FOR FURTHER INFORMATION CONTACT:
We are adopting a new
airworthiness directive (AD) for certain
The Boeing Company Model 767–200
and –300 series airplanes. This AD was
prompted by an evaluation by the

indicating that the aft pressure bulkhead
is subject to widespread fatigue damage
(WFD). This AD requires replacing the
aft pressure bulkhead with a new,
improved aft pressure bulkhead, and
doing related investigative and
corrective actions if necessary. We are
issuing this AD to prevent the unsafe
condition on these products.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain The Boeing Company
Model 767–200 and –300 series
airplanes. The NPRM published in the
Federal Register on February 22, 2016
(81 FR 8668) (‘‘the NPRM’’). The NPRM
was prompted by an evaluation by the
DAH indicating that the aft pressure
bulkhead at Station 1582 is subject to
WFD. The NPRM proposed to require
replacing the aft pressure bulkhead with
a new, improved aft pressure bulkhead,
and doing related investigative and
corrective actions if necessary. We are
issuing this AD to prevent fatigue
cracking in the radial web lap splices of
the aft pressure bulkhead. Such cracking
could result in rapid decompression and
consequent reduced structural integrity
of the airplane.
PO 00000
Frm 00001
Fmt 4700
Sfmt 4700
We gave the public the opportunity to
participate in developing this AD. We
have considered the comments received.
Boeing and United Airlines supported
the NPRM.
Aviation Partners Boeing stated that
accomplishing the supplemental type
certificate (STC) ST01920SE does not
affect compliance with the actions
specified in the NPRM.
We agree with the commenter. We
have redesignated paragraph (c) of the
proposed AD as (c)(1) and added
paragraph (c)(2) to this AD to state that
installation of STC ST01920SE does not
affect the ability to accomplish the
actions required by this final rule.
Therefore, for airplanes on which STC
ST01920SE is installed, a ‘‘change in
product’’ alternative method of
compliance (AMOC) approval request is
not necessary to comply with the
requirements of 14 CFR 39.17.
Changes To This AD
We have reviewed Boeing Alert
Service Bulletin 767–53A0267, Revision
1, dated August 4, 2016, and there are
no substantial changes. Therefore, we
have included Boeing Alert Service
Bulletin 767–53A0267, Revision 1,
dated August 4, 2016, in paragraphs (c),
(g), (h), and (i) of this AD. We have also
provided credit in paragraph (j) of this
AD for actions done prior to the
effective date of this AD using Boeing
Alert Service Bulletin 767–53A0267,
dated August 13, 2015.
We have also revised paragraph (g) of
this AD to clarify certain terminating
actions.
Conclusion
We reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting this AD
with the changes described previously
and minor editorial changes. We have
determined that these minor changes:
• Are consistent with the intent that
was proposed in the NPRM for
correcting the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.
We also determined that these
changes will not increase the economic

Related Service Information Under 1
CFR part 51
We reviewed Boeing Alert Service
Bulletin 767–53A0267, Revision 1,
dated August 4, 2016. The service
information describes procedures for
replacing the aft pressure bulkhead at
Station 1582 of Section 48 with a new,
improved aft pressure bulkhead,
including all applicable related
investigative and corrective 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.
Costs of Compliance
We estimate that this AD affects 86
airplanes of U.S. registry.
We estimate the following costs to
comply with this AD:

1,541 work-hours × $85 per hour = $130,985 .......................
We have received no definitive data

corrective actions specified in this AD.
sradovich on DSK3GMQ082PROD with 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.
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
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),
(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

not affect the ability to accomplish the
actions required by this AD. Therefore, for
airplanes on which STC ST01920SE is
installed, a ‘‘change in product’’ alternative
method of compliance (AMOC) approval
request is not necessary to comply with the
requirements of 14 CFR 39.17.
(d) Subject
Air Transport Association (ATA) of
America Code 53, Fuselage.
(e) Unsafe Condition
This AD was prompted by an evaluation by
the design approval holder (DAH) indicating
that the aft pressure bulkhead at Station 1582
is subject to widespread fatigue damage
(WFD). We are issuing this AD to prevent
fatigue cracking in the radial web lap splices
of the aft pressure bulkhead. Such cracking
could result in rapid decompression and
consequent reduced structural integrity of the

later, but not earlier than 37,500 total
accumulated flight cycles: Replace the aft
pressure bulkhead at Station 1582 of Section
48 with a new, improved aft pressure
bulkhead, and perform all applicable related
investigative and corrective actions, in
accordance with the Accomplishment
Instructions of Boeing Alert Service Bulletin
767–53A0267, Revision 1, dated August 4,
2016; except as required by paragraph (h) of
this AD. Do all applicable related
investigative and corrective actions before
further flight. Accomplishing the
replacement in this paragraph terminates all
requirements of the ADs identified in
paragraphs (g)(1), (g)(2), and (g)(3) of this AD.
(1) AD 2004–05–16, Amendment 39–13511
(69 FR 10917, March 9, 2004).
(2) AD 2004–14–19, Amendment 39–13728
(69 FR 42549, July 16, 2004).
(3) AD 2009–06–19, Amendment 39–15856

(j) Credit for Previous Actions
This paragraph provides credit for the
actions required by paragraphs (g) and (h) of
this AD, if those actions were performed
before the effective date of this AD using
Boeing Alert Service Bulletin 767–53A0267,
dated August 13, 2015; which is not
incorporated by reference in this AD.
(k) Alternative Methods of Compliance
(AMOCs)
(1) The Manager, Seattle Aircraft
Certification Office (ACO), 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

attention of the person identified in
paragraph (l) of this AD. Information may be
emailed to: 9–ANM-Seattle-ACO-AMOCRequests@faa.gov.
(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
Commercial Airplanes Organization
Designation Authorization (ODA) that has
been authorized by the Manager, Seattle
ACO, 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) Except as required by paragraph (h) of
this AD: For service information that
contains steps that are labeled as Required
for Compliance (RC), the provisions of

Jkt 241001
sub-step. 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,

necessary. This new AD requires
repetitive detailed inspections, and
repair if necessary. This AD was
prompted by new reports of cracking
found in the wing rear spar and
technical analysis results, which
confirmed that the crack initiation and
propagation are due to fatigue, with no
indication of any other crack initiation
mechanism (e.g., stress corrosion). We
are issuing this AD to address the unsafe

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to certain The Boeing Company
Model 767-200 and -300 series airplanes. The NPRM published in the
Federal Register on February 22, 2016 (81 FR 8668) (``the NPRM''). The
NPRM was prompted by an evaluation by the DAH indicating that the aft
pressure bulkhead at Station 1582 is subject to WFD. The NPRM proposed
to require replacing the aft pressure bulkhead with a new, improved aft
pressure bulkhead, and doing related investigative and corrective
actions if necessary. We are issuing this AD to prevent fatigue
cracking in the radial web lap splices of the aft pressure bulkhead.
Such cracking could result in rapid decompression and consequent
reduced structural integrity of the airplane.
Comments
We gave the public the opportunity to participate in developing
this AD. We have considered the comments received. Boeing and United
Airlines supported the NPRM.
Effect of Winglets on Accomplishment of the Proposed Actions
Aviation Partners Boeing stated that accomplishing the supplemental
type certificate (STC) ST01920SE does not affect compliance with the
actions specified in the NPRM.
We agree with the commenter. We have redesignated paragraph (c) of
the proposed AD as (c)(1) and added paragraph (c)(2) to this AD to
state that installation of STC ST01920SE does not affect the ability to
accomplish the actions required by this final rule. Therefore, for
airplanes on which STC ST01920SE is installed, a ``change in product''
alternative method of compliance (AMOC) approval request is not
necessary to comply with the requirements of 14 CFR 39.17.
Changes To This AD
We have reviewed Boeing Alert Service Bulletin 767-53A0267,
Revision 1, dated August 4, 2016, and there are no substantial changes.
Therefore, we have included Boeing Alert Service Bulletin 767-53A0267,
Revision 1, dated August 4, 2016, in paragraphs (c), (g), (h), and (i)
of this AD. We have also provided credit in paragraph (j) of this AD
for actions done prior to the effective date of this AD using Boeing
Alert Service Bulletin 767-53A0267, dated August 13, 2015.
We have also revised paragraph (g) of this AD to clarify certain
terminating actions.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this AD with the changes described previously and minor editorial
changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
We also determined that these changes will not increase the
economic
[[Page 6]]
burden on any operator or increase the scope of this AD.
Related Service Information Under 1 CFR part 51
We reviewed Boeing Alert Service Bulletin 767-53A0267, Revision 1,
dated August 4, 2016. The service information describes procedures for
replacing the aft pressure bulkhead at Station 1582 of Section 48 with
a new, improved aft pressure bulkhead, including all applicable related
investigative and corrective 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.
Costs of Compliance
We estimate that this AD affects 86 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Replacement........................ 1,541 work-hours x $85 per $646,889 $777,874 $66,897,164
hour = $130,985.
----------------------------------------------------------------------------------------------------------------
We have received no definitive data that enables us to provide cost
estimates for the on-condition investigative and corrective actions
specified in this 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
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
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),
(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.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 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 adding the following new airworthiness
directive (AD):
2016-25-07 The Boeing Company: Amendment 39-18733; Docket No. FAA-
2016-3698; Directorate Identifier 2015-NM-138-AD.
(a) Effective Date
This AD is effective February 7, 2017.
(b) Affected ADs
This AD affects the ADs specified in paragraphs (b)(1), (b)(2),
and (b)(3) of this AD.
(1) AD 2004-05-16, Amendment 39-13511 (69 FR 10917, March 9,
2004).
(2) AD 2004-14-19, Amendment 39-13728 (69 FR 42549, July 16,
2004).
(3) AD 2009-06-19, Amendment 39-15856 (74 FR 12243, March 24,
2009).
(c) Applicability
(1) This AD applies to The Boeing Company Model 767-200 and -300
series airplanes, certificated in any category, as identified in
Boeing Alert Service Bulletin 767-53A0267, Revision 1, dated August
4, 2016.
(2) Installation of Supplemental Type Certificate (STC)
ST01920SE (https://rgl.faa.gov/Regulatory_and_Guidance_Library/rgSTC.nsf/0/38B606833BBD98B386257FAA00602538?OpenDocument&Highlight=st01920se)
does not affect the ability to accomplish the actions required by
this AD. Therefore, for airplanes on which STC ST01920SE is
installed, a ``change in product'' alternative method of compliance
(AMOC) approval request is not necessary to comply with the
requirements of 14 CFR 39.17.
(d) Subject
Air Transport Association (ATA) of America Code 53, Fuselage.
(e) Unsafe Condition
This AD was prompted by an evaluation by the design approval
holder (DAH) indicating that the aft pressure bulkhead at Station
1582 is subject to widespread fatigue damage (WFD). We are issuing
this AD to prevent fatigue cracking in the radial web lap splices of
the aft pressure bulkhead. Such cracking could result in rapid
decompression and consequent reduced structural integrity of the
airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Replacement, Related Investigative and Corrective Actions, and
Terminating Actions
Before the accumulation of 60,000 total flight cycles, or within
36 months after the effective date of this AD, whichever occurs
later, but not earlier than 37,500 total accumulated flight cycles:
Replace the aft pressure bulkhead at Station 1582 of Section 48 with
a new, improved aft pressure bulkhead, and perform all applicable
related investigative and corrective actions, in accordance with the
Accomplishment Instructions of Boeing Alert Service Bulletin 767-
53A0267, Revision 1, dated August 4, 2016; except as required by
paragraph (h) of this AD. Do all applicable related investigative
and corrective actions before further flight. Accomplishing the
replacement in this paragraph terminates all requirements of the ADs
identified in paragraphs (g)(1), (g)(2), and (g)(3) of this AD.
(1) AD 2004-05-16, Amendment 39-13511 (69 FR 10917, March 9,
2004).
(2) AD 2004-14-19, Amendment 39-13728 (69 FR 42549, July 16,
2004).
(3) AD 2009-06-19, Amendment 39-15856 (74 FR 12243, March 24,
2009).
[[Page 7]]
(h) Corrective Actions
If any defect (e.g., rifling, gouging, nicks, or burrs, or
excessive surface roughness) is found in any fastener hole (other
than normally produced during a typical reaming operation), during
accomplishment of any inspection (related investigative actions)
required by this AD, and Boeing Alert Service Bulletin 767-53A0267,
Revision 1, dated August 4, 2016, specifies to contact Boeing for
repair instructions: Before further flight, repair in accordance
with the procedures specified in paragraph (k) of this AD.
(i) Exception to the Service Information
Where Boeing Alert Service Bulletin 767-53A0267, Revision 1,
dated August 4, 2016, specifies a compliance time ``after the
original issue date of this service bulletin,'' this AD requires
compliance within the specified time after the effective date of
this AD.
(j) Credit for Previous Actions
This paragraph provides credit for the actions required by
paragraphs (g) and (h) of this AD, if those actions were performed
before the effective date of this AD using Boeing Alert Service
Bulletin 767-53A0267, dated August 13, 2015; which is not
incorporated by reference in this AD.
(k) Alternative Methods of Compliance (AMOCs)
(1) The Manager, Seattle Aircraft Certification Office (ACO),
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 ACO, send it to the
attention of the person identified in paragraph (l) of this AD.
Information may be emailed to: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov.
(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 Commercial Airplanes Organization
Designation Authorization (ODA) that has been authorized by the
Manager, Seattle ACO, 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) Except as required by paragraph (h) of this AD: For service
information that contains steps that are labeled as Required for
Compliance (RC), the provisions of paragraphs (k)(4)(i) and
(k)(4)(ii) 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 sub-step is labeled ``RC Exempt,'' then
the RC requirement is removed from that step or sub-step. 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.
