The Direction Generale 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 Mystere-Falcon 200 series airplanes. The DGAC advises that, during a maintenance visit, it was discovered that the fire extinguishing pipes for both engines did not have the holes necessary to disperse fire extinguishing agent. This condition, if not corrected, could result in inability to extinguish an engine fire, should one occur, and consequent loss of control of the airplane.
Explanation of Relevant Service Information
Dassault has issued Alert Service Bulletin F200-A120, Revision 1, dated November 13, 2003. That service bulletin describes procedures for a one-time general visual inspection of the fire extinguishing pipe for each engine to determine whether six holes for dispersal of fire-extinguishing agent are present between the rear coupling and the front attaching lug of the pipe, and corrective action if necessary. If the holes are not present, corrective action includes replacing the fire extinguishing pipe with a new pipe that has the necessary holes, or drilling the necessary holes in the existing pipe. Accomplishment of the action 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 emergency airworthiness directive F-2003-419(B), dated November 13, 2003, to ensure 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 ensure that the flightcrew is able to extinguish an engine fire, should one occur. Inability to extinguish an engine fire could result in loss of control of the airplane. This AD requires a one-time inspection of the fire extinguishing pipe for each engine to determine whether holes for dispersal of fire-extinguishing agent are present, and corrective action if necessary. The actions are required to be accomplished in accordance with the service bulletin described previously, except as discussed below.
Difference Between AD, Service Bulletin, and French Airworthiness Directive
Operators should note that, although the referenced service bulletin and French emergency airworthiness directive specify that the inspection of the fire extinguishing pipes must be accomplished before further flight, this AD requires that this inspection be accomplished within 10 days after the effective date of this AD. In developing an appropriate compliance time for this AD, we considered not only the manufacturer's and DGAC's recommendation, but the degree of urgency associated with addressing the subject unsafe condition, and the time necessary to perform the inspection. In light of all of these factors, we find a compliance time of 10 days represents an appropriate interval of time for affected airplanes to continue to operate without compromising safety. This issue has been coordinated with the DGAC, and they have no objection.
Operators should note that, although the Accomplishment Instructions of the referenced service bulletin describeprocedures for completing a card recording compliance with the service bulletin and submitting it to the manufacturer, this AD does not require those actions.
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 receivedon 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 2003-NM-247-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.
