Airworthiness Directives; Dassault Model Falcon 2000 Series 
Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
is applicable to all Dassault Model Falcon 2000 series airplanes. This 
action requires installing new placards that stipulate the use of 
certain types of fuels, and revising the Airplane Flight Manual to 
specify the appropriate types of fuels for use in the affected 
airplanes. This amendment is prompted by a report indicating that, due 
to use of certain fuels, engine flame-out may occur. The actions 
specified in this AD are intended to ensure that certain fuels are 
prohibited from use; use of these fuels could cause an engine flame-out 
during a rapid throttle reduction.

DATES: Effective September 29, 1997.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of October 14, 1997.
    Comments for inclusion in the Rules Docket must be received on or 
before November 12, 1997.

ADDRESSES: Submit comments in triplicate to the Federal Aviation 
Administration (FAA), Transport Airplane Directorate, ANM-103,

SUPPLEMENTARY INFORMATION: The Direction Generale de l'Aviation Civile 
(DGAC), which is the airworthiness authority for France, notified the 
FAA that an unsafe condition may exist on all Dassault Model Falcon 
2000 series airplanes. The DGAC advises that results of bench testing 
revealed that the use of JET B or JP4 fuel (or equivalent fuels) could 
result in an engine flame-out during rapid throttle reduction. Such 
engine flame-out during rapid throttle reduction.

Explanation of Relevant Service Information

    Dassault has issued Service Bulletin F2000-80 (F2000-28-3), dated 
December 11, 1996, which describes procedures for installing new 
placards stipulating the use of certain types of fuels. The service 
bulletin also describes procedures for incorporating Temporary Change 
No. 34 (undated) to the Falcon 2000 Airplane Flight Manual (AFM), into 
the AFM. Temporary Change No. 34 specifies the appropriate types of 
fuels in Model Falcon 2000 series airplanes. The DGAC classified this 
service bulletin as mandatory, and issued French airworthiness 
directive 96-290-001(B), dated December 4, 1996, in order to assure the 
continued airworthiness of these airplanes in France.

FAA's Conclusions

    This airplane model is manufactured in France and is type 
certificated for operation in the United States under the provisions of 
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and 
the applicable bilateral airworthiness agreement. Pursuant to this 
bilateral airworthiness agreement, the DGAC has kept the FAA informed 
of the situation described above. The FAA has examined the findings of 
the DGAC, 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.

Explanation of Requirements of Rule

    Since an unsafe condition has been identified that is likely to 
exist or develop on other airplanes of the same type design registered 
in the United States, this AD is being issued to prevent an engine 
flame-out during a rapid throttle reduction. This AD requires 
installing new placards that stipulate the use of certain types of 
fuels, and revising the Limitations and Abnormal Procedures Sections of 
the FAA-approved AFM to specify the appropriate types of fuels for use 
in the affected airplanes. Those actions are required to be 
accomplished in accordance with the service bulletin described 
previously.

Determination of Rule's Effective Date

    Since a situation exists that requires the immediate adoption of 
this regulation, it is found that notice and opportunity for prior 
public comment hereon are impracticable, and that good cause exists for 
making this amendment effective in less than 30 days.

Comments Invited

    Although this action is in the form of a final rule that involves 
requirements affecting flight safety and, thus, was not preceded by 
notice and an opportunity for public comment, comments are invited on 
this rule. Interested persons

[[Page 47932]]

are invited to comment on this rule by submitting such written data, 
views, or arguments as they may desire. Communications shall identify 
the Rules Docket number and be submitted in triplicate to the address 
specified under the caption ADDRESSES. All communications received on 
or before the closing date for comments will be considered, and this 
rule may be amended in light of the comments received. Factual 
information that supports the commenter's ideas and suggestions is 
extremely helpful in evaluating the effectiveness of the AD action and 
determining whether additional rulemaking action would be needed.
    Comments are specifically invited on the overall regulatory, 
economic, environmental, and energy aspects of the rule that might 
suggest a need to modify the rule. All comments submitted will be 
available, both before and after the closing date for comments, in the 
Rules Docket for examination by interested persons. A report that 
summarizes each FAA-public contact concerned with the substance of this 
AD will be filed in the Rules Docket.
    Commenters wishing the FAA to acknowledge receipt of their comments 
submitted in response to this rule must submit a self-addressed, 
stamped postcard on which the following statement is made: ``Comments 
to Docket Number 97-NM-182-AD.'' The postcard will be date stamped and 
returned to the commenter.

Regulatory Impact

    The regulations adopted herein will not have substantial direct 
effects 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, in 
accordance with Executive Order 12612, it is determined that this final 
rule does not have sufficient federalism implications to warrant the 
preparation of a Federalism Assessment.
    The FAA has determined that this regulation is an emergency 
regulation that must be issued immediately to correct an unsafe 
condition in aircraft, and that it is not a ``significant regulatory 
action'' under Executive Order 12866. It has been determined further 
that this action involves an emergency regulation under DOT Regulatory 
Policies and Procedures (44 FR 11034, February 26, 1979). If it is 
determined that this emergency regulation otherwise would be 
significant under DOT Regulatory Policies and Procedures, a final 
regulatory evaluation will be prepared and placed in the Rules Docket. 
A copy of it, if filed, may be obtained from the Rules Docket at the 
location provided under the caption ADDRESSES.
