Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to adopt a new
airworthiness directive (AD) for the
products listed above. This proposed
AD would require 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. This proposed
AD results 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 are proposing the
inspections through the rulemaking
process. We are proposing this AD to
add new repetitive inspections of the
elevator control tabs. If these
inspections are not done, excessive freeplay 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 January 21, 2011.
ADDRESSES: You may send comments by
any of the following methods:
• Federal eRulemaking Portal: Go to
https://www.regulations.gov. Follow the

Discussion
Viking Aircraft Limited has issued
revisions to the DHC–3 Otter
maintenance manual (PSM No. 1–3–2)
to add a new inspection of the elevator
control tabs every 100 hours time-inservice. To require compliance with
these inspections for U.S. owners and
operators the inspection must be
mandated through the rulemaking
process.
These inspections, if not done, could
result in excessive free-play in the
elevator control tabs. This condition, if
not detected and corrected, could lead
to loss of tab control linkage and severe
elevator flutter. Such elevator flutter
could lead to possible loss of control.
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
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 require
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.
We are also proposing a reporting
requirement requesting information
when the total maximum free play of
the elevator servo tab and trim tab
relative to the elevator exceeds 1.0
degree (this is equal to a maximum
displacement of 0.070″ at the trailing
edge of the servo tab). Collecting this
information will help us better
understand the service history related to

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 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,
VerDate Mar<15>2010
16:44 Dec 06, 2010
Jkt 223001
(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.

placards on each side of the fuselage to
identify the location and operation of
the liferaft external inflation handle.
The proposal would also require
replacing each liferaft operation placard
to state that external liferafts are
installed. This proposal is prompted by
a report of a helicopter that crashed into
the water, and the pilot did not deploy
the floats and liferafts. Two external Thandles were available for deployment
of the liferafts but were not used by the
passengers because they were unaware
of their location. The proposed actions
are intended to prevent helicopter
occupants from further injury due to
unnecessary exposure to harsh water
conditions and to aid in deploying
liferafts when liferafts are available on
the helicopter and can be activated after
a water landing.

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 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.

airworthiness directive (AD):
Viking Air Limited (Type Certificate No. A-815 Formerly Held by
Bombardier Inc. and de Havilland, Inc.): Docket No. FAA-2010-1192;
Directorate Identifier 2010-CE-020-AD.
Comments Due Date
(a) We must receive comments by January 21, 2011.
Affected ADs
(b) None.
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:
(1) do not have the new elevator servo tab and redundant control
linkage installed according to Supplemental Type Certificate (STC)
No. SA01059SE; and
(2) 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.
