SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2005–23–09,
Amendment 39–14367 (70 FR 67901,
November 9, 2005), (‘‘AD 2005–23–09’’).
AD 2005–23–09 applied to all GE CF6–
80E1A1, –80E1A2, –80E1A3, –80E1A4,
and –80E1A4/B model turbofan engines.
The NPRM published in the Federal
Register on January 21, 2020 (85 FR
3284). The NPRM was prompted by GE
performing an updated lifing analysis
on the HPC case. As a result, GE found
additional locations on the cases
E:\FR\FM\07JYR1.SGM
07JYR1
40587
Federal Register / Vol. 85, No. 130 / Tuesday, July 7, 2020 / Rules and Regulations
requiring FPI, revised the inspection
interval for performing FPI of the
existing location, and added an
additional P/N HPC case that requires
inspection. The NPRM proposed to
require an update of the ALS of GE
Engine Manual GEK99376 and the
operator’s existing CAMP. The FAA is
issuing this AD to address the unsafe
condition 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 for Clarification on Task
Referenced in AD
EASA and Delta Airlines (Delta)
requested clarification on whether
TASK 05–21–02–200–001, dated
September 15, 2015, referenced in the
AD and in the docket, should be from
Revision 47 or from Revision 48 of GE
CF6–80E1 Engine Manual GEK99376,
dated September 15, 2019 (‘‘GE Engine
Manual’’). Delta further questioned
whether the task should have the same
date as the GE Engine Manual.
The FAA agrees that TASK 05–21–
02–200–001, dated September 15, 2015,
in Revision 48 of the GE Engine Manual
is referenced correctly in this AD. The
FAA notes that the task has a different
date than the GE Engine Manual and the
task is dated correctly in the NPRM.
This task from Revision 48 of the GE
Engine Manual will be uploaded to the
docket upon publication of the final
rule.
Request To Include Reference to Later
Revisions of Engine Manual
Delta requested that the FAA include
a reference to ‘‘and later approved
revisions’’ when referencing the GE
Engine Manual in paragraph (g) of this
AD.
The FAA disagrees because later
revisions of the GE Engine Manual
cannot be referenced in an AD.
Support for the AD
The Air Line Pilots Association,
International, expressed support for the
AD as written.
Conclusion
The FAA reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting this AD
as proposed.

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
VerDate Sep<11>2014
16:03 Jul 06, 2020
Jkt 250001
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.

67901, November 9, 2005), (``AD 2005-23-09''). AD 2005-23-09 applied to
all GE CF6-80E1A1, -80E1A2, -80E1A3, -80E1A4, and -80E1A4/B model
turbofan engines. The NPRM published in the Federal Register on January
21, 2020 (85 FR 3284). The NPRM was prompted by GE performing an
updated lifing analysis on the HPC case. As a result, GE found
additional locations on the cases
[[Page 40587]]
requiring FPI, revised the inspection interval for performing FPI of
the existing location, and added an additional P/N HPC case that
requires inspection. The NPRM proposed to require an update of the ALS
of GE Engine Manual GEK99376 and the operator's existing CAMP. The FAA
is issuing this AD to address the unsafe condition 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 for Clarification on Task Referenced in AD
EASA and Delta Airlines (Delta) requested clarification on whether
TASK 05-21-02-200-001, dated September 15, 2015, referenced in the AD
and in the docket, should be from Revision 47 or from Revision 48 of GE
CF6-80E1 Engine Manual GEK99376, dated September 15, 2019 (``GE Engine
Manual''). Delta further questioned whether the task should have the
same date as the GE Engine Manual.
The FAA agrees that TASK 05-21-02-200-001, dated September 15,
2015, in Revision 48 of the GE Engine Manual is referenced correctly in
this AD. The FAA notes that the task has a different date than the GE
Engine Manual and the task is dated correctly in the NPRM. This task
from Revision 48 of the GE Engine Manual will be uploaded to the docket
upon publication of the final rule.
Request To Include Reference to Later Revisions of Engine Manual
Delta requested that the FAA include a reference to ``and later
approved revisions'' when referencing the GE Engine Manual in paragraph
(g) of this AD.
The FAA disagrees because later revisions of the GE Engine Manual
cannot be referenced in an AD.
Support for the AD
The Air Line Pilots Association, International, expressed support
for the AD as written.
Conclusion
The FAA reviewed the relevant data, considered the comments
received, and determined that air safety and the public interest
require adopting this AD as proposed.
Related Service Information Under 1 CFR Part 51
The FAA reviewed TASK 05-21-02-200-001, dated September 15, 2015,
from ESM 05-21-02, Life Limits 001 High Pressure Compressor HPC--
Scheduled Maintenance Checks, of the GE CF6-80E1 Engine Manual
GEK99376, Revision 48, dated September 15, 2019. The service
information describes procedures for performing FPIs of the HPC case.
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 20 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 of Engine Manual........... 2 work-hours x $85 per $0 $170 $3,400
hour = $170.

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.
List of Subjects in 14 CFR Part 39

reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
