Discussion
The FAA published a Notice of
Proposed Rulemaking (NPRM) in the
Federal Register on January 23, 2020
(85 FR 3871), prompted by reports of
two new unsafe conditions affecting
CFM LEAP–1B model turbofan engines:
(1) Increased fuel flow through certain
fuel nozzles due to fuel nozzle coking,
potentially causing distress to the static
structures of the high-pressure turbine
(HPT) and in-flight shutdown (IFSD) of
one or more engines; and (2) the
potential for undetected subsurface
anomalies formed during the
manufacturing process that could result
in uncontained failure of the HPT stage
2 disk.
The NPRM also resulted from
additional information related to two
unsafe conditions previously addressed
by AD 2018–25–09, Amendment 39–
19520 (83 FR 63559, December 11,
2018) (‘‘AD 2018–25–09’’), and AD
2019–12–01, Amendment 39–19656 (84
FR 28202, June 18, 2019) (‘‘AD 2019–
12–01’’), regarding: (1) Icing in the
pressure sensor lines, potentially
causing inaccurate pressure sensor
readings and loss of thrust control; and
(2) inadequate oil flow to the radial
drive shaft (RDS) bearing, which can
cause failure of the bearing and IFSD of
one or more engines. AD 2018–25–09
applied to all CFM LEAP–1B21, –1B23,
–1B25, –1B27, –1B28, –1B28B1,
–1B28B2, –1B28B2C, –1B28B3,
–1B28BBJ1, and –1B28BBJ2 model
turbofan engines. AD 2019–12–01
applied to CFM LEAP–1B21, –1B23,
–1B25, –1B27, –1B28, –1B28B1,
VerDate Sep<11>2014
15:54 Mar 11, 2020
Jkt 250001
–1B28B2, –1B28B3,–1B28B2C,
–1B28BBJ1, and –1B28BBJ2 model
turbofan engines with certain RDS
bearings installed. Thus, the FAA also
proposed to supersede the two
previously issued ADs addressing icing
in the pressure sensor lines and
inadequate oil flow to the RDS bearing.
The NPRM proposed to require
revising the ALS of the applicable CFM
LEAP–1B Engine Shop Manual and the
operator’s approved continuous
airworthiness maintenance program to:
(1) Add an ultrasonic inspection of the
HPT stage 2 disk to detect subsurface
anomalies formed during
manufacturing; (2) add an inspection of
the RDS bearing to address inadequate
oil flow to the RDS bearing; (3) require
monitoring and inspections of the fuel
nozzle to address the potential distress
to HPT static structures due to nozzle
coking; and (4) update the electronic
engine control (EEC) system software to
address potential for icing in the
pressure sensor lines.
The FAA is issuing this AD to address
the unsafe conditions on these products.
Comments
The FAA gave the public the
opportunity to participate in developing
this AD. The following presents the
comments received on the NPRM and
the FAA’s response to each comment.
Request To Use CFM Diagnostics for
Engine Monitoring To Detect Fuel
Nozzle Coking
A commenter asked whether CFM
Diagnostics reporting is an acceptable
method of compliance for CFM Service
Bulletin (SB) LEAP–1B–73–00–0030–
01A–930A–D, Issue 001, dated January
8, 2020 (‘‘SB 73–0030’’). The commenter
stated that CFM Diagnostics has created
a diagnostic report that includes the
limits published in SB 73–0030.
The FAA agrees that use of CFM
Diagnostics is an acceptable method of
compliance for the engine monitoring in
the ALS revisions required by this AD.
This AD requires revising the ALS to
include paragraph 6.B.(1) of CFM
Engine Shop Manual (ESM) Data
Module LEAP–1B–05–29–00–01A–
281B–C, Issue 001, dated January 9,
2020 (‘‘ESM 05–29’’), which requires
either engine monitoring or repetitive
borescope inspections specified in SB
73–0030 to detect fuel nozzle coking.
Given that SB 73–0030 recommends the
use of CFM Diagnostics to perform
engine monitoring, no change to this AD
is necessary.
The commenter also asked whether
switching between the engine
monitoring and borescope inspection
requirements is acceptable, because SB
PO 00000
Frm 00022
Fmt 4700
Sfmt 4700
73–0030 says that ‘‘You must do the
trend monitoring or BSI of the turbine
hardware,’’ which implies that only one
of the two methods must be used. The
commenter indicated that there may be
scenarios when a data interruption
occurs and they need to switch from
engine condition monitoring to a
borescope inspection.
The FAA agrees that switching
between the engine monitoring and
borescope inspection requirements is
acceptable because the FAA has
previously approved SB 73–0030, which
allows operators to use either option.
Based on the foregoing, no change to
this AD is necessary.
Request for Credit for Inspections of
Transfer Gearbox (TGB) Related to
Inadequate Oil Flow to RDS Bearing
A commenter requested that the AD
provide credit for inspections of the
TGB performed in accordance with CFM
SB LEAP–1B–72–00–0222–01A–930A–
D, Issue 007, dated May 17, 2019 (‘‘SB
72–0222’’). The commenter indicated
that, although the service bulletins refer
to different maintenance manual tasks,
both SB 72–0222 and CFM SB LEAP–
1B–72–00–0317–01A–930A–D, Issue
001, dated January 9, 2020 (‘‘SB 72–
0317’’), require inspections meeting the
same criteria.
The FAA agrees. This AD requires
revising the ALS to include paragraph
6.B.(2) of ESM 05–29, which requires
inspections of the RDS bearing as
specified in SB 72–0317. SB 72–0317
provides the conditions for taking credit
for inspections accomplished before the
issuance of SB 72–0317, including
inspections accomplished using SB 72–
0222. Operators who meet the
conditions specified in SB 72–0317 may
take credit for previous inspections as
part of their maintenance program.
However, no change to this AD is
necessary. Once an operator revises the
ALS as required by this AD, the operator
has fully complied with this AD.
Compliance with the inspections
remains mandatory as part of the ALS.
Support for the AD
The Boeing Company and the Air
Line Pilots Association expressed
support for the AD as written.
No Comments on the AD
United Airlines Engineering
commented that it reviewed the NPRM
and had no comments.
Conclusion
The FAA reviewed the relevant data,
considered the comments received, and
determined that air safety and the

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:
Discussion
The FAA published a Notice of Proposed Rulemaking (NPRM) in the
Federal Register on January 23, 2020 (85 FR 3871), prompted by reports
of two new unsafe conditions affecting CFM LEAP-1B model turbofan
engines: (1) Increased fuel flow through certain fuel nozzles due to
fuel nozzle coking, potentially causing distress to the static
structures of the high-pressure turbine (HPT) and in-flight shutdown
(IFSD) of one or more engines; and (2) the potential for undetected
subsurface anomalies formed during the manufacturing process that could
result in uncontained failure of the HPT stage 2 disk.
The NPRM also resulted from additional information related to two
unsafe conditions previously addressed by AD 2018-25-09, Amendment 39-
19520 (83 FR 63559, December 11, 2018) (``AD 2018-25-09''), and AD
2019-12-01, Amendment 39-19656 (84 FR 28202, June 18, 2019) (``AD 2019-
12-01''), regarding: (1) Icing in the pressure sensor lines,
potentially causing inaccurate pressure sensor readings and loss of
thrust control; and (2) inadequate oil flow to the radial drive shaft
(RDS) bearing, which can cause failure of the bearing and IFSD of one
or more engines. AD 2018-25-09 applied to all CFM LEAP-1B21, -1B23, -
1B25, -1B27, -1B28, -1B28B1, -1B28B2, -1B28B2C, -1B28B3, -1B28BBJ1, and
-1B28BBJ2 model turbofan engines. AD 2019-12-01 applied to CFM LEAP-
1B21, -1B23, -1B25, -1B27, -1B28, -1B28B1, -1B28B2, -1B28B3,-1B28B2C, -
1B28BBJ1, and -1B28BBJ2 model turbofan engines with certain RDS
bearings installed. Thus, the FAA also proposed to supersede the two
previously issued ADs addressing icing in the pressure sensor lines and
inadequate oil flow to the RDS bearing.
The NPRM proposed to require revising the ALS of the applicable CFM
LEAP-1B Engine Shop Manual and the operator's approved continuous
airworthiness maintenance program to: (1) Add an ultrasonic inspection
of the HPT stage 2 disk to detect subsurface anomalies formed during
manufacturing; (2) add an inspection of the RDS bearing to address
inadequate oil flow to the RDS bearing; (3) require monitoring and
inspections of the fuel nozzle to address the potential distress to HPT
static structures due to nozzle coking; and (4) update the electronic
engine control (EEC) system software to address potential for icing in
the pressure sensor lines.
The FAA is issuing this AD to address the unsafe conditions on
these products.
Comments
The FAA gave the public the opportunity to participate in
developing this AD. The following presents the comments received on the
NPRM and the FAA's response to each comment.
Request To Use CFM Diagnostics for Engine Monitoring To Detect Fuel
Nozzle Coking
A commenter asked whether CFM Diagnostics reporting is an
acceptable method of compliance for CFM Service Bulletin (SB) LEAP-1B-
73-00-0030-01A-930A-D, Issue 001, dated January 8, 2020 (``SB 73-
0030''). The commenter stated that CFM Diagnostics has created a
diagnostic report that includes the limits published in SB 73-0030.
The FAA agrees that use of CFM Diagnostics is an acceptable method
of compliance for the engine monitoring in the ALS revisions required
by this AD. This AD requires revising the ALS to include paragraph
6.B.(1) of CFM Engine Shop Manual (ESM) Data Module LEAP-1B-05-29-00-
01A-281B-C, Issue 001, dated January 9, 2020 (``ESM 05-29''), which
requires either engine monitoring or repetitive borescope inspections
specified in SB 73-0030 to detect fuel nozzle coking. Given that SB 73-
0030 recommends the use of CFM Diagnostics to perform engine
monitoring, no change to this AD is necessary.
The commenter also asked whether switching between the engine
monitoring and borescope inspection requirements is acceptable, because
SB 73-0030 says that ``You must do the trend monitoring or BSI of the
turbine hardware,'' which implies that only one of the two methods must
be used. The commenter indicated that there may be scenarios when a
data interruption occurs and they need to switch from engine condition
monitoring to a borescope inspection.
The FAA agrees that switching between the engine monitoring and
borescope inspection requirements is acceptable because the FAA has
previously approved SB 73-0030, which allows operators to use either
option. Based on the foregoing, no change to this AD is necessary.
Request for Credit for Inspections of Transfer Gearbox (TGB) Related to
Inadequate Oil Flow to RDS Bearing
A commenter requested that the AD provide credit for inspections of
the TGB performed in accordance with CFM SB LEAP-1B-72-00-0222-01A-
930A-D, Issue 007, dated May 17, 2019 (``SB 72-0222''). The commenter
indicated that, although the service bulletins refer to different
maintenance manual tasks, both SB 72-0222 and CFM SB LEAP-1B-72-00-
0317-01A-930A-D, Issue 001, dated January 9, 2020 (``SB 72-0317''),
require inspections meeting the same criteria.
The FAA agrees. This AD requires revising the ALS to include
paragraph 6.B.(2) of ESM 05-29, which requires inspections of the RDS
bearing as specified in SB 72-0317. SB 72-0317 provides the conditions
for taking credit for inspections accomplished before the issuance of
SB 72-0317, including inspections accomplished using SB 72-0222.
Operators who meet the conditions specified in SB 72-0317 may take
credit for previous inspections as part of their maintenance program.
However, no change to this AD is necessary. Once an operator revises
the ALS as required by this AD, the operator has fully complied with
this AD. Compliance with the inspections remains mandatory as part of
the ALS.
Support for the AD
The Boeing Company and the Air Line Pilots Association expressed
support for the AD as written.
No Comments on the AD
United Airlines Engineering commented that it reviewed the NPRM and
had no comments.
Conclusion
The FAA reviewed the relevant data, considered the comments
received, and determined that air safety and the
[[Page 14415]]
public interest require adopting this AD as proposed.
Related Service Information Under 1 CFR Part 51
The FAA reviewed CFM ESM Data Module LEAP-1B-05-21-03-01A-281B-C,
Issue 002, dated January 9, 2020 (``ESM 05-21''); and ESM 05-29. ESM
05-21 contains procedures for an ultrasonic inspection of the HPT stage
2 disk. ESM 05-29 contains procedures for inspection of the RDS
bearing, monitoring and inspections of the fuel nozzle, and the
required version of EEC system software. 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
The FAA estimates that this AD affects 162 engines installed on
airplanes of U.S. registry.
The FAA estimates the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Update ALS............................ 4 work-hours x $85 per $0 $340 $55,080

hour = 42.50.
RDS Borescope Inspection.............. 2 work-hours x 85 per 0 170 27,540
hour = 170.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary
replacements that would be required based on the results of the
inspection. The FAA has no way of determining the number of aircraft
that might need these replacements:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
RDS Replacement............................... 200 work-hours x $85 per hour = $30,500 $47,500

Replace Set of Fuel Nozzles................... 40 work-hours x $85 per hour = 120,000 123,400
$3,400.
----------------------------------------------------------------------------------------------------------------
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
The FAA has determined that 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) Will not affect intrastate aviation in Alaska, and
(3) 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.
