Airworthiness Directives; Bell Helicopter Textron Canada Model 
222, 222B, and 222U 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 August 12, 2003.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of August 12, 2003.

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

FOR FURTHER INFORMATION CONTACT: Charles Harrison, Aviation Safety 
Engineer, FAA, Rotorcraft Directorate, Safety Management Group, Fort 
Worth, Texas 76193-0110, telephone (817) 222-5128, fax (817) 222-5961.

SUPPLEMENTARY INFORMATION: A proposal to amend 14 CFR part 39 to 
include an AD for Bell Model 222, 222B, and 222U helicopters was 
published in the Federal Register on February 7, 2003 (68 FR 6383). 
That action proposed to require inspecting the adjustable stop screws 
of the magnetic brake assembly to ensure they are installed correctly; 
repairing the arm assembly, if necessary; 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 222, 222B, and 
222U helicopters with Instrument Flight Rule (IFR) kits, part number 
(P/N) 222-706-013, installed, and all delivered spare magnetic brakes, 
P/N 222-706-013, manufactured by Memcor Truohm, Inc., under 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 Bell Helicopter Textron Alert Service Bulletin 
(ASB) No. 222-01-87, for Model 222 and 222B helicopters, and ASB No. 
222U-01-58, for Model 222U helicopters, both dated January 19, 2001. 
Both ASB's specify a one-time inspection of the magnetic brake 
adjustable stop screw, P/N M551959-3; 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 these ASB's as mandatory and issued AD No. 
CF-2002-17, dated March 4, 2002, to ensure the continued airworthiness 
of these helicopters in Canada.

    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.
    On July 10, 2002, the FAA issued a new version of 14 CFR part 39 
(67 FR 47997, July 22, 2002), which governs the FAA's airworthiness 
directives system. The regulation now includes material that relates to 
altered products, special flight permits, and alternative methods of 
compliance. However, for clarity and consistency in this final rule, we 
have retained the language of the NPRM regarding that material.
    The FAA estimates that 92 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 $60 per work hour. Required parts will cost approximately 
$3,785. Based on these figures, the total cost impact of the AD on U.S. 
operators is estimated to be $364,780, assuming all parts are replaced.
    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 
ADDRESSES.
