Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all Piaggio Aero Industries
S.p.A. Model P–180 airplanes. The
NPRM published in the Federal
Register on June 5, 2019 (84 FR 26025).
The NPRM proposed to correct an
unsafe condition for the specified
products and was based on mandatory
continuing airworthiness information
(MCAI) originated by the European
Aviation Safety Agency (EASA), which
is the Technical Agent for the Member
States of the European Union. EASA
issued AD No. 2017–0229, dated
November 21, 2017 (referred to after this
as ‘‘the MCAI’’), which states:
Related Service Information Under 1
CFR Part 51
An occurrence was reported of finding
insufficient sealing of a Steering Select/
Bypass Valve installed on the nose landing
gear (NLG) Steering Manifold of a P.180
aeroplane.
This condition, if not detected and
corrected, could lead to uncommanded
deflection of the NLG wheel, possibly
resulting in reduced control of the aeroplane
on the ground, with consequent damage to
the aeroplane and injury to occupants.
To address this potential unsafe condition,
PAI issued Service Bulletin (SB) 80–0325 to
provide inspection and rectification
instructions.
For the reason described above, this
[EASA] AD requires a leak test of the NLG
Steering Manifold and, depending on the
finding(s), accomplishment of applicable
corrective action(s). This [EASA] AD also
requires amendment of the applicable
Aircraft Flight Manual (AFM).
The MCAI further notes that airplanes
with NLG steering manifold part
number 72608 installed are known to
include manufacturing serial numbers
1001, 3001, 3003, 3004, 3006, 3007, and
3008, and also include airplanes that
have incorporated Piaggio Aerospace
Service Bulletin No. 80–0425, Revision
0, dated March 30, 2017, and Piaggio
Aerospace Service Bulletin No. 80–
0454, Revision 0, March 6, 2017. You

Comments
The FAA gave the public the
opportunity to participate in developing
this final rule. No comments were
received on the NPRM or on the
determination of the cost to the public.
Conclusion
The FAA reviewed the relevant data
and determined that air safety and the
public interest require adopting this
final rule as proposed.
The FAA reviewed Piaggio Aerospace
Service Bulletin No. 80–0325, Revision
0, dated August 10, 2017 (SB 80–0325),
and Piaggio Aerospace P.180 AVANTI
II/EVO Temporary Change No. 89, dated
August 30, 2017 (Temporary Change
89), to the airplane flight manual (AFM).
SB 80–0325 contains procedures for
doing a NLG steering manifold leakage
test. Temporary Change 89 contains
emergency operating procedures for the
pilot to follow if the NLG steering
system fails. 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.
Other Related Service Information
The FAA reviewed Piaggio Aerospace
Service Bulletin No. 80–0425, Revision
0, dated March 30, 2017 (SB 80–0425);
Piaggio Aerospace Service Bulletin No.
80–0454, Revision 0, March 6, 2017 (SB
80–0454); and Temporary Change No.
89 Errata Corrige, dated December 20,
2017 (Temporary Change 89EC). SB 80–
0425 and SB 80–0454 both contain
procedures for replacing the main
landing gear and the NLG steering
system on the applicable airplanes.
Temporary Change 89EC revises the
cover page of Temporary Change 89 to
clarify the applicability of the change.
Costs of Compliance
The FAA estimates that this AD will
affect 130 products of U.S. registry. The
FAA also estimates that it will take
about 2.5 work-hours per product to
comply with the basic requirements of
this AD. The average labor rate is $85
per work-hour.
Based on these figures, the FAA
estimates the cost of this AD on U.S.
operators to be $27,625, or $212.50 per
product.
E:\FR\FM\29SER1.SGM
29SER1
Federal Register / Vol. 85, No. 189 / Tuesday, September 29, 2020 / Rules and Regulations
If necessary, the FAA estimates that
replacing a NLG steering manifold
would take about 10 work-hours and
require parts costing $50,058, for a cost
of $50,908 per product. The FAA has no
way of determining the number of
products that may need these actions.
■
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,
(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.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain GE GEnx–1B64/P2,
–1B67/P2, –1B70/P2, –1B70C/P2,
–1B70/75/P2, –1B74/75/P2, –1B76/P2,
–1B76A/P2, and GEnx–2B67/P model
turbofan engines. The NPRM published
in the Federal Register on June 8, 2020
(85 FR 35021). The NPRM was
prompted by the detection of meltrelated freckles in the billet, which may
reduce the life limits of certain HPT
rotor stage 2 disks and a certain stages
6–10 compressor rotor spool. The NPRM
proposed to require the removal of
certain HPT rotor stage 2 disk and the
removal of a certain stages 6–10
compressor rotor spool before reaching
their new life limits. 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 final rule. The following presents
the comments received on the NPRM
and the FAA’s response to each
comment.
Request to List Part and Serial Numbers
GE requested that both the affected
part and serial numbers be listed in the
Applicability section of this AD instead
of the affected engine serial numbers.
The FAA agrees. The FAA recognizes
that affected HPT rotor stage 2 disks
could be moved from one engine to
another engine. The intent of this AD is
to mandate the removal of the affected
PO 00000
Frm 00016
Fmt 4700
Sfmt 4700
parts from service, regardless of the
engine on which they are installed. The
FAA is revising the Applicability
section of this AD as suggested by the
commenter. This change does not
expand the scope of this AD because the
number of affected engines installed on
airplanes of U.S. registry remains the
same in this final rule compared to what
was published in the NPRM.
Support for the AD
The Air Line Pilots Association,
International; the Boeing Company; and
United Airlines Engineering 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
final rule with the changes described
previously and minor editorial changes.
The FAA has determined that these
minor changes:
• Are consistent with the intent that
was proposed in the NPRM for
addressing the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.
The FAA also determined that these
changes will not increase the economic
burden on any operator or increase the
scope of this final rule.
Related Service Information
The FAA reviewed GE GEnx–1B
Service Bulletin (SB) 72–0473 R00,
dated April 14, 2020; GE GEnx–1B SB
72–0474 R00, dated April 14, 2020; and
GE GEnx–2B SB 72–0416 R00, dated
April 14, 2020. GE GEnx–1B SB 72–
0473 R00 describes procedures for
removing and replacing the HPT rotor
stage 2 disks on GE GEnx–1B model
engines. GE GEnx–1B SB 72–0474 R00
describes procedures for removing and
replacing the stages 6–10 compressor
rotor spool on GE GEnx–1B model
engines. GE GEnx–2B SB 72–0416 R00
describes procedures for removing and
replacing the HPT rotor stage 2 disks on
GE GEnx–2B model engines.
Costs of Compliance
The FAA estimates that this AD
affects two engines installed on
airplanes of U.S. registry; one engine
requires the HPT rotor stage 2 disk
replacement and one engine requires the
stages 6–10 compressor rotor spool
replacement.
The FAA estimates the following
costs to comply with this AD:

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to all Piaggio Aero
Industries S.p.A. Model P-180 airplanes. The NPRM published in the
Federal Register on June 5, 2019 (84 FR 26025). The NPRM proposed to
correct an unsafe condition for the specified products and was based on
mandatory continuing airworthiness information (MCAI) originated by the
European Aviation Safety Agency (EASA), which is the Technical Agent
for the Member States of the European Union. EASA issued AD No. 2017-
0229, dated November 21, 2017 (referred to after this as ``the MCAI''),
which states:
An occurrence was reported of finding insufficient sealing of a
Steering Select/Bypass Valve installed on the nose landing gear
(NLG) Steering Manifold of a P.180 aeroplane.
This condition, if not detected and corrected, could lead to
uncommanded deflection of the NLG wheel, possibly resulting in
reduced control of the aeroplane on the ground, with consequent
damage to the aeroplane and injury to occupants.
To address this potential unsafe condition, PAI issued Service
Bulletin (SB) 80-0325 to provide inspection and rectification
instructions.
For the reason described above, this [EASA] AD requires a leak
test of the NLG Steering Manifold and, depending on the finding(s),
accomplishment of applicable corrective action(s). This [EASA] AD
also requires amendment of the applicable Aircraft Flight Manual
(AFM).
The MCAI further notes that airplanes with NLG steering manifold
part number 72608 installed are known to include manufacturing serial
numbers 1001, 3001, 3003, 3004, 3006, 3007, and 3008, and also include
airplanes that have incorporated Piaggio Aerospace Service Bulletin No.
80-0425, Revision 0, dated March 30, 2017, and Piaggio Aerospace
Service Bulletin No. 80-0454, Revision 0, March 6, 2017. You may

Comments
The FAA gave the public the opportunity to participate in
developing this final rule. No comments were received on the NPRM or on
the determination of the cost to the public.
Conclusion
The FAA reviewed the relevant data and determined that air safety
and the public interest require adopting this final rule as proposed.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Piaggio Aerospace Service Bulletin No. 80-0325,
Revision 0, dated August 10, 2017 (SB 80-0325), and Piaggio Aerospace
P.180 AVANTI II/EVO Temporary Change No. 89, dated August 30, 2017
(Temporary Change 89), to the airplane flight manual (AFM). SB 80-0325
contains procedures for doing a NLG steering manifold leakage test.
Temporary Change 89 contains emergency operating procedures for the
pilot to follow if the NLG steering system fails. 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.
Other Related Service Information
The FAA reviewed Piaggio Aerospace Service Bulletin No. 80-0425,
Revision 0, dated March 30, 2017 (SB 80-0425); Piaggio Aerospace
Service Bulletin No. 80-0454, Revision 0, March 6, 2017 (SB 80-0454);

(Temporary Change 89EC). SB 80-0425 and SB 80-0454 both contain
procedures for replacing the main landing gear and the NLG steering
system on the applicable airplanes. Temporary Change 89EC revises the
cover page of Temporary Change 89 to clarify the applicability of the
change.
Costs of Compliance
The FAA estimates that this AD will affect 130 products of U.S.
registry. The FAA also estimates that it will take about 2.5 work-hours
per product to comply with the basic requirements of this AD. The
average labor rate is $85 per work-hour.
Based on these figures, the FAA estimates the cost of this AD on
U.S. operators to be $27,625, or $212.50 per product.
[[Page 60897]]
If necessary, the FAA estimates that replacing a NLG steering
manifold would take about 10 work-hours and require parts costing
$50,058, for a cost of $50,908 per product. The FAA has no way of
determining the number of products that may need these actions.
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,
(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.

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.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
2020-19-10 Piaggio Aero Industries S.p.A.: Amendment 39-21253;
Docket No. FAA-2019-0412; Product Identifier 2018-CE-030-AD.
(a) Effective Date
This AD is effective November 3, 2020.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Piaggio Aero Industries S.p.A. Model P-180
airplanes, certificated in any category.
(d) Subject
Air Transport Association of America (ATA) Code 32: Landing
Gear.
(e) Reason
This AD was prompted by mandatory continuing airworthiness
information (MCAI) originated by an aviation authority of another
country to identify and correct an unsafe condition on an aviation
product. The MCAI describes the unsafe condition as insufficient
sealing of a steering select/bypass valve installed in the nose
landing gear (NLG) manifold. The FAA is issuing this AD to detect
and correct insufficient sealing of the steering select/bypass valve
in the NLG steering manifold, which could lead to un-commanded NLG
wheel turns with consequent lateral runway departure.
(f) Actions and Compliance
Unless already done, do the following actions in paragraphs
(f)(1) through (3) of this AD.
(1) For airplanes with NLG steering manifold part number (P/N)
72608 installed: (i) Within 50 hours time-in service after the
effective date of this AD, do a steering manifold pressure leakage
test and, if there is steering actuator movement during the test,
replace the NLG steering manifold and repeat the test by following
the Accomplishment Instructions, procedure steps (1) through (24),
in Piaggio Aerospace Service Bulletin No. 80-0325, Revision 0, dated
August 10, 2017.
(ii) If steering actuator movement occurs during procedure step
(9) or procedure step (15) of the leakage test required in paragraph
(f)(1)(i) of this AD, replacing the NLG steering manifold and
repeating the steering manifold pressure leakage test is required
before further flight.
(2) For all airplanes, after the effective date of this AD, do
not install NLG steering manifold P/N 72608 on any airplane unless
it has been inspected as specified in paragraph (f)(1) of this AD
and no steering actuator movement occurred.
(3) For all airplanes, within 30 days after the effective date
of this AD, revise the airplane flight manual (AFM) by replacing
certain pages in the Emergency Procedures section of the AFM by
following the Instructions in Piaggio Aerospace P.180 AVANTI II/EVO
Temporary Change No. 89, dated August 30, 2017.
