AGENCY:
The FAA proposes to
supersede Airworthiness Directive (AD)
2018–16–05, which applies to all The
Boeing Company Model 757–200,
–200PF, –200CB, and –300 series
airplanes. AD 2018–16–05 requires
repetitive inspections for skin cracking
and shim migration at the upper link
drag fittings, diagonal brace cracking,
and fastener looseness; and applicable
on-condition actions. Since the FAA
issued AD 2018–16–05, an operator
reported finding multiple cracks in the
drag fitting at fastener holes while
inspecting for cracking as required by
AD 2018–16–05. This proposed AD
would retain the actions required by AD
2018–16–05, reduce the compliance
times for certain inspections, and add
repetitive inspections at certain fastener
hole locations and applicable oncondition actions. The FAA is
proposing this AD to address the unsafe
condition on these products.

Discussion
The FAA issued AD 2018–16–05,
Amendment 39–19345 (83 FR 38250,
August 6, 2018) (‘‘AD 2018–16–05’’), for
all The Boeing Company Model 757–
200, –200PF, –200CB, and –300 series
airplanes. AD 2018–16–05 requires
repetitive inspections for skin cracking
and shim migration at the upper link
drag fittings, diagonal brace cracking,
and fastener looseness; and applicable
on-condition actions. AD 2018–16–05
resulted from reports of bolt rotation in
the engine drag fitting joint and fastener
heads; an inspection of the fastener
holes revealed that cracks were found in
the skin on two airplanes. The FAA
issued AD 2018–16–05 to address
cracking in the wing upper skin and
forward drag fittings, which could lead
to a compromised upper link and
reduced structural integrity of the
engine strut.
Actions Since AD 2018–16–05 Was
Issued
Since the FAA issued AD 2018–16–
05, an operator reported finding
multiple cracks in the drag fitting at the
fastener holes while inspecting for
cracking as required by AD 2018–16–05.
Subsequent analysis determined that
additional repetitive open-hole high
frequency eddy current (HFEC)
inspections for cracking are necessary at
the forward rows of fastener holes.
Based on findings, it was also
determined that more frequent
inspections for cracking in the diagonal
brace and diagonal brace fittings are
necessary.

2018–16–05. Those requirements are
referenced in the service information
identified previously, which, in turn, is
referenced in paragraph (g) of this
proposed AD. This proposed AD would
also require accomplishment of the
actions identified in the
Accomplishment Instructions of Boeing
Alert Requirements Bulletin 757–
57A0073 RB, Revision 1, dated August
1, 2019, described previously.

and compliance times, see this service
information at https://

including general visual, detailed, and
HFEC inspections, for loose fasteners,
skin cracking, and shim migration at the
upper link drag fittings and for cracking
in the diagonal brace and diagonal brace
fittings and applicable on-condition
actions. This service information is
reasonably available because the
interested parties have access to it
through their normal course of business
or by the means identified in the
ADDRESSES section.
FAA’s Determination
The FAA is proposing this AD
because the FAA 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
Although this proposed AD does not
explicitly restate the requirements of AD
2018–16–05, this proposed AD would
Explanation of Requirements Bulletin
The FAA worked in conjunction with
industry, under the Airworthiness
Directive Implementation Aviation
Rulemaking Committee (AD ARC), to
enhance the AD system. One
enhancement is a process for annotating
68823
which steps in the service information
are ‘‘required for compliance’’ (RC) with
an AD. Boeing has implemented this RC
concept into Boeing service bulletins.
In an effort to further improve the
quality of ADs and AD-related Boeing
service information, a joint process
improvement initiative was worked
between the FAA and Boeing. The
initiative resulted in the development of
a new process in which the service
information more clearly identifies the
actions needed to address the unsafe
condition in the ‘‘Accomplishment
Instructions.’’ The new process results
in a Boeing Requirements Bulletin,
which contains only the actions needed
to address the unsafe condition (i.e.,
only the RC actions).
Costs of Compliance
The FAA estimates that this proposed
AD affects 561 airplanes of U.S. registry.
The FAA estimates the following costs
to comply with this proposed AD:
ESTIMATED COSTS FOR REQUIRED ACTIONS
Action
Labor cost
Repetitive inspections (retained actions from AD 2018–16–05).
Repetitive HFEC inspections (new
proposed action).
83 work-hours × $85 per hour =
$7,055 per inspection cycle.
2 work-hours × $85 per hour =
$170 per inspection cycle.
The FAA has received no definitive
data that would enable the FAA to
provide cost estimates for the oncondition actions specified in 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.
The FAA is 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.
This proposed AD is issued in
accordance with authority delegated by

the Executive Director, Aircraft
Certification Service, as authorized by
FAA Order 8000.51C. In accordance
with that order, issuance of ADs is
normally a function of the Compliance
and Airworthiness Division, but during
this transition period, the Executive
Director has delegated the authority to
issue ADs applicable to transport
category airplanes and associated
appliances to the Director of the System
Oversight Division.
Regulatory Findings
The FAA has 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) Will not affect intrastate aviation
in Alaska, and
(3) Will not have a significant
economic impact, positive or negative,

fittings, which could lead to a compromised upper link and reduced
structural integrity of the engine strut.
Actions Since AD 2018-16-05 Was Issued
Since the FAA issued AD 2018-16-05, an operator reported finding
multiple cracks in the drag fitting at the fastener holes while
inspecting for cracking as required by AD 2018-16-05. Subsequent
analysis determined that additional repetitive open-hole high frequency
eddy current (HFEC) inspections for cracking are necessary at the
forward rows of fastener holes. Based on findings, it was also
determined that more frequent inspections for cracking in the diagonal
brace and diagonal brace fittings are necessary.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Alert Requirements Bulletin 757-57A0073 RB,
Revision 1, dated August 1, 2019. This service information describes
procedures for repetitive inspections,
[[Page 68823]]
including general visual, detailed, and HFEC inspections, for loose
fasteners, skin cracking, and shim migration at the upper link drag
fittings and for cracking in the diagonal brace and diagonal brace
fittings and applicable on-condition actions. This service information
is reasonably available because the interested parties have access to
it through their normal course of business or by the means identified
in the ADDRESSES section.
FAA's Determination
The FAA is proposing this AD because the FAA 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
Although this proposed AD does not explicitly restate the
requirements of AD 2018-16-05, this proposed AD would retain all of the
requirements of AD 2018-16-05. Those requirements are referenced in the
service information identified previously, which, in turn, is
referenced in paragraph (g) of this proposed AD. This proposed AD would
also require accomplishment of the actions identified in the
Accomplishment Instructions of Boeing Alert Requirements Bulletin 757-
57A0073 RB, Revision 1, dated August 1, 2019, described previously.
For information on the procedures and compliance times, see this
service information at https://www.regulations.gov by searching for and
locating Docket No. FAA-2019-0984.
Explanation of Requirements Bulletin
The FAA worked in conjunction with industry, under the
Airworthiness Directive Implementation Aviation Rulemaking Committee
(AD ARC), to enhance the AD system. One enhancement is a process for
annotating which steps in the service information are ``required for
compliance'' (RC) with an AD. Boeing has implemented this RC concept
into Boeing service bulletins.
In an effort to further improve the quality of ADs and AD-related
Boeing service information, a joint process improvement initiative was
worked between the FAA and Boeing. The initiative resulted in the
development of a new process in which the service information more
clearly identifies the actions needed to address the unsafe condition
in the ``Accomplishment Instructions.'' The new process results in a
Boeing Requirements Bulletin, which contains only the actions needed to
address the unsafe condition (i.e., only the RC actions).
Costs of Compliance
The FAA estimates that this proposed AD affects 561 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost on U.S.

----------------------------------------------------------------------------------------------------------------
Repetitive inspections (retained 83 work-hours x $85 $0 $7,055 per $3,957,855 per
actions from AD 2018-16-05). per hour = $7,055 inspection cycle. inspection cycle.

The FAA has received no definitive data that would enable the FAA
to provide cost estimates for the on-condition actions specified in
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.
The FAA is 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.
This proposed AD is issued in accordance with authority delegated
by the Executive Director, Aircraft Certification Service, as
authorized by FAA Order 8000.51C. In accordance with that order,
issuance of ADs is normally a function of the Compliance and
Airworthiness Division, but during this transition period, the
Executive Director has delegated the authority to issue ADs applicable
to transport category airplanes and associated appliances to the
Director of the System Oversight Division.
Regulatory Findings
The FAA has 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) Will not affect intrastate aviation in Alaska, 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.
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
