Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
The FAA proposes to
supersede Airworthiness Directive (AD)
2016–07–28, which applies to all The
Boeing Company Model DC–9–81 (MD–
81), DC–9–82 (MD–82), DC–9–83 (MD–
83), and DC–9–87 (MD–87) airplanes,
and Model MD–88 airplanes. AD 2016–
07–28 requires repetitive eddy current
high frequency (ETHF) inspections for
any cracking in the left and right side
center wing lower skin, and repair if any
crack is found. Since the FAA issued
AD 2016–07–28, the FAA has
determined it is necessary to expand the
inspection area to include adjacent
stringers with similar stress levels and
to perform an inspection with increased
sensitivity for crack detection. This
proposed AD would retain certain
requirements of AD 2016–07–28,
expand the inspection area, and require
new 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 March 30, 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 2016–07–28,
Amendment 39–18473 (81 FR 21253,
April 11, 2016) (‘‘AD 2016–07–28’’), for
all The Boeing Company Model DC–9–
81 (MD–81), DC–9–82 (MD–82), DC–9–
83 (MD–83), and DC–9–87 (MD–87)
airplanes, and Model MD–88 airplanes.
AD 2016–07–28 requires repetitive
ETHF inspections for any cracking in
the left and right side center wing lower
skin, and repair if any crack is found.
AD 2016–07–28 resulted from reports of
cracking at certain stringers, associated
end fittings, and skins in the center
wing fuel tank where the stringers meet
the end fittings. The FAA issued AD
2016–07–28 to detect and correct
cracking in the center wing lower skin.
Such cracking could cause structural
failure of the wings.
Actions Since AD 2016–07–28 Was
Issued
Since the FAA issued AD 2016–07–
28, there have been additional reports of
cracks at certain stringers, including one
at stringer S–13, which was not
addressed in AD 2016–07–28. The FAA
has determined it is necessary to expand
the inspection area to include adjacent
stringers with similar stress levels and
to perform a new inspection with
increased sensitivity for crack detection
in the area (eddy current low frequency
(ETLF) inspection). This proposed AD
would retain certain requirements of AD
2016–07–28, expand the inspection area
and require new inspections.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Boeing Alert
Service Bulletin MD80–57A244,
Revision 1, dated October 1, 2019. This
service information describes
procedures for a general visual
inspection (GVI) for existing repairs;
repetitive ETLF inspections of the left
and right side fastener holes common to
stringers 11 through 22 and the forward
and aft skins for any crack; repetitive
ETHF inspections of the lower skin at
stringers 18 through 20 for any crack; an
ETHF inspection of the left side and
right side center wing lower skin for any
crack; and applicable on-condition
actions. On-condition actions include
repair and an internal GVI for any
cracks in stringers 11 through 22
between Xcw=0.0 and Xcw=20.0. 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
2016–07–28, this proposed AD would
retain some of the requirements of AD
2016–07–28. 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 as ‘‘RC’’ (required for
compliance) in the Accomplishment
Instructions of Boeing Alert Service
Bulletin MD80–57A244, Revision 1,
dated October 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–2020–
0096.
Costs of Compliance
The FAA estimates that this proposed
AD affects 288 airplanes of U.S. registry.
The FAA estimates the following costs

Federal Register / Vol. 85, No. 30 / Thursday, February 13, 2020 / Proposed Rules
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.

section, the FAA is charged with
prescribing regulations to assign the use
of airspace necessary to ensure the
safety of aircraft and the efficient use of
airspace. This regulation is within the
scope of that authority as it would
amend Class D and E airspace in
Jacksonville NAS, FL and Mayport, FL,
to support IFR operations in the area.
Comments Invited
Interested persons are invited to
comment on this proposed rulemaking
by submitting such written data, views,
or arguments, as they may desire.

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)
2016-07-28, which applies to all The Boeing Company Model DC-9-81 (MD-
81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) airplanes,
and Model MD-88 airplanes. AD 2016-07-28 requires repetitive eddy
current high frequency (ETHF) inspections for any cracking in the left
and right side center wing lower skin, and repair if any crack is
found. Since the FAA issued AD 2016-07-28, the FAA has determined it is
necessary to expand the inspection area to include adjacent stringers
with similar stress levels and to perform an inspection with increased
sensitivity for crack detection. This proposed AD would retain certain
requirements of AD 2016-07-28, expand the inspection area, and require
new 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 March 30,
2020.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion
The FAA issued AD 2016-07-28, Amendment 39-18473 (81 FR 21253,
April 11, 2016) (``AD 2016-07-28''), for all The Boeing Company Model
DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87)
airplanes, and Model MD-88 airplanes. AD 2016-07-28 requires repetitive
ETHF inspections for any cracking in the left and right side center
wing lower skin, and repair if any crack is found. AD 2016-07-28
resulted from reports of cracking at certain stringers, associated end
fittings, and skins in the center wing fuel tank where the stringers
meet the end fittings. The FAA issued AD 2016-07-28 to detect and
correct cracking in the center wing lower skin. Such cracking could
cause structural failure of the wings.
Actions Since AD 2016-07-28 Was Issued
Since the FAA issued AD 2016-07-28, there have been additional
reports of cracks at certain stringers, including one at stringer S-13,
which was not addressed in AD 2016-07-28. The FAA has determined it is
necessary to expand the inspection area to include adjacent stringers
with similar stress levels and to perform a new inspection with
increased sensitivity for crack detection in the area (eddy current low
frequency (ETLF) inspection). This proposed AD would retain certain
requirements of AD 2016-07-28, expand the inspection area and require
new inspections.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Alert Service Bulletin MD80-57A244,
Revision 1, dated October 1, 2019. This service information describes
procedures for a general visual inspection (GVI) for existing repairs;
repetitive ETLF inspections of the left and right side fastener holes
common to stringers 11 through 22 and the forward and aft skins for any
crack; repetitive ETHF inspections of the lower skin at stringers 18
through 20 for any crack; an ETHF inspection of the left side and right
side center wing lower skin for any crack; and applicable on-condition
actions. On-condition actions include repair and an internal GVI for
any cracks in stringers 11 through 22 between Xcw=0.0 and Xcw=20.0.
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 2016-07-28, this proposed AD would retain some of
the requirements of AD 2016-07-28. 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 as ``RC''
(required for compliance) in the Accomplishment Instructions of Boeing
Alert Service Bulletin MD80-57A244, Revision 1, dated October 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-2020-0096.
Costs of Compliance
The FAA estimates that this proposed AD affects 288 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.

----------------------------------------------------------------------------------------------------------------
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.

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

unless already done.
(g) Required Actions
Except as specified in paragraph (h) of this AD: At the
applicable times specified in paragraph 1.E., ``Compliance,'' of
Boeing Alert Service Bulletin MD80-57A244, Revision 1, dated October
1, 2019, do all applicable actions identified as ``RC'' (required
for compliance) in, and in accordance with, the Accomplishment
Instructions of Boeing Alert Service Bulletin MD80-57A244, Revision
1, dated October 1, 2019.
Note 1 to paragraph (g) of this AD: Boeing Alert Service
Bulletin MD80-57A244, Revision 1, dated October 1, 2019, refers to
Drawing SN09570007 for certain inspection sequences. If the pages of
Drawing SN09570007 are illegible, guidance can be found in Boeing
Multi Operator Message MOM-MOM-19-0549-01B, dated October 4, 2019.
(h) Exception to Service Information Specifications
Where Boeing Alert Service Bulletin MD80-57A244, Revision 1,
dated October 1, 2019, specifies contacting Boeing for repair
instructions or for alternative inspections: This AD requires doing
the repair, or doing the alternative inspections and applicable on-
condition actions before further flight using a method approved in
accordance with the procedures specified in paragraph (i) of this
AD.
(i) Alternative Methods of Compliance (AMOCs)
(1) The Manager, Los Angeles ACO Branch, FAA, has the authority
to approve AMOCs for this AD, if requested using the procedures
found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your
request to your principal inspector or local Flight Standards
District Office, as appropriate. If sending information directly to
the manager of the certification office, send it to the attention of
the person identified in paragraph (j)(1) of this AD. Information
may be emailed to: [email protected].
(2) Before using any approved AMOC, notify your appropriate
principal inspector, or lacking a principal inspector, the manager
of the local flight standards district office/certificate holding
district office.
(3) An AMOC that provides an acceptable level of safety may be
used for any repair, modification, or alteration required by this AD
if it is approved by The Boeing Company Organization Designation
Authorization (ODA) that has been authorized by the Manager, Los
Angeles ACO Branch, FAA, to make those findings. To be approved, the
repair method, modification deviation, or alteration deviation must
meet the certification basis of the airplane, and the approval must
specifically refer to this AD.
(4) AMOCs approved previously for AD 2016-07-28 are not approved
as AMOCs for this AD.
(5) For service information that contains steps that are labeled
as Required for Compliance (RC), the provisions of paragraphs
(i)(5)(i) and (ii) of this AD apply.
(i) The steps labeled as RC, including substeps under an RC step
and any figures identified in an RC step, must be done to comply
with the AD. If a step or substep is labeled ``RC Exempt,'' then the
RC requirement is removed from that step or substep. An AMOC is
required for any deviations to RC steps, including substeps and
identified figures.
(ii) Steps not labeled as RC may be deviated from using accepted
methods in accordance with the operator's maintenance or inspection
program without obtaining approval of an AMOC, provided the RC
steps, including substeps and identified figures, can still be done
as specified, and the airplane can be put back in an airworthy
condition.
