Discussion
Transport Canada, which is the
aviation authority for Canada, has
issued AD Number CF–2017–11, dated
March 9, 2017 (referred to after this as
‘‘the MCAI’’), to correct an unsafe
condition for Viking Air Limited Model
DHC–3 airplanes and was based on
mandatory continuing airworthiness
information originated by an aviation
authority of another country. The MCAI
states:
Pitting corrosion has been found on the
shank of the following part number wing
strut attach bolts: C3W114–3, C3W129–3 and
C3W128–3. These bolts are manufactured
using a standard AN12 bolt. Metallurgical
evaluation concluded that pitting corrosion
was present on the affected AN12 bolts prior
to forming of the bolt head and threads. The
pitting and un-plated voids could cause a
surface condition that may have a
detrimental effect on fatigue and corrosion
resistance, leading to bolt failure and
consequent failure of the wing.
Viking has not been able to confirm the
affected batch numbers or specific
manufacture date range. New wing strut bolts
manufactured after 21 March 2016 are
inspected for pitting during manufacturing
and issued new P/Ns C3W114–5, C3W129–
5 and C3W128–5 under MOD 3/1010.
You may examine the MCAI on the
internet at https://www.regulations.gov
by searching for and locating Docket No.
FAA–2018–0189.
Related Service Information Under 1
CFR Part 51
Viking Air Limited has issued DHC–
3 Otter Service Bulletin Number V3/
0006, Revision B, dated March 9, 2017.
The service information describes
procedures for inspection and any
necessary corrective action for pitting of
the wing strut shank bolts. 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 of this NPRM.
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
E:\FR\FM\13MRP1.SGM
13MRP1
10810
Federal Register / Vol. 83, No. 49 / Tuesday, March 13, 2018 / Proposed Rules
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.
Costs of Compliance
We estimate that this proposed AD
will affect 37 products of U.S. registry.
We also estimate that it would take
about 4 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $85 per work-hour.
Based on these figures, we estimate
the cost of the proposed AD on U.S.
operators to be $12,580, or $340 per
product.
In addition, Table 1 is an estimate of
possible necessary follow-on actions as
a result of the required inspections. We
have no way of determining the number
of products that may need these actions.
We estimate that any necessary followon replacement parts would cost as
follows:
Replacing each affected bolt is on
condition and is estimated to take about
1 work-hour at $85 for a cost of $85 per
bolt.

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
applicable to small airplanes and
domestic business jet transport
airplanes 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
VerDate Sep<11>2014

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

This document contains proposed
amendments to the Procedure and
Administration Regulations (26 CFR
part 301) under section 6103(n) of the
Code. On December 4, 2015, the FAST
Act, Public Law 114–94, 129 Stat. 1312,
was enacted into law. Section 32101 of
the FAST Act adds section 7345 to the
Internal Revenue Code. Section 7345
requires the IRS to notify the
Department of State of tax debts that the
IRS certifies as seriously delinquent.
Section 7345(b) generally defines a
seriously delinquent tax debt as an
unpaid, legally enforceable Federal tax
liability of an individual that has been
assessed, is greater than $50,000 (as
indexed for inflation), and with respect
to which a notice of lien has been filed
pursuant to section 6323 and the
administrative rights under section 6320
with respect to such filing have been
exhausted or have lapsed, or a levy has
been made pursuant to section 6331.
Section 32101 of the FAST Act
generally requires the Department of
State to deny a passport (or the renewal
of a passport) in the case of an
individual if notified by the IRS that the
individual has been certified as having
a seriously delinquent tax debt and
permits the Department of State to
revoke a passport previously issued to
such person.
Under section 6103(a) of the Code,
returns and return information are
confidential unless the Code otherwise
authorizes disclosure. The FAST Act
added section 6103(k)(11), which
provides that, upon certification under
section 7345, the IRS is authorized to
disclose return information to the
Department of State with respect to a
taxpayer who has a seriously delinquent
tax debt. Specifically, upon certification
under section 7345, section
6103(k)(11)(A) authorizes the IRS to
disclose to officers and employees of the
Department of State (i) the taxpayer
identity information with respect to the
certified taxpayer and (ii) the amount of
such seriously delinquent tax debt.
Section 6103(k)(11)(A). Section
6103(k)(11)(B) limits the use of return
information disclosed under
subparagraph (A) for the purposes of,
and to the extent necessary in, carrying
out the requirements of section 32101 of
the FAST Act.

[[Page 10810]]
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.
Costs of Compliance
We estimate that this proposed AD will affect 37 products of U.S.
registry. We also estimate that it would take about 4 work-hours per
product to comply with the basic requirements of this proposed AD. The
average labor rate is $85 per work-hour.
Based on these figures, we estimate the cost of the proposed AD on
U.S. operators to be $12,580, or $340 per product.
In addition, Table 1 is an estimate of possible necessary follow-on
actions as a result of the required inspections. We have no way of
determining the number of products that may need these actions. We
estimate that any necessary follow-on replacement parts would cost as
follows:
Replacing each affected bolt is on condition and is estimated to
take about 1 work-hour at $85 for a cost of $85 per bolt.

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 applicable to small airplanes and domestic
business jet transport airplanes 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.

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-2018-0189; Product Identifier
2017-CE-022-AD.
(a) Comments Due Date
We must receive comments by April 27, 2018.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Viking Air Limited Model DHC-3 airplanes with
wing strut bolts wing strut bolts part numbers (P/N) C3W114-3,
C3W129-3 and C3W128-3 (Pre MOD 3/1010), 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 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 pitting
corrosion on the shank of the wing strut attach bolts. We are
issuing this proposed AD to detect and correct pitting and un-plated
voids, which could cause a surface condition that may have a
detrimental effect on fatigue and corrosion resistance, leading to
bolt failure and subsequent failure of the wing.
(f) Actions and Compliance
Unless already done, do the following actions:
(1) Within the next 12 months after the effective date of this
AD, inspect the wing strut attach bolts installed on the airplane
for pitting on the shank following paragraph A of the Accomplishment
Instructions of Viking DHC-3 Otter Service Bulletin (SB) Number: V3/
0006, Revision B, dated March 9, 2017.
(2) If pitting is found after the inspection required in
paragraph (f)(1) of this AD, before further flight, replace the bolt
with either a post MOD 3/1010 wing strut bolt (Part Numbers (P/Ns)
C3W114-5, C3W129-5 or C3W128-5 as applicable) or a new or
[[Page 10811]]
serviceable pre MOD 3/1010 wing strut bolt that has been inspected
following paragraph A of Viking DHC-3 Otter SB Number: V3/0006,
Revision B, dated March 9, 2017.
(3) After the effective date of this AD, pre MOD 3/1010 bolts
may continue to be used provided these bolts are inspected for
pitting immediately before installation following paragraph A of the
Accomplishment Instructions of Viking DHC-3 Otter SB Number: V3/
0006, Revision B, dated March 9, 2017, and the accomplishment of the
inspection must be documented in the airplane maintenance records.
