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 serial-numbered Viking 

Air Limited Model DHC–6–1, DHC–6– 

100, DHC–6–200, DHC–6–300, and 

DHC–6–400 airplanes. The NPRM 

published in the Federal Register on 

March 22, 2022 (87 FR 16123). The 

NPRM was prompted by MCAI 

originated by Transport Canada, which 

is the aviation authority for Canada. 

Transport Canada has issued AD CF– 

2021–42, dated November 26, 2021 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition on Viking 

Air Limited Model DHC–6 series 1, 

DHC–6 series 100, DHC–6 series 110, 

DHC–6 series 200, DHC–6 series 210, 

DHC–6 series 300, DHC–6 series 310, 

DHC–6 series 320, and DHC–6 series 

400 airplanes with certain partnumbered FCU push rod assemblies 

installed. The MCAI states: 

There have been in-service reports of 

binding of [part number] P/N VSC30–3A rod 

end bearings used in the linkage for the lower 

FCU push rod assembly P/N C6CE1398–7. 

The lower FCU push rod assembly is 

connected to the FCU power lever and 

contains a rod end bearing at each end. P/N 

VSC30–3A rod end bearings, fabricated with 

a metal inner race and a dry film lubricant, 

have been incorporated on FCU push rod 

assemblies introduced through Viking Air 

Ltd (Viking) MOD 6/2347. P/N VSC30–3A 

rod end bearings may have also been 

installed in-service as a replacement part in 

lower FCU push rod assembly P/N 

C6CE1398–3. In one instance, binding of the 

lower FCU push rod bearing resulted in one 

engine failing to return to a lower power 

setting from a higher power setting when 

commanded, which subsequently resulted in 

the need to perform an in-flight engine 

shutdown during final approach. An 

investigation also revealed that binding of 

P/N VSC30–3A rod end bearings can occur 

after a period of non-utilization of the 

aeroplane. 

This condition, if not detected and 

corrected, may lead to the inability to reduce 

power on the affected engine, resulting in the 

need to perform an in-flight engine 

shutdown, and consequently leading to 

reduced control of the aeroplane and 

increased pilot workload during this critical 

phase of flight. 

To address this unsafe condition, this 

[Transport Canada] AD mandates initial and 

repetitive functional checks, special detailed 

inspection (SDI) and lubrication of the 

affected FCU push rod assembly, and its 

replacement, as required, with a redesigned 

FCU push rod assembly with improved 

reliability (MOD 6/2484), in accordance with 

Viking Service Bulletin (SB) V6/0063. This 

[Transport Canada] AD also prohibits the 

installation of an affected FCU push rod 

assembly as a replacement part on applicable 

aeroplanes. 

You may examine the MCAI in the 

AD docket at https://

www.regulations.gov by searching for 

and locating Docket No. FAA–2022– 

0284. 

In the NPRM, the FAA proposed to 

require performing tests, inspections, 

and lubrication of the FCU push rod 

assemblies, and replacing them with 

improved parts as necessary. The FAA 

is issuing this AD to address the unsafe 

condition on these products. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received one comment from 

the Air Line Pilots Association, 

International (ALPA). ALPA supported 

the NPRM without change. 

Conclusion 

These products have 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 reviewed 

the relevant data and determined that 

air safety and the public interest require 

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 the following: 

• Viking DHC–6 Twin Otter Service 

Bulletin (SB) No. V6/0063, Revision A, 

dated February 1, 2021, which specifies 

procedures for performing tests, 

inspections, and lubrication of the FCU 

push rod assemblies; and 

• Viking DHC–6 Twin Otter 

Technical Bulletin No. V6/00155, 

Revision NC, dated September 14, 2020, 

which specifies procedures for replacing 

the FCU push rod assemblies with 

improved parts. 

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. 

Other Related Service Information 

The FAA also reviewed Viking DHC– 

6 Twin Otter SB No. V6/0063, Revision 

NC, dated June 7, 2019, which specifies 

procedures for performing tests, 

inspections, and lubrication of the FCU 

push rod assemblies. Viking revised this 

service information and issued Viking 

SB V6/0063, Revision A, to extend the 

lubrication requirement of Mod 6/2347 

rod ends to all operating environments, 

add repeat inspections, and introduce a 

test and lubrication for airplanes that 

have not been in operation after a period 

of time before re-entry into service. 

Differences Between This AD and the 

MCAI 

The MCAI applies to Viking Air 

Limited Model DHC–6 series 110, DHC– 

6 series 210, DHC–6 series 310, and 

DHC–6 series 320, and this AD would 

not because these models do not have 

an FAA type certificate. Model DHC–6 

series 1, DHC–6 series 100, DHC–6 

series 200, DHC–6 series 300, and DHC– 

6 series 400 airplanes specified in the 

MCAI correspond to Model DHC–6–1, 

DHC–6–100, DHC–6–200, DHC–6–300, 

and DHC–6–400 airplanes specified in 

this AD, respectively. 

The MCAI requires reporting 

information to the manufacturer, and 

this AD does not. 

Costs of Compliance 

The FAA estimates that this AD 

affects 34 airplanes of U.S. registry. The 

FAA estimates the following costs to 

comply with this AD:

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.

Extension of Import Restrictions 

Imposed on Certain Archaeological 

Artifacts and Ethnological Material 

From Peru 

AGENCY: U.S. Customs and Border 

Protection, Department of Homeland 

Security; Department of the Treasury. 

ACTION: Final rule. 

SUMMARY: This document amends the 

U.S. Customs and Border Protection 

(CBP) regulations to reflect an extension 

of import restrictions on certain 

categories of archaeological artifacts and 

ethnological material of the Republic of 

Peru. The restrictions, which were 

originally imposed by Treasury Decision 

(T.D.) 97–50 and last extended by CBP 

Decision (CBP Dec.) 17–03, are due to 

expire on June 9, 2022, unless extended. 

The Assistant Secretary for Educational 

and Cultural Affairs, United States 

Department of State, has made the 

requisite determinations for extending 

the import restrictions that previously 

existed and no cause for suspension 

exists. Pursuant to the exchange of 

diplomatic notes to extend the 

agreement, the import restrictions will 

remain in effect for an additional five 

years, and the CBP regulations are being 

amended to reflect this further 

extension through June 8, 2027. CBP– 

Dec. 17–03 contains the Designated List 

of archeological artifacts and 

ethnological material from Peru to 

which the restrictions apply. 

DATES: Effective on June 9, 2022.
