ACTION: Notice of proposed rulemaking (NPRM). dsatterwhite on PROD1PC76 with PROPOSALS AGENCY: The FAA proposes to adopt 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 proposed AD SUMMARY: VerDate Aug<31>2005 15:43 Mar 27, 2006 Jkt 208001 would require an inspection for antifretting 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 proposed 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 proposing 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: We must receive comments on this proposed AD by April 27, 2006.

Discussion ´ ´ The Direction Generale de l’Aviation Civile (DGAC), which is the airworthiness authority for France, notified us that an unsafe condition may exist on all Airbus Model A330–200, A330–300, A340–200, and A340–300 series airplanes; and Model A340–541 and A340–642 airplanes. The DGAC advises that the flow metering system (FMS) and the flow metering compact unit (FMCU) (only on Model A340–200 and –300 series airplanes, and Model A340–541 and A340–642 airplanes) of the fire extinguishing system may be blocked by anti-fretting material contamination. The origin of this antifretting material contamination inside the piping, filters, and pressure reducers may come from manufacturing of the parts, as well as installation on airplanes during production or maintenance. After the first activation of the fire extinguishing system, the DGAC advises to assume that the FMS or FMCU is contaminated, and that the fire E:\FR\FM\28MRP1.SGM 28MRP1 Federal Register / Vol. 71, No. 59 / Tuesday, March 28, 2006 / Proposed Rules extinguishing system may not be fully operable for its next use. Anti-fretting material contamination, if not corrected, 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) or bulk crew rest compartment (BCRC) in a timely manner. An ineffective fire extinguisher system in the event of a fire could result 15355 in an uncontrollable fire in the LDCC or BCRC.

The DGAC mandated the service information and issued French airworthiness directives F–2005–019 R1 (for Model A330–200 and A330–300 series airplanes), and F–2005–020 R1 (for Model A340–200 and A340–300 series airplanes, and Model A340–541 E:\FR\FM\28MRP1.SGM 28MRP1 15356 Federal Register / Vol. 71, No. 59 / Tuesday, March 28, 2006 / Proposed Rules and A340–642 airplanes); both dated May 11, 2005; to ensure the continued airworthiness of these airplanes in France. FAA’s Determination and Requirements of the Proposed AD These airplane models are manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DGAC has kept the FAA informed of the situation described above. We have examined the DGAC’s findings, evaluated all pertinent information, and determined that we need to issue an AD for airplanes of this type design that are certificated for operation in the United States. Therefore, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously. Clarification Between the Proposed AD and French Airworthiness Directives The French airworthiness directives specify the following compliance times for inspecting the FMCU and FMS in the LDCC: COMPLIANCE TIMES IN FRENCH AIRWORTHINESS DIRECTIVES For airplanes— Compliance time On which the fire extinguishing system is confirmed to have never been activated. On which the fire extinguishing system has been activated at least once or it is uncertain whether it has ever been activated or not. Like the French airworthiness directive, the proposed AD would require all affected airplanes to do the proposed actions within 2,400 flight hours after the effective date of the AD or within 6,600 flight hours after the effective date of the AD if an operator can conclusively determine that the fire extinguishing system has never been activated. However, the French airworthiness directive does not specify Within 6,600 flight hours after the effective date of the AD. Within 2,400 flight hours after the effective date of the AD. the means of making that determination. We have determined that reviewing an airplane log book is not a reliable way to determine if a fire extinguishing bottle has been activated, and that the only means of making this determination is by reviewing the airplane maintenance records. Therefore, this proposed AD would allow the proposed inspections to be done within 6,600 flight hours after the effective date of this AD, provided that reviewing the airplane maintenance records can conclusively determine that the fire extinguishing system has never been activated before the effective date of this AD. Costs of Compliance The following table provides the estimated costs for U.S. operators to comply with this proposed AD. ESTIMATED COSTS Average labor rate per hour Work hours Inspection and restoration ............. dsatterwhite on PROD1PC76 with PROPOSALS Action Between 7 and 9 depending on airplane configuration. 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.

Regulatory Findings We have 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 that the 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 PO 00000 Frm 00017 Fmt 4702 Sfmt 4702 Number of U.S.-registered airplanes Cost per airplane Parts 25 Fleet cost $11,375 and $14,625 depending on airplane configuration. 3.

We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: E:\FR\FM\28MRP1.SGM 28MRP1 Federal Register / Vol. 71, No. 59 / Tuesday, March 28, 2006 / Proposed Rules TABLE 1.—AFFECTED AIRPLANES PART 39—AIRWORTHINESS DIRECTIVES All airbus model— 1.

RIN 2120-AA64

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: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt 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 proposed AD
would 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. This proposed 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 proposing 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: We must receive comments on this proposed AD by April 27, 2006.

Discussion

The Direction G[eacute]n[eacute]rale de l'Aviation Civile (DGAC),
which is the airworthiness authority for France, notified us that an
unsafe condition may exist on all Airbus Model A330-200, A330-300,
A340-200, and A340-300 series airplanes; and Model A340-541 and A340-
642 airplanes. The DGAC advises that the flow metering system (FMS) and
the flow metering compact unit (FMCU) (only on Model A340-200 and -300
series airplanes, and Model A340-541 and A340-642 airplanes) of the
fire extinguishing system may be blocked by anti-fretting material
contamination. The origin of this anti-fretting material contamination
inside the piping, filters, and pressure reducers may come from
manufacturing of the parts, as well as installation on airplanes during
production or maintenance. After the first activation of the fire
extinguishing system, the DGAC advises to assume that the FMS or FMCU
is contaminated, and that the fire

[[Page 15355]]

extinguishing system may not be fully operable for its next use.
Anti-fretting material contamination, if not corrected, 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) or 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.

Relevant Service Information

Airbus has issued the following service bulletins:

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

The service bulletins describe procedures for doing a one-time
general visual inspection for anti-fretting material contamination of
the Halon filters and plumbing parts of the FMS in the LDCC; doing
applicable corrective actions if necessary; and doing related
investigative and other specified actions. The applicable corrective
actions include cleaning any contaminated pressure reducer, pressure
switch, plumbing part, and Halon filter; and replacing any of those
parts with a new part if contamination cannot be removed. The related
investigative and other specified actions include inspecting the fire
extinguishing bottle to determine if it has been activated, cleaning
Halon filters and plumbing parts, and applying anti-fretting material.
Airbus also has issued Service Bulletin A340-26-5008, dated January
31, 2005 (for Model A340-642 airplanes). The service bulletin describes
procedures for doing a one-time general visual inspection for anti-
fretting material contamination of the plumbing parts of the FMCU in
the LDCC; doing applicable corrective actions if necessary; and doing
other specified actions. The applicable corrective actions include
replacing any plumbing part with a new part if contamination cannot be
removed. The other specified actions include replacing the FMCU with
new FMCUs, cleaning plumbing parts, and applying anti-fretting
material.
In addition, Airbus has issued the following service bulletins:

The revised AMMs describe procedures for restoring the fire
extinguishing system in the LDCC and in the BCRC, as applicable, after
any activation, and include a caution note in the work instructions
about how to apply anti-fretting material during the restoration,
which, when followed, prevents a malfunction of the system.
Accomplishing the actions specified in the service information is
intended to adequately address the unsafe condition.
The DGAC mandated the service information and issued French
airworthiness directives F-2005-019 R1 (for Model A330-200 and A330-300
series airplanes), and F-2005-020 R1 (for Model A340-200 and A340-300
series airplanes, and Model A340-541

[[Page 15356]]

and A340-642 airplanes); both dated May 11, 2005; to ensure the
continued airworthiness of these airplanes in France.

FAA's Determination and Requirements of the Proposed AD

These airplane models are manufactured in France and are type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement. Pursuant to this
bilateral airworthiness agreement, the DGAC has kept the FAA informed
of the situation described above. We have examined the DGAC's findings,
evaluated all pertinent information, and determined that we need to
issue an AD for airplanes of this type design that are certificated for
operation in the United States.
Therefore, we are proposing this AD, which would require
accomplishing the actions specified in the service information
described previously.

Clarification Between the Proposed AD and French Airworthiness
Directives

The French airworthiness directives specify the following
compliance times for inspecting the FMCU and FMS in the LDCC:

Compliance Times in French Airworthiness Directives
------------------------------------------------------------------------
For airplanes-- Compliance time
------------------------------------------------------------------------
On which the fire extinguishing system Within 6,600 flight hours after
is confirmed to have never been the effective date of the AD.
activated.
On which the fire extinguishing system Within 2,400 flight hours after
has been activated at least once or it the effective date of the AD.
is uncertain whether it has ever been
activated or not.
------------------------------------------------------------------------

Like the French airworthiness directive, the proposed AD would
require all affected airplanes to do the proposed actions within 2,400
flight hours after the effective date of the AD or within 6,600 flight
hours after the effective date of the AD if an operator can
conclusively determine that the fire extinguishing system has never
been activated. However, the French airworthiness directive does not
specify the means of making that determination. We have determined that
reviewing an airplane log book is not a reliable way to determine if a
fire extinguishing bottle has been activated, and that the only means
of making this determination is by reviewing the airplane maintenance
records. Therefore, this proposed AD would allow the proposed
inspections to be done within 6,600 flight hours after the effective
date of this AD, provided that reviewing the airplane maintenance
records can conclusively determine that the fire extinguishing system
has never been activated before the effective date of 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 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 that the 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. See the
ADDRESSES section for a location to examine the regulatory evaluation.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Safety.

The Proposed Amendment

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

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 Generale 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.''
