Summary
This amendment revises an existing airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2B16 series airplanes, that currently requires disabling the remote fuel/defuel panel in the cockpit; and provides for an optional modification of the remote fuel/defuel panel, which would terminate the requirement to disable the panel. This amendment reduces the applicability of the existing AD. This amendment is prompted by reports of in-flight failure of the panel that resulted when a circuit breaker on a battery bus opened due to insufficient current flow capacity. The actions specified in this AD are intended to prevent the circuit breakers from opening during flight, which could result in irreversible loss of engine indicating and fuel quantity systems in the cockpit.
Rule preamble
The FAA’s background, reasoning and cost estimate, published with the AD.
Supplementary information
The FAA published this direct final rule with request for comments in the Federal Register on March 27, 1998 (63 FR 14804). The FAA uses the direct final rulemaking procedure for a non-controversial rule where the FAA anticipates that there will be no adverse public comment. This direct final rule advised the public that no adverse comments were anticipated, and that unless a written adverse comment, or a written notice of intent to submit such an adverse comment, was received within the comment period, the regulation would become effective on June 25, 1998. No adverse comments were received, and thus this notice confirms that this final rule will become effective on that date. Issued in Renton, Washington, on May 5, 1998.
