ACTION: Final rule. sroberts on PROD1PC70 with RULES AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Airbus transport category airplanes. This AD requires replacing the existing vent float valve with a new, improved vent float valve. This AD results from reports of failure of the vent float valve in the left-hand outboard section of the trimmable horizontal stabilizer. 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 July 17, 2006. VerDate Aug<31>2005 18:28 Jun 09, 2006 Jkt 208001 The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of July 17, 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 transport category airplanes. That NPRM was published in the Federal Register on March 8, 2006 (71 FR 11555). That NPRM proposed to require replacing the existing vent float valve with a new, improved vent float valve. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments received. Request To Add Revised Service Information The manufacturer, Airbus, advises that both of the service bulletins (Airbus Service Bulletins A300–28–6081 and A310–28–2155, both dated February 16, 2005) specified in the NPRM have been revised. Airbus notes that Airbus Service Bulletins A300–28–6081, Revision 01, dated October 11, 2005; and A310–28–2155, Revision 01, dated October 17, 2005, contain minor changes and that no additional work is required. PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 We agree with Airbus and have revised paragraph (f) of the AD to reflect the revised service bulletins. In addition, we have added a new paragraph (g) of this AD specifying that accomplishment of the actions specified in paragraph (f) of the AD in accordance with the original issuance of the service bulletins, as applicable, is considered to be an acceptable method of compliance. Subsequent paragraphs of the AD have been re-identified accordingly. Request To Add a Phrase One commenter, Modification and Replacement Parts Association (MARPA), states that the requirement to install a certain part number to the exclusion of any other part nullifies part 21 of the Federal Aviation Regulations (14 CFR part 21) by preventing the development and/or use of alternative parts. MARPA submits that this can be averted by adding the common phrase ‘‘or FAA-approved equivalent part number’’ as a suffix to the part number mandated to be installed. Additionally, MARPA referenced an existing AD that contains the phrase MARPA suggests. In response to MARPA’s request to add the phrase ‘‘or FAA-approved equivalent part number,’’ we do not agree. Whether an alternative part is ‘‘equivalent’’ in adequately resolving the unsafe condition can be determined only on a case-by-case basis based on a complete understanding of the unsafe condition. Our policy is that, in order for operators to replace a part with one that is not specified in the AD, they must request and receive approval of an Alternative Method of Compliance (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 that the requirement to install a certain part number part to the exclusion of any other part nullifies part 21 of the FARs (14 CFR part 21) under which the FAA issues parts manufacturer approvals (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 21.303), are intended to ensure that aeronautical products and parts are safe. 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 other ‘‘approvals’’ when we identify an E:\FR\FM\12JNR1.SGM 12JNR1 Federal Register / Vol. 71, No. 112 / Monday, June 12, 2006 / Rules and Regulations 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. No change to the AD is necessary in this regard. 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. sroberts on PROD1PC70 with RULES Costs of Compliance This AD will affect about 179 airplanes of U.S. registry. The actions will take about 4 work hours per airplane, at an average labor rate of $65 per work hour. Required parts will be provided by the manufacturer at no cost to the operator. Based on these figures, the estimated cost of this AD for U.S. operators is $46,540, or $260 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 VerDate Aug<31>2005 18:28 Jun 09, 2006 Jkt 208001 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.

The existing AD applies to certain BAE Systems (Operations) Limited Model BAe 146 and Avro 146-RJ airplanes. That NPRM was published in the Federal Register on December 13, 2005 (70 FR 73665). That NPRM proposed to continue to require inspections of certain inner webs and flanges for signs of corrosion (including cracks, PO 00000 Frm 00008 Fmt 4700 Sfmt 4700 blistering, or flaking paint), and corrective action if necessary. That NPRM also proposed to add repetitive inspections, expand the area to be inspected, expand the applicability, and provide an optional action that would extend the proposed repetitive inspection interval. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comment that has been received on the NPRM. Request To Require Revised Service Information Air Wisconsin requests that we delay issuing the final rule until the manufacturer revises Inspection Service Bulletin (ISB) ISB.53–182, dated March 16, 2005 (cited in the NPRM). The commenter reports that BAE plans to revise the ISB to extend the inspection area after recent inspection data revealed evidence of corrosion cracking on some frame outer flanges. The commenter states that delaying issuance of the final rule would allow time to determine whether the revised ISB better addresses the identified unsafe condition. The commenter adds that it just makes more sense in regards to cost effectiveness and airworthiness safety for operators to perform the most thorough and up-to-date inspection on their airplanes. We acknowledge the commenter’s concern, but we do not agree to delay the issuance of the final rule. Release of a revised service bulletin is not imminent. To delay this action would be inappropriate because we have determined that an unsafe condition exists. However, we may consider further rulemaking in the future to expand the inspection area if warranted. In light of the identified unsafe condition, however, we consider it appropriate to proceed with this final rule as proposed. Conclusion We have carefully reviewed the available data, including the comment that has been submitted, and determined that air safety and the public interest require adopting the AD as proposed.

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 
transport category airplanes. That NPRM was published in the Federal 
Register on March 8, 2006 (71 FR 11555). That NPRM proposed to require 
replacing the existing vent float valve with a new, improved vent float 
valve.

Comments

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

Request To Add Revised Service Information

    The manufacturer, Airbus, advises that both of the service 
bulletins (Airbus Service Bulletins A300-28-6081 and A310-28-2155, both 
dated February 16, 2005) specified in the NPRM have been revised. 
Airbus notes that Airbus Service Bulletins A300-28-6081, Revision 01, 
dated October 11, 2005; and A310-28-2155, Revision 01, dated October 
17, 2005, contain minor changes and that no additional work is 
required.
    We agree with Airbus and have revised paragraph (f) of the AD to 
reflect the revised service bulletins. In addition, we have added a new 
paragraph (g) of this AD specifying that accomplishment of the actions 
specified in paragraph (f) of the AD in accordance with the original 
issuance of the service bulletins, as applicable, is considered to be 
an acceptable method of compliance. Subsequent paragraphs of the AD 
have been re-identified accordingly.

Request To Add a Phrase

    One commenter, Modification and Replacement Parts Association 
(MARPA), states that the requirement to install a certain part number 
to the exclusion of any other part nullifies part 21 of the Federal 
Aviation Regulations (14 CFR part 21) by preventing the development 
and/or use of alternative parts. MARPA submits that this can be averted 
by adding the common phrase ``or FAA-approved equivalent part number'' 
as a suffix to the part number mandated to be installed. Additionally, 
MARPA referenced an existing AD that contains the phrase MARPA 
suggests.
    In response to MARPA's request to add the phrase ``or FAA-approved 
equivalent part number,'' we do not agree. Whether an alternative part 
is ``equivalent'' in adequately resolving the unsafe condition can be 
determined only on a case-by-case basis based on a complete 
understanding of the unsafe condition. Our policy is that, in order for 
operators to replace a part with one that is not specified in the AD, 
they must request and receive approval of an Alternative Method of 
Compliance (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 that the requirement to 
install a certain part number part to the exclusion of any other part 
nullifies part 21 of the FARs (14 CFR part 21) under which the FAA 
issues parts manufacturer approvals (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 21.303), are 
intended to ensure that aeronautical products and parts are safe. 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 other ``approvals'' when we identify an

[[Page 33601]]

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. No change to 
the AD is necessary in this regard.

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

    This AD will affect about 179 airplanes of U.S. registry. The 
actions will take about 4 work hours per airplane, at an average labor 
rate of $65 per work hour. Required parts will be provided by the 
manufacturer at no cost to the operator. Based on these figures, the 
estimated cost of this AD for U.S. operators is $46,540, or $260 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:

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The Federal Aviation Administration (FAA) amends Sec.  39.13 by 
adding the following new airworthiness directive (AD):

2006-12-01 Airbus: Amendment 39-14625. Docket No. FAA-2006-24103; 
Directorate Identifier 2005-NM-241-AD.

Effective Date

    (a) This AD becomes effective July 17, 2006.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Airbus Model A300 B4-605R and B4-622R 
airplanes, A300 C4-605R Variant F airplanes, A300 F4-605R and F4-
622R airplanes; and Model A310-304, -322, -324, and -325 airplanes; 
certificated in any category, except those airplanes on which Airbus 
Modification 12897 has been accomplished in production.

Unsafe Condition

    (d) This AD results from reports of a broken vent float valve in 
the left-hand outboard section of the trimmable horizontal 
stabilizer. 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.

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.

Action Heading

    (f) Within 36 months after the effective date of this AD: 
Replace Intertechnique vent float valve, part number (P/N) L87-13-
001, in the trim tank with P/N L87-13-003; in accordance with Airbus 
Service Bulletin A300-28-6081, Revision 01, dated October 11, 2005 
(for Model A300 B4-605R and B4-622R airplanes, A300 C4-605R Variant 
F airplanes, and A300 F4-605R and F4-622R airplanes); or A310-28-
2155, Revision 01, dated October 17, 2005 (for Model A310-304, -322, 
-324, and -325 airplanes).

Acceptable for Compliance

    (g) Accomplishment of the actions required by paragraph (f) of 
this AD that are done before the effective date of this AD in 
accordance with Airbus Service Bulletin A300-28-6081 (for Model A300 
B4-605R and B4-622R airplanes, A300 C4-605R Variant F airplanes, and 
A300 F4-605R and F4-622R airplanes) or A310-28-2155 (for Model A310-
304, -322, -324, and -325 airplanes), both dated February 16, 2005, 
is acceptable for compliance with the requirements of paragraph (f) 
of this AD.

Alternative Methods of Compliance (AMOCs)

    (h)(1) The Manager, International Branch, ANM-116, has the 
authority to approve AMOCs for this AD, if requested in accordance 
with the procedures found in 14 CFR 39.19.
    (2) Before using any AMOC approved in accordance with Sec.  
39.19 on any airplane to which the AMOC applies, notify the 
appropriate principal inspector in the FAA Flight Standards 
Certificate Holding District Office.

Parts Installation

    (i) As of the effective date of this AD, no person may install a 
vent float valve, P/N L87-13-001, on any airplane.
