This section of the FEDERAL REGISTER
contains notices to the public of the proposed
issuance of rules and regulations. The
purpose of these notices is to give interested
persons an opportunity to participate in the
rule making prior to the adoption of the final
rules.

Airworthiness Directives; Viking Air
Limited Airplanes
Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Supplemental notice of
proposed rulemaking (SNPRM);
reopening of the comment period.
AGENCY:
We are revising an earlier
proposal for all Viking Air Limited
Models DHC–2 Mk. I, DHC–2 Mk. II,
and DHC–2 Mk. III airplanes. This
proposed airworthiness directive (AD)
results from mandatory continuing
airworthiness information (MCAI)
originated by an aviation authority of
another country to identify and address
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as cracking found in the wing
rear spar web at the wing station where
the flap outboard hinge is attached. This
action revises the proposal by issuing an
SNPRM that changes the compliance
times to more closely match the
compliance times in the MCAI. We are
proposing this AD to address the unsafe
condition on these products. Since these
actions may impose an additional
burden over those in the notice of
proposed rulemaking (NPRM), we are
reopening the comment period to allow
the public the opportunity to comment
on these changes.
DATES: We must receive comments on
this proposed AD by June 21, 2018.
ADDRESSES: You may send comments by
any of the following methods:
• Federal eRulemaking Portal: Go to
https://www.regulations.gov. Follow the
instructions for submitting comments.

Discussion
We proposed to amend 14 CFR part
39 with an NPRM for all Viking Air
Limited Models DHC–2 Mk. I, DHC–2
Mk. II, and DHC–2 Mk. III airplanes,
which was published in the Federal
Register on September 8, 2017 (82 FR
42489). The NPRM proposed to require
actions intended to address the unsafe
condition for the products listed above
and was based on MCAI originated by
another country.
Since the NPRM was issued, we
received a comment to change the
compliance time for the inspections in
the NPRM to be in line with the
compliance times stated in Transport
Canada, which is the aviation authority
for Canada, AD Number CF–2017–17,
dated May 18, 2017 (referred to after
this as ‘‘the MCAI’’).
Comments
We have considered the following
comment received on the NPRM.
Request To Change the Compliance
Times for the Inspections
Adam Geber stated that the
compliance times in the NPRM for the
inspections specified in paragraphs
(f)(1) and (f)(2) should be changed to
match the compliance times stated in
the MCAI AD and the related service
information.
Adam Geber requested including the
6-month compliance time from the
MCAI AD into the proposed AD.
We agree with the commenter. We
have changed paragraphs (f)(1) and (f)(2)
in this SNPRM from ‘‘within the next
400 hours TIS after the effective date of
this AD’’ to ‘‘within the next 400 hours
TIS after the effective date of this AD or
within the next 6 months after the
effective date of this AD, whichever
occurs first.’’

Related Service Information Under 1
CFR Part 51
Viking Air Limited has issued DHC–
2 Beaver Service Bulletin Number: V2/
0009, Revision A, dated February 10,
2017. The service information describes
procedures for inspecting the left-hand
and right-hand wing rear spars, the flap/
aileron hinge brackets, and the exterior
store support bracket for cracks,
damage, and discrepancies and specifies
repairing or replacing any cracked,
damaged, or discrepant 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.
in the United States. Pursuant to our
bilateral agreement with this State of
Design Authority, they have notified us
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all
information and determined the unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
The change described above expands
the scope of the NPRM. As a result, we
have determined that it is necessary to
reopen the comment period to provide
additional opportunity for the public to
comment on the proposed AD.

Costs of Compliance
We estimate that this SNPRM will
affect 140 products of U.S. registry. We
also estimate that it would take about 11
work-hours per product to comply with
the basic inspection requirements of this
SNPRM. The average labor rate is $85
per work-hour.
Based on these figures, we estimate
the basic cost of this proposed AD on
U.S. operators to be $130,900, or $935
per product.
In addition, the following is an
estimate of possible necessary follow-on
replacement actions. We have no way of

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 current valid
OMB control number. The control
number for the collection of information
required by this AD is 2120–0056. The
paperwork cost associated with this AD
has been detailed in the Costs of
Compliance section of this document
and includes time for reviewing
instructions, as well as completing and
VerDate Sep<11>2014

reviewing the collection of information.
Therefore, all reporting associated with
this AD is mandatory. Comments
concerning the accuracy of this burden
and suggestions for reducing the burden
should be directed to the FAA at 800
Independence Ave. SW, Washington,
DC 20591. ATTN: Information
Collection Clearance Officer, AES–200.
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.
We are issuing this rulemaking under
the authority described in ‘‘Subtitle VII,
Part A, Subpart III, section 44701:
PO 00000
Frm 00002
Fmt 4702
Sfmt 4702
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.
This AD is issued in accordance with
authority delegated by the Executive
Director, Aircraft Certification Service,
as authorized by FAA Order 8000.51C.
In accordance with that order, issuance
of ADs is normally a function of the
Compliance and Airworthiness
Division, but during this transition
period, the Executive Director has
delegated the authority to issue ADs
E:\FR\FM\07MYP1.SGM
07MYP1
Federal Register / Vol. 83, No. 88 / Monday, May 7, 2018 / Proposed Rules
applicable to small airplanes, gliders,
balloons, airships, domestic business jet
transport airplanes, and associated
appliances to the Director of the Policy
and Innovation Division.
Regulatory Findings
We 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) Is not a ‘‘significant rule’’ under
the DOT Regulatory Policies and
Procedures (44 FR 11034, February 26,
1979),
(3) Will not affect intrastate aviation
in Alaska, and
(4) 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation
safety, Incorporation by Reference,

The Proposed Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA proposes to amend 14 CFR part
39 as follows:

Jkt 244001
(d) Subject
Air Transport Association of America
(ATA) Code 57: Wings.
(e) Reason
This AD was prompted by mandatory
continuing airworthiness information (MCAI)
originated by an aviation authority of another
country to identify and address an unsafe
condition on an aviation product. The MCAI
describes the unsafe condition as cracking
found in the wing rear spar web at the wing
station (WS) where the flap outboard hinge
is attached. We are issuing this AD to detect
and correct cracks in the wing rear spars and
the flap/aileron hinge arm support brackets,
which could cause these parts to fail. Failure
of the wing rear spars and the flap/aileron
hinge arm support brackets could result in
loss of control.
(f) Actions and Compliance
Unless already done, do the actions in
paragraphs (f)(1) through (5) of this AD:
(1) Within the next 400 hours time-inservice (TIS) after the effective date of this
AD or within the next 6 months after the
effective date of this AD, whichever occurs
first, visually inspect the left-hand and righthand wing rear spar and flap/aileron hinge
arm support brackets following the
Accomplishment Instructions of Viking
DHC–2 Beaver Service Bulletin Number: V2/
0009, Revision A, dated February 10, 2017
(SB V2/0009, Revision A).
(2) For airplanes with agricultural
configuration installed (SOO Mod 2/984),
within the next 400 hours TIS after the
effective date of this AD or within the next
6 months after the effective date of this AD,
whichever occurs first, inspect the exterior
store support arm bracket at wing station
(WS) 101.24 following the Accomplishment
Instructions of SB V2/0009, Revision A.
(3) If any discrepancies are found during
the inspections required in paragraphs (f)(1)
and (2) of this AD, before further flight, repair
or replace using a method approved by the
Manager, New York ACO Branch, FAA; or
Transport Canada; or Viking Air Limited’s
Transport Canada Design Organization
Approval (DOA). If approved by the DOA,
the approval must include the DOAauthorized signature.
(4) Within 30 days after completing the
inspections required in paragraphs (f)(1) and
(2) of this AD, using the Operator Reply Form
on page 7 of SB V2/0009, Revision A, report
the inspection results to Viking Air Limited
at the address specified in paragraph (h) of
this AD.
(5) As of the effective date of this AD, do
not install a wing on any airplane affected by
this AD unless it has been inspected as
specified in paragraph (f)(1) of this AD and
paragraph (f)(2) of this AD, as applicable, and
is found free of any discrepancies.
(g) Other FAA AD Provisions
The following provisions also apply to this
AD:
(1) Alternative Methods of Compliance
(AMOCs): The Manager, New York ACO
Branch, FAA, has the authority to approve
AMOCs for this AD, if requested using the
procedures found in 14 CFR 39.19. Send

ACTION: Supplemental notice of proposed rulemaking (SNPRM); reopening
of the comment period.
-----------------------------------------------------------------------
SUMMARY: We are revising an earlier proposal for all Viking Air Limited
Models DHC-2 Mk. I, DHC-2 Mk. II, and DHC-2 Mk. III airplanes. This
proposed airworthiness directive (AD) results from mandatory continuing
airworthiness information (MCAI) originated by an aviation authority of
another country to identify and address an unsafe condition on an
aviation product. The MCAI describes the unsafe condition as cracking
found in the wing rear spar web at the wing station where the flap
outboard hinge is attached. This action revises the proposal by issuing
an SNPRM that changes the compliance times to more closely match the
compliance times in the MCAI. We are proposing this AD to address the
unsafe condition on these products. Since these actions may impose an
additional burden over those in the notice of proposed rulemaking
(NPRM), we are reopening the comment period to allow the public the
opportunity to comment on these changes.
DATES: We must receive comments on this proposed AD by June 21, 2018.
ADDRESSES: You may send comments by any of the following methods:

(referred to after this as ``the MCAI'').
Comments
We have considered the following comment received on the NPRM.
Request To Change the Compliance Times for the Inspections
Adam Geber stated that the compliance times in the NPRM for the
inspections specified in paragraphs (f)(1) and (f)(2) should be changed
to match the compliance times stated in the MCAI AD and the related
service information.
Adam Geber requested including the 6-month compliance time from the
MCAI AD into the proposed AD.
We agree with the commenter. We have changed paragraphs (f)(1) and
(f)(2) in this SNPRM from ``within the next 400 hours TIS after the
effective date of this AD'' to ``within the next 400 hours TIS after
the effective date of this AD or within the next 6 months after the
effective date of this AD, whichever occurs first.''

Related Service Information Under 1 CFR Part 51
Viking Air Limited has issued DHC-2 Beaver Service Bulletin Number:
V2/0009, Revision A, dated February 10, 2017. The service information
describes procedures for inspecting the left-hand and right-hand wing
rear spars, the flap/aileron hinge brackets, and the exterior store
support bracket for cracks, damage, and discrepancies and specifies
repairing or replacing any cracked, damaged, or discrepant 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.
FAA's Determination and Requirements of the Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. We are proposing this AD because
we evaluated all information and determined the unsafe condition exists
and is likely to exist or develop on other products of the same type
design.
The change described above expands the scope of the NPRM. As a
result, we have determined that it is necessary to reopen the comment
period to provide additional opportunity for the public to comment on
the proposed AD.
Interim Action
We consider this SNPRM interim action. The inspection report
required by this SNPRM allows us to obtain better information into the
nature, cause, and extent of the damage to the wing rear spars and
flap/aileron hinge arm support brackets and to develop final action to
address the unsafe condition. Once final action has been identified, we
may consider further rulemaking.
Costs of Compliance
We estimate that this SNPRM will affect 140 products of U.S.
registry. We also estimate that it would take about 11 work-hours per
product to comply with the basic inspection requirements of this SNPRM.
The average labor rate is $85 per work-hour.
Based on these figures, we estimate the basic cost of this proposed
AD on U.S. operators to be $130,900, or $935 per product.
In addition, the following is an estimate of possible necessary
follow-on replacement actions. We have no way of determining the number
of products that may need these actions.

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 current valid OMB control number. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and reviewing the
collection of information. Therefore, all reporting associated with
this AD is mandatory. Comments concerning the accuracy of this burden
and suggestions for reducing the burden should be directed to the FAA
at 800 Independence Ave. SW, Washington, DC 20591. ATTN: Information
Collection Clearance Officer, AES-200.
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.
We are 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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs
[[Page 19985]]
applicable to small airplanes, gliders, balloons, airships, domestic
business jet transport airplanes, and associated appliances to the
Director of the Policy and Innovation Division.
Regulatory Findings
We 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) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
List of Subjects in 14 CFR Part 39

Reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
Viking Air Limited: Docket No. FAA-2017-0867; Product Identifier
2017-CE-021-AD.
(a) Comments Due Date
We must receive comments by June 21, 2018.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Viking Air Limited Models DHC-2 Mk. I, DHC-2
Mk. II, and DHC-2 Mk. III airplanes, all serial numbers,
certificated in any category.
(d) Subject
Air Transport Association of America (ATA) Code 57: Wings.
(e) Reason
This AD was prompted by mandatory continuing airworthiness
information (MCAI) originated by an aviation authority of another
country to identify and address an unsafe condition on an aviation
product. The MCAI describes the unsafe condition as cracking found
in the wing rear spar web at the wing station (WS) where the flap
outboard hinge is attached. We are issuing this AD to detect and
correct cracks in the wing rear spars and the flap/aileron hinge arm
support brackets, which could cause these parts to fail. Failure of
the wing rear spars and the flap/aileron hinge arm support brackets
could result in loss of control.
(f) Actions and Compliance
Unless already done, do the actions in paragraphs (f)(1) through
(5) of this AD:
(1) Within the next 400 hours time-in-service (TIS) after the
effective date of this AD or within the next 6 months after the
effective date of this AD, whichever occurs first, visually inspect
the left-hand and right-hand wing rear spar and flap/aileron hinge
arm support brackets following the Accomplishment Instructions of
Viking DHC-2 Beaver Service Bulletin Number: V2/0009, Revision A,
dated February 10, 2017 (SB V2/0009, Revision A).
(2) For airplanes with agricultural configuration installed (SOO
Mod 2/984), within the next 400 hours TIS after the effective date
of this AD or within the next 6 months after the effective date of
this AD, whichever occurs first, inspect the exterior store support
arm bracket at wing station (WS) 101.24 following the Accomplishment
Instructions of SB V2/0009, Revision A.
(3) If any discrepancies are found during the inspections
required in paragraphs (f)(1) and (2) of this AD, before further
flight, repair or replace using a method approved by the Manager,
New York ACO Branch, FAA; or Transport Canada; or Viking Air
Limited's Transport Canada Design Organization Approval (DOA). If
approved by the DOA, the approval must include the DOA-authorized
signature.
(4) Within 30 days after completing the inspections required in
paragraphs (f)(1) and (2) of this AD, using the Operator Reply Form
on page 7 of SB V2/0009, Revision A, report the inspection results
to Viking Air Limited at the address specified in paragraph (h) of
this AD.
(5) As of the effective date of this AD, do not install a wing
on any airplane affected by this AD unless it has been inspected as
specified in paragraph (f)(1) of this AD and paragraph (f)(2) of
this AD, as applicable, and is found free of any discrepancies.
(g) Other FAA AD Provisions
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, New
York ACO Branch, FAA, has the authority to approve AMOCs for this
AD, if requested using the procedures found in 14 CFR 39.19. Send
information to ATTN: Aziz Ahmed, Aerospace Engineer, FAA, New York
ACO Branch, 1600 Stewart Avenue, Suite 410, Westbury, New York
11590; telephone: (516) 228-7329; fax: (516) 794-5531; email:
[email protected]. Before using any approved AMOC on any airplane
to which the AMOC applies, notify your appropriate principal
inspector (PI) in the FAA Flight Standards District Office (FSDO),
or lacking a PI, your local FSDO.
(2) Contacting the Manufacturer: For any requirement in this AD
to obtain corrective actions from a manufacturer, the action must be
accomplished using a method approved by the Manager, New York ACO
Branch, FAA; or Transport Canada; or Viking Air Limited's Transport
Canada Design Organization Approval (DOA). If approved by the DOA,
the approval must include the DOA-authorized signature.
(3) Reporting Requirements: For any reporting requirement in
this AD, 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 current 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 be approximately 5 minutes per response, including the
time for reviewing instructions, completing and reviewing the
collection of information. All responses to this collection of
information are mandatory. Comments concerning the accuracy of this
burden and suggestions for reducing the burden should be directed to
the FAA at: 800 Independence Ave. SW, Washington, DC 20591, Attn:
