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 212, Model 412, and 
Model 412EP helicopters with an EFS tube assembly part number (P/N) 
412-073-820-101 with a date of manufacture before July 28, 2016. This 
proposed AD is prompted by a report from Bell that an EFS tube assembly 
separated from the valve during a 2-year inflation test. A subsequent 
investigation found that excessive sleeve preset force during 
manufacturing caused cracks in the sleeve of the tube assembly, which 
may result in the EFS float failing to deploy. Bell determined that 
only those EFS tube assemblies with P/N 412-073-820-101 that were 
shipped prior to July 28, 2016, were subject to this manufacturing 
defect. Bell states that because this manufacturing defect is difficult 
to detect, affected EFS tube assemblies in service must be replaced. 
The affected parts were associated with a single Bell supplier that is 
no longer manufacturing the tube assembly.
    Accordingly, this proposed AD would require replacing the EFS tube 
assemblies and would prohibit installing an affected EFS tube assembly 
on any helicopter. We are proposing this AD to prevent installing a 
cracked EFS tube assembly, which could result in failure of the EFS 
floats to deploy during an emergency water landing.

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 helicopters of these same type 
designs.

Related Service Information

    We reviewed Bell Alert Service Bulletin (ASB) 212-11-143 and ASB 
412-11-147, both Revision C and dated December 22, 2016. Each ASB 
describes and illustrates procedures to replace the tube assembly 
within 600 flight hours or by March 31, 2017.

Proposed AD Requirements

    This proposed AD would require, within 300 hours time-in-service 
(TIS), replacing any EFS tube assembly P/N 412-073-820-101 that was 
manufactured before July 28, 2016. This proposed AD would also prohibit 
installing an EFS tube assembly P/N 412-073-820-101 that was 
manufactured before July 28, 2016 on any helicopter.

Differences Between This Proposed AD and the Service Information

    The ASBs require compliance within 600 flight hours or by March 31, 
2017; this proposed AD would require compliance within 300 hours TIS.

Costs of Compliance

    We estimate that this proposed AD would affect 250 helicopters of 
U.S. Registry.
    We estimate that operators may incur the following costs in order 
to comply with this proposed AD. At an average

[[Page 3631]]

labor rate of $85 per hour, replacing a tube assembly would require 
about 6 work-hours and required parts would cost $4,902, for a total 
cost of $5,412 per helicopter and $1,353,000 for the U.S. fleet.
    According to Bell's service information, some of the costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected individuals. We do not control warranty coverage by 
Bell. Accordingly, we have included all costs in our cost estimate.

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;
    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.
