14 CFR Part 39

[Docket No. 2002-NM-233-AD; Amendment 39-13466; AD 2004-03-22]
RIN 2120-AA64


Airworthiness Directives; Dassault Model Falcon 2000 Series 
Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to certain Dassault Model Falcon 2000 series airplanes, that 
requires modification of the forward ribs of the left and right engine 
pylons to plug holes left open during production. This action is 
necessary to prevent fuel leakage into a ``hot'' section of the engine, 
and consequent propagation of an uncontained engine fire. This action 
is intended to address the identified unsafe condition.

DATES: Effective March 17, 2004.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of March 17, 2004.

ADDRESSES: The service information referenced in this AD may be 
obtained from Dassault Falcon Jet, P.O. Box 2000, South Hackensack, New 
Jersey 07606. This information may be examined at the Federal Aviation 
Administration (FAA), Transport Airplane Directorate, Rules Docket, 
1601 Lind Avenue, SW., Renton, Washington; or at the Office of the 
Federal Register, 800 North Capitol Street, NW., suite 700, Washington, 
DC.

FOR FURTHER INFORMATION CONTACT: Tom Rodriguez, Aerospace Engineer, 
International Branch, ANM-116, FAA, Transport Airplane Directorate,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to include an airworthiness 
directive (AD) that is applicable to certain Dassault Model Falcon 2000 
series airplanes was

[[Page 6534]]

published in the Federal Register on December 4, 2003 (68 FR 67816). 
That action proposed to require modification of the forward ribs of the 
left and right engine pylons to plug holes left open during production.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were submitted in response 
to the proposal or the FAA's determination of the cost to the public.

Conclusion

    We have determined that air safety and the public interest require 
the adoption of the rule as proposed.

Cost Impact

    We estimate that 119 airplanes of U.S. registry will be affected by 
this AD, that it will take approximately 1 work hour per airplane to 
accomplish the required actions, and that the average labor rate is $65 
per work hour. The cost of required parts is minimal. Based on these 
figures, the cost impact of the AD on U.S. operators is estimated to be 
$7,735, or $65 per airplane.
    The cost impact figure discussed above is based on assumptions that 
no operator has yet accomplished any of the requirements of this AD 
action, and that no operator would accomplish those actions in the 
future if this AD were not adopted. The cost impact figures discussed 
in AD rulemaking actions represent only the time necessary to perform 
the specific actions actually required by the AD. These figures 
typically do not include incidental costs, such as the time required to 
gain access and close up, planning time, or time necessitated by other 
administrative actions.

Regulatory Impact

    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.
