Airworthiness Directives; Bell Helicopter Textron, Inc. 
Helicopters

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, 206L-4, and 407 helicopters with an Apical Industries, Inc. 
(Apical) emergency float kit installed under supplemental type 
certificate (STC) number SR01535LA. This proposed AD would require 
inspecting, labeling, and replacing the float inflation hoses. This 
proposed AD is prompted by an incident in which the floats installed on 
a helicopter failed to deploy. The proposed actions are intended to 
prevent failure of the emergency floatation gear to deploy during an 
emergency event.

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;

[[Page 33772]]

    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.
