ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for Airbus Model A319–100 series airplanes, Model A320–111 airplanes, Model A320–200 series airplanes, and Model A321–100 series airplanes equipped with any additional center tank (ACT). This proposed AD would require identifying the part number of the ACT and, for certain ACTs, replacing the outer ACT manhole cover and seal. This proposed AD is prompted by reports of an ACT fuel transfer failure due to air leakage around the seal of the outer manhole covers of the ACTs. We are proposing this AD to prevent this leakage, which could result in fuel or fuel vapor leaking into the cargo PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 compartment, and consequent increased risk of a fire in the cargo compartment.

Comments will be available in the AD docket shortly after the DMS receives them. 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 Airbus Model A319–100 series airplanes, Model A320–111 airplanes, Model A320–200 series airplanes, and Model A321–100 series airplanes equipped with certain additional center tanks (ACTs). The DGAC advises that it has received reports of an ACT fuel transfer failure due to extrusion of the outer ACT manhole cover seals, which allowed air leaks. Subsequent analysis revealed the need to change the installation process and modify the seal material to ensure a proper seal. Leakage around the ACT outer manhole cover seals could result in fuel or fuel vapor leaking into the cargo compartment, and consequent increased risk of a fire in the cargo compartment. Relevant Service Information Airbus has issued Service Bulletin A320–28–1105, Revision 01, dated March 18, 2003. The service bulletin describes procedures for airplanes having affected ACTs for replacing the outer ACT manhole cover with a reinforced manhole cover, and replacing the outer manhole cover seal with a new seal. The DGAC mandated Service Bulletin A320–28–1105 and issued French airworthiness directive F–2004– 038, dated March 17, 2004, to ensure the continued airworthiness of these airplanes in France. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. Service Bulletin A320–28–1105 states that its accomplishment ‘‘requires the prior or simultaneous accomplishment’’ of Service Bulletin A320–28–1087. However, this proposed AD would not require the actions specified in Service Bulletin A320–28–1087 because those actions are required by AD 2004–23–04, amendment 39–13859 (69 FR 65523, November 15, 2004). Airbus Service Bulletin A320–28– 1105 notes that Airbus Service Bulletins A320–28–1098 and A320–28–1086 ‘‘can be done’’ at the same time as Service Bulletin A320–28–1105, yet identifies those service bulletins as ‘‘concurrent requirements.’’ This proposed AD would not require either Service Bulletin A320–28–1086 (because those actions are required by AD 2004–23–04) or A320–28–1098 (because we have determined that those actions are not necessary to address the unsafe condition identified in this proposed AD). 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 products of this type design that are certificated for operation in the United States. Therefore, we are proposing this AD, which would require accomplishing the applicable actions specified in the service information described previously, except as discussed below. Difference Between Proposed AD and French Airworthiness Directive The French airworthiness directive limits its applicability to Airbus Model A319–100 series airplanes, Model A320–111 airplanes, Model A320–200 series airplanes, and Model A321–100 series airplanes equipped with ACTs having certain part numbers. However, this proposed AD would not limit the applicability to certain ACT part numbers, but would require operators to first identify the ACT part number and then modify only the affected ACTs. This action will ensure that the unsafe condition is addressed on the fleet. Costs of Compliance The following table provides the estimated costs for U.S. operators to comply with this proposed AD. ESTIMATED COSTS Work hours Action P/N identification ......................................................................

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. See the ADDRESSES section for a location to examine the regulatory evaluation. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): Comments Due Date (a) The Federal Aviation Administration must receive comments on this AD action by September 16, 2005.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for Airbus Model A319-100 series airplanes, Model A320-111 airplanes,
Model A320-200 series airplanes, and Model A321-100 series airplanes
equipped with any additional center tank (ACT). This proposed AD would
require identifying the part number of the ACT and, for certain ACTs,
replacing the outer ACT manhole cover and seal. This proposed AD is
prompted by reports of an ACT fuel transfer failure due to air leakage
around the seal of the outer manhole covers of the ACTs. We are
proposing this AD to prevent this leakage, which could result in fuel
or fuel vapor leaking into the cargo compartment, and consequent
increased risk of a fire in the cargo compartment.

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 Airbus Model A319-100 series airplanes,
Model A320-111 airplanes, Model A320-200 series airplanes, and Model
A321-100 series airplanes equipped with certain additional center tanks
(ACTs). The DGAC advises that it has received reports of an ACT fuel
transfer failure due to extrusion of the outer ACT manhole cover seals,
which allowed air leaks. Subsequent analysis revealed the need to
change the installation process and modify the seal material to ensure
a proper seal. Leakage around the ACT outer manhole cover seals could
result in fuel or fuel vapor leaking into the cargo compartment, and
consequent increased risk of a fire in the cargo compartment.

Relevant Service Information

Airbus has issued Service Bulletin A320-28-1105, Revision 01, dated
March 18, 2003. The service bulletin describes procedures for airplanes
having affected ACTs for replacing the outer ACT manhole cover with a
reinforced manhole cover, and replacing the outer manhole cover seal
with a new seal. The DGAC mandated Service Bulletin A320-28-1105 and
issued French airworthiness directive F-2004-038, dated March 17, 2004,
to ensure the continued airworthiness of these airplanes in France.
Accomplishing the actions specified in the service information is
intended to adequately address the unsafe condition.
Service Bulletin A320-28-1105 states that its accomplishment
``requires the prior or simultaneous accomplishment'' of Service
Bulletin A320-28-1087. However, this proposed AD would not require the
actions specified in Service Bulletin A320-28-1087 because those
actions are required by AD 2004-23-04, amendment 39-13859 (69 FR 65523,
November 15, 2004).
Airbus Service Bulletin A320-28-1105 notes that Airbus Service
Bulletins A320-28-1098 and A320-28-1086 ``can be done'' at the same
time as Service Bulletin A320-28-1105, yet identifies those service
bulletins as ``concurrent requirements.'' This proposed AD would not
require either Service Bulletin A320-28-1086 (because those actions are
required by AD 2004-23-04) or A320-28-1098 (because we have determined
that those actions are not necessary to address the unsafe condition
identified in this proposed AD).

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 products of this type design that are certificated for
operation in the United States.
Therefore, we are proposing this AD, which would require
accomplishing the applicable actions specified in the service
information described previously, except as discussed below.

Difference Between Proposed AD and French Airworthiness Directive

The French airworthiness directive limits its applicability to
Airbus Model A319-100 series airplanes, Model A320-111 airplanes, Model
A320-200 series airplanes, and Model A321-100 series airplanes equipped
with ACTs having certain part numbers. However, this proposed AD would
not limit the applicability to certain ACT part numbers, but would
require operators to first identify the ACT part number and then modify
only the affected ACTs. This action will ensure that the unsafe
condition is addressed on the fleet.

Costs of Compliance

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

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
airworthiness directive (AD):

Airbus: Docket No. FAA-2005-22120; Directorate Identifier 2004-NM-
92-AD.

Comments Due Date

(a) The Federal Aviation Administration must receive comments on
this AD action by September 16, 2005.

Affected ADs

(b) None.
Applicability: (c) This AD applies to Airbus Model A319-111, -
112, -113, -114, -115, -131, -132, and -133 airplanes; Model A320-
111, -211, -212, -214, -231, -232, and -233 airplanes; and Model
A321-111, -112, and -131 airplanes; certificated in any category;
which are equipped with any additional center tank (ACT).

Unsafe Condition

(d) This AD was prompted by reports of an ACT fuel transfer
failure due to air leakage around the seal of the outer manhole
covers of the ACTs. We are requiring this AD to prevent this
leakage, which could result in fuel or fuel vapor leaking into the
cargo compartment, and consequent increased risk of a fire in the
cargo compartment.
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.

Part Number Identification

(f) Within 30 days (for Model A319-111, -112, -113, -114, -115,
-131, -132, and -133 airplanes) or 12 months (for Model A320-111, -
211, -212, -214, -231, -232, and -233 airplanes; and Model A321-111,
-112, and -131 airplanes) after the effective date of this AD:
Determine whether the part number (P/N) of each ACT installed on the
airplane is included in Table 1 of this AD. If no ACT installed on
the airplane has a P/N included in Table 1 of this AD, no further
work is required by this paragraph.
