AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

Viking Air Limited (Viking) (type 

certificate previously held by 

Bombardier Inc. and de Havilland, Inc.) 

Model DHC–3 airplanes. This AD 

results from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as corrosion, wear, and 

fatigue-related degradation in aging 

aircraft. This AD requires incorporating 

into the existing maintenance records 

for your airplane the actions and 

associated thresholds and intervals, 

including life limits, specified in a 

supplemental inspection and corrosion 

control manual for Model DHC–3 

airplanes. This AD also requires 

completing all the initial tasks 

identified in this manual and reporting 

corrosion findings to Viking. The FAA 

is issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective October 24, 

2023. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of October 24, 2023.

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 all Viking Model DHC–3 

airplanes. The NPRM published in the 

Federal Register on February 8, 2022 

(87 FR 7059). The NPRM was prompted 

by AD CF–2018–04, dated January 19, 

2018, issued by Transport Canada, 

which is the aviation authority for 

Canada (referred to after this as the 

MCAI). The MCAI states that Viking 

developed a supplementary inspection 

and corrosion control program for aging 

airplanes, which identifies specific 

locations of an airplane that must be 

inspected to ensure corrosion-related 

degradation does not result in an unsafe 

condition. 

The MCAI requires doing all 

inspections specified in Part 2 of Viking 

DHC–3 Otter Supplemental Inspection 

and Corrosion Control Manual, PSM 1– 

3–5, Revision IR, dated December 21, 

2017 (Viking PSM 1–3–5, Revision IR), 

doing applicable corrective actions 

using Part 3 of Viking PSM 1–3–5, 

Revision IR, and reporting to Viking 

Level 2 and Level 3 corrosion as 

specified in Part 3 of Viking PSM 1–3– 

5, Revision IR. 

Corrosion, wear, and fatigue-related 

degradation, if not addressed, could 

lead to structural failure with 

consequent loss of control of the 

airplane. 

In the NPRM, the FAA proposed to 

require establishing a corrosion 

prevention and control program to 

identify and correct corrosion and 

cracking. In the NPRM, the FAA also 

proposed to require completing all of 

the initial tasks identified in the 

program and reporting corrosion 

findings to Viking. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2020–1076. 

The FAA issued a supplemental 

notice of proposed rulemaking (SNPRM) 

to amend 14 CFR part 39 by adding an 

AD that would apply to all Viking 

Model DHC–3 airplanes. The SNPRM 

published in the Federal Register on 

June 28, 2023 (88 FR 41863). The 

SNPRM was prompted by the FAA’s 

decision to revise the proposed actions 

specified in the NPRM and to reopen 

the comment period to allow the public 

the chance to comment on whether the 

proposed AD would have a significant 

economic impact on a substantial 

number of small entities. In the SNPRM, 

the FAA proposed to require 

incorporating into the existing 

maintenance records for your airplane 

the actions and associated thresholds 

and intervals, including life limits, 

specified in Parts 2 and 3 of Viking PSM 

1–3–5, Revision IR, completing all the 

initial tasks identified in Viking PSM 1– 

3–5, Revision IR, and reporting to 

Viking any Level 2 or Level 3 corrosion 

findings. The FAA is issuing this AD to 

address the unsafe condition on these 

products. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the SNPRM or on the determination of 

the costs. 

Conclusion 

These products have been approved 

by the aviation authority of another 

country and are 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. Except for minor editorial 

changes, this AD is adopted as proposed 

in the SNPRM. 

ADs Mandating Airworthiness 

Limitations (ALS) 

The FAA has previously mandated 

airworthiness limitations by issuing 

ADs that require revising the ALS of the 

existing maintenance manual or 

instructions for continued airworthiness 

to incorporate new or revised 

inspections. This AD, however, requires 

establishing and incorporating new 

inspections into the existing 

maintenance records required by 14 

CFR 91.417(a)(2) or 135.439(a)(2) for 

your airplane. The FAA does not intend 

this as a substantive change. Requiring 

incorporation of the new ALS 

requirements into the existing 

maintenance records, rather than 

requiring individual repetitive 

inspections and replacements, allows 

operators to record AD compliance once 

after updating the existing maintenance 

records, rather than recording 

compliance after every inspection and 

part replacement. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Viking PSM 1–3– 

5, Revision IR, which specifies 

procedures for inspecting areas of the 

airplane that are particularly susceptible 

to corrosion, wear, and fatigue-related 

degradation. Viking PSM 1–3–5, 

Revision IR, also specifies repetitive 

inspection intervals, defines the 

different levels of corrosion, and 

provides corrective action if corrosion is 

found. 

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. 

Other Related Service Information 

The FAA also reviewed Viking DHC– 

3 Otter Service Bulletin V3/0010, 

Revision NC, dated March 19, 2020. The 

service bulletin provides a list of new 

inspection tasks that have been added to 

the DHC–3 maintenance program in 

Viking PSM 1–3–5, Revision IR. 

Impact on Intrastate Aviation in Alaska 

In light of the heavy reliance on 

aviation for intrastate transportation in 

Alaska, the FAA has fully considered 

the effects of this final rule (including 

costs to be borne by affected operators) 

from the earliest possible stages of AD 

development. As previously stated, 14 

CFR part 39 requires operators to correct 

an unsafe condition identified on an 

airplane to ensure operation of that 

airplane in an airworthy condition. The 

FAA has determined that the need to 

correct corrosion-related degradation in 

aging aircraft, which could lead to 

structural failure with consequent loss 

of control of the airplane, outweighs any 

impact on aviation in Alaska. 

Costs of Compliance 

The FAA estimates that this AD 

affects 68 airplanes of U.S. registry. The 

FAA also estimates that it will take 

about 1 work-hour per airplane at a

labor rate of $85 per work-hour to revise 

the existing maintenance records. 

Based on these figures, the FAA 

estimates the cost of this AD on U.S. 

operators to be $5,780 or $85 per 

airplane. 

The FAA estimates it will take about 

1 work-hour to report any Level 2 

corrosion found during the initial or 

subsequent inspections or any Level 3 

corrosion found during the initial or 

subsequent inspections, for an estimated 

cost of $85 per airplane. 

Paperwork Reduction Act 

A federal agency may not conduct or 

sponsor, and a person is not required to 

respond to, nor shall a person be subject 

to a penalty for failure to comply with 

a collection of information subject to the 

requirements of the Paperwork 

Reduction Act unless that collection of 

information displays a currently valid 

OMB Control Number. The OMB 

Control Number for this information 

collection is 2120–0056. Public 

reporting for this collection of 

information is estimated to take 

approximately 1 hour per response, 

including the time for reviewing 

instructions, searching existing data 

sources, gathering and maintaining the 

data needed, and completing and 

reviewing the collection of information. 

All responses to this collection of 

information are mandatory. Send 

comments regarding this burden 

estimate or any other aspect of this 

collection of information, including 

suggestions for reducing this burden, to:

Administration, 10101 Hillwood 

Parkway, Fort Worth, TX 76177–1524. 

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 Flexibility Determination 

The Regulatory Flexibility Act of 

1980, Public Law 96–354, 94 Stat. 1164 

(5 U.S.C. 601–612) (RFA) establishes as 

a principle of regulatory issuance that 

agencies shall endeavor, consistent with 

the objectives of the rule and of 

applicable statutes, to fit regulatory and 

informational requirements to the scale 

of the businesses, organizations, and 

governmental jurisdictions subject to 

regulation. 

To achieve this principle, agencies are 

required to solicit and consider flexible 

regulatory proposals and to explain the 

rationale for their actions to assure that 

such proposals are given serious 

consideration. The RFA covers a widerange of small entities, including small 

businesses, not-for-profit organizations, 

and small governmental jurisdictions. 

Agencies must perform a review to 

determine whether a rule will have a 

significant economic impact on a 

substantial number of small entities. If 

the agency determines that it will, the 

agency must prepare a regulatory 

flexibility analysis as described in the 

RFA. 

The FAA published an Initial 

Regulatory Flexibility Analysis (IRFA) 

for this rule to aid the public in 

commenting on the potential impacts to 

small entities. The FAA did not receive 

any public comments on the IRFA. The 

purpose of this Final Regulatory 

Flexibility Analysis (FRFA) is to 

provide the reasoning underlying the 

FAA’s determination. A FRFA must 

contain the following: 

(1) A statement of the need for, and 

objectives of, the rule; 

(2) A statement of the significant 

issues raised by the public comments in 

response to the IRFA, a statement of the 

assessment of the agency of such issues, 

and a statement of any changes made in 

the proposed rule as a result of such 

comments; 

(3) The response of the agency to any 

comments filed by the Chief Counsel for 

Advocacy of the Small Business 

Administration (SBA) in response to the 

proposed rule, and a detailed statement 

of any change made to the proposed rule 

in the final rule as a result of the 

comments; 

(4) A description of and an estimate 

of the number of small entities to which 

the rule will apply or an explanation of 

why no such estimate is available; 

(5) A description of the projected 

reporting, recordkeeping, and other 

compliance requirements of the 

proposed rule, including an estimate of 

the classes of small entities which will 

be subject to the requirement and the 

type of professional skills necessary for 

preparation of the report or record; and 

(6) A description of the steps the 

agency has taken to minimize the 

significant economic impact on small 

entities consistent with the stated 

objectives of applicable statutes, 

including a statement of the factual, 

policy, and legal reasons for selecting 

the alternative adopted in the final rule 

and why each of the other significant 

alternatives to the rule considered by 

the agency which affect the impact on 

small entities was rejected. 

1. Need for and Objectives of the Rule 

The NPRM proposed to adopt a new 

AD for all Viking Model DHC–3 

airplanes. This AD results from MCAI 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. 

The objective of this final rule is to 

require incorporating into the existing 

maintenance records for your airplane 

the actions and associated thresholds 

and intervals, including life limits, 

specified in a supplemental inspection 

and corrosion control manual for Model 

DHC–3 airplanes. This final rule also 

requires completing all the initial tasks 

identified in this manual and reporting 

corrosion findings to Viking. 

2. Significant Issues Raised in Public 

Comments 

The FAA received no public 

comments on the SNPRM. 

3. Response to SBA Comments 

The Chief Counsel for Advocacy of 

the SBA did not file any comments in 

response to the proposed rule. Thus, the 

FAA did not make any changes to the 

proposed rule in the final rule. 

4. Description and Estimate of the 

Number of Small Entities 

The RFA defines small entities as 

small businesses, small governmental 

jurisdictions, or small organizations. In 

5 U.S.C. 601(3), the RFA defines ‘‘small 

business’’ to have the same meaning as 

‘‘small business concern’’ under section 

3 of the Small Business Act. The Small 

Business Act authorizes the SBA to 

define ‘‘small business’’ by issuing 

regulations. 

SBA (2022) has established size 

standards for various types of economic 

activities, or industries, under the North 

American Industry Classification 

System (NAICS).1 These size standards 

generally define small businesses based

on the number of employees or annual 

receipts. 

The FAA identified 68 de Havilland 

Model DHC–3 ‘‘Otter’’ airplanes that 

would be affected by the final rule AD. 

These 68 airplanes are registered to 32 

private firms and 5 individuals. The 

individuals are excluded from this 

analysis as they presumably are not 

small entities under the RFA. 

The 32 private firms own 63 

airplanes. Of these firms, the FAA was 

able to obtain the data necessary to 

classify 21 of them.2 All but one firm 

qualify as small entities under the RFA. 

Thus, the FAA estimates that this rule 

would impact 20 small entities. For 

these 20 small entities, the results of the 

cost impact analysis are shown in Table 

1, ‘‘Cost Impact on Small Entities.’’ 

5. Projected Reporting, Recordkeeping, 

and Other Compliance Requirements 

AD costs per airplane are 1 work hour 

plus $85 reporting costs for initial 

inspection, for a total of $170. The AD 

cost per small entity is shown in the 

‘‘Cost’’ column of Table 1 and cost 

impact is measured by AD cost as a 

percentage of revenues. As the table 

shows, the mean cost impact is 0.1% of 

annual revenues, with a maximum 

impact of 0.46% of annual revenues, 

and a minimum impact below 0.01%.

Notes: 1. The size standard is the maximum size for the NAICS industry considered by the Small Business Administration to be a small entity. 2. AD costs per airplane are 1 work-hour × $85 + $85 reporting costs for initial inspection, for a total of $170. 

Costs under 1% of revenues for all of 

the small entities lead the FAA to 

conclude that this rule does not have a 

significant impact on a substantial 

number of small entities. 

6. Significant Alternatives Considered 

As part of the FRFA, the FAA is 

required to consider regulatory 

alternatives that may be less 

burdensome. 

The FAA did not find any significant 

regulatory alternatives to this AD that 

would still accomplish the safety 

objectives of this AD. 

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, 

and 

(2) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the RFA.

64372 Federal Register / Vol. 88, No. 180 / Tuesday, September 19, 2023 / Rules and Regulations 

The Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive: 

2023–18–03 Viking Air Limited (Type 

Certificate Previously Held by 

Bombardier Inc. and de Havilland, Inc.): 

Amendment 39–22544; Docket No. 

FAA–2020–1076; Project Identifier 

MCAI–2020–01201–A. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective October 24, 2023. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Viking Air Limited 

(type certificate previously held by 

Bombardier Inc. and de Havilland, Inc.) 

Model DHC–3 airplanes, all serial numbers, 

certificated in any category. 

(d) Subject 

Joint Aircraft System Component (JASC) 

Code 2700, Flight Control System. 

(e) Unsafe Condition 

This AD was prompted by mandatory 

continuing airworthiness information (MCAI) 

originated by an aviation authority of another 

country to identify and correct an unsafe 

condition on an aviation product. The MCAI 

describes the unsafe condition as corrosion, 

wear, and fatigue-related degradation in 

aging aircraft. The FAA is issuing this AD to 

detect and address corrosion and cracking. 

This condition, if not addressed, could lead 

to structural failure with consequent loss of 

control of the airplane. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

(1) Within 90 days after the effective date 

of this AD, incorporate into the existing 

maintenance records required by 14 CFR 

91.417(a)(2) or 135.439(a)(2), as applicable 

for your airplane, the actions and associated 

thresholds and intervals, including life 

limits, specified in Parts 2 and 3 of Viking 

DHC–3 Otter Supplemental Inspection and 

Corrosion Control Manual, PSM 1–3–5, 

Revision IR, dated December 21, 2017 

(Viking PSM 1–3–5, Revision IR). Do each 

initial task within 6 months after the effective 

date of this AD or at the threshold for each 

applicable task specified in Part 3 of Viking 

Product Support Manual PSM 1–3–5, 

Revision IR, whichever occurs later. Where 

Viking PSM 1–3–5, Revision IR, specifies 

contacting Viking regarding a component’s 

alloy and heat treat condition, this AD 

requires contacting the Manager, 

International Validation Branch, FAA, 

Transport Canada, or Viking’s Transport 

Canada Design Approval Organization 

(DAO). If approved by the DAO, the approval 

must include the DAO-authorized signature.

(g)(1) of this AD has been done, no 

alternative actions and associated thresholds 

and intervals, including life limits, are 

allowed unless they are approved as 

specified in paragraph (i) of this AD. 

(h) Reporting 

(1) For inspections done after the effective 

date of this AD, report to Viking any Level 

2 or Level 3 corrosion, as specified in Viking 

PSM 1–3–5, Revision IR, at the times 

specified in and in accordance with part 3, 

paragraph 5, of Viking PSM 1–3–5, Revision 

IR. 

(2) For inspections done before the 

effective date of this AD, within 30 days after 

the effective date of this AD report to Viking
