Airworthiness Directives; Dassault Model Mystere-Falcon 50, 
Mystere-Falcon 900, and Falcon 900 EX Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: This document proposes the adoption of a new airworthiness 
directive (AD) that is applicable to certain Dassault Model Mystere-
Falcon 50, Mystere-Falcon 900, and Falcon 900EX series airplanes. This 
proposal would require installing a shield plate over the tank 
structure above the Stormscope antenna and replacing the Stormscope 
antenna plug connector with a new connector. This action is necessary 
to prevent puncture of the fuel tank, in the event of a belly landing, 
which could result in a post-landing fire if fuel leaking from the tank 
makes contact with the sparks from the airplane sliding on the ground. 
This action is intended to address the identified unsafe condition.

DATES: Comments must be received by March 8, 2004.

Discussion

    The Direction G[eacute]n[eacute]rale de l'Aviation Civile (DGAC), 
which is the airworthiness authority for France, notified the FAA that 
an unsafe condition may exist on Dassault Model Mystere-Falcon 50, 
Mystere-Falcon 900, and Falcon 900EX series airplanes. The DGAC advises 
that the Stormscope antenna connector could puncture the fuel tank 
located above the antenna, in the event of a belly landing. This 
condition, if not corrected, could result in a post-landing fire if 
fuel leaking from the tank makes contact with the sparks from the 
airplane sliding on the ground.

Explanation of Relevant Service Information

    Dassault has issued Service Bulletins F50-404, dated November 6, 
2002 (for Model Mystere-Falcon 50 series airplanes); F900-293, dated 
November 13, 2002 (for Model Mystere-Falcon 900 series airplanes); and 
F900EX-158, dated November 13, 2002 (for Model Falcon 900EX series 
airplanes); which describe procedures for installing a shield plate 
over the tank structure above the Stormscope antenna and replacing the 
Stormscope antenna plug connector with a new connector. Accomplishment 
of the actions specified in the service bulletins is intended to 
adequately address the identified unsafe condition. The DGAC classified 
these service bulletins as mandatory and issued French airworthiness 
directive 2002-569(B), dated November 13, 2002, in order to assure the 
continued airworthiness of these airplanes in France.

FAA's Conclusions

    These airplane models are manufactured in France and are 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 Proposed 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, the proposed AD would require accomplishment of 
the actions specified in the service bulletins described previously, 
except as discussed below.

Difference Between Proposed Rule and Referenced Service Bulletin

    Operators should note that, although the Accomplishment 
Instructions of the referenced service bulletins describe procedures 
for submitting a sheet recording compliance with the service bulletin, 
this proposed AD would not require that action. The FAA does not need 
this information from operators.

Cost Impact

    The FAA estimates that 394 Model Mystere-Falcon 50, Mystere-Falcon 
900, and Falcon 900 EX series airplanes of U.S. registry would be 
affected by this proposed AD, that it would take approximately 8 work 
hours per airplane to accomplish the proposed actions, and that the 
average labor rate is $65 per work hour. Required parts are provided 
free of charge by the manufacturer. Based on these figures, the cost 
impact of the proposed AD on U.S. operators is estimated to be 
$204,880, or $520 per airplane.
    The cost impact figure discussed above is based on assumptions that 
no operator has yet accomplished any of the proposed 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

[[Page 5775]]

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 proposed herein would 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 proposal would not have federalism implications 
under Executive Order 13132.
    For the reasons discussed above, I certify that this proposed 
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) if promulgated, 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 copy of the draft 
regulatory evaluation prepared for this action is contained in the 
Rules Docket. A copy of it may be obtained by contacting the Rules 
Docket at the location provided under the caption ADDRESSES.

The Proposed Amendment

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration proposes to amend 
part 39 of 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:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec. 39.13  [Amended]

    2. Section 39.13 is amended by adding the following new 
airworthiness directive:

Dassault Aviation: Docket 2003-NM-51-AD.

    Applicability: Model Mystere-Falcon 50 series airplanes with a 
Stormscope antenna installed between frames 22 and 23 by Dassault 
modification M2208 or by a DFJ Little Rock modification, except on 
airplanes on which Dassault modification M2838 has been performed; 
and Model Mystere-Falcon 900 and Falcon 900EX series airplanes with 
a Stormscope antenna installed between frames 23 and 24 by Dassault 
modification M2993 or by a DFJ Little Rock modification, except 
airplanes on which Dassault modification M3498 has been performed; 
certificated in any category.
    Compliance: Required as indicated, unless accomplished 
previously.
    To prevent puncture of the fuel tank, in the event of a belly 
landing, which could result in a post-landing fire if fuel leaking 
from the tank makes contact with the sparks from the airplane 
sliding on the ground, accomplish the following:

Install and Replace

    (a) Within 25 months after the effective date of this AD, 
install a shield plate over the tank structure above the Stormscope 
antenna, and replace the Stormscope antenna plug connector with a 
new connector, in accordance with the Accomplishment Instructions of 
the applicable service bulletin listed in Table 1 of this AD.

Reporting Difference

    (b) Although the service bulletins referenced in this AD specify 
to submit certain information to the manufacturer, this AD does not 
include such a requirement.

Alternative Methods of Compliance

    (c) In accordance with 14 CFR 39.19, the Manager, International 
Branch, ANM-116, FAA, Transport Airplane Directorate, is authorized 
to approve alternative methods of compliance for this AD.

    Note 1: The subject of this AD is addressed in French 
airworthiness directive 2002-569(B), dated November 13, 2002.
