Airworthiness Directives; Bell Helicopter Textron Canada Model 
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 430 helicopters that 
requires calibration of the fuel quantity indicating system. This 
amendment is prompted by an operator report of an inaccurate fuel 
quantity indicating system. The actions specified by this AD are 
intended to prevent an inaccurate fuel quantity indicating system 
reading, engine flameout due to fuel starvation, and a subsequent 
forced landing.

DATES: Effective December 12, 2000.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of December 12, 2000.

ADDRESSES: The service information referenced in this AD may be 
obtained from Bell Helicopter Textron Canada, 12,800 Rue de l'Avenir, 
Mirabel, Quebec JON1LO, telephone (450) 437-2862 or (800) 363-8023, fax 
(450) 433-0272. This information may be examined at the FAA, Office of 
the Regional Counsel, Southwest Region, 2601 Meacham Blvd., Room 663, 
Fort Worth, Texas; or at the Office of the Federal Register, 800 North 
Capitol Street, NW., suite 700, Washington, DC.

FOR FURTHER INFORMATION CONTACT: Paul Madej, Aviation Safety Engineer, 
FAA, Rotorcraft Directorate, Standards Staff, Fort Worth, Texas 76193-
0110, telephone (817) 222-5125, fax (817) 222-5961.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to include an AD for BHTC Model 
430 helicopters was published in the Federal Register on August 9, 2000 
(65 FR 48643). That action proposed to require calibration of the fuel 
quantity indicating system.
    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 50 helicopters of U.S. registry will be 
affected by this AD, that it will take approximately 2 work hours per 
helicopter to accomplish the required actions, and that the average 
labor rate is $60 per work hour. Based on these figures, the total cost 
impact of the AD on U.S. operators is estimated to be $6,000.
    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.

Adoption of the Amendment

    Accordingly, pursuant to the authority delegated to me by the

the Federal Aviation Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

Sec. 39.13  [Amended]

    2. Section 39.13 is amended by adding a new airworthiness directive 
to read as follows:

2000-22-13   Bell Helicopter Textron Canada: Amendment 39-11959. 
Docket No. 2000-SW-11-AD.

    Applicability: Model 430 helicopters, serial numbers 49001 
through 49059, certificated in any category.

    Note 1: This AD applies to each helicopter identified in the 
preceding applicability provision, regardless of whether it has been 
otherwise modified, altered, or repaired in the area subject to the 
requirements of this AD. For helicopters that have been modified, 
altered, or repaired so that the performance of the requirements of 
this AD is affected, the owner/operator must request approval for an 
alternative method of compliance in accordance with paragraph (c) of 
this AD. The request should include an assessment of the effect of 
the modification, alteration, or repair on the unsafe condition 
addressed by this AD; and if the unsafe condition has not been 
eliminated, the request should include specific proposed actions to 
address it.

    Compliance: Required at the next scheduled fuel system 
calibration or at the next annual inspection, whichever occurs 
first, unless accomplished previously.
    To prevent an inaccurate fuel quantity indicating system 
reading, engine flameout due to fuel starvation, and a subsequent 
forced landing, accomplish the following:
    (a) Calibrate the fuel quantity indicating system in accordance 
with steps 1 through 21 of the Accomplishment Instructions, Bell 
Helicopter Textron Alert Service Bulletin No. 430-99-13, dated 
December 13, 1999 (ASB).
    (b) Insert BHT-430-MM-10, Chapter 95, Revision 2, dated December 
10, 1999, into the Maintenance Manual.
    (c) An alternative method of compliance or adjustment of the 
compliance time that provides an acceptable level of safety may be 
used if approved by the Manager, Regulations Group, Rotorcraft 
Directorate, FAA. Operators shall submit their requests through an 
FAA Principal Maintenance Inspector, who may concur or comment and 
then send it to the Manager, Regulations Group.

    Note 2: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Regulations Group.

    (d) Special flight permits may be issued in accordance with 
sections 21.197 and 21.199 of the Federal Aviation Regulations (14 
CFR 21.197 and 21.199) to operate the helicopter to a location where 
the requirements of this AD can be accomplished.
    (e) Calibrate the fuel quantity indicating system in accordance 
with steps 1 through 21 of the Accomplishment Instructions, Bell 
Helicopter Textron Alert Service Bulletin No. 430-99-13, dated 
December 13, 1999. This incorporation by reference was approved by 
the Director of the Federal Register in accordance with 5 U.S.C. 
552(a) and 1 CFR part 51. Copies may be obtained from Bell 
Helicopter Textron Canada, 12,800 Rue de l'Avenir, Mirabel, Quebec
