SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR Part 39 with an AD for certain Boeing Model 747– 100, 747–100B, 747–200B, 747–300, 747–400, 747–400D, 747SR, and 747SP series airplanes. That action, published in the Federal Register on November 5, 2004 (69 FR 64537), proposed to require replacing or modifying the control panels for the galley cart lift and modifying related electrical cable assemblies, as applicable. Comments We provided the public the opportunity to participate in the development of this AD. We have PO 00000 Frm 00021 Fmt 4700 Sfmt 4700 28795 considered the comments that have been submitted on the proposed AD. Request To Clarify Prompt Language and Statement of Unsafe Condition One commenter, the manufacturer, requests that we clarify the statements in the Summary and paragraph (d) of the proposed AD of what prompted the proposed AD and clarifying the unsafe condition. The commenter suggests we can do this by explaining the role of a disabled or malfunctioning safety interlock door switch of the galley cart lift. The commenter states that the existing statements do not clearly describe the string of events relevant to the unexpected movement of the galley cart lift. We partially agree. The statement of what prompted the proposed AD would be clearer if we included the role of a disabled or malfunctioning safety interlock door switch of the galley cart lift. We have changed the Summary and paragraph (d) of the final rule to include this role. However, we do not agree that the statement of the unsafe condition should include the role of a disabled or malfunctioning safety interlock door switch. The purpose of this AD is to prevent the galley cart lift from being activated from the other deck control panel, regardless of whether the safety interlock switch is functional or not. We have not changed the final rule in this regard. Request To Clarify Discussion and Relevant Service Information The same commenter requests that the Discussion and Relevant Service Information sections of the proposed AD be revised to include the role of a disabled or malfunctioning safety interlock door switch. The commenter states the same reason as before. We do not agree. The existing sections are intended to describe the unsafe condition and are adequate as written. Further, the Discussion and Relevant Service Information sections are not carried forward into the final rule. No change is needed in this regard. Request To Specify Increased Personnel Training and Oversight The same commenter requests that the Relevant Service Information section be revised by adding Boeing Alert Service Bulletin 747–25A3116, which specifies installation of additional cautionary placarding to the galley lift doors. Further, the commenter states that increased levels of operational training and oversight would best minimize injury of personnel who operate the galley cart lift. The commenter states E:\FR\FM\19MYR1.SGM 19MYR1 28796 Federal Register / Vol. 70, No. 96 / Thursday, May 19, 2005 / Rules and Regulations these actions will have the greatest effect in reducing potential injuries. We do not agree. The commenter’s proposed revision introduces the replacement and/or relocation of warning placards as well as additional recommended actions involving crew training and oversight that are not required by this AD. Additional crew training and oversight and additional placards may be helpful but we have determined, in this case, that the actions mandated by this AD are sufficient to address the unsafe condition. Further, as already stated, the Relevant Service Information section is not carried forward into the final rule. No change is needed in this regard. Conclusion We have carefully reviewed the available data, including the comments that have been submitted, 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 600 airplanes of the affected design worldwide. This AD will affect about 66 airplanes of U.S. registry. About 22 Model 747–100, 747–100B, 747–200B, 747–300, 747SR, and 747SP series airplanes of U.S. registry will be affected by the required actions. It will take about 7 work hours per airplane to do the required actions, at an average labor rate of $65 per work hour. Required parts will cost about $143 per airplane. Based on these figures, the estimated cost of the AD for these U.S. operators is $13,156, or $598 per airplane. About 44 Model 747–400 and 747– 400D series airplanes of U.S. registry will be affected by the required actions. It will take about 2 work hours per airplane to do the required actions, at an average labor rate of $65 per work hour. Required parts will cost about $4,934 per airplane. Based on these figures, the estimated cost of the AD for these U.S. operators is $222,816, or $5,064 per airplane. Authority for This Rulemaking 15:30 May 18, 2005 Jkt 205001 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. See the ADDRESSES section for a location to examine the regulatory evaluation. Effective Date (a) This AD becomes effective June 23, 2005. Affected ADs (b) None. Applicability (c) This AD applies to certain Boeing Model 747–100, 747–100B, 747–200B, 747– 300, 747SR, and 747SP series airplanes, as identified in Boeing Alert Service Bulletin 747–25A3287, Revision 2, dated September 4, 2003; and Model 747–400 and 747–400D series airplanes, as identified in Boeing Service Bulletin 747–25A3187, Revision 2, dated January 27, 2000; certificated in any category. Unsafe Condition (d) This AD was prompted by reports of injuries to catering personnel and flight attendants who were loading or unloading galley carts on one deck when, due to a disabled or malfunctioning safety interlock door switch, the galley cart lift unexpectedly moved when it was activated from the control panel on the other deck. We are issuing this AD to ensure that the galley cart lift can be sent only from the deck on which it is in use, which will prevent unexpected movement of the cart lift that could result in possible injury to catering personnel or flight attendants. 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. Replacement/Modification of Control Panel PART 39—AIRWORTHINESS DIRECTIVES (f) Within 18 months after the effective date of this AD, accomplish the actions required by paragraph (f)(1) or (f)(2) of this AD, as applicable. (1) For Model 747–400 and 747–400D series airplanes: Replace the main and upper deck control panels for the galley cart lift with new or modified control panels by doing all the actions specified in Boeing Service Bulletin 747–25A3187, Revision 2, dated January 27, 2000. (2) For Model 747–100, 747–100B, 747– 200B, 747–300, 747SR, and 747SP series airplanes: Modify the main and upper deck control panels and related cable assemblies for the galley cart lift by doing all the actions specified in Boeing Alert Service Bulletin 747–25A3287, Revision 2, dated September 4, 2003. 1. The authority citation for part 39 continues to read as follows: Actions Accomplished Per Previous Issue of Service Bulletin List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: I I Authority: 49 U.S.C. 106(g), 40113, 44701. 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. VerDate jul<14>2003 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. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): I 2005–10–19 Boeing: Amendment 39–14096. Docket No. FAA–2004–19532; Directorate Identifier 2004–NM–87–AD.

ACTION: Final rule. AGENCY: SUMMARY: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 777– 200 and –300 series airplanes, that requires modification of the bolt holes of the lower side of the body splice tchord common to the paddle fittings of the lower wing panel. The modification includes performing a high frequency eddy current inspection of the fastener VerDate jul<14>2003 15:30 May 18, 2005 Jkt 205001 holes for cracks, repairing the hole if necessary, and replacing the fasteners with new inconel bolts. This action is necessary to prevent fatigue cracks in the lower t-chord at the bolt holes common to the paddle fittings that could result in fractures of one or more of the t-chord segments, which could lead to detachment of the lower wing panel and consequent loss of the wing. This action is intended to address the identified unsafe condition. DATES: Effective June 23, 2005. The incorporation by reference of a certain publication listed in the regulations is approved by the Director of the Federal Register as of June 23, 2005. ADDRESSES: The service information referenced in this AD may be obtained from Boeing Commercial Airplanes, P.O. Box 3707, Seattle, Washington 98124–2207. This information may be examined at the Federal Aviation Administration (FAA), Transport Airplane Directorate, Rules Docket, 1601 Lind Avenue, SW., Renton, Washington.

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 certain Boeing Model 777–200 and –300 series airplanes was published in the Federal Register on June 16, 2004 (69 FR 33595). That action proposed to require modification of the bolt holes of the lower side of the body splice t-chord common to the paddle fitting of the lower wing panel. The modification includes performing a high frequency eddy current inspection of the fastener hole for cracks, repairing the hole if necessary, and replacing the fasteners with new inconel bolts. 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. Agreement With Proposed Modification Two commenters generally agree with the proposal to mandate the modification specified in the proposed AD instead of allowing an option to accomplish repetitive inspections. One commenter notes that the work hours PO 00000 Frm 00023 Fmt 4700 Sfmt 4700 28797 needed to do the modification are comparable to the work hours needed to do the inspection. Request To Revise Compliance Times Based on ‘‘Sliding Scale’’ Equation One commenter, the manufacturer, requests that the compliance times specified in paragraph (a) of the proposed AD be revised to be based on a ‘‘sliding scale’’ equation. The commenter states that the ‘‘sliding scale’’ equation determines compliance times based on an evaluation of the total flight cycles associated with the total flight hours. The commenter notes that the compliance times specified in paragraph (a) of the proposed AD were found to be adversely affecting operators who use airplanes on long missions. The commenter states that some airplanes are reaching the 60,000 total flight-hour threshold before reaching 8,000 total flight cycles. The commenter further contends that the cracks addressed in the proposed AD are largely a function of flight cycles, not flight hours, and that, for these airplanes, the proposed AD would mandate the modification before it is necessary. We agree with the commenter to revise the compliance times specified in paragraph (a) of the final rule. However, we do not agree with the compliance time based on a ‘‘sliding scale’’ equation proposed by the commenter. That proposed compliance time would expand the compliance envelope for airplanes utilized on long missions but would reduce the compliance time for airplanes near the 20,000 flight-cycle and 60,000 flight-hour compliance envelope. We held an ex-parte meeting with the commenter to discuss its proposed compliance time. The commenter presented data in support of a new ‘‘sliding scale’’ equation for the compliance time that differed from the equation proposed in the manufacturer’s comment. The new proposed compliance time simply expanded the compliance time specified in the proposed AD. The new data were accepted and subsequently incorporated into Boeing Service Bulletin 777– 57A0040, Revision 2, dated February 24, 2005. Boeing Service Bulletin 777– 57A0040, Revision 1, dated July 10, 2003, was referenced as the appropriate source of service information for accomplishing the proposed actions. Revision 2 of the service bulletin contains the same actions for doing the modification as Revision 1 of the service bulletin. We have revised paragraph (a) of the final rule to reference Revision 2 of the E:\FR\FM\19MYR1.SGM 19MYR1

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Boeing Model 747-100, 747-100B, 747-200B, 747-300, 747-400, 
747-400D, 747SR, and 747SP series airplanes. This AD requires replacing 
or modifying the control panels for the galley cart lift and modifying 
related electrical cable assemblies, as applicable. This AD is prompted 
by reports of injuries to catering personnel and flight attendants who 
were loading or unloading galley carts on one deck when, due to a 
disabled or malfunctioning safety interlock door switch, the galley 
cart lift unexpectedly moved when it was activated from the control 
panel on the other deck. We are issuing this AD to ensure that the 
galley cart lift can be sent only from the deck on which it is in use, 
which will prevent unexpected movement of the cart lift that could 
result in possible injury to catering personnel or flight attendants.

DATES: This AD becomes effective June 23, 2005.
    The incorporation by reference of certain publications listed in 
the AD is approved by the Director of the Federal Register as of June 
23, 2005.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR Part 39 
with an AD for certain Boeing Model 747-100, 747-100B, 747-200B, 747-
300, 747-400, 747-400D, 747SR, and 747SP series airplanes. That action, 
published in the Federal Register on November 5, 2004 (69 FR 64537), 
proposed to require replacing or modifying the control panels for the 
galley cart lift and modifying related electrical cable assemblies, as 
applicable.

Comments

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

Request To Clarify Prompt Language and Statement of Unsafe Condition

    One commenter, the manufacturer, requests that we clarify the 
statements in the Summary and paragraph (d) of the proposed AD of what 
prompted the proposed AD and clarifying the unsafe condition. The 
commenter suggests we can do this by explaining the role of a disabled 
or malfunctioning safety interlock door switch of the galley cart lift. 
The commenter states that the existing statements do not clearly 
describe the string of events relevant to the unexpected movement of 
the galley cart lift.
    We partially agree. The statement of what prompted the proposed AD 
would be clearer if we included the role of a disabled or 
malfunctioning safety interlock door switch of the galley cart lift. We 
have changed the Summary and paragraph (d) of the final rule to include 
this role.
    However, we do not agree that the statement of the unsafe condition 
should include the role of a disabled or malfunctioning safety 
interlock door switch. The purpose of this AD is to prevent the galley 
cart lift from being activated from the other deck control panel, 
regardless of whether the safety interlock switch is functional or not. 
We have not changed the final rule in this regard.

Request To Clarify Discussion and Relevant Service Information

    The same commenter requests that the Discussion and Relevant 
Service Information sections of the proposed AD be revised to include 
the role of a disabled or malfunctioning safety interlock door switch. 
The commenter states the same reason as before.
    We do not agree. The existing sections are intended to describe the 
unsafe condition and are adequate as written. Further, the Discussion 
and Relevant Service Information sections are not carried forward into 
the final rule. No change is needed in this regard.

Request To Specify Increased Personnel Training and Oversight

    The same commenter requests that the Relevant Service Information 
section be revised by adding Boeing Alert Service Bulletin 747-25A3116, 
which specifies installation of additional cautionary placarding to the 
galley lift doors. Further, the commenter states that increased levels 
of operational training and oversight would best minimize injury of 
personnel who operate the galley cart lift. The commenter states

[[Page 28796]]

these actions will have the greatest effect in reducing potential 
injuries.
    We do not agree. The commenter's proposed revision introduces the 
replacement and/or relocation of warning placards as well as additional 
recommended actions involving crew training and oversight that are not 
required by this AD. Additional crew training and oversight and 
additional placards may be helpful but we have determined, in this 
case, that the actions mandated by this AD are sufficient to address 
the unsafe condition. Further, as already stated, the Relevant Service 
Information section is not carried forward into the final rule. No 
change is needed in this regard.

Conclusion

    We have carefully reviewed the available data, including the 
comments that have been submitted, 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 600 airplanes of the affected design worldwide. 
This AD will affect about 66 airplanes of U.S. registry.
    About 22 Model 747-100, 747-100B, 747-200B, 747-300, 747SR, and 
747SP series airplanes of U.S. registry will be affected by the 
required actions. It will take about 7 work hours per airplane to do 
the required actions, at an average labor rate of $65 per work hour. 
Required parts will cost about $143 per airplane. Based on these 
figures, the estimated cost of the AD for these U.S. operators is 
$13,156, or $598 per airplane.
    About 44 Model 747-400 and 747-400D series airplanes of U.S. 
registry will be affected by the required actions. It will take about 2 
work hours per airplane to do the required actions, at an average labor 
rate of $65 per work hour. Required parts will cost about $4,934 per 
airplane. Based on these figures, the estimated cost of the AD for 
these U.S. operators is $222,816, or $5,064 per airplane.

    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. See the ADDRESSES section for a location to 
examine the regulatory evaluation.

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 FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2005-10-19 Boeing: Amendment 39-14096. Docket No. FAA-2004-19532; 
Directorate Identifier 2004-NM-87-AD.

Effective Date

    (a) This AD becomes effective June 23, 2005.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to certain Boeing Model 747-100, 747-100B, 
747-200B, 747-300, 747SR, and 747SP series airplanes, as identified 
in Boeing Alert Service Bulletin 747-25A3287, Revision 2, dated 
September 4, 2003; and Model 747-400 and 747-400D series airplanes, 
as identified in Boeing Service Bulletin 747-25A3187, Revision 2, 
dated January 27, 2000; certificated in any category.

Unsafe Condition

    (d) This AD was prompted by reports of injuries to catering 
personnel and flight attendants who were loading or unloading galley 
carts on one deck when, due to a disabled or malfunctioning safety 
interlock door switch, the galley cart lift unexpectedly moved when 
it was activated from the control panel on the other deck. We are 
issuing this AD to ensure that the galley cart lift can be sent only 
from the deck on which it is in use, which will prevent unexpected 
movement of the cart lift that could result in possible injury to 
catering personnel or flight attendants.

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.

this AD, as applicable.

main and upper deck control panels for the galley cart lift with new 
or modified control panels by doing all the actions specified in 
Boeing Service Bulletin 747-25A3187, Revision 2, dated January 27, 
2000.
    (2) For Model 747-100, 747-100B, 747-200B, 747-300, 747SR, and 
747SP series airplanes: Modify the main and upper deck control 
panels and related cable assemblies for the galley cart lift by 
doing all the actions specified in Boeing Alert Service Bulletin 
747-25A3287, Revision 2, dated September 4, 2003.

accordance with Boeing Alert Service Bulletin 747-25A3287, dated 
October 25, 2001, or Revision 1, dated April 25, 2002; or in 
accordance with Boeing Service Bulletin 747-25A3187, dated April 29, 
1999, or Revision 1, dated September 23, 1999; are considered 
acceptable for compliance with the corresponding actions specified 
in paragraph (f) of this AD.
