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.
