Federal Register Abstract
We are adopting a new airworthiness directive (AD) for certain Bell Helicopter Textron, Inc. (Bell), Model 204B, 205A, 205A-1, and 212 helicopters. This AD requires removing a certain part-numbered main rotor (M/R) blade grip (grip) from service. This AD is prompted by an error in a parts manufacturer approval (PMA) that incorrectly allows installation of the grips on the Bell Model 212. The actions specified in this AD are intended to prevent grip failure, separation of the M/R blade, and subsequent loss of control of the helicopter.

SUPPLEMENTARY INFORMATION:
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not provide you with notice and an opportunity to
provide your comments prior to it becoming effective. However, 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 resulted
from adopting this AD. The most helpful comments reference a specific
portion of the AD, 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 them 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 rulemaking during the
comment period. We will consider all the comments we receive and may
conduct additional rulemaking based on those comments.

Discussion
We are adopting a new AD for Bell Model 204B, 205A, 205A-1, and 212
helicopters with a grip part number (P/N) ASI-4011-121-113 installed.
This AD requires removing any grip from service if the grip is
currently or has ever been installed on a Bell Model 212 helicopter, or
if it is unknown whether the grip has ever been installed on a Model
212 helicopter. This AD also prohibits installing grip P/N ASI-4011-
121-113 on any helicopter if the grip has ever been installed on a Bell
Model 212 helicopter. This AD is prompted by an error in the PMA that
allows installing the subject grip on the Bell Model 212.
Grip P/N ASI-4011-121-113 is currently produced by Timken Alcor
Aerospace Technologies, Inc., under a PMA as a replacement grip for
Bell P/N 204-011-121-113. This approval incorrectly listed grip P/N
ASI-4011-121-113 as eligible for installation on Bell Model 212
helicopters. The PMA has been revised to remove that eligibility. This
grip was previously produced and sold as a replacement grip for Bell P/
N 204-011-121-113 by Air Services International of Scottsdale, AZ, as
P/N ASI-4011-121-113. The actions required in this AD are intended to
prevent installation of an unapproved grip, which could result in grip
failure, separation of the M/R blade, and subsequent loss of control of
the helicopter.
FAA's Determination
We are issuing this AD because we evaluated all known relevant
information and determined that the unsafe condition described
previously is likely to exist in other products of these same type
designs.
Related Service Information
We reviewed Timken T-700 Service Bulletin, Revision B, dated
October 20, 2014. The service bulletin specifies the airworthiness life
limitations and inspection interval schedule for various Timken Alcor
Aerospace Technologies, Inc., replacement parts and articles.
AD Requirements
This AD requires, within 5 hours time-in-service (TIS), removing
any grip P/N ASI-4011-121-113 from service if the grip is currently or
has ever been installed on a Bell Model 212 helicopter. This AD also
prohibits installing a grip P/N ASI-4011-121-113 on any helicopter if
the grip is currently or has ever been installed on a Bell Model 212
helicopter.
Differences Between This AD and the Service Information
The Timken service bulletin provides the airworthiness limitations
and inspection intervals for various life limited parts, including grip
P/N ASI-4011-121-113. This AD only applies to helicopters with grip P/N
ASI-4011-121-113 and requires removing the grip from service if it is
currently or has ever been installed on a Bell Model 212 helicopter.
Costs of Compliance
We estimate that this AD could affect 130 helicopters of U.S.
Registry. We estimate that operators may incur the following costs in
order to comply with this AD. It takes about 20 work-hours to replace
two M/R grips per helicopter. We estimate an average labor rate of $85
per work-hour, and a required parts cost of approximately $56,385 for
two grips. Based on these figures, we estimate a total cost of $58,085
per helicopter and $7,551,050 for the U.S. fleet.
FAA's Justification and Determination of the Effective Date
Providing an opportunity for public comments prior to adopting
these AD requirements would delay implementing the safety actions
needed to correct this known unsafe condition. Therefore, we find that
the risk to the flying public justifies waiving notice and comment
prior to the adoption of this rule because the unsafe condition can
adversely affect control of the helicopter and the required corrective
actions must be accomplished within 5 hours TIS.
Since an unsafe condition exists that requires the immediate
adoption of this AD, we determined that notice and opportunity for
public comment before issuing this AD are impracticable and contrary to
the public interest and that good cause exists for making this
amendment effective in less than 30 days.
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 AD would not have federalism implications
under Executive Order 13132. This 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 that this AD:
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 AD and placed it in the AD docket.
