VerDate Aug<31>2005 14:28 Mar 03, 2006 Jkt 208001 A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an airworthiness directive (AD) that is applicable to all Boeing Model 747SP, 747SR, 747–100, –100B, –100B SUD, –200B, –200C, –200F, and –300 series airplanes, was published as a supplemental notice of proposed rulemaking (NPRM) in the Federal Register on August 23, 2005 (70 FR 49207). That action proposed to require modification of the escape slide/raft pack assembly and cable release sliders, as applicable. SUPPLEMENTARY INFORMATION: Comments Interested persons have been afforded an opportunity to participate in the making of this amendment. Due consideration has been given to the comments received. Request To Change Paragraph (a)(1) One commenter, the manufacturer, disagrees with the language specified in paragraph (a)(1) of the supplemental NPRM as written. The commenter reiterates that paragraph and states that it disagrees with the content. The commenter states that, if Boeing Service Bulletin 747–25–2666, Revision 2, dated April 24, 2003; and Goodrich Service Bulletin 25–238, Revision 1, dated January 31, 2003; have been incorporated, the Door 3 ramp slide pack (two-piece slide) will have been replaced with a one-piece slide pack, which does not have the cable assemblies addressed by Boeing Service Bulletin 747–25–3274, Revision 3, dated December 16, 2004 (referenced in the supplemental NPRM for accomplishing certain actions). The one-piece slides installed by Goodrich Service Bulletin 25–238 are specified in that service bulletin. We agree with the commenter and have revised paragraph (a)(1) (reidentified as paragraph (a)(2) of the final rule) as follows: ‘‘For airplanes on which the modification of Door 3, as specified in Boeing Special Attention Service Bulletin 747–25–2666, Revision 2; and Goodrich Service Bulletin 25– 238, Revision 1; has been accomplished: No further action is required for Door 3 only.’’ Request To Exclude Certain Airplanes From the Applicability One commenter asks that we change the applicability section specified in the supplemental NPRM. The commenter states that not all the airplanes listed in the applicability section are equipped with the affected escape slide/raft pack assembly components. The commenter notes that it operates several Model PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 747–100 series airplanes that do not have the affected equipment installed. The commenter adds that those airplanes were originally designed and manufactured with the cool gas generator escape slide inflation system, which does not include the affected escape slide/raft pack assembly components. Additionally, Boeing Special Attention Service Bulletin 747– 25–3274 does not include those airplanes in the effectivity, nor does it include procedures for those airplanes. The commenter asks that the applicability section be changed to be similar to that in AD 2004–03–17, amendment 39–13461 (69 FR 6536, February 11, 2004), which includes both the affected airplane models and those equipped with affected components. We agree with the commenter and have changed the applicability section in this AD to exclude those airplanes that do not have the affected equipment installed, as follows: ‘‘Model 747SP, 747SR, 747–100, –100B, –100B SUD, –200B, –200C, –200F, and –300 series airplanes; certificated in any category; equipped with an escape slide/raft pack assembly; as identified in Boeing Special Attention Service Bulletin 747– 25–3274, Revision 3, dated December 16, 2004.’’ Another commenter asks that the final rule include a statement to the effect that Model 747 airplanes converted to the all-cargo configuration by any FAAapproved modification are excluded from accomplishing the modification of the slide required by the AD on any main door that has had the slide removed. The commenter suggests that this would reduce the number of requests submitted to the FAA for alternative methods of compliance (AMOC), thus reducing the use of FAA resources. The commenter also states that airplanes on which the escape slides for the upper deck crew door have been removed, in accordance with Supplemental Type Certificate (STC) ST01539SE, should be excluded from the applicability section of the AD. We agree with the commenter that airplanes with an FAA-approved modification of the main doors that have the slides removed are not affected by the unsafe condition and should not be subject to this AD. Therefore, we have changed the applicability section in this AD to specify airplanes ‘‘equipped with an escape slide raft/ pack assembly’; which, in turn, excludes airplanes on which the escape slides for the upper deck crew door have been removed in accordance with STC ST01539SE. E:\FR\FM\06MRR1.SGM 06MRR1 Federal Register / Vol. 71, No. 43 / Monday, March 6, 2006 / Rules and Regulations Revised Service Information After the supplemental NPRM was issued, Boeing released Service Bulletin 747–25–3274, Revision 4, dated February 23, 2006. We have reviewed the service bulletin and it is substantially similar to Revision 3, which was referred to in the supplemental NPRM as the acceptable source of service information for accomplishing the actions specified in paragraph (a)(1). We have revised paragraph (a)(1) of this AD to refer to Revision 4 of the service bulletin as the acceptable source of service information for accomplishing the actions, and to give credit for accomplishing the actions specified in Revision 3 before the effective date of this AD. Clarification of AMOC Paragraph We have revised this action to clarify the appropriate procedure for notifying the principal inspector before using any approved AMOC on any airplane to which the AMOC applies. Conclusion After careful review of the available data, including the comments noted above, the FAA has determined that air safety and the public interest require the adoption of the rule with the changes previously described. These changes will neither increase the economic burden on any operator nor increase the scope of the AD. hsrobinson on PROD1PC70 with RULES Cost Impact There are approximately 592 airplanes of the affected design in the worldwide fleet. We estimate that 187 airplanes of U.S. registry will be affected by this AD. It will take approximately 2 work hours per escape slide to accomplish the new modification of the escape slide/ raft pack assembly, at an average labor rate of $65 per work hour. Required parts will cost between $8,354 and $30,688 per airplane. Based on these figures, the cost impact of the modification of the escape slide/raft pack assembly required by this AD on U.S. operators is estimated to be between $1,586,508 and $5,762,966, or between $8,484 and $30,818 per airplane. Should an operator be required to accomplish the overhaul of the cable release sliders, it will take approximately 2 work hours to accomplish the overhaul, at an average labor rate of $65 per work hour. Required parts cost will be negligible. Based on these figures, the cost impact of the overhaul of the cable release sliders in this AD on U.S. operators is VerDate Aug<31>2005 14:28 Mar 03, 2006 Jkt 208001 estimated to be $130 per escape slide and $260 per airplane. Should an operator be required to accomplish the replacement of the cable release sliders, it will take approximately 1 work hour to accomplish the replacement, at an average labor rate of $65 per work hour. Required parts will cost approximately $2,940 per escape slide. Based on these figures, the cost impact of the replacement of the cable release sliders in this AD on U.S. operators is estimated to be $3,005 per escape slide or $6,010 per airplane. The cost impact figures discussed above are based on assumptions that no operator has yet accomplished any of the requirements of this AD action, and that no operator would accomplish those actions in the future if this AD were not adopted. The cost impact figures discussed in AD rulemaking actions represent only the time necessary to perform the specific actions actually required by the AD. These figures typically do not include incidental costs, such as the time required to gain access and close up, planning time, or time necessitated by other administrative actions. 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 Impact The regulations adopted herein 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. Therefore, it is determined that this final rule does not have federalism implications under Executive Order 13132. PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 11157 For the reasons discussed above, I certify that this action (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.

Final rule. AGENCY: ACTION: SUMMARY: This final rule sets forth the minimum qualifications an individual annuity broker must meet in order to be included on the list of annuity brokers, established by the Attorney General, for the provision of annuity brokerage services in connection with structured settlements entered into by the United States. The final rule also sets forth the procedures that annuity brokers must follow in order to be included on the list. DATES: This rule is effective on April 5, 2006. FOR FURTHER INFORMATION CONTACT: Roger D. Einerson, Assistant Director, Torts Branch, FTCA Staff, P.O. Box 888, Benjamin Franklin Station, Washington, DC 20044. 202–616–4250. SUPPLEMENTARY INFORMATION: This rule implements section 11015(a) of Public Law 107–273, the 21st Century Department of Justice Appropriations Act, which provides: ‘‘Not later than 6 months after the date of enactment of this Act, the Attorney General shall establish a list of annuity brokers who meet minimum qualifications for providing annuity brokerage services in connection with structured settlements entered by the United States.’’ The Attorney General published an interim rule implementing section 11015(a) on April 15, 2003, at 68 FR 18119. Public comments were due by no later than July 14, 2003. On May 1, 2003, the Department of Justice transmitted to all United States Attorneys the first list of annuity brokers who had submitted timely Declarations demonstrating that they met the minimum qualifications for providing annuity brokerage services in connection with structured settlements PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 entered into by the United States. The Department has transmitted new calendar-year lists since the original calendar-year list, as well as updates of each calendar-year list. The Department of Justice received four written comments and a number of oral comments in response to the interim rule. The comments were received from annuity brokers, an association representing annuity brokers, a federal agency, and several United States Attorneys’ offices. The written comments were, for the most part, unrelated to either the minimum qualifications established by the Attorney General pursuant to section 11015(a) of Public Law 107–273, or the mandatory procedures that annuity brokers must follow in order to be included on the list or any updated list. The oral comments related almost exclusively to the organization of the May 1, 2003 list that was transmitted to all United States Attorneys’ offices, the effective date of that list, and the application of that list. Rather than respond to each comment individually, the Department will respond to the subject matter of the concerns raised. The Department of Justice has considered the comments and responds as follows: 1. One commenter suggested that the minimum qualifications established by the Attorney General should be more stringent in order to better protect the interests of the United States. The commenter suggested that an annuity broker should be required to be licensed with more than one annuity company in order to meet minimum qualifications, so that the United States could take advantage of competitive annuity pricing from more than one annuity company. The commenter also suggested that the minimum qualifications should require an annuity broker to be licensed with companies that qualify under the Uniform Periodic Payment of Judgments Act. While these may be valid considerations in selecting an annuity broker for a particular case, the qualifications established by the Attorney General, pursuant to section 11015(a) of Public Law 107–273, were only minimum qualifications. The enhanced qualifications suggested by the commenter go beyond minimum qualifications. The United States Attorneys or their designees may consider additional criteria in selecting a broker, including those suggested by the commenter. However, these suggestions will not be incorporated into the final rule as mandatory minimum qualifications. 2.

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to all Boeing Model 747SP, 747SR, 747-100, -100B, -100B SUD, 
-200B, -200C, -200F, and -300 series airplanes, that requires 
modification of the escape slide/raft pack assembly and cable release 
sliders, as applicable. The actions specified by this AD are intended 
to prevent improper deployment of the escape slide/raft or blockage of

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to include an airworthiness 
directive (AD) that is applicable to all Boeing Model 747SP, 747SR, 
747-100, -100B, -100B SUD, -200B, -200C, -200F, and -300 series 
airplanes, was published as a supplemental notice of proposed 
rulemaking (NPRM) in the Federal Register on August 23, 2005 (70 FR 
49207). That action proposed to require modification of the escape 
slide/raft pack assembly and cable release sliders, as applicable.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. Due consideration has been given to 
the comments received.

Request To Change Paragraph (a)(1)

    One commenter, the manufacturer, disagrees with the language 
specified in paragraph (a)(1) of the supplemental NPRM as written. The 
commenter reiterates that paragraph and states that it disagrees with 
the content. The commenter states that, if Boeing Service Bulletin 747-
25-2666, Revision 2, dated April 24, 2003; and Goodrich Service 
Bulletin 25-238, Revision 1, dated January 31, 2003; have been 
incorporated, the Door 3 ramp slide pack (two-piece slide) will have 
been replaced with a one-piece slide pack, which does not have the 
cable assemblies addressed by Boeing Service Bulletin 747-25-3274, 
Revision 3, dated December 16, 2004 (referenced in the supplemental 
NPRM for accomplishing certain actions). The one-piece slides installed 
by Goodrich Service Bulletin 25-238 are specified in that service 
bulletin.
    We agree with the commenter and have revised paragraph (a)(1) (re-
identified as paragraph (a)(2) of the final rule) as follows: ``For 
airplanes on which the modification of Door 3, as specified in Boeing 
Special Attention Service Bulletin 747-25-2666, Revision 2; and 
Goodrich Service Bulletin 25-238, Revision 1; has been accomplished: No 
further action is required for Door 3 only.''

Request To Exclude Certain Airplanes From the Applicability

    One commenter asks that we change the applicability section 
specified in the supplemental NPRM. The commenter states that not all 
the airplanes listed in the applicability section are equipped with the 
affected escape slide/raft pack assembly components. The commenter 
notes that it operates several Model 747-100 series airplanes that do 
not have the affected equipment installed. The commenter adds that 
those airplanes were originally designed and manufactured with the cool 
gas generator escape slide inflation system, which does not include the 
affected escape slide/raft pack assembly components. Additionally, 
Boeing Special Attention Service Bulletin 747-25-3274 does not include 
those airplanes in the effectivity, nor does it include procedures for 
those airplanes. The commenter asks that the applicability section be 
changed to be similar to that in AD 2004-03-17, amendment 39-13461 (69 
FR 6536, February 11, 2004), which includes both the affected airplane 
models and those equipped with affected components.
    We agree with the commenter and have changed the applicability 
section in this AD to exclude those airplanes that do not have the 
affected equipment installed, as follows: ``Model 747SP, 747SR, 747-
100, -100B, -100B SUD, -200B, -200C, -200F, and -300 series airplanes; 
certificated in any category; equipped with an escape slide/raft pack 
assembly; as identified in Boeing Special Attention Service Bulletin 
747-25-3274, Revision 3, dated December 16, 2004.''
    Another commenter asks that the final rule include a statement to 
the effect that Model 747 airplanes converted to the all-cargo 
configuration by any FAA-approved modification are excluded from 
accomplishing the modification of the slide required by the AD on any 
main door that has had the slide removed. The commenter suggests that 
this would reduce the number of requests submitted to the FAA for 
alternative methods of compliance (AMOC), thus reducing the use of FAA 
resources. The commenter also states that airplanes on which the escape 
slides for the upper deck crew door have been removed, in accordance 
with Supplemental Type Certificate (STC) ST01539SE, should be excluded 
from the applicability section of the AD.
    We agree with the commenter that airplanes with an FAA-approved 
modification of the main doors that have the slides removed are not 
affected by the unsafe condition and should not be subject to this AD. 
Therefore, we have changed the applicability section in this AD to 
specify airplanes ``equipped with an escape slide raft/pack assembly'; 
which, in turn, excludes airplanes on which the escape slides for the 
upper deck crew door have been removed in accordance with STC 
ST01539SE.

[[Page 11157]]

Revised Service Information

    After the supplemental NPRM was issued, Boeing released Service 
Bulletin 747-25-3274, Revision 4, dated February 23, 2006. We have 
reviewed the service bulletin and it is substantially similar to 
Revision 3, which was referred to in the supplemental NPRM as the 
acceptable source of service information for accomplishing the actions 
specified in paragraph (a)(1). We have revised paragraph (a)(1) of this 
AD to refer to Revision 4 of the service bulletin as the acceptable 
source of service information for accomplishing the actions, and to 
give credit for accomplishing the actions specified in Revision 3 
before the effective date of this AD.

Clarification of AMOC Paragraph

    We have revised this action to clarify the appropriate procedure 
for notifying the principal inspector before using any approved AMOC on 
any airplane to which the AMOC applies.

Conclusion

    After careful review of the available data, including the comments 
noted above, the FAA has determined that air safety and the public 
interest require the adoption of the rule with the changes previously 
described. These changes will neither increase the economic burden on 
any operator nor increase the scope of the AD.

Cost Impact

    There are approximately 592 airplanes of the affected design in the 
worldwide fleet. We estimate that 187 airplanes of U.S. registry will 
be affected by this AD.
    It will take approximately 2 work hours per escape slide to 
accomplish the new modification of the escape slide/raft pack assembly, 
at an average labor rate of $65 per work hour. Required parts will cost 
between $8,354 and $30,688 per airplane. Based on these figures, the 
cost impact of the modification of the escape slide/raft pack assembly 
required by this AD on U.S. operators is estimated to be between 
$1,586,508 and $5,762,966, or between $8,484 and $30,818 per airplane.
    Should an operator be required to accomplish the overhaul of the 
cable release sliders, it will take approximately 2 work hours to 
accomplish the overhaul, at an average labor rate of $65 per work hour. 
Required parts cost will be negligible. Based on these figures, the 
cost impact of the overhaul of the cable release sliders in this AD on 
U.S. operators is estimated to be $130 per escape slide and $260 per 
airplane.
    Should an operator be required to accomplish the replacement of the 
cable release sliders, it will take approximately 1 work hour to 
accomplish the replacement, at an average labor rate of $65 per work 
hour. Required parts will cost approximately $2,940 per escape slide. 
Based on these figures, the cost impact of the replacement of the cable 
release sliders in this AD on U.S. operators is estimated to be $3,005 
per escape slide or $6,010 per airplane.
    The cost impact figures discussed above are based on assumptions 
that no operator has yet accomplished any of the requirements of this 
AD action, and that no operator would accomplish those actions in the 
future if this AD were not adopted. The cost impact figures discussed 
in AD rulemaking actions represent only the time necessary to perform 
the specific actions actually required by the AD. These figures 
typically do not include incidental costs, such as the time required to 
gain access and close up, planning time, or time necessitated by other 
administrative actions.

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 Impact

    The regulations adopted herein 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. Therefore, it 
is determined that this final rule does not have federalism 
implications under Executive Order 13132.
    For the reasons discussed above, I certify that this action (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. A final evaluation has been prepared for this action 
and it is contained in the Rules Docket. A copy of it may be obtained 
from the Rules Docket at the location provided under the caption 
ADDRESSES.
