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 NPRM 

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 NPRM, 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 

NPRM. Submissions containing CBI 

should be sent to Aziz Ahmed, 

Aerospace Engineer, FAA, New York 

ACO Branch, 1600 Stewart Avenue, 

Suite 410, Westbury, New York 11590. 

Any commentary that the FAA receives 

which is not specifically designated as 

CBI will be placed in the public docket 

for this rulemaking. 

Background 

The FAA issued an NPRM (87 FR 

7065, February 8, 2022) that would 

apply to all Viking Air Limited (Viking) 

Model DHC–2 Mk. I, DHC–2 Mk. II, and 

DHC–2 Mk. III airplanes. The NPRM 

proposed to supersede Airworthiness 

Directive (AD) 64–09–03, Amendment 

718 (29 FR 5390; April 22, 1964) (AD 

64–09–03), which applies to all de 

Havilland (type certificate now held by 

Viking) Model DHC–2 ‘‘Beaver’’ 

airplanes. AD 64–09–03 requires 

inspecting the aileron mass balance 

weight arms for cracks and corrosion 

and replacing any damaged part. 

The NPRM proposed to require 

establishing a corrosion prevention and 

control program to identify and correct 

corrosion. 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. The NPRM was 

prompted by mandatory continued 

airworthiness information (MCAI) 

issued by Transport Canada, which is 

the airworthiness authority for Canada. 

Corrosion-related degradation, if not 

addressed, could lead to structural

Federal Register / Vol. 87, No. 34 / Friday, February 18, 2022 / Proposed Rules 9275 

failure with consequent loss of control 

of the airplane. 

Need for the Correction 

As published, the docket number 

referenced throughout the NPRM is 

incorrect. The NPRM incorrectly 

references ‘‘Docket No. FAA–2020– 

7071’’ instead of ‘‘Docket No. FAA– 

2022–0190.’’ 

Although no other part of the 

preamble or regulatory information has 

been corrected, for clarity, the FAA is 

publishing the entire proposed rule in 

the Federal Register. 

The comment due date of the NPRM 

remains March 25, 2022. 

Related Service Information 

The FAA reviewed Viking DHC–2 

Beaver Service Bulletin V2/0011, 

Revision NC, dated November 28, 2019. 

This service information provides a list 

of new inspection tasks that have been 

added to the DHC–2 supplementary 

inspection and corrosion control 

program, Viking Product Support 

Manual (PSM) 1–2–5 DHC–2 Beaver 

Supplemental Inspection and Corrosion 

Control Manual, Revision 1, dated 

January 10, 2019 (Viking PSM–1–2–5, 

Revision 1). 

The FAA also reviewed Viking PSM– 

1–2–5, Revision 1, which specifies 

procedures for inspecting areas of the 

airplane that are particularly susceptible 

to corrosion-related degradation. Viking 

PSM 1–2–5, Revision 1 also specifies 

repetitive inspection intervals, defines 

the different levels of corrosion, and 

provides corrective action if corrosion is 

found. 

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 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 

is issuing this NPRM after determining 

that the unsafe condition described 

previously is likely to exist or develop 

on other products of the same type 

design. 

Proposed AD Requirements 

This proposed AD would retain none 

of the requirements of AD 64–09–03. 

This proposed AD would require 

establishing a corrosion prevention and 

control program approved by the FAA, 

including initial inspection tasks to 

identify corrosion and cracking, 

repetitive inspection intervals, and 

corrective actions (such as repairs and 

application of corrosion inhibitors) if 

corrosion or cracking is found. This 

proposed AD would also require, before 

further flight after establishing the 

program, completing all of the initial 

tasks identified in the program. Lastly, 

this proposed AD would require 

reporting corrosion findings to Viking. 

Because the program would include the 

inspection of the aileron balance weight 

arms required by AD 64–09–03, this 

proposed AD would supersede AD 64– 

09–03. 

ADs Mandating Airworthiness 

Limitations 

The FAA has previously mandated 

airworthiness limitations by issuing 

ADs that require revising the 

airworthiness limitation section (ALS) 

of the existing maintenance manual or 

instructions for continued airworthiness 

to incorporate new or revised 

inspections. This proposed AD, 

however, would require establishing 

and incorporating new inspections into 

the 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 maintenance 

records, rather than requiring individual 

repetitive inspections and replacements, 

allows operators to record AD 

compliance once after updating the 

maintenance records, rather than 

recording compliance after every 

inspection and part replacement. 

Differences Between This Proposed AD 

and the MCAI 

The MCAI requires completing the 

actions as specified in Viking PSM–1– 

2–5. Revision 1. This proposed AD 

would not require Viking PSM–1–2–5, 

Revision 1, but would require 

establishing a corrosion prevention and 

control program using an FAA-approved 

method. However, the FAA considers 

Viking PSM 1–2–5, Revision 1 an 

approved method. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 135 

airplanes of U.S. registry. The FAA also 

estimates that it would take about 342 

work-hours per airplane to establish a 

corrosion prevention and control 

program and comply with the initial 

inspection tasks of the program. 

Based on these figures, the FAA 

estimates the cost of this proposed AD 

on U.S. operators to be $3,924,450 or 

$29,070 per airplane. 

The FAA estimates it would take 

about 1-work hour to report any 

corrosion found during the proposed 

initial inspections, for an estimated cost 

of $85 per airplane. 

The extent of damage found during 

the proposed initial inspections may 

vary significantly from airplane to 

airplane. The FAA has no way to 

determine the estimated cost of repair or 

replacement of damaged parts for each 

airplane or how many airplanes may 

need these repairs or replacements. 

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 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.

9276 Federal Register / Vol. 87, No. 34 / Friday, February 18, 2022 / Proposed Rules 

Regulatory Findings 

The FAA determined that this 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed AD would 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 the proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Would not affect intrastate 

aviation in Alaska, and 

(3) Would not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

Correction 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows:
