ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A300 B4–600, B4–600R, and F4–600R series airplanes, and Model C4–605R Variant F airplanes (collectively called A300–600 series airplanes); and Model A310–300 series airplanes. This AD requires inspecting the pilot’s and co-pilot’s seats to determine if a certain actuator having a certain part number is installed, and corrective action if necessary. This AD results from a production defect found in certain actuators during overhaul of the pilot’s and co-pilot’s seats. We are issuing this AD to prevent uncommanded movement of the pilot’s or co-pilot’s seat, which could result in interference with the operation of the airplane and consequent temporary loss of airplane control. DATES: This AD becomes effective March 24, 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 certain Airbus Model A300 B4– 600, B4-600R, and F4–600R series airplanes, and Model C4–605R Variant F airplanes (collectively called A300–600 series airplanes); and Model A310–300 series airplanes. That NPRM was published in the Federal Register on September 19, 2005 (70 FR 54852). That NPRM proposed to require inspecting the pilot’s and co-pilot’s seats to determine if a certain actuator having a certain part number is installed, and corrective action if necessary. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. wwhite on PROD1PC61 with RULES Request To Include Revised Service Information One commenter, the airplane manufacturer, asks that we change the NPRM to refer to Airbus Service Bulletin A300–25–6194, Revision 01, dated April 8, 2005 (for A300–600 series VerDate Aug<31>2005 18:49 Feb 16, 2006 Jkt 208001 airplanes), as an ‘‘acceptable means of compliance’’ for accomplishing the actions. The NPRM refers to the original issue of the service bulletin as the acceptable source of service information for accomplishing the proposed actions. We agree with the commenter’s request. The procedures in Revision 01 of the referenced service bulletin are essentially the same as those in the original issue of the service bulletin. Revision 01 merely adds one manufacturer serial number to those identified in the service bulletin effectivity. Accordingly, we have revised paragraph (f) of this AD to refer to Revision 01 as the appropriate source of service information for accomplishing the required actions. We have also added a new paragraph (g) (and reidentified subsequent paragraphs accordingly) to state that inspections and corrective actions accomplished before the effective date of this AD per the original issue of the service bulletin are acceptable for compliance with this AD. Request To Reference Parts Manufacturer Approval (PMA) Parts One commenter 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 ‘‘is in conflict with existing law (FAR 21.303),’’ which permits the installation of other PMA parts. We infer that the commenter would like the AD to permit installation of any equivalent PMA part 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 Federal Aviation Regulations (14 CFR part 21). Those regulations, including section 21.303 of PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 8437 the Federal Aviation Regulations (14 CFR 21.203), are intended to ensure that aeronautical products comply with the applicable airworthiness standards. 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 Federal Aviation Regulations (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. We have made no change to the AD in this regard. Request To Address Defective PMA Parts The same commenter also requests that the NPRM be revised to cover possible defective PMA alternative parts, rather than just a single part number, so that those defective PMA parts also are subject to the NPRM. The commenter states that, often, the service document specifies a defective part with the requirement that the defective part be replaced by a ‘‘new and improved’’ part. This fails to address the possibility that a PMA part may be installed instead of the original part. Since the PMA part may often share the identical design data with the original part, while having a completely different part number, it is possible that the AD will not address certain defective PMA parts installed on the airplane. This would allow the unsafe condition to continue. We agree 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. As the commenter states, in this case, the identified PMA part has a different part number than the original, and is therefore not subject to the requirements of this AD. We are not aware of other PMA parts that have a different part number. The commenter’s remarks are timely in that the Transport Airplane E:\FR\FM\17FER1.SGM 17FER1 8438 Federal Register / Vol. 71, No. 33 / Friday, February 17, 2006 / Rules and Regulations 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, we have made no change to the AD in this regard. Clarification of AMOC Paragraph We have revised paragraph (j) of this AD to clarify the appropriate procedure for notifying the principal inspector before using any approved AMOC on any airplane to which the AMOC applies. 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. These changes will neither increase the economic burden on any operator nor increase the scope of the AD. wwhite on PROD1PC61 with RULES Costs of Compliance This AD affects about 169 airplanes of U.S. registry. The inspection takes about 1 work hour per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of the AD for U.S. operators is $10,985, or $65 per airplane. 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 VerDate Aug<31>2005 18:49 Feb 16, 2006 Jkt 208001 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.

ACTION: Final rule. AGENCY: SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A319, A320, and A321 series airplanes. That AD currently requires repetitive inspections to detect wear of the inboard flap trunnions, and to detect wear or de-bonding of the protective half-shells; corrective actions, if necessary; and terminating action. This new AD removes the repetitive inspections to detect wear of the inboard flap trunnions and to detect wear or de-bonding of the protective half-shells; and corrective actions if necessary. This new AD adds repetitive detailed inspections of the inboard flap trunnions for any wear marks and of the sliding panels for any cracking at the long edges, and corrective actions if necessary. This new AD also adds airplanes to the applicability. This AD results from reports of wear damage to the inboard flap trunnions after incorporation of the terminating modification. We are issuing this AD to detect and correct wear of the inboard flap trunnions, which could lead to loss of flap surface control and consequently result in the flap detaching from the airplane. A detached flap could result in damage to the tail of the airplane. DATES: This AD becomes effective March 24, 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 certain Airbus Model 
A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R 
Variant F airplanes (collectively called A300-600 series airplanes); 
and Model A310-300 series airplanes. That NPRM was published in the 
Federal Register on September 19, 2005 (70 FR 54852). That NPRM 
proposed to require inspecting the pilot's and co-pilot's seats to 
determine if a certain actuator having a certain part number is 
installed, and corrective action 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 Include Revised Service Information

    One commenter, the airplane manufacturer, asks that we change the 
NPRM to refer to Airbus Service Bulletin A300-25-6194, Revision 01, 
dated April 8, 2005 (for A300-600 series airplanes), as an ``acceptable 
means of compliance'' for accomplishing the actions. The NPRM refers to 
the original issue of the service bulletin as the acceptable source of 
service information for accomplishing the proposed actions.
    We agree with the commenter's request. The procedures in Revision 
01 of the referenced service bulletin are essentially the same as those 
in the original issue of the service bulletin. Revision 01 merely adds 
one manufacturer serial number to those identified in the service 
bulletin effectivity. Accordingly, we have revised paragraph (f) of 
this AD to refer to Revision 01 as the appropriate source of service 
information for accomplishing the required actions. We have also added 
a new paragraph (g) (and re-identified subsequent paragraphs 
accordingly) to state that inspections and corrective actions 
accomplished before the effective date of this AD per the original 
issue of the service bulletin are acceptable for compliance with this 
AD.

Request To Reference Parts Manufacturer Approval (PMA) Parts

    One commenter 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 ``is in conflict 
with existing law (FAR 21.303),'' which permits the installation of 
other PMA parts.
    We infer that the commenter would like the AD to permit 
installation of any equivalent PMA part 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 Federal 
Aviation Regulations (14 CFR part 21). Those regulations, including 
section 21.303 of the Federal Aviation Regulations (14 CFR 21.203), are 
intended to ensure that aeronautical products comply with the 
applicable airworthiness standards. 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 Federal Aviation Regulations (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. We have made no 
change to the AD in this regard.

Request To Address Defective PMA Parts

    The same commenter also requests that the NPRM be revised to cover 
possible defective PMA alternative parts, rather than just a single 
part number, so that those defective PMA parts also are subject to the 
NPRM. The commenter states that, often, the service document specifies 
a defective part with the requirement that the defective part be 
replaced by a ``new and improved'' part. This fails to address the 
possibility that a PMA part may be installed instead of the original 
part. Since the PMA part may often share the identical design data with 
the original part, while having a completely different part number, it 
is possible that the AD will not address certain defective PMA parts 
installed on the airplane. This would allow the unsafe condition to 
continue.
    We agree 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. As the commenter states, in 
this case, the identified PMA part has a different part number than the 
original, and is therefore not subject to the requirements of this AD. 
We are not aware of other PMA parts that have a different part number. 
The commenter's remarks are timely in that the Transport Airplane

[[Page 8438]]

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, we have 
made no change to the AD in this regard.

Clarification of AMOC Paragraph

    We have revised paragraph (j) of this AD to clarify the appropriate 
procedure for notifying the principal inspector before using any 
approved AMOC on any airplane to which the AMOC applies.

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. 
These changes will neither increase the economic burden on any operator 
nor increase the scope of the AD.

Costs of Compliance

    This AD affects about 169 airplanes of U.S. registry. The 
inspection takes about 1 work hour per airplane, at an average labor 
rate of $65 per work hour. Based on these figures, the estimated cost 
of the AD for U.S. operators is $10,985, or $65 per airplane.

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.
