SUMMARY: This amendment adopts a new airworthiness directive (AD) for
Eurocopter France (Eurocopter) Model AS332L2 helicopters. This action
requires removing the main rotor shaft non-rotating scissors (non-
rotating scissors) from the swashplate balljoint and inspecting for
friction or play in the hinges between the two links of the non-
rotating scissors, or between the non-rotating scissors link and the
flared housing, and replacing the non-rotating scissors, if necessary.
This amendment is prompted by the discovery of in-service damage to
main rotor shaft non-rotating scissors attachment hinges. The actions
specified in this AD are intended to prevent friction on non-rotating
scissors, failure of the swashplate, loss of main rotor pitch control,
and subsequent loss of control of the helicopter.
DATES: Effective June 27, 2002.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of June 27, 2002.
Comments for inclusion in the Rules Docket must be received on or
before August 12, 2002.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), Office of the Regional Counsel, Southwest Region,

FOR FURTHER INFORMATION CONTACT: Jim Grigg, Aviation Safety Engineer,
FAA, Rotorcraft Directorate, Rotorcraft Standards Staff, Fort Worth,
Texas 76193-0110, telephone (817) 222-5490, fax (817) 222-5961.
SUPPLEMENTARY INFORMATION: The Direction Generale De L'Aviation Civile
(DGAC), the airworthiness authority for France, notified the FAA that
an unsafe condition may exist on Eurocopter Model AS332L2 helicopters.
The DGAC advises that some cases of in-service damage to the main rotor
shaft non-rotating scissors attachment hinge have been discovered.
Eurocopter has issued Eurocopter Alert Service Bulletin No.
05.00.56, dated February 1, 2001, which specifies a check of the non-
rotating scissors hinges on the main rotor shaft for evidence of
seizure on the interface of the various tungsten-carbide bushings of
the hinges that may lead to the seizure of a hinge. The DGAC classified
this service bulletin as mandatory and issued AD 2001-085-018(A), dated
March 7, 2001, to ensure the continued airworthiness of these
helicopters in France.
This helicopter model is manufactured in France and is type
certificated for operation in the United States under the provisions of
14 CFR 21.29 and the applicable bilateral agreement. Pursuant to the
applicable bilateral agreement, the DGAC has kept the FAA informed of
the situation described above. The FAA has examined the findings of the
DGAC, reviewed all available information, and determined that AD action
is necessary for products of this type design that may be certificated
for operation in the United States at a future date.
This unsafe condition is likely to exist or develop on other
helicopters of the same type design if registered in the United States.
Therefore, this AD is being issued to prevent friction on the non-
rotating scissors, failure of the swashplate, loss of main rotor pitch
control, and subsequent loss of control of the helicopter. This AD
requires removing the non-rotating scissors from the swashplate
balljoint and inspecting for friction or play in the hinges between the
two links of the non-rotating scissors, or between the non-rotating
scissors link and the flared housing, and replacing the non-rotating
scissors if friction or play is detected. The actions must be
accomplished in accordance with the service bulletin described
previously.
None of the Eurocopter Model AS332L2 helicopters affected by this
action are on the U.S. Register. All helicopters included in the
applicability of this rule are currently operated by non-U.S. operators
under foreign registry; therefore, they are not directly affected by
this AD action. However, the FAA considers that this rule is necessary
to ensure that the unsafe condition is addressed in the event that any
of these subject helicopters are imported and placed on the U.S.
Register in the future.
Should an affected helicopter be imported and placed on the U.S.
Register in the future, it would require approximately 6 work hours to
accomplish the required actions, at an average labor rate of $60 per
work hour. Based on these figures, the cost impact of this AD would be
$360 per helicopter.
Since this AD action does not affect any helicopter that is
currently on the U.S. register, it has no adverse economic impact and
imposes no additional burden on any person. Therefore, notice and
public procedures hereon are unnecessary and the amendment may be made
effective in less than 30 days after publication in the Federal
Register.
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-63-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 notice and prior public comment are
unnecessary in promulgating this regulation; therefore, it can be
issued immediately to correct an unsafe condition in aircraft since
none of these model helicopters are registered in the United States.
The FAA has also determined that this regulation 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.
