AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: 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:

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

excessive free-play in the elevator 

control tabs for various Model DHC–3 

engine configurations. 

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: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. 

operators 

Inspection ................... 1 work-hour × $85 per hour = $85 per inspection cycle.Not applicable ............ $85 per inspection 

cycle.

$5,525 per inspection 

cycle. 

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: 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Minimum repair ............................ 1 work-hour × $85 per hour = $85 ................................................................................ $50 $135 

Moderate repair ........................... 3 work-hours × $85 per hour = $255 ............................................................................ 150 405 

Maximum repair ........................... 6 work-hours × $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 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 

1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

2. The FAA amends § 39.13 by adding 

the following new 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.

AGENCY: Federal Aviation 

Administration, DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: This document proposes 

adopting a new airworthiness directive 

(AD) for the Apical emergency float kits 

installed on certain model helicopters 

under supplemental type certificates. 

This proposal would require adding 

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. 

DATES: Comments must be received on 

or before February 7, 2011.
