Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 64- 09-03, which applies to all de Havilland (type certificate now held by Viking Air Limited) 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. Since the FAA issued AD 64- 09-03, Transport Canada superseded its mandatory continuing airworthiness information (MCAI) to correct an unsafe condition on these products. This proposed AD would require establishing a corrosion prevention and control program to identify and correct corrosion. This proposed AD would also require completing all of the initial tasks identified in the program and reporting corrosion findings to Viking. The proposed corrosion prevention and control program would include the inspection of the aileron balance weight arms required by AD 64-09-03. The FAA is proposing this AD to address the unsafe condition on these products.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 64-
09-03, which applies to all de Havilland (type certificate now held by
Viking Air Limited) 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. Since the FAA issued AD 64-
09-03, Transport Canada superseded its mandatory continuing
airworthiness information (MCAI) to correct an unsafe condition on
these products. This proposed AD would require establishing a corrosion
prevention and control program to identify and correct corrosion. This
proposed AD would also require completing all of the initial tasks
identified in the program and reporting corrosion findings to Viking.
The proposed corrosion prevention and control program would include the
inspection of the aileron balance weight arms required by AD 64-09-03.
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,
2022.

Background
The FAA issued AD 64-09-03, Amendment 718 (29 FR 5390; April 22,
1964) (AD 64-09-03) for all de Havilland (type certificate now held by
Viking Air Limited) Model DHC-2 ``Beaver'' airplanes. AD 64-09-03
requires repetitively inspecting the aileron mass balance weight arms
for cracks and corrosion and replacing any damaged part. AD 64-09-03
resulted from cracks and corrosion found on aileron mass balance weight
arm part numbers (P/Ns) C2WA151, C2WA152, C2WA127, and C2WA128.
Actions Since AD 64-09-03 Was Issued
Since the FAA issued AD 64-09-03, the type certificate holder for
Model DHC-2 airplanes changed from de Havilland to Viking Air Limited.
Transport Canada, which is the aviation authority for Canada,
superseded its prior ADs on this unsafe condition and issued AD CF-
2019-25, dated July 5, 2019 (referred to after this as ``the MCAI''),
to correct an unsafe condition for all serial-numbered Viking Air
Limited Model DHC-2 Mk. I, DHC-2 Mk. II, and DHC-2 Mk. III airplanes.
The MCAI states:
Service experience indicates that aging aircraft are more likely
to be affected by corrosion. Viking Air Limited (Viking), as Type
Certificate holder for DHC-2, has developed a supplementary
inspection and corrosion control program which identifies specific
area that must be inspected to ensure the corrosion-related
degradation does not
[[Page 7066]]
result in an unsafe condition. The program is documented in Viking
Product Support Manual (PSM) 1-2-5 DHC-2 Beaver Supplementary
Inspection and Corrosion Control Manual (SICCM).
Corrosion levels are defined in PSM 1-2-5 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.
The initial issue of PSM 1-2-5, Revision IR, was mandated by
[Transport Canada] AD CF-2017-33. This initial issue of PSM 1-2-5
focused on the fight control systems. Viking has revised PS 1-2-5 to
Revision 1. This revision includes additional inspection tasks for
components of airframe systems other than flight controls. This
[Transport Canada] AD is issued to require accomplishment of those
additional inspection tasks and supersedes [Transport Canada] AD CF-
2017-33.
This [Transport Canada] AD continues to require accomplishment
of the tasks that were included in the initial issue of PSM 1-2-5.
Note: The tasks being carried over from Revision IR to Revision 1
are required to be performed in accordance with the current revision
of the PSM 1-2-5, reference [Canadian Aviation Regulation] CAR
571.02 paragraph (1) (a).
Transport Canada (TC) has concluded that Tasks C57-51-01 and
C57-51-02 make the repetitive inspections required by [Transport
Canada] AD CF-61-12 [which corresponds to FAA AD 64-09-03]
unnecessary. CF-61-12 is therefore cancelled.
Viking determined that changes to the compliance times for two
of the tasks in PSM 1-2-5 were required. For task C57-51-01 the
repeat interval was every 1 year in Revision IR and is changed to
every 2 years in Revision 1. For task C57-51-02 the repeat interval
was every 4 years in Revision IR and is changed to every 4 years or
500 hours air time, whichever occurs first, in Revision 1.
Corrosion-related degradation, if not addressed, could lead to
structural failure with consequent loss of control of the airplane. You
may examine the MCAI at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for
and locating Docket No. FAA-2020-7071.
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.
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.
