Federal Register Abstract
We are superseding an existing airworthiness directive (AD) for all Viking Air Limited (type certificate No. A-815 formerly held by Bombardier Inc. and de Havilland, Inc.) Model DHC-3 airplanes. That AD currently requires repetitively inspecting the elevator control tabs for discrepancies, taking necessary corrective actions to bring all discrepancies within acceptable tolerances, and reporting certain inspection results to the FAA. This new AD retains the actions currently required in AD 2011-05-02 and removes the Supplemental Type Certificate (STC) SA01059SE condition in the Applicability section. This AD was prompted by our determination that we inadvertently omitted certain airplanes from the Applicability section. We are issuing this AD to correct the unsafe condition on these products.

(c) Applicability
This AD applies to Viking Air Limited (type certificate No. A-

DHC-3 airplanes, all serial numbers, that are certificated in any

ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding an existing airworthiness directive (AD)
for all Viking Air Limited (type certificate No. A-815 formerly held by
Bombardier Inc. and de Havilland, Inc.) Model DHC-3 airplanes. That AD
currently requires repetitively inspecting the elevator control tabs
for discrepancies, taking necessary corrective actions to bring all
discrepancies within acceptable tolerances, and reporting certain
inspection results to the FAA. This new AD retains the actions
currently required in AD 2011-05-02 and removes the Supplemental Type
Certificate (STC) SA01059SE condition in the Applicability section.
This AD was prompted by our determination that we inadvertently omitted
certain airplanes from the Applicability section. We are issuing this
AD to correct the unsafe condition on these products.
DATES: This AD is effective October 3, 2011.
The Director of the Federal Register approved the incorporation by
reference of certain other publications listed in this AD as of March
31, 2011 (76 FR 10220, February 24, 2011).

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2011-05-02, Amendment 39-16611 (76 FR 10220,
February 24, 2011). That AD applies to the specified products. The NPRM
published in the Federal Register on June 10, 2011 (76 FR 34011). That
NPRM proposed to retain all of the requirements of AD 2011-05-02 and
add airplanes to the Applicability section removing the Supplemental
Type Certificate (STC) SA01059SE condition.
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.
Conclusion
We reviewed the relevant data and determined that air safety and
the public interest require adopting the AD as proposed except for
minor editorial changes. We have determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM.
Interim Action
We are continuing to evaluate the cause of the unsafe condition
identified in this AD to enable us to obtain better insight into the
nature, cause, and extent of excessive free-play in the elevator
control tabs. Based on this evaluation, we may consider further
rulemaking.
Costs of Compliance
We estimate that this AD affects 65 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

----------------------------------------------------------------------------------------------------------------
We estimate the following costs to do any necessary follow-on
actions that will be required based on the results of the inspection.
We have no way of determining the number of airplanes that may need
this repair/replacement:

Maximum repair................................ 6 work-hours x $85 per hour = $510.... 450 960
----------------------------------------------------------------------------------------------------------------
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 have 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 that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under 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.

Adoption of the Amendment
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]
The FAA amends Sec. 39.13 by removing airworthiness directive (AD)
2011-05-02, Amendment 39-16611 (76 FR 10220, February 24, 2011), and
adding the following new AD:
2011-18-11 Viking Air Limited (Type Certificate No. A-815 Formerly
Held by Bombardier Inc. and de Havilland, Inc.): Amendment 39-16793;
Docket No. FAA-2011-0597; Directorate Identifier 2011-CE-019-AD.
(a) Effective Date
This airworthiness directive (AD) is effective October 3, 2011.
(b) Affected ADs
This AD supersedes AD 2011-05-02, Amendment 39-16611 (76 FR
10220, February 24, 2011).
(c) Applicability
This AD applies to Viking Air Limited (type certificate No. A-
815 formerly held by Bombardier Inc. and de Havilland, Inc.) Model
DHC-3 airplanes, all serial numbers, that are certificated in any
category.
(d) Subject
Joint Aircraft System Component (JASC)/Air Transport Association
(ATA) of America Code 27, Flight Controls.
(e) Unsafe Condition
This AD results from an evaluation of revisions to the
manufacturer's maintenance manual that adds new repetitive
inspections to the elevator control tabs. To require compliance with
these inspections for U.S. owners and operators we are mandating
these inspections through the rulemaking process. We are issuing
this AD to add new repetitive inspections of the elevator control
tabs. If these inspections are not done, excessive free-play in the
elevator control tabs could develop. This condition could lead to
loss of tab control linkage and severe elevator flutter. Such
elevator flutter could lead to possible loss of control.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
