ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747–200C and 747–200F series airplanes. This AD requires onetime inspections for cracks and material loss in the fuselage skin above the stringer (STR) 23 lap splice, between Body Station (BS) 282 and BS 298, and repair if necessary. This AD is prompted by a report of a crack above the STR 23 lap splice on one airplane. We are issuing this AD to detect and correct cracks or material loss in the fuselage skin, and consequent reduced structural integrity of the skin panel, which could result in rapid depressurization of the airplane. This AD becomes effective August 26, 2005. The incorporation by reference of a certain publication listed in the AD is approved by the Director of the Federal Register as of August 26, 2005. ADDRESSES: For service information identified in this AD, contact Boeing Commercial Airplanes, P.O. Box 3707, Seattle, Washington 98124–2207. Docket: The AD docket contains the proposed AD, comments, and any final disposition.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 with an AD for certain Boeing Model 747– 200C and 747–200F series airplanes. That action, published in the Federal Register on March 23, 2005 (70 FR 14587), proposed to require one-time inspections for cracks and material loss in the fuselage skin above the stringer (STR) 23 lap splice, between Body Station (BS) 282 and BS 298, and repair if necessary. Comments We provided the public the opportunity to participate in the development of this AD. We have considered the comment that has been submitted on the proposed AD. Request To Re-Evaluate Need for the Proposed Rule One commenter, an airplane operator, notes that it has previously inspected the fuselage skin thickness at the affected area on two of its ten production freighter airplanes. The inspections, which the commenter points out were conducted at the manufacturer’s recommendation, showed skin thickness of 0.060 inch or greater on both airplanes. The commenter asserts that our justification for adopting the proposed AD should cite the results of its inspections and any similar inspections conducted at the manufacturer’s request by other operators; and notes that Boeing Special Attention Service Bulletin 747–53– 2493, dated July 3, 2003, cites only one instance of the problem that is prompting the proposed AD. The commenter acknowledges the significance of fuselage skin cracking, and recognizes the fact that the maintenance program for the affected Model 747–200C and 747–200F series airplanes includes external visual inspections of the affected area at regular intervals. However, the commenter questions our justification for adopting the proposed AD. E:\FR\FM\22JYR1.SGM 22JYR1 42270 Federal Register / Vol. 70, No. 140 / Friday, July 22, 2005 / Rules and Regulations We infer that the commenter is questioning whether the proposed AD addresses a safety issue and, if not, we further infer that the commenter requests that we withdraw the proposed AD. We disagree. Although the commenter had no findings of cracking or blended skin on two of its airplanes, other respondents to the manufacturer’s survey did report airplanes with skin thickness that was below the minimum. In addition, there are many airplanes affected by this proposed AD that have not yet been inspected. However, we do agree that we should clarify the unsafe condition. Investigation of the crack report that prompted this proposed AD showed that the skin at the crack location was not the correct thickness. Boeing audited its manufacturing processes and discovered that assembly techniques of the skin panels during final assembly at the factory were the likely cause of the thin skin at the affected sections. It is very likely that the same condition may exist on other airplanes that were manufactured using the same techniques. Furthermore, the finding that precipitated this proposed AD was a three-inch crack in the upper row of the lap splice just above the upper row. Cracking in this area is critical due to its proximity to the upper row and possible interaction of cracks between the blended area and the upper row. Therefore, the crack finding, coupled with the likelihood that the thin skin condition exists on other airplanes, provides sufficient justification for adopting the proposed AD to detect and correct cracks or material loss in the fuselage skin. We have not changed the final rule in this regard. Conclusion We have carefully reviewed the available data, including the comment that was submitted, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance There are about 77 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. ESTIMATED COSTS Action Work hours Average labor rate per hour Parts Cost per airplane Number of U.S.registered airplanes Fleet cost Inspections ........................................ 6 $65 None ................................................. $390 20 $7,800 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 15:02 Jul 21, 2005 Jkt 205001 (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.

BILLING CODE 4910–13–P Food and Drug Administration, HHS. 42271 Sfmt 4700 In a notice published in the Federal Register of June 22, 1998 (63 FR 33934), FDA announced that a color additive petition (CAP 8C0257) had been filed by EM Industries, Inc., 7 Skyline Dr., Hawthorne, NY 10532 (now EMD Industries, Inc.). The petition proposed to amend the color additive regulations to provide for the safe use of synthetic iron oxide to color ingested drugs at levels higher than the current limit and to provide for the safe use of mica to color ingested drugs. At the time of the filing of the petition, FDA considered the pigments that are the subjects of this petition to be color additive mixtures of synthetic iron oxide, mica, and titanium dioxide. FDA did not include titanium dioxide in the filing notice, because that color additive was already listed for use in ingested drugs. During its subsequent review of the petition, the agency determined that these pigments are composite pigments, not color additive mixtures. Therefore, the agency published an amended filing notice in the Federal Register of June 29, 1999 (64 FR 34816), to indicate that the petition proposed to amend the color additive regulations to provide for the safe use of composite pigments prepared from synthetic iron oxide, mica, and titanium dioxide to color ingested drugs. The petitioner is seeking approval for a maximum use level of the resulting pigments of up to 3 percent by weight in the finished drug product, and a maximum iron oxide content no greater than 55 percent in those pigments containing iron oxide. II. Manufacturing and Nomenclature The subject color additives are manufactured by preparing a suspension of mica platelets, adding a solution of soluble salts of titanium, of iron, or of both, and a base to precipitate titanium hydroxide, iron hydroxide, or both onto the mica platelets. These particles are then heated (calcined) at temperatures up to 900 °C. During the calcination, titanium hydroxide and E:\FR\FM\22JYR1.SGM 22JYR1

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 747-200C and 747-200F series airplanes. This AD 
requires one-time inspections for cracks and material loss in the 
fuselage skin above the stringer (STR) 23 lap splice, between Body 
Station (BS) 282 and BS 298, and repair if necessary. This AD is 
prompted by a report of a crack above the STR 23 lap splice on one 
airplane. We are issuing this AD to detect and correct cracks or 
material loss in the fuselage skin, and consequent reduced structural 
integrity of the skin panel, which could result in rapid 
depressurization of the airplane.

DATES: This AD becomes effective August 26, 2005.
    The incorporation by reference of a certain publication listed in 
the AD is approved by the Director of the Federal Register as of August 
26, 2005.

ADDRESSES: For service information identified in this AD, contact 
Boeing Commercial Airplanes, P.O. Box 3707, Seattle, Washington 98124-
2207.
    Docket: The AD docket contains the proposed AD, comments, and any 
final disposition. You can examine the AD docket on the Internet at 
https://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-

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR part 39 
with an AD for certain Boeing Model 747-200C and 747-200F series 
airplanes. That action, published in the Federal Register on March 23, 
2005 (70 FR 14587), proposed to require one-time inspections for cracks 
and material loss in the fuselage skin above the stringer (STR) 23 lap 
splice, between Body Station (BS) 282 and BS 298, and repair if 
necessary.

Comments

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

Request To Re-Evaluate Need for the Proposed Rule

    One commenter, an airplane operator, notes that it has previously 
inspected the fuselage skin thickness at the affected area on two of 
its ten production freighter airplanes. The inspections, which the 
commenter points out were conducted at the manufacturer's 
recommendation, showed skin thickness of 0.060 inch or greater on both 
airplanes. The commenter asserts that our justification for adopting 
the proposed AD should cite the results of its inspections and any 
similar inspections conducted at the manufacturer's request by other 
operators; and notes that Boeing Special Attention Service Bulletin 
747-53-2493, dated July 3, 2003, cites only one instance of the problem 
that is prompting the proposed AD. The commenter acknowledges the 
significance of fuselage skin cracking, and recognizes the fact that 
the maintenance program for the affected Model 747-200C and 747-200F 
series airplanes includes external visual inspections of the affected 
area at regular intervals. However, the commenter questions our 
justification for adopting the proposed AD.

[[Page 42270]]

    We infer that the commenter is questioning whether the proposed AD 
addresses a safety issue and, if not, we further infer that the 
commenter requests that we withdraw the proposed AD. We disagree. 
Although the commenter had no findings of cracking or blended skin on 
two of its airplanes, other respondents to the manufacturer's survey 
did report airplanes with skin thickness that was below the minimum. In 
addition, there are many airplanes affected by this proposed AD that 
have not yet been inspected.
    However, we do agree that we should clarify the unsafe condition. 
Investigation of the crack report that prompted this proposed AD showed 
that the skin at the crack location was not the correct thickness. 
Boeing audited its manufacturing processes and discovered that assembly 
techniques of the skin panels during final assembly at the factory were 
the likely cause of the thin skin at the affected sections. It is very 
likely that the same condition may exist on other airplanes that were 
manufactured using the same techniques. Furthermore, the finding that 
precipitated this proposed AD was a three-inch crack in the upper row 
of the lap splice just above the upper row. Cracking in this area is 
critical due to its proximity to the upper row and possible interaction 
of cracks between the blended area and the upper row. Therefore, the 
crack finding, coupled with the likelihood that the thin skin condition 
exists on other airplanes, provides sufficient justification for 
adopting the proposed AD to detect and correct cracks or material loss 
in the fuselage skin.
    We have not changed the final rule in this regard.

Conclusion

    We have carefully reviewed the available data, including the 
comment that was submitted, and determined that air safety and the 
public interest require adopting the AD as proposed.

Costs of Compliance

    There are about 77 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.

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

2005-15-06 Boeing: Amendment 39-14195. Docket No. FAA-2005-20690; 
Directorate Identifier 2003-NM-230-AD.

Effective Date

    (a) This AD becomes effective August 26, 2005.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Boeing Model 747-200C and 747-200F series 
airplanes, equipped with a nose cargo door, certificated in any 
category; as identified in paragraph 1.A.1 of Boeing Special 
Attention Service Bulletin 747-53-2493, dated July 3, 2003.

Unsafe Condition

    (d) This AD was prompted by a report of a crack above the 
stringer (STR) 23 lap splice on a Model 747-200F series airplane. We 
are issuing this AD to detect and correct cracks or material loss in 
the fuselage skin, and consequent reduced structural integrity of 
the skin panel, which could result in rapid depressurization of the 
airplane.

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.

Inspections and Repair

    (f) Before the accumulation of 15,000 total flight cycles, or 
within 1,200 flight cycles after the effective date of this AD, 
whichever occurs later: Do a detailed inspection for cracking, and a 
low frequency eddy current inspection for material loss, in the 
fuselage skin. Repair any crack or material loss prior

to further flight. Do all actions in accordance with the 
Accomplishment Instructions of Boeing Special Attention Service 
Bulletin 747-53-2493, dated July 3, 2003.

    Note 1: For the purposes of this AD, a detailed inspection is: 
``An intensive examination of a specific item, installation, or 
assembly to detect damage, failure, or irregularity. Available 
lighting is normally supplemented with a direct source of good 
lighting at an intensity deemed appropriate. Inspection aids such as 
mirror, magnifying lenses, etc., may be necessary. Surface cleaning 
and elaborate procedures may be required.''

Alternative Methods of Compliance (AMOCs)

    (g)(1) The Manager, Seattle Aircraft Certification Office (ACO), 
FAA, has the authority to approve AMOCs for this AD, if requested in 
accordance with the procedures found in 14 CFR 39.19.
    (2) An AMOC that provides an acceptable level of safety may be 
used for any repair required by this AD, if it is approved by an 
Authorized Representative for the Boeing Delegation Option 
Authorization Organization who has been authorized by the Manager, 
Seattle ACO, to make those findings. For a repair method to be 
approved, the repair must meet the certification basis of the 
airplane, and the approval must specifically refer to this AD.

Material Incorporated by Reference

    (h) You must use Boeing Special Attention Service Bulletin 747-
53-2493, dated July 3, 2003, to perform the actions that are 
required by this AD, unless the AD specifies otherwise. The Director
