Airworthiness Directives; Airbus Model A330–200 and –300 Series Airplanes, A340–200 and –300 Series Airplanes, and A340–541 and –642 Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: 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 PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 Examining the Docket 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. E:\FR\FM\06FER1.SGM 06FER1 5972 Federal Register / Vol. 71, No. 24 / Monday, February 6, 2006 / Rules and Regulations Requests That Did Not Result in a Change to the NPRM 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 wwhite on PROD1PC65 with RULES 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. VerDate Aug<31>2005 16:29 Feb 03, 2006 Jkt 208001 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 PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 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 § 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 E:\FR\FM\06FER1.SGM 06FER1 5973 Federal Register / Vol. 71, No. 24 / Monday, February 6, 2006 / Rules and Regulations approved AMOC on any airplane to which the AMOC applies. economic burden on any operator nor increase the scope of the AD. Conclusion 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. 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 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. ESTIMATED COSTS Number of U.S. registered airplanes Cost per airplane Action Work hours Parts Repetitive borescope inspection, per inspection cycle. Installation of float valves (including access). Bonding test (new, improved float valves, left trim tank only). 2 hours for inspection ....................... None ........ $130 25 4 hours (2 per valve, 2 valves per airplane) plus 76 hours for access. 1 ........................................................ No charge 5,200 25 65 25 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. None ........ Fleet cost $3,250, per inspection cycle. $130,000, per installation. $1,625. Regulatory Findings Adoption of the Amendment 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.

Airworthiness Directives; Airbus Model A330-200 and -300 Series 
Airplanes, A340-200 and -300 Series Airplanes, and A340-541 and -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 
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 http://
dms.dot.gov or in person at the Docket Management Facility, U.S. 
Department of Transportation, 400 Seventh Street, SW., Nassif Building, 
Room PL-401, Washington, DC.
    Contact Airbus, 1 Rond Point Maurice Bellonte, 31707 Blagnac Cedex, 
France, for service information identified in this AD.

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 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.

float valves in the left and right fuel tanks of the trimmable 
horizontal stabilizers (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.

    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.''

Installation of New, Improved Float Valves

    (h) Within 50 months after the effective date of this AD: 
Replace any Argo-Tech float valve, P/N 61600, with a new, improved 
float valve, P/N 62015-1; replace any Intertechnique float valve, P/
N L87-13-001, with a new, improved float valve, P/N L87-13-002 or P/
N L87-13-003; and do any applicable corrective action; by 
accomplishing the actions specified in the Accomplishments 
Instructions of the applicable service bulletin in Table 3 of this 
AD. Do any applicable corrective action before further flight. For 
Airbus Model A330-201, -202, -203, -223, --243, -301, -321, -322, -
323, -341, -342, and -343 airplanes: If P/N L87-13-002 is installed, 
replace the float valve thereafter at intervals not to exceed 24,500 
flight cycles. Installation of P/N L87-13-003 on Airbus Model A330-
201, -202, -203, -223, --243, -301, -321, -322, -323, -341, -342, 
and -343 airplanes terminates the repetitive float valve replacement 
required by this paragraph. Installation of either P/N L87-13-002 or 
P/N L87-13-003 terminates the borescope inspections required by 
paragraphs (f) and (g) of this AD. Where the service bulletin 
specifies to contact the manufacturer, instead contact the Manager, 
International Branch, ANM-116, or the DGAC (or its delegated agent).
