection systems.
    This condition, if not corrected, may adversely affect the fire 
detection system performance in case of a fire in the area that is 
monitored by the faulty FDU, potentially resulting in an unsafe 
condition.
* * * * *

Compliance

    (f) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Actions

    (g) Within 1,000 flight hours after the effective date of this 
AD: Do an inspection to identify the Fire Detection Unit (FDU) part 
number (P/N) and serial number (S/N) of each engine, auxiliary power 
unit (APU), and MLG bay (for Model A340-500 and -600 series 
airplanes only), as applicable, in accordance with the instructions 
of Airbus All Operators Telex (AOT) A330-26A3052, dated April 19, 
2011 (for Model A330-200 and -300 series airplanes); Airbus AOT 
A340-200/300-26A4044, dated April 19, 2011 (for Model A340-200 and -

April 19, 2011 (for Model A340-500 and -600 series airplanes). A 
review of maintenance records is acceptable in lieu of this 
inspection if the P/N and S/N of the installed FDU can be 
conclusively determined from that review.
    (h) If during the inspection required by paragraph (g) of this 
AD, P/N 3711-00 FDU

[[Page 56682]]

is found installed and the S/N of the FDU is listed in table 1 of 
this AD: Before further flight, replace the FDU with a serviceable 
FDU, in accordance with the instructions of Airbus AOT A330-26A3052, 
dated April 19, 2011 (for Model A330-200 and -300 series airplanes);
