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 receipt of spare parts at the final assembly line, it was 
discovered that lugs of the assembly nut * * * had been inverted 
(wrong orientation of the braking pin) during manufacturing process 
at the supplier.
    * * * This lug inversion could give the illusion of correct 
torque whereas the affected parts are not properly connected.
    Loose connection could lead to loss of the fire extinguishing 
system integrity and therefore inability to ensure the adequate 
agent concentration. In combination with an engine fire event, it 
could result in a temporary uncontrolled engine fire, which 
constitutes an unsafe condition.

* * * * *
    The proposed AD would require actions that are intended to address 
the unsafe condition described in the MCAI.

DATES: We must receive comments on this proposed AD by April 27, 2009.

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 2008-0196, dated October 27, 2008 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    During receipt of spare parts at the final assembly line, it was 
discovered that lugs of the assembly nut, part number (P/N) 
A2621005000200, had been inverted (wrong orientation of the braking 
pin) during manufacturing process at the supplier.
    The assembly nut P/N A2621005000200 is part of the engine fire-
extinguishing piping assembly. It connects the extinguisher 
discharge head with the piping. The lugs function is to prevent the 
connection untwisting once it has been hand-tightened with the 
correct torque. This lug inversion could give the illusion of 
correct torque whereas the affected parts are not properly 
connected.
    Loose connection could lead to loss of the fire extinguishing 
system integrity and therefore inability to ensure the adequate 
agent concentration. In combination with an engine fire event, it 
could result in a temporary uncontrolled engine fire, which 
constitutes an unsafe condition.
    To restore connection integrity, this Airworthiness Directive 
(AD) requires a one-time general visual inspection of the affected 
nut assembly to detect and correct any wrong orientation of lugs.

    The corrective actions include a temporary repair (restoration) and 
replacing the fire extinguisher bottle nut assembly with the braking 
pin in the inverted position, if necessary.
    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletin A330-26-3043, 
including Appendices 01, 2, and 3, dated October 7, 2008. 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 4 products of U.S. registry. We also estimate that 
it would take about 9 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $2,880, or $720 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

[[Page 13146]]

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.

Subject

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

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:
    During receipt of spare parts at the final assembly line, it was 
discovered that lugs of the assembly nut, part number (P/N) 
A2621005000200, had been inverted (wrong orientation of the braking 
pin) during manufacturing process at the supplier.
    The assembly nut P/N A2621005000200 is part of the engine fire-
extinguishing piping assembly. It connects the extinguisher 
discharge head with the piping. The lugs function is to prevent the 
connection untwisting once it has been hand-tightened with the 
correct torque. This lug inversion could give the illusion of 
correct torque whereas the affected parts are not properly 
connected.
    Loose connection could lead to loss of the fire extinguishing 
system integrity and therefore inability to ensure the adequate 
agent concentration. In combination with an engine fire event, it 
could result in a temporary uncontrolled engine fire, which 
constitutes an unsafe condition.
    To restore connection integrity, this Airworthiness Directive 
(AD) requires a one-time general visual inspection of the affected 
nut assembly to detect and correct any wrong orientation of lugs.
    The corrective actions include a temporary repair (restoration) 
and replacing the fire extinguisher bottle nut assembly with the 
braking pin in the inverted position, if necessary.

Actions and Compliance

    (f) Unless already done, do the following actions:
    (1) Within 900 flight hours after the effective date of this AD, 
perform a general visual inspection to detect any wrong orientation 
of the lugs of the fire extinguisher bottle nut assembly of both 
engines, and do all applicable corrective actions specified in 
paragraphs (f)(1)(i) and (f)(1)(ii) of this AD, in accordance with 
the Accomplishment Instructions of Airbus Mandatory Service Bulletin 
A330-26-3043, dated October 7, 2008.
    (i) Before further flight, if the correct nut assembly is 
available, replace the fire extinguisher bottle nut assembly.
    (ii) Before further flight, if the correct nut assembly is not 
available, do the temporary repair; and within 900 flight hours 
after doing the repair, replace the fire extinguisher bottle nut 
assembly with the correct one.
    (2) Submit a report of the findings of the inspection required 
by paragraph (f)(1) of this AD using Appendix 01 of Airbus Mandatory 
Service Bulletin A330-26-3043, dated October 7, 2008, at the 
applicable time specified in paragraph (f)(2)(i) or (f)(2)(ii) of 
this AD. Send the report to Airbus Department SEEE6, Airbus Customer 
Services Directorate, 1 Rond Point Maurice Bellonte, 31707 Blagnac 
Cedex France, ATTN: SDC32 Technical Data and Documentation Services; 
fax: 33 5 61 93 28 06; e-mail: sb.reporting@airbus.com.
    (i) If the inspection was done on or after the effective date of 
this AD: Submit the report within 30 days after the inspection.
    (ii) If the inspection was accomplished prior to the effective 
date of this AD: Submit the report within 30 days after the 
effective date of this AD.

FAA AD Differences

    Note 1: This AD differs from the MCAI and/or service information 
as follows: No differences.
