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.''
