Download as PDF 14428 Federal Register / Vol. 70, No. 54 / Tuesday, March 22, 2005 / Proposed Rules For the reasons stated in the preamble, DHS proposes to amend Chapter I of Title 6, Code of Federal Regulations, as follows: PART 5—DISCLOSURE OF RECORDS AND INFORMATION 1. The authority citation for Part 5 continues to read as follows: Authority: Pub. L. 107–296, 116 Stat. 2135, 6 U.S.C. 101 et seq.; 5 U.S.C. 301. Subpart A also issued under 5 U.S.C. 552. Subpart B also issued under 5 U.S.C. 552a. 2. Add Appendix C to Part 5 the following: Appendix C to Part 5—DHS Systems of Records Exempt From the Privacy Act This Appendix implements provisions of the Privacy Act of 1974 that permit the Department of Homeland Security (DHS) to exempt its systems of records from provisions of the Act. Portions of the following DHS systems of records are exempt from certain provisions of the Privacy Act pursuant to 5 U.S.C. 552(j) and (k): 1. DHS/ICE 001, the Student and Exchange Visitor Information System, which allows DHS to collect and maintain information on nonimmigrant students and exchange visitors, and the schools and exchange program sponsors that host them in the United States. The system permits DHS to monitor compliance by these individuals with the terms of their admission into the United States. Pursuant to exemptions (j)(2), (k)(1), (k)(2) and (k)(5) of the Privacy Act, portions of this system are exempt from 5 U.S.C. 552a(c)(3); (d); (e)(1); (e)(4)(G), (H) and (I). Exemptions from the particular subsections are justified, on a case by case basis to be determined at the time a request is made, for the following reasons: (a) From subsection (c)(3) (Accounting for Disclosures) because release of the accounting of disclosures could alert the subject of an investigation, of an actual or potential criminal, civil, or regulatory violation to the existence of the investigation and reveal investigative interest on the part of DHS as well as the recipient agency. Disclosure of the accounting would therefore present a serious impediment to law enforcement efforts and/or efforts to preserve national security. Disclosure of the accounting would also permit the individual who is the subject of a record to impede the investigation and avoid detection or apprehension, which undermines the entire system. (b) From subsection (d) (Access to Records) because access to the records contained in this system of records could inform the subject of an investigation, of an actual or potential criminal, civil, or regulatory violation to the existence of the investigation and reveal investigative interest on the part of DHS or another agency. Access to the records could permit the individual who is the subject of a record to impede the investigation and avoid detection or apprehension. Amendment of the records VerDate jul<14>2003 15:25 Mar 21, 2005 Jkt 205001 could interfere with ongoing investigations and law enforcement activities and impose an impossible administrative burden by requiring investigations to be continuously reinvestigated. In addition, permitting access and amendment to such information also could disclose security-sensitive information that could be detrimental to homeland security. (c) From subsection (e)(1) (Relevancy and Necessity of Information) because in the course of investigations into potential violations of federal law, the accuracy of information obtained or introduced occasionally may be unclear or the information may not be strictly relevant or necessary to a specific investigation. In the interests of effective enforcement of federal laws, it is appropriate to retain all information that may aid in establishing patterns of unlawful activity. (d) From subsections (e)(4)(G), (H) and (I) (Agency Requirements), and (f) (Agency Rules), because portions of this system are exempt from the access provisions of subsection (d).

Comments will be available in the AD docket shortly after the DMS receives them. Discussion We have received a report indicating that the lateral shear beam for the Door 5 crew rest does not meet the 9G forward loading requirement on certain Boeing Model 747 series airplanes. This condition, if not corrected, could result in the failure of the structural support for the Door 5 crew rest and Zone E stowbins, and could result in the crew rest or stowbins falling during an emergency and consequent injury to crew and passengers. Relevant Service Information We have reviewed Boeing Special Attention Service Bulletin 747–53– 2497, dated November 4, 2004 (for Boeing Model 747–200B and –300 series airplanes), which describes procedures for modifying the lateral shear beam for the Door 5 crew rest. The modification includes replacing the web with a new thicker web and installing additional stiffeners. We have also reviewed Boeing Special Attention Service Bulletin 747–53– 2481, dated October 24, 2002 (for Boeing Model 747–400 and –400D series airplanes), which describes procedures for modifying the lateral shear beam for the Door 5 crew rest and replacing Zone E tie rods with new tie rods and modifying the Zone E stowbin ladder by installing new intercostals. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. FAA’s Determination and Requirements of the Proposed AD We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other airplanes of this same type design. Therefore, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously, except as discussed under 14429 ‘‘Differences Between the Proposed AD and the Service Bulletins.’’ Differences Between the Proposed AD and the Service Bulletins Boeing Special Attention Service Bulletin 747–53–2497 recommends accomplishing the modification ‘‘at the earliest opportunity when manpower, materials and facilities are available,’’ and Boeing Special Attention Service Bulletin 747–53–2481 recommends accomplishing the modification ‘‘within 3 years of the release date on the service bulletin.’’ However, this proposed AD specifies accomplishing the modification within 60 months after the effective date of the AD. In developing an appropriate compliance time for this AD, we considered the degree of urgency associated with addressing the subject unsafe condition, the average utilization of the affected fleet, and the time necessary to perform the modification. In light of all of these factors, we find a compliance time of 60 months for completing the proposed modification to be warranted, in that it represents an appropriate interval of time for affected airplanes to continue to operate without compromising safety. We have coordinated this compliance time with the manufacturer. Costs of Compliance There are about 424 airplanes of the affected design in the worldwide fleet. This proposed AD would affect about 65 airplanes of U.S. registry. The following table provides the estimated costs for U.S. operators to comply with this proposed AD. ESTIMATED COSTS Action Work hours Average labor rate per hour Parts Cost per airplane Number of U.S.-registered airplanes Fleet cost Modification .................................. 86–207 $65 $7,095–$37,770 $12,685–$51,225 65 $824,525–$3,329,625 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 VerDate jul<14>2003 15:25 Mar 21, 2005 Jkt 205001 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 PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 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. E:\FR\FM\22MRP1.SGM 22MRP1 14430 Federal Register / Vol. 70, No. 54 / Tuesday, March 22, 2005 / Proposed Rules We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD.

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Boeing Model 747-200B, 747-300, 747-400, and 747-400D
series airplanes. This proposed AD would require modifying the lateral
shear beam for the Door 5 crew rest and, for certain airplanes,
replacing Zone E tie rods and modifying the Zone E stowbin ladder. This
proposed AD is prompted by a report indicating that the lateral shear
beam for the Door 5 crew rest does not meet the 9G forward loading
requirement. We are proposing this AD to prevent the structural support
for the Door 5 crew rest and Zone E stowbins from failing during an
emergency, which could result in the crew rest or stowbins falling and
consequent injury to crew and passengers.

Discussion

We have received a report indicating that the lateral shear beam
for the Door 5 crew rest does not meet the 9G forward loading
requirement on certain Boeing Model 747 series airplanes. This
condition, if not corrected, could result in the failure of the
structural support for the Door 5 crew rest and Zone E stowbins, and
could result in the crew rest or stowbins falling during an emergency
and consequent injury to crew and passengers.

Relevant Service Information

We have reviewed Boeing Special Attention Service Bulletin 747-53-
2497, dated November 4, 2004 (for Boeing Model 747-200B and -300 series
airplanes), which describes procedures for modifying the lateral shear
beam for the Door 5 crew rest. The modification includes replacing the
web with a new thicker web and installing additional stiffeners.
We have also reviewed Boeing Special Attention Service Bulletin
747-53-2481, dated October 24, 2002 (for Boeing Model 747-400 and -400D
series airplanes), which describes procedures for modifying the lateral
shear beam for the Door 5 crew rest and replacing Zone E tie rods with
new tie rods and modifying the Zone E stowbin ladder by installing new
intercostals.
Accomplishing the actions specified in the service information is
intended to adequately address the unsafe condition.

FAA's Determination and Requirements of the Proposed AD

We have evaluated all pertinent information and identified an
unsafe condition that is likely to exist or develop on other airplanes
of this same type design. Therefore, we are proposing this AD, which
would require accomplishing the actions specified in the service
information described previously, except as discussed under
``Differences Between the Proposed AD and the Service Bulletins.''

Differences Between the Proposed AD and the Service Bulletins

Boeing Special Attention Service Bulletin 747-53-2497 recommends
accomplishing the modification ``at the earliest opportunity when
manpower, materials and facilities are available,'' and Boeing Special
Attention Service Bulletin 747-53-2481 recommends accomplishing the
modification ``within 3 years of the release date on the service
bulletin.'' However, this proposed AD specifies accomplishing the
modification within 60 months after the effective date of the AD. In
developing an appropriate compliance time for this AD, we considered
the degree of urgency associated with addressing the subject unsafe
condition, the average utilization of the affected fleet, and the time
necessary to perform the modification. In light of all of these
factors, we find a compliance time of 60 months for completing the
proposed modification to be warranted, in that it represents an
appropriate interval of time for affected airplanes to continue to
operate without compromising safety. We have coordinated this
compliance time with the manufacturer.

Costs of Compliance

There are about 424 airplanes of the affected design in the
worldwide fleet. This proposed AD would affect about 65 airplanes of
U.S. registry. The following table provides the estimated costs for
U.S. operators to comply with this proposed AD.

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

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Safety.

The Proposed Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

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]

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

Boeing: Docket No. FAA-2005-20661; Directorate Identifier 2004-NM-
261-AD.

Comments Due Date

(a) The Federal Aviation Administration (FAA) must receive
comments on this AD action by May 6, 2005.

Affected ADs

(b) None.

Applicability

(c) This AD applies to the Boeing airplanes, certificated in any
category, specified in paragraphs (c)(1), (c)(2), and (c)(3) of this
AD.
(1) Model 747-200B and 747-300 series airplanes identified in
Boeing Special Attention Service Bulletin 747-53-2497, dated
November 4, 2004.
(2) Model 747-200B and 747-300 series airplanes on which Boeing
Service Bulletins 747-25-2716, 747-25-2724, and 747-25-2784 have

Boeing Special Attention Service Bulletin 747-53-2481, dated October
24, 2002.

Unsafe Condition

(d) This AD was prompted by a report that the lateral shear beam
for the Door 5 crew rest does not meet the 9G forward loading
requirement. We are issuing this AD to prevent the structural
support for the Door 5 crew rest and Zone E stowbins from failing,
which could result in the crew rest or stowbins falling during an
emergency and consequent injury to crew and passengers.

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.

Model 747-200B and 747-300: Modification

(f) Within 60 months after the effective date of this AD, modify
the lateral shear beam for the Door 5 crew rest by accomplishing all
of the actions specified in the Accomplishment Instructions of
Boeing Special Attention Service Bulletin 747-53-2497, dated
November 4, 2004.

Model 747-400 and 747-400D: Modification and Replacement

tie rods, and modify the Zone E stowbin ladder, by accomplishing all
of the actions specified in the Accomplishment Instructions of
Boeing Special Attention Service Bulletin 747-53-2481, dated October
24, 2002.

Alternative Methods of Compliance (AMOCs)
