AGENCY: Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
SUMMARY: The FAA is revising an
existing airworthiness directive (AD)
that applies to certain Boeing Model
747–100, 747–100B, 747–100B SUD,
747–200B, 747–300, 747–400, 747–
400D, and 747SR series airplanes. That
AD currently requires repetitive
inspections to detect cracking of certain
lower lobe fuselage frames, and repair if
necessary. This new AD specifies
appropriate service information for
certain corrective actions. This AD
results from reports indicating that
fatigue cracks were found in lower lobe
frames on the left side of the fuselage.
We are issuing this AD to detect and
correct fatigue cracking of certain lower
lobe fuselage frames, which could lead
to fatigue cracks in the fuselage skin,
and consequent rapid decompression of
the airplane.
DATES: The effective date of this AD is
June 7, 2006.
On June 7, 2006 (71 FR 25926, May
3, 2006), the Director of the Federal
Register approved the incorporation by
reference of Boeing Alert Service
Bulletin 747–53A2408, Revision 1,
dated April 4, 2002.
On May 5, 1999 (64 FR 15298, March
31, 1999), the Director of the Federal
Register approved the incorporation by
reference of Boeing Alert Service
Bulletin 747–53A2408, dated April 25,
1996.

Discussion
The FAA proposed to amend part 39
of the Federal Aviation Regulations (14
CFR part 39) with an airworthiness
directive (AD) to revise AD 2006–09–06,
amendment 39–14576 (71 FR 25926,
May 3, 2006). The existing AD applies
to certain Boeing Model 747–100, 747–
100B, 747–100B SUD, 747–200B, 747–
300, 747–400, 747–400D, and 747SR
series airplanes. The proposed AD was
published in the Federal Register on
July 13, 2006 (71 FR 39600) to require
repetitive inspections to detect cracking
of certain lower lobe fuselage frames,
and repair if necessary, and to specify
appropriate service information for
certain corrective actions.
Comments
We provided the public the
opportunity to participate in the
development of this AD. We have
considered the comments received.
Support for the Proposed AD
Boeing supports the proposed AD.
Request To Change Incorporation of
Certain Information
The Modification and Replacement
Parts Association (MARPA) states that,
typically, airworthiness directives are
based on service information originating
with the type certificate holder or its
suppliers. MARPA adds that
manufacturer service documents are
E:\FR\FM\07DER1.SGM
07DER1
sroberts on PROD1PC70 with RULES
70858
Federal Register / Vol. 71, No. 235 / Thursday, December 7, 2006 / Rules and Regulations
privately authored instruments
generally having copyright protection
against duplication and distribution.
MARPA notes that when a service
document is incorporated by reference
into a public document, such as an
airworthiness directive, it loses its
private, protected status and becomes a
public document. MARPA adds that if
a service document is used as a
mandatory element of compliance, it
should not simply be referenced, but
should be incorporated into the
regulatory document; by definition,
public laws must be public, which
means they cannot rely upon private
writings. MARPA is concerned that the
failure to incorporate essential service
information could result in a court
decision invalidating the AD.
MARPA adds that incorporated by
reference service documents should be
made available to the public by
publication in the Docket Management
System (DMS), keyed to the action that
incorporates them. MARPA notes that
the stated purpose of the incorporation
by reference method is brevity, to keep
from expanding the Federal Register
needlessly by publishing documents
already in the hands of the affected
individuals; traditionally, ‘‘affected
individuals’’ means aircraft owners and
operators, who are generally provided
service information by the
manufacturer. MARPA adds that a new
class of affected individuals has
emerged, since the majority of aircraft
maintenance is now performed by
specialty shops instead of aircraft
owners and operators. MARPA notes
that this new class includes
maintenance and repair organizations,
component servicing and repair shops,
parts purveyors and distributors, and
organizations manufacturing or
servicing alternatively certified parts
under 14 CFR 21.303 (parts
manufacturer approval (PMA)). MARPA
adds that the concept of brevity is now
nearly archaic as documents exist more
frequently in electronic format than on
paper. Therefore, MARPA asks that the
service documents deemed essential to
the accomplishment of the NPRM be
incorporated by reference into the
regulatory instrument, and published in
the DMS.
We do not agree that documents
should be incorporated by reference
during the NPRM phase of rulemaking.
The Office of the Federal Register (OFR)
requires that documents that are
necessary to accomplish the
requirements of the AD be incorporated
by reference during the final rule phase
of rulemaking. This final rule
incorporates by reference the document
necessary for the accomplishment of the
VerDate Aug<31>2005
20:43 Dec 06, 2006
Jkt 211001
requirements mandated by this AD.
Further, we point out that while
documents that are incorporated by
reference do become public information,
they do not lose their copyright
protection. For that reason, we advise
the public to contact the manufacturer
to obtain copies of the referenced
service information.
Additionally, we do not publish
service documents in DMS. We are
currently reviewing our practice of
publishing proprietary service
information. Once we have thoroughly
examined all aspects of this issue, and
have made a final determination, we
will consider whether our current
practice needs to be revised. However,
we consider that to delay this AD action
for that reason would be inappropriate,
since we have determined that an
unsafe condition exists and that the
requirements in this AD must be
accomplished to ensure continued
safety. Therefore, we have not changed
the AD in this regard.
Explanation of Change to Heading
We have revised the heading,
‘‘RESTATEMENT OF THE
REQUIREMENTS OF AD 99–07–12,
WITH ADDITIONAL INFORMATION
FOR GROUP 2 AIRPLANES,’’ to state,
‘‘* * * WITH COMPLIANCE TIMES
FOR GROUP 2 AIRPLANES.’’ This
change provides more information about
the new requirements of this AD.
Conclusion
We have carefully reviewed the
available data, including the comments
received, and determined that air safety
and the public interest require adopting
the AD with the change described
previously. We have determined that
this change will neither increase the
economic burden on any operator nor
increase the scope of the AD.
Costs of Compliance
There are about 681 airplanes of the
affected design in the worldwide fleet.
This AD affects about 99 airplanes of
U.S. registry. The new requirements of
this AD add no additional economic
burden. The current costs for this AD
are repeated for the convenience of
affected operators, as follows:
The actions in this AD take about 2
work hours per airplane, at an average
labor rate of $80 per work hour. Based
on these figures, the estimated cost of
both the retained and new actions for
U.S. operators is $15,840, or $160 per
airplane, per inspection cycle.
Authority for This Rulemaking
Title 49 of the United States Code
specifies the FAA’s authority to issue
PO 00000
Frm 00004
Fmt 4700
Sfmt 4700
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.

Discussion
The FAA proposed to amend part 39 of the Federal Aviation
Regulations (14 CFR part 39) with an airworthiness directive (AD) to
revise AD 2006-09-06, amendment 39-14576 (71 FR 25926, May 3, 2006).
The existing AD applies to certain Boeing Model 747-100, 747-100B, 747-
100B SUD, 747-200B, 747-300, 747-400, 747-400D, and 747SR series
airplanes. The proposed AD was published in the Federal Register on
July 13, 2006 (71 FR 39600) to require repetitive inspections to detect
cracking of certain lower lobe fuselage frames, and repair if
necessary, and to specify appropriate service information for certain
corrective actions.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
Support for the Proposed AD
Boeing supports the proposed AD.
Request To Change Incorporation of Certain Information
The Modification and Replacement Parts Association (MARPA) states
that, typically, airworthiness directives are based on service
information originating with the type certificate holder or its
suppliers. MARPA adds that manufacturer service documents are
[[Page 70858]]
privately authored instruments generally having copyright protection
against duplication and distribution. MARPA notes that when a service
document is incorporated by reference into a public document, such as
an airworthiness directive, it loses its private, protected status and
becomes a public document. MARPA adds that if a service document is
used as a mandatory element of compliance, it should not simply be
referenced, but should be incorporated into the regulatory document; by
definition, public laws must be public, which means they cannot rely
upon private writings. MARPA is concerned that the failure to
incorporate essential service information could result in a court
decision invalidating the AD.
MARPA adds that incorporated by reference service documents should
be made available to the public by publication in the Docket Management
System (DMS), keyed to the action that incorporates them. MARPA notes
that the stated purpose of the incorporation by reference method is
brevity, to keep from expanding the Federal Register needlessly by
publishing documents already in the hands of the affected individuals;
traditionally, ``affected individuals'' means aircraft owners and
operators, who are generally provided service information by the
manufacturer. MARPA adds that a new class of affected individuals has
emerged, since the majority of aircraft maintenance is now performed by
specialty shops instead of aircraft owners and operators. MARPA notes
that this new class includes maintenance and repair organizations,
component servicing and repair shops, parts purveyors and distributors,
and organizations manufacturing or servicing alternatively certified
parts under 14 CFR 21.303 (parts manufacturer approval (PMA)). MARPA
adds that the concept of brevity is now nearly archaic as documents
exist more frequently in electronic format than on paper. Therefore,
MARPA asks that the service documents deemed essential to the
accomplishment of the NPRM be incorporated by reference into the
regulatory instrument, and published in the DMS.
We do not agree that documents should be incorporated by reference
during the NPRM phase of rulemaking. The Office of the Federal Register
(OFR) requires that documents that are necessary to accomplish the
requirements of the AD be incorporated by reference during the final
rule phase of rulemaking. This final rule incorporates by reference the
document necessary for the accomplishment of the requirements mandated
by this AD. Further, we point out that while documents that are
incorporated by reference do become public information, they do not
lose their copyright protection. For that reason, we advise the public
to contact the manufacturer to obtain copies of the referenced service
information.
Additionally, we do not publish service documents in DMS. We are
currently reviewing our practice of publishing proprietary service
information. Once we have thoroughly examined all aspects of this
issue, and have made a final determination, we will consider whether
our current practice needs to be revised. However, we consider that to
delay this AD action for that reason would be inappropriate, since we
have determined that an unsafe condition exists and that the
requirements in this AD must be accomplished to ensure continued
safety. Therefore, we have not changed the AD in this regard.
Explanation of Change to Heading
We have revised the heading, ``RESTATEMENT OF THE REQUIREMENTS OF
AD 99-07-12, WITH ADDITIONAL INFORMATION FOR GROUP 2 AIRPLANES,'' to
state, ``* * * WITH COMPLIANCE TIMES FOR GROUP 2 AIRPLANES.'' This
change provides more information about the new requirements of this AD.
Conclusion
We have carefully reviewed the available data, including the
comments received, and determined that air safety and the public
interest require adopting the AD with the change described previously.
We have determined that this change will neither increase the economic
burden on any operator nor increase the scope of the AD.
Costs of Compliance
There are about 681 airplanes of the affected design in the
worldwide fleet. This AD affects about 99 airplanes of U.S. registry.
The new requirements of this AD add no additional economic burden. The
current costs for this AD are repeated for the convenience of affected
operators, as follows:
The actions in this AD take about 2 work hours per airplane, at an
average labor rate of $80 per work hour. Based on these figures, the
estimated cost of both the retained and new actions for U.S. operators
is $15,840, or $160 per airplane, per inspection cycle.
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.

accomplished; whichever occurs later.
Note 2: 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.''
Repetitive Inspections
(g) If no cracking is detected during the inspection required by
paragraph (f) of this AD, repeat the inspection thereafter at
intervals not to exceed 3,000 flight cycles.
Corrective Actions
(h) If any cracking is detected during any inspection required
by paragraph (f) of this AD, prior to further flight, accomplish
paragraphs (h)(1) and (h)(2) of this AD:
(1) Within 20 inches of the crack location on the frame, perform
a detailed inspection of the adjacent structure to detect cracking.
As of June 7, 2006, the detailed inspection must be done in
accordance with Boeing Alert Service Bulletin 747-53A2408, Revision
1, dated April 4, 2002. If any cracking is detected during any
detailed inspection done in accordance with paragraph (f) or (h)(1)
of this AD, prior to further flight, repair in accordance with
paragraph (h)(1)(i) or (h)(1)(ii) of this AD, as applicable.
(i) For Group 1 airplanes: Using a method approved in accordance

thereafter at intervals not to exceed 3,000 flight cycles.
Optional Terminating Inspection
(i) Accomplishment of the initial detailed inspection of the
Section 46 lower lobe frames required by paragraph (f)(2) or (i)(2)
of AD 2005-20-30 constitutes terminating action for the requirements
of this AD only for airplanes identified in Boeing Alert Service
Bulletin 747-53A2408, Revision 1, dated April 4, 2002, as Group 1
airplanes. Accomplishment of the initial detailed inspection of the
Section 46 lower lobe frames required by paragraph (f) of AD 2006-
05-02 constitutes terminating action for the requirements of this AD
only for airplanes identified in Boeing Alert Service Bulletin 747-
53A2408, Revision 1, dated April 4, 2002, as Group 2 airplanes.
Alternative Methods of Compliance (AMOCs)
(j)(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) Before using any AMOC approved in accordance with Sec.
39.19 on any airplane to which the AMOC applies, notify the
appropriate principal inspector in the FAA Flight Standards
Certificate Holding District Office.
(3) 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 Commercial Airplanes
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.
