Airworthiness Directives; Eurocopter France Model AS332L2 
Helicopters

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

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.

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.
