    SUPPLEMENTARY INFORMATION:

    The Direction Générale de l'Aviation Civile (DGAC), which is the airworthiness authority for France recently notified the FAA that an unsafe condition may exist on all Dassault Model Falcon 10 series airplanes. The DGAC advises that, during routine maintenance, when removing a fire extinguishing bottle that had accidentally discharged, it was Start Printed Page 34086found that the charge from the bottle had been trapped in the discharge line. Investigation revealed that a pin had not been correctly installed in the non-return valve during manufacture. The pin is normally located across the valve body to prevent the shuttle-ball from blocking the outlet to the engine. If the pin is located too close to the edge of the valve body, the shuttle-ball may block the discharge outlet and prevent the charge from releasing into the engine during an engine fire. Such conditions, if not corrected, could result in the inability to extinguish a fire in an engine.

    Explanation of Relevant Service Information

    Dassault has issued Service Bulletin F10-A291, dated June 1, 2001, which describes procedures for an inspection to verify proper installation of the pins in the dual non-return valves of the fire extinguishing system for the engines, and replacement of any defective valve with a new valve. A defective valve is described as any valve with a pin found outside the identified tolerance range. Accomplishment of the actions specified in the service bulletin is intended to adequately address the identified unsafe condition. The DGAC classified this service bulletin as mandatory and issued French airworthiness directive T2001-219-025(B), dated June 1, 2001, 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 failure of a fire extinguisher bottle to discharge, which could result in the inability to extinguish a fire in an engine. This AD requires an inspection to verify proper installation of the pins in the dual non-return valves of the fire extinguishing system for the engines, and replacement of any defective valve with a new valve. The actions are required to be accomplished in accordance with the service bulletin described previously.

    Difference Between This AD, Service Bulletin, and Foreign Airworthiness Directive

    This AD differs from the service bulletin and the parallel French airworthiness directive in that it requires accomplishment of the inspection within 10 days after the effective date of this AD. In developing an appropriate compliance time for this AD, the FAA considered not only the DGAC's recommendation, but the degree of urgency associated with addressing the subject unsafe condition, the average utilization of the affected fleet, and the time necessary to perform the inspection (one hour). In light of all of these factors, the FAA finds a 10-day compliance time for completing the required actions to be warranted, in that it represents an appropriate interval of time allowable for affected airplanes to continue to operate without compromising safety.

    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 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.

    Submit comments using the following format:

    • Organize comments issue-by-issue. For example, discuss a request to change the compliance time and a request to change the service bulletin reference as two separate issues.
    • For each issue, state what specific change to the AD is being requested.
    • Include justification (e.g., reasons or data) for each request.

    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 2001-NM-191-AD.” The postcard will be date stamped and returned to the commenter.

    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.

    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.
