RIN 2120-AA64
Airworthiness Directives; Bell Helicopter Textron Canada Model
206L-1 and 206L-3 Helicopters
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD) for
the specified Bell Helicopter Textron Canada (Bell) model helicopters
that requires a one-time inspection of the adjustable stop screws of
the magnetic brake assembly; repairing, as appropriate, certain
mechanical damage to the cyclic and collective flight control magnetic
brake arm assembly (arm assembly), if necessary; and installing the
stop screw with the proper adhesive, adjusting the arm assembly travel
and applying slippage marks. This amendment is prompted by reports that
the magnetic brake adjustable screws have backed out, which limited
travel of the arm assembly. The actions specified by this AD are
intended to detect loose adjustable stop screws, that could result in
limiting the travel of the cyclic and collective arm assembly, and
subsequent loss of control of the helicopter.
DATES: Effective December 7, 2004.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of December 7, 2004.
ADDRESSES: The service information referenced in this AD may be
obtained from Bell Helicopter Textron Canada, 12,800 Rue de l'Avenir,
Mirabel, Quebec J7J1R4, telephone (450) 437-2862 or (800) 363-8023, fax

SUPPLEMENTARY INFORMATION: A proposal to amend 14 CFR part 39 to
include an AD for the specified model helicopters was published in the
Federal Register on May 12, 2004 (69 FR 26325). That action proposed to
require within 100 hours time-in-service or within 90 days, whichever
occurs first, and before installation of an affected magnetic brake, a
one-time inspection of the adjustable stop screws of the magnetic brake
assembly; repairing, as appropriate, certain mechanical damage to the
arm assembly, if necessary; and installing the stop screw with the
proper adhesive, adjusting the arm assembly travel and applying
slippage marks.
Transport Canada, the airworthiness authority for Canada, notified
the FAA that an unsafe condition may exist on Bell Model 206L-1 and
206L-3 helicopters with Instrument Flight Rule (IFR) Kit, part number
(P/N) 206-705-001, -101, or -103, installed, and all delivered spare
magnetic brakes, P/N 204-001-376-003, manufactured by Memcor Truohm,
Inc. as P/N MP 498-3. Transport Canada advises that the stop screws, P/
N MS51959-3, of the magnetic brake, P/N 204-001-376-003 (Memcor Truohm
P/N MP 498-3), were installed without the proper adhesive.
Bell has issued Alert Service Bulletin (ASB) No. 206L-01-122, dated
October 3, 2001, which specifies a one-time inspection of the magnetic
brake adjustable stop screw, P/N MS51959-3; repairing any arm assembly
mechanical damage created by the screws; and installing the stop screw
with the proper adhesive and adjusting the arm assembly shaft travel.
Transport Canada classified this alert service bulletin as mandatory
and issued AD No. CF-2002-16, dated March 4, 2002, to ensure the
continued airworthiness of these helicopters in Canada.
These helicopter models are manufactured in Canada and are 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, 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.
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments were received on the
proposal or the FAA's determination of the cost to the public. The FAA
has determined that air safety and the public interest require the
adoption of the rule as proposed.
The FAA estimates that 577 helicopters of U.S. registry will be
affected by this AD, that it will take approximately 3 work hours per
helicopter to accomplish the required actions, and that the average
labor rate is $65 per work hour. Required parts will cost approximately
$3,785. Based on these figures, the total cost impact of this AD on
U.S. operators is estimated to be $298,500, assuming that 75
helicopters in the U.S. will require the actions described in this AD.
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.
For the reasons discussed above, I certify that this action (1) is
not a ``significant regulatory action'' under Executive Order 12866;
(2) is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and (3) 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. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption
