Model DHC–3 airplanes. The MCAI states: Service experience indicates that aging aircraft are more likely to be adversely affected by corrosion, wear and fatigue cracking. Viking Air Limited (Viking), as Type Certificate holder for the DHC–3, has developed a supplementary inspection and corrosion control program which identifies specific areas that must be inspected to ensure that corrosion, wear and fatiguerelated degradation do not result in an unsafe condition. The program is documented in Viking Product Support Manual (PSM) 1–3– 5 DHC–3 Otter Supplementary Inspection and Corrosion Control Manual (SICCM). Corrosion levels are defined in PSM 1–3– 5 as a means for assessing the effectiveness of the corrosion control program and recording the results of the inspections mandated by this [Transport Canada] AD. Each item specified for inspection in PSM 1–3–5 has been substantiated to Transport Canada as having experienced significant degradation in service and, as having the potential to develop into an unsafe condition if the inspections defined in the PSM are not implemented. Corrosion and cracking, if not addressed, could lead to structural failure with consequent loss of control of the airplane. You may examine the VerDate Sep<11>2014 15:47 Feb 07, 2022 Jkt 256001 MCAI at https://www.regulations.gov by searching for and locating Docket No. FAA–2020–1076. Related Service Information The FAA 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 as a supplemental corrosion prevention manual, Viking Product Support Manual (PSM) 1–3–5 DHC–3 Otter Supplemental Inspection and Corrosion Control Manual, Revision IR, dated December 21, 2017 (Viking PSM 1–3–5, Revision IR). The FAA also 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. 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. Requirements of the Proposed AD 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. The 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. ADs Mandating Airworthiness Limitations The FAA has previously mandated airworthiness limitations by issuing ADs that require revising the airworthiness limitation section (ALS) PO 00000 Frm 00013 Fmt 4702 Sfmt 4702 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 Transport Canada AD CF–2018–04 requires completing the actions as specified in Viking PSM 1–3–5, Revision IR. This proposed AD would not require Viking PSM 1–3–5, Revision IR, but would require establishing a corrosion prevention and control program using an FAA-approved method. However, the FAA considers Viking PSM 1–3–5, Revision IR, an approved method. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 38 airplanes of U.S. registry. The FAA also estimates that it would take about 145 work-hours per airplane to establish a corrosion prevention and control program and comply with the initial tasks of the program. Based on these figures, the FAA estimates the cost of the proposed AD on U.S. operators to be $468,350 or $12,325 per airplane. The FAA estimates it would take about 1work-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. 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 E:\FR\FM\08FEP1.SGM 08FEP1 Federal Register / Vol. 87, No. 26 / Tuesday, February 8, 2022 / Proposed Rules 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: Information Collection Clearance Officer, Federal Aviation 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. khammond on DSKJM1Z7X2PROD with PROPOSALS 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 this 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 VerDate Sep<11>2014 15:47 Feb 07, 2022 Jkt 256001 under the criteria of the Regulatory Flexibility Act.

Airworthiness Directives; Viking Air Limited (Type Certificate 
Previously Held by Bombardier Inc. and de Havilland, Inc.) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for Viking Air Limited (Viking) (type certificate previously held by 
Bombardier Inc. and de Havilland, Inc.) Model DHC-3 airplanes. This 
proposed 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 proposed AD would require 
establishing a corrosion prevention and control program to identify and 
correct corrosion and cracking. This proposed AD would also require 
completing all of the initial tasks identified in the program and 
reporting corrosion findings to Viking. The FAA is proposing this AD to 
address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by March 25,

Background

    Transport Canada, which is the aviation authority for Canada, has 
issued AD CF-2018-04, dated January 19, 2018 (referred to after this as 
``the MCAI''), to correct an unsafe condition on all serial-numbered 
Viking (formerly Bombardier Inc. and de Havilland Inc.) Model DHC-3 
airplanes. The MCAI states:

    Service experience indicates that aging aircraft are more likely 
to be adversely affected by corrosion, wear and fatigue cracking. 
Viking Air Limited (Viking), as Type Certificate holder for the DHC-
3, has developed a supplementary inspection and corrosion control 
program which identifies specific areas that must be inspected to 
ensure that corrosion, wear and fatigue-related degradation do not 
result in an unsafe condition. The program is documented in Viking 
Product Support Manual (PSM) 1-3-5 DHC-3 Otter Supplementary 
Inspection and Corrosion Control Manual (SICCM).
    Corrosion levels are defined in PSM 1-3-5 as a means for 
assessing the effectiveness of the corrosion control program and 
recording the results of the inspections mandated by this [Transport 
Canada] AD.
    Each item specified for inspection in PSM 1-3-5 has been 
substantiated to Transport Canada as having experienced significant 
degradation in service and, as having the potential to develop into 
an unsafe condition if the inspections defined in the PSM are not 
implemented.

    Corrosion and cracking, if not addressed, could lead to structural 
failure with consequent loss of control of the airplane. You may 
examine the MCAI at https://www.regulations.gov by searching for and 
locating Docket No. FAA-2020-1076.

Related Service Information

    The FAA 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 as a supplemental corrosion prevention manual, Viking Product 
Support Manual (PSM) 1-3-5 DHC-3 Otter Supplemental Inspection and 
Corrosion Control Manual, Revision IR, dated December 21, 2017 (Viking 
PSM 1-3-5, Revision IR).
    The FAA also 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.

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.

Requirements of the Proposed AD

    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. The 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.

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

    Transport Canada AD CF-2018-04 requires completing the actions as 
specified in Viking PSM 1-3-5, Revision IR. This proposed AD would not 
require Viking PSM 1-3-5, Revision IR, but would require establishing a 
corrosion prevention and control program using an FAA-approved method. 
However, the FAA considers Viking PSM 1-3-5, Revision IR, an approved 
method.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 38 airplanes of U.S. registry. The FAA also estimates that it 
would take about 145 work-hours per airplane to establish a corrosion 
prevention and control program and comply with the initial tasks of the 
program.
    Based on these figures, the FAA estimates the cost of the proposed 
AD on U.S. operators to be $468,350 or $12,325 per airplane.
    The FAA estimates it would take about 1work-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.

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

[[Page 7061]]

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: Information Collection 
Clearance Officer, Federal Aviation 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 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 this 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.
