## Abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Bombardier Model CL-600-2C10 (Regional Jet Series 700 and 701) series airplanes, that currently requires revising the Airplane Flight Manual to address uncommanded transfer of fuel between the wing fuel tanks and the center fuel tank; revising the Minimum Equipment List; limiting airplane operation; and increasing normal mission fuel requirements by 3,000 pounds. This amendment retains the requirements of the existing AD, and adds requirements for modification of the fuel distribution system for the center tank; and an inspection of that system for discrepancies, and corrective actions if necessary. This amendment is prompted by reports of uncommanded fuel transfer between wing fuel tanks and the center fuel tank, and reports of misaligned or damaged fuel tubes due to vibration. The actions specified in this AD are intended to ensure that the flight crew has the procedures necessary to address uncommanded fuel transfer; and to detect and correct discrepancies in the fuel distribution system, which could cause the center tank to overfill and fuel to leak from the center tank vent system or to become inaccessible, and could result in engine fuel starvation.
