Comments will be available in the AD docket shortly after the Docket Management System receives them. Discussion We proposed to amend 14 CFR part 39 with a notice of proposed rulemaking (NPRM) for an airworthiness directive (AD) (the ‘‘original NPRM’’). The original NPRM applies to certain Airbus Model A330–200, A330–300, A340–200, and A340–300 series airplanes, and A340–541 and A340–642 airplanes. The original NPRM was published in the Federal Register on September 27, 2005 (70 FR 56389). The original NPRM proposed to require inspecting to determine if certain emergency escape slides/slide rafts (referred to as slide/ rafts) are installed in certain crew/ passenger doors; and, if so, performing a one-time inspection to determine if the electrical harnesses of the slide/rafts are properly routed, and rerouting the harnesses if necessary. Since the original NPRM was issued, we have determined that the applicability of the proposed AD was not properly written. As written, the applicability of the proposed AD would not have ensured that the unsafe condition would not recur if a slide/raft was ever replaced or reinstalled on any subject airplane. PO 00000 Frm 00028 Fmt 4702 Sfmt 4702 Comments We have considered the following comments on the original NPRM. Request To Update Service Information One commenter, the manufacturer, requests that we update the references to the applicable service information cited in the original NPRM. The commenter states that later revisions of two AOTs are available. We agree with this request. We have reviewed Airbus All Operators Telex (AOT) A330–25A3272, Revision 02, and AOT A340–25A4259, Revision 02, both dated June 1, 2005. Both AOTs were revised to add a reference to French airworthiness directive F–2005–077, dated May 11, 2005, and to remove the reference to door 3 type A from paragraph 4.1. We have determined that these revisions of the AOTs should be referenced in the AD. Therefore, we have revised paragraphs (c), (f)(1)(ii), and (f)(2)(ii) of the AD to reflect the revised AOTs, and revised paragraph (g) of the AD to give credit for using Revision 01 of those AOTs. Request To Clarify Applicability The same commenter requests that we clarify the applicability of the original NPRM. The commenter states that airplanes delivered after March 17, 2005, which is the date of issuance of the original issues of the AOTs, are not subject to the inspection required by paragraph (f) of the AD, provided no slide/raft has been replaced on any such airplane. The commenter states that Revision 02 of all three AOTs, all dated June 1, 2005, specifies this exception. We agree that the AOTs specify the exception noted by the commenter, and that an airplane supplied by the manufacturer after March 17, 2005, may not be subject to the unsafe condition. However, this will not ensure that the unsafe condition won’t recur should an operator receive such an airplane and replace or reinstall any subject slide/raft on that airplane. Therefore, we have not revised the applicability of the original NPRM to reflect the specified exception; rather, this supplemental NPRM would require doing the actions specified in the AOTs. As operators must continue to operate the airplane in the configuration required by the supplemental NPRM, unless an alternative method of compliance is approved, this requirement would ensure that the actions specified in the AOTs would be accomplished on all subject airplanes. We have determined that it is necessary to expand the applicability of the original NPRM to ensure that the unsafe condition does E:\FR\FM\27MRP1.SGM 27MRP1 Federal Register / Vol. 71, No. 58 / Monday, March 27, 2006 / Proposed Rules not recur on any subject airplane; therefore, we have revised the applicability of the supplemental NPRM to cover all subject airplanes, certificated in any category. Further, in this supplemental NPRM, we have included a new paragraph (h) that would require performing any replacement or reinstallation of any subject slide/raft on any subject airplane in accordance with this AD. Accordingly, we have re-identified existing paragraphs (h) and (i) of the original NPRM as paragraphs (i) and (j) of this supplemental NPRM. Request To Expand Applicability The same commenter requests that we add two additional models of airplanes, Model A330–302 and A330–303, to the applicability of the original NPRM. The commenter gave no reason for this request. We agree with this request. Model A330–302 and A330–303 airplanes may be subject to the same unsafe condition as all other airplanes identified in the original NPRM. We have revised the applicability of the supplemental NPRM accordingly. sroberts on PROD1PC70 with PROPOSALS Request To Expand Scope of NPRM One commenter states that the onetime inspection specified in the original NPRM will not be effective in preventing future occurrences of misrouting of the slide/raft wiring harness. The commenter states it added a procedure to its aircraft maintenance program for inspecting the slide/raft wiring harness routing during every slide/raft assembly installation, and recommends that the FAA take steps to ensure that all affected operators establish maintenance procedures similar to those of the commenter. We infer that the commenter holds that the NPRM is not sufficient in scope and should be expanded. We recognize the commenter’s concern. The manufacturer is working on revisions to the airplane maintenance manual (AMM) to clarify the differences between the routing of the wiring harnesses on the left- and right-hand sides of the airplane, which will accomplish a function similar to that of the commenter’s procedures. When the AMM has been revised, we may consider further rulemaking. However, we do not wish to delay correcting the unsafe condition until the manufacturer issues new service information that revises the AMM. Therefore, we have not changed the AD to reflect this issue. VerDate Aug<31>2005 18:28 Mar 24, 2006 Jkt 208001 15075 FAA’s Determination and Proposed Requirements of the Supplemental NPRM Certain changes discussed above expand the scope of the original NPRM; therefore, we have determined that it is necessary to reopen the comment period to provide additional opportunity for public comment on this supplemental NPRM. We prepared a regulatory evaluation of the estimated costs to comply with this supplemental NPRM and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation. Costs of Compliance This supplemental NPRM would affect about 27 airplanes of U.S. registry. The required actions would take about 3 work hours per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of the proposed AD for U.S. operators is $5,265 or $195 per airplane. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: 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.

SUMMARY: The FAA is revising an earlier NPRM for an airworthiness 
directive (AD) that would have applied to certain Airbus Model A330-
200, A330-300, A340-200, and A340-300 series airplanes, and A340-541 
and A340-642 airplanes. The original NPRM would have required 
inspecting to determine if certain emergency escape slides/slide

rafts (referred to as slide/rafts) are installed in certain crew/
passenger doors; and, if so, performing a one-time inspection to 
determine if the electrical harnesses of the slide/rafts are properly 
routed, and rerouting the harnesses if necessary. The original NPRM 
resulted from a report that a slide/raft failed to deploy properly 
during a deployment test. This action revises the original NPRM by 
expanding the applicability of the proposed AD. We are proposing this 
AD to detect and correct improper routing of the electrical harnesses 
of certain slide/rafts, which could prevent proper deployment of the 
slide/rafts and delay evacuation of passengers and flightcrew during an 
emergency.

Discussion

    We proposed to amend 14 CFR part 39 with a notice of proposed 
rulemaking (NPRM) for an airworthiness directive (AD) (the ``original 
NPRM''). The original NPRM applies to certain Airbus Model A330-200, 
A330-300, A340-200, and A340-300 series airplanes, and A340-541 and 
A340-642 airplanes. The original NPRM was published in the Federal 
Register on September 27, 2005 (70 FR 56389). The original NPRM 
proposed to require inspecting to determine if certain emergency escape 
slides/slide rafts (referred to as slide/rafts) are installed in 
certain crew/passenger doors; and, if so, performing a one-time 
inspection to determine if the electrical harnesses of the slide/rafts 
are properly routed, and rerouting the harnesses if necessary.
    Since the original NPRM was issued, we have determined that the 
applicability of the proposed AD was not properly written. As written, 
the applicability of the proposed AD would not have ensured that the 
unsafe condition would not recur if a slide/raft was ever replaced or 
reinstalled on any subject airplane.

Comments

    We have considered the following comments on the original NPRM.

Request To Update Service Information

    One commenter, the manufacturer, requests that we update the 
references to the applicable service information cited in the original 
NPRM. The commenter states that later revisions of two AOTs are 
available.
    We agree with this request. We have reviewed Airbus All Operators 
Telex (AOT) A330-25A3272, Revision 02, and AOT A340-25A4259, Revision 
02, both dated June 1, 2005. Both AOTs were revised to add a reference 
to French airworthiness directive F-2005-077, dated May 11, 2005, and 
to remove the reference to door 3 type A from paragraph 4.1. We have 
determined that these revisions of the AOTs should be referenced in the 
AD. Therefore, we have revised paragraphs (c), (f)(1)(ii), and 
(f)(2)(ii) of the AD to reflect the revised AOTs, and revised paragraph 
(g) of the AD to give credit for using Revision 01 of those AOTs.

Request To Clarify Applicability

    The same commenter requests that we clarify the applicability of 
the original NPRM. The commenter states that airplanes delivered after 
March 17, 2005, which is the date of issuance of the original issues of 
the AOTs, are not subject to the inspection required by paragraph (f) 
of the AD, provided no slide/raft has been replaced on any such 
airplane. The commenter states that Revision 02 of all three AOTs, all 
dated June 1, 2005, specifies this exception.
    We agree that the AOTs specify the exception noted by the 
commenter, and that an airplane supplied by the manufacturer after 
March 17, 2005, may not be subject to the unsafe condition. However, 
this will not ensure that the unsafe condition won't recur should an 
operator receive such an airplane and replace or reinstall any subject 
slide/raft on that airplane. Therefore, we have not revised the 
applicability of the original NPRM to reflect the specified exception; 
rather, this supplemental NPRM would require doing the actions 
specified in the AOTs. As operators must continue to operate the 
airplane in the configuration required by the supplemental NPRM, unless 
an alternative method of compliance is approved, this requirement would 
ensure that the actions specified in the AOTs would be accomplished on 
all subject airplanes. We have determined that it is necessary to 
expand the applicability of the original NPRM to ensure that the unsafe 
condition does

[[Page 15075]]

not recur on any subject airplane; therefore, we have revised the 
applicability of the supplemental NPRM to cover all subject airplanes, 
certificated in any category. Further, in this supplemental NPRM, we 
have included a new paragraph (h) that would require performing any 
replacement or reinstallation of any subject slide/raft on any subject 
airplane in accordance with this AD. Accordingly, we have re-identified 
existing paragraphs (h) and (i) of the original NPRM as paragraphs (i) 
and (j) of this supplemental NPRM.

Request To Expand Applicability

    The same commenter requests that we add two additional models of 
airplanes, Model A330-302 and A330-303, to the applicability of the 
original NPRM. The commenter gave no reason for this request.
    We agree with this request. Model A330-302 and A330-303 airplanes 
may be subject to the same unsafe condition as all other airplanes 
identified in the original NPRM. We have revised the applicability of 
the supplemental NPRM accordingly.

Request To Expand Scope of NPRM

    One commenter states that the one-time inspection specified in the 
original NPRM will not be effective in preventing future occurrences of 
misrouting of the slide/raft wiring harness. The commenter states it 
added a procedure to its aircraft maintenance program for inspecting 
the slide/raft wiring harness routing during every slide/raft assembly 
installation, and recommends that the FAA take steps to ensure that all 
affected operators establish maintenance procedures similar to those of 
the commenter. We infer that the commenter holds that the NPRM is not 
sufficient in scope and should be expanded.
    We recognize the commenter's concern. The manufacturer is working 
on revisions to the airplane maintenance manual (AMM) to clarify the 
differences between the routing of the wiring harnesses on the left- 
and right-hand sides of the airplane, which will accomplish a function 
similar to that of the commenter's procedures. When the AMM has been 
revised, we may consider further rulemaking. However, we do not wish to 
delay correcting the unsafe condition until the manufacturer issues new 
service information that revises the AMM. Therefore, we have not 
changed the AD to reflect this issue.

FAA's Determination and Proposed Requirements of the Supplemental NPRM

    Certain changes discussed above expand the scope of the original 
NPRM; therefore, we have determined that it is necessary to reopen the 
comment period to provide additional opportunity for public comment on 
this supplemental NPRM.

Costs of Compliance

    This supplemental NPRM would affect about 27 airplanes of U.S. 
registry. The required actions would take about 3 work hours per 
airplane, at an average labor rate of $65 per work hour. Based on these 
figures, the estimated cost of the proposed AD for U.S. operators is 
$5,265 or $195 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 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 supplemental NPRM and placed it in the AD docket. 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

25A5091, Revision 02, dated June 1, 2005.

    Note 1: For the purposes of this AD, a general visual inspection 
is: ``A visual examination of an interior or exterior area, 
installation, or assembly to detect obvious damage, failure, or 
irregularity. This level of inspection is made from within touching 
distance unless otherwise specified. A mirror may be necessary to 
ensure visual access to all surfaces in the inspection area. This 
level of inspection is made under normally available lighting 
conditions such as daylight, hangar lighting, flashlight, or 
droplight and may require removal or opening of access panels or 
doors. Stands, ladders, or platforms may be required to gain 
proximity to the area being checked.''
