[[Page 59778]]
EC 155B helicopters with certain SMD45H multi-functional displays. This
action requires replacing the ``AC'' SMD45H multi-functional display
interconnection board (interconnection board) of the affected displays
with a ``BC'' interconnection board. This amendment is prompted by an
incident of smoke in a cockpit caused by overheating of the
interconnection board. The actions specified in this AD are intended to
prevent an electrical discontinuity in the grounding plane inside the
SMD45H multi-functional display, which can result in overheating of the
interconnection board, smoke in the cockpit, and subsequent loss of
control of the helicopter.
DATES: Effective October 9, 2002.
Comments for inclusion in the Rules Docket must be received on or
before November 25, 2002.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), Office of the Regional Counsel, Southwest Region,
Attention: Rules Docket No. 2002-SW-11-AD, 2601 Meacham Blvd., Room

FOR FURTHER INFORMATION CONTACT: Jorge Castillo, Aviation Safety
Engineer, FAA, Rotorcraft Directorate, Rotorcraft Standards Staff, Fort
Worth, Texas 76193-0110, telephone (817) 222-5127, fax (817) 222-5961.
SUPPLEMENTARY INFORMATION: The Direction Generale De L'Aviation Civile
(DGAC), which is the airworthiness authority for France, notified the
FAA that an unsafe condition may exist on Eurocopter Model EC 155B
helicopters. The DGAC advises that a manufacturing anomaly on the
``AC'' interconnection board of certain display screens might cause
discontinuity inside the grounding plane and result in overheating of
the board and smoke in the cockpit. One case of smoke in the cockpit
occurred at the manufacturer's facility.
Eurocopter has issued Alert Telex No. 04A004, dated November 22,
2001, which specifies replacement of SMD45H screens equipped with
interconnection boards that might show some non-conformities with the
manufacturing requirements. The DGAC classified this alert telex as
mandatory and issued AD 2001-617-004(A), dated December 26, 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 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 an electrical
discontinuity inside the grounding plane, which can result in
overheating of the interconnection board, smoke in the cockpit, and
subsequent loss of control of the helicopter. This AD requires, within
30 days after the effective date of this AD, replacing the ``AC''
interconnection board of the affected displays with a ``BC''
interconnection board. The short compliance time involved is required
because the previously described critical unsafe condition can
adversely affect the controllability or structural integrity of the
helicopter. Therefore, replacing the ``AC'' interconnection board of
the affected displays with a ``BC'' interconnection board is required
within 30 days, 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 2 helicopters will be affected by this AD,
that it will take approximately 1 work hour to accomplish the
interconnection board replacement, and that the average labor rate is
$60 per work hour. Required parts cost approximately $200 per
helicopter. Based on these figures, the total cost impact of the AD on
U.S. operators is estimated to be $520.
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. 2002-SW-11-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.
