Administration (FAA), DOT.
ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for certain
Honeywell International Inc.
(Honeywell) AS907–1–1A turbofan
engines. This AD was prompted by
reports of loss of power due to failure
of the second stage low-pressure turbine
(LPT2) blade. This AD requires a onetime inspection of the LPT2 blades and,
if the blades fail the inspection, the
replacement of the blades with a part
eligible for installation. We are issuing
this AD to address the unsafe condition
on these products.
DATES: This AD is effective November 9,
2017.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of November 9, 2017.

this AD to prevent failure of the LPT2
blades, failure of one or more engines,
and loss of the airplane.
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain Honeywell
International Inc. (Honeywell) AS907–
1–1A turbofan engines. The NPRM
published in the Federal Register on
June 20, 2017 (82 FR 28028). The NPRM
was prompted by reports of loss of
power due to failure of the second stage
LPT2 blade from high-cycle fatigue in
the blade’s dovetail region. The NPRM
proposed to require a one-time
inspection of the LPT2 blades and, if the
blades fail the inspection, the
replacement of the blades with a part
We reviewed the relevant data and
determined that air safety and the
public interest require adopting this
final rule as proposed except for 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.
Comments
We gave the public the opportunity to
participate in developing this final rule.
We received no comments on the NPRM
or on the determination of the cost to
the public.
Conclusion
Related Service Information Under 1
CFR Part 51
We reviewed Honeywell Service
Bulletin (SB) AS907–72–9067, Revision
1, dated March 20, 2017. This SB
describes procedures for inspecting the
LPT2 blades. 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.
Other Related Service Information
We reviewed Honeywell SB AS907–
72–9067, Revision 0, dated December
12, 2016, which also describes
procedures for inspecting the LPT2
blades. We also reviewed the Honeywell
Light Maintenance Manual, AS907–1–
1A, 72–00–00, Section 72–05–12, dated
May 25, 2016, and Section 72–55–03,
dated September 27, 2011, which
provide additional guidance for
performing borescope inspections.

ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for The
Boeing Company Model 707 airplanes
equipped with a main cargo door
(MCD). This AD was prompted by
analysis of the cam support assemblies
of the MCD that indicated the repetitive
high frequency eddy current (HFEC)
inspections required by the existing
maintenance program are not adequate
to detect cracks before two adjacent cam
support assemblies of the MCD could
fail. This AD requires repetitive
ultrasonic inspections for cracking of
the cam support assemblies of the MCD,
and replacement if necessary. We are
issuing this AD to address the unsafe
condition on these products.
DATES: This AD is effective November 9,
2017.

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 all The Boeing Company Model
707 airplanes. The NPRM published in
the Federal Register on October 4, 2016
(81 FR 68376) (‘‘the NPRM’’). The
NPRM was prompted by analysis of the
cam support assemblies of the MCD that
indicated the repetitive HFEC
inspections required by the existing
maintenance program are not adequate
to detect cracks before two adjacent cam
support assemblies of the MCD could
fail. The NPRM proposed to require
repetitive ultrasonic inspections for
cracking of the cam support assemblies
of the MCD, and replacement if
necessary. We are issuing this AD to
detect and correct cracking of the cam
support assemblies of the MCD. Such
cracking could result in reduced
structural integrity of the MCD and
consequent rapid decompression of the
airplane.
Comments
We gave the public the opportunity to
participate in developing this final rule.
The following presents the comments
received on the NPRM and the FAA’s
response to each comment.
Request To Revise Applicability
Boeing stated that Boeing 707 Alert
Service Bulletin A3542, dated February
12, 2016, affects only Boeing factory and
Boeing-converted freighters, but the
PO 00000
Frm 00014
Fmt 4700
Sfmt 4700
proposed AD extends the applicability
to all Model 707 airplanes, including
the ones that have been converted by
non-Boeing supplemental type
certificates (STCs).
We infer the commenter is requesting
that the actions of the service
information only be required for Model
707 airplanes identified in the
Effectivity paragraph of Boeing 707
Alert Service Bulletin A3542, dated
February 12, 2016. We agree that the
applicability of the proposed AD should
not include Model 707 airplanes that do
not have an MCD. However, we disagree
that the AD applicability should be
limited to the airplanes identified in the
Effectivity paragraph of Boeing 707
Alert Service Bulletin A3542, dated
February 12, 2016, which only identifies
Boeing factory and Boeing-converted
freighters. The cam support assemblies
having the affected part number could
be installed at original aircraft
manufacture, or during passenger-tofreighter modification. We expect that
the actions specified in Boeing 707 Alert
Service Bulletin A3542, dated February
12, 2016, can be accomplished on
airplanes that are not identified in that
service information. However, if an
operator with a Model 707 freighter that
is not a part of Boeing type design
cannot accomplish the required actions
in the service information, or prefers to
use different service information that is
specific to their design, approval of an
alternative method of compliance
(AMOC) can be requested in accordance
with paragraph (j) of this AD. We
revised this AD to limit the applicability
to Model 707 airplanes equipped with
an MCD.
Request To Supersede AD 80–08–10 R1,
Amendment 39–3830 (45 FR 46343, July
10, 1980) (‘‘AD 80–08–10 R1’’)
Boeing requested that we revise the
NPRM to supersede AD 80–08–10 R1.
Boeing stated that AD 80–08–10 R1
mandates HFEC inspections of MCD
cam support assemblies having part
numbers (P/Ns) 69–23588–1 and 69–
23588–2, as specified in Boeing Service
Bulletin 707–A3387. Boeing explained
that the NPRM is adding cam support
assemblies having P/Ns 69–23588–1 and
69–23588–2 to the list in Boeing 707
Alert Service Bulletin A3542, dated
February 12, 2016. Boeing asserted that
the addition of these components to the
list of affected parts would mean that
the operators have to perform HFEC
inspections of cam support assemblies
having P/Ns 69–23588–1 and 69–
23588–2, as specified in AD 80–08–10
R1, and perform ultrasonic inspections
of the same components, as specified in
the proposed AD. Boeing explained that

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Honeywell International Inc. (Honeywell) AS907-1-1A turbofan engines.
This AD was prompted by reports of loss of power due to failure of the
second stage low-pressure turbine (LPT2) blade. This AD requires a one-
time inspection of the LPT2 blades and, if the blades fail the
inspection, the replacement of the blades with a part eligible for
installation. We are issuing this AD to address the unsafe condition on
these products.
DATES: This AD is effective November 9, 2017.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of November 9,
2017.

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 Honeywell
International Inc. (Honeywell) AS907-1-1A turbofan engines. The NPRM
published in the Federal Register on June 20, 2017 (82 FR 28028). The
NPRM was prompted by reports of loss of power due to failure of the
second stage LPT2 blade from high-cycle fatigue in the blade's dovetail
region. The NPRM proposed to require a one-time inspection of the LPT2
blades and, if the blades fail the inspection, the replacement of the
blades with a part eligible for installation. We are issuing this AD to
prevent failure of the LPT2 blades, failure of one or more engines, and
loss of the airplane.
Comments
We gave the public the opportunity to participate in developing
this final rule. We received no comments on the NPRM or on the
determination of the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting this final rule as proposed except
for 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.
Related Service Information Under 1 CFR Part 51
We reviewed Honeywell Service Bulletin (SB) AS907-72-9067, Revision
1, dated March 20, 2017. This SB describes procedures for inspecting
the LPT2 blades. 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.
Other Related Service Information
We reviewed Honeywell SB AS907-72-9067, Revision 0, dated December
12, 2016, which also describes procedures for inspecting the LPT2
blades. We also reviewed the Honeywell Light Maintenance Manual, AS907-
1-1A, 72-00-00, Section 72-05-12, dated May 25, 2016, and Section 72-
55-03, dated September 27, 2011, which provide additional guidance for
performing borescope inspections.
Costs of Compliance
We estimate that this AD affects 40 engines installed on 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

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 AD is 2120-
0056. The paperwork cost associated with this 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 AD is mandatory. Comments concerning the accuracy of this burden
and suggestions for reducing the burden should be directed to the FAA
at 800 Independence Ave., SW., Washington, DC 20591. ATTN: Information
Collection Clearance Officer, AES-200.
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.
[[Page 46381]]
This 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 engines, propellers, and
associated appliances to the Manager, Engine and Propeller Standards
Branch, Policy and Innovation Division.
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 to the extent
that it justifies making a regulatory distinction, 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.
