AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain

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 certain Continental Aerospace 

Technologies, Inc. (Type Certificate 

previously held by Continental Motors, 

Inc., and Teledyne Continental Motors)

TSIO–520–C, TSIO–520–CE, TSIO–520–

engines; and Continental Motors (Type 

Certificate previously held by Teledyne 

Continental Motors) IO–520–A, IO–520– 

B, IO–520–BA, IO–520–BB, IO–520–C, 

IO–520–D, IO–520–J, and IO–520–L 

model reciprocating engines. The NPRM 

published in the Federal Register on 

October 12, 2021 (86 FR 56658). The 

NPRM was prompted by reports of two 

accidents that were the result of power 

loss due to oil starvation. The first was 

a fatal accident on May 1, 2019, in Mill 

Creek California, involving a Cessna 

182P airplane with an installed 

Continental Motors O–470–S engine. 

The National Transportation Safety 

Board’s preliminary accident 

investigation report, docket number 

WPR19FA126, identified evidence of 

improperly maintained or installed oil 

filter adapters. An improperly 

maintained or installed oil filter adapter 

may lead to failure of the fiber gasket, 

which may result in oil loss or oil 

starvation. Based on the investigation, 

the manufacturer determined the need 

to replace the fiber gasket with a copper 

gasket. In the NPRM, the FAA proposed 

to require removal of the fiber gasket 

and replacement with a copper gasket.

9436 Federal Register / Vol. 87, No. 35 / Tuesday, February 22, 2022 / Rules and Regulations 

The FAA is issuing this AD to address 

the unsafe condition on these products. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

two individual commenters. The 

following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. 

Request To Broaden the Scope 

One commenter compared the NPRM 

to a previous AD that the FAA issued 

in 1996, AD 96–12–22 (61 FR 30501, 

June 17, 1996), to address loose or 

separated oil filter adapters. The 

commenter requested that the FAA 

consider issuing an AD with a broader 

scope, such as a remote-mounted oil 

filter secured to the firewall, as a more 

permanent solution. The commenter 

reasoned that a remote-mounted filter 

would reduce the potential for accidents 

caused by oil starvation and power loss. 

The FAA issued AD 96–12–22 to 

address an unsafe condition caused by 

adapter-to-oil pump threads 

fragmenting, resulting in loose or 

separated oil filter adapters. Like AD 

96–12–22, a remote-mounted oil filter 

secured to the firewall is not needed to 

correct the unsafe condition prompting 

this AD, which is power loss due to oil 

starvation. The unsafe condition that 

prompted this AD was caused by failure 

of the fiber gasket due to improperly 

maintained or installed oil filter 

adapters. Therefore, this AD requires 

replacing the fiber gasket with a copper 

gasket. 

Suggestion To Design a Better Gasket 

One commenter requested that the 

FAA make the manufacturer design a 

better gasket, installed with a torque 

commensurate with the torqued 

material, such as fiber gasket material 

similar to the gaskets used in propeller 

governors. The commenter stated that 

the gaskets used in propeller governors 

are manufactured with an oil-resistant 

outer layer, a stainless steel mesh center 

layer, and an oil-resistant inner layer. 

The commenter reasoned that these 

gaskets would cover the entire sealing 

faces of the oil filter adapter and the oil 

pump, unlike the copper gasket, which 

uses only a portion of the sealing area. 

The FAA does not agree that using 

fiber gasket material similar to the 

gaskets used in propeller governors is 

necessary to address the unsafe 

condition, which is power loss due to 

oil starvation. The unsafe condition that 

prompted this AD was caused by failure 

of the fiber gasket due to improperly 

maintained or installed oil filter 

adapters, not the amount of torque 

applied to a specific gasket material. 

Additionally, as part of the certification 

process, the manufacturer has analyzed 

and tested the copper gasket and found 

it meets the design intent. 

Conclusion 

The FAA reviewed the relevant data, 

considered any comments received, 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 Stratus Tool 

Technologies Mandatory Service 

Bulletin (MSB) SB–001 Rev B, dated 

June 17, 2021. This MSB specifies 

procedures for removing a fiber gasket 

and replacing it with a copper gasket. 

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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 6,300 engines installed on 

airplanes of U.S. registry. 

The FAA estimates the following 

costs to comply with this AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Replace fiber gasket with copper gasket ....... 2.5 work-hours × $85 per hour = $212.50 ..... $34 $246.50 $1,552,950 

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.

Airworthiness Directives; DG 

Flugzeugbau GmbH and SchemppHirth Flugzeugbau GmbH Gliders 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for 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 installed. This 

AD was prompted by mandatory 

continuing airworthiness information 

(MCAI) issued by the aviation authority 

of another country to identify and 

correct an unsafe condition on an 

aviation product. The MCAI describes 

the unsafe condition as failure of the 

bearing of the upper pulley of the belt 

driven reduction gear resulting in 

separation of the propeller from the 

engine. This AD requires replacing a 

certain hex-nut and establishing a life 

limit for the ball bearing assembly. The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

DATES: This AD is effective March 29, 

2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of March 29, 2022.
