Final rule; request for comments.
This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2000-01-51 that was sent previously by individual notices to all known U.S. owners and operators of Model CL-604 variant of Bombardier Model Canadair CL-600-2B16 series airplanes modified in accordance with Supplemental Type Certificate SA8060NM-D, SA8072NM-D, or SA8086NM-D. This AD requires that the fuel service panel maintenance light be disconnected. This action is prompted by a report indicating that an electrical spark was noted when the fuel cap chain contacted the maintenance light housing of the fuel service panel. The actions specified by this AD are intended to prevent electrical sparks from a grounded object from coming into contact with the maintenance light housing of the fuel service panel, which could result in a fuel fire due to the close proximity of the fuel service panel to the fuel port.
January 26, 2000, to all persons except those persons to whom it was made immediately effective by emergency AD 2000-01-51, issued January 7, 2000, which contained the requirements of this amendment.
Comments for inclusion in the Rules Docket must be received on or before March 21, 2000.

On January 7, 2000, the FAA issued emergency AD 2000-01-51, which is applicable to the Model CL-604 variant of Bombardier Model Canadair CL-600-2B16 series airplanes modified in accordance with Supplemental Type Certificate SA8060NM-D, SA8072NM-D, or SA8086NM-D.
That action was prompted by a report indicating that an electrical spark was noted when the fuel cap chain contacted the maintenance light housing of the fuel service panel on a CL-604 variant of a Bombardier Model Canadair CL-600-2B16 series airplane. Investigation revealed that the power and ground wires to the fuel service panel light assembly were reversed. Electrical sparks from a grounded object may come into contact with the maintenance light housing of the fuel service panel, and could result in a fuel fire due to the close proximity of the fuel service panel to the fuel port.
Explanation of Requirements of the Rule
Since the unsafe condition described is likely to exist or develop on other airplanes of the same type design, the FAA issued emergency AD 2000-01-51 to prevent electrical sparks from a grounded object from coming into contact with the maintenance light housing of the fuel service panel, which could result in a fuel fire due to the close proximity of the fuel service panel to the fuel port. The AD requires that the fuel service panel maintenance light be disconnected.
Operators should note that this airworthiness directive applies only to the CL-604 variant of Bombardier Model Canadair CL-600-2B16 series airplanes.
This is considered to be interim action until final action is identified, at which time the FAA may consider further rulemaking.
Since it was found that immediate corrective action was required, notice and opportunity for prior public comment thereon were impracticable and contrary to the public interest, and good cause existed to make the AD effective immediately by individual notices issued on January 7, 2000, to all known U.S. owners and operators of the CL-604 variant of Bombardier Model Canadair CL-600-2B16 series airplanes modified in accordance with Supplemental Type Certificate SA8060NM-D, SA8072NM-D, or SA8086NM-D. These conditions still exist, and the AD is hereby published in the Federal Register as an amendment to section 39.13 of the Federal Aviation Regulations (14 CFR 39.13) to make it effective to all persons.
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.
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 2000-NM-05-AD.” The postcard will be date stamped and returned to the commenter.
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 Start Printed Page 3381Policies 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.Start List of Subjects
