SUPPLEMENTARY INFORMATION:
Background
The FAA has received reports
indicating that the pitot heat switch is
not always set to ON, which could
result in misleading air data. 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
could ultimately result in the inability
to maintain continued safe flight and
landing.
FAA’s Determination
The FAA is issuing this AD because
the agency has determined the unsafe
condition described previously is likely
to exist or develop in other products of
the same type design.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Boeing Alert
Service Bulletin 737–30A1064, Revision
2, dated June 26, 2020. The service
information describes procedures for
replacement and repetitive testing of the
E:\FR\FM\05APR1.SGM

Federal Register / Vol. 86, No. 63 / Monday, April 5, 2021 / Rules and Regulations
P5–9 window and pitot heat module,
and changing the anti-icing system to
automatically supply power to heat the
air data sensors.
This AD also requires 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, which the Director of the
Federal Register approved for
incorporation by reference as of June 26,
2019 (84 FR 23458, May 22, 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.
Minimum Equipment List (MEL)
Provision
The FAA allows operators to utilize a
MEL provision for time-limited
operation with certain equipment
inoperative, after which the system
must be fully restored. (See 14 CFR
91.213, 121.628, 125.201, and 129.14.)
This AD continues to allow use of an
existing FAA-approved MEL even if the
modified air data probe heat (ADPH)
system is inoperable, so long as the
operator’s existing FAA-approved MEL
has a provision to allow for this
inoperability.
AD Requirements
This AD requires accomplishing the
actions identified as ‘‘RC’’ (required for
compliance) in the Accomplishment
Instructions of Boeing Alert Service
Bulletin 737–30A1064, Revision 2,
dated June 26, 2020, described
previously, except as discussed under
‘‘Differences Between this AD and the
Service Information,’’ and except for
any differences identified as exceptions
in the regulatory text of this AD.
This AD also requires 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://

Differences Between This AD and the
Service Information
The FAA previously issued AD 2019–
09–01, Amendment 39–19635 (84 FR
VerDate Sep<11>2014
16:27 Apr 02, 2021
Jkt 253001
23458, May 22, 2019) (AD 2019–09–01),
which applies to the airplanes identified
in Boeing Alert Service Bulletin 737–
30A1064, Revision 1, dated October 18,
2017. This AD requires using Boeing
Alert Service Bulletin 737–30A1064,
Revision 2, dated June 26, 2020, which
adds Model 737–200 series airplanes
having variable numbers PK625 through
PK627 inclusive to the effectivity. The
unsafe condition and requirements are
the same for this AD and AD 2019–09–
01. This AD therefore applies only to
the 737–200 series airplanes having
variable numbers PK625 through PK627
inclusive.
Justification for Immediate Adoption
and Determination of the Effective Date
Section 553(b)(3)(B) of the
Administrative Procedure Act (APA) (5
U.S.C. 551 et seq.) authorizes agencies
to dispense with notice and comment
procedures for rules when the agency,
for ‘‘good cause,’’ finds that those
procedures are ‘‘impracticable,
unnecessary, or contrary to the public
interest.’’ Under this section, an agency,
upon finding good cause, may issue a
final rule without providing notice and
seeking comment prior to issuance.
Further, section 553(d) of the APA
authorizes agencies to make rules
effective in less than thirty days, upon
a finding of good cause.
There are currently no U.S.-registered
airplanes affected by this AD.
Accordingly, notice and opportunity for
prior public comment are unnecessary,
pursuant to 5 U.S.C. 553(b)(3). In
addition, for the foregoing reason(s), the
FAA finds that good cause exists
pursuant to 5 U.S.C. 553(d) for making
this amendment effective in less than 30
days.
Comments Invited
The FAA invites you to send any
written data, views, or arguments about
this final rule. Send your comments to
an address listed under ADDRESSES.
Include Docket No. FAA–2021–0190
and Project Identifier AD–2020–01348–
T at the beginning of your comments.
The most helpful comments reference a
specific portion of the final rule, explain
the reason for any recommended
change, and include supporting data.
The FAA will consider all comments
received by the closing date and may
amend this final rule because of those
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, to https://
www.regulations.gov, including any
personal information you provide. The
agency will also post a report
summarizing each substantive verbal
contact received about this final rule.
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 AD 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 AD,
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 AD. Submissions containing CBI
should be sent to Jeffrey W. Palmer,
Aerospace Engineer, Systems and
Equipment Section, FAA, Los Angeles
ACO Branch, 3960 Paramount
Boulevard, Lakewood, CA 90712–4137;
phone: 562–627–5851; fax: 562–627–
5210; email: jeffrey.w.palmer@faa.gov.
Any commentary that the FAA receives
that is not specifically designated as CBI
will be placed in the public docket for
this rulemaking.
Regulatory Flexibility Act
The requirements of the Regulatory
Flexibility Act (RFA) do not apply when
an agency finds good cause pursuant to
5 U.S.C. 553 to adopt a rule without
prior notice and comment. Because the
FAA has determined that it has good
cause to adopt this rule without notice
and comment, RFA analysis is not
required.
Costs of Compliance
Currently, there are no affected U.S.registered airplanes. For any affected
airplane that is imported and placed on
the U.S. Register in the future, the FAA
provides the following cost estimates to

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.

SUPPLEMENTARY INFORMATION:
Background
The FAA has received reports indicating that the pitot heat switch
is not always set to ON, which could result in misleading air data. 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 could ultimately result in the inability to
maintain continued safe flight and landing.
FAA's Determination
The FAA is issuing this AD because the agency has determined the
unsafe condition described previously is likely to exist or develop in
other products of the same type design.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing Alert Service Bulletin 737-30A1064,
Revision 2, dated June 26, 2020. The service information describes
procedures for replacement and repetitive testing of the
[[Page 17516]]
P5-9 window and pitot heat module, and changing the anti-icing system
to automatically supply power to heat the air data sensors.
This AD also requires 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, which the Director of the Federal Register
approved for incorporation by reference as of June 26, 2019 (84 FR
23458, May 22, 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.
Minimum Equipment List (MEL) Provision
The FAA allows operators to utilize a MEL provision for time-
limited operation with certain equipment inoperative, after which the
system must be fully restored. (See 14 CFR 91.213, 121.628, 125.201,
and 129.14.) This AD continues to allow use of an existing FAA-approved
MEL even if the modified air data probe heat (ADPH) system is
inoperable, so long as the operator's existing FAA-approved MEL has a
provision to allow for this inoperability.
AD Requirements
This AD requires accomplishing the actions identified as ``RC''
(required for compliance) in the Accomplishment Instructions of Boeing
Alert Service Bulletin 737-30A1064, Revision 2, dated June 26, 2020,
described previously, except as discussed under ``Differences Between
this AD and the Service Information,'' and except for any differences
identified as exceptions in the regulatory text of this AD.
This AD also requires 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-2021-0190.
Differences Between This AD and the Service Information
The FAA previously issued AD 2019-09-01, Amendment 39-19635 (84 FR
23458, May 22, 2019) (AD 2019-09-01), which applies to the airplanes
identified in Boeing Alert Service Bulletin 737-30A1064, Revision 1,
dated October 18, 2017. This AD requires using Boeing Alert Service
Bulletin 737-30A1064, Revision 2, dated June 26, 2020, which adds Model
737-200 series airplanes having variable numbers PK625 through PK627
inclusive to the effectivity. The unsafe condition and requirements are
the same for this AD and AD 2019-09-01. This AD therefore applies only
to the 737-200 series airplanes having variable numbers PK625 through
PK627 inclusive.
Justification for Immediate Adoption and Determination of the Effective
Date
Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and
comment procedures for rules when the agency, for ``good cause,'' finds
that those procedures are ``impracticable, unnecessary, or contrary to
the public interest.'' Under this section, an agency, upon finding good
cause, may issue a final rule without providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.
There are currently no U.S.-registered airplanes affected by this
AD. Accordingly, notice and opportunity for prior public comment are
unnecessary, pursuant to 5 U.S.C. 553(b)(3). In addition, for the
foregoing reason(s), the FAA finds that good cause exists pursuant to 5
U.S.C. 553(d) for making this amendment effective in less than 30 days.
Comments Invited
The FAA invites you to send any written data, views, or arguments
about this final rule. Send your comments to an address listed under
ADDRESSES. Include Docket No. FAA-2021-0190 and Project Identifier AD-
2020-01348-T at the beginning of your comments. The most helpful
comments reference a specific portion of the final rule, explain the
reason for any recommended change, and include supporting data. The FAA
will consider all comments received by the closing date and may amend
this final rule because of those 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, to
https://www.regulations.gov, including any personal information you
provide. The agency will also post a report summarizing each
substantive verbal contact received about this final rule.
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 AD 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 AD, 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 AD. Submissions containing CBI should be sent to Jeffrey
W. Palmer, Aerospace Engineer, Systems and Equipment Section, FAA, Los
Angeles ACO Branch, 3960 Paramount Boulevard, Lakewood, CA 90712-4137;
phone: 562-627-5851; fax: 562-627-5210; email:
[email protected]. Any commentary that the FAA receives that is
not specifically designated as CBI will be placed in the public docket
for this rulemaking.
Regulatory Flexibility Act
The requirements of the Regulatory Flexibility Act (RFA) do not
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt
a rule without prior notice and comment. Because the FAA has determined
that it has good cause to adopt this rule without notice and comment,
RFA analysis is not required.
Costs of Compliance
Currently, there are no affected U.S.-registered airplanes. For any
affected airplane that is imported and placed on the U.S. Register in
the future, the FAA provides the following cost estimates to comply
with this AD:
[[Page 17517]]
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product
----------------------------------------------------------------------------------------------------------------
Replacement (Boeing Alert Service 6 work-hours x $85 per $0 $510.
Bulletin 737-30A1064). hour = $510.
Repetitive tests (Boeing Alert Service 5 work-hours x $85 per 0 $425 per inspection cycle.
Bulletin 737-30A1064). hour = $425 per
inspection cycle.
J18 Junction box installation (Boeing Up to 75 work-hours x $85 23,614 Up to $29,989.
Service Bulletin 737-30-1067). per hour = Up to $6,375.
Installation of wire provisions (Boeing Up to 193 work-hours x $85 4,800 Up to $21,205.
Service Bulletin 737-30-1068). per hour = Up to $16,405.
----------------------------------------------------------------------------------------------------------------
The FAA has received no definitive data that would enable providing
cost estimates for the on-condition 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.
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
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, and
(2) Will not affect intrastate aviation in Alaska.
