Discussion
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD No. 2018–
0156, dated July 24, 2018 (EASA AD
2018–0156) to correct an unsafe
condition for Leonardo (formerly
Finmeccanica S.p.A., AgustaWestland
S.p.A., Agusta S.p.A.; and
AgustaWestland Philadelphia
Corporation, formerly Agusta Aerospace
Corporation) Model A119 and
AW119MKII helicopters with 90-degree
TGB part number (P/N) 109–0440–06–
101 or P/N 109–0440–06–105 having
serial number 167, 169 through 172
inclusive, 215 through 225 inclusive,
227, 230, 232, 233, AW268, K3, K16,
M47, or L29, installed. EASA advises of
two reported occurrences of corrosion
on the internal surface of the 90-degree
TGB shaft installed on Model A119
helicopters. Further analysis identified a
specific batch of parts that may be
susceptible to similar conditions. Due to
design similarity, Model AW119MKII
helicopters are also affected.
EASA states that this condition, if not
detected and corrected, could lead to
failure of the tail rotor, possibly
resulting in reduced control of the
helicopter. Accordingly, EASA AD
2018–0156 requires performing
repetitive endoscope inspections on the
internal surface of the 90-degree TGB
output shaft for corrosion and
depending on the findings, replacing the
TGB. EASA further states EASA AD
2018–0156 is considered an interim
action and further AD action may
follow.
FAA’s Determination
These helicopters have been approved
by EASA and are approved for operation
in the United States. Pursuant to the
FAA’s bilateral agreement with the
European Union, EASA has notified the
FAA about the unsafe condition
described in its AD. The FAA is
proposing this AD after evaluating all
known relevant information and
determining that an unsafe condition is
E:\FR\FM\24APP1.SGM
24APP1
Federal Register / Vol. 85, No. 80 / Friday, April 24, 2020 / Proposed Rules
likely to exist or develop on other
helicopters of the same type designs.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Leonardo
Helicopters Alert Service Bulletin No.
119–090, dated July 23, 2018, for Model
A119 and AW119MKII helicopters,
which contains procedures for
conducting an endoscope inspection of
the internal surface of the 90-degree
TGB output shaft for corrosion. This
service information also specifies
replacing the TGB if corrosion is found.
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.
Proposed AD Requirements
This proposed AD would require
compliance with certain procedures
described in the manufacturer’s service
bulletin. For helicopters with an
affected 90-degree TGB output shaft
installed, this proposed AD would
require within 25 hours time-in-service
(TIS) or 3 months, whichever comes
first, and thereafter at intervals not to
exceed 100 hours TIS or 6 months,
whichever occurs first, borescope
inspecting the internal surface of the 90degree TGB output shaft for corrosion.
If there is corrosion, this proposed AD
would require removing the TGB from
service before further flight.
khammond on DSKJM1Z7X2PROD with PROPOSALS
Interim Action
The FAA considers this proposed AD
to be an interim action. An investigation
is ongoing and if final action is later
identified, the FAA might consider
further rulemaking then.
Costs of Compliance
The FAA estimates that this proposed
AD would affect 96 helicopters of U.S.
Registry. The FAA also estimates that
operators may incur the following costs
in order to comply with this proposed
AD. Labor costs are estimated at $85 per
work-hour.
Borescope inspecting the 90-degree
TGB output shaft would take about 3
work-hours for an estimated cost of
$255 per helicopter and $24,480 for the
U.S. fleet per inspection cycle.
Replacing a (overhauled) TGB would
take about 18 work-hours and parts
would cost about $49,000 (overhauled)
for an estimated cost of $50,530 per
helicopter.
According to Leonardo’s service
information, some of the costs of this
proposed AD may be covered under
warranty, thereby reducing the cost
impact on affected individuals. The
VerDate Sep<11>2014
16:06 Apr 23, 2020
Jkt 250001
FAA does not control warranty coverage
by Leonardo. Accordingly, the FAA has
included all costs in the cost estimate.
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 determined that this
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would 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, I certify
this proposed regulation:
(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.

operation in the United States. Pursuant to the FAA's bilateral
agreement with the European Union, EASA has notified the FAA about the
unsafe condition described in its AD. The FAA is proposing this AD
after evaluating all known relevant information and determining that an
unsafe condition is
[[Page 22971]]
likely to exist or develop on other helicopters of the same type
designs.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Leonardo Helicopters Alert Service Bulletin No.
119-090, dated July 23, 2018, for Model A119 and AW119MKII helicopters,
which contains procedures for conducting an endoscope inspection of the
internal surface of the 90-degree TGB output shaft for corrosion. This
service information also specifies replacing the TGB if corrosion is
found.
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.
Proposed AD Requirements
This proposed AD would require compliance with certain procedures
described in the manufacturer's service bulletin. For helicopters with
an affected 90-degree TGB output shaft installed, this proposed AD
would require within 25 hours time-in-service (TIS) or 3 months,
whichever comes first, and thereafter at intervals not to exceed 100
hours TIS or 6 months, whichever occurs first, borescope inspecting the
internal surface of the 90-degree TGB output shaft for corrosion. If
there is corrosion, this proposed AD would require removing the TGB
from service before further flight.
Interim Action
The FAA considers this proposed AD to be an interim action. An
investigation is ongoing and if final action is later identified, the
FAA might consider further rulemaking then.
Costs of Compliance
The FAA estimates that this proposed AD would affect 96 helicopters
of U.S. Registry. The FAA also estimates that operators may incur the
following costs in order to comply with this proposed AD. Labor costs
are estimated at $85 per work-hour.
Borescope inspecting the 90-degree TGB output shaft would take
about 3 work-hours for an estimated cost of $255 per helicopter and
$24,480 for the U.S. fleet per inspection cycle.
Replacing a (overhauled) TGB would take about 18 work-hours and
parts would cost about $49,000 (overhauled) for an estimated cost of
$50,530 per helicopter.
According to Leonardo's service information, some of the costs of
this proposed AD may be covered under warranty, thereby reducing the
cost impact on affected individuals. The FAA does not control warranty
coverage by Leonardo. Accordingly, the FAA has included all costs in
the cost estimate.
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 determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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, I certify this proposed regulation:
(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.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 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):
Leonardo S.p.a.: Docket No. FAA-2020-0411; Product Identifier 2018-
SW-061-AD.
(a) Applicability
This AD applies to Leonardo S.p.a. Model A119 and AW119MKII
helicopters, certified in any category, with 90-degree tail rotor
gearbox (TGB) part number (P/N) 109-0440-06-101 or 109-0440-06-105
having serial number 167, 169 through 172 inclusive, 215 through 225
inclusive, 227, 230, 232, 233, AW268, K3, K16, M47, or L29,
installed.
(b) Unsafe Condition
This AD defines the unsafe condition as corrosion on the
internal surface of the 90-degree TGB output shaft. This condition
could result in failure of the 90-degree TGB output shaft and
reduced control of the helicopter.
(c) Comments Due Date
The FAA must receive comments by June 23, 2020.
(d) Compliance
You are responsible for performing each action required by this
AD within the specified compliance time unless it has already been
accomplished prior to that time.
(e) Required Actions
(1) Within 25 hours time-in-service (TIS) or 3 months, whichever
occurs first, and thereafter at intervals not to exceed 100 hours
TIS or 6 months, whichever occurs first, borescope inspect the
