39–16510; AD 2010–23–21]
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on July 23, 2010, (75 FR
43092). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:

Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
AGENCY:
We are adopting a new
airworthiness directive (AD) for the
products listed above. This 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:
SUMMARY:
erowe on DSK5CLS3C1PROD with RULES
Viking Air Limited has completed a system
safety review of the aircraft fuel system
against fuel tank safety standards introduced
in Chapter 525 of the Airworthiness Manual
through Notice of Proposed Amendment
(NPA) 2002–043. The identified noncompliances were then assessed using
Transport Canada Policy Letter No. 525–001,
to determine if mandatory corrective action
is required.
The assessment showed that supplemental
maintenance tasks would be required to
prevent potential ignition sources within the
fuel system, which could result in a fuel tank
explosion. * * *
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective
December 22, 2010.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in this AD
as of December 22, 2010.

Viking Air Limited has completed a system
safety review of the aircraft fuel system
against fuel tank safety standards introduced
in Chapter 525 of the Airworthiness Manual
through Notice of Proposed Amendment
(NPA) 2002–043. The identified noncompliances were then assessed using
Transport Canada Policy Letter No. 525–001,
to determine if mandatory corrective action
is required.
The assessment showed that supplemental
maintenance tasks would be required to
prevent potential ignition sources within the
fuel system, which could result in a fuel tank
explosion. Viking Air Limited has revised
Chapter 5 of the DHC–7 Maintenance
Manual, PSM 1–7–2, to introduce the
required maintenance tasks.
The corrective action is revising the
Airworthiness Limitations Section of
the Instructions for Continued
Airworthiness to incorporate new
limitations for fuel tank systems. You
may obtain further information by
examining the MCAI in the AD docket.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM or
on the determination of the cost to the
public.
Clarification of Table Reference
Table 1—Temporary Revisions of the
NPRM has a typographical error. ‘‘FLS–
06’’ is corrected in Table 1 of this AD
to ‘‘FSL–06.’’
Clarification of Viking DHC–7 Dash 7
Maintenance Manual Section Number
Paragraph (g) of the NPRM has a
typographical error. ‘‘Section 5–10–30’’
is corrected in paragraph (g) of this AD
to ‘‘Section 5–10–13.’’
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
with the correction described
previously. We determined that this
correction will not increase the
economic burden on any operator or
increase the scope of the AD.

Differences Between This AD and the
MCAI or Service Information
We have reviewed the MCAI and
related service information and, in
general, agree with their substance. But
we might have found it necessary to use
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable. In making
these changes, we do not intend to differ
substantively from the information
provided in the MCAI and related
service information.
We might also have required different
actions in this AD from those in the
MCAI in order to follow our FAA
policies. Any such differences are
highlighted in a Note within the AD.
Costs of Compliance
We estimate that this AD will affect
11 products of U.S. registry. We also
estimate that it will take about 1 workhour per product to comply with the
basic requirements of this AD. The
average labor rate is $85 per work-hour.
Based on these figures, we estimate the
cost of this AD to the U.S. operators to
be $935, or $85 per product.
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.
Regulatory Findings
We determined that this AD will not
have federalism implications under
Executive Order 13132. This AD will
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 AD:
1. Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
E:\FR\FM\17NOR1.SGM
17NOR1
Federal Register / Vol. 75, No. 221 / Wednesday, November 17, 2010 / Rules and Regulations
2. Is not a ‘‘significant rule’’ under the
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979); and
3. 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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.

another country to identify and correct an unsafe condition on an
aviation product. The MCAI describes the unsafe condition as:
Viking Air Limited has completed a system safety review of the
aircraft fuel system against fuel tank safety standards introduced

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on July 23, 2010, (75
FR 43092). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
Viking Air Limited has completed a system safety review of the
aircraft fuel system against fuel tank safety standards introduced
in Chapter 525 of the Airworthiness Manual through Notice of
Proposed Amendment (NPA) 2002-043. The identified non-compliances
were then assessed using Transport Canada Policy Letter No. 525-001,
to determine if mandatory corrective action is required.
The assessment showed that supplemental maintenance tasks would
be required to prevent potential ignition sources within the fuel
system, which could result in a fuel tank explosion. Viking Air
Limited has revised Chapter 5 of the DHC-7 Maintenance Manual, PSM
1-7-2, to introduce the required maintenance tasks.
The corrective action is revising the Airworthiness Limitations Section
of the Instructions for Continued Airworthiness to incorporate new
limitations for fuel tank systems. You may obtain further information
by examining the MCAI in the AD docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Clarification of Table Reference
Table 1--Temporary Revisions of the NPRM has a typographical error.
``FLS-06'' is corrected in Table 1 of this AD to ``FSL-06.''
Clarification of Viking DHC-7 Dash 7 Maintenance Manual Section Number
Paragraph (g) of the NPRM has a typographical error. ``Section 5-
10-30'' is corrected in paragraph (g) of this AD to ``Section 5-10-
13.''
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD with the correction
described previously. We determined that this correction will not
increase the economic burden on any operator or increase the scope of
the AD.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a Note within the AD.
Costs of Compliance
We estimate that this AD will affect 11 products of U.S. registry.
We also estimate that it will take about 1 work-hour per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Based on these figures, we estimate the cost of
this AD to the U.S. operators to be $935, or $85 per product.
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.
Regulatory Findings
We determined that this AD will not have federalism implications
under Executive Order 13132. This AD will 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 AD:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
[[Page 70107]]
2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); and
3. Will not have a significant economic impact, positive or

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 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:
2010-23-21 Viking Air Limited (Type Certificate Previously Held by
Bombardier, Inc.): Amendment 39-16510. Docket No. FAA-2010-0699;
Directorate Identifier 2009-NM-236-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective December
22, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Viking Air Limited (Type Certificate
previously held by Bombardier, Inc.) Model DHC-7-1, DHC-7-100, DHC-
7-101, DHC-7-102, and DHC-7-103 airplanes; certificated in any
category.
Subject
(d) Air Transport Association (ATA) of America Code 28: Fuel.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Viking Air Limited has completed a system safety review of the
aircraft fuel system against fuel tank safety standards introduced
in Chapter 525 of the Airworthiness Manual through Notice of
Proposed Amendment (NPA) 2002-043. The identified non-compliances
were then assessed using Transport Canada Policy Letter No. 525-001,
to determine if mandatory corrective action is required.
The assessment showed that supplemental maintenance tasks would
be required to prevent potential ignition sources within the fuel
system, which could result in a fuel tank explosion. * * *
The corrective action is revising the Airworthiness Limitations
Section of the Instructions for Continued Airworthiness to
incorporate new limitations for fuel tank systems.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Actions
(g) Within 60 days after the effective date of this AD,
incorporate all the fuel system limitation (FSL) tasks as specified
in the temporary revisions (TR) listed in Chapter 5 of the Viking
Dash 7 Series 1/100 Aircraft Maintenance Manual (AMM), PSM 1-7-2;

identified in paragraph (g) of this AD in the AMM. When these TRs
have been included in general revisions of the AMM, the general
revisions may be inserted in the AMM, provided the relevant
information in the general revision is identical to that in the TRs
identified in paragraph (g) of this AD.
