SUPPLEMENTARY INFORMATION:

16:31 Oct 09, 2018
Jkt 247001
Discussion
We received reports of six aborted
takeoffs that occurred after engines did
not advance to the desired takeoff fan
speed. The aborted takeoffs happened
on the first takeoff of the day after the
airplane was exposed to sub-freezing
temperatures for more than six hours.
After further investigation, the operator
found water and ice in the pressure
sensor lines, which prevented the
pressure sensor from accurately
measuring the pressure. As a result,
CFM improved the FADEC and PHM
software to detect and accommodate
pressure sensor line freezing. This
condition, if not addressed, could result
in icing in the pressure sensor lines and
inaccurate pressure sensor readings,
failure of one or more engines, loss of
thrust control, and loss of the airplane.
We are issuing this AD to address the
unsafe condition on these products.
Related Service Information
We reviewed CFM Service Bulletin
(SB) LEAP–1A–73–00–0027–01A–
930A–D, Issue 001, dated July 30, 2018.
The SB introduces new FADEC and
PHM software and describes procedures
for replacing the software.
FAA’s Determination
We are issuing 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.
AD Requirements
This AD requires removing certain
FADEC and PHM software and
installing software that is eligible for
installation.
Differences Between the AD and the
Service Information
CFM SB LEAP–1A–73–00–0027–01A–
930A–D, Issue 001, dated July 30, 2018,
recommends that you install the new
FADEC and PHM software. This AD
requires that you install the new FADEC
and PHM software, and prohibits the
use of earlier FADEC and PHM software
versions.
Interim Action
We consider this AD interim action.
CFM is developing a modification that
will address the unsafe condition
identified in this AD. Once this
PO 00000
Frm 00015
Fmt 4700
Sfmt 4700
50819
modification is developed, approved,
and available, we might consider
additional rulemaking.
FAA’s Justification and Determination
of the Effective Date
An unsafe condition exists that
requires the immediate adoption of this
AD without providing an opportunity
for public comments prior to adoption.
The FAA has found that the risk to the
flying public justifies waiving notice
and comment prior to adoption of this
rule because the compliance time for the
required action is shorter than the time
necessary for the public to comment and
for us to publish the final rule. The
software must be removed and replaced
within 90 days to ensure that icing does
not develop in the pressure sensor lines
on the affected engines. Therefore, we
find good cause that notice and
opportunity for prior public comment
are impracticable. In addition, for the
reasons stated above, we find that good
cause exists for making this amendment
effective in less than 30 days.
Comments Invited
This AD is a final rule that involves
requirements affecting flight safety and
was not preceded by notice and an
opportunity for public comment.
However, we invite you to send any
written data, views, or arguments about
this final rule. Send your comments to
an address listed under the ADDRESSES
section. Include the docket number
FAA–2018–0855 and Product Identifier
2018–NE–31–AD at the beginning of
your comments. We specifically invite
comments on the overall regulatory,
economic, environmental, and energy
aspects of this final rule. We will
consider all comments received by the
closing date and may amend this final
rule 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 final rule.
Costs of Compliance
We estimate that this AD affects 82
engines installed on airplanes of U.S.
registry.
We estimate the following costs to
comply with 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.
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, and
(4) Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities

We are issuing 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.
AD Requirements
This AD requires removing certain FADEC and PHM software and
installing software that is eligible for installation.
Differences Between the AD and the Service Information
CFM SB LEAP-1A-73-00-0027-01A-930A-D, Issue 001, dated July 30,
2018, recommends that you install the new FADEC and PHM software. This
AD requires that you install the new FADEC and PHM software, and
prohibits the use of earlier FADEC and PHM software versions.
Interim Action
We consider this AD interim action. CFM is developing a
modification that will address the unsafe condition identified in this
AD. Once this modification is developed, approved, and available, we
might consider additional rulemaking.
FAA's Justification and Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD without providing an opportunity for public comments prior to
adoption. The FAA has found that the risk to the flying public
justifies waiving notice and comment prior to adoption of this rule
because the compliance time for the required action is shorter than the
time necessary for the public to comment and for us to publish the
final rule. The software must be removed and replaced within 90 days to
ensure that icing does not develop in the pressure sensor lines on the
affected engines. Therefore, we find good cause that notice and
opportunity for prior public comment are impracticable. In addition,
for the reasons stated above, we find that good cause exists for making
this amendment effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment. However, we invite you to send any written data, views, or
arguments about this final rule. Send your comments to an address
listed under the ADDRESSES section. Include the docket number FAA-2018-
0855 and Product Identifier 2018-NE-31-AD at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of this final rule. We will
consider all comments received by the closing date and may amend this
final rule 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 final rule.
Costs of Compliance
We estimate that this AD affects 82 engines installed on airplanes
of U.S. registry.
We estimate the following costs to comply with 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.
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, 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.
