Federal Register Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A330-200 and -300 series airplanes, A340-200 and - 300 series airplanes, and A340-541 and -642 airplanes. This AD requires repetitive borescope inspections of the left and right fuel tanks of the trimmable horizontal stabilizers (trim tanks) for detached or damaged float valves; related investigative/corrective actions if necessary; and the eventual replacement of all float valves in the left and right trim tanks with new, improved float valves, which terminates the need for the repetitive inspections. This AD also requires repetitive replacement of certain new, improved float valves. This AD results from reports of detached and damaged float valves in the trim tanks. We are issuing this AD to prevent, in the event of a lightning strike to the horizontal stabilizer, sparking of metal parts and debris from detached and damaged float valves, or a buildup of static electricity, which could result in ignition of fuel vapors and consequent fire or explosion.

Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Airbus Model A330-200 and -300 series airplanes, A340-200 and -
300 series airplanes, and A340-541 and -642 airplanes. This AD requires
repetitive borescope inspections of the left and right fuel tanks of
the trimmable horizontal stabilizers (trim tanks) for detached or
damaged float valves; related investigative/corrective actions if
necessary; and the eventual replacement of all float valves in the left
and right trim tanks with new, improved float valves, which terminates
the need for the repetitive inspections. This AD also requires
repetitive replacement of certain new, improved float valves. This AD
results from reports of detached and damaged float valves in the trim
tanks. We are issuing this AD to prevent, in the event of a lightning
strike to the horizontal stabilizer, sparking of metal parts and debris
from detached and damaged float valves, or a buildup of static
electricity, which could result in ignition of fuel vapors and
consequent fire or explosion.

DATES: This AD becomes effective March 13, 2006.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of March 13,
2006.

ADDRESSES: You may examine the AD docket on the Internet at <a href="http://dms.dot.gov">http://dms.dot.gov</a> or in person at the Docket Management Facility, U.S.

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 certain Airbus Model
A330 and A340 series airplanes. That NPRM was published in the Federal
Register on June 29, 2005 (70 FR 37296). That NPRM proposed to require
repetitive borescope inspections of the left and right fuel tanks of
the trimmable horizontal stabilizers (trim tanks) for detached or
damaged float valves; related investigative/corrective actions if
necessary; and the eventual replacement of all float valves in the left
and right trim tanks with new, improved float valves, which terminates
the need for the repetitive inspections. That NPRM also proposed to
require repetitive replacement of certain new, improved float valves.

[[Page 5972]]

Comments

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

Requests That Resulted in a Change to the NPRM

Request To Add Another Service Bulletin

One commenter requests that the NPRM reference an additional
service bulletin. The commenter explains that Airbus Service Bulletin
A330-28-3093, dated June 16, 2005, installs the same Airbus
modification number (53081) as Airbus Service Bulletin A330-28-3094,
dated April 7, 2005, which was referenced in the NPRM as an appropriate
source of service information. The commenter explains that the
effectivity in Airbus Service Bulletin A330-28-3093 includes all of the
commenter's airplanes, while Airbus Service Bulletin A330-28-3094 does
not.
We agree to add Airbus Service Bulletin A330-28-3093 as another
method of compliance to the requirements of the AD. We note that adding
this service bulletin is for the convenience of the operator in
accomplishing the actions required by this AD, and does not add or
remove any airplane listed in the applicability of this AD.

Request To Revise the Costs of Compliance

The same commenter requests that the NPRM be revised to add an
estimated cost for access to each of the valves during replacement of
the valves, which is a terminating action. The commenter notes that the
service information estimates a total of 76 hours of access related
labor time. The commenter estimates a more realistic value to be 116
hours. The commenter recognizes that access time is typically not
included in the labor estimates of ADs. However, the commenter advises
that there are no tasks in the A330 maintenance program that require
access to this area. Therefore, the access hours will be driven solely
and specifically by the NPRM.
We agree that, in this case, it is appropriate to consider the time
necessary for access. We also recognize that different operators may
have different access times based on different airplane configurations
or other considerations. The estimated cost information for access that
is provided by the manufacturer is the latest information that we have,
and we have revised the AD to reflect that estimate.

Requests That Did Not Result in a Change to the NPRM

Request To Address Defective Parts Manufacturer Approval (PMA) Parts

One commenter requests that the NPRM be modified to include
possible ``defective'' parts manufactured with a parts manufacturer
approval (PMA) that may be installed in lieu of the defective original
equipment manufacturer (OEM) part specified in the NPRM. The commenter
states that a ``known'' PMA part exists for the defective OEM part
specified in the NPRM, and may contain the same defects as the
specified OEM part. The commenter further points out that, if a PMA
part is defective and currently installed, the NPRM would not require
its removal.
We concur with the commenter's general request that, if we know
that an unsafe condition also exists in PMA parts, the AD should
address those parts, as well as the original parts. Contrary to the
commenter's assertion that the known PMA part is not covered by the
wording of the NPRM, the ``known'' PMA part identified by the commenter
does have the same part number as the part number specified in the
NPRM. Therefore, it is also subject to the requirements of this AD. We
are not aware of other PMA parts that may have a different part number.
The commenter's remarks are timely in that the Transport Airplane
Directorate currently is in the process of reviewing this issue as it
applies to transport category airplanes. We acknowledge that there may
be other ways of addressing this issue to ensure that unsafe PMA parts
are identified and addressed. Once we have thoroughly examined all
aspects of this issue, including input from industry, and have made a
final determination, we will consider whether our policy regarding
addressing PMA parts in ADs needs to be revised. We consider that to
delay this AD action would be inappropriate, since we have determined
that an unsafe condition exists and that replacement of certain parts
must be accomplished to ensure continued safety. Therefore, no change
has been made to the final rule in this regard.

Request to Reference PMA Parts

The same commenter also requests that the language in the NPRM be
changed to permit installation of PMA equivalent parts. The commenter
states that the mandated installation of a certain part number in the
NPRM ``is at variance with the higher authority of 14 CFR Section
21.303.''
We infer that the commenter would like the AD to permit
installation of any equivalent PMA parts so that it is not necessary
for an operator to request approval of an alternative method of
compliance (AMOC) in order to install an ``equivalent'' PMA part.
Whether an alternative part is ``equivalent'' in adequately resolving
the unsafe condition can only be determined on a case-by-case basis
based on a complete understanding of the unsafe condition. We are not
currently aware of any such parts. Our policy is that, in order for
operators to replace a part with one that is not specified in the AD,
they must request an AMOC. This is necessary so that we can make a
specific determination that an alternative part is or is not
susceptible to the same unsafe condition.
In response to the commenter's statement regarding a ``variance
with FAR 21.303,'' under which the FAA issues PMAs, this statement
appears to reflect a misunderstanding of the relationship between ADs
and the certification procedural regulations of part 21 of the FARs (14
CFR part 21). Those regulations, including section 21.303 of the FARs
(14 CFR part 21.303), are intended to ensure that aeronautical products
comply with the applicable airworthiness standards. But ADs are issued
when, notwithstanding those procedures, we become aware of unsafe
conditions in these products or parts. Therefore, an AD takes
precedence over design approvals when we identify an unsafe condition,
and mandating installation of a certain part number in an AD is not at
variance with section Sec. 21.303.
The AD provides a means of compliance for operators to ensure that
the identified unsafe condition is addressed appropriately. For an
unsafe condition attributable to a part, the AD normally identifies the
replacement parts necessary to obtain that compliance. As stated in
section 39.7 of the FARs (14 CFR 39.7), ``Anyone who operates a product
that does not meet the requirements of an applicable airworthiness
directive is in violation of this section.'' Unless an operator obtains
approval for an AMOC, replacing a part with one not specified by the AD
would make the operator subject to an enforcement action and result in
a civil penalty. No change to the AD is necessary in this regard.

Editorial Changes to the AD

Clarification of Alternative Method of Compliance (AMOC) Paragraph

We have revised this action to clarify the appropriate procedure
for notifying the principal inspector before using any

[[Page 5973]]

approved AMOC on any airplane to which the AMOC applies.

Explanation of Change to Applicability

We have revised the applicability of the existing AD to identify
model designations as published in the most recent type certificate
data sheet for the affected models.

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, at an average
labor rate per hour of $65, for U.S. operators of Model A330-200 and -
300 series airplanes to comply with this AD.

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

Currently, there are no affected Model A340-200 and -300 series
airplanes and A340-541 and -642 airplanes on the U.S. Register.
However, should an affected airplane be imported and placed on the U.S.
Register in the future, it would be subject to the actions of this AD.
The estimated costs would be the same as those listed above for the
Model A330-200 and -300 series airplanes.

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.

Note 1: For the purposes of this AD, a detailed inspection is:
``An intensive examination of a specific item, installation, or
assembly to detect damage, failure, or irregularity. Available
lighting is normally supplemented with a direct source of good
lighting at an intensity deemed appropriate. Inspection aids such as
mirror, magnifying lenses, etc., may be necessary. Surface cleaning
and elaborate procedures may be required.''
