Federal Aviation Administration, DOT.
Notice of proposed rulemaking (NPRM).
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Dassault Model Falcon 900 EX and Mystere-Falcon 900 series airplanes. This proposal would require installing an attachment support assembly for the fire extinguishing piping in the baggage compartment. This action is necessary to prevent distortion of the fire extinguishing discharge nozzle as a result of the nozzle not being secure, which could result in poor diffusion of the fire extinguishing agent in the event of a fire in the baggage compartment. This action is intended to address the identified unsafe condition.
Comments must be received by March 3, 2003.

Availability of NPRMs
Any person may obtain a copy of this NPRM by submitting a request to the FAA, Transport Airplane Directorate, ANM-114, Attention: Rules Docket No. 2001-NM-269-AD, 1601 Lind Avenue, SW., Renton, Washington 98055-4056.
The Direction Générale de l'Aviation Civile (DGAC), which is the airworthiness authority for France, notified the FAA that an unsafe condition may exist on certain Dassault Model Falcon 900 EX and Model Mystere-Falcon 900 series airplanes. The DGAC advises of a reported case where, after the fire extinguisher for the baggage compartment discharged, the discharge nozzle for the fire extinguishing piping through which the fire extinguishing agent passes, was found damaged. Distortion of the discharge nozzle occurred at the bulkhead feedthrough at frame 30 because the nozzle was not secure. This condition, if not corrected, could result in poor diffusion of the fire extinguishing agent in the event of a fire in the baggage compartment.
Explanation of Relevant Service Information
Dassault has issued Service Bulletins F900EX-142 (for Model Falcon 900 EX series airplanes) and F900-279 (for Model Mystere-Falcon 900 series airplanes), both dated June 7, 2001, including Service Bulletins Compliance page, which describe procedures for installing an attachment support assembly for the fire extinguishing piping in the baggage compartment, and submitting a compliance report to Dassault. Accomplishment of the actions specified in the applicable service bulletin is intended to adequately address the identified unsafe condition. The DGAC classified these service bulletins as mandatory and issued French airworthiness directive 2001-192-034(B), dated May 16, 2001, in order to assure the continued airworthiness of these airplanes in France.
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 applicable service bulletin described previously.
Differences Between Proposed Rule and Service Bulletin
Operators should note that, although the Accomplishment Instructions of the referenced service bulletin describe procedures for completing and submitting a compliance report, this proposed AD would not require such reporting.
The FAA estimates that 150 airplanes of U.S. registry would be affected by this proposed AD, that it would take approximately 3 work hours per airplane to accomplish the proposed actions, and that the average labor rate is $60 per work hour. Required parts would be provided by the manufacturer at no cost to the operators. Based on these figures, the cost impact of the proposed AD on U.S. operators is estimated to be $27,000, or $180 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 proposed 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.
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 Start Printed Page 4741Flexibility 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.Start List of Subjects

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:Start Part
PART 39—AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
2. Section 39.13 is amended by adding the following new airworthiness directive:
Dassault Aviation: Docket 2001-NM-269-AD.
Applicability: Model Falcon 900 EX and Mystere-Falcon 900 series airplanes, certificated in any category; excluding those airplanes on which the modification specified in Dassault Service Bulletin F900EX-142 (Modification F900 EX M3368), or Dassault Service Bulletin F900-279 (Modification MF900 M3368); both dated June 7, 2001; as applicable; has been done.
This AD applies to each airplane 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 airplanes 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 (b) 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 as indicated, unless accomplished previously.
To prevent distortion of the fire extinguishing discharge nozzle as a result of the nozzle not being secure, which could result in poor diffusion of the fire extinguishing agent in the event of a fire in the baggage compartment, accomplish the following:
(a) Within 7 months or 330 flight hours after the effective date of this AD, whichever comes first, install an attachment support assembly for the fire extinguishing piping in the baggage compartment per paragraphs 2.A. through 2.C. of the Accomplishment Instructions of Dassault Service Bulletin F900EX-142 (for Model Falcon 900 EX series airplanes); or Dassault Service Bulletin F900-279 (for Model Mystere-Falcon F900 series airplanes); both dated June 7, 2001; including Service Bulletins Compliance page; as applicable.
Alternative Methods of Compliance
(b) 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, International Branch, ANM-116, Transport Airplane Directorate, FAA. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, International Branch, ANM-116.
Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the International Branch, ANM-116.
Special Flight Permits
(c) 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 airplane to a location where the requirements of this AD can be accomplished.
The subject of this AD is addressed in French airworthiness directive 2001-192-034(B), dated May 16, 2001.
Issued in Renton, Washington, on January 24, 2003.
