ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747–200B, 747–300, 747– 400, and 747–400D series airplanes. This AD requires 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 AD results from a report indicating 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. DATES: This AD becomes effective September 6, 2005. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of September 6, 2005.

SUPPLEMENTARY INFORMATION: Examining the Docket You may examine the AD docket 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. This docket number is FAA–2005– 20661; the directorate identifier for this docket is 2004–NM–261–AD. Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain Boeing Model 747– 200B, 747–300, 747–400, and 747–400D series airplanes. That NPRM was published in the Federal Register on March 22, 2005 (70 FR 14428). That NPRM proposed to require modifying the lateral shear beam for the Door 5 crew rest and, for certain airplanes, replacing the Zone E tie rods and modifying the Zone E stowbin ladder. 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. Support for the Proposed AD One commenter, the manufacturer, supports the proposed AD. Request To Reduce Compliance Time One commenter requests that the compliance time of 5 years to accomplish the actions specified in the proposed AD be shortened substantially. The commenter states that a 5-year compliance time is too long given that the affected lateral shear beam does not meet the 9G forward loading requirement. We do not agree. The lateral shear beam has been substantiated to be structurally capable of carrying all flight, gust, and ground loads that may be encountered during normal operations by the subject Model 747– 200B, 747–300, 747–400, and 747–400D series airplanes. The 9G forward loading requirement of section 25.561 (‘‘General’’) of the Federal Aviation Regulations (14 CFR 25.561) is an emergency landing load condition only E:\FR\FM\02AUR1.SGM 02AUR1 Federal Register / Vol. 70, No. 147 / Tuesday, August 2, 2005 / Rules and Regulations and there is a very low probability that such loads will be encountered. In developing the compliance time to adequately address the subject unsafe condition, we considered the degree of urgency associated with 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 found a compliance time of 60 months for completing the proposed modification to be warranted, in that it allows operators to schedule the modification during a routine heavy check and represents an appropriate interval of time for affected airplanes to continue to operate without compromising safety. This compliance time was coordinated with the manufacturer. We have not revised the final rule in this regard. Request To Clarify Applicability One commenter requests that the applicability be clarified. The commenter suggests adding wording to exclude freighters and special freighters. The commenter notes that the Door 5 crew rest is only applicable to passenger airplanes. We agree that the proposed AD is applicable only to passenger models equipped with a Door 5 crew rest. The applicability of the proposed AD includes Model 747–200B, 747–300, 747–400, and 747–400D series airplanes as identified in specific Boeing service bulletins. All of the airplanes identified in these service bulletins are passenger models equipped with a Door 5 crew rest; none of the airplanes identified in the service bulletins are freighters or 44277 special freighters. Therefore, it is not necessary to clarify the applicability to exclude freighters and special freighters. We have not revised 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 as proposed. Costs of Compliance There are about 424 airplanes of the affected design in the worldwide fleet. This AD will affect about 65 airplanes of U.S. registry. The following table provides the estimated costs for U.S. operators to comply with this AD. ESTIMATED COSTS Modification .......................................... 86–207 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: VerDate jul<14>2003 15:06 Aug 01, 2005 Average labor rate per hour Work hours Action Jkt 205001 $65 Cost per airplane Parts Number of U.S.registered airplanes $12,685–$51,225 65 $7,095–$37,770 (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.

Box 25082 Oklahoma City, OK. 73125) telephone: (405) 954–4164. SUPPLEMENTARY INFORMATION: This amendment to part 95 of the Federal Aviation Regulations (14 CFR part 95) amends, suspends, or revokes IFR altitudes governing the operation of all aircraft in flight over a specified route or any portion of that route, as well as the changeover points (COPs) for Federal airways, jet routes, or direct routes as prescribed in part 95. The Rule The specified IFR altitudes, when used in conjunction with the prescribed changeover points for those routes, ensure navigation aid coverage that is adequate for safe flight operations and free of frequency interference. The reasons and circumstances that create the need for this amendment involve matters of flight safety and operational efficiency in the National Airspace System, are related to published aeronautical charts that are essential to PO 00000 Frm 00060 Fmt 4700 Sfmt 4700 the user, and provide for the safe and efficient use of the navigable airspace. In addition, those various reasons or circumstances require making this amendment effective before the next scheduled charting and publication date of the flight information to assure its timely availability to the user. The effective date of this amendment reflects those considerations. In view of the close and immediate relationship between these regulatory changes and safety in air commerce, I find that notice and public procedure before adopting this amendment are impracticable and contrary to the public interest and that good cause exists for making the amendment effective in less than 30 days. Conclusion The FAA has determined that this regulation only involves an established body of technical regulations for which frequent and routine amendments are necessary to keep them operationally current. It, therefore—(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) does not warrant preparation of a regulatory evaluation as the anticipated impact is so minimal. For the same reason, the FAA certifies that this amendment will not have a significant economic impact on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

Airworthiness Directives; Boeing Model 747-200B, 747-300, 747-
400, and 747-400D Series Airplanes

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 747-200B, 747-300, 747-400, and 747-400D series 
airplanes. This AD requires 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 AD results from a report 
indicating 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.

DATES: This AD becomes effective September 6, 2005.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of September 6, 
2005.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the AD docket 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. This 
docket number is FAA-2005-20661; the directorate identifier for this 
docket is 2004-NM-261-AD.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain Boeing Model 
747-200B, 747-300, 747-400, and 747-400D series airplanes. That NPRM 
was published in the Federal Register on March 22, 2005 (70 FR 14428). 
That NPRM proposed to require modifying the lateral shear beam for the 
Door 5 crew rest and, for certain airplanes, replacing the Zone E tie 
rods and modifying the Zone E stowbin ladder.

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.

Support for the Proposed AD

    One commenter, the manufacturer, supports the proposed AD.

Request To Reduce Compliance Time

    One commenter requests that the compliance time of 5 years to 
accomplish the actions specified in the proposed AD be shortened 
substantially. The commenter states that a 5-year compliance time is 
too long given that the affected lateral shear beam does not meet the 
9G forward loading requirement.
    We do not agree. The lateral shear beam has been substantiated to 
be structurally capable of carrying all flight, gust, and ground loads 
that may be encountered during normal operations by the subject Model 
747-200B, 747-300, 747-400, and 747-400D series airplanes. The 9G 
forward loading requirement of section 25.561 (``General'') of the 
Federal Aviation Regulations (14 CFR 25.561) is an emergency landing 
load condition only

[[Page 44277]]

and there is a very low probability that such loads will be 
encountered.
    In developing the compliance time to adequately address the subject 
unsafe condition, we considered the degree of urgency associated with 
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 found a compliance time of 60 months for completing 
the proposed modification to be warranted, in that it allows operators 
to schedule the modification during a routine heavy check and 
represents an appropriate interval of time for affected airplanes to 
continue to operate without compromising safety. This compliance time 
was coordinated with the manufacturer. We have not revised the final 
rule in this regard.

Request To Clarify Applicability

    One commenter requests that the applicability be clarified. The 
commenter suggests adding wording to exclude freighters and special 
freighters. The commenter notes that the Door 5 crew rest is only 
applicable to passenger airplanes.
    We agree that the proposed AD is applicable only to passenger 
models equipped with a Door 5 crew rest.
    The applicability of the proposed AD includes Model 747-200B, 747-
300, 747-400, and 747-400D series airplanes as identified in specific 
Boeing service bulletins. All of the airplanes identified in these 
service bulletins are passenger models equipped with a Door 5 crew 
rest; none of the airplanes identified in the service bulletins are 
freighters or special freighters. Therefore, it is not necessary to 
clarify the applicability to exclude freighters and special freighters. 
We have not revised 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 as proposed.

Costs of Compliance

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

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

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

2005-16-01 Boeing: Amendment 39-14206. Docket No. FAA-2005-20661; 
Directorate Identifier 2004-NM-261-AD.

Effective Date

    (a) This AD becomes effective September 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 
been done.
    (3) Model 747-400 and 747-400D series airplanes identified in 
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.
