Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to adopt a new
airworthiness directive (AD) for certain
The Boeing Company Model 737–100,
–200, –200C, –300, –400, and –500
series airplanes. This proposed AD was
prompted by reports indicating that the
pitot heat switch is not always set to
ON, which could result in misleading
air data. This proposed AD would
require replacement of pitot anti-icing
system components, installation of a
junction box and wiring provisions,
repetitive testing of the anti-icing
system, and applicable on-condition
actions. We are proposing this AD to
address the unsafe condition on these
products.

comments. We specifically invite
comments on the overall regulatory,
economic, environmental, and energy
aspects of this NPRM. We will consider
all comments received by the closing
date and may amend this NPRM
because of those comments.
We will post all comments we
receive, without change, to https://
www.regulations.gov, including any
personal information you provide. We
will also post a report summarizing each
substantive verbal contact we receive
about this proposed AD.
Discussion
We have received reports indicating
that the pitot heat switch is not always
set to ON. The failure to activate the
manually activated pitot anti-icing
system likely resulted in misleading air
data that contributed to an accident and
three incidents involving Boeing Model
737 airplanes. This condition, if not
addressed, could result in the air data
sensors not being heated, which could
allow ice to form on the sensors and
cause erroneous air data. This erroneous
air data can lead to loss of crew
situational awareness and an inability to
maintain continued safe flight and
landing of the airplane.
Related Service Information Under 1
CFR Part 51
We reviewed Boeing Alert Service
Bulletin 737–30A1064, Revision 1,
dated October 18, 2017. The service
FAA’s Determination
information describes procedures for
replacement and repetitive testing of the
P5–9 window and pitot heat module,
changing the anti-icing system to
automatically supply power to heat the
air data sensors. If flight crews fail to
activate it manually, the anti-icing
system will come on automatically after
engine start.
We also reviewed the following
concurrent service information.
• Boeing Service Bulletin 737–30–
1067, Revision 1, dated May 4, 2017.
This service information describes
procedures for installing a new J18
junction box to change the anti-icing
system.
• Boeing Service Bulletin 737–30–
1068, Revision 1, dated May 4, 2017.
This service information describes
procedures for installing wiring
provisions to the anti-icing system.
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.
We are proposing this AD because we
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 would require
accomplishment of the actions
identified as ‘‘RC’’ (required for
compliance) in the Accomplishment
Instructions of Boeing Alert Service
Bulletin 737–30A1064, Revision 1,
dated October 18, 2017, described
previously, except for any differences
identified as exceptions in the
regulatory text of this proposed AD.
This proposed AD would also require
accomplishing the actions specified in
Boeing Service Bulletin 737–30–1067,
Revision 1, dated May 4, 2017; and
Boeing Service Bulletin 737–30–1068,
Revision 1, dated May 4, 2017,
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–2018–
0961.
Minimum Equipment List (MEL)
Provision
Operators are required by 14 CFR part
91 to have an MEL to operate with
inoperable equipment. Paragraph (l) of
this proposed AD allows for the
operation of the airplane even if the
modified air data probe heat (ADPH)
system is inoperable, so long as the
operator’s MEL has a provision to allow
for this inoperability.
Costs of Compliance

affects 296 airplanes of U.S. registry. We
estimate the following costs to comply
with this proposed AD:

Regulatory Findings
We 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 this proposed regulation:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866,
(2) Is not a ‘‘significant rule’’ under
the 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.

Discussion
We received several reports of HCF
cracks found in the fuel nozzle supply
manifold tube at the braze joint interface
on PW PW4158 turbofan engines
identified with suffix–3 on the Engine
Data Plate, and equipped with the Talon
IIB combustor chamber. The root cause
of the cracks in the braze joint was
attributed to thermal mechanical fatigue
due to high thermal gradients on
engines equipped with the Talon IIB
combustor chamber. This condition, if
not addressed, could result in engine
fire, damage to the engine, and damage
to the airplane.
Related Service Information Under 1
CFR Part 51

Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for
certain The Boeing Company Model 737-100, -200, -200C, -300, -400, and
-500 series airplanes. This proposed AD was prompted by reports
indicating that the pitot heat switch is not always set to ON, which
could result in misleading air data. This proposed AD would require
replacement of pitot anti-icing system components, installation of a
junction box and wiring provisions, repetitive testing of the anti-
icing system, and applicable on-condition actions. We are proposing
this AD to address the unsafe condition on these products.

Discussion
We have received reports indicating that the pitot heat switch is
not always set to ON. The failure to activate the manually activated
pitot anti-icing system likely resulted in misleading air data that
contributed to an accident and three incidents involving Boeing Model
737 airplanes. This condition, if not addressed, could result in the
air data sensors not being heated, which could allow ice to form on the
sensors and cause erroneous air data. This erroneous air data can lead
to loss of crew situational awareness and an inability to maintain
continued safe flight and landing of the airplane.
Related Service Information Under 1 CFR Part 51
We reviewed Boeing Alert Service Bulletin 737-30A1064, Revision 1,
dated October 18, 2017. The service information describes procedures
for replacement and repetitive testing of the P5-9 window and pitot
heat module, changing the anti-icing system to automatically supply
power to heat the air data sensors. If flight crews fail to activate it
manually, the anti-icing system will come on automatically after engine
start.
We also reviewed the following concurrent service information.
Boeing Service Bulletin 737-30-1067, Revision 1, dated May
4, 2017. This service information describes procedures for installing a
new J18 junction box to change the anti-icing system.
Boeing Service Bulletin 737-30-1068, Revision 1, dated May
4, 2017. This service information describes procedures for installing
wiring provisions to the anti-icing system.
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.
Minimum Equipment List (MEL) Provision
Operators are required by 14 CFR part 91 to have an MEL to operate
with inoperable equipment. Paragraph (l) of this proposed AD allows for
the operation of the airplane even if the modified air data probe heat
(ADPH) system is inoperable, so long as the operator's MEL has a
provision to allow for this inoperability.
FAA's Determination
We are proposing this AD because we 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 would require accomplishment of the actions
identified as ``RC'' (required for compliance) in the Accomplishment
Instructions of Boeing Alert Service Bulletin 737-30A1064, Revision 1,
dated October 18, 2017, described previously, except for any
differences identified as exceptions in the regulatory text of this
proposed AD.
This proposed AD would also require accomplishing the actions
specified in Boeing Service Bulletin 737-30-1067, Revision 1, dated May
4, 2017; and Boeing Service Bulletin 737-30-1068, Revision 1, dated May
4, 2017, 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-2018-0961.
Costs of Compliance
We estimate that this proposed AD affects 296 airplanes of U.S.
registry. We estimate the following costs to comply with 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.
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.
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
[[Page 58198]]
category airplanes to the Director of the System Oversight Division.
Regulatory Findings
We 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 this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under the 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.

(m) 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 (n)(2) 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 Commercial Airplanes Organization
Designation Authorization (ODA) that has been authorized by the

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) For service information that contains steps that are labeled
as RC, the provisions of paragraphs (m)(4)(i) and (m)(4)(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.
