ACTION: Final rule. AGENCY: SUMMARY: The FAA is superseding an existing airworthiness directive (AD) that applies to certain Boeing Model 767–200, –300, and –300F series airplanes. That AD currently requires an inspection of visually accessible areas for indications of overheating of the heater tape attached to the potable water fill and drain lines in the forward and aft cargo compartments, exposed foam insulation or missing or damaged protective tape around the potable water fill and drain lines, and debris or contaminants on or near the potable water fill and drain lines. That AD also requires corrective action, as necessary. This new AD requires repetitive inspections of the forward and aft cargo compartments, as applicable, for discrepancies of the potable water supply and gray water drain lines; and applicable corrective actions if necessary. This AD also requires replacing the heater tapes on the potable water supply and gray water drain lines of the forward and aft cargo compartments, as applicable, with new ribbon heaters, or deactivating and removing any defective heater tape and wrapping the drain line with foam insulation; either action ends the repetitive inspections. This AD results from a report of a fire in the aft cargo compartment. We are issuing this AD to prevent overheating of the heater tape on potable water fill and drain lines, which may ignite accumulated debris or contaminants on or near the potable water fill and drain lines, resulting in a fire in the airplane. DATES: This AD becomes effective March 5, 2007. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of March 5, 2007.

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 supersedes AD 2002–11–11, amendment 39–12772 (67 FR 39265, June 7, 2002). The existing AD applies to certain Boeing Model 767–200, –300, and –300F series airplanes. That NPRM was published in the Federal Register on June 30, 2006 (71 FR 37507). That NPRM proposed to require repetitive inspections of the forward and aft cargo compartments, as applicable, for discrepancies of the potable water supply and gray water drain lines; and applicable corrective actions if necessary. That NPRM also proposed to require replacing the heater tapes on the potable water supply and gray water drain lines of the forward and aft cargo compartments, as applicable, with new ribbon heaters, which would end the repetitive inspections. rmajette on PROD1PC67 with RULES Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comments that have been received on the NPRM. Request To Permit Alternative Method of Compliance Boeing requests that we permit an alternative method of compliance for the terminating action described in the NPRM. Boeing states that Boeing VerDate Aug<31>2005 14:38 Jan 26, 2007 Jkt 211001 Service Bulletin 767–30A0038, Revision 2, dated February 23, 2006, describes procedures for deactivating and removing the heater tapes of certain gray water drain lines and wrapping the drain lines with foam insulation. Boeing therefore requests that we revise the summary and paragraph (h), Terminating Action, of the NPRM to state that the alternative action described here is acceptable as a terminating action for the requirements of the AD. We agree for the reasons stated. Accordingly, we have revised the summary of the AD, revised paragraph (h) of the AD to include new paragraphs (h)(1) and (h)(2), and removed paragraph identifiers (1) and (2) from Table 2 of the AD. We have also revised the Costs of Compliance section of the AD to present the estimated costs for deactivation and removal of the heating tapes and installation of foam insulation. These actions neither increase the economic burden on any operator nor increase the scope of the AD. Request To Clarify Costs of Compliance Boeing requests that we clarify the Costs of Compliance section of the NPRM. Boeing states that the Estimated Costs table is not clear and asserts that the time estimated for performing the inspections should be ‘‘2 or 3’’ work hours. Boeing further asserts that Boeing Service Bulletin 767–30A0038 specifies ‘‘between 4.75 and 11 work hours’’ to perform the heater tape replacements. Although Boeing made no specific request, we infer that Boeing wishes us to revise the Costs of Compliance section to more closely reflect the estimated costs specified in the service bulletin. We partially agree. We concur that the time estimated for performing the inspections should be 2 or 3 work hours, as shown in the Estimated Costs table. However, the statement that ‘‘between 4.75 and 11 work hours’’ are required to replace the heater tapes does not accurately reflect the service information we have reviewed. The service bulletin provides an estimate of between 4.75 and 11 work hours to gain access, perform inspections, replacements and tests, and close access. Typically, the costs specified in an AD are only the direct costs of the specific actions required by the AD. Therefore, the figures shown in the Estimated Costs table of this AD do not include the time to gain and close access or perform testing. Further, the remaining work hours specified to do the direct actions are divided into two parts: one part to perform the PO 00000 Frm 00007 Fmt 4700 Sfmt 4700 3931 inspections and one part to replace the ribbon heater or to remove the heater and install foam insulation. We have made no changes to the AD in regard to these comments. Comment Regarding Applicability A private citizen states that the NPRM does not apply to Model 767 freighter airplanes. We agree. The AD does not apply to Model 767–300F or –400ER series airplanes (freighters), but only to Model 767–200 and –300 series airplanes, as stated in the NPRM. No change is needed to the AD in this regard. Request for Posting of Service Information The Modification and Replacement Parts Association (MARPA), requests that we revise our procedures for incorporation by reference (IBR) of service information in ADs. MARPA states that, as an AD is a public regulatory instrument, it can not rely upon private writings. MARPA asserts that such IBR documents lose any proprietary, protected status they originally had and become public documents and, therefore, that they must be published in the Docket Management System (DMS), keyed to the action that incorporates them. MARPA addresses the stated purpose of the Federal Register IBR method, brevity, which is intended to relieve the Federal Register of needlessly publishing documents already supplied to affected individuals: owners and operators of affected aircraft. MARPA asserts that ‘‘affected individuals’’ are no longer merely owners and operators, but, since most aircraft maintenance is now performed by specialty shops, that a new class of affected individuals has emerged. This new class includes maintenance and repair organizations, component servicing and repair shops, parts purveyors and distributors, and organizations manufacturing or servicing alternatively certified parts under 14 CFR 21.303 (PMA). Further, MARPA contends that the concept of brevity is now nearly archaic as most documents are kept in electronic files. MARPA therefore requests that IBR documents be incorporated by reference into the regulatory instrument and posted in the DMS docket for the applicable AD. We acknowledge MARPA’s comments. The Office of the Federal Register (OFR) requires that documents that are necessary to accomplish the requirements of the AD be incorporated by reference during the final rule phase of rulemaking. This final rule incorporates by reference the document E:\FR\FM\29JAR1.SGM 29JAR1 3932 Federal Register / Vol. 72, No. 18 / Monday, January 29, 2007 / Rules and Regulations necessary for the accomplishment of the requirements mandated by this AD. Further, we point out that while documents that are incorporated by reference do become public information, they do not lose their copyright protection. For that reason, we advise the public to contact the manufacturer to obtain copies of the referenced service information. In regard to MARPA’s request to post service documents on the Department of Transportation’s DMS, we are currently in the process of reviewing issues surrounding the posting of service documents on the DMS as part of an AD docket. Once we have thoroughly examined all aspects of this issue and have made a final determination, we will consider whether our current practice needs to be revised. No change to the final rule is necessary in response to this comment. Request for Standardized Directorate Policies MARPA requests standardized directorate policies, asserting that another directorate has already given a blanket parts manufacturer approval (PMA) by stating in published rules that ‘‘FAA-approved equivalent parts’’ may be used. MARPA contends that, by not using similar language, we are not in compliance with Executive Order 12866 or proposed FAA order 8040.2. MARPA asserts that for us to not include similar blanket language at the earliest possible time could work to our disadvantage legally. We recognize the need for standardization on this issue and currently are in the process of reviewing issues that address PMAs at the national level. However, the Transport Airplane Directorate considers that to delay this particular 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. Conclusion We have carefully reviewed the available data, including the comments that have been 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 There are about 455 airplanes of the affected design in the worldwide fleet. The following table provides the estimated costs for U.S. operators to comply with this AD.

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. 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.

ACTION: Final rule. rmajette on PROD1PC67 with RULES AGENCY: Discussion SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 747 airplanes. This AD requires repetitive inspections for cracking of the web of the station (STA) 2360 aft pressure bulkhead around the fastener heads in the critical fastener rows in the web lap joints, from the Ychord to the inner ring; and repair if necessary. This AD also requires a modification, which terminates the repetitive inspections. This AD results from analysis by the manufacturer that The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to all Boeing Model 747 airplanes. That NPRM was published in the Federal Register on April 11, 2006 (71 FR 18242). That NPRM proposed to require repetitive inspections for cracking of the web of the station (STA) 2360 aft pressure bulkhead around the fastener heads in the critical fastener rows in the web lap joints, from the Ychord to the inner ring; and repair if necessary. That NPRM also proposed to require a modification, which would terminate the repetitive inspections.

We have considered the comments received. Support for the NPRM Boeing supports the NPRM as written. Request To Postpone the AD Japan Airlines (JAL) states that Boeing Alert Service Bulletin 747–53A2561, dated September 22, 2005 (which we referred to in the NPRM as the appropriate source of service information for accomplishing the required actions), does not contain information for inspecting areas where a repair doubler has already been installed. JAL asks that we postpone issuing the AD until an inspection method for the repaired area is incorporated into the service bulletin. We disagree with the request to postpone the AD. The condition requiring repairs may be unique on each airplane. Therefore, approval of instructions for inspecting areas where a repair doubler has been installed may be obtained using a method approved in accordance with the procedures specified in paragraph (i) of this AD. As an unsafe condition has been identified, it is not appropriate to delay issuing this AD for this reason. We have not changed the AD in this regard. Request To Add a Grace Period for Modification JAL also requests that we add an additional grace period to paragraph (h) of the NPRM by adding the words ‘‘or 18 months after the issue of the modification service bulletin.’’ (The compliance time specified in that paragraph would then read: ‘‘Before the airplane accumulates 35,000 total flight cycles or within 18 months after the effective date of this AD or within 18 months after the issue of the modification service bulletin, whichever occurs later.’’) The commenter states that the modification method is not yet available to operators. We disagree with the request to add an additional grace period. We have identified an unsafe condition that is associated with widespread fatigue damage (WFD). A modification within the compliance times specified in paragraph (h) of this AD is necessary for the continued airworthiness of the airplane beyond 35,000 total flight cycles, and it is not appropriate to delay issuing this AD for these airplanes. Repetitive inspections alone will not ensure an acceptable level of safety for airplanes beyond 35,000 total flight cycles, considering the failure E:\FR\FM\29JAR1.SGM 29JAR1

Airworthiness Directives; Boeing Model 767-200 and -300 Series 
Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD) that applies to certain Boeing Model 767-200, -300, and -300F 
series airplanes. That AD currently requires an inspection of visually 
accessible areas for indications of overheating of the heater tape 
attached to the potable water fill and drain lines in the forward and 
aft cargo compartments, exposed foam insulation or missing or damaged 
protective tape around the potable water fill and drain lines, and 
debris or contaminants on or near the potable water fill and drain 
lines. That AD also requires corrective action, as necessary. This new 
AD requires repetitive inspections of the forward and aft cargo 
compartments, as applicable, for discrepancies of the potable water 
supply and gray water drain lines; and applicable corrective actions if 
necessary. This AD also requires replacing the heater tapes on the 
potable water supply and gray water drain lines of the forward and aft 
cargo compartments, as applicable, with new ribbon heaters, or 
deactivating and removing any defective heater tape and wrapping the 
drain line with foam insulation; either action ends the repetitive 
inspections. This AD results from a report of a fire in the aft cargo 
compartment. We are issuing this AD to prevent overheating of the 
heater tape on potable water fill and drain lines, which may ignite 
accumulated debris or contaminants on or near the potable water fill 
and drain lines, resulting in a fire in the airplane.

DATES: This AD becomes effective March 5, 2007.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of March 5, 
2007.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that supersedes AD 2002-11-11, amendment 
39-12772 (67 FR 39265, June 7, 2002). The existing AD applies to 
certain Boeing Model 767-200, -300, and -300F series airplanes. That 
NPRM was published in the Federal Register on June 30, 2006 (71 FR 
37507). That NPRM proposed to require repetitive inspections of the 
forward and aft cargo compartments, as applicable, for discrepancies of 
the potable water supply and gray water drain lines; and applicable 
corrective actions if necessary. That NPRM also proposed to require 
replacing the heater tapes on the potable water supply and gray water 
drain lines of the forward and aft cargo compartments, as applicable, 
with new ribbon heaters, which would end the repetitive inspections.

Comments

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

Request To Permit Alternative Method of Compliance

    Boeing requests that we permit an alternative method of compliance 
for the terminating action described in the NPRM. Boeing states that 
Boeing Service Bulletin 767-30A0038, Revision 2, dated February 23, 
2006, describes procedures for deactivating and removing the heater 
tapes of certain gray water drain lines and wrapping the drain lines 
with foam insulation. Boeing therefore requests that we revise the 
summary and paragraph (h), Terminating Action, of the NPRM to state 
that the alternative action described here is acceptable as a 
terminating action for the requirements of the AD.
    We agree for the reasons stated. Accordingly, we have revised the 
summary of the AD, revised paragraph (h) of the AD to include new 
paragraphs (h)(1) and (h)(2), and removed paragraph identifiers (1) and 
(2) from Table 2 of the AD. We have also revised the Costs of 
Compliance section of the AD to present the estimated costs for 
deactivation and removal of the heating tapes and installation of foam 
insulation. These actions neither increase the economic burden on any 
operator nor increase the scope of the AD.

Request To Clarify Costs of Compliance

    Boeing requests that we clarify the Costs of Compliance section of 
the NPRM. Boeing states that the Estimated Costs table is not clear and 
asserts that the time estimated for performing the inspections should 
be ``2 or 3'' work hours. Boeing further asserts that Boeing Service 
Bulletin 767-30A0038 specifies ``between 4.75 and 11 work hours'' to 
perform the heater tape replacements. Although Boeing made no specific 
request, we infer that Boeing wishes us to revise the Costs of 
Compliance section to more closely reflect the estimated costs 
specified in the service bulletin.
    We partially agree. We concur that the time estimated for 
performing the inspections should be 2 or 3 work hours, as shown in the 
Estimated Costs table. However, the statement that ``between 4.75 and 
11 work hours'' are required to replace the heater tapes does not 
accurately reflect the service information we have reviewed. The 
service bulletin provides an estimate of between 4.75 and 11 work hours 
to gain access, perform inspections, replacements and tests, and close 
access. Typically, the costs specified in an AD are only the direct 
costs of the specific actions required by the AD. Therefore, the 
figures shown in the Estimated Costs table of this AD do not include 
the time to gain and close access or perform testing. Further, the 
remaining work hours specified to do the direct actions are divided 
into two parts: one part to perform the inspections and one part to 
replace the ribbon heater or to remove the heater and install foam 
insulation. We have made no changes to the AD in regard to these 
comments.

Comment Regarding Applicability

    A private citizen states that the NPRM does not apply to Model 767 
freighter airplanes.
    We agree. The AD does not apply to Model 767-300F or -400ER series 
airplanes (freighters), but only to Model 767-200 and -300 series 
airplanes, as stated in the NPRM. No change is needed to the AD in this 
regard.

Request for Posting of Service Information

    The Modification and Replacement Parts Association (MARPA), 
requests that we revise our procedures for incorporation by reference 
(IBR) of service information in ADs. MARPA states that, as an AD is a 
public regulatory instrument, it can not rely upon private writings. 
MARPA asserts that such IBR documents lose any proprietary, protected 
status they originally had and become public documents and, therefore, 
that they must be published in the Docket Management System (DMS), 
keyed to the action that incorporates them. MARPA addresses the stated 
purpose of the Federal Register IBR method, brevity, which is intended 
to relieve the Federal Register of needlessly publishing documents 
already supplied to affected individuals: owners and operators of 
affected aircraft. MARPA asserts that ``affected individuals'' are no 
longer merely owners and operators, but, since most aircraft 
maintenance is now performed by specialty shops, that a new class of 
affected individuals has emerged. This new class includes maintenance 
and repair organizations, component servicing and repair shops, parts 
purveyors and distributors, and organizations manufacturing or 
servicing alternatively certified parts under 14 CFR 21.303 (PMA). 
Further, MARPA contends that the concept of brevity is now nearly 
archaic as most documents are kept in electronic files. MARPA therefore 
requests that IBR documents be incorporated by reference into the 
regulatory instrument and posted in the DMS docket for the applicable 
AD.
    We acknowledge MARPA's comments. The Office of the Federal Register 
(OFR) requires that documents that are necessary to accomplish the 
requirements of the AD be incorporated by reference during the final 
rule phase of rulemaking. This final rule incorporates by reference the 
document

[[Page 3932]]

necessary for the accomplishment of the requirements mandated by this 
AD. Further, we point out that while documents that are incorporated by 
reference do become public information, they do not lose their 
copyright protection. For that reason, we advise the public to contact 
the manufacturer to obtain copies of the referenced service 
information.
    In regard to MARPA's request to post service documents on the 
Department of Transportation's DMS, we are currently in the process of 
reviewing issues surrounding the posting of service documents on the 
DMS as part of an AD docket. Once we have thoroughly examined all 
aspects of this issue and have made a final determination, we will 
consider whether our current practice needs to be revised. No change to 
the final rule is necessary in response to this comment.

Request for Standardized Directorate Policies

    MARPA requests standardized directorate policies, asserting that 
another directorate has already given a blanket parts manufacturer 
approval (PMA) by stating in published rules that ``FAA-approved 
equivalent parts'' may be used. MARPA contends that, by not using 
similar language, we are not in compliance with Executive Order 12866 
or proposed FAA order 8040.2. MARPA asserts that for us to not include 
similar blanket language at the earliest possible time could work to 
our disadvantage legally.
    We recognize the need for standardization on this issue and 
currently are in the process of reviewing issues that address PMAs at 
the national level. However, the Transport Airplane Directorate 
considers that to delay this particular 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.

Conclusion

    We have carefully reviewed the available data, including the 
comments that have been 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

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.
