SUPPLEMENTARY INFORMATION:
Comments
The FAA received no comments on
the NPRM or on the determination of
the costs.
lotter on DSK11XQN23PROD with RULES1
Background
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to DG Flugzeugbau GmbH Model
DG–1000T gliders and Schempp-Hirth
Flugzeugbau GmbH Model Duo Discus
T gliders with a Solo Kleinmotoren
GmbH Solo Model 2350C or 2350D
engine, all serial numbers, installed.
The NPRM published in the Federal
Register on December 1, 2021 (86 FR
68168). The NPRM was prompted by
MCAI originated by the European
Aviation Safety Agency (EASA), which
is the Technical Agent for the Member
States of the European Union. EASA
issued EASA AD 2019–0029, dated
February 8, 2019 (referred to after this
as ‘‘the MCAI’’), to address an unsafe
condition on Solo Kleinmotoren GmbH
Solo Model 2350B, 2350BS, 2350C, and
2350D engines. The MCAI states:
An occurrence was reported of failure of
the bearing of the upper pulley of the belt
driven reduction gear, resulting in separation
of the propeller from the engine.
This condition, if not corrected, could lead
to similar occurrences, with possible reduced
control of, and damage to, the aircraft.
To address this potential unsafe condition,
Solo redesigned the nut securing the pulley
bearing on the axle and introduced a life time
limit of 15 years for the reduction gear
bearings.
For the reason stated above, this [EASA]
AD requires replacement of affected parts
with serviceable parts, and introduces a life
limit for the affected ball bearings.

Conclusion
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 referenced above. The FAA
reviewed the relevant data and
determined that air safety requires
adopting this AD as proposed.
Accordingly, the FAA is issuing this AD
to address the unsafe condition on these
products. This AD is adopted as
proposed in the NPRM.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Solo Kleinmotoren
GmbH Service Bulletin 4603–18, dated
January 22, 2019. The service
information specifies procedures for
replacing the hex-nut at the excentric
axle and the ball bearing assemblies at
the bearing block of the reduction gear.
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 ADDRESSES.
Differences Between This AD and the
MCAI or Service Information
The MCAI applies to Solo
Kleinmotoren GmbH Solo Model 2350B,
2350BS, 2350C, and 2350D engines.
None of these model engines have an
FAA engine type certificate. However,
Model 2350C and Model 2350D engines
are certificated by the FAA with the
type certificate for certain gliders. This
AD does not apply to Solo Kleinmotoren
GmbH Solo Model 2350B and 2350BS
engines because they are not part of an
FAA glider type design.
The MCAI requires replacing an
affected ball bearing assembly before it
accumulates 15 years since first
installation on an engine. This AD
requires replacing both ball bearing
assemblies simultaneously before either
accumulates 15 years since first
installation on an engine.
Costs of Compliance
The FAA estimates that this AD
affects 10 gliders of U.S. registry. The
FAA estimates that for gliders with an
affected hex-nut, replacement would
PO 00000
Frm 00014
Fmt 4700
Sfmt 4700
take about 0.5 work-hour and require a
part costing $95. The average labor rate
is $85 per work-hour. Based on these
figures, the FAA estimates the cost to
replace the hex-nut on U.S. operators to
be $1,380 (assuming all 10 gliders have
this configuration) or $138 per glider.
In addition, the FAA estimates that
for gliders with the affected ball bearing
assemblies, replacement would take
about 4 work-hours for both ball bearing
assemblies and require ball bearing
assemblies costing $118 (2 units). The
average labor rate is $85 per work-hour.
Based on these figures, the FAA
estimates the cost of the ball bearing
assembly replacement on U.S. operators
to be $4,580 (assuming all 10 gliders
have this configuration) or $458 per
glider.
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 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:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to DG Flugzeugbau GmbH
Model DG-1000T gliders and Schempp-Hirth Flugzeugbau GmbH Model Duo
Discus T gliders with a Solo Kleinmotoren GmbH Solo Model 2350C or
2350D engine, all serial numbers, installed. The NPRM published in the
Federal Register on December 1, 2021 (86 FR 68168). The NPRM was
prompted by MCAI originated by the European Aviation Safety Agency
(EASA), which is the Technical Agent for the Member States of the
European Union. EASA issued EASA AD 2019-0029, dated February 8, 2019
(referred to after this as ``the MCAI''), to address an unsafe
condition on Solo Kleinmotoren GmbH Solo Model 2350B, 2350BS, 2350C,
and 2350D engines. The MCAI states:
An occurrence was reported of failure of the bearing of the
upper pulley of the belt driven reduction gear, resulting in
separation of the propeller from the engine.
This condition, if not corrected, could lead to similar
occurrences, with possible reduced control of, and damage to, the
aircraft.
To address this potential unsafe condition, Solo redesigned the
nut securing the pulley bearing on the axle and introduced a life
time limit of 15 years for the reduction gear bearings.
For the reason stated above, this [EASA] AD requires replacement
of affected parts with serviceable parts, and introduces a life
limit for the affected ball bearings.
You may examine the MCAI in the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-
1015.
Comments
The FAA received no comments on the NPRM or on the determination of
the costs.
Conclusion
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
referenced above. The FAA reviewed the relevant data and determined
that air safety requires adopting this AD as proposed. Accordingly, the
FAA is issuing this AD to address the unsafe condition on these
products. This AD is adopted as proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Solo Kleinmotoren GmbH Service Bulletin 4603-18,
dated January 22, 2019. The service information specifies procedures
for replacing the hex-nut at the excentric axle and the ball bearing
assemblies at the bearing block of the reduction gear. 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 ADDRESSES.
Differences Between This AD and the MCAI or Service Information
The MCAI applies to Solo Kleinmotoren GmbH Solo Model 2350B,
2350BS, 2350C, and 2350D engines. None of these model engines have an
FAA engine type certificate. However, Model 2350C and Model 2350D
engines are certificated by the FAA with the type certificate for
certain gliders. This AD does not apply to Solo Kleinmotoren GmbH Solo
Model 2350B and 2350BS engines because they are not part of an FAA
glider type design.
The MCAI requires replacing an affected ball bearing assembly
before it accumulates 15 years since first installation on an engine.
This AD requires replacing both ball bearing assemblies simultaneously
before either accumulates 15 years since first installation on an
engine.
Costs of Compliance
The FAA estimates that this AD affects 10 gliders of U.S. registry.
The FAA estimates that for gliders with an affected hex-nut,
replacement would take about 0.5 work-hour and require a part costing
$95. The average labor rate is $85 per work-hour. Based on these
figures, the FAA estimates the cost to replace the hex-nut on U.S.
operators to be $1,380 (assuming all 10 gliders have this
configuration) or $138 per glider.
In addition, the FAA estimates that for gliders with the affected
ball bearing assemblies, replacement would take about 4 work-hours for
both ball bearing assemblies and require ball bearing assemblies
costing $118 (2 units). The average labor rate is $85 per work-hour.
Based on these figures, the FAA estimates the cost of the ball bearing
assembly replacement on U.S. operators to be $4,580 (assuming all 10
gliders have this configuration) or $458 per glider.
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 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.
