SUPPLEMENTARY INFORMATION:
Background
EASA, which is the Technical Agent
for the Member States of the European
Union, has issued EASA AD 2021–0096,
dated March 31, 2021 (EASA AD 2021–
0096), to correct an unsafe condition for
Leonardo S.p.A. Helicopters, formerly
Finmeccanica S.p.A., AgustaWestland
S.p.A., Agusta S.p.A.; and
AgustaWestland Philadelphia
Corporation, formerly Agusta Aerospace
Corporation, Model A119 and AW119
MKII helicopters, all serial numbers.
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to all Leonardo S.p.a. Model A119
and AW119 MKII helicopters. The
NPRM published in the Federal
Register on July 20, 2021 (86 FR 38242).
The NPRM was prompted by reports of
abnormal play on the collective torque
tube on two Model AW119 MKII
helicopters. Investigations revealed that
PO 00000
Frm 00001
Fmt 4700
Sfmt 4700
these events were due to an erroneous
manufacturing process, affecting certain
collective torque tube assemblies. The
affected batch numbers were identified.
Leonardo S.p.a. Model A119 helicopters
are similar in design and may be subject
to the same unsafe condition revealed
on the Model AW119 MKII helicopters.
The NPRM proposed to require
repetitive inspections of affected torque
tube assemblies for any deficiency and
corrective action if necessary; and the
replacement of any affected part with a
serviceable part, which is terminating
action for the repetitive inspections, as
specified in EASA AD 2021–0096.
The FAA is issuing this AD to address
abnormal play on the collective torque
tube, which could result in reduced
control of the helicopter, resulting in a
forced landing and consequent damage
to the helicopter and injury to
occupants. See EASA AD 2021–0096 for
additional background information.
Discussion of Final Airworthiness
Directive
Comments
The FAA received one comment from
Air Methods Corporation (Air Methods).
The following presents the comment
received on the NPRM and the FAA’s
response to that comment.
Request To Apply Inspection and
Replacement Criteria to Additional
Torque Tube Batch Numbers
Air Methods requested that paragraph
(h)(6) in the ‘‘Exceptions to EASA AD
2021–0096’’ paragraph of the proposed
AD be revised to allow additional
appropriate actions for torque tubes that
have batch numbers that are ‘‘doubted.’’
The commenter stated that applying the
Group 1 inspection and replacement
criteria to any torque tube, regardless of
batch number, is the most conservative
action possible within the scope of the
service information referenced in EASA
AD 2021–0096.
The FAA does not agree with the
commenter’s request. The intent of this
AD is match the intent of EASA AD
2021–0096, which does not include
torque tube batch numbers that are
unknown or ‘‘in doubt’’ within the
Group 1 helicopters. Also, if a
‘‘doubted’’ torque tube batch number is
ultimately determined not to be within
the number ranges designated as Group
1 or Group 2 in EASA AD 2021–0096,
then it would be unnecessary to subject
E:\FR\FM\26NOR1.SGM

67302
Federal Register / Vol. 86, No. 225 / Friday, November 26, 2021 / Rules and Regulations
that torque tube to the inspection and
replacement requirements for Group 1
helicopters. In addition, once this AD is
published, any person may request an
alternative method of compliance
(AMOC) by using the procedures
specified in paragraph (j) of this AD.
The FAA has not changed this AD
regarding this issue.
Conclusion
The FAA reviewed the relevant data,
considered the comment received, and
determined that air safety requires
adopting this AD as proposed. Except
for minor editorial changes this AD is
adopted as proposed in the NPRM.
None of the changes will increase the
economic burden on any operator.
Accordingly, the FAA is issuing this AD
to address the unsafe condition on these
products.
Related Service Information Under 1
CFR Part 51
EASA AD 2021–0096 requires
repetitive inspections of the affected
torque tube assemblies for any
deficiency (i.e., any play) by marking
the torque tube assembly and the collar
and applying specific loads to
determine if there is any play; and
replacement of any affected part that has
any play with a serviceable part. EASA
AD 2021–0096 also requires the
eventual replacement of any affected
part with a serviceable part, and
specifies that replacement of an affected
part on a helicopter constitutes
terminating action for the repetitive
inspections for that helicopter.
This material 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.
Differences Between This AD and the
EASA AD
EASA AD 2021–0096 supersedes
EASA AD 2019–0057, dated March 20,
2019 (EASA AD 2019–0057). The Group
1 helicopters identified in both EASA
AD 2021–0096 and EASA AD 2019–
0057 are helicopters with collective
stick torque tube assemblies having part
number (P/N) 109–0011–03–105 and
batch number 823207 or earlier.
Paragraph (1) of EASA AD 2021–0096
addresses Group 1 helicopters that have
incorporated the actions required by
paragraph (2) of EASA AD 2019–0057.
The FAA did not issue an AD that
corresponds to EASA AD 2019–0057,
therefore, this AD requires, for Group 1
helicopters, an initial inspection of the
torque tube assembly within 50 hours
time-in-service (TIS) after the effective
date of the FAA AD and repetitive
inspections thereafter at intervals not to
exceed 100 hours TIS.
In addition, where paragraph (5) of
EASA AD 2021–0096 specifies, for
Group 1 helicopters, replacement of an
affected part with a serviceable part
‘‘within 36 months after April 3, 2019
[the effective date of EASA AD 2019–
0057]’’, for this AD, the compliance time
is within 24 months after the effective
date of this AD.
Costs of Compliance
The FAA estimates that this AD
affects 136 helicopters of U.S. registry.
The FAA estimates the following costs
to comply with this AD:
ESTIMATED COSTS
Action
Labor cost
Inspection ...............................
2 work-hours × $85 per hour
= $170 per inspection cycle.
16 work-hours × $85 per hour
= $1,360.
Replacement ..........................
The FAA has included all known
costs in its cost estimate. According to
the manufacturer, however, some of the
costs of this AD may be covered under
warranty, thereby reducing the cost
impact on affected operators.

SUPPLEMENTARY INFORMATION:
Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2021-0096, dated March 31, 2021
(EASA AD 2021-0096), to correct an unsafe condition for Leonardo S.p.A.
Helicopters, formerly Finmeccanica S.p.A., AgustaWestland S.p.A.,
Agusta S.p.A.; and AgustaWestland Philadelphia Corporation, formerly
Agusta Aerospace Corporation, Model A119 and AW119 MKII helicopters,

batch number, is the most conservative action possible within the scope
of the service information referenced in EASA AD 2021-0096.
The FAA does not agree with the commenter's request. The intent of
this AD is match the intent of EASA AD 2021-0096, which does not
include torque tube batch numbers that are unknown or ``in doubt''
within the Group 1 helicopters. Also, if a ``doubted'' torque tube
batch number is ultimately determined not to be within the number
ranges designated as Group 1 or Group 2 in EASA AD 2021-0096, then it
would be unnecessary to subject
[[Page 67302]]
that torque tube to the inspection and replacement requirements for
Group 1 helicopters. In addition, once this AD is published, any person
may request an alternative method of compliance (AMOC) by using the
procedures specified in paragraph (j) of this AD. The FAA has not
changed this AD regarding this issue.
Conclusion
The FAA reviewed the relevant data, considered the comment
received, and determined that air safety requires adopting this AD as
proposed. Except for minor editorial changes this AD is adopted as
proposed in the NPRM. None of the changes will increase the economic
burden on any operator. Accordingly, the FAA is issuing this AD to
address the unsafe condition on these products.
Related Service Information Under 1 CFR Part 51
EASA AD 2021-0096 requires repetitive inspections of the affected
torque tube assemblies for any deficiency (i.e., any play) by marking
the torque tube assembly and the collar and applying specific loads to
determine if there is any play; and replacement of any affected part
that has any play with a serviceable part. EASA AD 2021-0096 also
requires the eventual replacement of any affected part with a
serviceable part, and specifies that replacement of an affected part on
a helicopter constitutes terminating action for the repetitive
inspections for that helicopter.
This material 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.
Differences Between This AD and the EASA AD
EASA AD 2021-0096 supersedes EASA AD 2019-0057, dated March 20,
2019 (EASA AD 2019-0057). The Group 1 helicopters identified in both
EASA AD 2021-0096 and EASA AD 2019-0057 are helicopters with collective
stick torque tube assemblies having part number (P/N) 109-0011-03-105
and batch number 823207 or earlier. Paragraph (1) of EASA AD 2021-0096
addresses Group 1 helicopters that have incorporated the actions
required by paragraph (2) of EASA AD 2019-0057. The FAA did not issue
an AD that corresponds to EASA AD 2019-0057, therefore, this AD
requires, for Group 1 helicopters, an initial inspection of the torque
tube assembly within 50 hours time-in-service (TIS) after the effective
date of the FAA AD and repetitive inspections thereafter at intervals
not to exceed 100 hours TIS.
In addition, where paragraph (5) of EASA AD 2021-0096 specifies,
for Group 1 helicopters, replacement of an affected part with a
serviceable part ``within 36 months after April 3, 2019 [the effective
date of EASA AD 2019-0057]'', for this AD, the compliance time is
within 24 months after the effective date of this AD.
Costs of Compliance
The FAA estimates that this AD affects 136 helicopters of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Inspection....................... 2 work-hours x $85 $0 $170 per inspection $23,120 per
per hour = $170 cycle. inspection cycle.
per inspection
cycle.
Replacement...................... 16 work-hours x $85 $9,928 $11,288............ $1,535,168.
per hour = $1,360.
----------------------------------------------------------------------------------------------------------------
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some of the costs of this AD
may be covered under warranty, thereby reducing the cost impact on
affected operators.
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.

replacement must be done within 24 months after the effective date
of this AD.
(5) Where the service information referenced in EASA AD 2021-
0096 specifies to return a torque tube assembly to the manufacturer,
this AD does not include that requirement.
(6) Where the service information referenced in EASA AD 2021-
0096 specifies to contact the manufacturer ``in case of doubt''
regarding the batch number on a torque tube assembly, determining
the batch number is required by this AD but contacting the
manufacturer is not required.
(7) This AD does not mandate compliance with the ``Remarks''
section of EASA AD 2021-0096.
(i) No Reporting Requirement
Although the service information referenced in EASA AD 2021-0096
specifies to submit certain information to the manufacturer, this AD
does not include that requirement.
