Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2008-0039; Directorate Identifier 2006-SW-13-AD; 
Amendment 39-15596; AD 2008-14-01]
RIN 2120-AA64


Airworthiness Directives; Bell Helicopter Textron Canada Model 
222, 222B, 222U, 230 and 430 Helicopters

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD) for 
Bell Helicopter Textron Canada (BHTC) Model 222, 222B, 222U, 230 and 
430 helicopters that requires rewiring and testing the fuel valve 
switch on each engine and testing the ignitor system. This amendment is 
prompted by an in-flight incident in which a fuel valve switch failed, 
causing the fuel valve to inadvertently close. The actions specified by 
this AD are intended to prevent interruption of the fuel supply caused 
by failure of the fuel switch, which could result in loss of engine 
power and subsequent loss of control of the helicopter.

DATES: Effective August 14, 2008.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of August 14, 2008.

ADDRESSES: You may get the service information identified in this AD 
from Bell Helicopter Textron Canada, 12,800 Rue de l'Avenir, Mirabel, 
Quebec J7J1R4, telephone (450) 437-2862 or (800) 363-8023, fax (450) 
433-0272.
    Examining the Docket: You may examine the docket that contains this 
AD, any comments, and other information on the Internet at http://www.regulations.gov, or at the Docket Operations office, West Building 
Ground Floor, Room W12-140, 1200 New Jersey Avenue, SE., Washington, 
DC.

FOR FURTHER INFORMATION CONTACT: George Schwab, Aviation Safety 
Engineer, FAA, Rotorcraft Directorate, Safety Management Group, Fort 
Worth, Texas 76193-0110, telephone (817) 222-5114, fax (817) 222-5961.

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 January 23, 2008 (73 FR 3889). That action proposed 
to require, within 50 hours time-in-service (TIS), rewiring the 
switches that control the operation of the No. 1 and No. 2 engines' 
fuel valves, and testing the switches and the ignitor system.
    Transport Canada, the airworthiness authority for Canada, notified 
the FAA that an unsafe condition may exist on BHTC Model 222, 222B, 
222U, 230 and 430 helicopters. Transport Canada advises of an 
investigation into an incident involving a BHTC Model 222 helicopter, 
in which the fuel shut-off switch, part number (P/N) 10648BH1-1, failed 
during flight causing the fuel valve to close and the engine to shut 
down. Review of the Service Difficulty Report database identified two 
other incidents of switch failure.
    Bell Helicopter Textron has issued the following technical 
bulletins, all dated June 11, 2003, which specify rewiring the fuel 
valve switch:

------------------------------------------------------------------------
            Technical bulletin               Helicopter models affected
------------------------------------------------------------------------
No. 222-03-171............................  Model 222 and 222B
                                             helicopters.
No. 222U-03-96............................  Model 222U helicopters.
No. 230-03-35.............................  Model 230 helicopters.
No. 430-03-33.............................  Model 430 helicopters.
------------------------------------------------------------------------

    Transport Canada classified these technical bulletins as mandatory 
and issued AD No. CF-2006-03, dated February 28, 2006, to ensure the 
continued airworthiness of these helicopters in Canada. That AD 
requires compliance no later than May 3, 2006. This AD requires 
compliance within 50 hours TIS.
    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 this type design 
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 this AD will affect 165 helicopters of U.S. 
registry, and the required actions will take approximately four work 
hours per helicopter to rewire the 2 fuel valve switches, and test 
those switches and the ignitor system, at an average labor rate of $80 
per work hour. Based on these figures, we estimate the total cost 
impact of the AD on U.S. operators to be $52,800 ($320 per helicopter).

Regulatory Findings

    We have determined that this AD will not have federalism 
implications under Executive Order 13132. This AD 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.
    For the reasons discussed above, I certify that the regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this AD. See the AD docket to examine the economic evaluation.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. Subtitle VII, Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, section 44701, ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.
