14 CFR Part 39

[Docket No. 99-SW-78-AD; Amendment 39-12560; AD 2001-25-07]
RIN 2120-AA64


Airworthiness Directives; Eurocopter France Model AS 332C, L, L1, 
and L2 Helicopters

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment supersedes an existing airworthiness directive 
(AD) that applies to Eurocopter France Model AS 332C, L, L1, and L2 
helicopters. That AD requires conducting a filter clogging warning 
test, and, if necessary, replacing a jammed valve with an airworthy 
valve. This amendment requires the same actions as the existing AD but 
references a revision to the previously referenced service information; 
adds fuel filter part numbers to the applicability; and clarifies other 
provisions throughout the AD. This amendment is prompted by jammed fuel 
filter by-pass valves. The actions specified by this AD are intended to 
prevent power loss due to fuel starvation, engine flameouts, and a 
subsequent forced landing.

DATES: Effective January 25, 2002.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of January 25, 2002.

ADDRESSES: The service information referenced in this AD may be 
obtained from American Eurocopter Corporation, 2701 Forum Drive, Grand 
Prairie, Texas 75053-4005, telephone (972) 641-3460, fax (972) 641-
3527. 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, Rotorcraft Standards Staff, Fort Worth, 
Texas 76193-0110, telephone (817) 222-5125, fax (817) 222-5961.

SUPPLEMENTARY INFORMATION: A proposal to amend 14 CFR part 39 by 
superseding AD 99-13-02, Amendment 39-11195 (64 FR 32399, June 17, 
1999), which applies to Eurocopter France Model AS 332C, L, L1, and L2 
helicopters, was published in the Federal Register on April 14, 2000 
(65 FR 20104). That action proposed to require the same actions as AD 
99-13-02 but would have added another fuel filter part number to the 
applicability.
    After issuing that notice of proposed rulemaking (NPRM), Eurocopter 
France issued Alert Service Bulletin No. 01.00.56, dated January 16, 
2001 (ASB), which changed the compliance and operational procedures and 
added a part number to the affected fuel filters. The Direction 
Generale De L'Aviation Civile, which is the airworthiness authority for 
France, classified that ASB as mandatory and issued AD Nos. 1998-318-
071(A)R6 and 1998-319-012(A)R6, both dated April 18, 2001, to ensure 
the continued airworthiness of these helicopters in France. The FAA 
determined that the actions and all the fuel filter part numbers 
specified in the SB should be included in the proposal. Because the 
changes expanded the scope of the originally proposed rule, the FAA 
determined that it was necessary to reopen the comment period to 
provide additional opportunity for public comment and issued a 
supplemental NPRM on August 17, 2001 (66 FR 45651, August 29, 2001).
    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 except for a minor editorial change in 
Note 2 of the AD. The word ``bulletin'' is inserted to reference the 
applicable service information. This change neither increases the 
economic burden on any operator nor increases the scope of the AD.

[[Page 65828]]

    The FAA estimates that one helicopter 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. Based on these figures, the total cost 
impact of the AD on U.S. operators is estimated to be $180, assuming no 
valve needs to be 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
