recognition of the complexities of the
rulemaking and the variety of
considerations involved in its impact
and implementation, the Agencies
requested that commenters respond to
numerous questions. The Credit Risk
NPR stated that the public comment
period would close on June 10, 2011.2
The Agencies have received requests
from the public for an extension of the
comment period to allow for sufficient
time for data gathering and impact
analyses related to the provisions of the
proposed rule.3 The Agencies believe
that it is important for interested
persons to have additional time to fully
review the provisions of the proposed
rule and the questions posed by the
Agencies, and to conduct appropriate
data collection and analysis on the
potential impact of the Credit Risk NPR
prior to submitting comment. Therefore,
the Agencies are extending the comment
period for the Credit Risk NPR from
June 10, 2011 to August 1, 2011.

Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to supersede an
existing airworthiness directive (AD)
that applies to the products listed above.
The existing AD currently requires
repetitively inspecting the elevator
control tabs for discrepancies and, if any
discrepancies are found, taking
necessary corrective actions to bring all
discrepancies within acceptable
tolerances. The existing AD also
requires reporting certain inspection
results to the FAA. Since we issued that
AD, we determined that we
inadvertently omitted certain airplanes
from the Applicability section. This
proposed AD would retain the actions
currently required in AD 2011–05–02
and remove the Supplemental Type
Certificate (STC) SA01059SE condition
in the Applicability section. We are
proposing 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.
DATES: We must receive comments on
this proposed AD by July 25, 2011.
ADDRESSES: You may send comments by

Discussion
On February 15, 2011, we issued AD
2011–05–02, Amendment 39–16611 (76
FR 10220, February 24, 2011), for
certain Viking Air Limited (Type
Certificate No. A–815 formerly held by
Bombardier Inc. and de Havilland, Inc.)
Model DHC–3 airplanes. That AD
requires repetitively inspecting the

elevator control tabs for discrepancies
and, if any discrepancies are found,
taking necessary corrective actions to
bring all discrepancies within
acceptable tolerances. That AD also
requires reporting certain inspection
results to the FAA. That AD resulted
from an evaluation of revisions to the
manufacturer’s maintenance manual
that adds new repetitive inspections of
the elevator control tabs. To require
compliance with these inspections for
U.S. owners and operators we mandated
the inspections through the rulemaking
process. We issued that 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.
Actions Since Existing AD Was Issued
Since we issued AD 2011–05–02, we
determined that we inadvertently
omitted certain airplanes from the
Applicability section. The current
Applicability section includes Model
DHC–3 airplanes, all serial numbers,
that do not have the new elevator servo
tab and redundant control linkage
installed according to Supplemental
Type Certificate (STC) No. SA01059SE
and that are certificated in any category.
The actions currently required in AD
2011–05–02 were intended for all Model
DHC–3 airplanes regardless if the
installation of the redundant linkage
was done according to Supplemental
Type Certificate (STC) SA01059SE.
develop in other products of the same
type design.
Proposed AD Requirements
This proposed AD would retain all of
the requirements of AD 2011–05–02.
This proposed AD would add airplanes
to the applicability statement of the
existing AD by removing the STC
SA01059SE condition.
Interim Action
We are continuing to evaluate the
cause of the unsafe condition identified
in this proposed 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.
FAA’s Determination
Costs of Compliance
We are proposing this AD because we

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
VerDate Mar<15>2010
14:30 Jun 09, 2011

Parts cost
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
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:

(a) The FAA must receive comments on
this AD action by July 25, 2011.
(b) This AD supersedes AD 2011–05–02,
Amendment 39–16611.
Authority: 49 U.S.C. 106(g), 40113, 44701.
[Amended]
2. The FAA amends § 39.13 by
removing airworthiness directive (AD)
AD 2011–05–02, Amendment 39–16611
(76 FR 10220, February 24, 2011), and
adding the following new AD:
Viking Air Limited (Type Certificate No. A–
815 Formerly Held by Bombardier Inc.
Unsafe Condition
(e) 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.

Discussion
On February 15, 2011, we issued AD 2011-05-02, Amendment 39-16611
(76 FR 10220, February 24, 2011), for certain Viking Air Limited (Type
Certificate No. A-815 formerly held by Bombardier Inc. and de
Havilland, Inc.) Model DHC-3 airplanes. That AD requires repetitively
inspecting the
[[Page 34012]]
elevator control tabs for discrepancies and, if any discrepancies are
found, taking necessary corrective actions to bring all discrepancies
within acceptable tolerances. That AD also requires reporting certain
inspection results to the FAA. That AD resulted from an evaluation of
revisions to the manufacturer's maintenance manual that adds new
repetitive inspections of the elevator control tabs. To require
compliance with these inspections for U.S. owners and operators we
mandated the inspections through the rulemaking process. We issued that
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.
Actions Since Existing AD Was Issued
Since we issued AD 2011-05-02, we determined that we inadvertently
omitted certain airplanes from the Applicability section. The current
Applicability section includes Model DHC-3 airplanes, all serial
numbers, that do not have the new elevator servo tab and redundant
control linkage installed according to Supplemental Type Certificate
(STC) No. SA01059SE and that are certificated in any category.
The actions currently required in AD 2011-05-02 were intended for
all Model DHC-3 airplanes regardless if the installation of the
redundant linkage was done according to Supplemental Type Certificate
(STC) SA01059SE.
FAA's Determination
We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
Proposed AD Requirements
This proposed AD would retain all of the requirements of AD 2011-
05-02. This proposed AD would add airplanes to the applicability
statement of the existing AD by removing the STC SA01059SE condition.
Interim Action
We are continuing to evaluate the cause of the unsafe condition
identified in this proposed 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 proposed AD affects 65 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:

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

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 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) 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
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]
2. The FAA amends Sec. 39.13 by removing airworthiness directive
(AD) AD 2011-05-02, Amendment 39-16611 (76 FR 10220, February 24,
2011), and adding the following new AD:
Viking Air Limited (Type Certificate No. A-815 Formerly Held by
Bombardier Inc. and de Havilland, Inc.): Docket No. FAA-2011-0597;
Directorate Identifier 2011-CE-019-AD.
Comments Due Date
(a) The FAA must receive comments on this AD action by July 25,
2011.
Affected ADs
(b) This AD supersedes AD 2011-05-02, Amendment 39-16611.
Applicability
(c) 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.
Subject
(d) Joint Aircraft System Component (JASC)/Air Transport
Association (ATA) of America Code 27, Flight Controls.
Unsafe Condition
(e) 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.
Compliance
(f) Comply with this AD within the compliance times specified,
unless already done.
