Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to
supersede Airworthiness Directive (AD)
2019–22–10, which applies to all The
Boeing Company Model 737–600, –700,
–700C, –800, –900, and –900ER series
airplanes. AD 2019–22–10 requires
repetitive inspections for cracking of the
left- and right-hand side outboard
chords of frame fittings and failsafe
straps at a certain station around eight
fasteners, and repair if any cracking is
found. Since the FAA issued AD 2019–
22–10, it was determined that the initial
inspection threshold and repetitive
inspection interval are inadequate to
address the cracking in a timely manner.
For certain airplanes, this proposed AD
would reduce the compliance time for
the initial inspection, and for all
airplanes this proposed AD would
reduce the compliance time for the
repetitive inspections. The FAA is
proposing this AD to address the unsafe
condition on these products.
DATES: The FAA must receive comments
on this proposed AD by October 23,
2020.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following

Discussion
The FAA issued AD 2019–22–10,
Amendment 39–19789 (84 FR 61533,
November 13, 2019) (‘‘AD 2019–22–
10’’), for all The Boeing Company Model
737–600, –700, –700C, –800, –900, and
–900ER series airplanes. AD 2019–22–
10 requires inspections for cracking of
the left- and right-hand side outboard
chords of frame fittings and failsafe
straps at a certain station around eight
fasteners, and repair if any cracking is
found. AD 2019–22–10 superseded AD
2019–20–02 Amendment 39–19755 (84
FR 52754, October 3, 2019) (‘‘AD 2019–
20–02’’). AD 2019–22–10 resulted from
reports of cracking discovered in the
left- and right-hand side outboard
chords of the station (STA) 663.75 frame

fittings and failsafe straps adjacent to
the stringer S–18A straps and a
determination that the inspection area
specified in AD 2019–20–02 needed to
be expanded. The FAA issued AD 2019–
22–10 to address cracking in the STA
663.75 frame fitting outboard chords
and failsafe straps adjacent to the
stringer S–18A straps, which could
result in failure of a Principal Structural
Element (PSE) to sustain limit load. This
condition could adversely affect the
structural integrity of the airplane and
result in loss of control of the airplane.
Actions Since AD 2019–22–10 Was
Issued
Since the FAA issued AD 2019–22–
10, it was determined by an engineering
analysis of the inspection reporting
results and metallurgical evaluation of
the submitted frame fitting assemblies
that the initial inspection threshold for
Model 737–900ER series airplanes, and
the repetitive inspection interval for all
affected airplanes is inadequate to
address the cracking in a timely manner.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Boeing MultiOperator Message MOM–MOM–20–
0443–01B (R1), dated June 2, 2020. This
service information describes
procedures for repetitive detailed
inspections for cracking of the left- and
right-hand side outboard chords of the
STA 663.75 frame fittings and failsafe
straps around eight fasteners adjacent to
the stringer S–18A straps.
This proposed AD also requires
Boeing Multi-Operator Message MOM–
MOM–19–0536–01B, dated September
30, 2019, which the Director of the
Federal Register approved for
incorporation by reference as of October
3, 2019 (84 FR 52754, October 3, 2019).
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 agency 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 requires repetitive
inspections for cracking of the left- and
right-hand side outboard chords of the
STA 663.75 frame fittings and failsafe
straps around eight fasteners adjacent to
the stringer S–18A straps. This
PO 00000
Frm 00005
Fmt 4702
Sfmt 4702
proposed AD also requires repair of all
cracking using a method approved by
the FAA or The Boeing Company
Organization Designation Authorization
(ODA). Accomplishing the initial
inspection required by paragraph (i) of
this proposed AD would terminate the
inspections originally required by
paragraph (g) of AD 2019–22–10, which
are retained in this proposed AD (the
associated reporting specified in
paragraph (h) of AD 2019–22–10 is also
retained in this proposed AD). This
proposed AD would also require
sending a report of all results of the
initial inspections specified in
paragraph (i) of this proposed AD to
Boeing.
Although this proposed AD does not
explicitly restate the requirements of
paragraphs (i), (j), and (k) of AD 2019–
22–10, this proposed AD would retain
those requirements with certain revised
compliance times. Those requirements
are referenced in Boeing Multi-Operator
Message MOM–MOM–20–0443–01B
(R1), dated June 2, 2020, which, in turn,
is referenced in paragraphs (i) and (l) of
this proposed AD.
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–2020–
0789.
Explanation of New Compliance Times
for Certain Configurations
For Boeing Model 737–600, –700,
–700C, –800, and –900 series airplanes
having less than 22,600 total flight
cycles and on which an inspection
specified in Boeing Multi-Operator
Message MOM–MOM–19–0623–01B,
dated November 5, 2019, has been done;
and for Boeing Model 737–900ER series
airplanes having less than 14,000 total
flight cycles and on which an inspection
specified in Boeing Multi-Operator
Message MOM–MOM–19–0623–01B,
dated November 5, 2019, has been done,
the compliance times specified in
Boeing Multi-Operator Message MOM–
MOM–20–0443–01B (R1), dated June 2,
2020 (which will be required by this
proposed AD), are relieving as
compared to the compliance times in
Boeing Multi-Operator Message MOM–
MOM–19–0623–01B, dated November 5,
2019 (which is required by AD 2019–
22–10).
For example, for a Boeing Model 737–
600 series airplane on which the
inspection was done and the airplane
had accumulated 15,000 total flight
cycles, the next inspection required by
AD 2019–22–10 would be at 18,500 total
flight cycles (i.e., 3,500 flight cycles
after the inspection as specified in
E:\FR\FM\08SEP1.SGM
08SEP1
Federal Register / Vol. 85, No. 174 / Tuesday, September 8, 2020 / Proposed Rules
Boeing Multi-Operator Message MOM–
MOM–19–0623–01B, dated November 5,
2019).
However, as specified in Boeing
Multi-Operator Message MOM–MOM–
20–0443–01B (R1), dated June 2, 2020,
the next inspection for that airplane is
prior to 22,600 total flight cycles or
within 1,500 flight cycles from the last
inspection in accordance with MOM–
MOM–19–0623–01B, or within 30 days
from the original issue date of MOM–
MOM–20–0443–01B (R1) (which would
correspond to 30 days after the effective
date of the final rule for this proposed
AD), whichever occurs latest.
In conclusion, if the inspection was
done early, operators do not have to do
the next inspection at the 3,500 interval
required by AD 2019–22–10 after this
proposed AD is a final rule; instead
operators would then do the next
inspection within the new compliance
times specified in Boeing MultiOperator Message MOM–MOM–20–
0443–01B R1), dated June 2, 2020, for
their configuration.
Interim Action
The FAA considers this proposed AD
interim action. The inspection reports
that are required by this proposed AD
55393
will enable the manufacturer to obtain
better insight into the nature, cause, and
extent of the cracking, and eventually to
develop final action to address the
unsafe condition. Once final action has
been identified, the FAA might consider
further rulemaking.
Costs of Compliance
The FAA estimates that this proposed
AD affects 1,911 airplanes of U.S.
registry. The FAA estimates the
following costs to comply with this
proposed AD:

The FAA has received no definitive
data that would enable the agency to
provide cost estimates for the oncondition actions specified in this
proposed AD.
Paperwork Reduction Act
A federal agency may not conduct or
sponsor, and a person is not required to
respond to, nor shall a person be subject
to penalty for failure to comply with a
collection of information subject to the
requirements of the Paperwork
Reduction Act unless that collection of
information displays a current valid
OMB control number. The control
number for the collection of information
required by this proposed AD is 2120–
0056. The paperwork cost associated
with this proposed AD has been
detailed in the Costs of Compliance
section of this document and includes
time for reviewing instructions, as well
as completing and reviewing the
collection of information. Therefore, all
reporting associated with this proposed
AD is mandatory. Comments concerning
the accuracy of this burden and
suggestions for reducing the burden
should be directed to Information

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.
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,
Frm 00006
Fmt 4702
(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.

straps and a determination that the initial
inspection threshold for certain airplanes and
the repetitive inspection interval specified in

cracking in a timely manner. The FAA is
issuing this AD to address cracking in the
STA 663.75 frame fitting outboard chords
and failsafe straps adjacent to the stringer S–
18A straps, which could result in failure of
a Principal Structural Element (PSE) to

RIN 2120-AA64
Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2019-22-10, which applies to all The Boeing Company Model 737-600, -
700, -700C, -800, -900, and -900ER series airplanes. AD 2019-22-10
requires repetitive inspections for cracking of the left- and right-
hand side outboard chords of frame fittings and failsafe straps at a
certain station around eight fasteners, and repair if any cracking is
found. Since the FAA issued AD 2019-22-10, it was determined that the
initial inspection threshold and repetitive inspection interval are
inadequate to address the cracking in a timely manner. For certain
airplanes, this proposed AD would reduce the compliance time for the
initial inspection, and for all airplanes this proposed AD would reduce
the compliance time for the repetitive inspections. The FAA is
proposing this AD to address the unsafe condition on these products.
DATES: The FAA must receive comments on this proposed AD by October 23,
2020.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

[[Page 55392]]
FAA-2020-0789; Project Identifier AD-2020-00849-T'' at the beginning of
your comments.
Except for Confidential Business Information (CBI) as described in
the following paragraph, and other information as described in 14 CFR
11.35, the FAA will post all comments received, without change, as well
as a report summarizing each substantive public contact with FAA
personnel concerning this proposed rulemaking. Before acting on this
proposal, the FAA will consider all comments received by the closing

comment period has closed if it is possible to do so without incurring
expense or delay. The FAA may change this NPRM because of those
comments.
Confidential Business Information
CBI is commercial or financial information that is both customarily
and actually treated as private by its owner. Under the Freedom of
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public
disclosure. If your comments responsive to this NPRM contain commercial
or financial information that is customarily treated as private, that
you actually treat as private, and that is relevant or responsive to
this NPRM, it is important that you clearly designate the submitted
comments as CBI. Please mark each page of your submission containing
CBI as ``PROPIN.'' The FAA will treat such marked submissions as
confidential under the FOIA, and they will not be placed in the public
docket of this NPRM. Submissions containing CBI should be sent to the
person identified in the FOR FURTHER INFORMATION CONTACT section. Any
commentary that the FAA receives which is not specifically designated
as CBI will be placed in the public docket for this rulemaking.
Discussion
The FAA issued AD 2019-22-10, Amendment 39-19789 (84 FR 61533,
November 13, 2019) (``AD 2019-22-10''), for all The Boeing Company
Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. AD
2019-22-10 requires inspections for cracking of the left- and right-
hand side outboard chords of frame fittings and failsafe straps at a
certain station around eight fasteners, and repair if any cracking is
found. AD 2019-22-10 superseded AD 2019-20-02 Amendment 39-19755 (84 FR
52754, October 3, 2019) (``AD 2019-20-02''). AD 2019-22-10 resulted
from reports of cracking discovered in the left- and right-hand side
outboard chords of the station (STA) 663.75 frame fittings and failsafe
straps adjacent to the stringer S-18A straps and a determination that
the inspection area specified in AD 2019-20-02 needed to be expanded.
The FAA issued AD 2019-22-10 to address cracking in the STA 663.75
frame fitting outboard chords and failsafe straps adjacent to the
stringer S-18A straps, which could result in failure of a Principal
Structural Element (PSE) to sustain limit load. This condition could
adversely affect the structural integrity of the airplane and result in
loss of control of the airplane.
Actions Since AD 2019-22-10 Was Issued
Since the FAA issued AD 2019-22-10, it was determined by an
engineering analysis of the inspection reporting results and
metallurgical evaluation of the submitted frame fitting assemblies that
the initial inspection threshold for Model 737-900ER series airplanes,
and the repetitive inspection interval for all affected airplanes is
inadequate to address the cracking in a timely manner.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Multi-Operator Message MOM-MOM-20-0443-01B
(R1), dated June 2, 2020. This service information describes procedures
for repetitive detailed inspections for cracking of the left- and
right-hand side outboard chords of the STA 663.75 frame fittings and
failsafe straps around eight fasteners adjacent to the stringer S-18A
straps.
This proposed AD also requires Boeing Multi-Operator Message MOM-
MOM-19-0536-01B, dated September 30, 2019, which the Director of the
Federal Register approved for incorporation by reference as of October
3, 2019 (84 FR 52754, October 3, 2019).
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 agency 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 requires repetitive inspections for cracking of
the left- and right-hand side outboard chords of the STA 663.75 frame
fittings and failsafe straps around eight fasteners adjacent to the
stringer S-18A straps. This proposed AD also requires repair of all
cracking using a method approved by the FAA or The Boeing Company
Organization Designation Authorization (ODA). Accomplishing the initial
inspection required by paragraph (i) of this proposed AD would
terminate the inspections originally required by paragraph (g) of AD
2019-22-10, which are retained in this proposed AD (the associated
reporting specified in paragraph (h) of AD 2019-22-10 is also retained
in this proposed AD). This proposed AD would also require sending a
report of all results of the initial inspections specified in paragraph
(i) of this proposed AD to Boeing.
Although this proposed AD does not explicitly restate the
requirements of paragraphs (i), (j), and (k) of AD 2019-22-10, this
proposed AD would retain those requirements with certain revised
compliance times. Those requirements are referenced in Boeing Multi-
Operator Message MOM-MOM-20-0443-01B (R1), dated June 2, 2020, which,
in turn, is referenced in paragraphs (i) and (l) of this proposed AD.
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-2020-0789.
Explanation of New Compliance Times for Certain Configurations
For Boeing Model 737-600, -700, -700C, -800, and -900 series
airplanes having less than 22,600 total flight cycles and on which an
inspection specified in Boeing Multi-Operator Message MOM-MOM-19-0623-
01B, dated November 5, 2019, has been done; and for Boeing Model 737-
900ER series airplanes having less than 14,000 total flight cycles and
on which an inspection specified in Boeing Multi-Operator Message MOM-
MOM-19-0623-01B, dated November 5, 2019, has been done, the compliance
times specified in Boeing Multi-Operator Message MOM-MOM-20-0443-01B
(R1), dated June 2, 2020 (which will be required by this proposed AD),
are relieving as compared to the compliance times in Boeing Multi-
Operator Message MOM-MOM-19-0623-01B, dated November 5, 2019 (which is
required by AD 2019-22-10).
For example, for a Boeing Model 737-600 series airplane on which
the inspection was done and the airplane had accumulated 15,000 total
flight cycles, the next inspection required by AD 2019-22-10 would be
at 18,500 total flight cycles (i.e., 3,500 flight cycles after the
inspection as specified in
[[Page 55393]]
Boeing Multi-Operator Message MOM-MOM-19-0623-01B, dated November 5,
2019).
However, as specified in Boeing Multi-Operator Message MOM-MOM-20-
0443-01B (R1), dated June 2, 2020, the next inspection for that
airplane is prior to 22,600 total flight cycles or within 1,500 flight
cycles from the last inspection in accordance with MOM-MOM-19-0623-01B,
or within 30 days from the original issue date of MOM-MOM-20-0443-01B
(R1) (which would correspond to 30 days after the effective date of the
final rule for this proposed AD), whichever occurs latest.
In conclusion, if the inspection was done early, operators do not
have to do the next inspection at the 3,500 interval required by AD
2019-22-10 after this proposed AD is a final rule; instead operators
would then do the next inspection within the new compliance times
specified in Boeing Multi-Operator Message MOM-MOM-20-0443-01B R1),
dated June 2, 2020, for their configuration.
Interim Action
The FAA considers this proposed AD interim action. The inspection
reports that are required by this proposed AD will enable the
manufacturer to obtain better insight into the nature, cause, and
extent of the cracking, and eventually to develop final action to
address the unsafe condition. Once final action has been identified,
the FAA might consider further rulemaking.
Costs of Compliance
The FAA estimates that this proposed AD affects 1,911 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD:
Estimated Costs

The FAA has received no definitive data that would enable the
agency to provide cost estimates for the on-condition actions specified
in this proposed AD.
Paperwork Reduction Act
A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB control number. The control
number for the collection of information required by this proposed AD
is 2120-0056. The paperwork cost associated with this proposed AD has
been detailed in the Costs of Compliance section of this document and
includes time for reviewing instructions, as well as completing and
reviewing the collection of information. Therefore, all reporting
associated with this proposed AD is mandatory. Comments concerning the
accuracy of this burden and suggestions for reducing the burden should
be directed to Information Collection Clearance Officer, Federal
Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-
1524.
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.
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
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. The FAA amends Sec. 39.13 by removing Airworthiness Directive (AD)
2019-22-10, Amendment 39-19789 (84 FR 61533, November 13, 2019), and
adding the following new AD:
The Boeing Company: Docket No. FAA-2020-0789; Project Identifier AD-
2020-00849-T.
(a) Comments Due Date
The FAA must receive comments on this AD action by October 23,
2020.
[[Page 55394]]
(b) Affected ADs
This AD replaces AD 2019-22-10, Amendment 39-19789 (84 FR 61533,
November 13, 2019) (``AD 2019-22-10'').
(c) Applicability
This AD applies to all The Boeing Company Model 737-600, -700, -
700C, -800, -900, and -900ER series airplanes, certificated in any
category.
(d) Subject
Air Transport Association (ATA) of America Code 53, Fuselage.
(e) Unsafe Condition
This AD was prompted by reports of cracking discovered in the
station (STA) 663.75 frame fitting outboard chords and failsafe
straps adjacent to the stringer S-18A straps and a determination
that the initial inspection threshold for certain airplanes and the
repetitive inspection interval specified in AD 2019-22-10 are
inadequate to address the cracking in a timely manner. The FAA is
issuing this AD to address cracking in the STA 663.75 frame fitting
outboard chords and failsafe straps adjacent to the stringer S-18A
straps, which could result in failure of a Principal Structural
Element (PSE) to sustain limit load. This condition could adversely
affect the structural integrity of the airplane and result in loss
of control of the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Retained Inspection and Corrective Action With No Changes
This paragraph restates the requirements of paragraph (g) of AD
2019-22-10 with no changes. At the earlier of the times specified in
paragraphs (g)(1) and (2) of this AD: Do a detailed inspection for
cracking of the left- and right-hand side outboard chords of the STA
663.75 frame fittings and failsafe straps adjacent to the stringer
S-18A straps, in accordance with Boeing Multi-Operator Message MOM-
MOM-19-0536-01B, dated September 30, 2019. If any crack is found,
repair before further flight using a method approved in accordance
with the procedures specified in paragraph (n) of this AD. Repeat
the inspection thereafter at intervals not to exceed 3,500 flight
cycles until the initial inspection required by paragraph (i) of
this AD is done.
(1) Prior to the accumulation of 30,000 total flight cycles, or
within 7 days after October 3, 2019 (the effective date of AD 2019-
20-02, Amendment 39 19755 (84 FR 52754, October 3, 2019) (``AD 2019-
20-02'')), whichever occurs later.
(2) Prior to the accumulation of 22,600 total flight cycles, or
within 1,000 flight cycles after October 3, 2019 (the effective date
of AD 2019-20-02), whichever occurs later.
(h) Retained Reporting Requirement With No Changes
This paragraph restates the requirements of paragraph (h) of AD
2019-22-10, with no changes. At the applicable time specified in
paragraph (h)(1) or (2) of this AD, submit a report of all findings,
positive and negative, of the initial inspection required by
paragraph (g) of this AD. Submit the report in accordance with
Boeing Multi-Operator Message MOM-MOM-19-0536-01B, dated September
30, 2019.
(1) If the inspection was done on or after October 3, 3019 (the
effective date of AD 2019-20-02): Submit the report within 3 days
after the inspection.
(2) If the inspection was done before October 3, 2019 (the
effective date of AD 2019-20-02): Submit the report within 3 days
after October 3, 2019.
(i) Inspection and Corrective Action With Reduced Compliance Times
Except as specified in paragraph (j) of this AD: At the
applicable initial compliance time specified in Tables 1 and 2 of
``Ref I'' of Boeing Multi-Operator Message MOM-MOM-20-0443-01B (R1),
dated June 2, 2020, do a detailed inspection of the left- and right-
hand side outboard chords of the STA 663.75 frame fittings and
failsafe straps around eight fasteners adjacent to the stringer S-
18A straps, in accordance with Boeing Multi-Operator Message MOM-
MOM-20-0443-01B (R1), dated June 2, 2020. If any crack is found,
repair before further flight using a method approved in accordance
with the procedures specified in paragraph (n) of this AD. Repeat
the inspection thereafter at the applicable intervals specified in
Tables 1 and 2 of ``Ref I'' of Boeing Multi-Operator Message MOM-
MOM-20-0443-01B (R1), dated June 2, 2020. Accomplishing the initial
inspection required by this paragraph or an initial inspection
specified in Boeing Multi-Operator Message MOM-MOM-19-0623-01B,

paragraph (g) of this AD.
(j) Exceptions to Service Information Specifications
Where Boeing Multi-Operator Message MOM-MOM-20-0443-01B (R1),
dated June 2, 2020, uses the phrase ``the original issue date of

AD: Submit the report within 3 days after the effective date of this
AD.
(l) Special Flight Permit
Special flight permits may be issued in accordance with 14 CFR
21.197 and 21.199 to operate the airplane to a location where the
airplane can be repaired if any crack is found, provided the
Manager, Seattle ACO Branch, FAA, concurs with issuance of the
special flight permit. Send requests for concurrence by email to [email protected].
(m) Paperwork Reduction Act Burden Statement
