Airworthiness Directives; Airbus Model A330-200, A330-300, A340-
200, and A340-300 Series Airplanes; and Model A340-541 and A340-642 
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
Airbus Model A330-200, A330-300, A340-200, and A340-300 series 
airplanes; and Model A340-541 and A340-642 airplanes. This AD requires 
an inspection for anti-fretting material contamination of the Halon 
filters and plumbing parts of the flow metering system (FMS) and flow 
metering compact unit (FMCU) in the lower deck cargo compartment (LDCC) 
and bulk crew rest compartment (BCRC), as applicable; other specified 
actions; and corrective actions if necessary. This AD results from a 
report that the FMS and FMCU of the fire extinguishing system may be 
blocked by anti-fretting material contamination. We are issuing this AD 
to prevent such anti-fretting material contamination, which could 
reduce the effectiveness of the fire extinguisher system to discharge 
fire extinguishing agents and to lower the concentration of Halon gas 
in the LDCC or BCRC in a timely manner. An ineffective fire 
extinguisher system in the event of a fire could result in an 
uncontrollable fire in the LDCC or BCRC.

DATES: This AD becomes effective July 27, 2006.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of July 27, 2006.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the airworthiness directive (AD) docket on the 
Internet at http://dms.dot.gov or in person at the Docket Management 
Facility office between 9 a.m. and 5 p.m., Monday through Friday, 
except Federal holidays. The Docket Management Facility office 
(telephone (800) 647-5227) is located on the plaza level of the Nassif 
Building at the street address stated in the ADDRESSES section.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to all Airbus Model A330-
200, A330-300, A340-200, and A340-300 series airplanes; and Model A340-
541 and A340-642 airplanes. That NPRM was published in the Federal 
Register on March 28, 2006 (71 FR 15354). That NPRM proposed to require 
an inspection for anti-fretting material contamination of the Halon 
filters and plumbing parts of the flow metering system (FMS) and flow 
metering compact unit (FMCU) in the lower deck cargo compartment (LDCC) 
and bulk crew rest compartment (BCRC), as applicable; other specified 
actions; and corrective actions if necessary.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments received.

Request To Revise the Applicability

    Airbus requests that Model A330-302 and -303 airplanes be included 
in the applicability of paragraph (c)(2) of the NPRM. Airbus states 
that those airplanes are in the process of being U.S. type 
certificated.
    We agree. We have determined that Model A330-302 and -303 airplanes 
are subject to the identified unsafe condition of this AD. Therefore, 
we have revised the applicability of paragraph (c)(2) and Table 2 and 3 
of this AD to include those airplanes to ensure that the identified 
unsafe condition is addressed if any of those affected airplanes are 
imported and placed on the U.S. Register in the future.

Request To Refer To Correct Modification Number

    Airbus requests that Airbus modification ``49316'' specified in 
paragraph (i)(1) of Table 4 of the NPRM be changed to ``49136.'' Airbus 
states Airbus modification 49316 addresses the landing gear and 
hydraulic hoses, which are not addressed by the NPRM, whereas Airbus 
modification 49136 addresses the BCRC, which is addressed by the NPRM.
    We agree and have revised paragraph (i)(1) of Table 4 of the AD 
accordingly.

Conclusion

    We have carefully reviewed the available data, including the 
comments received, and determined that air safety and the public 
interest require adopting the AD with the changes described previously. 
We have determined that these changes will neither increase the 
economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
to comply with this AD.

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 have 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 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 AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.

Unsafe Condition

    (d) This AD results from a report that the flow metering system 
(FMS) and the flow metering compact unit (FMCU) of the fire 
extinguishing system may be blocked by anti-fretting material 
contamination. We are issuing this AD to prevent such anti-fretting 
material contamination, which could reduce the effectiveness of the 
fire extinguisher system to discharge fire extinguishing agents and 
to lower the concentration of Halon gas in the lower deck cargo 
compartment (LDCC) and bulk crew rest compartment (BCRC) in a timely 
manner. An ineffective fire extinguisher system in the event of a 
fire could result in an uncontrollable fire in the LDCC or BCRC.

Compliance

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

Restoration

    (f) After the effective date of this AD, after any activation of 
the fire extinguishing system, before further flight, restore the 
fire extinguishing system in the LDCC and in the BCRC, as 
applicable, in accordance with a method approved by either the 
Manager, International Branch, ANM-116, Transport Airplane 
Directorate, FAA; or the Direction G[eacute]n[eacute]rale de 
l'Aviation Civile (or its delegated agent). The applicable airplane 
maintenance manual (AMM) in table 2 of this AD is one approved 
method, provided that the following caution note is included in the 
work instructions of that AMM:

``CAUTION: APPLY A SMALL QUANTITY OF THE CORRECT GREASE TO THE MALE 
THREADS OF THE CONNECTIONS. THIS WILL PREVENT DAMAGE TO THE THREADS. 
MAKE SURE THAT THE GREASE DOES NOT GO INTO THE PIPES. GREASE IN THE 
PIPES CAN CAUSE A MALFUNCTION OF THE SYSTEM.''
