SUPPLEMENTARY INFORMATION: 

Background 

Transport Canada Civil Aviation 

(TCCA) which is the aviation authority 

for Canada, has issued TCCA AD CF– 

2022–12, dated March 21, 2022 (referred 

to after this as the Mandatory 

Continuing Airworthiness Information, 

or the MCAI), to correct an unsafe 

condition for certain De Havilland 

Aircraft of Canada Limited Model DHC– 

8–401 and –402 airplanes. You may 

examine the MCAI on the internet at 

https://www.regulations.gov by 

searching for and locating Docket No. 

FAA–2022–0593. 

This AD was prompted by reports that 

following a MLG extension, one of the 

MLGs could not be locked in the gear 

down position due to deterioration of 

greasing effectiveness over time. The 

deterioration of grease affects the MLG 

assembly, including the lock actuator 

assembly, stabilizer brace to nacelle 

structure attachment, downlock 

assembly, stabilizer brace pivot, 

stabilizer brace to yoke attachment and 

retractor actuator lug end. An increase 

in friction within the MLG assembly 

(mechanism) could lead to failure to 

achieve an MLG down and locked 

condition. The FAA is issuing this AD 

to address this condition, which could 

result in a MLG collapse upon landing 

and consequently could cause the wing 

of the airplane to make contact with the 

ground and cause the airplane to flip. 

See the MCAI for additional background 

information. 

Related Service Information Under 1 

CFR Part 51 

De Havilland Aircraft of Canada 

Limited has issued Service Bulletin 84– 

32–168, Revision A, dated February 8, 

2022. This service information describes 

procedures for repetitive lubrication of 

the MLG assembly, which includes the 

lock actuator assembly, stabilizer brace 

to nacelle structure attachment, 

downlock assembly, stabilizer brace 

pivot, stabilizer brace to yoke 

attachment and retractor actuator lug 

end. 

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 the State 

of Design Authority, the FAA has been 

notified of the unsafe condition 

described in the MCAI and service 

information referenced above. The FAA 

is issuing this AD because the FAA 

evaluated all pertinent information and 

determined the unsafe condition exists 

and is likely to exist or develop on other 

products of the same type design. 

Requirements of This AD 

This AD requires accomplishing the 

actions specified in the service 

information described previously, 

except as discussed under ‘‘Differences 

Between this AD and the MCAI or 

Service Information.’’ 

Differences Between This AD and 

Service Information 

Paragraph 3.B. of the 

Accomplishment Instructions of De 

Havilland Aircraft of Canada Limited 

Service Bulletin 84–32–168, Revision A, 

dated February 8, 2022, specifies to do 

a review of the maintenance records to 

verify the elapsed time from the last 

greasing operation on the MLG; and for 

airplanes on which it has been over 3 

months since the last greasing, perform 

greasing on the MLG assembly. 

However, this AD requires lubricating 

the MLG assembly within 500 flight 

hours or 3 months, whichever occurs 


lotter on DSK11XQN23PROD with RULES1
34130 Federal Register / Vol. 87, No. 108 / Monday, June 6, 2022 / Rules and Regulations 

first after the effective date of this AD 

and thereafter at intervals not to exceed 

500 flight hours or 3 months, whichever 

occurs first. 

FAA’s Justification and Determination 

of the Effective Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD without providing an opportunity 

for public comments prior to adoption. 

The FAA has found that the risk to the 

flying public justifies waiving notice 

and comment prior to adoption of this 

rule because the FAA received reports 

that following a MLG extension, one of 

the MLGs could not be locked in the 

gear down position due to deterioration 

of greasing effectiveness over time. The 

deterioration of grease affects the MLG 

assembly, including the lock actuator 

assembly, stabilizer brace to nacelle 

structure attachment, downlock 

assembly, stabilizer brace pivot, 

stabilizer brace to yoke attachment and 

retractor actuator lug end. An increase 

in friction within the MLG assembly 

(mechanism) could lead to failure to 

achieve an MLG down and locked 

condition and result in an MLG collapse 

upon landing. For certain Model DHC– 

8–401 and –402 airplanes, a MLG 

collapse could cause the wing of the 

airplane to make contact with the 

ground as the wing on the collapsed 

MLG side may dig in to the runway and 

cause the airplane to flip. Therefore, the 

FAA finds good cause that notice and 

opportunity for prior public comment 

are impracticable. In addition, for the 

reasons stated above, the FAA finds that 

good cause exists for making this 

amendment effective in less than 30 

days. 

Comments Invited 

The FAA invites you to send any 

written relevant data, views, or 

arguments about this AD. Send your 

comments to an address listed under 

ADDRESSES. Include ‘‘Docket No. FAA– 

2022–0593; Project Identifier MCAI– 

2022–00408–T’’ at the beginning of your 

comments. The most helpful comments 

reference a specific portion of the final 

rule, explain the reason for any 

recommended change, and include 

supporting data. The FAA will consider 

all comments received by the closing 

date and may amend this final rule 

because of those comments. 

Except for Confidential Business 

Information (CBI) as described in the 

following paragraph, and other 

information as described in 14 CFR 

11.35, the FAA will post all comments 

received, without change, to https://

www.regulations.gov, including any 

personal information you provide. The 

agency will also post a report 

summarizing each substantive verbal 

contact received about this final rule. 

Confidential Business Information 

CBI is commercial or financial 

information that is both customarily and 

actually treated as private by its owner. 

Under the Freedom of Information Act 

(FOIA) (5 U.S.C. 552), CBI is exempt 

from public disclosure. If your 

comments responsive to this AD contain 

commercial or financial information 

that is customarily treated as private, 

that you actually treat as private, and 

that is relevant or responsive to this AD, 

it is important that you clearly designate 

the submitted comments as CBI. Please 

mark each page of your submission 

containing CBI as ‘‘PROPIN.’’ The FAA 

will treat such marked submissions as 

confidential under the FOIA, and they 

will not be placed in the public docket 

of this AD. Submissions containing CBI 

should be sent to Elizabeth Dowling, 

Aerospace Engineer, Mechanical 

Systems and Administrative Services 

Section, FAA, New York ACO Branch, 

1600 Stewart Avenue, Suite 410, 

Westbury, NY 11590; telephone 516– 

228–7300; email 9-avs-nyaco-cos@

faa.gov. Any commentary that the FAA 

receives which is not specifically 

designated as CBI will be placed in the 

public docket for this rulemaking. 

Regulatory Flexibility Act (RFA) 

The requirements of the RFA do not 

apply when an agency finds good cause 

pursuant to 5 U.S.C. 553 to adopt a rule 

without prior notice and comment. 

Because the FAA has determined that it 

has good cause to adopt this rule 

without notice and comment, RFA 

analysis is not required. 

Costs of Compliance 

The FAA estimates that this AD 

affects 41 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on 

U.S. operators 

2 work-hour × $85 per hour = $170 ............................................................................................ $0 $170 $6,970 

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 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, 

and 

(2) Will not affect intrastate aviation 

in Alaska.

Export Administration Regulations: 

Revisions to Russia and Belarus 

Sanctions and Related Provisions; 

Other Revisions, Corrections, and 

Clarifications 

AGENCY: Bureau of Industry and 

Security, Department of Commerce. 

ACTION: Final rule. 

SUMMARY: Between February and May 

2022, the Bureau of Industry and 

Security (BIS) has published a series of 

amendments to the Export 

Administration Regulations (EAR) that 

have increasingly tightened export 

controls on the Russian Federation 

(Russia) and Belarus in response to 

Russia’s further invasion of Ukraine, as 

substantially enabled by Belarus. This 

rule revises, corrects, and clarifies 

certain provisions of the EAR that 

pertain to these controls and related 

provisions. First, this rule makes certain 

revisions to the EAR’s military end use 

and military end user controls as they 

apply to Russia and Belarus, as well as 

related modifications to the entries for 

entities on the Entity List that are 

Russian and Belarusian military end 

users. Second, it revises restrictions that 

apply to items destined for certain 

regions in Ukraine by clarifying the
