AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for Bell 

Helicopter Textron, Inc. (Bell) Model 

206A, 206B, 206L, 206L–1, 206L–3,

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to participate in this 

rulemaking by submitting written 

comments, data, or views. We also 

invite comments relating to the 

economic, environmental, energy, or 

federalism impacts that might result 

from adopting the proposals in this 

document. The most helpful comments 

reference a specific portion of the 

proposal, explain the reason for any 

recommended change, and include 

supporting data. To ensure the docket 

does not contain duplicate comments, 

commenters should send only one copy 

of written comments, or if comments are 

filed electronically, commenters should 

submit only one time. 

We will file in the docket all 

comments that we receive, as well as a 

report summarizing each substantive 

public contact with FAA personnel 

concerning this proposed rulemaking. 

Before acting on this proposal, we will 

consider all comments we receive on or 

before the closing date for comments. 

We will consider comments filed after 

the comment period has closed if it is 

possible to do so without incurring 

expense or delay. We may change this 

proposal in light of the comments we 

receive. 

Discussion 

We propose to adopt a new AD for 

Bell Model 206A, 206B, 206L, 206L–1, 

206L–3, 206L–4, and 407 helicopters 

with an Apical emergency float kit 

installed under STC number 

SR01535LA. This proposed AD is 

prompted by an incident in which the 

floats did not deploy evenly and the 

right-hand (RH) mid-float ruptured on a 

helicopter modified with an Apical 

emergency float kit. An investigation 

determined that the uneven deployment 

resulted from incorrect installation of 

the float inflation hoses on the port 

fitting at the base of the forward 

crosstube saddle. Subsequent inspection 

of one operator’s fleet revealed more 

instances of incorrect inflation hose 

installation. This proposed AD would 

require inspecting the hoses at the port 

fittings for correct installation and 

condition, labeling the port fittings, and 

replacing the float inflation hoses. We 

are proposing this AD to prevent failure 

of the emergency floats to inflate fully 

in an emergency. 

FAA’s Determination 

We are proposing this AD because we 

evaluated all known relevant 

information and determined that an 

unsafe condition exists and is likely to 

exist or develop on other products of the 

same type design. 

Related Service Information 

We have reviewed Apical Alert 

Service Bulletin No. SB2010–03, 

Revision C, dated December 21, 2011 

(ASB). The ASB provides instructions 

for inspecting the float inflation hoses, 

installing an aft float label onto the port 

fittings, installing a port fitting adapter 

on the port fittings, and replacing the 

hoses leading to the aft floats of each 

affected helicopter. 

Proposed AD Requirements 

This proposed AD would require: 

• Within 45 hours time-in-service 

(TIS), inspecting each float inflation 

hose port fitting for corrosion, 

condition, or a bend in the tubing, and 

replacing the hose if there is corrosion 

or damage that has penetrated the base 

material more than .010 inch. If there is 

a bend in the tubing greater than 5 

degrees, bending the port fitting back to 

its original position. Installing a 

marking label on each port fitting which 

states ‘‘AFT FLOAT.’’ 

• Within 6 months, installing a port 

fitting adapter on each port fitting and 

replacing each aft float hose. 

Differences Between This Proposed AD 

and the Service Information 

The ASB requires installing the port 

fitting adapter and replacing the aft hose 

by a specific calendar date, while the 

proposed AD requires these actions be 

accomplished within 6 months. 

Costs of Compliance 

We estimate that this proposed AD 

would affect 265 helicopters of U.S. 

Registry. Based on an average labor rate 

of $85 per hour, we estimate that 

operators may incur the following costs 

in order to comply with this AD. 

Inspecting the float inflation hoses and 

installing the marking labels will 

require about 1 work hour, and required 

parts will cost about $2, for a cost per 

helicopter of $87, and a total cost to U.S. 

operators of $23,055. Installing the port 

fitting adaptor and replacing the aft float 

hose assembly will require about 1 work 

hour, and required parts will cost about 

$165, for a cost per helicopter of $250. 

Thus, we estimate a total cost to U.S. 

operators of $89,305. 

If any fitting has excessive corrosion 

or damage, replacing the fitting will 

require about 1 work hour, and required 

parts will cost about $125, for a cost per 

helicopter of $210. 

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, I certify 

this proposed regulation: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 


TKELLEY on DSK3SPTVN1PROD with PROPOSALS
33772 Federal Register / Vol. 78, No. 108 / Wednesday, June 5, 2013 / Proposed Rules 

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 to the extent that it justifies 

making a regulatory distinction; 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. 

We prepared an economic evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.
