(a) Comments Due Date
We must receive comments by May 9,
2014.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all Dassault Aviation
Model FALCON 7X airplanes, certificated in
any category.
(d) Subject
Air Transport Association (ATA) of
America Code 32, Main Landing Gear.
(e) Reason
This AD was prompted by reports that the
pintle pins installed on a certain number of
airplanes may be incorrectly protected
against corrosion. We are issuing this AD to
detect and correct pintle pins that have been
incorrectly corrosion-protected, which could
cause the pintle pins to shear under normal
load and lead to the collapse of the MLG
during take-off or landing.

ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to supersede
Airworthiness Directive (AD) 2005–13–
05, which applies to certain Boeing
Model 747–400F series airplanes. AD
2005–13–05 currently requires
inspections for cracking of the web,
upper chord, and upper chord strap of
the upper deck floor beams, and repair
of any cracking. AD 2005–13–05 also
requires a preventive modification of
the upper deck floor beams, and
repetitive inspections for cracking after
accomplishing the modification. Since
we issued AD 2005–13–05, the upper
chords of the upper deck floor beams at
certain stations have been determined to
be structures that are susceptible to
widespread fatigue damage, and certain
airplanes with an initial modification
require a second modification for the
airplane to meet its limit of validity
(LOV). This proposed AD would require
that second modification and repetitive
inspections for cracking and repair if
necessary. We are proposing this AD to
detect and correct fatigue cracking in
certain upper chords of the upper deck
floor beam, which could result in
reduced structural integrity of the
airplane and rapid decompression or
reduced controllability of the airplane.
DATES: We must receive comments on
this proposed AD by May 9, 2014.

Discussion
Structural fatigue damage is
progressive. It begins as minute cracks,
and those cracks grow under the action
of repeated stresses. This can happen
because of normal operational
conditions and design attributes, or
because of isolated situations or
incidents such as material defects, poor
fabrication quality, or corrosion pits,
dings, or scratches. Fatigue damage can
occur locally, in small areas or
structural design details, or globally.
Global fatigue damage is general
degradation of large areas of structure
with similar structural details and stress
levels. Multiple-site damage is global
damage that occurs in a large structural
element such as a single rivet line of a
lap splice joining two large skin panels.
Global damage can also occur in
multiple elements such as adjacent
frames or stringers. Multiple-sitedamage and multiple-element-damage
cracks are typically too small initially to
be reliably detected with normal
inspection methods. Without
intervention, these cracks will grow,
and eventually compromise the
structural integrity of the airplane, in a
condition known as widespread fatigue
damage (WFD). As an airplane ages,
WFD will likely occur, and will
certainly occur if the airplane is
operated long enough without any
intervention.
The FAA’s WFD final rule (75 FR
69746, November 15, 2010) became
effective on January 14, 2011. The WFD
rule requires certain actions to prevent
structural failure due to WFD
throughout the operational life of
certain existing transport category
airplanes and all of these airplanes that
will be certificated in the future. For
existing and future airplanes subject to
the WFD rule, the rule requires that
design approval holders (DAHs)
establish LOV of the engineering data
that support the structural maintenance
program. Operators affected by the WFD
rule may not fly an airplane beyond its
LOV, unless an extended LOV is
approved.
The WFD rule (75 FR 69746,
November 15, 2010) does not require
identifying and developing maintenance
PO 00000
Frm 00007
Fmt 4702
Sfmt 4702
actions if the DAHs can show that such
actions are not necessary to prevent
WFD before the airplane reaches the
LOV. Many LOVs, however, do depend
on accomplishment of future
maintenance actions. As stated in the
WFD rule, any maintenance actions
necessary to reach the LOV will be
mandated by airworthiness directives
through separate rulemaking actions.
In the context of WFD, this action is
necessary to enable DAHs to propose
LOVs that allow operators the longest
operational lives for their airplanes, and
still ensure that WFD will not occur.
This approach allows for an
implementation strategy that provides
flexibility to DAHs in determining the
timing of service information
development (with FAA approval),
while providing operators with certainty
regarding the LOV applicable to their
airplanes.
On June 10, 2005, we issued AD
2005–13–05, Amendment 39–14141 (70
FR 35989, June 22, 2005) for certain
Boeing Model 747–400F series
airplanes. AD 2005–13–05 requires
initial detailed and open-hole high
frequency eddy current inspections for
cracking of the web, upper chord, and
upper chord strap of the upper deck
floor beams, and repair of any cracking.
AD 2005–13–05 also requires a
preventive modification of the upper
deck floor beams, and repetitive
inspections for cracking after
accomplishing the modification. AD
2005–13–05 resulted from reports of
fatigue cracking found on the upper
deck floor beam to frame attachment
points. We issued AD 2005–13–05 to
prevent fatigue cracks in the upper
chord, upper chord strap, and the web
of the upper deck floor beams and
resultant failure of the floor beams.
Actions Since AD 2005–13–05,
Amendment 39–14141 (70 FR 35989,
June 22, 2005) Was Issued
Since we issued AD 2005–13–05,
Amendment 39–14141 (70 FR 35989,
June 22, 2005), we received reports that
indicate that the upper chords of the
upper deck floor beams at stations
(STA) 340 through 520 have been
determined to be structures that are
susceptible to widespread fatigue
damage, and airplanes that had an
initial modification done before 15,000
total flight cycles require a second
fastener hole zero-timing modification
for the airplane to meet its LOV.
Relevant Service Information
We reviewed Boeing Service Bulletin
747–53A2443, Revision 2, dated August
2, 2013. For information on the
procedures and compliance times, see

www.regulations.gov by searching for
Docket No. FAA–2014–0170.
FAA’s Determination
We are proposing this AD because we
evaluated all the relevant information
and determined the unsafe condition
described previously is likely to exist or
develop in other products of the same
type design.
Proposed AD Requirements
This proposed AD would retain all of
the requirements of AD 2005–13–05,
Amendment 39–14141 (70 FR 35989,
June 22, 2005). This proposed AD
would also require accomplishing the
actions specified in the service
information described previously.
Difference Between This Proposed AD
and Service Information
The service bulletin specifies to
contact the manufacturer for
instructions on how to repair certain
conditions, but this proposed AD would
require repairing those conditions in
one of the following ways:
• In accordance with a method that
we approve; or
• Using data that meet the
certification basis of the airplane, and
that have been approved by the Boeing
Commercial Airplanes Organization
Designation Authorization (ODA) whom
we have authorized to make those
findings.
Explanation of Compliance Time
The compliance time for the
modification specified in this proposed
AD for addressing WFD was established
to ensure that discrepant structure is
modified before WFD develops in
airplanes. Standard inspection
techniques cannot be relied on to detect
WFD before it becomes a hazard to
flight. We will not grant any extensions
of the compliance time to complete any
AD-mandated service bulletin related to
WFD without extensive new data that
would substantiate and clearly warrant
such an extension.
Costs of Compliance
We estimate that this proposed AD
affects 13 airplanes of U.S. registry.
We estimate the following costs 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

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),
(3) Will not affect intrastate aviation
in Alaska, and
(4) Will not have a significant
economic impact, positive or negative,

-----------------------------------------------------------------------
SUMMARY: We propose to supersede Airworthiness Directive (AD) 2005-13-
05, which applies to certain Boeing Model 747-400F series airplanes. AD
2005-13-05 currently requires inspections for cracking of the web,
upper chord, and upper chord strap of the upper deck floor beams, and
repair of any cracking. AD 2005-13-05 also requires a preventive
modification of the upper deck floor beams, and repetitive inspections
for cracking after accomplishing the modification. Since we issued AD
2005-13-05, the upper chords of the upper deck floor beams at certain
stations have been determined to be structures that are susceptible to
widespread fatigue damage, and certain airplanes with an initial
modification require a second modification for the airplane to meet its
limit of validity (LOV). This proposed AD would require that second
modification and repetitive inspections for cracking and repair if
necessary. We are proposing this AD to detect and correct fatigue
cracking in certain upper chords of the upper deck floor beam, which
could result in reduced structural integrity of the airplane and rapid
decompression or reduced controllability of the airplane.

Discussion
Structural fatigue damage is progressive. It begins as minute
cracks, and those cracks grow under the action of repeated stresses.
This can happen because of normal operational conditions and design
attributes, or because of isolated situations or incidents such as
material defects, poor fabrication quality, or corrosion pits, dings,
or scratches. Fatigue damage can occur locally, in small areas or
structural design details, or globally. Global fatigue damage is
general degradation of large areas of structure with similar structural
details and stress levels. Multiple-site damage is global damage that
occurs in a large structural element such as a single rivet line of a
lap splice joining two large skin panels. Global damage can also occur
in multiple elements such as adjacent frames or stringers. Multiple-
site-damage and multiple-element-damage cracks are typically too small
initially to be reliably detected with normal inspection methods.
Without intervention, these cracks will grow, and eventually compromise
the structural integrity of the airplane, in a condition known as
widespread fatigue damage (WFD). As an airplane ages, WFD will likely
occur, and will certainly occur if the airplane is operated long enough
without any intervention.
The FAA's WFD final rule (75 FR 69746, November 15, 2010) became
effective on January 14, 2011. The WFD rule requires certain actions to
prevent structural failure due to WFD throughout the operational life
of certain existing transport category airplanes and all of these
airplanes that will be certificated in the future. For existing and
future airplanes subject to the WFD rule, the rule requires that design
approval holders (DAHs) establish LOV of the engineering data that
support the structural maintenance program. Operators affected by the
WFD rule may not fly an airplane beyond its LOV, unless an extended LOV
is approved.
The WFD rule (75 FR 69746, November 15, 2010) does not require
identifying and developing maintenance actions if the DAHs can show
that such actions are not necessary to prevent WFD before the airplane
reaches the LOV. Many LOVs, however, do depend on accomplishment of
future maintenance actions. As stated in the WFD rule, any maintenance
actions necessary to reach the LOV will be mandated by airworthiness
directives through separate rulemaking actions.
In the context of WFD, this action is necessary to enable DAHs to
propose LOVs that allow operators the longest operational lives for
their airplanes, and still ensure that WFD will not occur. This
approach allows for an implementation strategy that provides
flexibility to DAHs in determining the timing of service information
development (with FAA approval), while providing operators with
certainty regarding the LOV applicable to their airplanes.
On June 10, 2005, we issued AD 2005-13-05, Amendment 39-14141 (70
FR 35989, June 22, 2005) for certain Boeing Model 747-400F series
airplanes. AD 2005-13-05 requires initial detailed and open-hole high
frequency eddy current inspections for cracking of the web, upper
chord, and upper chord strap of the upper deck floor beams, and repair
of any cracking. AD 2005-13-05 also requires a preventive modification
of the upper deck floor beams, and repetitive inspections for cracking
after accomplishing the modification. AD 2005-13-05 resulted from
reports of fatigue cracking found on the upper deck floor beam to frame
attachment points. We issued AD 2005-13-05 to prevent fatigue cracks in
the upper chord, upper chord strap, and the web of the upper deck floor
beams and resultant failure of the floor beams.
Actions Since AD 2005-13-05, Amendment 39-14141 (70 FR 35989, June 22,
2005) Was Issued
Since we issued AD 2005-13-05, Amendment 39-14141 (70 FR 35989,
June 22, 2005), we received reports that indicate that the upper chords
of the upper deck floor beams at stations (STA) 340 through 520 have
been determined to be structures that are susceptible to widespread
fatigue damage, and airplanes that had an initial modification done
before 15,000 total flight cycles require a second fastener hole zero-
timing modification for the airplane to meet its LOV.
Relevant Service Information
We reviewed Boeing Service Bulletin 747-53A2443, Revision 2, dated
August 2, 2013. For information on the procedures and compliance times,
see
[[Page 16243]]
this service information at https://www.regulations.gov by searching for
Docket No. FAA-2014-0170.
FAA's Determination
We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
Proposed AD Requirements
This proposed AD would retain all of the requirements of AD 2005-
13-05, Amendment 39-14141 (70 FR 35989, June 22, 2005). This proposed
AD would also require accomplishing the actions specified in the
service information described previously.
Difference Between This Proposed AD and Service Information
The service bulletin specifies to contact the manufacturer for
instructions on how to repair certain conditions, but this proposed AD
would require repairing those conditions in one of the following ways:
In accordance with a method that we approve; or
Using data that meet the certification basis of the
airplane, and that have been approved by the Boeing Commercial
Airplanes Organization Designation Authorization (ODA) whom we have
authorized to make those findings.
Explanation of Compliance Time
The compliance time for the modification specified in this proposed
AD for addressing WFD was established to ensure that discrepant
structure is modified before WFD develops in airplanes. Standard
inspection techniques cannot be relied on to detect WFD before it
becomes a hazard to flight. We will not grant any extensions of the
compliance time to complete any AD-mandated service bulletin related to
WFD without extensive new data that would substantiate and clearly
warrant such an extension.
Costs of Compliance
We estimate that this proposed AD affects 13 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:

----------------------------------------------------------------------------------------------------------------
We have received no definitive data that would enable us to provide
cost estimates for the on-condition actions specified in this proposed
AD. We have no way of determining the number of products that may need
these actions.
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),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, 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
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. Amend Sec. 39.13 by removing Airworthiness Directive (AD) 2005-13-
05, Amendment 39-14141 (70 FR 35989, June 22, 2005), and adding the
following new AD:
[[Page 16244]]
The Boeing Company: Docket No. FAA-2014-0170; Directorate Identifier
2013-NM-169-AD.
(a) Comments Due Date
The FAA must receive comments on this AD action by May 9, 2014.
(b) Affected ADs
This AD supersedes AD 2005-13-05, Amendment 39-14141 (70 FR
35989, June 22, 2005).
(c) Applicability
This AD applies to The Boeing Company Model 747-400F series
airplanes, certificated in any category, as identified in Boeing
Service Bulletin 747-53A2443, Revision 2, dated August 2, 2013.
(d) Subject
Air Transport Association (ATA) of America Code 53, Fuselage.
(e) Unsafe Condition
This AD was prompted by a report indicating that the upper
chords of the upper deck floor floor beams at stations (STA) 340
through 520 have been determined to be structures that are
susceptible to widespread fatigue damage, and airplanes that had an
initial modification done before 15,000 total flight cycles require
a second fastener hole zero-timing modification for the airplane to
meet its limit of validity (LOV). We are issuing this AD to detect
and correct fatigue cracking in certain upper chords of the upper
deck floor beam, which could result in reduced structural integrity
of the airplane and rapid decompression or reduced controllability
of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Retained Inspections With Revised Service Information
This paragraph restates the requirements of paragraph (g) of AD
