Federal Register / Vol. 86, No. 146 / Tuesday, August 3, 2021 / Proposed Rules
(d) Deposit account records—(1)
Informal revocable trusts. The
beneficiaries of an informal revocable
trust must be specifically named in the
deposit account records of the insured
depository institution.
(2) Formal revocable trusts. The title
of a formal trust account must include
terminology sufficient to identify the
account as a trust account, such as
‘‘family trust’’ or ‘‘living trust,’’ or must
otherwise be identified as a
testamentary trust in the account
records of the insured depository
institution. If eligible beneficiaries of
such formal revocable trust are
specifically named in the deposit
account records of the insured
depository institution, the FDIC shall
presume the continued validity of the
named beneficiary’s interest in the trust
consistent with § 330.5(a).
(e) Commingled deposits of
bankruptcy trustees. If a bankruptcy
trustee appointed under title 11 of the
United States Code commingles the
funds of various bankruptcy estates in
the same account at an insured
depository institution, the funds of each
title 11 bankruptcy estate will be added
together and insured up to the SMDIA,
separately from the funds of any other
such estate.
(f) Deposits excluded from coverage
under this section—(1) Revocable trust
co-owners that are sole beneficiaries of
a trust. If the co-owners of an informal
or formal revocable trust are the trust’s
sole beneficiaries, deposits held in
connection with the trust are treated as
joint ownership deposits under § 330.9.
(2) Employee benefit plan deposits.
Deposits of employee benefit plans,
even if held in connection with a trust,
are treated as employee benefit plan
deposits under § 330.14.
(3) Investment company deposits.
This section shall not apply to deposits
of trust funds belonging to a trust
classified as a corporation under
§ 330.11(a)(2).
(4) Insured depository institution as
trustee of an irrevocable trust. Deposits
held by an insured depository
institution in its capacity as trustee of
an irrevocable trust are insured as
provided in § 330.12.

Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
The FAA proposes to adopt a
new airworthiness directive (AD) for all
Diamond Aircraft Industries GmbH
Models DA 42, DA 42 NG, and DA 42
M–NG airplanes. This proposed AD was
prompted by mandatory continuing
airworthiness information (MCAI)

another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as failure of the nose landing
gear (NLG) actuator attachment lever
and detachment from the NLG leg. This
proposed AD would require repetitively
inspecting the NLG actuator attachment
lever for cracks and damage and taking
any necessary corrective actions. The
FAA is proposing this AD to address the
unsafe condition on these products.

Background
The European Union Aviation Safety
Agency (EASA), which is the Technical
Agent for the Member States of the
European Union, has issued EASA AD
2019–0066, dated March 27, 2019
(referred to after this as ‘‘the MCAI’’), to
correct an unsafe condition for Diamond
Aircraft Industries GmbH (Austria) and
Diamond Aircraft Industries Inc.
(Canada) Model DA 42, DA 42 M, DA
42 NG, and DA 42 M–NG airplanes. The
MCAI states:
An occurrence was reported of a failed
NLG actuator attachment lever, resulting in
disconnection from the NLG leg. When the
landing gear (LG) was retracted, the NLG
actuator interfered with the rudder control
rods, forcing the rudder into left-hand
deflection. After lowering the LG, full rudder
control was restored. The investigation
results showed that the actuator lever failed
due to a crack that had developed over a
longer time period.
This condition, if not detected and
corrected, could lead to restricted rudder
travel in LG retracted configuration, possibly
resulting in reduced control of the aeroplane.
To address this potential unsafe condition,
[Diamond Aircraft Industries] DAI issued the
applicable [mandatory service bulletin] MSB,
providing instructions to inspect the affected
part.
For the reason described above, this
[EASA] AD requires repetitive inspections of
the NLG leg actuator attachment lever and,
depending on findings, replacement of the
NLG leg.

Related Service Information Under 1
CFR Part 51
The FAA reviewed Diamond Aircraft
Industries Work Instruction WI–MSB
42–136 and WI–MSB 42NG–078,
Revision 1, dated January 24, 2019
(published as one document with
Mandatory Service Bulletin MSB 42–
136/1 and MSB 42NG–078, dated
January 24, 2019). This service
information provides instructions for
repetitively inspecting the NLG actuator

attachment lever with replacement of
the NLG leg assembly as necessary. 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.
FAA’s Determination
This product has been approved by
the aviation authority of another
country and is approved for operation in
the United States. Pursuant to the FAA’s
bilateral agreement with this State of
Design Authority, it has notified the
FAA of the unsafe condition described
in the MCAI and service information
referenced above. The FAA is issuing
this NPRM after determining the unsafe
condition described previously is likely
to exist or develop on other products of
the same type design.
41787
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 MCAI applies to Models DA 42,
DA 42 M, DA 42 NG, and DA 42 M–NG
airplanes. This proposed AD would not
apply to the Model DA 42 M because
they do not have an FAA type
certificate.
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 above, I
certify this proposed regulation:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866,
(2) Would not affect intrastate
aviation in Alaska, and
(3) Would not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.
Costs of Compliance
List of Subjects in 14 CFR Part 39
The FAA estimates that this AD, if
adopted as proposed, would affect 40
airplanes of U.S. registry. The FAA also
estimates that it would take about 1
work-hour per airplane to comply with
the inspection requirement of this
proposed AD, and no parts would be
necessary. Based on these figures, the
FAA estimates the cost of the inspection
for U.S. operators to be $3,400, or $85
per airplane.
In addition, the FAA estimates that
any necessary replacement actions
would take about 6 work-hours and
require parts costing $1,500, for a cost
of $2,010 per airplane. The FAA has no
way of determining the number of
airplanes that may need these actions.

Proposed AD Requirements in This
NPRM
This proposed AD would require
accomplishing the actions specified in
the service information already
described.
Differences Between This Proposed AD
and the MCAI
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.

Model DA 42, DA 42 M, DA 42 NG, and DA 42 M-NG airplanes. The MCAI
states:
An occurrence was reported of a failed NLG actuator attachment
lever, resulting in disconnection from the NLG leg. When the landing
gear (LG) was retracted, the NLG actuator interfered with the rudder
control rods, forcing the rudder into left-hand deflection. After
lowering the LG, full rudder control was restored. The investigation
results showed that the actuator lever failed due to a crack that
had developed over a longer time period.
This condition, if not detected and corrected, could lead to
restricted rudder travel in LG retracted configuration, possibly
resulting in reduced control of the aeroplane.
To address this potential unsafe condition, [Diamond Aircraft
Industries] DAI issued the applicable [mandatory service bulletin]
MSB, providing instructions to inspect the affected part.
For the reason described above, this [EASA] AD requires
repetitive inspections of the NLG leg actuator attachment lever and,
depending on findings, replacement of the NLG leg.

0602.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Diamond Aircraft Industries Work Instruction WI-
MSB 42-136 and WI-MSB 42NG-078, Revision 1, dated January 24, 2019
(published as one document with Mandatory Service Bulletin MSB 42-136/1
and MSB 42NG-078, dated January 24, 2019). This service information
provides instructions for repetitively inspecting the NLG actuator
attachment lever with replacement of the NLG leg assembly as necessary.
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.
FAA's Determination
This product has been approved by the aviation authority of another
country and is approved for operation in the United States. Pursuant to
the FAA's bilateral agreement with this State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI and
service information referenced above. The FAA is issuing this NPRM
after determining the unsafe condition described previously is likely
to exist or develop on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in the service information already described.
Differences Between This Proposed AD and the MCAI
The MCAI applies to Models DA 42, DA 42 M, DA 42 NG, and DA 42 M-NG
airplanes. This proposed AD would not apply to the Model DA 42 M
because they do not have an FAA type certificate.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 40 airplanes of U.S. registry. The FAA also estimates that it
would take about 1 work-hour per airplane to comply with the inspection
requirement of this proposed AD, and no parts would be necessary. Based
on these figures, the FAA estimates the cost of the inspection for U.S.
operators to be $3,400, or $85 per airplane.
In addition, the FAA estimates that any necessary replacement
actions would take about 6 work-hours and require parts costing $1,500,
for a cost of $2,010 per airplane. The FAA has no way of determining
the number of airplanes 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
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 above, I certify this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
