FOR FURTHER INFORMATION CONTACT: Carroll Wright, Aviation Safety
Engineer, FAA, Rotorcraft Directorate, Regulations Group, Fort Worth,
Texas 76193-0111, telephone (817) 222-5120, fax (817) 222-5961.
SUPPLEMENTARY INFORMATION: Transport Canada, the airworthiness
authority for Canada, notified the FAA that an unsafe condition may
exist on ECF Model AS350BA and B2 helicopters. Transport Canada advises
of an incident involving an ECF Model AS350 helicopter, equipped with
an ECL Left-Side Pilot Configuration kit, Canadian STC SH96-32 or
United States STC SR00429 NY, in which the collective locking device
engaged during flight.
ECL has issued Service Bulletin AS 350 BA, B2, No. ECL-99-67-002,
Revision 2, dated September 23, 1999, which specifies replacing the
collective locking device with a locking device that eliminates
inadvertent engagement. Transport Canada classified this service
bulletin as mandatory and issued AD No. CF-2000-06R1, dated August 23,
2000, to ensure the continued airworthiness of these helicopters in
Canada.
These helicopter models are manufactured in France and are type
certificated for operation in the United States under the provisions of
14 CFR 21.29 and the applicable bilateral agreement. The Left-Side
Pilot Configuration kit was installed by ECL. Pursuant to the
applicable bilateral agreement, Transport Canada has kept the FAA
informed of the situation described above. The FAA has examined the
findings of Transport Canada, reviewed all available information, and
determined that AD action is necessary for products of these type
designs that are certificated for operation in the United States.
This unsafe condition is likely to exist or develop on other
helicopters of the same type design registered in the United States.
Therefore, this AD is being issued to prevent inadvertent engagement of
a collective locking device, the collective control locking in the
full-down position, and subsequent loss of control of the helicopter.
The actions must be accomplished in accordance with the service
bulletin described previously. The short compliance time involved is
required because the previously described critical unsafe condition can
adversely affect the controllability of the helicopter. Therefore,
replacing the locking device with a new locking device within 50 hours
time-in-service or 30 days, whichever occurs first, is required, and
this AD must be issued immediately.
Since a situation exists that requires the immediate adoption of
this regulation, it is found that notice and opportunity for prior
public comment hereon are impracticable, and that good cause exists for
making this amendment effective in less than 30 days.
The FAA estimates that 28 helicopters will be affected by this AD,
that it will take approximately 5 work hours to install a locking
device and that the average labor rate is $60 per work hour. ECL has
represented to the FAA that for each Left-Side Pilot Configuration
delivered with a previous version of the collective locking device, one
set of applicable parts specified in the service bulletin will be made
available free of charge. Based on these figures, the total cost impact
of the AD on U.S. operators is estimated to be $8,400.
Comments Invited
Although this action is in the form of a final rule that involves
requirements affecting flight safety and, thus, was not preceded by
notice and an opportunity for public comment, comments are invited on
this rule. Interested persons are invited to comment on this rule by
submitting such written data, views, or arguments as they may desire.
Communications should identify the Rules Docket number and be submitted
in triplicate to the address specified under the caption ADDRESSES. All
communications received on or before the closing date for comments will
be considered, and this rule may be amended in light of the comments
received. Factual information that supports the commenter's ideas and
suggestions is extremely helpful in evaluating the effectiveness of the
AD action and determining whether additional rulemaking action would be
needed.
Comments are specifically invited on the overall regulatory,
economic, environmental, and energy aspects of the rule that might
suggest a need to modify the rule. All comments submitted will be
available in the Rules Docket for examination by interested persons. A
report that summarizes each FAA-public contact concerned with the
substance of this AD will be filed in the Rules Docket.
Commenters wishing the FAA to acknowledge receipt of their mailed
comments submitted in response to this rule must submit a self-
addressed, stamped postcard on which the following statement is made:
``Comments to Docket No. 2001-SW-62-AD.'' The postcard will be date
stamped and returned to the commenter.
The regulations adopted herein will 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. Therefore, it
is determined that this final rule does not have federalism
implications under Executive Order 13132.
The FAA has determined that this regulation is an emergency
regulation that must be issued immediately to correct an unsafe
condition in aircraft, and that it is not a ``significant regulatory
action'' under Executive Order 12866. It has been determined further
that this action involves an emergency regulation under DOT Regulatory
Policies and Procedures (44 FR 11034, February 26, 1979). If it is
determined that this emergency regulation otherwise would be
significant under DOT Regulatory Policies and Procedures, a final
regulatory evaluation will be prepared and placed in the Rules Docket.
A copy of it, if filed, may be obtained from the Rules Docket at the
location provided under the caption ADDRESSES.
